Explain how group behavior affects the survival and reproduction of Herring Gulls. Support your answer with evidence from the information above and your knowledge of science​

Answers

Answer:

The tapping behavior is innate, or genetically preprogrammed. Herring gull chicks will peck at the red dots of their parents' beaks without any prior training. In fact, a baby herring gull can be tricked by a yellow stick adorned with a red dot—it will peck at the stick just as eagerly as it would at a parent's beak.^2

squared

This is just one example of an innate behavior, or behavior that's genetically hardwired in an organism. Given the right cues, an organism will perform an innate behavior without the need for prior experience or learning. Innate behaviors tend to be very predictable—like the herring gull tapping—and they are often performed in a very similar way by all members of a species.

Explanation:

i think this might be the awnser

Long-term and comparative studies of Herring Gulls are being conducted in many parts of the world, including in the Great Lakes, New Jersey, and in Europe. Studies by my research group in New Jersey will be used to illustrate the kinds of studies that can be conducted with Herring Gulls to examine behavior, ecology, and the effects of human disturbance and contaminants on behavior and ecology. These studies provide paradigms for the study of Herring Gulls elsewhere, other birds and other vertebrates elsewhere, and in some cases, serve as models and sentinels for understanding the exposure and effects of contaminants on human behavior.

Compare and contrast the structure and function of arteries and veins throughout the cardiovascular system.

Answers

Answer:

Arteries carry blood away from the heart, and veins carry blood towards the heart. With the exception of pulmonary blood vessels, arteries carry oxygenated blood and veins carry deoxygenated blood. Arteries have thick walls with muscle tissue. Veins have thinner walls and use valves to keep your blood flowing.

Explanation:

Arteries Away
Veins towards
Larges lumen in veins so more blood can flow
Thicker walls in artery to withstand high pressure
Endothelial cells to allow the artery to spring back into shape
Artery oxygenated
Veins deoxygenated
Veins have valves to ensure deoxygenated blood (at low pressure) doesn’t flow backwards
Both have smooth walls to avoid turbulent blood flow

Why do the principles of relative dating not indicate the absolute age of a rock unit?

Answers

Answer:

Remember that in relative dating, scientists do not determine the exact age of a fossil or rock. They look at a sequence of rocks to try to decipher when an event occurred relative to the other events represented in that sequence. The relative age of a rock, then, is its age in comparison with other rocks.

Explanation:

In relative dating, scientists do not determine the exact age of a fossil or rock.

What is Relative dating?

They look at a sequence of rocks to try to decipher when an event occurred relative to the other events represented in that sequence. The relative age of a rock, then, is its age in comparison with other rocks.

Absolute dating and relative dating are the two types of dating techniques employed by archaeologists. Using the relationships between objects, we can tell which ones are older or younger.

Archaeologists can use this relationship to determine that artefacts discovered far below the surface are older than those discovered near to the surface.

Therefore, In relative dating, scientists do not determine the exact age of a fossil or rock.

Introduction: Over 80% of our energy comes from the burning of fossil fuels such as oil, gas, and coal. Fossil fuels are fairly cheap and plentiful, but there are several problems:
Fossil fuels are nonrenewable resources. That means there is a limited supply. Once the world runs out, there is no way to get more.
Burning fossil fuels adds carbon dioxide to the air. Most scientists agree that this causes the gradual warming of Earth’s climate, or global warming.

Question: What types of energy do not harm our environment?

Describe: Four examples of renewable resources are featured in the Energy Conversions Gizmo. These resources are produced all the time, so they will not run out. Read about each energy source, and then explain how each is produced in your own words.

Answers

Answer:

So your answers would be, A ( wind power) , B(water power), C ( solar power)

A ( wind power) is produce by blades to collect kinetic energy from the wind. The wind puts lift on the blades, causing them to whirl.The blades are connected to a drive shaft that spins an electric generator that generates electricity.

B ( water power) is produced by water power plants, water flowes through a pipe and pushes the blades causing a turbine to spin and to produce eletricity.

c ( solar power) is cause by " nuclear fusion"  which takes place in the sun. Protons from hydrogen atoms fuse to generate helium atoms when they collide violently near the sun's core. This process, known as a PP (proton-proton) chain reaction, generates a tremendous amount of energy.

structure

to store information for the cell

Answers

Answer:

to speed up cellular processes, structure

Explanation:

Typically proteins are not used for energy in organisms. Enzymes are proteins that speed up the cellular processes in our bodies. Proteins are also needed for the structure and function of body tissues and organs. Proteins do not store genetic information, that is DNA's job.

Answer:

Considered "the building blocks" of living organisms, proteins direct many of the most basic functions in organisms from the transport of oxygen, to the building of tissues to the replication of DNA. These large molecules are found in all of the cells in the human body.

Explanation:

Proteins are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body’s tissues and organs.

Answers

Wind power:

Advantages:

-Using wind as a source of power is very cost-effective. This is method is fuel free and the electricity harvested from wind farms is sold at a fixed price over a long period of time.

-Wind power is a clean fuel source. Using wind as a source of power prevents air pollution unlike power plants that mostly rely on fossil fuels which releases toxins into the hair causing both environmental and health problems.

-Wind power is a sustainable source of power since nothing can really stop it from being produced. Since this source of power relies on air, as long as there is air, energy can be harvested.

Disadvantages:

-Wind turbines are usually built in rural areas due to the size of them and the amount of space needed to build them. Because of this, they aren’t usually close to cities or remote locations where the energy harvested from them is most needed.

-Wind turbines can harmfully impact nature. Because of their height and size, many birds and other flying animals end up getting killed by the spinning blades connected to the turbine.

-Locations to build wind turbines may be hard to get due to competition with other things that may be of more importance on the land compared to wind farms.

Genes and Proteins in Hemophilia
Genetic researchers at Bay Medical Company are working to improve treatments for hemophilia. Currently, they are investigating the possibilities of gene therapy, which involves changing a person’s genes so that that person no longer has hemophilia. In order to help Bay Medical Company with their research, read the passage below and then answer the question.

Genes are instructions for proteins. Your traits are determined by the kinds of proteins your body makes. For example, when you get a cut, clotting factor proteins connect to form scabs. People with hemophilia do not have a version of the gene with the right instructions for making clotting factor VIII protein. Without the right instructions, their cells can’t make the proteins needed to form scabs. Healthy people have at least one copy of the gene that provides the right instructions for making all of the clotting factor proteins.

If genetic researchers found a way to change a person’s genes, would they be able to cure hemophilia? Why or why not?

Answers

Yes because it would divulge into a new method of science where we would be able to switch out the genes of people with hemophilia for a healthy gene which could possibly cure hemophilia.

Although, like human beings, they aremammals, they have adapted surprisingly well to an environment completely differentfrom our own. There is no doubt that people love these aquatic creatures, consideringthem to be both intelligent and beautiful. This fascination with dolphins is not a novelty;they have delighted people for centuries and they occupy a special place in folklorearound the world. For example, the ancient Mediterranean cultures believed that thedolphin represented the vital power of the sea, and early Greek mythology describesmany encounters between their gods and dolphins. Dolphins graced many forms of art inancient societies. Killing a dolphin was punished by the death penalty. Around the world,many cultures believed that any intentional harm done to a dolphin could cause ill-fortuneor mortal sickness.Dolphins are able to make sounds in the form of little clicks, through which theycommunicate with each other. Many dolphins are able to leap high out of the water,sometimes to indicate the presence of fish to their companions, and sometimes simplyout of exuberance. As well as making clicking sounds, they make other sounds whichdamage the balance of their prey, making it easier to capture. They are also able to workout where their prey is by listening to the echoes of the sounds which their prey makes.This special ability is called echolocation, and it enables dolphins to explore theirenvironment over a wider distance than eyesight allows, and to find their prey in a dark,watery world where sight is often of little use.Modern, efficient methods have been introduced that allow fishermen to bring in recordcatches. However, these methods make no distinction between fish and dolphins, so thatthe latter then often become the victims of these environmentally destructive fishingmethods.In some parts of the world, fishermen have noticed that particularly large tuna fish swimunderneath dolphins. Realizing, therefore, that financially rewarding catches of tuna fishawait those willing to take advantage of the tuna-dolphin bond, the fishermen deliberatelynet these dolphins in order to catch the tuna swimming below them.Modern fishing nets, unlike those in even the recent past, are made of very strongmaterials which dolphins can neither detect nor break and, in some places, localfishermen use these nets with the specific intention of catching dolphins for food.
