Differentiate between cell mass and cell number

Biology
2 answers:
sergiy2304 [10]2 years ago
6 0

Answer:

Measurement (Count) of Cell Numbers:

1. Breed Method:

A known volume of microbial cell suspension (0.01 ml) is spread uniformly over a glass slide covering a specific area (1 sq. cm). The smear is then fixed by heating, stained, examined under oil immersion lens, and the cells are counted.

Customarily, cells in a few microscopic fields are counted because it is not possible to scan the entire area of smear. The counting of total number of cells is determined by calculating the total number of microscopic fields per one square cm. area of the smear.

Answer:

cell mass: The total mass of all the cellular elements in the body which constitute all the metabolically active tissue of the body

Cell number: The sequence of numbers or characters, that when dialed, connects to a particular cellular telephone

. Which graph best shows the general relationship
Andre45 [30]

The graph that best shows the general relationship between the temperature of a gas and the speed of the molecules in that gas is B.

<h3>What is kinetic energy?</h3>

Kinetic energy is the energy that an object or particle has as a result of its motion. When work transferring energy, is done on an object by applying a net force, the object accelerates and goes under kinetic energy.

The missing graphs are attached as image.

The average kinetic energy of gas molecules is

K=\frac{3}{2} k_{B}T

K∝T

So as per above equation, K-T graph is a straight line having a finite slope and passing through the origin.

Thus, option B is correct.

Predict how changing the grass population will affect the other organisms at first. Write + for “Increase” or – “Decrease” next
Afina-wow [57]

Answer: Here you go!

Explanation:

Doubling the amount of grass would definitely increase the rabbit population since there is more food/resources for it to produce. Since the food chain has a domino effect everything else would go up as well because of the increase of food/resources that will help sustain the population of all. so for the first line it would be increase for rabbit snake and hawk. Halving the amount of grass would effect the population of all animals as well. But in a more negative way. It would decrease because the rabbits wouldn't have enough food to produce and thrive. With the decline of rabbits less snakes will live because of the low amount of their main food source. Same with the eagles. So therefore it would be decrease in all the bottom lines.

The domestic cat genome contains 2.9×109 base pairs. The length of linker DNA in mammals is 50 base pairs. Approximately how man
IgorLugansk [536]

Answer:

Number of nucleosomes in 2.9 * 10^9bp is equal to 1.47 * 10^7

Explanation:

For wounding one nucleosome, total length of DNA required is equal to 146 bp

The length of  linker DNA in mammals is equal to 50 bp

Thus , the total length of DNA that confides between two nucleosome is equal to the sum of wounding length of DNA and the linker length

= 146 + 50\\= 196bp

Thus, in 196bp length of DNA, the total number of nucleosomes is equal to 1

Thus, number of nucleosomes in 2.9 * 10^9bp is equal to

\frac{2.9* 10^9}{196} \\1.47 * 10^7
