Explanation:
what is the identity the genotypes of the aunt and her fiancé?
Genotypes are what is in people's genes not what you can see on the outside.
During meiosis, homologous chromosomes exchange genetic material. This exchange of genetic material
The answer is; crossing over/synapsis
This occurs when the arms of homologous non-sister chromosome pairs connect at points called chiasma. They exchange genetic material causing recombination. This mostly occurs in the later stages of prophase I into metaphase I of meiosis. Flaws in crossing over can cause genetic diseases in offspring.
During meiosis, homologous chromosomes undergo an exchange of genetic material, known as recombination or crossover. This process contributes to genetic variation as maternal and paternal alleles are combined onto the same chromosome. Errors in meiosis can result in genetic disorders like Down syndrome.
Explanation:During the process of meiosis, homologous chromosomes undergo an exchange of genetic material, a process known as recombination or crossover. Starting in meiosis I, homologous chromosomes pair up and exchange non-sister chromatid segments, which leads to a unique genetic composition. This exchange significantly contributes to the diversity of genetic combinations in the resulting haploid gamete cells.
As the chromosomes align, particular segments of genetic material are exchanged, while the gene order remains unchanged. The result of this recombination is that maternal and paternal alleles combine on the same chromosome, causing extensive shuffling of alleles. These crossover events serve as an essential source of genetic variation.
If there are errors in meiosis, such as incorrect chromosome segregation, genetic disorders like Down syndrome can occur. These crossover events are fundamental in producing genetic variation, leading to a diverse gene pool and enhanced adaptability for species.

How do plants store energy from photosynthesis?
Photosynthesis is the process plants and some algae use to convert light energy to chemical energy stored as sugar within chloroplasts -- the energy factories found in plant cells. Plants need only carbon dioxide and water for photosynthesis to work.
Answer:
The correct answer is "in the form of starch".
Explanation:
Plants store energy from photosynthesis in the form of starch. Starch is a polysaccharide, made from several units of glucose linked together following a particular disposition. The glucose that is produced during photosynthesis is used to synthesize starch, biomolecule that is used as a form to store energy.
Which stage of the cell cycle involves the division of the cell’s nucleus?
Metaphase
At the end of the phase the cell divides into two new cells
The division of the cell's nucleus occurs during the mitotic phase of the cell cycle, specifically in the process known as mitosis, which is followed by cytokinesis resulting in two daughter cells.
The stage of the cell cycle that involves the division of the cell's nucleus is called the mitotic phase, which is more specifically known as mitosis. The cell cycle is primarily divided into two major phases: interphase and the mitotic phase. During interphase, the cell undergoes growth and DNA replication. This phase allows the cell to prepare for division, leading up to the mitotic phase. Mitosis then follows interphase and is the process by which the replicated chromosomes are segregated and distributed into two daughter nuclei. The mitotic phase can be further divided into several steps including prometaphase, metaphase, anaphase, and telophase. After mitosis, the cell typically goes through cytokinesis, a process dividing the cytoplasm, resulting in two daughter cells.

Which structure, if cut off, will hamper sexual reproduction in fungi? A. hyphae B. fruiting body C. rhizoids D. mycorrhizae
Answer:
B. fruiting body
Explanation:
Fruiting body is the term used for the part of fungi that produce spores that take part in the sexual reproduction of fungi.
As you can see in picture, it is very prominent part of fungal body that where spores are formed as a result of sexual reproduction or fusion of gametes. These spores disperse from one place to another and upon landing on a suitable substrate, they give rise to the whole fungus body.
Mushroom is the most common example of fungus with a prominent fruiting body. Now the question is how the fruiting body is formed, they are produced from small thread like structures called hyphae that make most of the fungus body and are collectively termed as mycelium. They grow above the soil layer and develop new structures called gills,cap and stalk. In gills of the fruiting body, spored are formed.
Therefore, f one hyphae is cut off it will not hamper the sexual reproduction because fungus contains million of hyphae called mycelum that form fruiting body where sexual reproduction occurs. However, if fruiting body is cut, it wiil hamper the formation of spores and sexual reproduction.

Calcium is an essential nutrient for all ages, but many marketing campaigns for high-calcium foods focus on childhood. Do you think there’s merit to telling children to get their calcium because it builds strong bones? Explain your response.
Answer:
Yes
Explanation:
, there’s merit to targeting children in marketing campaigns for high-calcium food. People reach peak bone mass at about age 30. If children don’t consume enough calcium, they may not build up enough bone density, which could cause them to be at risk for osteoporosis when they’re older.
There is a lot of merit in telling children to get their calcium in building strong bones because the increase in bone density by calcium stops between 25-30 years.
It is therefore for the children to take enough of calcium to make their bones
very dense and strong as attaining the age of 30 years means there will be
no change in the bone density regardless of the amount of calcium taken.
Intake of calcium at an early age also helps us plan for old age . At the age of
50 years and above , individual experiences bone loss which leads to
osteoathritis and other bone related diseases.

How is a plateau different from a fault-block mountain?
Answer:
A plateau is defined as a highland area that has a flat top topography, which has steep sides. These are often formed when the intrusive magma crystallizes before it comes out to the surface. The flat top surface of the plateaus are formed due to the continuous erosion process that has taken place since the geological time.
On the other hand, a fault-block mountain is a type of mountain which are formed due to the reverse faulting. It results from the upward movement of the blocks. These are jagged mountains and are formed from the compressional stress.
Thus, the plateaus are formed from the erosion process, and fault-block mountains are formed due to the compressional stress.
