The capacity of the backbone is to secure the spinal line, yet it additionally needs to take into consideration developments, for example, twisting around or turning from side to side. The a wide range of fragments of bone consider this bowing or bending significantly more than a solitary bone stretching out from the neck to the coccyx could. The circles of ligament serve two or three capacities. One, they help to interface each of the individual vertebral bones and avoid separation. Two, they keep the crushing of bone on bone that would happen if the vertebral bones were in coordinate contact.

What is the role of mRNA in expressing specialized structures
Citrus2011 [14]

The messenger RNA is a single-stranded intermediate molecule that transfers the genetic information from DNA to the cytoplasm, which is used as a template to assemble the chain of amino acids that form a variety of polypeptides. Therefore, mRNA is the blueprint for protein synthesis, which is read according to the genetic code during gene expression.

Match each scenario to its related biomolecules. Jack is eating a diet that will help him build muscle, so he eats a diet high i
Stells [14]

The options for this question are as follows:

A. Nucleic acids

B. Carbohydrates

C. Fats

D. Proteins

Now the correct answers of the match are as follows:

Jack is eating a diet that will help him build muscle, so he eats a diet high in this. <u>D. Proteins</u>

Explanation: Proteins help to build up the muscles. That's why people who want to do body-building, eat protein rich foods, like chicken, eggs, soy, etc.

Before a race, Ruth drinks a beverage full of this biomolecule to get energy. <u>B. Carbohydrate </u>

Explanation: This biomolecule provides instant energy to our body. For example, glucose is consumed before race, as dissolves quickly in our blood and provides instant energy. Glucose is an example of simplest carbohydrate.

These molecules in olive oil will help Ruth’s body store long-term energy. <u>C. Fats </u>

Explanation: Fats are the kind of biomolecule which is stored in our body in the adipose tissues. Also, when glucose is all used up by our body cells, the body starts to get energy from this stored fat.

Elizabeth has been advised to go for genetic screening to detect any abnormalities in her unborn child. <u>A. Nucleic acids </u>

Explanation: Every cell of our body has DNA, and it contains all the genetic information about the whole body. DNA is a kind of nucleic acid. If Elizabeth is going for test of the abnormality, it means she is going to test for the DNA of her child.

Which of the diagrams shows red blood cells in 0.0 M Solution​
Julli [10]

The rigth answer is the picture 4.

In the case of a hypotonic extracellular medium, there will be a large inflow of water to dilute the Na, thereby increasing the cell volume and there will be an explosion of the membrane in places so hemolysis, the contents of the red cell ( Hemoglobin) is released into the blood plasma.

On the other hand, in the case where the extracellular medium is hypertonic, therefore archi concentrated, well it will be the water of the red cell that will come out without damaging the membrane, we will rather have a red cell that is completely flat and non-functional without release. erythrocyte (Hb) content.

Describe how human activities cause desertification including desertification’s impacts on soil and the role of modern agricultu
Ghella [55]

Answer:

Desertification is the destruction of the biological potential of the land and it is generally viewed as an advanced stage of land degradation. human activities also cause the process such as poor irrigation practices, deforestation, the expansion and intensive use of agricultural lands, and overgrazing.

Such human activities put enormous pressure on the land by altering its soil chemistry and hydrology. Modern agriculture causing a negative impact on the soil and land by overexploiting the biological and chemical potential of the land.

In the polymerization in vitro of actin filaments and microtubules from their subunits, what does the "lag phase" correspond to?
nalin [4]

Answer:

Nucleation

Explanation:

The first step of formation of new phase, structure or self-assembly is called as Nucleation.

It is mentioned in the book of Molecular Biology of the Cell that whenever, In-vitro polymerization of micro-tubules and actin filament occur the first step is called nucleation. In other words Lag Phase.
