Answer: Lichens affect every species in the ecosystem, in 2013 Russia had a dramatic lichen die off which caused 61,000, 20% of the entire reindeer population to die from starvation. And with fewer deers, the bears and wolves also suffered from the loss of lichens and if it takes a long time for lichens to grow back in an ecosystem, animal declines may take years if ever to be corrected. Lichens serve as a basis for several food chains, especially in artic communities.
The argument which shows why lichens are necessary to establish a new ecosystem is as follows;
Lichens are known to enable algae to live all over the world in many different climates.
On this note, lichens also provide a means to convert carbon dioxide in the atmosphere through photosynthesis into oxygen, a process required by all to survive.
Additionally, lichens provide us with valuable information about the environment around us.
On this basis, lichens are important for establishing a new ecosystem after an extreme disturbance.

Construct an argumentative paragraph. Do you believe it's ethical or unethical to artificially select traits in plants and or animals? Provide evidenco to suoport your claims. It doesn't matter what side you chose, but I need it asap.I will give you any mark you want.
Answer:
The ethics of artificially inserting traits in animals has been in the practice for years in the form of selective breeding, but should scientists really be editing DNA to the extent they are today? I don't believe they should. Life itself should construct itself without us interfering. Making a brand new plant just because it looks nice doesn't account for many factors, including the fact that it could be harmful to nearby plants if pollinated. In addition, generic engineering costs quite a lot of money, which should be used on other more cost effective methods, such as improving agriculture rather than creating a whole new plant that could harm entire crops. Genetic engineering isn't a necessity and humans should not play God with plant and animal life.

How can you determine the number of bonds an atom can make
Answer:
The number of bonds for a neutral atom is equal to the number of electrons in the full valence shell (2 or 8 electrons) minus the number of valence electrons. This method works because each covalent bond that an atom forms adds another electron to an atoms valence shell without changing its charge.

Please help!!!! Grizzly bears and polar bears are very closely related, so much so that they can reproduce to form hybrid offspring. Use your understanding of natural selection to describe how polar bears became a separate classification from the grizzly.
Scientists believe that at first these bears scavenged seal carcasses that had washed ashore, and gradually began to hunt the seals by waiting at the water's edge as the seals surfaced to breathe. This is believed to be an important step in the evolution of a new bear species, the polar bear
Over time the new polar bears were used to the cold climate and learnt how to fish, they then separated from the grizzly bears, they developed new creatures which would help them survive in one of the most dangerous climate.
Polar bears become separate classification from the grizzly by the natural selection known as divergent and adaptive evolutionary change.
Polar bears and grizzly bears are considered as closed to one another so they can interbreed. They both diverged from one another due to the harsh climate of the Arctic and the ecology of the region.
The changes that took place are camouflaging and pigment-free fur-coat that helped them in order to adapt to the different climates.The genetic mutation leads to such Adaptive changes when the polar bears migrated northwards.The populations living in different climates undergo natural selection that is divergent natural selection and the adaptive evolutionary changes that result in different species.Learn more about speciation:

B cells can divide to form plasma cells. Each plasma cell contains many mitochondria
and an extensive endoplasmic reticulum. Referring to the function of plasma cells in your answer, explain why these features are important adaptations.
Answer:
Explanation:
The presence of mitochondria and an extensive endoplasmic reticulum are the features that are important for adaptations of the plasma cell because plasma cells (white blood cells) secrete immune proteins also called antibodies which only formed due to the presence of endoplasmic reticulum whose function is to formed proteins for the cell so that's why plasma cells have large sized endoplasmic reticulum.

Which answer choice accurately depicts the sequence by which blood moves from the pulmonary vein to the body tissues?
Answer:
See the answer below
Explanation:
Oxygen-rich blood flows from the lung through the pulmonary vein to the left atrium of the heart. From there, the blood is pumped through the mitral valve to the left ventricle. The contraction of the left side of the heart sends the oxygenated blood out of the left ventricle through the aortic arch to the major arteries designated to carry blood to the major parts of the body. From the arteries, blood moves to the capillaries and then to the various tissues of the body before returning back to the heart through the vein.
Thus, the sequence of flow of blood from the pulmonary vein to the body tissues can be summarized as:
Pulmonary vein -> Left atrium -> Arteries -> Capillaries -> tissues

Which statement best explains how the gases of the atmosphere affect the temperature of Earth?
The atmosphere today contains more greenhouse gas molecules, so more of the infrared energy emitted by the surface ends up being absorbed by the atmosphere. Since some of the extra energy from a warmer atmosphere radiates back down to the surface, Earth's surface temperature rises.
