Alyssa's additional observation would be cell Y having a larger vacuole than cell X. The third option is the correct one.

<h3>Plant cell vs animal cell</h3>

From the observations, both cells are eukaryotic. This is because:

  • cell X has lysosomes which are only found in eukaryotic cells
  • cell Y has a nucleus which also peculiar to eukaryotic cells only

Lysosome houses digestive enzymes and is found mostly in animal cells. Only a few plant cells have lysosomes.

Thus, the lack of a lysosome means that cell Y is a plant cell while the presence means that cell X is an animal cell.

Generally, plant cells have larger vacuoles than animal cells.

Usimov [2.4K]

The question is incomplete as it does not have the options which are:

A. Phloem

B. Xylem

C. Apical meristem

D. Root cap

Answer:

The correct answer will be option- Root cap

Explanation:

The plant growth takes place not only above the surface but below the surface also in the roots. Roots continually grow to absorb more water and nutrients to support the growth of the plant.

The roots are protected by a layer of protective cells forming a structure called root cap below the root. The root cap protects the roots, secretes a substance which helps the growth of the root and the sense gravity.

In the given question since the roots are not able to grow therefore the damaged part will be the root cap.

Thus, the root cap is the correct answer.

What structure of the sarcomere shortens during muscle contraction?
LiRa [457]

Answer:

The Z lines and H- zone shortens during the muscle contraction.

Explanation:

Sarcomere is the area between the two Z lines. The Z- lines are present in the centre of I - band and H - zone is present in the A - band. The actin filaments which are thin filaments present in I- band and contracts, slide over the myosin filament during contraction.

The I - band, H- zones are became shortens as they are thin than the A- band. It is anisotropic band having thick myosin filaments. They are not flexible and remain in its constant shape during the muscle contraction.

After the muscle contraction, the A- band and the H- zone comes to their original shape. In other words, the sarcomere shortens and comes back during muscle contraction, and relaxation.

Integration mechanisms are: the mechanisms that enable each subunit to operate independently. the formal division of the organiz
Nataly_w [17]

Answer:

The correct answer is ''the mechanisms for coordinating subunits.''

Explanation:

Integration mechanisms are explicitly defined to coordinate subunits. In turn, are divided into structural and non-structural mechanisms. Structural integration mechanisms coordinate activities and are usually linked to specific management positions or bodies. The non-structural integration mechanisms, for their part, are characterized because they do not create organs or positions, but they constitute a relevant complement to the structural mechanisms, facilitating the organization of work. Informal integration mechanisms or those aimed at facilitating informal relationships are the simplest and easiest to use. Individuals face a certain situation and, spontaneously, communicate with each other. If no further coordination is required, informal mechanisms may be sufficient
