Which description is correct for both oogenesis and spermatogenesis?
The cells have 46 chromosomes until meiosis II is completed.
After meiosis I, the cells have 23 chromosomes.
Part of meiosis I is completed before birth.
The entire process takes about 70 days.
Answer:
After Meiosis I, the cells have 23 chromosomes
Explanation:
It is B
In meiosis there is a reductive phase (meiosis I) and the not reductive phase (meiosis II). Option B). After meiosis I, the cells have 23 chromosomes.
What is meiosis?Meiosis is a process by which, from a diploid germ cell (2n), four haploid cells (n) -the gametes, sperm and egg cells- are produced. This is the gametogenesis process.
Each daughter cell has half of the chromosomes of the original one.
There are two phases in meiosis:
the first one in which occurs a chromosome's reduction division, and the second one where the cell suffers a new division, but this one is not a reductive one.So, if the germ cell has 46 chromosomes, after meiosis I each new cell will have 23 chromosomes, because meiosis I is the reductive phase.
Option B is correct.

∠A and \angle ∠B are supplementary angles. If m\angle A=(3x-23)^{\circ}∠A=(3x−23)
∘
and m\angle B=(2x-12)
∘
, then find the measure of \angle ∠B.
Answer:
[tex]B = 74[/tex]
Explanation:
Given
[tex]A=(3x-23)[/tex]
[tex]B=(2x-12)[/tex]
Required
Find B
Since A and B are supplementary, then:
[tex]A + B = 180[/tex]
Substitute values for A and B
[tex]3x - 23 + 2x - 12 = 180[/tex]
Collect Like Terms
[tex]3x + 2x = 180 + 23 + 12[/tex]
[tex]5x = 215[/tex]
Divide through by 5
[tex]\frac{5x = 215}{5}[/tex]
[tex]x = 43[/tex]
Substitute 43 for x in [tex]B=(2x-12)[/tex]
[tex]B = 2*43 - 12[/tex]

Answer:
Biotic: Fish, Plants, Animals, Some bacteria in the water
Abiotic: Water, Sunlight, Rocks
Changes to any ecosystem can affect the way organisms live. It can be a big change like having to adapt to their surroundings. An example is being camouflaged, or having an increase in population. Bad changes can lead to population decline, or maybe even being extinct.

What is the phenotype(s) you can expect from crossing a pure round parent and a
pure wrinkled parent?
R=round
r=wrinkled
Answer:
Round
Explanation:
Round is the dominant phenotype and wrinkled is the recessive one. When crossing, the offspring will have one allele from each parent, i.e. Rr, wrinkled phenotype will hence be masked by the dominant round one.

In DNA, different alleles of a gene have a different sequence of ___________________. Alleles may have a different sequence of ___________________ in RNA that result in a different sequence of _________________ in a protein. Therefore, proteins produced from different alleles of a gene may have different structures and functions and result in different characteristics.
Answer:
blood cotton dna
Explanation:
hahahahahaahahahaha
In DNA, different alleles of a gene have a different sequence of nucleotides. Alleles may have a different sequence of nucleotides in RNA that result in a different sequence of amino acids in a protein. Therefore, proteins produced from different alleles of a gene may have different structures and functions and result in different characteristics.
What are nucleotide?Nucleotides are the building blocks of DNA and RNA. They are composed of a sugar, a phosphate group, and a nitrogenous base. There are four types of nitrogenous bases in DNA: adenine (A), cytosine (C), guanine (G), and thymine (T). In RNA, the base thymine is replaced by uracil (U). The sequence of nucleotides in DNA or RNA determines the sequence of amino acids in a protein. Proteins are made up of long chains of amino acids, and the sequence of these amino acids determines the protein's three-dimensional structure and function.
Alleles are different versions of a gene. They can result from mutations or changes in the DNA sequence. Different alleles of a gene can produce proteins with different structures and functions, which can result in different characteristics in an organism. For example, the gene that determines eye color has several different alleles, which can result in different eye colors in people.
