Answer:
Rotation is when an item or object (specifically the earth) rotates on it's axis.
Revolution is when an item (the earth) orbits or "revolves" around another one (the sun).
The rotation of the earth determines how long a day lasts while the revolution (or orbit) determines how long a year lasts (with all of the season).

Explain what is diffusion and osmosis? Why are they Important to the cell? Explain one example of active transport in the cell. Write a paragraph (5-7 sentences).
-if you help I really appreciate you!
Answer:
Diffusion and osmosis are both passive transport processes that act to equalize the concentration of a solution. In diffusion, particles move from an area of higher concentration to one of lower concentration until equilibrium is reached. Significance of Diffusion and Osmosis Both diffusion and osmosis are really important as these ensure the equalization of forces inside cells and also inside an organism as a whole by spreading all the necessary chemicals and nutrients from highly concentrated area to the low concentration area inside an organism. The intake of water in plants is an example of osmosis. Diffusion is observed when a drop of food coloring is added to a glass of water, where eventually, the entire water content becomes colored.

What influences other than humans affect genetic drift in populations?
Answer:
Every population experiences genetic drift, but small populations feel its effects more strongly. Genetic drift does not take into account an allele's adaptive value to a population, and it may result in loss of a beneficial allele or fixation (rise to 100% frequency) of a harmful allele in a population.

Briefly explain the neurophysiological basis (i.e. neuronal/axonal activity, synaptic behaviour) of how the monkey grip procedure
performed about the arms is able to cause a greater stretch reflex response in the leg for the same amount of sensory input when compare to a response without the monkey grip procedure.
The monkey grip procedure involves squeezing an object with one hand while the other arm is passively stretched that causes an increase in the stretch reflex response in the leg muscles of the same side that is being stretched.
What are the neurophysiological basis of the monkey grip procedure?The neurophysiological basis involves the activation of descending pathways from the brain modulating the stretch reflex response. When the grip is initiated, activation of motor areas in the brain increases that send signals down to the spinal cord.
These signals inhibit the interneurons activity that causes stretch reflex response causing a greater response in the leg muscles when they are stretched. The stretch reflex involves the activation of muscle spindles in the spinal chord that inhibit or excite the motor neurons that control the muscle.
The monkey grip procedure increases the excitability of the motor neurons controlling the stretched leg muscles that results in a greater stretch reflex response leading to a more forceful contraction of the leg muscles.
Therefore, the monkey grip procedure involves the complex interactions between descending motor pathways from the brain in the spinal cord that underlie the stretch reflex response.

Tortoises found on the Galapagos Islands can have varied phenotypes. One of the variations in the phenotypes is with regard to
their shells. They can have a domed shell with a hood above the head. The shells without domes lack the hood above the head,
such that the tortoise's neck is always pointing downward. A group of evolutionary biologists studied the tortoise population for
generations on these islands. The study coincided with a severe drought in the area that lasted many years. The data for the
changes in tortoise shell shape is shown here. Evaluate the data and select the statement that is best supported by this data.
Answer: B:The drought decreased the grass and vegetation on the ground, leaving only vegetation on shrubs and trees above the ground. Natural selection selected for the tortoises with the domed shells and hoods.

providing most of this oxygen?
fish and phytoplankton
plants and seaweed
seaweed and phytoplankton
coral and fish
Most living organisms need to take in oxygen to survive. It is responsible for plants and seaweed.
What are seaweeds?
Some seaweeds are microscopic, such as the phytoplankton that live suspended in the water column and provide the base for most marine food chains. Some are enormous, like the giant kelp that grow in abundant “forests” and tower like underwater redwoods from their roots at the bottom of the sea.
Most are medium-sized, come in colors of red, green, brown, and black, and randomly wash up on beaches and shorelines just about everywhere.
The vernacular “seaweed” is a bona-fide misnomer, because a weed is a plant that spreads so profusely it can harm the habitat where it takes hold.
Therefore, Most living organisms need to take in oxygen to survive. It is responsible for plants and seaweed.

Which situation is the best example of secondary succession?
A) An organism survives a difficult winter
B) The population in an area remains the same
C) One species replaces another species in an ecosystem after a forest fire
D) Each of several species uses the same amount of resources
Answer:
The answer is C
Explanation:
Secondary succession often occurs after a disaster, the ecosystem is not as primary as the primary succession, so it will take shorter time to recover. New species will occur in this place, and rebuild a constant environment. C is exactly the situation.
Hope this will help❤️
The best example of secondary succession is when one species replaces another species in an ecosystem after a forest fire. The correct option is C.
What is secondary succession?Secondary succession is a type of ecological succession that occurs on substrates that already have soil, and at least some organisms residing on it, like a forest or a community that has been disrupted by wildfire, tornadoes, or hurricanes.
The secondary succession in an ecosystem happens when a primary community is destroyed, for example, by wildfire. In secondary succession, the soil, seeds, and rhizomes survived in the soil and provides the foundation for the new community that is about to develop.
The rate of secondary succession varies according to the time taken for the primary community to regenerate, the level of disturbance of the habitat, the availability of propagules, and the dispersal capability of the species involved.
Therefore, the correct option is C.

4. A woman with defective tooth enamel (autosomal recessive) and normal color vision, (X-linked) who had a color blind father with normal tooth enamel and a mother with normal vision and defective tooth enamel, marries a color blind first cousin with normal tooth enamel who had a father with defective tooth enamel. What is the probability of their having a child with normal tooth enamel and color blindness
Answer:
The probability of their having a child with normal tooth enamel and color blindness is 3/8 or 0.375
Explanation:
Let the alleles for normal and defective tooth enamel be T and t respectively.
Color blindness is on the X-Chromosome. Let the allele normal vision and colour blindness be Xn and Xc respectively.
The woman had a colour blind father (XcY) and a normal vision mother, so her allelic pair for vision will be XnXc.
Her father had normal tooth enamel while her mother had a defective tooth enamel, therefore, she will have the allelic pair, Tt.
Her genotype for vision and tooth enamel will be XnXcTt.
Her husband who is color blind with normal tooth enamel had a father with defective tooth enamel, tt. Therefore, her husband's genotype for vision and tooth enamel will be XcYTt.
From the dihybrid cross of XnXcTt and XcYTt, the following offspring are obtained:
XnXcTT, XnXcTt, XnYTT, XnYTt
XnXcTt, XnXctt, XnYTt, XnYtt
XcXcTT, XcXcTt, XcYTT, XcYTt
XcXcTt, XcXctt, XcYTt, XcYtt
From the results of the cross, a child with normal tooth enamel and color blindness will have the following genotypes: XcXcTT, XcXcTt, XcYTT, XcYTt, XcXcTt, XcYTt.
Probability of their having a child with normal tooth enamel and color blindness = 6/16 = 3/8 or 0.375
