2. How do cells produce new cells for growth and repair?
Answer:
The process of mitosis generates new cells that are genetically identical to each other. Mitosis helps organisms grow in size and repair damaged tissue.
Explanation:
Answer:
The process of mitosis generates new cells that are genetically identical to each other. Mitosis helps organisms grow in size and repair damaged tissue. ... Some organisms can use mitosis to reproduce asexually. The offspring of asexual reproduction are genetically identical to each other and to their parent.
Cells make copies by dividing into two cells in a process called mitosis. As the parent cell divides, it passes on its genetic instructions to both copies. The new cells look and function just like the parent. Eventually, each of the new cells will divide, too.
Dead cells can make new cells in order to grow and also to replace old dead cells. The process by which new cells are made is called cell division.

Answer: Taxonomy
Explanation:
The relationship between the amount of energy available for use and the amount of entropy in a food chain differs between trophic levels. why would the amount of entropy increase from one trophic level to another in a food chain or energy pyramid? a. the available energy from one trophic level to another increases b. energy is lost at each level as heat, which increases randomization c. the amount of biomass decreases from one trophic level to another d. the available energy at each level may either increase or decrease, creating randomization please select the best answer from the choices provided a b c d
The energy in the pyramid is entropy as it helps in the energy transfer energy from the trophic level the correct option is energy is misplaced at every tropic stage as warmness and serves to growth entropy.
The strength glide via meals chain and meals webs comply with the second regulation of thermodynamics. At every tropic stage, the handiest 10% strength is surpassed in the following stage and relaxation 90% is misplaced as warmness. Therefore, strength switch via meals chains continually finally ends up with lesser usable strength. The strength misplaced in the surroundings in the shape of warmth has a tendency to grow the entropy of the system. The better the tropic stage, the greater the warmth to be had to growth entropy.What is an energy pyramid?
A strength pyramid additionally called atrophic or ecological pyramid is a graphical illustration of the strength located in the trophic degrees of an ecosystem. The backside and biggest stage of the pyramid is the manufacturers and includes the biggest quantity of strength.
Thus it is clear that energy is lost at each level as heat, which increases randomization.

As you move from right to left on the periodic table, what happens to the number of protons and neutrons in atoms?
As you move across a period, the atomic mass increases because the atomic number also increases. When the atomic number increases, this means that there are more protons and neutrons that add to the atomic mass of an atom. The atomic mass for any given atom mainly comes from the mass of the protons and neutrons
it might be late but honestly my fault for not checking any earlyer
Usually, the three ecological pyramids look similar in shape. Sometimes, a pyramid of numbers does not have the usual pyramid shape, even though the other two pyramids for the same ecosystem do. We reviewed this twice in class. Explain the reason that sometimes a “pyramid” of numbers does not have a pyramid shape, and be able to draw the shape of this “pyramid”.

Mr. Bailey decides to do an experiment to see if different types of popcorn pop faster in the
microwave. The TV commercials say that Popalicious is the fastest popping popcorn in the
world. Mr. Bailey's hypothesis was, "If I pop Jiffy Pop, Popalicious, and Pop-Tastic popcorn in a
microwave, then the Popalicious will pop faster because the commercial says so." He takes
Jiffy Pop, Popalicious, and Pop-Tastic and places them each in the microwave for 2 minutes.
After two minutes is up, he counts the number of POPPED kernels in the bag. After three trials,

The statements that describe the functions of the circulatory system are as follows:
Oxygen is delivered to cells throughout the body by this system.Nutrients are delivered to organs through this system.This system removes carbon dioxide from organs and delivers it to the lungs.This system plays a major role in fighting infections.What is the Circulatory system?The Circulatory system may be defined as a type of organ system that significantly involves the sequence of organs that togetherly work in order to circulate blood throughout the body. Examples of this organ system may include the heart, blood vessels, lymphatic vessels, and some glands.
According to the function of the circulatory system, it usually helps the body to fight against infections due to the role of white blood cells. The respiratory system significantly works along with the circulatory system in order to inhale atmospheric oxygen and exhale carbon dioxide through the lungs. But they are not the function of the circulatory system.
Therefore, the statements that describe the functions of the circulatory system are well described above.
