Some antibiotics work by disrupting ATP production in bacteria. Which of the following will the bacteria lack when ATP production is disrupted?
A. genetic material for reproduction
B. energy to perform life processes
C. nucleic acids to make proteins
D. cytoplasm to diffuse oxygen

Answers

The answer to your question is D!!

When there is a lack of bacteria at the time when ATP production is disrupted so here the energy is performed. Hence the option b is correct.

Reason of lacking bacteria:

At the time when there is some kind of antibiotics work is done by disrupting ATP production in bacteria.

So the lacking of bacteria at the time when ATP production is disrupted so it is because of the energy to perform the life processes.

hence, the option b is correct.

Why are archaea in a different domain from bacteria?
A. They are multicellular, but bacteria are unicellular.
B. They are thought to have separate paths of evolutionary
development
C. They are able to perform endosymbiosis, but bacteria are not.
D. They have no similar characteristics.

Answers

Answer:B

Explanation:

Archaea is in a different domain from bacteria because they are thought to have separate paths of evolutionary development. Therefore, the correct statement is option B.

What are the differences between archaea and bacteria domains?

Archaea and bacteria are both prokaryotic organisms, but archaea are more closely related to eukaryotes than bacteria. Archaea have unique  lipid membrane and cell wall components that are different in composition than those found in bacteria.

These differences suggest that archaea and bacteria evolved to have separate paths of evolutionary development early in the history of life on Earth and then classified into Archaea and Bacteria domains.

Based on the phylogenetic tree constructed by researchers, the tree has classified life into three domains which are Archaea, Bacteria, and Eukarya These domains are based on their fundamental genetic and biochemical differences.

Therefore, archaea and bacteria are in a different domain because they followed separate paths of evolutionary development.

What might happen if the number of chromosomes within the cells did not change but new daughter cells were still made? (meiosis)

Answers

Answer:

No fertilization occurs.

Explanation:

No zygote is formed if the the number of chromosomes within the cells did not change or remain the same i.e. diploid because for the production of zygote, half number of chromosomes are required in both male and female sex cells or gametes. If the chromosomes are half in both gametes so they fuse with each other forming zygote having diploid cell so we can conclude that for the happening of fertilization process, half number of chromosomes in gametes is necessary if not, no fertilization occurs.

give an example of something that might stop a cell from checking things during the cell cycle

Answers

Answer:

A checkpoint is one of several points in the eukaryotic cell cycle at which the progression of a cell to the next stage in the cycle can be halted until conditions are favorable. ... The G2 checkpoint ensures all of the chromosomes have been replicated and that the replicated DNA is not damaged before cell enters mitosis.

A mutation in a tumor suppressor gene may stop a cell from checking things during the cell cycle.

Tumor suppressor genes are normally expressed genes that control the progression of a cell through the cell cycle.

These genes (tumor suppressor genes) act to repair mutations that occurred during DNA replication, slow down cell division, activate programmed cell death pathways (i.e., apoptotic pathways, etc).

For example, p53 is a tumor suppressor gene capable of controlling cell division rate by keeping cells from proliferating in an uncontrolled manner.

In consequence, mutations of the p53 gene are often observed in cancer cells that lost their ability to regulate the rate at which they grow.

In conclusion, a mutation in a tumor suppressor gene may stop a cell from checking things during the cell cycle.

What are living organisms?

The organism which can breathe, reproduce and have the ability to respond to an environment are some of the characteristics of a living organism.

Reproduction is the ability of an organism which gives similar kinds of organisms. Organisms grow and develop through cell division. Cell division is of two types mitosis and meiosis. Mitosis is an equational division.

The organism can respond to the environment. Mouse running away from the sound of an owl's wing is an ability to respond environment. Different organisms can obtain energy from food sources.
