When does a cell grow in size

Chemistry
2 answers:
NNADVOKAT [17]3 years ago
7 0

Answer:

For a typical dividing mammalian cell, growth occurs in the G1 phase of the cell cycle and is tightly coordinated with S phase (DNA synthesis) and M phase (mitosis). The combined influence of growth factors, hormones, and nutrient availability provides the external cues for cells to grow.and if u want to know does it grow in size Body tissues grow by increasing the number of cells that make them up. ... When cells become damaged or die the body makes new cells to replace them. This process is called cell division. One cell doubles by dividing into two.

Explanation:

hope it help and if it doesnt sorry ;)

The increase in size and changes in shape of a developing organism depend on the increase in the number and size of cells that make up the individual. Increase in cell number occurs by a precise cellular reproductive mechanism called mitosis.

artcher [175]

Answer:

The <u>equilibrium constant</u> is:

              k_c=0.0030M^{-2}

Explanation:

The correct equation is:

  •   N₂(g)    +    3H₂(g)    ⇄    2NH₃(g)

Thus, with the equilibrium concentrations you can calculate the equilibrium constant, Kc.

The equation for the equilibrium constant is:

         k_c=\dfrac{[NH_3]^2}{[N_2]\cdot [H_2]^3}

Substituting:

        k_c=\dfrac{(0.105M)^2}{(1.1M)\cdot (1.50M)^3}

         k_c=0.0030M^{-2}

A piece of glass is immersed in a liquid. It proceeds to float on the liquid's surface. This shows that the density of the glass
tamaranim1 [39]

Answer: b) Less dense

Explanation:

Differences in density is one reason objects float or sink.

An object more dense than the fluid in which it is immersed will sink, while objects less dense than the fluid in which it is immersed will float to the surface.

But objects floats at constant level if the density is equal to the density of the fluid in which it is immersed; it neither rises nor sinks in the fluid in this case.

In an experiment, 4.14 g of phosphorus combined with chlorine to produce 27.8 g of a white solid compound. what is the empirical
Umnica [9.8K]

Grams of Phosphorus = 4.14 grams 
Grams of white compound = 27.8 grams 
Grams of Chlorine would be = 27.8 - 4.14 = 23.66 grams
 Calculating moles which would be grams / molar mass
 Molar mass of P = 30.97 grams / moles; Molar mass of Cl = 35.45 grams / moles
 Moles of Phosphorus = 4.14 grams / 30.97 grams / moles = 0.1337 moles
 Moles of Chlorine = 23.66 grams / 35.45 grams / moles = 0.6674 moles
 Calculating the ratios by dividing with the small entity
 P = 0.1337 moles / 0.1337 moles = 1
 Cl = 0.6674 moles / 0.1337 moles = 5 
So the empirical formula would be PCl5

Which of the following can be described as genetic material that describes the cell?
skelet666 [1.2K]
The best answer to this question is DNA. DNA holds the genetic makeup of the body in each individual cell. RNA is part of DNA. The nucleus holds the DNA. Ribosomes turn RNA into protein. That is why the answer cannot be RNA, ribosomes, or the nucleus.
