Answer:

Carrier proteins bound to the molecule, change shape, and transport the molecule through the cell membrane and onto the other side.

Given our understanding of neuroanatomy, we can confirm that the left cerebral hemisphere controls the muscles on the right side of the body and vice versa due to the motor decussate of the cortical spinal pathway.

A decussate in regards to the nervous system is described as when the nerve fibers cross from one side of the central nervous system to the other. The decussate in question corresponds to the cortical spinal motor decussate.

The cortical spinal pathway is the nerve pathway that is in charge of muscular control and therefore is the pathway that is responsible for the phenomenon described in the question.

There are no PHOTORECEPTORS in the OPTIC DISC located where the nerve fibers of the RETINA leave the eye and enter the OPTIC NERVE. This region is commonly called the BLIND SPOT.

The retina is an important layer of nervous tissue that covers the inside of the eye, in which the sensation of vision initiates.

Photoreceptors are specialized cells within the retina that respond to light stimuli. In the retina, there are two types of photoreceptor cells: cones and rods.

The blind spot is a small portion of the visual field of the eye that localizes in the optic disk within the retina.

There are no rods or cones (i.e. photoreceptor cells) within the optic disk.

Sickle cell anemia is persistent in the tropics because those with sickle cell anemia cant contract the malaria virus because of the shape of their blood cells, and this is advantageous in the tropics where there are more malaria cases. So those with sickle cell anemia live to pass on their genes.

Answer:

One drawback to using transgenic, knock-in, and knock-out mice to study human diseases is that many disorders occur late in life, and when genes are altered to model such diseases, the mutations can profoundly affect development and cause early death.

hope this helps

Explanation:

Genetically altered mice have served to recapitulate human diseases, including cancer, glaucoma, heart disease, and diabetes. However, despite their genetic similarity to humans, mouse models are criticized for their failure to accurately mimic human disease phenotypes.

Why it's bad to use mice as an experiment:

The use of mice as model organisms to study human biology is predicated on the genetic and physiological similarities between the species. Mice are less reliable as models of human disease, however, because the networks linking genes to disease are likely to differ between the two species.

Answer:

Gravity is associated with many erosional agents, because the force of gravity tends to pull all material down the slope. is when a rill channel evolves to become deep and wide. glaciers are dense so they can carry large rocks and debris for a long distance.

Role of gravity in erosion, because gravity tries to draw everything down the slope, gravity is linked to numerous erosional agents.

Glaciers and running water both erode due to gravity. This is a result of gravity pulling water and ice downward. These are examples of indirect effects of gravity on erosion.

Due to the force of gravity, mass movement is an erosional process that carries rocks and sediments down slope. The material is moved from higher heights to lower elevations, where it can be picked up and moved to even lower levels by other carrying mechanisms like streams or glaciers.

Therefore, glaciers and running water both erode due to gravity. This is a result of gravity pulling water and ice downward. These are examples of indirect effects of gravity on erosion.

Why was the theory of spontaneous generation a hindrance to the development of the field of micrbiology? Spontaneous generation, proposed by Aristotle, was believed for 2000 years. ... Although his experiment showed no spontaneous generation it was said that his sealed vials did not allow air for organisms to thrive.

Explanation:

Changes in an ecosystem may benefit one organism by removing predators while affecting the predator species negatively.

Changes that occur in an ecosystem may occur as a result of natural or man-made causes.

Changes in an ecosystem may have positive or negative effects on the interdependence of organisms in a specific habitat.

For example in an aquatic habitat where certain species of fishes like sharks depends on smaller fishes like salmon to survive, if humans were to reduce the salmon population by overfishing, the sharks will be negatively affected as they may have to migrate to new hunting grounds.

However, some other fishes that are prey to shark may be able to grow more with the reduction on shark population in that area.

Therefore, changes in an ecosystem may benefit one organism by removing predators while affecting the predator species negatively.

The relationship between population growth and technological change has been debated since the end of the eighteenth century a debate whose main configuration has proved remarkably persistent. During the ensuing 200 years, historically unprecedented rates of change have been observed in both variables: in industrial, commercial, and communications revolutions spreading out from Europe, North America, and Japan; in parallel (though spatially and temporally uneven) revolutions in the technological base of agricultural production; and in a demographic transition–in which mortality decreased and fertility first increased, then decreased that is still underway in many developing countries. Interconnections there must be, yet the attribution of primacy and direction of causation among these variables, not to mention the nature of the mechanisms involved and means of influencing outcomes in the interest of meeting social goals, remain controversial. Meanwhile, a new awareness of the emergence of complex social-environmental systems, whether at local or global levels, has extended the debate beyond the discipline of economics, and broadened its emphasis from the welfare of the human race to that of the planet.

Explanation: Transpiration is the loss of water from the plant through evaporation at the leaf surface. It is the main driver of water movement in the xylem. Transpiration is caused by the evaporation of water at the leaf–atmosphere interface. Up to 90 percent of the water taken up by roots may be lost through transpiration as only a small amount of that water is used for growth and metabolism.

Type of mutation reverses the direction of parts of a chromosome is inversion. The correct answer is option C.

The chromosomes are thread like structures present in the nucleus and the  these chromosomes carry the genetic information in them from one generation to another.

Inversion inverts the structure of chromsome and it basically turns the chromsomes inverted.

Inversion is the process where one arm of the chromosome gets detached from the basic structure and it gets attached in the inverted direction.

This  creates multiple copies of DNA turning it into genetic material and one of the X linked recessive disorders is haemophilia in which same type of mutation caused by the chromosome at the 8th position takes place.

Therefore, Mutation that reverses the directions of the part of the chromosome.

Answer:auditory tube

Explanation

The structure that regulates air pressure between the external atmosphere and the middle ear cavity is known as the Eustachian tube.

The ear is a type of organ of hearing and balance which consists of a cavity in the skull structure lined with soft tissue. It surrounds three distinct spaces filled with air or fluid i.e. the outer, middle, and inner ear. These specialized spaces host both the sound transmission apparatus and the sensory apparatus.

Types of bones present in the ear are

1. Hammer shaped bone known as malleus which is attached to the eardrum.

2. Anvil shaped bone known as incus present in the middle of the chain of bones.

3. Stirrup shaped bone known as stapes is attached to the membrane-covered opening which connects the middle ear with the inner ear (oval window).

The cavity of the middle ear is a narrow air-filled space which is a slight constriction divides it into an upper and a lower chamber known as tympanic cavity proper below and the epitympanum above. The main function of the Eustachian tube is to equalize the air pressure between the environment and the middle ear.

Thus, the structure that regulates air pressure between the external atmosphere and the middle ear cavity is known as the Eustachian tube.
