Plants can be identified by specialized structures in their cells, let's take a look at an example of a specialized plant cell,

chloroplasts:
a) What part of the plant would you expect to have the highest number of chloroplasts (leaf, stem, roots)? Why?
b) Which months would you expect to find the highest number of chloroplasts in a given plant? Why?

<h2>a)   leaf have highest number of chloroplasts because they are in direct contact with the environment an they absorb sunlight.</h2><h2>b)    in march, april and may we expect to find the highest number of chloroplasts in a plant because there is an optimum amount of sunlight and more leaves as its spring in these months, number of leafs increases in plants</h2><h2></h2>

What is an example of the effect of environmental factors on cell differentiation?​
yanalaym [24]

Answer:

Environmental factors can alter gene expression, cell signalling and cell differentiation.

Explanation:

  • Environmental factors can change, stop or disrupt the process of cell signalling and gene expression in organisms.
  • The environmental factors are drugs, chemicals, temperature, etc.
  • With the effect of environmental factors, the organism will try to adapt to the environment by changing the internal process.
  • In case of adaptation, some organism may survive to the changing environment but there is a risk of exhibiting defects and in some case, the result can be death.

Helen [10]

Answer : Option B) Tedium.

Explanation : As it is clearly observed from Martin's workout schedule that it is lacking in intensity or progression, which is a subjective matter and basically depends upon the base level of strength and fitness that his body is capable of.

With the shared schedule of Martin's, it shows that he is trying to avoid tedium,which is tedious exercises for his body; as he has included many variety of different activities into his weekly routine but which lacks on tedium exercises.

What is the relationship between proto-oncogenes and oncogenes?
SCORPION-xisa [38]

Answer:

Oncogenes result from a mutation in  proto-oncogenes.

Explanation:

  • Protooncogenes control the growth and division of cells.
  • The proteins encoded by proto-oncogenes include growth factors, growth factor receptors, transcription factors and signal transducers.
  • They contribute to the transformation process by driving cell proliferation or reducing sensitivity to cell death.
  • Several types of genetic and epigenetic changes convert these proto-oncogenes to oncogenes.
  • Oncogenes arise due to the changes that increases the expression of proto-oncogenes .
  • Oncogenes are one of the causes of cancers.

A proto-oncogenes can turn into oncogene by following ways:

  • A point mutation  such as deletion, insertion and substitution  in the proto-oncogene can lead to formation of oncogenes.
  • Chromosomal translocation may result in activation of proto-oncogene as seen in Burkitt's lymphoma.
  • Insertion of a mobile genetic material such as retrovirus changes the gene expression, but leaves their coding sequence intact.
  • Activation of proto-oncogene can also occur from reduplication and amplification of DNA sequence.
