Explanation:
Cell specialization is the differentiation of cells to perform very specific function. At the stage of cellular differentiation, the generic cells are transformed into very specialized cells.
Multicellular organisms have very complex body systems. They carry many different tasks. They have to move, find food, excrete, maintain balance within their body system and the environment etc.
To perform these tasks, cells must have specific functions because they would be in need of different materials to carryout the functions.A unicellular organism performs very simple functions of life. They do not require complex biological processes to manufacture their food and carry out life activities.
Cell specialization occurs in large multicellular organisms but not in small unicellular organisms because multicellular organisms have numerous cells but unicellular cells have only one cell.
CELL SPECIALIZATION:
Cell specialization is a phenomenon in living organisms in which different cells perform different and specific functions for the organism that contains them. Cell specialization strictly occurs in multicellular organisms i.e. organisms that possess more than one cell. This is because there are numerous cells to carry out specific tasks.On the other hand, in a unicellular organism i.e. organism that contain only one cell, cell specialization cannot occur. Therefore, cell specialization occurs in large multicellular organisms but not in small unicellular organisms because multicellular organisms have numerous cells but unicellular cells have only one cell.Learn more about cell specialization at: https://brainly.com/question/12683466?referrer=searchResults

Name 2 body systems that interact to maintain
homeostasis in the human body and explain how they do
Answer:
Internal Temperatures
Similarly, the cardiovascular, integumentary (skin and associated structures), respiratory, and muscular systems work together to help the body maintain a stable internal temperature. If body temperature rises, blood vessels in the skin dilate, allowing more blood to flow near the skin's surface.
OR,
The nervous and endocrine systems exert the ultimate control over homeostasis because they coordinate the functions of the body's systems. Regulation of body temperature, blood pressure, pH, and glucose concentration are four examples of how the body maintains homeostasis.

From which hot spot would you view Polaris at an altitude of 45 degrees?
Answer:
Massena, New York
Explanation:
Polaris is most popularly known as the North star. It is also famous by the name of "Pole Star". It is the closet to the north celestial pole. At present it is the northern pole star currently.
It is found in the constellation of Ursa Minor. It is the one of the brightest star seen in the night sky. It is considered the star of the second magnitude which is situated close to the heaven's north pole.
The altitude of the Pole star or the Polaris when an observer is at the Tropic of Cancer is measured at 23.5 degree. While if the observer sees the Pole star at its zenith, the observer is located at the North Pole. i.e. 90 degree.
And the spot from where the observer views the Polaris at 45 degree altitude is Massena, New York.

Which of the following describes how both of these cellular division processes maintain genetic continuity?
А.Both processes involve the replication and division of identical genetic material.
B. Both processes creates cells with half the genetic material of the parent cells.
C. Both process involve the recombination and division of new genetic material.
D. Both processes create cells with twice the genetic material of the parent cells.
Answer: Both processes involve the replication and division of identical genetic material
Explanation:
During S phase interphase DNA is replicated and it is replicated as an exact copy
When a single cell divides into two cells through mitosis, genetic continuity occurs. One cell divides into two during the process of mitosis, and each of the two progeny cells has the same amount of DNA as the parent cell.
What is genetic continuity?The fact that when a cell divides, the resulting two daughter cells have the same number and type of genes as the original cell is referred to as genetic continuity. It also describes how when two sexually reproducing organisms mate, their offspring have the same number of genes as the parents. Nuclear division results in daughter cells with identical sets of chromosomes. Mitosis ensures the genetic continuity of the ancestral cells in the body's daughter cells. It consists of one fully equational division followed by a DNA synthetic phase. Because it creates a perfect copy of DNA for new cells, DNA replication helps to maintain species genetic continuity.To learn more about Genetic continuity refer to:

Organize the parts of this body system in the CORRECT order (starting with is organism level) according to levels of organization in a multicellular organism
Answer:
neurons - nerve tissue - brain - central nervous system - human being.
Explanation:
Reason: The Levels of Organization is organizing how everything in a human body is put together. Example: Neuron (or cell), tissues (that are made from cells that come together), heart (is created when groups of tissues come together), circulatory system (is made when other groups of organs come together to form a system that work with each other to maintain life), and then the is carries on with other systems that together form the human body
The major levels of organization in the body, from the simplest to the most complex are: atoms, molecules, organelles, cells, tissues, organs, organ systems, and the human organism.
What do you mean by levels of organization?Biological organization is the hierarchy of complex biological structures and systems that define life using a reductionistic approach. The traditional hierarchy, as detailed below, extends from atoms to biospheres.
The scientific study of the different levels of organization of living beings, helps us gain an insight into the complexities of their structure and functioning. Every organism on Earth, from the smallest to the largest one, follows this establishment.
Using the circulatory system as an example, a cell in this system is a red blood cell, the heart's cardiac muscle is a tissue, an organ is the heart itself, and the organ system is the circulatory system. An organism is made up of four levels of organization: cells, tissues, organs, and organ systems.

In your opinion, what are the three most important molecules needed for the production of ATP? Explain your reasoning.
To produce the energy required to drive ATP synthesis, the human body requires three different types of molecules: lipids, proteins, and carbohydrate.
What molecules are required for the production of ATP?
In the mitochondria of a cell, the process of cellular respiration also results in the formation of ATP.
This can be done through either anaerobic or aerobic respiration, depending on whether oxygen is present.
ATP is produced during aerobic respiration from glucose and oxygen, along with carbon dioxide and water.
ATP hydrolysis provides the energy needed for many essential processes in organisms and cells.
These include intracellular signaling, DNA and RNA synthesis, Adrenergic signaling, synaptic signaling, active transport, and muscle contraction.
Therefore, lipids, proteins, and carbohydrate are important molecules in production of ATP.

Fair weather can usually be expected with the approach of _____.
a cyclone
an anticyclone
a low-pressure system
Answer:
Anticyclone
Explanation:
Fair weather can usually be expected with the approach of a high pressure system or an anticyclone.
Fair weather can usually be expected with the approach of an anticyclone that is present in the second option, as the anticyclone is a high-pressure system that is characterized by descending air.
What is an anticyclone?An anticyclone is a high-pressure system that is characterized by descending air, the descending air in an anticyclone is warmed by compression as because it prevents cloud formation and precipitation as it moves closer to the surface, an anticyclone typically brings clear skies, calm winds, and generally pleasant weather. A low-pressure system or cyclone is characterized by rising air, which creates an unstable and potentially stormy atmosphere, as the air rises, it cools and forms clouds, which can lead to precipitation and thunderstorms.
Hence, fair weather can usually be expected with the approach of an anticyclone, which is present in the second option.
