Openings between _____ cells create pores in the leaf epidermis that play a critical role in photosynthesis by allowing diffusion of atmospheric CO2 into a leaf's interior.

Answers

Answer 1

Answer:

Answer:

Guard

Explanation:

The opening between guard (pores) cells is known as stomata. The stomata helps in diffusion of atmospheric CO2 into leaf's interior and also involved in loss of water by plant leaves through transpiration. The opening and closing of stomata is controlled by guard cells.

Guard cells control the opening and closing of stomata by becoming turgid or flaccid because of potassium ions. The water potential decreases by increasing the solute concentration and water always flow from higher potential to lower potential. Remember maximum water potential is zero.

When potassium ions concentration increases inside the guard cells, water follow the potassium ions and guard cells become turgid which cause the opening of stomata. On the other side when the potassium ions concentration decreases inside the guard cells the water leaves the guard cells and guard cells become flaccid causing closing of stomata.

Thank you for any ideas contributed, it is very much appreciated! :3 ♥ 12 Points+Brainliest for the best answer

developed a way to protect their foliage. Instead of flat leaves, pine trees have needles. These needles are the key to the Winter survival of the pine tree. Needles cut evaporation sotrees can save water!
Cacti have sines instead of leaves because they help protect them from getting eaten and they don't need leaves because they store water inside themselves.
They both have adapteations to help them servive in very harsh conditions. Cacti use their adaptations to survive in scourching heat and pine trees can servive in freezing cold.

What is the name of the process in which an organism makes a new organism? A.
mutation

B.
fertilization

C.
variation

D.
reproduction

Answers

Reproduction is the process in which an organism makes a new organism. Thus, the correct option is D.

What is Reproduction?

Reproduction is the process of production of new organism. There are two main types of reproduction including sexual and asexual reproduction.

In sexual reproduction, an organism combines the genetic information from each of the two parents and is genetically unique from both the parents. In asexual reproduction, one parent copies itself to form a genetically identical offspring called as clone.

Reproduction ensures the continuity of the species and keeps the species from becoming extinct. It plays a role in evolution of the species as it creates variations through genetic recombination.

Therefore, the correct option is D.

your answer is appositive phrase.

23. How many total chromosomes are in a germ cell in the testis of this organism that is in Metaphase of Meiosis II?

Answers

There are 46 chromosomes in each cell at metaphase II in meiosis in humans. Normal human body cells each have 46 chromosomes. Prior to meiosis, the DNA replicates and each cell gets 92 chromosomes.

Final answer:

A germ cell in the testis in Metaphase II of Meiosis has 23 chromosomes.

Explanation:

In Metaphase II of Meiosis, the chromosomes line up at the equator of the cell and are ready to be separated into two daughter cells. Each daughter cell will receive half the number of chromosomes as the parent cell. In humans, the diploid number of chromosomes in a somatic cell is 46, while the haploid number of chromosomes in a germ cell is 23.

Therefore, in Metaphase II of Meiosis, a germ cell in the testis would have 23 chromosomes.
