Microbes vary in their tolerance of and requirements for oxygen. While obligate aerobes require oxygen to survive, other microbes can be killed by oxygen. H. pylori is considered a microaerophile as it grows best in a low oxygen environments, which is consistent with the environment in the stomach. What type(s) of microbe is/are likely to be found in the following locations of the body

Answers

Hi. Unfortunately, you did not submit the parts of the body to which the question refers, which makes it impossible for it to be answered. However, I will try to help you as best I can.

Microorganisms can be aerobic or anaerobic. Aerobics are those that survive in the presence of oxygen and therefore may be present in parts of the cup that have contact with oxygen. Anaerobic organisms are those that do not survive in the presence of oxygen and therefore can only be present in places in the body that do not come into contact with oxygen.

In this case, to answer your question, you need to identify if the parts of the body, that your question presents, come into contact with oxygen or not. This way it is possible to inform if the microorganisms that these parts of the body have are anaerobic or aerobic.

Name three different cells in a leaf that contain chloroplast. Please help​

Answers

The LEAF as a photosynthetic organ includes the following cells which contains CHLOROPLASTS

the palisade mesophyll

• the spongy mesophyll and

• the stomatal guard cells

The LEAFS are the main organ of photosynthesis. Photosynthesis is the process by which green plants manufacture their food in the presence of sunlight. This takes place in the CHLOROPLASTS of these plant. CHLOROPLASTS are structures that contains chlorophyll which traps in energy from the sunlight.

The mesophyll tissues are located between the upper and the lower epidermis of the leaf. The palisade mesophyll, which is found at the upper part, contains numerous CHLOROPLASTS and is the main site of photosynthesis in the leaf.

The spongy mesophyll is located at the lower part of the epidermis. They are irregularly arranged with air spaces between them which are linked to the stomatal openings. They also contain CHLOROPLASTS.

The stomatal guard cells are a pair of bean-shaped cells which controls the opening and closing of stomata. These cells contains CHLOROPLASTS which contributes to the movement of stomata.

Therefore the three different cells of the leaf that contains CHLOROPLASTS are the palisade mesophyll, the spongy mesophyll and the stomatal guard cells.

Which of the following statements is correct regarding engineering maize plants with a herbicide-resistance gene using Agrobacterium-mediated plant transformation?

a. The Ti-plasmid used for this experiment must contain tumor-inducing genes.
b. The herbicide-resistance gene is cloned into the T-DNA region of the Ti-plasmid.
c. The herbicide-resistance gene is cloned into a region outside of the T-DNA in the Ti-plasmid.
d. A guide RNA is used to transfer T-DNA from Agrobacterium to the plant cell.
e. The whole Ti-plasmid containing the herbicide-resistance gene is inserted into the maize genome after infection with Agrobacterium

Answers

Answer:

b. The herbicide-resistance gene is cloned into the T-DNA region of the Ti-plasmid.

Explanation:

Ti-plasmid has the ability to introduce part of its DNA (t-DNA) into the genome of host plants. This is very important for the relationship of genetic manipulation in maize plants, with the aim of inducing a gene that promotes herbicide resistance. In addition, T-DNA has many genes that code for the production of plant growth phytohormones, which is extremely important for the cloning process to work. In this case, we can assume that the correct answer for yours is the letter B.
