Which of the following correctly describes the arrangement of the phospholipids in the lipid bilayer of the cell membrane? *

Phospholipids line up head to head, so the phosphate heads are separated from water.
Phospholipids line up head to tail, because opposites attract.
Phospholipids line up tail to tail, so the fatty acid tails are separated from water.
Phospholipids line up with no pattern, because they're molecules which move randomly.

Answers

Answer 1

Answer:

Two layers of phospholipids where the outer layer has the hydrophilic heads facing toward the outside of the cell and the inner layer have the hydrophobic tails facing toward the inside of the cell.

Identifying an individual's genetically influenced health risks could increase their potential to achieve optimal health.

Answers

Answer:

Yes.

Explanation:

Yes, Identifying an individual's genetically influenced health risks could increase their potential to achieve optimal health because necessary steps can be taken in order to prevent the disease from more spreading and cause damaged to the body. Identification of genetical disease can be prevented to cause damage if the factors that triggers the disease can be avoided so we can conclude that identification of genetically influenced health risks can increase the chances of getting good health.

Quade is studying for an exam, which will cover neurons and action potentials. He has drawn a diagram that shows the segments of an axon, and he has noted that every time a segment fires, the _____ flood in from the outside of the cell, while the prior segment returns to its resting potential. Please choose the correct answer from the following choices, and then select the submit answer button.

Answers

Answer: positive sodium ions

Explanation:

This relates to the Action Potential which is what a nerve cell goes through when it needs to send information down the nerve cell to another cell and so on till it gets to the destination of the message.

The information is transmitted when the segments of the axon fire and when they do, positive sodium ions come in from outside the cell to the inside thereby making the inside positive. The previous segment would return to a resting potential when potassium ions which are negative, rush into the cell.

Deforestation occurs when large Amounts of trees are cut down and not replaced which of the following would result from deforestation


A. Decrease carbon in the atmosphere
B. Increased carbon in the atmosphere

Answers

Answer:

The correct answer is (B).

Explanation:

Deforestation occurs when large Amounts of trees are cut down and not replaced, which of the following would result from deforestation...

Increased carbon in the atmosphere

This statement is true because when trees become less abundant, the amount of oxygen being released into the atmosphere by trees via photosynthesis.

The circumstance that would result from deforestation is the increased carbon in the atmosphere. Thus, the correct option is B.

What is Deforestation?

Deforestation may be defined as the process of cutting down or eliminating trees in large numbers from our surroundings. This activity generally happens due to industrialization, wood extraction, urbanization, etc.

When the number of trees remains less in the environment due to deforestation or any other activity, the level of carbon dioxide in the atmosphere typically rises.

This is because carbon dioxide is considered the reactant of photosynthesis that is utilized by the plants along with water in the presence of sunlight and converted into oxygen.

But when the number of plants decreases, the level of carbon in the atmosphere increases, and the level of oxygen in the atmosphere decreases.

Therefore, the circumstance that would result from deforestation is the increased carbon in the atmosphere. Thus, the correct option is B.

A scientist is comparing the sequences of related genes among three species. Two of the species have very similar sequences, while the sequence of the third species differs greatly from the others. T

Answers

Hi. The question you presented above is incomplete. This makes it impossible for this question to be answered. However, when searching for your question on the internet, I was able to find another question exactly like yours, which asked you to explain the evolutionary relationship between these three species. If that's the case for you, I hope the answer below will help you.

In a simplified way, we can infer that among the three species presented above, the third presented a faster evolution than the first two and this is what explains the difference between the gene sequences between the species. As the question presents, the three species have related genes, which indicates that they had a common ancestor, however the difference in the gene sequence of the third species shows that it evolved first, showing changes that cannot be noticed in the first two species that are evolving more slowly.

What ideas were changing in the scientific community at the time of Darwin's travels? How might those new ideas influenced Darwin?

Answers

Answer and Explanation:

At the time of Darwin's travels, the scientific community was beginning to abandon ideas linked to creationism to adopt more scientific and testable concepts, less linked to religiosity. Darwin was very influenced by these new concepts and decided to study a way to apply them to the biological diversity that planet earth presented. He wanted to explain this diversity through scientific data, obtained by experiments and logical reasoning, without the interference of creationist concepts and that would show how life on earth changes over the years and how species of living beings were created. This was one of the kicks that made him start his travels and his studies on biological evolution.
