How are the alleles for sex-linked traits inherited? They are passed from the Y chromosome in parents to the X chromosome in offspring. They are passed from the X chromosome in parents to the XY chromosome in offspring. They are passed from parents to offspring on the X and Y chromosomes. They are passed from any chromosome in the parents to the X or Y chromosome in the offspring.

Answers

Answer 1

Answer:

Alleles for sex-linked traits are inherited in such a way that they are passed from parents to offspring on the X and Y chromosomes.

Generally, sex-linked traits are traits or genes that are found on the sex chromosomes only. In humans, females have XX sex chromosomes while males have XY sex chromosomes.

Thus, X-linked traits are passed from parents to offspring via the X chromosomes only. Since both males and females have X chromosomes, it means both genders can have X-linked traits.

Y-linked traits are passed from parents to offspring via the Y chromosomes only. Since only males have Y-chromosomes, it means that only the male gender can have Y-linked traits.

How and why do cells reproduce

Answers

Cells reproduce for 3 reasons

-Repair
-Growth
- And to make new kinds of cells

And how they reproduce

Scientists call the process of somatic cell division mitosis. Mitosis has six distinct steps in which the cell organizes and copies the DNA in the nucleus. Once copied, each new cell has its own copy of the DNA. The six steps of mitosis are prophase, prometaphase, metaphase, anaphase, telophase and cytokinesis. Some authorities consider the non-dividing portion of the cell’s lifecycle, known as interphase, to be one of seven steps involved in mitosis; however, interphase cells are not actively dividing. Sex cells, such as sperm or eggs, must divide differently. Sex cells only possess one-half of the DNA that makes up a new animal. That way, when they combine, the resulting organism gets half of its DNA from its mother and half from its father. Because sex cells only want half of the DNA in each cell, they go through a different division process called meiosis. In meiosis, the cells split a second time, which yields four daughter cells rather than two as with mitosis; however, this provides each daughter cell with 23 chromosomes in contrast to the 46 chromosomes in somatic cells.

H2O has a mc021-1.jpgHvap = 40.7 kJ/mol. Solve for the quantity of heat released when 27.9 g of H2O condenses.A) 60.00 kJ
B) 61.05 kJ
C) 63.09 kJ
D) 68.60 kJ

Answers

The heat released for a certain mass of water that is condensing is calculated by multiplying the heat of vaporization and the amount of the substance. Calculation is as follows:

Heat released = (40.7 kJ/mol) (27.9 g) ( 1 mol / 18 g) = 63.09 kJ

Therefore, the correct answer from the choices listed above is option C.

Give the function of all of the following parts of a typical flower. a. Petalsb. Stamen c. Pistil
d. Ovule
Please help.

Answers

Answer:

The petals of a flower are usually brightly colored to attract pollinators such as bees, butterflies and hummingbirds. The stamen is the small body that holds and produces pollen. The pistil is the ovary of the flower. Ovules are the egg cells of a flower, which eventually become seeds.

How can mutations affect evolutionary processes? A) Mutations are novel genes that increase an organism’s fitness in the environment. B) Mutations are new genotypes that cause an organism to be more poorly fit due to non-functional essential genes within its genome. C) Mutations are changes in the genome that can code for new phenotypes that may be selected for or against by the environmental pressures. D) Mutations are changes to protein structure that create new genotypes that can be selected for or against by the environmental pressures.

Answers

Answer:

Option C

Explanation:

Option A is incorrect as mutations may be detrimental to the organism and are not always beneficial. Option B is incorrect as there are instances where mutations may enable organisms to be better adapted to the environment. Option D is incorrect as genotypes are not selected for or selected against by environmental pressures, it is only the phenotype (exhibitable/ visible traits) that can be selected for or against, hence option C is the answer.

A man goes swimming in a pond. As he swims, which reaction provides energy to power his muscles?ATP regenerates from ADP using energy in glucose.
The ADP molecule adds a phosphate group and produces ATP.
ATP loses one phosphate group and converts to ADP.
NextReset

Answers

The answer is ATP loses one phosphate group and converts to ADP.

ATP stores potential energy in the form of chemical bond. By breaking this bond and removing one phosphate group from ATP, which is then converted to ADP, great amount of energy is released and it is ready to be used.
