What is the genotype of the male circled in pink?
Answer:XaY
Explanation
XAY is the genotype of the male circled in pink.
What is the genotype?An organism's genotype is made up of all of its genetic components. The alleles or variations that an individual carries in a specific gene or genetic region are also referred to as the genotype.
The term “genotype” broadly refers to an organism's genetic make-up; in other words, it characterises an organism's whole gene pool. The phrase can also be used to describe the alleles, or different forms of a gene, that an organism carries in a more specific meaning.
The genotype XAY for a male denotes the manifestation of an X-linked dominant characteristic. It is an X-linked dominant illness called fragile X syndrome. If their father has the condition, the sickness will afflict the girls, but not the males.
Therefore, The pink circled male's genotype is XAY.

What is the difference between native and nonnative species
Answer:
Native plants are those plants which occur naturally in a region. A non-native is one that does not.
Explanation:
For example, soybeans, kiwi fruit, wheat, honey bees, and all livestock except the American bison and the turkey are non-native species to North America.
Answer:
Native species are naturally present in an area. ... Non-native species do not cause environmental or economic harm. An important, not-to-be-missed distinction between non-native species and invasive species is that non-native species do not disrupt the natural functions and processes of our native ecosystems.

The diagram below shows a magnified view of a cross section of a plant root tip. Four parts of the root and the process that each performs are shown. Which process is directly responsible for root growth in plants?
a. storage
b. absorption
c. transportation
d. cell division
Answer:part c transportation
Explanation:
The process directly responsible for root growth in plants is cell division. So, the correct option is D.
What is Cell division?The process by which a cell divides into two or more daughter cells is called cell division. In relation to the above question, cell division is the mechanism due to which plant roots grow.
The meristematic region, which is in charge of cell division, is designated as part D in a cross-section illustration of the root tip of a plant. The meristem of the root is a unique region where cells continuously divide and differentiate into different tissues, helping the root to expand and mature.
Many tissues of the root, including the epidermis, cortex, and vascular tissue, are composed of distinct types of cells that differentiate when they divide into specialized cell types.
So, the correct option is D.

The gluten-free diet was originally intended for people with celiac disease, but it’s now become a new fad diet for the general population. Many people state that gluten-free diets are beneficial for people who aren’t sensitive to gluten, while others suggest that there’s no benefit. Use credible resources to evaluate the argument yourself. Do you think there’s sufficient scientific evidence to support the use of a gluten-free diet in people who aren’t sensitive to gluten? Provide evidence that supports your argument.
Answer:
The gluten free diet is helpful for the people that are sensitive to food with gluten it which occurs due to the celiac disease. It was originally meant for the such people but it becomes a new fad. However, there is no compelling evidence to support that gluten free diet helps in health improvements n non sensitive people.
In other hand there are majority of doctors are against the use of gluten free diet is not good for various body organs like heart. A study concluded that there are lower risk of heart disease in people take more gluten. Doctors and various study suggests that people with no celiac disease should not avoid gluten.
Answer:
There’s no benefit to a gluten-free diet for people who aren’t sensitive to gluten. Many websites state benefits of a gluten-free diet. These benefits range from weight loss to improved heart health. None of these sites backed up their claims with scientific research. More credible sites consistently state that there’s no scientific research to back up these claims. Right now, there’s no evidence that supports the benefits of a gluten-free diet in people who aren’t sensitive to gluten.

It moves the pollen to the ovaries.
It catches pollen.
It produces pollen.
Answer:
D
Explanation:
I did the assignment
The main function of the structure labeled A is it produces pollen. Therefore, the correct option is D.
What is a pollen?Pollen is a microscopic, powdery substance produced by the male reproductive organs of seed plants. It is made up of cells that contain the male gametes (reproductive cells) and is responsible for fertilizing the female reproductive cells (ovules) to produce seeds.
Pollen is often carried from one plant to another by wind, insects, or other animals, where it can then come into contact with the female reproductive organs of a different plant.
If the pollen comes into contact with a receptive ovule, it can fertilize the ovule and produce a seed. Therefore, the correct option is D.

Imagine you are introducing the Lac operon and the Trp operon to students who have never learned about it before.
Complete the table to compare the similarities and differences between the two operons.
Type of operon:
Trp operon is a repressible operon
Lac operon is an inducible operon.
Environment:
Trp operon is deactivated when tryptophan is present in the environment.
Lac operon is activated when lactose is present in the environment.
Repressor protein:
Trp operon is activated by tryptophan through bonding to the repressor protein
Lac operon is inactivated by lactose through binding to the repressor protein.
Transcription:
Trp operon -Tryptophan binds to the repressor protein, activating it, thus preventing active transcription of Trp operon.
Lac operon - Lactose binds to the repressor protein, deactivating it, thus allowing for active transcription of Lac operon.
An operon is a unit of DNA found in prokaryotes, containing a cluster of genes under the control of a single promoter and which performs a specific function. Examples of operons are the tryptophan (Trp) and lactose (Lac) operons.
Trp operon is responsible for tryptophan synthesis while Lac operon is responsible for lactose transportation and metabolism.

Genetic drift and natural selection can both be mechanisms of evolution. However, they are very different mechanisms. Explain how genetic drift is different from natural selectio
Answer:
Explanation:
Natural selection is the survival of individual organism due to the difference in phenotype. It serves as a basic for evolution as the different heritable characteristics in an individual is due to natural selection. Natural selection acts on the phenotype of the individual which is the visual observance while Genetic drift is the change in frequency of an allele that already exist in a population. This could lead to the allele being selected against and if very small can be lost with time.

a student placed a stack of rocks on a ramp. she added clumps of soil rooted with live grass. using a garden hose, she then applied a steady spray of water that soaked into the soil, making it heavier. what does the students experiment model
Answer: its C
Explanation:
Since a steady spray of water soaked into the soil, making it heavier. This student's experiment models: C. The role of rainfall in mass wasting.
A rock can be defined as a solid naturally occurring landform and it is typically made up of various minerals.
In this experiment, a stack of rocks was placed on a ramp and clumps of soil rooted with live grass were added. By using a garden hose, the student then applied a steady spray of water which soaked into the soil and made it heavier in weight.
Hence, this experiment models the role rainfall (steady spray of water) plays in mass wasting.
Mass wasting is also referred to as mass movement or slope movement and it can be defined as a geomorphic process through which rock, debris, soil, and regolith are largely moved downward, especially due to the force of gravity.
Basically, mass wasting describes the downslope (downhill) movement of rock and soil due to a steep slope and force of gravity.
In conclusion, the steady spray of water acts as a force which moves some of the soil constituents downward, making it heavier.
