Answer:

Option-C

Explanation:

Apoptosis is a genetically controlled process taking place in the multicellular organisms which is marked with the self-destruction called or programmed cell death.

During apoptosis various physiological and morphological changes take place in the cell such as fragmentation of nuclear DNA, nucleus, shrinkage of cell and mRNA decay.

Since apoptotic cell undergoes cell death which is genetically controlled or programmed by the genes, therefore, apoptosis is known as the programmed cell death.

Thus, Option-C is the correct answer.

A cross country runner runs 8 km in 2 minutes. What is his speed?
oee [108]

The speed of the cross country runner is equal to 4 km/min.

<u>Given the following data:</u>

  • Distance = 8 km.
  • Time = 2 minutes.

To determine the speed of the cross country runner:

Speed can be defined as the distance covered by an individual per unit time and it can be measured in kilometer per minutes (km/min).

Mathematically, speed is given by the formula;

Speed = \frac{distance}{time}

Substituting the given parameters into the formula, we have;

Speed = \frac{8}{2}

Speed = 4 km/min.

Which of the following is not a cellular activity associated with microtubules?
sladkih [1.3K]

Answer:

A. maintenance of axons is not a cellular activity associated with microtubules.

Explanation:

Microtubules are hollow, bead-like, tiny tubular structure that helps cells maintain its shapes. Together with microfilaments and intermediate filaments, they form part of the cell's cytoskeleton. Microtubules also contributes to the cell movement or cytokinesis that includes muscle contractions in muscle cells. Microtubules also replicated chromosomes to opposite ends of a cell during cell division. Microtubules also contribute to the parts of the cell that help it move and are structural elements of cilia, centrioles and flagella. A bundle of microtubules makes up an axonemal structure of cilia and flagella.
