Answer:
3 Neurons are the specialized cells responsible for allowing all the basic body functions to take place correctly as all the necessary communication happens through them. Muscle cells or myocyte cells are specialized in making all movement possible. These cells have a cylindrical shape that allows them to contract.
Explanation:
4 Each cell must be able to perform as a part of a living organism. Cell specialization is required for cells to perform as a part of a whole living thing. Different cells do different jobs.
Why is grafting considered asexual reproduction and not sexual

The period of revolution of the earth is called a ?
Orbit
Day
Year
Month
Answer:
Explanation:
A year is defined as the time it takes a planet to complete one revolution of the Sun, for Earth this is just over 365 days. This is also known as the orbital period. Unsurprisingly the the length of each planet’s year correlates with its distance from the Sun as seen in the graph above.
Answer:
a year
Explanation:
The amount of time it takes for a single trip around the sun is called a period of revolution. The period for the Earth to revolve around the sun is 365.24 days or one year.

why cellular respiration and photosynthesis are a
cycle.
Cellular respiration and photosynthesis are referred to as a cycle because the end product of one process serves as the starting material for the next reaction. During cellular respiration, sugar and water are the starting materials, and carbon dioxide and water are the byproducts. Water and carbon dioxide are the starting material for photosynthesis.

True or False: Because the microbiome is important for fitness, many organisms have developed specific strategies for passing the microbiome on to progeny.
The statement 'because the microbiome is important for fitness, many organisms have developed specific strategies for passing the microbiome on to progeny' is TRUE. It is natural selection in action.
According to the evolutionary theory proposed by Darwin, natural selection is the mechanism by which species change (evolve) to adapt to particular environmental conditions.
In this case, the microbiome represents an evolutionary adaptive mechanism, thereby natural selection will tend to favor individuals that have a beneficial microbiome.
In consequence, individuals having a beneficial microbiome will have more chances to reproduce and survive (i.e., they have higher adaptive fitness), thereby they also have more chances to pass this adaptive trait to the next generation.

Say that you look at the nuclei of 100 skin cells taken from the same person. About how many of these skin cells would you expect to be in interphase
Answer:
45 cells would be in the interphase
In the nuclei of 100 skin cells. The number of skin cells would be in interphase is 45.
What are cells?Cells are the key unit of living organisms. The cell divides into many cells through the process of cell division.
Prokaryotic cells are the primitive type of cells that are present only in unicellular organisms, and they do not undergo cell division. These cells do not have true cell organelles and a nucleus, in that DNA is present in coil form in the cytoplasm. They contain ribosomes the organisms are bacteria that contain prokaryotic cells.
Eukaryotic cells are higher cells that contain cell organelles they have to perform various complex functions of large organisms. They have a nucleus which contains DNA or genetic material, it does not have flagella.
Therefore, the number of skin cells in the interphase is 45 cells.

How do the baby’s respiration and circulation change when the baby is born?
Answer:
Oxygen and carbon dioxide flow through the blood in the placenta. Most of it goes to the heart and flows through the baby's body. At birth, the baby's lungs are filled with fluid. ... Increased oxygen in the lungs causes a decrease in blood flow resistance to the lungs.

Generalized global air circulation and precipitation patterns are caused by ________.
A. solar radiation that warms moist air masses near the equator, which then cool and release precipitation as they rise, and then, at high altitude, move north or south of the tropics and sink back to the surface as dry air masses
B. air masses that are dried and heated over continental areas, which then rise, cool aloft, and descend over oceanic areas, followed by a return flow of moist air from ocean to land, delivering high amounts of precipitation to coastal areas
C. polar, cool, moist, high-pressure air masses from the poles that move along the surface, releasing precipitation along the way to the equator, where they are heated and dried
D. solar radiation that warms dry air masses at the poles, causing them to sink toward the tropics, gain moisture, and then release it as precipitation.
Answer:
option B is the right answer
Generalized global air circulation and precipitation patterns are caused by air masses that are dried and heated over continental areas, which then rise, cool aloft, and descend over oceanic areas, followed by a return flow of moist air from ocean to land, delivering high amounts of precipitation to coastal areas. The correct option is B.
What is differential heating?The reason we have different weather patterns, jet streams, deserts, and prevailing winds is due to global atmospheric circulation caused by the rotation of the Earth and the amount of heat received by different parts of the globe.
The earth's polar regions are both cold, owing to the fact that they receive far less solar radiation than the tropics and mid-latitudes.
Air masses that are dried and heated over continental areas cause generalized global air circulation and precipitation patterns.
This is then rise, cool aloft, as well as descend over oceanic areas, accompanied by a return flow of humid air from ocean to land, achieving higher amounts of precipitation to coastal areas.
Thus, the correct option is B.

The left cerebral hemisphere controls the muscles on the right side of the body and vice versa. Which pathway generalization best explains this phenomenon
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.

Which statement contains inaccurate information about stem cells?
Stem cells are undifferentiated.
Stem cells are specialized.
Stem cells can make more cells of the same type through cell division (potentially indefinitely).

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.

As wind passes over a mountain, the side over which the wind rises tends to be ____________________ and the side that experiences the downward movement of air tends to be ____________________.
drier; moist and rainy
moist and rainy; drier
rainforest; desert
desert; rainforest
Given what we know about the effects of air currents on mountain ranges we can confirm that the correct option is option B, moist and rainy on one side while being dier on the other.
Mountains are described as having two sides in regards to their relationship with the air currents. The side of the mountain on which the wind rises is known as the windward side, whilst the side on which air descends is known as the leeward side. The windward side is typically in contact with warmer, moist air from the ocean and other bodies of water.
When coming in contact with the mountain, the air is forced to rise and begins to cool, which often leads to rain or snow. The leeward side of the mountain receives the air that has now already lost the majority of its moisture with its pass through the windward side of the mountain. This air also tends to become warmer as it descends, which explains the dry nature of the leeward side of mountains.
