The Canada lynx is a rare wildcat in Minnesota. The lynx has large "snowshoe' like feet that enables it to walk on top of deep, soft,
snows. Snowshoe hares are also common in the area. According to the graph of the interactions between the lynx and the hare, what
best describes their ecological relationship?

A)
Mutualism

B)
Predator/prey

C)Parasite/Host

D)
Interspecific competition

Answers

Answer: B)  Predator/prey

=========================================================

Explanation:

The lynx is the predator that hunts and eats the snowshoe hare, which is the prey.

The graph shows that when the hare population is large, so is the predator population because they rely on the hares as a source of food. However, the more predators there are, the less prey there will be. This causes the prey population to decrease. In turn, this decrease causes the predator population to decrease as well. If there's less food, then some of the lynx population will starve to death.

At some point, the hare population will rebound and go back up due to less predators eating them. They have a better chance to survive. As the hare population goes up, so does the lynx population. They're both strongly linked together, and we have this cyclic pattern the graph indicates. You could say this is "the cycle of life" or "cycle of nature" so to speak.

This is a very simplistic viewpoint because it does not account for other factors such as other predators and other prey, and it also doesn't take account of things like habitat loss for instance. Despite that, such predator-prey models are still useful to understand the connection between the two species.

Protein are digested and transported by fellow proteins. Give vivid example to support the statement

Answers

Answer:

Proteins are digested in the body when ingested food from a protein source, is broken down in the stomach by enzymes like Chymotrypsin, trypsin which are both proteins, their common goal is to convert protein into a more simple form or simplest form ( Amino acids). This enzyme (Chymotrypsin and trypsin) are Proteins and they act as biological catalysts that are responsible for breaking proteins down.

An example of how Proteins are transported by fellow proteins is the case of Ferritin. Ferritin is an essential protein in the cell of the body that regulates the amount of iron available to the body. This is important for the hemoglobin in red blood cells.

Student B: "The purpose of translation is to make a duplicate copy of DNA."


Which statement about the students’ comments is correct?

Student A is incorrect, because the purpose of translation is to convert DNA to RNA.

Student B is incorrect, because replication is the process that makes a duplicate copy of DNA.

Student A is correct, because translation occurs in the nucleus.

Student B is correct, because the DNA must be copied before mitosis.

Answers

Student A is correct in the definition and purpose of translation.

The study of genes and inheritance is called genetics.

The correct answer is option B.

The translation is defined as the process in which mRNA is read by the ribosome and gets the amino acid to form the polypeptide and protein. Student two claimed is the process replication.

Replication is defined as the process of formation of new DNA from the old DNA.

According to the student, student 1 is correct.

Explanation:

The rough endoplasmic reticulum produces proteins and the Golgi apparatus packages and transports the proteins.

The functions of the rough endoplasmic reticulum (RER) and Golgi apparatus is to process the protein, synthesis of protein for cell secretion. Thus option D is correct.

what is the function of Golgi apparatus ?

The Golgi apparatus is present in eukaryotic cells have the structure of stacks of membranous sacs; The Golgi apparatus modifies, sort and transport the proteins for the secretion.

These are membrane-bound organelle present in the cytosol of eukaryotic cell.

It involves modification of the proteins, sorting  and packaging them, and it mainly comes from the endoplasmic reticulum. The folds like cisternae of the Golgi involved in the transport of molecules and producing lysosomes.

It packages the proteins into membrane-bound vesicles transported to various organelles like lysosomes, plasma membrane or secretion; it also take part in the transport of lipids and the formation of lysosomes, it also serves as the site of synthesis of various glycolipids, sphingomyelin, etc.

Thus option D is correct.

Which term refers to a fertilized egg after the cells have begun to differentiate?

A. Blastocyst

B. Fetus

C. Embryo

D. Zygote

Answers

Answer:

D

Explanation:

Blastocyst refers to a fertilized egg after the cells have begun to differentiate. So, the correct option is A.

What is Blastocyst?

A ball of cells known as a blastocyst develops in the first five to six days of pregnancy, shortly after a sperm fertilizes an egg. It embeds itself in the uterine wall, developing into an embryo and subsequently a fetes.

A healthily developed embryo will include six to ten cells three days following fertilizations. The fertilized egg develops into a blastocyst, a rapidly growing ball of cells, on the fifth or sixth day. The innermost collection of cells will develop into the embryo. The outer group will develop into the cells that support and safeguard it.

Within the first two weeks following conception, a developing, fertilized egg is known by a variety of names, include zygote, morula (day 4), or blastocyst (day 5). About 10 weeks after the previous menstrual cycle, or 8 weeks after conception, the embryonic period begins.

Therefore, the correct option is A.
