Chromosome pair 23 are the sex chromosomes and are responsible for determining the gender of a human. The large chromosome is an X chromosome, and the small chromosome is the Y chromosome. If there are two X’s, then the individual is a female. If there is an X and Y, then the individual is a male.
Answers
Answer:
This is true.
Explanation:
More commonly, an X chromosome will die and get replaced by a Y chromosome (all humans start off as females). When this occurs, the substitute Y chromosome causes changes in the zygote to occur; they begin developing male genitalia (i.e. penises, testicles, prostates, etc.).

What caused the chromosomal alteration in the number 21 chromosomes? (LS3.2) A. Part of one chromosome attached to another chromosome B. Some of the genes on a chromosome were reversed C. A duplicated chromosome failed to separate during meiosis D. A part of a chromosome was lost
Answers
Answer:
The correct answr is - A. Part of one chromosome attached to another chromosome.
Explanation:
Translocation is one of the chromosome abnormality that cause change in the number of the chromosome. In the translocation a part of the chromosome breaks off and bind or attached to the another chromosome.
The translocation cause various disorderes in individual one of them is Down syndrome which is the result of the alteration of chromosome number 21. In this translocation or specicifically the chromosome portion of chroromosme 14 breaks off and reattaches to the chromosome 21 result in one normal 14 and two normal 21 chromosme so there is trisomy occurs.
Answer:
A duplicated chromosome failed to separate (nondisjunction)
Explanation:
If nondisjunction occurs during meiosis I, homologous chromosomes fail to separate. This produces abnormal gametes that contain two members of the affected chromosome or none. This is why there is an extra chromosome in the 21 chromosomes.
What is a likely reason for the change from mitosis to meiosis during reproduction under these conditions?
Answers
Mitosis and meiosis are the two types of cell division, which result in the generation of daughter cells. Yeasts are capable of undergoing meiotic and mitotic division under favorable conditions.
The correct answer is:
Option B: Crossing over genes during meiosis increases diversity and the chance of survival of the next generation.
The significance of meiosis can be explained as:
Meiosis is a reduction division, in which the diploid parent cell gives rise to haploid daughter cells.The crossing over of the genetic material of the haploid cells leads to genetic diversity and a higher rate of survival.Meiosis leads to genetic diversity as the data in the parent cells are fused and recombined to give rise to new offspring.Thus, meiosis is an important step in the genetic variation and survival of the organism.
Therefore, option B is correct.

6. an example of how Kahlo influenced artists who came after her
Explanation:
Frida Kahlo was a Mexican painter. She was born in Coyoacan, which at that time was a small bus stop on the outskirts of Mexico City. Her father was a painter and photographer of German-Jewish origin.
Kahlo began painting after a serious traffic accident in 1925. Her lifelong pain after the accident was the subject of many of her images. In addition to personal experiences, she also describes how hard life women lived. She was also influenced by the culture of the Mexican indigenous people, and portrayed them in bright colors, with a mixture of realism and symbolism.

If a plant cell needs energy for endocytosis, what does it use and where does the energy come from?
Answers
Explanation:
Active transport uses energy stored in ATP to fuel the transport. ... Endocytosis methods require the direct use of ATP to fuel the transport of large particles such as macromolecules.
Hope this helps!
If a plant cell needs energy for endocytosis, its use and energy come from- Active transport from ATP.
Endocytosis is an energy-using process by which cells internalize molecules by engulfing them.
Endocytosis needs to use directly ATP to fuel the transport of large particles such as macromolecules, parts of cells that can be engulfed by other cells in a process called phagocytosis.Active transport is the movement of molecules across a cell membrane in the direction against their concentration gradient, i.e., moving from a low concentration to a high concentration and this uses cellular energy.Thus, If a plant cell needs energy for endocytosis, its use and energy come from- Active transport from ATP.

What are the genotypic and phenotypic distributions for the F1 and F2 generations from a cross between a chick with black (BB) feathers and chicken with white (WW) feathers if the color is determined by alleles that show codominance. The heterozygote is an erminette chicken, which is black and white speckled.
Answers
Answer:
Please find the punnet square to this question as an attachment
F1 generation:
genotype = BW
Phenotype = Erminette offsprings
F2 generation:
genotype = BB (1): BW(2): WW(1)
Phenotype = 1 Black, 2 Erminette, 1White
Explanation:
This question involves a gene coding for feather color in chickens. The allele for black feathers (B) is codominant with the allele for white feathers (W) to form an erminette chicken (black and white speckles).
According to this question, a cross between a chick with black (BB) feathers and chicken with white (WW) feathers will result in an all erminette chicken (BW) in the F1 generation (see attached image)
Also, in the F2 generation got by self-crossing the Erminette genotype in the F1 generation (BW), the following genotypic and phenotypic ratios are observed:
Genotypic ratio = BB (1): BW(2): WW(1)
Phenotypic ratio = 1 Black, 2 Erminette, 1White

Answers
Answer:

Explanation:
because you having digestive have nothing to do with your oxygen and breathing
Problems with the digestive system make it very difficult for the body to digest enough food, and it is harder to exercise with digestion problems like this because cells would not work as well because they would not have enough glucose molecules, which is the last option.
What is the function of the digestive system during exercise?
Exercise is important for the body, and the digestive system plays an important role in it because the digestive system breaks down the food, and then the simplified food enters the blood and is then taken up by the cells for the different activities. If there are any issues with the digestive system, the food will not be well absorbed into the cells, and no energy will be produced for the exercise.
Hence, the answer is that cells would not work as well because, even though they would have enough oxygen molecules from the air, they would not have enough glucose molecules from food. The last one is the true fact.
