Imagine that you discover three different bacterial species on a meteorite. Each species contains genetic material that is not D
jeka94

Answer:

Species A: 2

Species B: 56

Species C: 162

Explanation:

Codons are sequence of 3 purine or pyrimidine bases that codes for amino acids. Each codon in mRNA eventually binds with anticodon in tRNA during protein synthesis and gets translated into their respective amino acids. Hence, the number of amino acids in each of the species represents the minimum number of codons in each species.

<em>Therefore, species A with 2 amino acids will have a minimum codon length of 2, species B with 56 amino acids will have minimum of 56 codons while species C with 162 amino acids will have minimum codon length of 162.</em>

Which of these is not a property of lymphatic capillaries?
Inessa05 [86]

Answer:

They are smaller than blood capillaries.

Explanation:

Lymphatic capillaries drains the extracellular fluid present between the cell spaces. The fluid is known as lymph as it enters the lymph capillaries. These capillaires drains into lymph vessels that drains to lymph nodes and lymph ultimately enters the venous circulation.

Lymphatic capillaries are slightly larger than blood vessels and these capillaries have close ends. The walls of lymph capillaries are made up  of endothelial cells. The endothelial cells overlap in lymph vessels and when the pressure in ECF is greater these cells move and create a sort of gap for the movement of ECF inside the lymph capillary but when the pressure inside the capillary is greater these cells again overlap and does not allow the lymph to move outside of capillary. Thus lymph capillaries only allow the ECF to enter the capillary but does not allow the lymph to go out from capillary. Lymph capillaries have greater internal pressure than blood vessels.

How does the environment affect the organism, and vice versa? What effects, good as well as bad, have humans had on the environm
Rudik [331]

1. The environment is detrimental for the survival of the organisms. It is what provides the organisms with all of the living conditions, thus we can say that it is the ''stage'' to which the organisms have to adapt in order to survive in it. The organisms though also have effect on the environment. The organisms are able to contribute to numerous natural cycles, they give the material for the formation of soil, affect the composition of the atmosphere, and all of that has huge impact on how the environment looks and what it can provide.

2. The humans have had huge impact on the environment, both bad and positive. Unfortunately, the bad effects are the dominant ones, and they include pollution of all spheres, destroying the environment in order to free space for their own needs, changing the environment in accordance to their interest without taking in consideration the long term done. From the positive side, the humans have managed to transform multiple arid and semi-arid regions and make them green, bring water in places where it has been lacking, stop the major wildfires.
