21.As mentioned in the video, the environment can also affect an organism's traits. The example of nourishment was used in the case for Spike, as this could affect his growth and size. This can also occur in humans. UV light was not mentioned in the video. How could UV light potentially affect an organism's trait? Provide one example.
Answer:
UV light can modify the DNA of a human being, provoking mutations that affect the traits. For example, exposure to the sun's UV rays affects the DNA of the skin cells, causing mutations that can lead to cancer.
Explanation:
An environmental factor that can affect humans traits is the exposure to UV light that the sun radiates. The DNA in our skin cells absorbs the UV rays. As a result, the DNA can suffer modifications that result in skin cancer. Also, the absorption of UV rays causes wrinkles since cell components are affected due to the accumulation of UV light.

how does nonradom matting affect the gene pool
Answer:
I think it's, the nonrandom mating is defined solely in terms of departures from HW proportions for neutral alleles, without reference to phenotypes. The impact is measured in terms of genetic parameters, such as genetic variance, expected gene flow, and Δ F, assuming the infinitesimal model and mass selection.

How does the process of DNA replication impact mutations in an individual?
a All DNA replication stops when there is a mutation so the mutation wont hurt the individual
b Replication only produces new DNA strands so the old stand with the mutation is destroyed
c Since replication keeps the old strands as templates mutations maybe earned into future stands
d Mutations are often lost since the cell will die doring the replication process if the DNA is mutatie.
Answer: A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke. Mutations can occur during DNA replication if errors are made and not corrected in time.

Francis grew some plants for a science experiment. The sketch of his experiment after several days is shown. Which tropism is Francis most likely investigating?
The correct answer to this open question is the following.
Unfortunately, you did not provide the sketch or the photo that shows what Francis is doing. So we do not know what you are talking about.
However, trying to help you, we did some deep research and can comment on the following.
If the photo shows a plan under the light of a lamp, moving towards the lamp direction, then tropism is Francis most likely investigating is phototropism.
To better understand the concept, Tropism is the movement of a plant towards the direction of an influence exerted on it. This means that an external factor is introduced in order to make the plant grow through an external influence.
So when we use the term phototropism, this means that the plant responds to the direction of the source of light and grows in that direction. That is what Francis is using in his science experiment.
Answer:
phototropism

2. How do gene splicing and gene therapy differ? How are they alike?
Gene therapy and gene splicing are separate but linked processes. A new organism can be created by cutting and recombining genetic material from two separate sources, a process known as gene splicing.
What is gene splicing ?It is a technique that scientists utilise in the lab to develop new organisms with desired features. On the other side, a healthy gene is introduced into the patient's cells during a medical process called gene therapy to treat diseases and disorders.
Gene splicing and gene therapy share certain similarities despite their distinctions. Both procedures entail the modification of genetic material, frequently derived from several sources, in order to produce the desired outcome.
The goal of gene splicing is the development of a new creature or its modification.that of an active organism. Treatment of a disease or disorder is the intended outcome of gene therapy. Both procedures also entail the manipulation of genetic material using specialised methods, such as recombinant DNA technology. Finally, for both methods to be effective, a good understanding of genetics is necessary.

Is the ocean a carbon sink or a carbon source
Answer:
Explanation:
The Carbon CycleChanges to The Carbon CycleThe Ocean and CarbonBiological Pump
The ocean plays an important part in the carbon cycle. Overall, the ocean is called a carbon ‘sink’ because it takes up more carbon from the atmosphere than it gives up.Carbon dioxide from the atmosphere dissolves in the surface waters of the ocean. Some of the carbon dioxide stays as dissolved gas, but much of it gets turned into other things. Photosynthesis by tiny marine plants (phytoplankton) in the sunlit surface waters turns the carbon into organic matter
the ocean is a carbon sink
Forms across a plant cell during cytokinesis.
A. cleavage furrow
B. pinching in
C. cell plate
Answer: A. a ring of actin filaments forms at the metaphase plate. The ring contracts, forming a cleavage furrow, which divides the cell in two. In plant cells, Golgi vesicles coalesce at the former metaphase plate, forming a phragmoplast.
Explanation:
hope this helps have a great day❤️❤️❤️
Answer:
ty for helping me now ill help you
a
Explanation:
cytokensis is the physical process of cell division. It divides the cytoplasm of a parental cell into two different daughter cells.
In plants, a cell wall forms. Cytokensis occurs in mitosis and meiosis. The objective for cytokensis is to divide the parent cell into two daughter cells. So cytokensis in plants is when a cell wall forms in between the daughter cells. Plant cells have walls, so they CANNOT divide using a cleavage furrow. A cell plate forms across the cell during telophase.
In animal cells, cleavage furrow forms. This pinches the cell in half and forms two different cells.

Include the mean
Summarize the data
Tell you whether to call your mother about your results
Give a measure of statistical significance
Answer:
A, D, and E is correct
Explanation: I took the test and got this one correct.
The items that are inferential statistics among the options would be:
Give the likelihood of data occurring by chanceTell you whether to call your mother about your resultsGive a measure of statistical significanceThis is largely due to the fact that inferential statistics refer to the branch of statistics that draws conclusions from a set of data. It is as opposed to descriptive statistics which focus on summarizing, describing, arranging, and or categorizing data in such a way that trends are shown at a glance.
Statistical parameters such as mean, mode, and median only measures attributes of data relating to the measure of central tendencies. Data summary is purely descriptiveHence, the items selected are those that are conclusive and not descriptive.

natural selection is an example of a mechanism of evolution. does this mechanism produce a change in individuals or populations? explain
Natural selection refers to the procedure where the species better amended to their surrounding appear to survive and generate more offspring. Natural selection refers to one of the mechanisms that make modifications in the frequencies of genes in populations and thus, it is the mechanism of evolutionary change.
However, the phenomenon of genetic drift and natural selection cannot take place unless and until there is a genetic variation, that is unless some individuals are genetically distinct from others.
Jill uses a magnet to pick up a nail. Then, she touches the nail to a paper clip and picks up the paper clip. What will most likely happen when she pulls the magnet away from the nail?
The paper clip will stay attached to the nail because the nail is now a permanent magnet.
The paper clip will stay attached to the nail because the paper clip is now a permanent magnet.
The paper clip will fall off of the nail because the nail was only a temporary magnet.
The paper clip will fall off of the nail because the nail is now magnetized in the opposite direction.
Answer:
C but see below.
Explanation:
e. The paper clip will likely fall off because it wasn't attached to the nail long enough to be magnetized.
The same answer would apply to the nail. It likely was not held onto the magnet long enough to pick up a magnetic force that would be strong enough to overcome the gravitational force pulling on the clip.
Of the four answers you have given us, I would agree with C. But as I've argued above, the real reason is likely there.
