The cell-mediated immunity differs from humoral immunity in that they respond differently to invaders. The cell mediated immunity is a type of immune response that dose not involve antibodies, however it involves the activation of phagocytes, antigen specific cytotoxic T-lymphocytes, and the release of various cytokines in response to a foreign body (antigen). The humoral immune response is mediated by antibody molecules that are secreted by plasma cells.

Since sun can filter to the bottom of a pond because it is shallower than a lake, what would you find at the bottom of a pond th
liberstina [14]

Answer:

The correct answer is - C. Plants.

Explanation:

As we know and also given that the pond is usually smaller and shallower than a lake. Due to this reason, ponds have plants growing on the bottom of them from one side to the other as they get enough light as there is only the photic zone in ponds.

In lakes, there are various zones present and the lakes are deep and big to the ponds and the bottom of the lakes did not get sunlight. Plants require sunlight to grow and lakes are usually too deep to get the sunlight for plants to grow on the bottom.

In the citric acid cycle, the enzyme succinate dehydrogenase catalyzes a reversible reaction using FAD/FADH2 as an oxidizing/red
Aliun [14]

The statement which best explains how the redox component of this reaction contributes to the reaction's ability to be reversible under cellular conditions is; <em>Choice D: The change in the biochemical standard reduction potential is small.</em>

Discussion:

A reversible process is one in which the system and environment can be restored to exactly the same initial states that they were in prior to when the process occurred, if we go backward along the path of the process.

  • However, the necessary condition for a reversible process is therefore the quasi-static requirement.

  • The quasi-static requirement in this case is that the change in the biochemical standard reduction potential is small.

A particularly long radio wave has a wavelength of 1.5 x 10^9 meters. What is the frequency of this radio wave?
Phoenix [80]

Answer:

0.2Hz

Explanation:

The wavelength of a radiowave can be calculated this;

λ = v/f

Where;

λ = Wavelength (m)

v = speed (m/s)

f = frequency (Hz)

Based on the information provided in this question, λ = 1.5 x 10^9 meters, c = 3 × 10^8m/s, f = ?

Hence, using λ = v/f

f = v/λ

f = 3 × 10^8 ÷ 1.5 x 10^9

f = 2 × 10^(8-9)

f = 2 × 10^-1

f = 0.2Hz
