Answer:
Jennifer observes a weather map showing tomorrow's weather. She predicts that air will travel from the high pressure system to the low pressure system, causing wind. The wind will carry moisture since it is coming from the ocean.
Explanation:
Winds refers to the movement of air which are produced due to differences in air pressure.
These pressure differences are to uneven heating of the earth by the sun. Due to the uneven shape of the earth, regions around the equator receive a fairly consistent heating from the Sun. However, with increase in latitude north and south, there is more uneven heating of the earth's surface by the Sun. When air is heated, warm air rises up to the atmosphere. This produces a pressure difference and subsequently cold air sinks downward to replace it. This constant air movement results in winds. The winds generated moves from a high pressure system to a low pressure system. The greater the pressure difference, the greater the wind force.
When warm air from land rises, air from the ocean in to replace it. The wind coming from the ocean is moisture-laden, and results in precipation on land.

How can humans use mutations to produce traits we want?
Answer:
mutations can affect an organism by changing its physical characteristics (or phenotype) or it can impact the way dna codes the genetic information (genotype). when mutations occur they can cause termination (death) of an organism or they can be partially lethal.
good luck :)

Within a population of rabbits, black fur (B) is dominant over white fur (b). A scientist observes 16% white rabbits on an island. The dominant allele frequency of this population is
Answer:
Explanation:
According to hardyweinberg principle
p+q= 1
P2+2pq+q2=1
given that
Black fur =B =p(dominant allele)
White fur =b =q (recessive allele)
q2=16%
16/100=0.16
q=√0.16
q=0.4
Since p+q=1
P=1-q
P=1-0.4
P=0.6
Therefore the allele frequency for dominant organism Black fur is 0.6

Cells typically respond to DNA damage in three ways: by ceasing to grow and divide until the damage is repaired, by permanently ceasing to grow and divide, or by dying. In 2010 a group of scientists reported that a certain kind of immune reaction can cause DNA damage that leads to a fourth response. DNA damage can turn off genes involved in cell-signaling pathways. Turning off these genes can cause less-mature cells to divide too rapidly, often leading to the development of- a. tumors c. hemophilia b. allergies d. cardiovascular disease
It can lead to the development of A. Tumors
Turning off these genes can cause less-mature cells to divide too rapidly, often leading to the development of (A) tumors.
What is the most common cause of tumor?
When cells reach their end of life cycle or get damaged, they pass away and are replaced by new ones. This normally well-regulated process can, on occasion, become disorganized, allowing aberrant or damaged cells to proliferate and reproduce when they should not. These cells have the potential to develop tumors, which are mass accumulations of tissue.
There are primarily three different kinds of tumors:
Benign: These tumors do not have any cancer-causing properties. They do not penetrate the tissue that is close by and they do not spread to other areas of the body.Tumors that are premalignant have cells that are not currently cancerous but have the capability of developing into cancerous cells in the future.Malignant: Malignant tumors are malignant.Learn more about tumors, here:

Stem tuber ---- Potato
Conditioned reflex ---- Pavlov's experiment
Blood circulation ---- William harvey
Pancreas ---- Insulin
Autotrophs ------ Blue green algae
Active transport ---- Minerals
Note: Chlorosis has no matching item in the list. Explanation is given below.
Explanation:
Stem tubers are plants which store their food in their stems. Potatoes are stem tubers.
Conditioned reflex is a reflex is acquired gradually by training in association with specific repeated external stimuli. For example, the Russian psychologist Ivan Pavlov's performed experiments on conditioned reflex using a dog. He demonstrated that a dog will salivate on the sound of a bell even if there is no food given to it if the ringing of the bell preceded every feeding session of the dog.
William Harvey discovered the circulation of blood and the function of the heart .
The islets of Langerhans found in the Pancreas secretes the hormone, insulin.
Autotrophs are organisms which are able to manufacture their own food, Blue green algae are examples of autotrophs.
Active transport is transport which requires expenditure of energy and occurs against the concentration gradient of the substance being transported. Because the concentration of minerals in the soil are in very low concentration, active transport is used by the root hair cells carrier proteins to move mineral ions across the membrane into the cell against the concentration gradient. ATP hydrolysis provides the energy for this process.
Chlorosis is a disease which appears as the yellowing of leaves in plants and in human a green tinging of the skin which is caused by the deficiency of minerals especially iron and manganese.

archaea are more or less similar to eukaryotes than bacteria
Answer:
Although archaea superficially resemble bacteria in terms of size and cellular organization (members of both groups lack nuclei), they are surprisingly similar to eukaryotes at the molecular level. For instance, all archaea replicate their DNA and synthesize proteins using molecular machines like those of eukaryotes.
A population of lizards carry a gene for scale color in which the dominant allele produces green scales while the recessive allele codes for brown scales. In the first generation, you determine that 75% of the population is green and 25% of the population is brown. In the second generation, you determine that 50% of the population is green and 50% of the population is brown. Finally, in the third generation, you determine that 25% of the population is green and 75% of the population is brown. Which of the following correctly explains this change in the genotype frequencies?(1 point)

What is photosynthesis, and what is it's main goal?
Answer: Photosynthesis is the process of when a plant makes it's own food, and the main goal is to convert solar energy to chemical energy.
Explanation: Plants use photosynthesis by taking the sunlight, to synthesize foods from carbon dioxide and water. Since plants can't move and consume other organisms, they use photosynthesis. The formula is: [tex]6CO_2+6H_2O=C_6H_1_2O_6+6O_2[/tex].
Like I said, the main goal is converting solar energy to chemical energy then store the chemical energy for future use, for example it can be used for Chemical batteries, Natural gas, Heat, Food, etc.

B. Lots of small plants, because the big trees provide more oxygen.
C. Very few small plants. because the trees use up all the oxygen.
D. Lots of small plants, because the trees provide enough water.
(I'm in 5th grade btw, and I have a big test coming up so this could really help)
Answer:
A.....
Explanation:
,.............
If a forest has many large trees with lots of leaves, the likely thing that could be found on the ground is very few small plants, because the trees block all the sunlight. Thus, the correct option for this question is A.
Why do plants that live on the forest floor have big leaves?The forest floor gets almost no light at all. Leaves in these environments have adapted to low light and lots of water. Large leaves are arranged horizontally to absorb the most light possible. This is because these plants have plenty of access to water, and they can keep large leaves alive.
The plants that live on the floor of the forest have bigger leaves so that they can absorb the little light that comes through rather the plants that live in hot sunny conditions don't need to store as much sunlight. Cacti are plants that live in extremely dry environments.
Therefore, if a forest has many large trees with lots of leaves, very few small plants would be found on the ground because all the trees block the sunlight. Thus, the correct option for this question is A.
