Answer:
It ensures that sexually reproduced offspring have the correct amount of chromosomes when born, this ensures that disorders such as down syndrome don't occur. It also makes genetic variation possible, by way of genetic recombination, this is so that siblings don't look exactly the same, disregarding twins.
Explanation:
Meiosis is such a critical process in the inheritance of traits, and meiosis is important because it ensures that each daughter cell receives the correct number of chromosomes from the parent cells.
What is the significance of the inheritance of traits?Inheritance of traits allows for the transfer of beneficial traits from one generation to the next, allowing populations to adapt to changing environmental conditions, and the study of inheritance of traits can provide insight into the underlying genetic causes of diseases. The understanding of the traits helps in the improvement of agriculture and in other fields of biology.
Hence, meiosis is such a critical process in the inheritance of traits, and meiosis is important because it ensures that each daughter cell receives the correct number of chromosomes from the parent cells.

Which of the following occur during interphase? Select all that apply.
A) cells prepare for cell division
B) chromosomes divide
C) cytoplasm divides
D) cells grow rapidly
E) chromosomes replicate
Cells grow rapidly and hromosomes replicate are occurs during interphase.
What do you mean by interphase?Interphase is the portion of the cell cycle that is not accompanied by visible changes under the microscope, and includes the G1, S and G2 phases. During interphase, the cell grows, replicates its DNA and prepares for mitosis.
A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.
Interphase is the longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis. During mitosis, chromosomes will align, separate, and move into new daughter cells.

How is phosphorus processed by the wetland?
I
Explanation:
Phosphorus, organic nitrogen and some metals ( iron or aluminium) usually attached to sediment and are carried by runoff to wet land. By holding water, a wetland allows sediment and large particles ti settle on the wetland bottom. The root systems of wetland plants then absorb nutrients from the sediment.
is Sedimentary rock. tilting, erosion or folding
Answer:
Tilting - Rock strata always form horizontally, so anything not horizontal has been acted upon. ... Folding - If the rocks are bent, they have been folded. Faulting - If there is a break and movement within the rocks, this is a fault.
Explanation:
Answer
I'd have to say it's Tilting.
Explanation:
This question needs to be more specific since the form of the rock can form differently which ultimately alters this answer to most likely folding, but I'd have to say my best answer would be tilting. Hope this works!

Trees, such as those in the deciduous forest, are very important to the environment. If the number of trees on earth continues to decrease significantly, what might be the result? (Site 1)
Answer:
more carbon dioxide would build up without the tress to recycle it and many animals would lose their habitats
Answer:
Animals will begin to migrate towards residential areas if the number of trees on the planet continues to decline, as their natural habitat would be destroyed. There are numerous plant species that can be used as a source of medicine for disease prevention and treatment. Trees provide a significant amount of oxygen to the environment. Some deciduous forest trees grow near rivers, preventing soil erosion by attaching dirt to the plant's roots. Cottonwood, mountain ash, and fruit trees are commercially important trees. If there is a considerable reduction in the quantity of trees, all of the above benefits of trees will be lost.
