Sex Linked Inheritance
Why are women often carriers of X-linked traits but rarely affected by them?
Answer:
See the answer below
Explanation:
Women are often carriers of X-linked traits but are rarely affected by the trait because they have two X chromosomes and the two have to carry the X-linked allele in order for them to be phenotypically affected, especially if the trait is a recessive one.
Unlike men that are XY and only require one X-linked allele in order to be affected for X-linked recessive traits, women need two alleles - one on each chromosome - in order to be affected. One of the X chromosomes of a woman usually comes from the woman's father and the other one from her mother. In order to be affected, a woman must inherit an affected chromosome from her father and her mother respectively, thereby reducing the probability of having the trait.
The X chromosome of a man usually comes from his mother. Hence, a man only needs to inherit an affected chromosome from his carrier mother to be affected for the trait, thereby increasing the probability of having the trait when compared to a woman.
This is not the case for X-linked dominant traits where both men and women have an equal chance of being affected.
Women carry two XX chromosomes in their cells. They carry the X chromosome but rarely gets affected by the trait because to be phenotypically affected they should carry X linked disease trait on both the X chromosomes.
Especially in the case when the trait is recessive then they should have two XX chromosomes which are linked to traits.
In the male, they have one X and one Y chromosome so they acquire an X chromosome and gets affected by it.
In male presence of one X chromosome from the carrier mother is enough to pass the trait. While in females to have X linked recessive trait they should have two alleles.
The woman does not get affected as one chromosome comes from the father and the other from the mother so to be affected the woman must acquire genes with traits from both parents.
Therefore, women are often carriers but are rarely affected by them.

what are the cells that divide to produce gametes ?
Answer:
cells needed for sexual reproduction
Explanation:
so that during fertilization,the total number of chromosomes will be 46..
What are the cells that divide to produce gametes? germ cells
What is a gamete?It is the reproductive cell of an organism. They are haploid in nature.
How many types of gametes are there?There is a male gamete that is termed sperm (animals) or pollen grain (plants) and a female gamete that is termed ovum (animals) or egg (plants).
What kind of division occurs prior to gamete formation?Meiosis, or reductional division, occurs prior to gamete formation.
What is its significance?It ensures that after fertilization, the normal diploid number is maintained.
What kinds of cells undergo this division to produce gametes?Germ cells are the cells that produce gametes.

how energy is recycled in an ecosystem. how our atmosphere maintains its temperature. the importance of decomposers in an ecosystem. the one-way flow of energy in an ecosystem.
Answer:
The flow of energy in ecosystems is unidirectional or one-way.
Explanation:
Energy is the ability to do work. Energy flows in one direction in an ecosystem and is not recycled. This is because during the transfer of energy from one level to another, energy is lost. Most of the energy received from the sun by producers, plants, is lost as heat to the surroundings. The rest energy is converted by plants to produce food in the form of chemical energy.
Primary consumers feed on plants and secondary consumers feed on the primary consumers and so on up to quaternary consumers. However, at each level of energy transfer, some energy is lost as heat during respiration, some as unused or undigested materials, while some others are used for each organisms metabolic activities. About 90% of energy in a trophic is used at that trophic level. Therefore, only about 10% as much energy is available to organisms at each successive trophic level. Therefore, energy is not recycled in ecosystems.
Earth's atmosphere maintains its temperature by means of the earth's energy balance. This refers to how incoming from the sun and outgoing energy from the earth are in balance, thereby keeping earth's temperature constant.
Decomposers, are organisms such as bacteria, fungi, and small animals such as ants and worms that eat and decompose dead and waste organic matter and which recycle nutrients back into food chains making them available for plants use. Therefore, decomposers are an essential components of all ecosystems.

Which of the following
is not a type of lipid?
A. Fat
B. Steroids
C. Sugar
D. Waxes
Pretty sure the answer is Sugar, Correct me if I'm wrong
Sugar is not a lipid, but it is a carbohydrate. Thus, option C is correct.
What is lipid?Lipid is type of biomolecule, consisting, fats, steroids, waxes, and fat soluble vitamins such as A, D, E, K and others. It is an organic molecule which is hydrophobic or amphiphilic molecule which is insoluble in the water.
Fatty acids are included in the class of carboxylic acids which has long hydrocarbon chain and terminal carboxyl group (COOH). As compare to other molecules found in food that are carbohydrates and proteins, lipids contain more than twice energy.
Lipids play significant role in cell signaling as lipid signaling, which is very vital part of it. It is also involved in immunity, hormones such testosterone, estrogen, cortisol. Fat soluble vitamins play an important role in nutrition.
Therefore, sugar is carbohydrate not lipid. Therefore, option C is correct.

During the bacterial transformation lab, what was the primary purpose of including Ampicillin in the agar
Answer:
allows for selection of E. coli mutants that successfully picked up the plasmid
Explanation:
Ampicillin is a penicilin type medicine or antibiotic that can treat the infections caused by bacteria.
In bacterial transformation lab, the ampicillin is added in the agar in order to select the E.coli mutants which picked the plasmid and have gained ampicillin resistance gene. Bu doing so, it causes the production of the enzymes that prevents the activity of the ampicillin as well as the bacteria survive. The ampicillin antibiotics present in the agar kills the bacteria without having the ampicillin resistance gene.

One line with red flowers and the other line with violet flowers. You carry out a monohybrid cross and find that all of the F1 offspring have violet flowers, while 97 of 400 F2 offspring have red flowers.
Explain the inheritance of flower colour in this plant species.
Answer:
See the answer below
Explanation:
The inheritance of flower color in the plant species follows the simple dominance/recessive inheritance of Mendel. The red flower trait did not show up at all at F1 only for it to show up at F2. It simply means that the red flower trait is recessive while the violet flower color is dominant.
Assuming that the allele for violet flower color is designated as R while that of red flower color is designated as r. The genotype of the violet flower would be true-breeding, RR, while that of red flower color would also be true-breeding rr:
RR x rr
F1 Rr Rr Rr Rr
phenotype ratio = all violet flower color
Rr x Rr
F2 RR Rr Rr rr
phenotype ratio = 3/4 violet flower color and 1/4 red flower color
97 red flower offspring out of 400 is approximately 1/4.
Hence, the inheritance of flower color in the plant obeys a simple dominant/recessive Mendelian law with the violet color trait dominant over the red color trait.

Under what conditions is it ethical for conservationists who live in the United States to lobby government officials in Brazil, Indonesia, and other tropical countries to slow the rate of loss of old-growth forest
The correct answer to this open question is the following.
I can say that under the following conditions it is ethical for conservationists who live in the United States to lobby government officials in Brazil, Indonesia, and other tropical countries to slow the rate of loss of old-growth forests.
First, American conservationists have to use diplomatic approaches to use the correct language to ag¿ddress the issue and the political leaders of those countries.
Then, they have to fully understand what the situation is, knowing all sides of the story so they can avoid any mistakes. They have to include the official version of the governments to try to not bias their opinions.
Once they have done that, then they will have all the elements to make an official statement about the critical situation in those above-mentioned places.
And one very important thing, they have to be careful in using polite words such as "invite" or "exhort" when addressing the federal institutions of those countries.
