How do scientists use ice to study ancient climates
Answer: Ice is very important for studying ancient climates. Ice can preserve the remains of organisms such as a Wholly Mammoth, possibly for hundreds of thousands of years. The details and phenotype of the mammoth such as its fur, can provide evidence of Earth's ancient climate, and where it occurred (which is somewhere that contains ice).

FIRST PERSON TO ANSWER GETS BRANLYSEST After Hunter drank a glass of milk, sugar levels in his blood increased. This stimulated the hormone insulin to be released. Insulin helped the sugar move from his blood into cells, so his blood sugar levels decreased. Which statement explains what happened next? Positive feedback caused his pancreas to stop secreting insulin. Negative feedback caused his pancreas to stop secreting insulin. Negative feedback caused his pancreas to produce more insulin. Positive feedback caused his pancreas to produce more insulin.
Answer:
The correct answer B
When the body gets the glucose, the glucose in the blood increase then the hormone insulin is released so that the glucose from the blood can be transferred from blood into the cells of the body.
The release of hormone insulin is a positive feedback.
Once the glucose is transferred into the cells of the body then the negative feedback starts acting that stops the secretion of insulin from the pancreas.
What will happen next is that negative feedback would cause his pancreas to stop secreting insulin.
The maintenance of relatively constant internal body processes depends largely on negative feedback.
Negative feedback mechanisms ensure that setpoints are returned.
Hence, whatever causes setpoints to be breached is reversed or removed totally.
In this case, the continuous secretion of insulin will further lower the blood sugar level and causes the setpoint to be breached further. Thus, the actuator (insulin) has to be removed.

Answer:
Cementation
Explanation:
It may be harmful when people compete to see who can hold their
breath the longest under water. Without oxygen, brain cells
Answer:
tend to not get enough oxygen which may lead to severe brain damage and our brains can get Celebral Hypoxia which includes symptoms such as confusion and loss of coordination
Explanation:
When the brain cells receive less oxygen as required by the brain ; The brain suffers a severe damage due to brain hypoxia.
When one holds his/her breath under water the amount of oxygen flowing into the brain cells is cut off and if the oxygen supply is not restored within 5 minutes, the brain cells will start dying off which will result to severe brain damage and eventual death .
Hence we can conclude that When the brain cells receive less oxygen as required by the brain ; The brain suffers a severe damage due to brain hypoxia .

Which of the following are functions of protein molecules in an animal?
1. Protein molecules help cells carry out many of their functions, and they are part of body structures such as hair and nails.
2. Protein molecules help cells carry out many of their functions, but they are not part of body structures such as hair and nails.
3. Protein molecules do not help cells carry out many of their functions, and they are not part of body structures such as hair and nails.
4. Protein molecules are part of body structures such as hair and nails, but they do not help cells carry out many of their functions.
Answer:
1. Protein molecules help cells carry out many of their functions, and they are part of body structures such as hair and nails.
Explanation:
Proteins are one of the four major biomolecules in living systems. Proteins play a major role in the physiological, structural and metabolical processes in living organisms. They help cells carry out many functions when they acts as enzymes and hormones. Enzymes and hormones are proteinous chemical substances that catalyzes and speedens up physiological reactions respectively.
In addition, proteins are major structural components in animals. For example, keratin is a protein that makes up the hair and nails of animals. They provide structural support in parts of the body they are found.

Before mitosis begins, which happens before the nucleus starts dividing?
The DNA replicates.
The cytoplasm separates.
The sister chromatids separate.
The homologous chromosomes cross over.
Answer:
The DNA replicates.
Before mitosis begins, the DNA replicates. During the S phase of interphase, which precedes mitosis, the DNA in the nucleus undergoes replication, resulting in the formation of identical sister chromatids.
This ensures that each daughter cell produced during mitosis receives a complete set of genetic information.
After DNA replication, the cell enters the mitotic phase, during which the nucleus divides and the replicated DNA is distributed to the daughter cells.
The cytoplasm separates during cytokinesis, which occurs after mitosis and is not directly related to events before nucleus division. The separation of sister chromatids occurs during anaphase of mitosis, not before the nucleus starts dividing.
Thus, the process of homologous chromosomes crossing over occurs during meiosis, not mitosis.

The woolly mammoth was a relative of elephants that lived in the far north. There is much debate in the scientific community about what caused the extinction of mammoths. Climate models show that changing weather patterns stressed mammoth populations. Hunting by humans may have also reduced populations. The youngest mammoth remains on a continent are 10,000 years old.
Why did natural selection not cause mammoths to evolve new adaptations in response to environmental changes instead of becoming extinct?
A. There were too many offspring in the population.
B. There were too many different traits in the population.
C. There was not enough competition in the population.
D. There was not enough variation in the population.

This was simulation. What are some variables that this peppered moths simulation does not address?
Answer:
The simulation only shows how a population can change overtime in response to the changes in the environment. During the industrial revolution, one particular phenotype of moths had an advantage over the other and hence, was subjected to natural selection. What this simulation does not tell us is the causality and correlation aspect of the change that occurs in the moths. Correlation does not equal causation, and the simulation does not shed any light on these variables in this case.

Why is the point of attachment of the frog's tongue considered to be advantageous?
Answer:
Frog's tongues are attached to the front of their mouths rather than at the back like humans.
