Answer:
Set of crosses:
Wild-type male x light-green female
Light-green male x wild-type female
Explanation:
Chloroplast genes are inherited maternally and, therefore it would be expected to observe this mode of inheritance:
- Wild-type male x light-green female >> offspring 100% light green
- Light-green male x wild-type female >> offspring 100 % wild-type
Moreover, nuclear genes are inherited from both parents, and, therefore, in the case of complete dominance, it would be expected to observe the following results:
1- When wild type is dominant:
- Wild-type male x light-green female >> offspring 100% wild type
- Light-green male x wild-type female >> offspring 100% wild-type
2- When light-green is dominant:
- Wild-type male x light-green female >> offspring 100% light-green
- Light-green male x wild-type female >> offspring 100% light green

what is your role in maintaing the fertility status of our agriculture
Answer:
Soil fertility and nutrient management is one of the important factors that have a direct impact on crop yield and quality. Irrespective of the size of your field or plot, supplying plants with the right amount of nutrients at the right time is the key to a successful vegetable production enterprise.
Answer:
Microorganisms such as bacteria and fungi play an important role in maintaining the soil fertility. Microbial action on dead organic matter releases nutrients in the soil raising the fertility status of the soil.... raise the niteogen status of the soil by fixing atmospheric nitrogen

On a scratch sheet of paper, complete the Punnett square of the cross between two heterozygous red-eyed flies (Rr). What color eyes will the offspring have?
Answer:
75% red, 25% other color (brown?)
Explanation:
A cross between two heterozygous red eye flies (Rr x Rr)
R r
R RR Rr
r Rr rr
The possible genotypes are RR, Rr, and rr. There are two possibilities of Rr.
Since the heterozygotes have red eyes, the red eye allele must be dominant. Therefore, RR and Rr genotypes will all have red eyes. That means 3/4 (75%) of offspring will have red eyes. 1/4 25% are h0m0zygous recessive (rr), and will therefore have the other eye color (question doesn't mention which colour this is, it is likely brown)

If algae populations continue to decline, predict how this might impact the Great Barrier Reef food web.
Answer: the food web would crash.
Explanation: the great barrier reef's diversity would decline more and then the food web would crash since algae was the primary source, no ecosystem can live without a primary source to feed off of to gain energy and grow
Great barrier reef food web protects the coastline and is house to thousands of species. Algae is the primary producer on which the entire food web is based. If it continues to decline, ecosystem will crash.
The biggest coral reef in the world is the Great Barrier Reef. It is situated on Australia's northeastern coast. With a length of 1429 miles and more than 9,000 species, the Great Barrier Reef is enormous. One of the most biodiverse places on the globe, it. Over 3,000 different varieties of coral may be found on the Great Barrier Reef, yet despite supporting such a diverse range of life, the reef is threatened by climate change. Coral bleaching, which harms reefs and the creatures that dwell there, is being caused by changing temperatures and rising carbon dioxide levels.
A food web is a visual representation of how energy moves through an ecosystem. Food webs reveal which creatures in an environment devour one another. Trophic levels are divisions that can be made within food webs. Producers always come first in food webs.
Therefore, if algae (Primary producer) population continues to decline Great Barrier Reef food web will have a crash landing.

This picture shows the weather station model at a location.
Image shows a weather symbol with the following attributes: In the center is a circle that is entirely black. Surrounding this circle are several other symbols and numbers. To the left of the circle is a symbol that consists of three small black dots. In the upper-left corner of the model is the number 57; In the upper-right corner of the model is the number 107; In the lower-left corner of the model is the number 56; in the lower right corner of the model is the number -6. A line segment runs from the central circle through the upper left corner of the model; two smaller line segments - one larger than the other - connect to this line segment to form an 'F'.
What type of weather is expected at the location?

What is a thunderstorm?Some thunderstorms have a chance of producing hail and/or tornadoes. Localized heavy snow showers during the winter may also include thunder and lightning. Additionally, it frequently delivers heavy rain as well as violent gusts.
Thunderstorms are ferocious, brief meteorological disturbances that are nearly always accompanied by lightning, thunder, thick clouds, significant amounts of rain or hail, and strong gusts of wind.
Layers of warm, moist air rise in a strong updraft to cooler areas of the atmosphere, whereupon thunderstorms form.
Therefore, according to all directions shown in the image thunderstorm weather is expected at the location.

How many chromosomes will be found in
each of the two new cells formed as a result
of mitotic cell division?
23 pairs of chromosomes will be found in each of the two new cells formed as a result of mitotic cell division.
WHAT IS MITOSIS:
Mitosis is a kind of cell division that results in the formation of two daughter cells with the same number of chromosomes as the parent cell. Mitosis is used for growth and tissue repair in living organisms. In mitosis, a parent cell divides into two new daughter cells, however, each cell possess the same number of chromosomes as the parent. In a somatic human cell, there are 23 pairs of chromosomes (46 chromosomes). If this cell undergoes mitotic division, then, there will be 23 pairs of chromosomes in each cell formed.Learn more: https://brainly.com/question/3327479?referrer=searchResults

How did Claire's digestion reaction weights tell you that the problem was in her small intestine, and not in her stomach
Answer:
The reaction rate of the digestion helps in understanding which part of the digestive system having trouble in digestion especialy stomach and intenstine related.
It involves the fact that most of the enrgy or calories are get by the small intestine and also vitamins and minerals are absorbed by this part of the digestive system so if the small intestine is having problem the rate of digestion would be affected and and an individual could be malabosrbed.
If the problem lies in the stomach it might show some effects of a poor digestion, however the rate of digestion would be better than if the problem lies in the small intestine.

Explain how the structure of sperm cells is related to their function.
Please answer I will give brainliest to the first correct answer!
The structure of sperm cells as it relates to their function are:
The head: It helps carry the genetic information to the haploid nucleusThe acrosome: It helps the sperm enter the egg of the femaleThe middle piece: It is responsible for the release of energyThe tail: It helps the sperm to swimA sperm cell is the male sex cell which is responsible for reproduction as it fuses with the female gamete and forms a zygote through fertilization.
As a result of this, there are different processes which are required for fertilization to occur as the sperm cell has to move through the head and fertilize with the ovule to form a new cell, called zygote.
