Predict the results if promoters were not part of the transcription process. Please explain in detail!
Answer:
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

A. introducing a new species to an ecosystem
B. natural disasters
C. hibernation
D. migration
Answer:
hibernation
Explanation:
the rest definitely does
Answer:
C. hibernation
Explanation:
Exponential growth assumes that environmental factors like food, water supply, space, shelter, disease organisms, predators, weather conditions, and natural disasters do not affect the birth or death rate. As long as birth rate exceeds death rate (even slightly) population size will increase exponentially.

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.
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.

the roots of the gorse plant have bacteria that turn nitrogen gas into nitrate ions. Explain why nitrate ions are needed by the gores plant
Answer:
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.

Answer:
C
Explanation:
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.

With the help of labelled diagram explain the menstrual cycle in adolescent girls
Answer:
it is diagram okk
Explanation:
female reproductive system undergoes some changes and those changes repeat at interval of every 28-30 days. this repetative changes are called menstrual cycle. it is natural process, controlled by four hormones. those four hormones follicle stimulating hormone,luteinizing hormone, estrogen and progesterone. one of several follicle in ovary starts to develop along with oocyte present in it,under effect of follicle stimulating hormone. developing follicle secrets estrogen. endometrium of uterus starts to regenerate under effect of estrogen. it bursts under effect of luteinizing hormone and oocyte is released. this is ovulation. remaining tissues of burst follicle forms corpus luteum. corpus luteum starts to secrets progesterone. endometrial glands secrets their secretion under effect of progesterone. such endometrium is ready for implantation of embryo.
What are the target cells for the human Growth Hormone?
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
Explanation:
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.
Answer:liver, muscle, bone, and adipose tissue I think

In which era did human history begin?
A

Answer:
Prehistoric
Explanation:
The Prehistoric Period—or when there was human life before records documented human activity—roughly dates from 2.5 million years ago to 1,200 B.C. It is generally categorized in three archaeological periods: the Stone Age, Bronze Age and Iron Age.
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?
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.

Explain how the lungs are adapted for diffusion of gases
Answer:
well u know how we breath air in its the same as gas so your lungs are used to narcotics like smoking and vaping and stuff
Explanation:
Answer: Gas exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. As shown below, inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli.
Explanation: The alveoli are adapted to make gas exchange in lungs happen easily and efficiently. they give the lungs a really big surface area. they have moist, thin walls (just one cell thick) they have a lot of tiny blood vessels called capillaries.
