Answer:

They can perform photosynthesis.

Explanation:

Autotrophs are organisms that can produce their own food, and heterotrophs are organisms that feed on other organisms. This means that the ameba and paramecium can eat only other microorganisms.

The euglena is not limited to this. Hypothetically speaking, if there were no other microorganisms around it (which is unlikely), the euglena would not die as long as it is exposed to sunlight. Thanks to chloroplasts, organelles that contain chlorophyll, it can perform photosynthesis - a process in which, with the help of sunlight, carbon dioxide, minerals, and water are used to synthesize food.

Answer:

Hope it helps u

Explanation:

They do not get infected with tetanus because they have already been vaccinated which means there are white blood cells and antibodies ready to fight tetanus.

Their immune system is safe because the antibodies won’t let them feel sick.

erastovalidia [21]

Explanation:

-The increased light intensity increased the rate of photosynthesis.

Photosynthesis produces glucose and O2 from inorganic CO2, light energy and water. Since photosynthesis is rate limited, the rate of energy intake can be increased in order to speed up photosynthesis, by speeding up photolysis.

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

These end products, namely O2 and glucose are then used in respiration...

C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≈38 ATP

The CO2 and H2O produced as waste in respiration can then be incorporated at the beginning of photosynthesis. Thus the reactions are cyclic- they feed into each other.

Further Explanation:

Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and carbon dioxide while oxygen is released. This occurs in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. This occurs in the thykaloids, where pigment molecules like chlorophyll reside.

Occuring in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II.

Respiration and photorespiration both utilize oxygen for;

the production of ATP via the oxidization of pyruvate;
and the oxygenation of the molecule Ribulose 1,5-bisphosphate (RuBP), an organic molecule also used in photosynthesis, to form 3-PGA + phosphoglycolic acid,

∴ the rate of CO2 usage for photosynthesis where O2 is produced, outpaces the rate of O2 use in respiration and photorespiration.

What does the Teacher's Pet Video: Mitosis and Meiosis give as the main reason for the

postnew [5]

Answer:

The main reason for the production of haploid cells during meiosis is because the two haploid cells will fuse together to make a new genetically different diploid cell that will form the offspring.

Explanation:

In the context of sexual reproduction, meiosis is the process of cell division by which gametogenesis occurs. In this process, diploid cells are used to obtain haploid cells, called gametes.

The reduction of the chromosomal charge that occurs in meiosis is aimed at producing haploid cells —with half of the crosmosomes of a species— so that <u>when the parents' gametes join, they form a diploide cell</u> called zygote.

The zygote is the starting point for the development of a new individual, part of the offspring.
