More than 1 washed up on a beach in Ireland… close to some big jellyfish


Gooseneck barnacles

It appears to be a cluster of goose barnacles washed up onshore. This is based on the thick, distinct pedicle and the general shape of the asymmetrical valves. Without more information, that's as accurate as I can probably get you.


What is Marine Biology? (with pictures)

Marine biology is the study of life forms living in saltwater, and therefore, usually an ocean environment. Studies in this field may include the analysis of plants, fish, microscopic organisms and marine mammals. Marine biologists may also study the whole of an ocean ecosystem, or a specific type of life form and how it interacts with its habitat.

People who work in marine biology may do so in the field or analyze data gathered from ocean sites. It can be comparative in nature, and might include an analysis of similar bacteria existing in several different oceans. Alternately, it can be specific to just one species or location.

Other forms of science, particularly climatology as it affects ocean life forms, oceanography, and animal behavior, are connected to the field. While some marine biologists may study the biological structure of an animal, others might study how it behaves.

Often people think of marine biology as only the study of marine mammals, like whales, dolphins or seals. This actually represents just a small portion of the scientific field. There are relatively few marine mammals as compared to vast numbers of species of fish, plants, and single-celled organisms in ocean environments. Understanding the mechanism and interactions of these less glamorous species tend to shed light on important facts about the marine mammals that do exist.

Marine biology may also involve a certain amount of activism. Many scientists who consider themselves marine biologists have amassed a great deal of additional scientific education. This is because the field must be understood in the context of other sciences. In addition, if one wants to become engaged in protecting the ecosystems of the ocean, writing and speaking skills are immensely important.

Not everyone who studies marine biology does so at the ocean, and there are a number of sites of study in landlocked states or countries. This is because oceans and their lifeforms have an effect on all areas. Prehistoric biology may also evaluate the specimens of extinct ocean life forms that are present in areas where no saltwater bodies still exist.

Experts in this field may also the study how the organisms in the ocean may benefit human life. The oceans’ many different life forms may hold potential health benefits, give keys to developing beneficial medications, or help scientists determine how best to protect earthbound life forms.

Some find marine biology particularly appealing because so many of the ocean’s species remain unknown. There are ocean areas that people still cannot access because of temperature or depth. The ocean is a frontier that humans have not yet breached, so people in the field regularly have the opportunity to be a part of earth and life science studies that lead to brand new discoveries.

Women in environmental biology

Have you ever wondered how humans relate to other living beings and what do you need to know to be able to understand current environmental problems? Do you know that many of these researches and knowledge have been described by women?

This course gives answers to these questions and it is addressed to anyone interested in the relationship between humans and other living beings, as well as all those concerned about the global change situation that the planet is suffering. We will learn key concepts of environmental biology, what does the word biodiversity mean, what are the main types of living organisms that exist on the Earth and the importance of these for human beings. We will also learn that the gender perspective plays a key role in how we understand the world and in how science, and in particular, environmental biology, progress. What is this course useful for? In the current context of global change of the planet, sustainability is a key and transversal concept in many aspects of our life: education, politics, legislation, etc . Knowing to appreciate the importance of our relationship with the natural environment will facilitate to work on issues related to sustainability with a solid knowledge based on evidence. On the other hand, there is growing evidence that the gender perspective is a key element in the transformation of many environmental problems on the planet. This course has been designed and developed by a team of women researchers applying the gender perspective in the content and structure of the course. In addition, with this course you will discover many other women who, throughout history, have made key contributions to environmental biology and that will surely allow you to start stretching the thread to know more of them.

What Are Some Important Reasons for Studying Biology?

Biology plays an important role in the understanding of complex forms of life involving humans, animals and plants. Understanding these intricate details of life helps humans understand how to care for themselves, animals and plants in the proper manner. Biology helps individuals understand the interaction between humanity and the world. It also develops interests in the lives of living organisms in an effort to preserve them.

Through studying biology, pathologists understand the human body, the functions of various organs, how diseases affect the body and ways to effectively control diseases. Veterinarians have to study biology to appreciate the functions of animals, including marine animals and creatures that live on land. Environmentalists rely on the study of biology to learn how man’s actions affect his surroundings and the ecosystems of other living beings.

Studying biology is the foundation of all characteristics of life on Earth. Apart from creating solutions to the challenges many living organisms face, it paves the way for inventions and discoveries that improve the quality of life. Without studying biology, humans would probably never realize how important maintaining a healthy ecology is for themselves, animals and plant life. Additionally, studying biology enables the use of forensics to trace and arrest errant members of the society. It also allows agriculturalists to rear unique breeds of plants and animals.


What's on the Biology SAT II?

Here's a content overview provided by the College Board that lists the division of topics for each version of the Biology SAT Subject Test:

From the chart, you can see that many more questions are devoted to Cellular and Molecular Biology on the Biology-M test, and many more are devoted to Ecology on the Biology-E test.

Notice that Biology M also has slightly more questions on Genetics, whereas Biology E has slightly more questions on Evolution and Diversity. Both tests have the same number of questions dealing with Organismal Biology. These topics should all be familiar to you if you've taken a biology course.

The types of skills tested on both Biology-E and Biology-M include the following:

  • Recalling fundamental concepts and specific facts (about 30% of test)
  • Applying biological knowledge to practical scenarios presented on the test and solving problems using mathematical relationships (about 35% of test)
  • Making inferences and forming conclusions based on qualitative and quantitative data (about 35% of test)

Essentially, 70% of questions will present a scenario and then ask you to make deductions or calculations based on it. The scenario could be a chart of bacteria growth or a description of a lab procedure. It's important to know the fundamental parts of an experiment (independent and dependent variables) and be able to project your understanding onto unfamiliar situations.

The other 30% of questions just ask you to recall biological facts directly. I'll provide examples of different types of questions you can expect to see on the test in the next section.

You might see questions about changes in species population density in a particular ecosystem. It's the ciiiiiircle of liiiiiiifeeeee!

It is an Azalea!


Synthetic biology incites natural products industry into action

In many ways, the synbio issue has caught the natural products industry flat-footed. There is also some disagreement as to whether synbio is such a bad thing. “There is definitely a generational issue in the industry,” Lewis says. “Old-school industry founders and keepers of the flame tend to be much more concerned about this. They are well aware that this is what they were fighting against all along, just under a new name.”

But Lewis believes industry must strengthen its resistance to ensure its very survival. “As an industry that supposedly believes in working within natural boundaries and laws, we are incredibly weak at countering the synbio narrative that it will fix all the problems,” he says. “If we don’t stand up and say we will judge the value of how each technology is applied, we will end up without a natural products industry.”

To stem the adoption of synbio, industry first must call it out for what it is. “Stakeholders must agree on a definition for new genetic engineering and that the outcomes are in fact GMOs,” Eisenbeis says. “Then industry can work to keep them out of the supply chain by putting in place checkpoints throughout.” This will involve setting standards that extend beyond those covering traditional GMOs.

Individual companies can do their part by knowing how their ingredients are produced and from where they are sourced. “Companies need to be very clear about what is acceptable in final products,” Perls says. “If they are trying to be truly natural and sustainable, they must ask very specific questions of ingredient suppliers and ask that they not be offered any ingredients derived from genetic engineering.”

Finally, consumer-facing brands must be transparent with shoppers about their ingredients’ integrity. To that end, seeking Non-GMO Project verification, along with USDA Organic certification, is highly valuable.

“People are very clear that they want real food and transparency,” Perls says. “We saw what happened with the first generation of GMOs where companies had to rush to remove them from their products.”

Indeed, once Campbell, Nestlé and other big food corporations embraced consumers’ desire for GMO labeling, several defected from the Grocery Manufacturers Association citing its resistance to transparency. Ultimately, this brought GMA to its knees, forcing the 100-year-old trade association to regroup and rebrand. If consumers discover the built-on-trust natural products industry isn’t standing against synbio, or at least being transparent about it, it could face a similar crisis.

“The writing is on the wall,” says Perls. “These are genetically engineered products, or derived from genetic engineering, and should be labeled as such.”

Hi. I am currently doing A level Biology and I seem to be having problems with application questions. What do I need to do?

    . If Biology is the only subject you are self-studying, you can cover the entire syllabus in 6 weeks (13 pages a day for 45 days). It will take an additional 3 weeks to complete past papers and skim through the content again to fill in knowledge gaps. So, you can be A* ready in 9 weeks. If you are self-studying alongside school and other subjects, it may take you up to 18 weeks. What method should you use? The Scribble Technique – exactly how its outlined above.

2. Bad grades – failing my first year in itself was in itself motivational. The sting of those bad grades combined with the inspiration from my mentor created the perfect conditions for change.

3. Written down plan – from year 9 to 12 I never really bothered to figure out how to learn properly. That changed after results day. I read books on memory and learning, discovered the Scribble Technique and spoke to successful students from the year above. This all went into a written plan which I continuously referred back to throughout the year. My book How to ACE Your A-Levels is essentially a detailed/updated version of this plan.

4. Experiments – I was so annoyed at myself for failing, that I set extreme targets like ‘learn the entire Biology textbook using the Scribble Technique’ in a month then do a past paper. These were essentially experiments to see if I was actually smart enough to get As-A*s and also to test my study techniques. When I could see the methods working and my marks improving, the little voice in my head that kept telling me I wasn’t good enough became much quieter. I started fantasising about good grades instead of fearing bad grades, and the rest was history.

    6 weeks before her Biology A-level exam. As suggested by Yojana, she revised her textbook at a rate of 21 pages a day using the Scribble Technique. We called her at the end of each day to test her knowledge. She was done by week 4, completed all the past papers by week 6 and secured an A*.

To do what she did, you need to use the Scribble Technique properly and not glaze over the page without trying to understand the information. When we asked her to explain the information she learnt back to us at the end of each day, she nailed almost every single bullet point. This takes practice and coaching from an expert tutor or academic coach.

Use the Scribble Technique to learn the content in your textbooks and attempt all the practice questions at the end of each topic.

    to identify the best learning resource and calculate your daily page target.
    2. The Scribble Technique to learn each page.
    3. After you’ve finished the textbook, work through all the relevant past papers slowly and mark the short answer questions yourself. Get a teacher/tutor or us to mark your long answer/essay questions.

If you’re struggling to hit your daily page target, seek help! Don’t wait for the problem to fix itself.
