Mitosis is the correct answer. Mitosis is when a cell splits in two identical cells.
Why is burning fossil fuels not considered carbon neutral
Answer:
Maybe this will help
Explanation:
Burning either fossil fuels or biomass releases carbon dioxide (CO2), a greenhouse gas. However, the plants that are the source of biomass for energy capture almost the same amount of CO2 through photosynthesis while growing as is released when biomass is burned, which can make biomass a carbon-neutral energy source.

Explain the difference between a pseudocoelom and a true coelom
Answer:
A pseudocoelom is a body cavity that lies between mesodermal and endodermal tissue and is, therefore, not completely surrounded by mesodermal tissue. A “true” coelom is completely surrounded by mesodermal tissue, and can thus be subdivided into compartments.
Explanation:
What are the events unique to Mitosis?
This cell is in which stage of mitosis?
Choose 1 answer:
A) Early prophase
B) Late prophase (prometaphase)
C) Metaphase
D) Anaphase
E) Telophase
Answer:
B) Late prophase (prometaphase)
Explanation:
In this stage the centrioles duplicate and move towards the cell's opposite poles.The nucleolus and nuclear membrane gradually disappear.The movement of centrioles occurs because of the spindle fibres which are growing between them.So, this cell is in the stage of prometaphase.Hope you could understand.

Which best defines color?
a physical property of matter related to a material’s ability to reflect light
a physical property of matter related to how a material interacts with different wavelengths of light
a chemical property of matter related to a material’s ability to reflect light
a chemical property of matter related to how a material interacts with different wavelengths of light
Answer: It's A.
Explanation: The definition of color is a component of light which is separated when it is reflected off of an object. The appearance of objects or light sources described in terms of the individual's perception of them, involving hue, lightness, and saturation for objects, and hue, brightness, and saturation for light sources.
A color can be best defined as the physical property of matter which is related to a material's ability to reflect light. Thus, the correct option is A.
What is a Color?
Color is the physical property of an object or substance with respect to the amount of light reflected by the object. It is determined visually by the measurement of hue, saturation, and brightness of the reflected light by an object.
Physical properties of the matter may be subdivided into intensive and extensive properties. An intensive property of matter include color, density, temperature, and melting point. It is a bulk property that does not depend on the sample size but the quality of the sample. Reflectivity is a physical property of matter which is related to the amount of light that a material reflects on absorption of light.
Therefore, the correct option is A.

Tissue engineering combines living cells with synthetic materials to create functional substitutes for human tissues. What components would you use to engineer replacement for (a) skin, (b) bone, (c) muscle, and (d) blood?
Answer:
I believe the answer would be skin. Have a Blessed evening :)
Explanation:
Tissue engineering is a process in the dead, damaged or functionally dead tissues are removed and can be placed with a new functional tissue. Skin is the most common example of this. Thus, option a is correct.
What is tissue engineering?Tissue engineering is an emerging branch in medical biosciences that involves grafting of new cells or tissues in place of non-functional and damaged tissues.
Skin tissue grafting is commonly done in case of superficial burns. A part of the skin cells for example from the thigh region is taken and can be grafted to some other region such as face or neck.
Tissue engineering is also commonly performed in dental science for gum and palate grafting. It can also be applied to some organs in the body for restoring their damaged or altered function by using the stem cells.
Thus, tissue engineering can be considered as boon in regenerative medicine science.

Suppose you are studying epigenetic modifications in the Genetics lab. You isolated the chromatin of Symbiodiniaceae from an anemone and used electron microscopy to examine the chromatin structure. You observed he chromatin structure is similar to ours, like beads on a string. After several tries of different techniques, you are able to analyze the core histones of the Symbiodiniaceae obtaining the following results:
Histone Percentage
H1 25%
H2A 12.5%
H2B 25%
H3 12.5%
H4 0%
H8
(new histone) 25%

In what latitudes are equatorial biomes often found?answers-
-Between 0° and 23.5° south
-Between 23.5° south and 23.5° north
-Between 23.5° north and 60° north
-Below 60° south and above 60° north
Answer:
Between 23.5° south and 23.5° north
Explanation:
The Tropical Forest biome has equatorial latitude therefore 23.5°N (the Tropic of Cancer) and 23.5°S (the Tropic of Capricorn) would be the answer because those are the mainly ranged locations of latitude.
Equatorial biomes are often found between 23.5° north and 23.5° south latitudes. Hence the correct option is B.
Equatorial biomes are characterized by their proximity to the equator, the imaginary line that divides the Earth into the Northern Hemisphere and the Southern Hemisphere. These biomes typically occur between 23.5° north and 23.5° south latitudes. It receives a high amount of direct sunlight and experiences little temperature fluctuation due to the Earth's axial tilt.
Within this range, we find diverse and lush equatorial biomes, such as tropical rainforests and tropical savannas. Tropical rainforests are known for their high biodiversity, with an abundance of plant and animal species, while tropical savannas are characterized by a mix of grassland and scattered trees and support a variety of wildlife.
Hence the correct option is B.
