Can someone describe these:
Menstrual Phase
Follicular Phase
and Luteal phase

Thanks!!!

Answers

Answer:

(menstrual phase) this is the phase where the unfertilized ovum and endometrium that was formed in readiness for implantation slough off or come out due to a sudden drop in progesterone levels

(follicular phase) this is where the graafian follicle in the ovary develops. from primary follicles due to secretion of follicle stimulating hormone by the pituitary gland and matures there after due LH hormone which will also stimulate the ovary to release the ovum

(luteal phase)this is the phase after the ovum has been released where the remains of the ruptured graafian follicle undergo reorganization to form a corpus luteum/yellow body which now produces progesterone which causes thickening of endometrium in readiness for implantation

hope this helps

Answer:

The menstrual cycle is the regular natural change that occurs in the female reproductive system that makes pregnancy possible. 2) The follicular phase is a phase of the estrous cycle during which follicles in the ovary nature from primary to a fully mature grafian follicle.It ends with ovulation.3) The luteal phase begins during the second half of a menstrual cycle normally lasting around 12 14 days after the ovulation and it is responsible for producing progesterone.

A garden has a length of 1.5 x102 m and a width of 0.5 x 102 m. what is the area of the garden?

Answers

Answer:

7.5 × 10^3 m^2

Explanation:

The garden described in this question takes the shape of a rectangle, which has a length of 1.5 x102 m and width/breadth of 0.5 x 102 m.

To calculate the area, we use the formula for calculating the area of a rectangle, which is;

Area = length (L) × width (w)

Area = 1.5 x102 m × 0.5 x 102 m

Area = 150 × 50

Area = 7500

This, the area of the garden is 7500m^2 or 7.5 × 10^3 m^2

Suppose you take glycine tRNA and modify it so that the glycine is changed to valine. You then find that the amino acid sequence in the generated proteins does not show the expected change. This result would suggest that the protein synthesis machinery recognizes the _______ and is _______ with what was actually found by researchers.

Answers

Answer:

Suppose you take glycine tRNA and modify it so that the glycine is changed to valine. You then find that the amino acid sequence in the generated proteins does not show the expected change. This result would suggest that the protein synthesis machinery recognizes the tRNA anticodon and is congruent with what was actually found by researchers.

Explanation:

A group of researchers led by Seymour Benzer demonstrated that the anticodon of the charged tRNA was recognized by the protein synthesis machinery, when they changed the amino acid sequence. This example shows the exact result as found by the researchers.

Which term refers to all areas of Earth where life exists?
biosphere
biome
community
ecosystem

Answers

Biosphere! Your welcome:)

The term that used to represent the land, water, surface and atmosphere of the whole planet where life exists is called the biosphere. So option A is correct.

What is the biosphere?

Multiple species make a population, population makes a community, the community makes an ecosystem, ecosystem makes a biome, and biome makes a biosphere.

The biospheres can be classified as:

Lithosphere: It consists of the land part of the earth. The lithosphere comprises plains, plateaus, mountains, etc.

Hydrosphere: The water constituent of the earth forms the hydrosphere. It includes rivers, oceans, lakes, ponds, etc.

Atmosphere: The air surrounding the earth comprising of varying gases forms the atmosphere of the earth.

So biosphere is the largest unit of ecology which include the whole planet like earth in it. So option A is correct.

What process is similar in function to genetic engineering but different in the mechanism it uses? A. Replication in a bioreactor B. Cellular Respiration C. Breeding for specific traits D. Genetic Calculus

Answers

Option C. Breeding for specific traits is a similar process in function to genetic engineering but different in the mechanism it uses.

Genetic engineering refers to the process of using recombinant DNA methodologies to alter the genome of a particular organism and thus obtain the desired characteristics/traits in organisms derived from them.

An example of genetic engineering is the use of recombinant DNA methodologies to develop Escherichia coli strains that generate human insulin.

Moreover, selective breeding refers to the process aimed at developing organisms with desirable characteristics by choosing parents with these traits in order to cross them and produce offspring with these phenotypic traits.

For example, wheat plants with better yields can be obtained by crossing between wheat varieties that exhibit desired phenotypic traits.

In conclusion, Option C. Breeding for specific traits has a similar objective that genetic engineering but the mechanism to reach this objective is different.

Explanation:

   GMOs are food items that have been made using genetic engineering techniques. ...

   GMO foods are easier and less costly for farmers to grow, which makes them cheaper for the consumer. ...

   The main concerns around GMOs involve allergies, cancer, and environmental issues — all of which may affect the consumer.

The advantages include improved human health, increased food production, reduced environmental impact, and so on. There is a risk that new diseases originating in genetically engineered animals will be transmitted to non-genetically engineered animals, including humans.

What is genetic engineering?

Genetic engineering (also known as genetic modification) is a process that uses laboratory-based technologies to alter an organism's DNA makeup.

This could be as simple as changing a single base pair (A-T or C-G), deleting a region of DNA, or adding a new segment of DNA.

Gene therapy aims to modify genes in order to correct genetic flaws and thus prevent or cure genetic diseases. The goal of genetic engineering is to modify the genes in order to improve the organism's capabilities beyond what is normal.

The benefits include improved human health, increased food production, and reduced environmental impact, among other things. There's a chance that new diseases originating in genetically engineered animals will spread to non-genetically engineered animals, including humans.

Thus, these are some pros and cons of the genetically modified animals.

Proteins in the cell membrane have many functions. Which type of protein would be used for cell recognition and as a receptor? A. Pore proteins B. Endoplasmic proteins C. Glycoproteins D. Integral proteins

Answers

Answer:

C. glycoproteins

Explanation:

Glycoproteins are proteins containing glycans (oligosaccharide carbohydrates) attached to amino acid side chains. These oligosaccharides are attached to the amino acid chain by a posttranslational modification referred to as glycosylation, a modification generally found in extracellular regions. Glycosylation refers to the chemical reaction in which a glycosyl donor (i.e., the carbohydrate) is attached to a functional group in the protein. The glycosylation sites play distinct functional roles for both cell interactions and cell recognition. Moreover, glycosylation sites are also essential for substrate recognition by an enzyme. For example, secreted cytokines are glycosylated, which is required for their binding to receptors.
