What is an Obligate anaerobe? How do obligate anaerobes, like the bacteria C. Botulinum, get energy ?

Answers

Answer 1

Answer:

See the answer below

Explanation:

Obligate anaerobes are microbes that can only survive in oxygen-deficient environments. They are killed by the normal atmospheric level of oxygen and will only thrive in environments whose oxygen levels are lower than that of normal atmospheric level.

Obligate bacteria such as Clostridium botulinum obtain their energy through anaerobic respiration processes such as fermentation and anaerobic respiration. During this process of fermentation, the lactic acid pathway is mostly used but other fermentation pathways such as propionic acid, mixed acid, acetogenesis, and methanogenesis pathways can be used.

Explanation:

A scientist hypothesized that oxygen atoms from both carbon dioxide and water are used to make glucose during photosynthesis. However, experimental results using oxygen isotopes showed that all of the oxygen from the water ended up in the oxygen molecules that were produced. None of the oxygen from water was found in glucose.

What should the scientist do to best gain scientific understanding of this topic?

a. Analyze the results, and change the experimental methods to retest the hypotheses in a different way.
b. Discard the faulty results that do not support the original hypothesis, and repeat the experiment using the same methods.
c. Analyze the procedural errors that took place in the experiment, and summarize these in a conclusion statement.
d. Repeat the experiment and adjust new data to support the original hypothesis.

Annette has her thyroid gland removed because of a malignant tumor. She takes synthetic thyroid hormone to replace the thyroxine that her thyroid gland would have produced, but she is worried about her blood calcium level since she has lost her source of calcitonin. Does she need to worry about this problem

Answers

Answer:

She doesn't need to worry if her parathyroid glands are working.

Explanation:

Although Annette has to worry about the impacts of thyroid gland removal and synthetic thyroid hormone intake, the calcium levels in her body need not be a concern as long as her parathyroid glands are functioning normally.

This is because the parathyroid glands are responsible for regulating calcium levels in the blood, through the production of parathyroid hormones or parathormone.

Mark Brainliest please

Poikilothermic animals include types of vertebrate animals, specifically some fish, amphibians, and reptiles, as well as many invertebrate animals.

Reptiles are cold-blooded, or ectothermic, animals. This means that they cannot produce heat in their own bodies, and have to rely on their surroundings to keep warm. This is why most reptiles are found in hot or warm climates. Reptiles often bask in the sun to get warm.

Both reptiles and amphibians are poikilothermic, which means that they cannot regulate their own body temperatures internally as birds and mammals do.

) An allosteric interaction between a ligand and a protein is one in which: (3 pts) A) binding of a molecule to a binding site affects binding of additional molecules to the same site. B) binding of a molecule to a binding site affects binding properties of another site on the protein. C) binding of the ligand to the protein is covalent. D) multiple molecules of the same ligand can bind to the same binding site. E) two different ligands can bind to the same binding site.

Answers

Answer:

B) binding of a molecule to a binding site affects the binding properties of another site on the protein.

Explanation:

In an allosteric interaction between a protein and a ligand, the ligand binds to a site in the protein. As a result, there is a change in the properties of other active sites on the protein. These active-site changes may or may not allow the protein to bind to other molecules. There is a change in the protein that affects the affinity of the active site for other molecules. The affinity on the active site increases if the protein binds to an activator and decreases if the protein binds to an inhibitor molecule.
