Answer:
B- The fused bones of the skull lessen the impact on the brain.
Explanation:
The brain is protected by the bones of the skull and by a covering of three thin membranes called meninges. The brain is also cushioned and protected by cerebrospinal fluid. This watery fluid is produced by special cells in the four hollow spaces in the brain, called ventricles.
Hope this helps!
The fused bones of the skull lessen the impact on the brain and help prevent injury to the brain.
What is the structure and function of the skull?
The skull consists of 22 bones in most adult specimens, and these bones come together via cranial sutures. The function of the skull is both structurally supportive and protective. The skull will harden and fuse through development to protect its inner contents: the cerebrum, cerebellum, brainstem, and orbits.
Does the cranium protect the brain?
Cranium. The eight bones that protect the brain are called the cranium. The front bone forms the forehead. Two parietal bones form the upper sides of the skull, while two temporal bones from the lower sides.

a. The applied force in the force of friction are balanced.
b. all four forces are the same size.
c. all four forces are acting in the same direction.
d. The applied force in the force of friction are unbalanced.
Answer: Its A.
Explanation:
None
The applied force and the force of friction are balanced in the picture because of which the person is standing still. Therefore option (A) is correct.
What is force?A change in the force that is applied to an item with mass will cause that thing to move at a different speed. A body's state of rest or motion can be altered by the application of an external agent known as force. It is significant in both magnitude and direction.
The term "frictional force" refers to the force that is produced when two surfaces come into contact with one another and then slide against one another. A few factors that affect the force of friction are as follows: These forces are primarily influenced by the surface texture as well as the amount of force that is drawing them closer together.

Search the NIH gene database for the term colorblindness. Use the results of the database search to explain how a father and mother who are not colorblind could have a son who is colorblind. Your model can be a pedigree chart, a Punnett square, or a diagram of chromosomes.
Answer/Explanation:
Red/green colorblindness is a recessive, X-linked condition. That means that the affected gene is on the X chromosome, and that the phenotype will only be present if there is no "healthy" gene, which is dominant to the mutated gene.
For two unaffected people to have an affected son, the mother must be a carrier. Remember, females have two X chromosomes and males have one. So if a female is a carrier of the colorblindness mutation, she will have one copy of the mutation and one normal copy of the gene, and will therefore be unaffected.
The punnet square (attached) shows that all their female children would be unaffected (have the B gene), but 1:2 male children would be colorblind, as their only copy of the gene is mutated (b).

Which statements could be categorized in the "Asexual" section of the Venn diagram? Check all that apply
Answer:
The right answer are : mitosis, diploid cells, and identical DNA.
Explanation:
The answers "two cell divisions" and "gametes" refers to a division by meiosis which is a sexual reproduction.
Asexual reproduction or asexual reproduction is a mode of reproduction, which - as opposed to sexual reproduction - corresponds to the capacity of living organisms to multiply alone, without a partner, without involving the fusion of two gametes of opposite sexes. Asexual reproduction is observed in multicellular (animal and plant) and unicellular organisms. In botany, the term often used for the asexual multiplication of plants is vegetative multiplication. In all cases of asexual reproduction, the result is identical to the mother.

What statement is correct about the polarity of a water molecule?
summarize how small, nonpolar molecules enter and leave the cell (and why).
Answer:
Small, nonpolar molecules (ex: oxygen and carbon dioxide) can pass through the lipid bilayer and do so by squeezing through the phospholipid bilayers. They don't need proteins for transport and can diffuse across quickly.
Explanation:
The channel proteins act like doors through the cell membrane.
They allow large polar molecules to move in and out of the cell.
The process is called passive diffusion or passive transport, because it does not need energy.
Sometimes the protein changes shape to help the polar molecules move through the channel.
It often uses a gated pore mechanism, in which the channel is never completely open.

Stomata are pores in the leaves of plants that allow gases to enter and exit the cells.
During the sunniest part of the day, the leaves are most actively performing photosynthesis.
During this time, which gas do the stomata allow into the leaf cells?
Answer:
carbon dioxide
Explanation:
In most plants, the roots absorb water from the soil. The water travels up through the xylem, a specialized layer of cells. In some plants, the water is absorbed through the leaves, directly from the air. Carbon dioxide, an atmospheric gas, enters the leaf through the stomata, the tiny pores in the leaves (a stoma is a single pore).

what natural causes destroy ponds
Answer:
invasive species
Answer:
In the explanation. :)
Explanation:
The water in a pond must remain clean if it is to provide a healthy environment for the organisms (animals and plants) living in it. The natural waste from the living and dead organisms is ‘recycled’ by special tiny organisms called bacteria. Plenty of oxygen is needed for the bacteria to ‘break down’ the waste. The pond can take care of its own waste – it’s people who cause pollution!
The most noticeable kind of pollution is the dumping of rubbish – anything from old cars and drinks cans to bikes and bottles have been found cluttering up ponds. This not only makes the environment look so unsightly but it may also destroy pond-life.
Perhaps the most serious threat to ponds is chemical pollution as a result of modern farming methods. Over the years fields have been sprayed with pesticides to rid the crops of pests. However, rain often washes the excess chemicals off the crops into nearby ponds, streams or rivers, poisoning some of the animals living there. Fortunately, these poisonous chemicals are not used so freely now and, hopefully, this problem will gradually be reduced.
Another, equally serious, problem connected with agriculture is the use of artificial fertilizers. Powdery chemical fertilizers, containing nitrates, are put on the crops to help their growth but they can also be washed off by rain into nearby ponds. They do not poison the wildlife but the rich supply of nitrogen causes the water plants, especially algae, to grow very quickly. The plants use up so much oxygen during the night and during decaying processes that there is none left for the other pond-life. The growth also prevents sunlight reaching the organisms below. Eventually, all the algae die leaving a smelly, decaying mass. The case of excess nitrates in water is called eutrophication.

Explain the law's of segregation and independent assortment.
Answer:
The law of segregation states that the two alleles of a single trait will separate randomly, meaning that there is a 50% either allele will end up in either gamete. This has to do with 1 gene. The law of independent assortment states that the allele of one gene separates independently of an allele of another gene.

a. arid desert
b. coastal desert
C. cold desert
d. none of the above
Please select the best answer from the choices provided
B
ОООО
С
D
Answer:
A
Explanation:
Among the options given, the arid desert represents an example of the classic hot and dry desert. Thus, the correct option for this question is A.
What are the characteristics of the hot and dry deserts?Hot and dry deserts have extremely hot climates and challenging environments. There is very little biodiversity in hot deserts because of the harsh climate. Few species are specialized enough to survive there. Apart from this, the climate is very dry with less than 250 mm of rainfall a year.
According to the context of this question, cold deserts have extremely low temperatures and snowfall. While coastal deserts occur in cool to warm areas along the coast. They have cool winters and long, warm summers. Coastal deserts are located on the west coasts of continents between 20° to 30° latitude.
Therefore, the arid desert represents an example of the classic hot and dry desert. Thus, the correct option for this question is A.
