The function of the placental hormone human placental lactogen (hPL) is to ________. Question 12 options: prepare the breasts for lactation nourish the placenta regulate the menstrual cycle help the placenta to mature All of the above are true.

Answers

Answer:

nourish the placenta

Explanation:

The hormone called human placental lactogen (hPL) is a hormone secreted by the placenta, which functions to supply nutrients and oxygen to the growing fetus in the womb.

The human placental lactogen is produced to help in the efficient use of ingested food substances in the production of energy (metabolism). This indirectly helps to nourish the placenta because if the mother efficiently converts food into nutrients, the placenta is also adequately nourished.

What differences would you expect to see in a population made up of individuals whose chromosomes experience crossing-over frequently compared with a population made up of individuals whose chromosomes do not cross over? Please explain your reasoning.

Answers

Explanation:

Crossing over is a type of recombination that occurs during prophase I of meiosis and results in the exchange of genetic material between homologous chromosomes. In a population where crossing over occurs frequently, there would be increased gene pool or genetic drift and variations compared to a population where individual chromosomes do not cross over. The offspring will be genetically unique because of crossing over and independent assortment.

Question 7(Multiple Choice Worth 4 points)
(01.03 MC)
The evolution from vesicles to true cells was enabled by the development of

A) a membrane separating the cell from its environment
organic molecules, such as carbohydrates and lipids

B) self-replicating molecules, such as RNA and DNA
Thing

C) inorganic molecules, such as nitrogen and oxygen

Answers

Answer: The correct option is B (self-replicating molecules, such as RNA and DNA)

Explanation:

The current theory of the process of evolution makes use of present day knowledge of genes and chromosomes to explain the source of genetic variation upon which natural selection works. These genes are discrete units of inheritance which determine hereditary characteristics. All the information for the inheritable characteristics of an individual are contained in these genes.

When a cell divides, the genes duplicate themselves so that each daughter cell has an identical set of genes as the original parent cell. These genes are passed from parents to offspring in the gametes of the parents.

Gene are found in the DNA( Deoxyribonucleic acid) molecules or RNA (Ribonucleic acid) molecules. These molecules are capable of self replication due to a process called mutation. Mutations are random changes in DNA that alter genetic information and sin introduce new characteristics. They may occur

--> in body cells or

--> during gamete formation.

Thus, evolution from vesicles to true cells is through self replicating molecules through the process of mutation which is the raw material for evolution

Answer:

B (self replicating molecules such as RNA and DNA)

There are a lot of cells and tissues that support the developing embryo. How do you think this changes if the mother is a litter bearing animal such as cat, dog or mouse? (be sure to provide references to defend your answer

Answers

Answer: The cells and tissues support embryonic development in mammalian offsprings as these cells have the capacity to divide and differentiate.

Explanation:

Since the time from copulation till delivery of fetus several changes occur in the body of the mammalian mother including animals like cat, dog, and mouse to support the pregnancy. There are specialized totipotent cells which are proliferating specialized cells they have tendency to divide quickly and differentiate into functional types so that they can become a specialized organ or part of the body. If take an example of human which is also mammal in mother body after conception the egg gets fertilized to form sperm which changes to embryo the embryo divides and differentiate to form blastocysts and further divides and differentiate in several stages to become fetus.

The phenomenon of single or double fertilization is unique to the seed plants

Answers

Answer:

Double fertilization

Explanation:

The phenomenon of double fertilization is unique to flowering plants (i.e., angiosperms). Each pollen grain produces two male gametes (sperm cells), one of which fertilizes the egg to form the zygote, whereas the other sperm fuses with polar nuclei in the female gametophyte in order to form a triploid cell (3n) called endosperm. Subsequently, this endosperm will support embryonic growth by supplying storage nutrients and by serving as a mechanical barrier during seed development and germination.

Checkpoint proteins at the G1, G2, and M phases of the cell cycle monitor whether crucial cellular process have been completed correctly and the cell cycle can proceed. A mutation in a checkpoint protein can lead to cancer by resulting in the checkpoint protein not functioning properly. Which of the following could be a result of the improper functioning of a checkpoint protein in a cancer cell?

a. Cell division stops.
b. The cell reverts to interphase.
c. There is uncontrolled cell division.
d. The cell dies.

Answers

Answer:

c. There is uncontrolled cell division.

Explanation:

There is uncontrolled cell division that result in the improper functioning of a checkpoint protein in a cancer cell because checkpoint protein monitors and control the the process of cell cycle. If mutation occurs in this checkpoint protein, the cycle is no longer in control which leads to the uncontrolled cell division and we also know that cancer is a disease which occurs due to uncontrolled division of the cell.

A 53 year old man presents with increasing gastric pain and is found to have a 3 cm mass located in the anterior wall of his stomach. This mass is resected and histologic examination reveals a tumor composed of cells having elongated, spindle-shaped nuclei. The tumor does not connect to the overlying gastric epithelium and is instead found only in the wall of the stomach. The tumor cells stain positively with CD117, but negatively with both desmin and S-100. Special studies find that these tumor cells have abnormalities of the KIT gene. Which of the following is the most likely diagnosis?

a. Lymphoma of mucosa-associated lymphoid tissue (MALToma)
b. Ectopic islet cell adenoma (VIPoma)
c. Gastrointestinal stromal tumor (GIST)
d. Submucosal leiomyoma ("fibroid tumor")
e. Nonchromaffin paraganglioma (chemodectoma)

Answers

Answer:

The correct answer is c. Gastrointestinal stromal tumor (GIST)

Explanation:

Gastrointestinal stromal tumors (GIST) are rare neoplasms that originate from mesenchymal cells, generally express the KIT receptor (CD117) and present activated mutations of the tyrosine kinase or tyrosine kinase receptor proto-oncogene, cKIT (it is the gene that encodes KIT protein synthesis). GISTs can be located in any portion of the wall of the GI tract, but most are located in the submucosa or in the muscularis propria. Some are predominantly extramural; large ones can infiltrate neighboring organs

A gastrointestinal stromal tumor (GIST) is the most likely diagnosis (Option C).

Cancer is a multifactorial disease in which cancer cells divide and proliferate to produce a tumor.

Cancer is often associated with mutations in key genes which are required for the normal functioning of a given tissue (e.g. cell cycle genes).

A gastrointestinal stromal tumor (GIST) is a tumor in which cells of the stomach proliferate in an uncontrolled manner.

In conclusion, a gastrointestinal stromal tumor (GIST) is the most likely diagnosis (Option C).

[tex]\sf[/tex] what is meaning of acceleration?​

Answers

Acceleration is the rate at which velocity changes with time. For example if an object was falling with no air resistance the only force acting upon it would be gravity therefore the vertical acceleration of the object would be -9.8 m/s^2. Also isn’t this supposed to be a physics question and not biology lol

Answer:

The rate at which an object's velocity changes with respect to time is called acceleration. Accelerations are measured in terms of vectors. The orientation of an object's acceleration is given by the orientation of the net force acting on that object.
