A. is incorrect because the cell displayed is an animal cell not a plant cell, so it cannot photosynthesize. The organelle shown is actually the ER.
B. is incorrect because the structure labelled is the nucleus, not a vacuole. Vacuoles store substances like waste, not DNA.
C. Is correct because the pickle-like organelle is the Mitochondria, also known as the powerhouse of the cell due to cellular respiration taking place there.
D. Is incorrect because the cellular membrane of the animal cell is not rigid like the cell wall of the plant cell, instead it is more semi-permeable.

Explanation:
Many rain forest plants are prone to developing fungal infections on their leaves. Fungi can grow rapidly in moist environments, and a serious infection can kill plants. One rain forest plant species has a genetic variation that affects its leaf structure. The traits and the descriptions of the plant’s leaves are listed in the chart.
Description
Trait A: medium-tip leaves Leaves are narrower toward the tips, but don't come to a full point. Most of the water drains from the leaves.
Trait B: drip-tip leaves Leaves come to a sharp point, leading to thorough water drainage from the leaves.
Trait C: wide-tip leaves Water runs onto the leaves and tends to pool in pockets at the tips.
During natural selection, organisms with harmful traits are less likely to successfully reproduce than organisms with beneficial traits. Neutral traits don’t improve or hurt an organism’s chances for survival. So, they tend to persist in populations when environmental conditions are stable. If the environment changes, neutral traits could become harmful or beneficial depending on the situation.
In year 1, a population of rain forest plants has the following distribution: 50% have medium-tip leaves, 25% have wide-tip leaves, and 25% have drip-tip leaves. You will simulate three years of this population: year 1, year 5, and year 10. How will the trait distribution most likely change over this time?
Answers
Year 1: 50% medium-tip leaves / 25% wide-tip leaves / 25% drip-tip leaves
Year 5: 40% medium-tip leaves /40% wide-tip leaves / 20% drip-tip leaves
Year 10: 30% medium-tip leaves /55% wide-tip leaves / 15% drip-tip leaves
I suppose medium-tip leaves become much less over the years is due to the fact withinside the description it says "Most of the water drains from the leaves." And as we recognize fungus likes cool and humid weather. Let us suppose that this plant is large and lives in a completely humid forest, and due to the fact the leaves can not keep water, a maximum of the water might pass at the floor subsequent to it. As we recognize vegetation that might be tall might have an extended shadow, and a fungus can develop below the plant due to the water maintains leaking thru the leaves, the humid temperature, and the shadow of the plant.
Next, I suppose that the wide-tip leaves will maximum probably be capable of living on higher is due to the fact whilst it rains maximum of the water will visit the middle or stem of the plant. (Like withinside the aloe vera plant there may be a bit socket withinside the center of the plant for water to move whilst it rains.) This approach that there might not be as lots water dripping out into the soil. Therefore this means that the soil won't be watery sufficient for a fungus to develop.
Finally, I suppose the drip-tip leaves might be 2nd for the maximum probable capability of life on is due to the fact despite the fact that the rain will usually pass into the soil, however, a few will nonetheless pass into the plant. I'm now no longer pronouncing that the medium-tip depart might not however I suppose that the drip-tip depart might capture extra rain than the medium-tip depart.
What are fungal infections of plants?
It generally causes stress. it is caused by soil, seed, weeds are spread by wind and water.
Hence it concludes that rainforest plants are prone to developing fungal infections on their leaves.

Answer:
Once released into the circulation, GH binds and activates the cell-surface GHR, as well as the related prolactin receptor in target tissues such as liver, muscle, bone, and adipose tissue

Direct effects are the result of growth hormone binding its receptor on target cells. Fat cells (adipocytes), for example, have growth hormone receptors, and growth hormone stimulates them to break down triglyceride and supresses their ability to take up and accumulate circulating lipids.

Which of the following is required for a trait to become more common
over time in a population? *
There must be many varieties of the trait in the population.
The trait must allow members of the population to eat only some kinds of foods.
The trait must be the result of an immediate change in the environment.
The trait must give individuals an advantage in producing offspring that survive.
Answers
Answer:Natural selection is a process that causes heritable traits that are helpful for survival and reproduction to become more common, and harmful traits to become more rare. This occurs because organisms with advantageous traits pass on more copies of these heritable traits to the next generation.

Why are nonrenewable resources used even when renewable resources might be available
Answers
Answer:
Why are nonrenewable resources used even when renewable resources might be available? At times, renewable resource use might be less efficient and more expensive than the use of nonrenewable resources.
Explanation:
Non-renewable resources are used very frequently in today's world. nonrenewable resources are used even when renewable resources might be available to cutoff the price and it is more effective.
What is the reason for using non-renewable resources?Nearly, 80 percent of the total amount of energy used each year is from fossil fuels.
Many of the works are dependent on fossil fuels due to they are energy-rich and relatively cheap to process.
Renewable resources can be sometimes less efficient and more expensive than the use of nonrenewable resources.
Thus, these factors can lead to the use of nonrenewable resources even when the option to use renewable resources is available.

Answer:
The correct answer is - 100 %
Explanation:
As we know DMD or Duchenne Muscular Dystrophy is a sex-linked recessive disorder and according to the given pedigree, it is clear that Individual I-1 is a normal male and 1-2 is a female who has two defective genes of the disorder as if she had only one defective gene she would have a carrier for the disorder.
All gametes produced by both male and female would be -
Male - X and Y
Female - Xd and Xd
Therefore all the male offsprings or son will get one defective gene Xh from the mother for sure and a Y chromosome from the father. All daughters will also carry one gene Xh that is defective from the mother and normal X from the father but would be carriers for the disorder.
Answer:
CORRECT (SELECTED)
100%.
Explanation:
Because individual I-2 is affected, she can only pass on a recessive DMD allele to her sons. This means that all of her sons will have DMD.

In genetics, a promoter is a protein-binding DNA sequence that initiates the transcription of a single RNA from the DNA downstream. This RNA can encode proteins, or it can have mobile functions, such as tRNA, mRNA, or rRNA. The promoter is near the starting site of gene transcription, upstream of the DNA (towards the 5 'region of the sense strands). The promoters can consist of about 100–1000 pairs

It is caused by an abnormal protein called a prion, which damages and ultimately destroys the brain and spinal cord tissue.
The disease is believed to have originated from the practice of feeding cattle with meat and bone meal derived from other animals, including sheep infected with a similar disease called scrapie.
BSE can also be transmitted from cow to cow through infected feed, or from a cow to a human who consumes contaminated meat. Therefore, the correct option is B.

Nitrate ions are needed by the gores plant for photosynthesis and for producing proteins
Explanation:
Nitrates ion are essential for producing amino acid which in turn is used for producing proteins. Nitrates is taken up by plants through the roots. Nitrates is vey essential for the photosynthesis of the plants. Without nitrate a plant cannot carry out photosynthesis and hence will not be able to produce food for itself and other living beings.
