Answer:
A man with hemophilia (a recessive, sex-linked condition) has a daughter of normal phenotype.
Explanation:
Hemophilia A is the most common inherited coagulation disorder, and it occurs due to the lack or decrease in the activity of coagulation factor VIII. Disorder in the synthesis of coagulation factors occurs due to a mutation in the structural gene on the X chromosome. It occurs mainly in men and is characterized by a lifelong tendency to bleed.

Answer:
kangaroo
Explanation:
The evolution of new organs usually builds on preexisting structures that are modified in form and sometimes function. The embryos of fish, amphibians, reptiles, birds, and mammals all have pharyngeal pouches or gill slits. These pouches develop into gills in adult fish and they are used to absorb oxygen from their watery environment. These same pouches become parts of the in_________ humans.
a) eyes and lungs
b) ear and throat
c) eyes and nose
d) lungs and heart
Answer:
lungs and heart
Explanation:
lungs and heart is the answer because human lungs is use for gas exchange during respiration or while you breathe. When humans breathe, the lungs absorb oxygen from the inhaled sir into the blood and carbondioxide leaves the blood when we breathe out. The heart pumps the blood, and oxygenated blood are carried in the blood when air is inhaled and carbondioxide leaves the blood when you exhale. The blood carries nutrients and oxygenated blood. Therefore, lungs and heart work hand in hand in absorbtion of oxygen from it's environment.

circulatory system summary
Answer:
The circulatory system or vascular system is an organ system that helps in the transport of the blood from and to the heart. The blood transport also takes oxygen, nutrients, hormones, and other components from the heart to the various part of the brain with the help of the arteries and carry waste such as carbon dioxide to the heart in veins.
The oxygenated blood enters in the left atrium and moves to the left ventricle to the aorta and starts its journey to the body whereas deoxygenated blood enters in the right upper chamber or right atrium of the heart and pump to the right lower chamber and to the lungs to carry the oxygen again. This process is a continuous process.
The Chatham Island robin is a small endangered bird found in scrub forests off the coast of New Zealand. The robin is preyed upon by introduced species such as cats and rats. In 1980, the population decreased to only 5 individuals and every individual today is a descendant of a single female. Which of the following is best illustrated in the decline of the Chatham Island robins?
1. Carrying capacity
2. Population bottleneck
3, Population overshoot
4. Type I survivorship
Answer: 2. Population bottleneck
Explanation:
A Population bottleneck is a term used to refer to an event that causes the population of a species to reduce in very large numbers. Such an event can be environmental disasters like famine, the overhunting of a species or the destruction of its habitat.
In the case of the Cha-tham Island Robin, the bottleneck event must have been the introduction of cats and rats which then went on to hunt the birds to near extinction.

True breeding plant round seeds (DD) were bred with true breeding smooth
seeds(dd) to produce F1 offspring. F1 offspring were then bred with other F1
offspring. What is the genotypic ratio of the resulting F2 offspring? What is the
phenotypic ratio of the resulting F2 offspring?
Answer:
Genotypic ratio F2 = 1:2:1
Phenotypic ratio F2 = 3:1
Explanation:
In this case, parental genotypes can produce only one type of gamete, i.e., one parent can produce only D gametes, while the other parent can produce only d gametes. Therefore, all F1 generation will be heterozygous (Aa). An F1 hybrid is the first filial generation of offspring obtained from crossing between different parent types. The F1 will produce two gametes (A; a) in a ratio 1:1, thereby the F2 obtained by crossing F1 offspring will have a phenotypic ratio of 3:1 (3 D_; 1 dd) and a genotypic ratio of 1:2:1 (1 AA; 2 Aa; 1 aa).

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.

Dihydromyricetin (DHM), a chemical found in the moyeam plant of Asia, has shown the ability to treat certain
cancers.
Which of the following answer choices best describes a possible mechanism of action for this cancer drug?
Choose 1 answer:
А
DHM decreases apoptosis in cancer cells.
DHM decreases apoptosis in normal cells.
DHM promotes apoptosis in cancer cells.
D
DHM promotes apoptosis in normal cells.
Answer:
(C) DHM promotes apoptosis in cancer cells.
Explanation:
Since some cancers are caused by a lack of apoptosis (programmed cell death), DHM treats cancer by forcing apoptosis to occur in cancer cells, stopping their growth and division.
The choice which best describes a possible mechanism of action for this cancer drug is DHM promotes apoptosis in cancer cells. The correct option is C.
What is Dihydromyricetin (DHM)?DHM is a chemical that is present in the plant, Hovenia Dulcis grow in Japan. It is a raisin plant and has several medicinal values. It is used in East Asia as a hangover medicine.
Apoptosis is a process of cell death, so if DHM promotes apoptosis in the cancerous cells, then it will reduce cancer by killing the cancer cells.
Thus, the correct option is C, DHM promotes apoptosis in cancer cells.

How does the amount and type of fuel impact the distance a spacecraft can travel?
A space ship's momentum will continue to carry it forward indefinitely at a constant speed after the engines are turned off.
What do you mean by momentum?Momentum in a simple way is a quantity of motion. Here quantity is measurable because if an object is moving and has mass, then it has momentum. If an object does not move then it has no momentum.
Momentum, finance, refers to the capacity for a price trend to sustain itself going forward. Strong momentum can continue in an upward or downward trend, which can be confirmed by changes in trading volume and other technical indicators.
Momentum is how we measure mass that is in motion. Any moving object will have momentum. Under the law of physics, the object's momentum equals mass times velocity. Momentum is affected by the parameters' mass as well as velocity.
