Answer:

Down syndrome is a congenital condition characterized by a distinctive pattern of physical characteristics including a flattened skull, pronounced folds of skin in the inner corners of the eyes, a large tongue, and short stature, and by some degree of limitation of intellectual ability and social and practical skills. It usually arises from a defect involving chromosome 21, usually an extra copy.

Answer:

According to the diagram, what is occurring in step 7 is cytokinesis, with the separation of two daughter cells, following cell division.

Explanation:

Cytokinesis is a process that occurs at the end of mitosis or meiosis, being the final step of cell division. This mechanism allows the <u>separation of the two daughter cells</u>, with equal distribution of cytoplasm and formation of cell membrane, differentiating into two independent cells.

In the diagram it can be observed (step 7) that after the division process —in yellow— two arrows pointing to two cells are evident, which implies the process of cytokinesis.

Prior to the cytokinesis process, karyokinesis occurs, which is the separation of nuclei and formation of the nuclear membrane.

In animal cells, karyocinesis occurs by the effect of a ring of actin and myosin that helps to force the separation. In the plant cell, the fragmoplast is formed, a septum that induces the separation of the daughter cells.

The other options are not correct because:

  • <u><em>Cell growth</em></u><em> occurs in G1 phase.</em>
  • <u><em>Cell preparation</em></u><em> occurs in interphase.</em>
  • <u><em>DNA replication</em></u><em> occurs in S phase.</em>
  • <u><em>Mitosis</em></u><em> is represented in yellow, and involves 4 phases.</em>

Sara and Juan conducted an experiment to test which soil would be BEST for growing plants.
pantera1 [17]

Answer:

A. Type of soil

Explanation:

A control experiment is the one that is used to checkmate the real experiment.

In this case, the fourth jar that contains the mixture of all the types of the soil is considered as the control experiment.

In a nutshell, it should be generally understood here that the type of soil serves as the control for the experiment.

Yes! We can see which are dominant!

In this first generation progeny, we see that stripes are dominant and spots are recessive. And white bodies are dominant over orange!
