Substances can enter and exit the cell through the membrane through passive or active transport. The processes of endocytosis and exocytosis ensure, respectively, the entry and exit of macromolecules and other particles.

<h3>In which two ways do substances cross the membrane?</h3>

The selective passage of substances across the membrane occurs in two different ways:

  • active transport, when it involves the use of energy.
  • passive transport, when it does not involve the use of ATP.

With this information, we can conclude that substances can enter and exit the cell through the membrane through passive or active transport. The processes of endocytosis and exocytosis ensure, respectively, the entry and exit of macromolecules and other particles.

3. If all the producers in the above food web contain 40,000 Kcal of energy, how much
Artist 52 [7]

Answer:

The answer is only about 40

Explanation:

Whenever something is consumed, only about 10% of the energy is consumed. So when a primary consumer eats the producer, they will get about 4,000 kcal. Then the secondary consumer will get about 400. Finally, the tertiary consumer will only get about 40. Basically, just multiple the original number by 0.1 for every time it goes through consumption.

Which is not evidence for the endosymbiotic origins of mitochondria and chloroplasts?
Zolol [24]

Mitochondria and chloroplast have similar DNA, which is not evidence for the endosymbiotic origins of mitochondria and chloroplasts.

According to the endosymbiotic theory, a chloroplast and a mitochondria were the independent prokaryotes. Both can be ingested by a large prokaryote and resist digestion. As a result, they continued as endosymbionts and eventually lost some of their autonomic properties. They divide by binary fission, have their own genetic material, possess 70s ribosomes, and Both include their own transcriptional and translational machinery.

Therefore, considering endosymbiotic origin theory, Both Mitochondria and chloroplast have similar DNA is not a piece of evidence.
