The right option is; B.  

A virus that causes a common cold best describes a rhinovirus.

A rhinovirus is any of many common infectious viruses in humans and the primary cause of the common cold. Rhinoviruses can be transmitted directly from person to person through contaminated objects or through aerosols of respiratory droplets. Other diseases such as ear infections, sore throats and infections of the sinuses may also be caused by rhinoviruses.

antiseptic1488 [7]

Answer:

The answers are:

Cell Wall:

  1. Gives plant cell its shape
  2. Rigid

Cell Membrane:

  1. Acts like a skin.
  2. More selectively controls what goes in and out of cell.
  3. Is not rigid.

Explanation:

  • The question entails the structural and functional differences of the cell wall and cell membrane.
  • The cell wall is a rigid and strong layer that covers the outside of plant cells. It is absent in animal cells.
  • The cell wall is largely composed of cellulose, hemicellulose and pectin in plants and peptidoglycan in bacteria. The cell membrane, on the other hand, is comprised of a lipid bilayer.
  • The strong and complex network of cellulose renders the cell wall rigid; whereas, as it is made up of lipid bilayer, the cell membrane is flexible and elastic.
  • Unlike the cell membrane, which allows the movement of selective substances, the cell wall does not allow any substances to pass through.

What is homologous chromosomes?​
Yanka [14]

Explanation:

Homologous chromosomes are two pieces of DNA within a diploid organism which carry the same genes, one from each parental source.

In simpler terms, both of your parents provide a complete genome. Each parent provides the same 23 chromosomes, which encode the same genes. So, our cells carry 46 total chromosomes, in two copies. However, each homologous chromosome can provide a different version of each gene. Two versions of each gene create more variety, lower the detrimental effects of negative mutations, and generally stabilize a population.

I hope it's helpful!!
