a. one
b. haploid
c. RNA
d. diploid
Answer:
In sexually reproducing organisms, the number of chromosomes in the body (somatic) cells typically is diploid (2n; a pair of each chromosome), twice the haploid (1n) number found in the sex cells, or gametes. The haploid number is produced during meiosis.

Which one of these is not a human effect on the water cycle?
Developed areas prevent soil from absorbing rainwater
Precipitation is increasing in deserts due to an increase in water use
Air pollutants also wash back into the land and water bodies from precipitation
Storm water runoff carries pollution
Answer:
Precipitation is increasing in deserts due to an increase in water use
Explanation:
Just see for yourself
The one that is not a human effect on the water cycle is precipitation is increasing in deserts due to an increase in water use. The correct option is B.
What is the water cycle?The continual movement of water on, above, and below the Earth's surface is referred to as the water cycle, also known as the hydrologic cycle or the hydrological cycle.
One of the most essential elements of human life is water. There is water all over. It passes through your house as well as rivers, mountains, lakes, and oceans. Without water, neither humans nor any other species could survive.
In the majority of deserts, the air's moisture content is very low. In the dry air, light raindrops frequently evaporate before they can reach the ground. Rainstorms can occasionally appear as ferocious cloudbursts.
Therefore, the correct option is B. Precipitation is increasing in deserts due to an increase in water use.

Which part of a plant is the least complex
Answer:
Cells are the least complex part of a plant :>
Explanation:
When water evaporates from plants through leaves, it diffuses through tiny openings called stomatal pores. If the water vapor needs to diffuse a distance L through one pore to exit the leaf in a time t, what is the time needed for water vapor from the same leaf to diffuse through another pore of length 1.30 L
Answer:
L means same time.
Explanation:
Same time is needed for water vapor from the same leaf to diffuse through another pore of length 1.30 L because the evaporation takes place at the same time in the pore and water is evaporated to the atmosphere but more water is evaporated due to increase of surface area as compared to the other pore that have small opening so the time is same but the amount of water evaporated is different.

What was a conclusion that Mendel drew from the F2 generation of this cross?
A.
Three fourths of the F2 plants show the round seed phenotype and carry the dominant allele for roundness.
Answer:
option A
Explanation:
option A is the correct answer of this question .
plz mark my answer as brainlist plzzzz vote me also.
hope this will be helpful to you.
three fourth of f2 plant showed round seed phenotype and carry dominant allele for round ness character.
what is dominant character ?
allele can be defined as a form of a gene which can be present as a pair shows either homozygous or heterozygous phenotype of a character.
these gene can express the phenotype either dominant or recessive form. In a cross between two organism, in F2 generation the offspring's are produced shows three phenotypes homozygous dominant, recessive, heterozygous dominant.
dominant allele can suppress recessive allele.

A. Are each associated with a particular sound
B. Can be used in a variety of languages
C. Each have an uppercase and a lowercase form
D. Spell out different instructions depending on their order
Answer: The answer is D.
Explanation: It makes the most sense and explains how both the aplhebet and DNA have simrialities.
The building blocks of DNA are like alphabet letters because they spell out different instructions depending on their order. Thus, the correct option for this question is D.
What are the building blocks of DNA?The building blocks of DNA are known as nucleotides. These nucleotides are made up of three parts. They are as follows:
A phosphate group.A pentose sugar.Nitrogenous base.These nucleotides are arranged by one another with the help of a linkage known as phosphodiester linkage. Nitrogenous base in nucleic acids like DNA includes Adenine, Thymine, Cytosine, and Guanine. In the DNA, they are represented as A, T, C, and G. Due to this, the building blocks of DNA are like alphabet letters.
Therefore, the building blocks of DNA are like alphabet letters because they spell out different instructions depending on their order. Thus, the correct option for this question is D.

8. Genes are sorted and recombined to produce gametes. Which statement describes a possible result of this process?
A. Gametes always form with genetic material identical to the parent
B.Gametes are formed with the same number of chromosomes as the parent cells
C.Offspring display half of their traits from their mother and half of their traits from their father
D.Offspring have traits not displayed by either parent
Answer:
c option is correct.
Explanation:
gametes are produced by meiosis during which genes get crossed in a process of crossing over ad new recombinent characters are produces. these gametes fertilized and offsprigs have multiple characters they get from their mother and faaher. so offsprimgs have characters half from mother and other half from father.
Genes often produce gametes. The statement that describes a possible result of this process is that Offspring display half of their traits from their mother and half of their traits from their father.
What is genes and gametes?A gene is known to be the molecular unit of heredity of all living beings.
A gamete is known to be a cell that comes together with another cell during fertilization that takes place in organisms that reproduce and this is a product of the male and the female gamete.

Differentiate between cell mass and cell number
Answer:
Measurement (Count) of Cell Numbers:
1. Breed Method:
A known volume of microbial cell suspension (0.01 ml) is spread uniformly over a glass slide covering a specific area (1 sq. cm). The smear is then fixed by heating, stained, examined under oil immersion lens, and the cells are counted.
Customarily, cells in a few microscopic fields are counted because it is not possible to scan the entire area of smear. The counting of total number of cells is determined by calculating the total number of microscopic fields per one square cm. area of the smear.
Answer:
cell mass: The total mass of all the cellular elements in the body which constitute all the metabolically active tissue of the body
Cell number: The sequence of numbers or characters, that when dialed, connects to a particular cellular telephone

Answer:
It helped her fight off the stop protein, eventually helping her create more amino acids.
The stem cell therapy helped lucy break down deoxyadenosine as it helped her fight off the stop protein, eventually helping her create more amino acids.
What is amino acid?Amino acid has the organic compound containing both an amino[tex](-NH2)[/tex] and a carboxylic acid [tex](-COOH)[/tex] functional group. The component of amino acid not contained in starch is that amino acids contain nitrogen but not starch.
On the other hand, starch has a carbohydrate molecule made up of monomers called monosaccharides. The monosaccharide is a long chain of carbon, hydrogen and oxygen atoms. This suggests that the major structural difference between amino acids and starch has that amino acids contain nitrogen but not starch.
There are several types of protein such as structural protein, transport proteins, antibodies, contractile proteins, hormonal proteins, and enzymes.
