1) Plant and animal cells are both categorized the same as prokaryotes or eukaryotes based on the presence of a particular membrane-bound organelle – the nucleus, bounded by the nuclear membrane.  

Explanation:

Prokaryotic cells are distinctive by the lack of a definitive nuclear structure or nucleus. Eukaryotic cells have a definitive nucleus with a nucleolus and DNA strands and stores the genetic information or the genes which are encased inside the nuclear envelope or membrane. Prokaryotic cells have their DNA in their cytoplasm since they lack a nucleus.

2) The organelles/structures that are found only within plant cells are chloroplasts and central vacuole.  

Chloroplasts are exclusively found only in plants. The chloroplasts contain the chlorophyll, the green pigment which helps the plants to absorb solar or light energy trapped from the sun to carry out photosynthesis.  

The central vacuole, the largest organelle, membrane-enclosed sac filled with fluid called cell sap. The central vacuole provides basic support and structure, maintain cell pressure, store reserve food and waste materials, and contains enzymes which aid various cellular activities.

All of the following are major functions of proteins except 1.control of biochemical reactions. 2.support for organs or tissues.
Galina-37 [17]

Answer:

<h2>5.storage of energy</h2>

Explanation:

  • Proteins are important biomolecules that are a type of macromolecule.
  • This macromolecule is made up of a monomer that is called amino acid.
  • There are many functions of the protein molecules in living organisms.
  • They play an important role as bodybuilding molecules, as enzymes, as transporter molecules, and many more.
  • Most of the enzymes are made up of the protein molecules and regulate the metabolic process of the living organisms.
  • Certain proteins are present in the plasma membrane of the cells and play an important role in the transport of the substances across the cells, recognition of certain foreign particles, and some other functions.
  • They also play an important role in the immune system.
  • The main storage molecules of energy are carbohydrates and fats so storage of energy is not considered as the major function of the proteins because they do not involve as carbohydrates and fats.

Which cell type divides fastest? (in order)
11Alexandr11 [23.1K]

Answer:

<u>Basal cells</u>

Basal cells divide faster than needed to replenish the cells being shed, and with each division both of the two newly formed cells will often retain the capacity to divide, leading to an increased number of dividing cells.

Check all statements below that are true
victus00 [196]

Answer:

Statements thar are true:

Some  organisms have phenotypes that make them better  increase chances of reproduction.

Natural selection continues to occur even today

Phenotypes found In the most successful members of a species become the most prevalent after  several generations.

Explanation:

It is not true that all organisms must compete for survival, sometimes the conditions are good and there is enough food or good climate conditions and that makes no need of competition an increase in the individuals of the species.

Animals undergo natural selection, this is a random natural phenomenon that can make plants and animals adapt better or worse to the enviromental conditions. This cause that the beneficiaries can adapt, survive and reproduce and became the most prevalent after generations.

Mutations are not phenomen that occur because the living being needs it, but rather they are phenomenon that occur at random at any time and determine the possibility of survival.

A decrease in food availability will do the contrary, decrease the variation in a population because it makes that only those who manage to adapt to eat another food survive, for example.

If a cell lacked peroxisomes, what vital process would not occur?
mr Goodwill [35]

Answer;

Neutralization of free radicals

Explanation;

-Peroxisomes are small vesicles found around the cell. They have a single membrane that contains digestive enzymes for breaking down toxic materials in the cell. They differ from lysosomes in the type of enzyme they hold. Peroxisomes hold on to enzymes that require oxygen (oxidative enzymes).

-The oxidative enzymes that break down fatty acids and amino acids, resulting in, among other things, the production of the toxic substance, hydrogen peroxide.
