Based on what you know about the regulation of cell growth, make a list of questions you would ask as you observe the cells.

Biology
1 answer:
sertanlavr [38]3 years ago
4 0

Answer:

1. What genes control the growth of cell growth?

2. What is the purpose of this regulation?

3. What happened when the cell growth is not regulated?

Explanation:

What genes control the growth of cell growth? What is the purpose of this regulation? What happened when the cell growth is not regulated?

Above are the questions which an observe would ask about regulation of cell growth. A number of genes such as oncogenes and tumor suppressor genes are involved in the regulation of cell growth and cell division. Regulation of cell growth process ensures that a cell's DNA which is dividing is copied properly as well as repair errors in the DNA. It also ensures that each daughter cell receives a complete set of chromosomes in order to gain healthy daughter cells.

Are microorganisms best suited for dry, warm environments?
gregori [183]

Answer:

The most significant effect of the microbes on earth is their ability to recycle the primary elements that make up all living systems, especially carbon, oxygen, and nitrogen (N). Primary production involves photosynthetic organisms which take up CO2 from the atmosphere and convert it to organic (cellular) material.

If the bald eagle was removed from this food web, what effect would this have on the population of the other species?
den301095 [7]

Answer:

C) The benthic invertebrates would decrease in population size because they are eaten by the sea ducks and the phytoplankton would increase in population size.

Explanation:

The benthic invertebrates are eaten by sea ducks. Sea ducks are eaten by bald eagles. If the bald eagle was removed, there would be more sea ducks because they will have no more predators. Since there are more sea ducks, they will need to eat more food, like benthic invertebrates. The benthic invertebrates would have a lower population because the sea ducks eat more of them.

Why not the other answers:

A) The bivalves would not increase in population size. Without the bald eagle preying on sea ducks, there would be more sea ducks, who need to eat more food, such as eating more bivalves.

The phytoplankton would not decrease. With sea ducks eating more food, more benthic invertebrates are eaten. There would be less benthic invertebrates to eat phytoplankton.

B) Tundra swans were never eaten by bald eagles. There is no arrow connecting them.

D) Wading birds were never eaten by ospreys. There is no arrow connecting them.

Consider the following family history: Bob has a genetic condition that affects his skin. Bob’s wife, Eleanor, has normal skin.
Damm [24]

Answer:

X-linked dominant

Explanation:

In this scenario,

It is caused by a X-linked dominant allele. Bob daughters would all have the same skin condition as Bob.

It will interest you to know that none of Bob sons would have the skin conditions as they have his Y chromosome instead

Which statement is true about a species living in a homogenous environment compared to a species living in a heterogeneous envir
Dovator [93]

Answer:

A species that lives in a heterogeneous environment is more likely to exhibit phenotypic plasticity.

Explanation:

Phenotypic plasticity might be understood as the ability of a genotype to produce different phenotypes in response to varying environmental conditions.

Phenotypic plasticity needs epigenetic mechanisms to occur, which involve the genotype and the environment interaction to produce adapted phenotypic changes.

Epigenetic mechanisms produce changes in the expression of the genes, with no need to alter the DNI nucleotides sequences.

A heterogeneous environment imposes variability on genotypes that interact with it, producing different phenotypes. These phenotypes will vary according to environmental conditions.

Gardeners understand that plants have specific pH requirements. Most plants thrive in soil with a pH that is slightly acidic, ne
nalin [4]
<span>In order to lower the PH to an appropriate level so that garden plants thrive,

the gardener should add a natural acid like pine needles or humus.


To add a base like calcium carbonate or limestone. Acids have a PH which is less than 7.

 If a base is added to an acid, the PH is raised. Adding humus will decrease the PH as it is also acidic. Adding fertilizer may help the plants, but it won't change the PH neither watering will.</span>
