earth can support the survival of organisms.what is/are the factory/s that make/s earth habitable?
Answer:
The factors that make Earth support the survival of organisms are it's correct distance from the sun, the Earth is protected by solar radiation by it's magnetic field, stability of it's warm atmosphere, availability of some chemical composition that support life like oxygen, water, nitrogen e.t.c., proximity of the sun in allowing the passage and flow of water, the shape and size of the Earth as Rocky planet e.t.c.
Explanation:
Earth is the planets that support the survival of living organisms and this is because of the following factors that support the existence of life and these factors includeit's correct distance from the sun, the Earth is protected by solar radiation by it's magnetic field, stability of it's warm atmosphere, availability of some chemical composition that support life like oxygen, water, nitrogen e.t.c., proximity of the sun in allowing the passage and flow of water, the shape and size of the Earth as Rocky planet e.t.c.
It's correct distance from the sun makes it's to have stable temperature i.e not to hot and not too cold. With the temperature, living organisms can survive and live.
Earth is protected from solar radiation by ozone layer and it's magnetic field. This layer hinders the penetrations of some harmful Ray's it radiations that can damage it destroy living organisms.
It's allow water flow and water is essential for life . It is useful for plants for growth , photosynthesis and germination. Water is essential for animals because, it's aids digestion and metabolic processes.
Earth's atmosphere have right composition of chemicals that support life and these chemicals include oxygen, nitrogen, carbon, water e.t.c.
For example oxygen is important for respiration which releases energy to perform cellular activities.

Explanation:
hope this helps
Answer:
The cell structures that are common to all cells include the DNA or the genetic material; the cytoplasm, which is the fluid where the organelles are suspended in it; plasma membrane, also referred to as the cell membrane that serves as the cell's barrier to the external environment; and the ribosomes, which are the organelles in charge of producing proteins

Erwin Chargaff is considered one of the pioneering scientists in the field of molecular biology. In one of his studies, Chargaff observed that a sample of human DNA contained approximately 30% adenine (A). Based on DNA structure, what are the expected percentages of the other nitrogenous bases in the sample?
A.
10% thymine, 40% cytosine
B.
20% thymine, 30% cytosine
C.
30% thymine, 20% cytosine
D.
40% thymine, 10% cytosine#
Answer:
30% thymine, 20% cytosine
Explanation:
In a typical DNA double helix pyrimidine; Cytosine and thymine always pair with Purine ;Adenine and Guanine. This pairing ensure that the double helix of DNA is maintained by the presence of Hydrogen between these organic bases.
For correct pairing all adenine must pair with thymine,and all Cytosine with guanine.Therefore for this to occur if 30 % of adenine is present,the composition and number of thymine(30%) must be available.If this percentage is not available the pairing will not occur.
Like wise 20% Cytosine must be present because ,then same amount of Guanine molecule 20% in the DNA molecule. must be present Thus Guanine percentage is 20%.
This give a total of 100(60+40)
This based on the Erwin Chargaff stoichiometric ratio of 1:1 .This states that the percentage of adenine =thymine,and that of Guanine=Cytosine,in the DNA of living cells should be equal. Thus; [A]+[G]=[C]+[T]=1:1

How do the molecular formulas for all the amino acids differ?
The molecular formulas for all the amino acids differ - the R group or side chain.
Each amino acid has the same molecular structure with a central carbon atom, the alpha (α) carbon, bonded to an amino group (NH2), a carboxyl group (COOH), and to a hydrogen atom.
Each amino acid is exactly the same except for the R group. little side chain represented by the will be different depending on the kind of amino acid.For example, glycine has a hydrogen atom as its R group, whereas alanine has a methyl group (CH3).Thus, the molecular formulas for all the amino acids differ - the R group or side chain.

Explanation:
An engineer made a model of a ship to help him think about how it works ha made sure that some characteristics of the ship were accurately represented but he did not include all of the ships characteristics in his model is it okay that he ignored some of the ships characteristics
Answer:
Yes it is ok
Explanation:
This usually depends on what the engineer is trying to accomplish or learn. For example, if the engineer is simply trying to understand how the architecture floats or cuts through the water then he does not need to model the engines or other unnecessary characteristics. On the other hand, if the engineer wants to understand how the engine provides power to the entire ship then he would need to model the engine and all the connected parts but not the outer exterior of the ship. Therefore, it is ok that he did not model the ship completely as long as it provides the information needed.

Water makes up a large percentage of the body’s cells. For a cell to remain in homeostasis, there must be a mechanism to control water changes in the cells. The movement of water from an area of high water concentration to an area of low water concentration is
A.Diffsion
B.stable transport
C.Active transport
D.Osmosis
Answer:
osmosis
Explanation:
on edge2020
The movement of water from an area of high water concentration to an area of low water concentration is called as Osmosis. Thus option D is correct.
What is osmosis ?The process in which solvent molecules pass from a lower concentration based solution to a higher concentration solution through a semipermeable membrane called as osmosis.
It is a passive process as no external energy is needed.
When a living plant cell kept in a sugar or salt solution, water diffuses from the cell sap out through the cell membrane called as ex-osmosis.
The cell causes shrinkage of the protoplasm due to water loss, where the cell undergo a condition called as plasmolysis or necrosis.
When the plasmolysed cell is placed in distilled water, the cell regains it’s turgidity and also the original shape and size by a process called endosmosis.
This condition is called deplasmolysis or cytolysis. Thus option D is correct.
