Answer:
Option A, accumulate sulfur as intracellular granules.
Explanation:
Purple sulfur bacteria belong to the group of Proteobacteria. These probacterias are anaerobic in nature and yet are able to photosynthesise. They are usually found in water environments such as hot springs, stagnant water etc. They use sulphur (either in the form of sulfide, or thiosulfate) as an electron donor in their photosynthetic activity to oxidise sulfur thereby producing granules of elemental sulfur.
while filamentous sulfur oxidizers use nitrate instead of oxygen to oxidize sulfide thereby producing granules.
Hence, option A is correct.
Answer:
Maintaining a rich variety of genetic material that can lead to discoveries useful for humans can be ensured by preserving biodiversity.
Explanation:
Options for this question are:
- <em>Preserving biodiversity
.</em>
- <em>Increasing cloning
.</em>
- <em>Asexual reproduction
.</em>
- <em>Selective breeding.</em>
Biodiversity refers to the number of different living organisms that exist, and which are the product of evolution, those that have multiple ways of interacting, shaping life on the planet.
The human being is part of biodiversity, considered a natural heritage of the world and an element that provides balance to the biosphere.
An important characteristic of biodiversity is that it contains the different genetic information of each living being, each one of which is a functional element on which the maintenance of life on the planet depends, as well as the reservoir of the world's genetic potential, so it is necessary to guarantee its preservation.

An active transport is the process by which a substance is transported or transferred from one area to another using a chemical energy in the course.
<span>As oppose to passive transport, active transport’s key to its description uses energy to be able to transfer the said substance. This is important in a lot of aspects such as providing the needed elements or compounds in cellular activity.<span>

<span>Diffusion occurs because of the movement of molecules from the region of higher concentration to the region of lower concentration.
Omosis is the movement of water.
