In a process called ____________ , genetic material is exchanged between homologous chromosomes. This occurs during this stage of cell division: ____________ .
In a process called crossing over, genetic material is exchanged between homologous chromosomes. This occurs during the prophase stage of cell division.
What is crossing over?Crossing over is the unique process by which genetic material is exchanged between the non-sister chromatids of homologous chromosomes.
Crossing over occurs in the prophase stage of meiosis and ultimately results in the formation of genetic combinations in offspring that are not present in the parents.
Therefore, the process called crossing over, genetic material is exchanged between homologous chromosomes and it occurs during the prophase stage of cell division.

23. An unknown solution is colorless when tested with phenolphthalein but causes the indicator phenol red to turn red. Use this information to find the approximate pH of this solution.
Phenolphthalein is a weak acid and is colorless in solution. It is generally used to find out the endpoint of titration. As the An unknown solution is colorless when tested with phenolphthalein but causes the indicator phenol red to turn red it indicates the pH of the solution is 8.0 or above.
What is phenol red?Phenol red is an indicator whose color can exhibit a gradual transition from color yellow to red.
Phenol red is actually a water-soluble dye as is used as a pH indicator, changing from yellow to red over pH 6.6 to 8.0.
Thus, it can be concluded that the pH of the given unknown solution is in range 8.0 or above.

Answer:
B.
These resources are nonrenewable and will eventually disappear.
Explanation:
Answer:
B. These resources are nonrenewable and will eventually disappear.
Explanation:
Fossil fuels take millions of years to form, but we mine and use them at a rate that is much faster than their replenishment time. That means that, at some point, we will use up all of the available fossil fuels before new ones can be formed.

why might stem cells from human embryos be more useful than stem cells
from adults?
Answer:
Embryonic stem cells are more useful than the adults stem cells because;
* Embryonic stem cells have the ability to create any cell type in the human body while, the adults stem cells are more specialized( they generally make cells only from their tissue of origin).
They have the capacity to divide into additional stem cells or any kind of body cell.
What is the importance of stem cells of embryo?Embryonic stem cells can develop into any type of human cell, whereas adult stem cells are more specialized and typically can only produce cells from the tissue from which they originated.
Additionally, it is simple to produce embryonic stem cells in a lab setting. There is always the option to manufacture more cells as needed because the cells can be developed through cultures.
Since embryonic stem cells are pluripotent, they are more adaptable in scientific experiments than adult stem cells. Finding novel treatments for ailments, wounds, and organ failure is one of the possible advantages of studying embryos.
Therefore, Embryonic stem cells are more useful than the adults stem cells.

6. Photosynthesis can combat global warming. Explain with reasons.
Plants take carbon dioxide (CO2) out of the atmosphere to do photosynthesis, and thus help reduce the greenhouse gases warming the planet.
Explanation:
Plants, through photosynthesis, and soils sequester roughly a third of carbon dioxide emissions released into the atmosphere each decade from the burning of fossil fuels. During photosynthesis, plants open tiny pores on their leaf surfaces to suck carbon dioxide from the air and produce their own food.

2. What are three characteristics of carbon that contribute to the diversity of organic compounds?
Catenation:
The property of self linkage among identical atoms to form long chain compounds is known as catenation. Carbon exhibits maximum catenation, when compared to elements like sulphur and silicon, due to strong carbon-carbon bonds and tetra valency. Due to this catenation, carbon atoms can form various types of straight chains, branched chains and ring structures.
Formation of multiple bonds:
Carbon atoms are capable of forming multiple bonds with other carbon atoms.
Hydrocarbons:
All the carbon compounds which contain just carbon and hydrogen are called hydrocarbons.
isomerism arises from the difference in the structure of carbon chain which forms the nucleus of the molecule. It is, therefore, named as chain, nuclear isomerism or Skeletal isomerism. For example, there are known three pentanes which have the same molecular formula.

What is a zygote and how is it formed
Answer:
A zygote is a fertilized ovum. The germ cells undergo meiosis to reach a haploid state (n) as part of spermatogenesis and oogenesis. The sperm and the unfertilized ovum reinstates a chromosome set in zygote in a diploid state (2n).
After fusing with the sperm, the second stage of meiosis takes place for separation of chromatids. Post-fertilization, mitosis of the zygote is initiated which develops into a mature offspring exhibiting characteristics of its parent.
Explanation:
The zygote stage development occurs in the first week of fertilization. The genome of the zygote is the combination of DNA in each gamete and contains all the genetic information required to form an individual.
Answer:
Zygote is a diploid cell resulting from the fusion of two haploid gametes
it forms when a sperm penetrates the outer surface of an egg.
