Explanation:
Its when several proteins work together and fold and concentrate prokaryotic DNA. Folded DNA is then organized into a variety of conformations that are supercoiled and wound around tetramers (a molecule with four structurale subunits) of the HU protein.
Usually unicellular (some cyanobacteria may be multicellular)
---> The process of selecting a few organisms with desired traits to serve as parents of the next generation. Selective breeding of plants and animals to promote the occurrence of desirable traits in offpsring.?
The process of determining a few creatures possessing desirable characteristics to participate as the founders of the coming generation is Artificial selection.
Artificial selection
The discovery of advantageous characteristics among living things by humankind, as well as the efforts performed to improve and maintain such traits throughout upcoming populations or years.
It follows the same procedure as evolutionary processes, with the exception that with biological evolution, nature determines the decisions rather than humans.
Thus the above response is correct.

When Mendel crossed hybrid pea plants, he observed that certain traits would appear in the next generation more often than others. He also observed that traits did not show up in offspring in predictable combinations. For example, not all tall plants had green peas, while not all short plants had yellow peas. Which term describes this observation?
A. Dominance
B. Sex Linkage
C. Segregation
D. Independent Assortment
The law of independent assortment describes that it is not necessary for the plant to have only the predictable observations. New combinations of characters can also develop in plants. Thus, the correct option is D.
What is Independent Assortment?Mendel in his laws of genetics described that there are two different alleles present for all the characters in an organism where, one allele is dominant and the other is recessive.
The principle of Mendel's law of independent assortment describes how the different genes separate from each other independently when the reproductive cells develop in an organism. Independent assortment of genes and their corresponding traits were observed for the first time by Gregor Mendel in 1865 during his studies of genetics in the garden pea plants (pisum sativum).
Therefore, the correct option is D.

One result of climate change is that ocean temperatures are increasing. If the temperatures continue to rise, what effect will that have on the oceans’ ability to retain CO2? How might this change affect the atmosphere? THIS IS SCIENCE WOULDNT LET ME SELECT IT
Answer:
See explanation
Explanation:
There is an equilibrium that exists between the carbon dioxide in the air and the carbon dioxide in the oceans. The temperature of the water affects its ability to hold carbon dioxide.
Hence, as the global temperature continues to rise and the water becomes warmer, its ability to hold carbon dioxide decreases. When this happens, the gas exchange across the air-ocean boundary is affected. There is now too much CO2 in the atmosphere owing to the disturbance of its air- ocean exchange equilibrium leading to more rise in temperature due to global warming.
List two types of chemical erosion
Answer:Oxidation and Hydrolysis
Answer:
The most vivid examples of chemical erosion are caves and sinkholes created in areas with a lot of underground limestone that ends up dissolving from acidic groundwater.
Explanation:
Hydrolysis - the breakdown of rock by acidic water to produce clay and soluble salts. Oxidation - the breakdown of rock by oxygen and water, often giving iron-rich rocks a rusty-coloured weathered surface.

differentiate between the structure and function of the following plant cell organelles cell membrane, cell wall, nucleus, cytoplasm, mitochondria, chloroplasts, and vacuole
Answer:can you break it down for me
Explanation:it needs to be explained to me first for me to understand
The cell wall is only found in plants, whereas the cell membrane is found in all living organisms, including plants. Only found in plants and a few fungi, bacteria, and algae. Introduce in all types of cells, including humans, animals, plants, and bacteria.
What is a cell?In biology, the base unit that can live by itself and is made up of all living organisms and body tissues.
Photosynthesis occurs in chloroplasts; cell walls allow plants to be strong and upright; and vacuoles help regulate how cells handle water and other molecules.
Mitochondria provide metabolites for epigenetic modifications and other nuclear-associated activities, and mitochondrial proteins have been discovered in the nucleus.
The material or protoplasm within a living cell, excluding the nucleus, is referred to as cytoplasm.
Whereas the nucleus is a dense organelle present in most eukaryotic cells, typically a single rounded structure bounded by a double membrane, containing the genetic material.
Thus, these are the basic differences between plant cell organelles cell membrane, cell wall, nucleus, cytoplasm, mitochondria, chloroplasts, and vacuole.

How is a renewable resource different from a nonrenewable one?
A. A renewable resource is more likely to run out.
B. A renewable resource can never be replenished.
C. A renewable resource has a higher demand
D. A renewable re purse is replenished faster than it is used
Answer:
Explanation:
d
A renewable resource is different from a nonrenewable one by the fact that a renewable resource is replenished faster than it is used. Thus, the correct option for this question is D.
What is a Renewable resource?A renewable resource may be defined as a type of resource that significantly continues to exist in nature despite being consumed or can replenish itself over a period of time even as they are utilized by the organisms.
Examples of renewable resources may include wind power, solar energy, geothermal energy, biomass, etc. These resources are available in nature in unlimited amounts as compared to non-renewable resources.
Therefore, a renewable resource is different from a nonrenewable one by the fact that a renewable resource is replenished faster than it is used. Thus, the correct option for this question is D.

Calculate the number of liters of liquid that are in Lake Erie, which has a volume of 484 cubic km (km3). Express your answer in scientific notation.
Answer: The answer in scientific notation is [tex]4.84\times 10^{14}[/tex]
Explanation:
The conversion factor is : [tex]1km^3=10^{12}L[/tex]
Given : Volume of liquid in Lake Erie = [tex]484km^3[/tex]
To find : Volume of liquid in Lake Erie in units of liters
As [tex]1km^3=10^{12}L[/tex]
Thus [tex]484km^3=\frac{10^{12}}{1}\times 484=484\times 10^{12}L[/tex]
The answer in scientific notation is [tex]4.84\times 10^{14}[/tex]

Altos niveles de ATP en la célula son necesarios para realizar ciertas funciones vitales tales como reproducirse.A qué piensas que se deba esto
Answer:
el ATP es la moneda energética que la célula utiliza para llevar a cabo diversas funciones metabólicas (incluida la reproducción)
Explanation:
La adenosín trifosfato (ATP) es la principal fuente de energía para la mayor parte de los procesos celulares. La hidrólisis del ATP libera energía química almacenada en los enlaces de fosfato de la molécula, la cual es utilizada por la célula para llevar a cabo diversas funciones, incluida la reproducción. La hidrólisis de ATP genera en primera instancia adenosín difosfato (ADP) y un grupo fosfato libre (ortofosfato), esta es una reacción exergónica que libera una enorme cantidad de energía la cual es utilizada por la célula para llevar a cabo diversas funciones metabólicas incluyendo la síntesis de macromoléculas tales como, por ejemplo, proteínas del huso mitótico requeridas durante el proceso de división celular. El ADP también puede hidrolizarse para liberar energía, con la consecuente producción de adenosín monofosfato (AMP) y un segundo fosfato libre.
