Answer:

C. are spirochaetes

Explanation:

Treponema and Borrelia are two genus belonging to the phylum Spirochaetes. It is a bacterial phylum consisting of unusual double membrane bacteria. This property makes the location of flagella different from other bacteria. Their flagella is located in periplasmic space between the inner and outer membrane which causes a twist motion. They reproduce by binary fission. They have chemotrophic mode of nutrition. Most of them are anaerobic and free living with some exceptions. Spirochaetes is a very diverse group of bacteria with variety in the niches, molecular characteristics and pathogenic capacity.

True or false? cell death normally does not occur unless there has been an injury to the cell.
Evgen [1.6K]

The statement 'cell death normally does not occur unless there has been an injury to the cell' is false.

A cell can be described as the basic building block of life. All living organisms are known to be made of cells.

There are various reasons that a cell might die. A cell might die when its function is over. A cell might also die for the formation of other structures in the body. For example, the formation of an outer layer of the skin requires dead cells. A cell might kill itself if it has no use or finds that it has been invaded by an antigen.

Hence, the statement that cell death occurs only due to injury is false as cell death can occur due to various other reasons.

steposvetlana [31]

395.2kcal

Explanation:

Given parameters:

Energy required to break one C-H bond = 98.8kcals

Unknown:

Energy required to break methane = ?

Solution:

The bond dissociation energy is the heat energy absorbed in breaking a covalent bond in the gas phase to its constituents elements.

  Solving

    CH₄ has 4 C-H bonds

To break 1 C-H bond, 98.8kcals of energy was used,

To break 4 of the bonds; 4 x 98.8kcals will be used = 395.2kcal
