Forests exchange large amounts of CO2 and other gases with the atmosphere and store carbon, in various forms, in trees and soils. ... Much of the CO2 in the air above a forest is taken in by trees through the process of photosynthesis,where it becomes one of the building blocks fortree growth or energy for life. (i hope this can help you ):)
Answer: a) true
Explanation:
The goal of mitosis is to produce daughter cells that are genetically identical to the mother cell, without a single extra or missing chromosome. Meiosis, on the other hand, is only used for one purpose in the human body: the production of gametes or sex cells, i.e. sperm and eggs. The question is oriented to mitosis, <u>in which prior to this cell division, the cell duplicates its DNA</u> so that each daughter cell then inherits the genetic material. That is, the cell originally possesses 23 chromosomes, they duplicate to a total of 46 so that then each daughter cell receives 23.
The metaphase is the second phase of mitosis and meiosis that occurs after prophase where the envelope is lost and microtubules of the achromatic spindle (also called meiotic or mitotic) appear.
During metaphase, the chromosomes align themselves in the middle of the cell and this balanced midline spindle alignment is due to the equal and opposing forces generated by the kinetochore brothers.
Then during metaphase, the chromosomes will line up in the center of the cell to be separated and go each to a different daughter cell. But the moment they're found there, each orientation of chromosomes produces gametes with the same genetic information from each parent. <u>Because because there have been no changes or mutations in the chromosomes, they have duplicated and have the same genetic information.</u>
Answer:
Haemoglobin (Hb) is a protein present in red blood cells that transports oxygen and gives blood its dark/vivid red color. The amount of haemoglobin in the blood varies from person to person. Men's levels are often greater than women's. This is scientifically proven however, it is often but not all the time.
Mutations induced by UV.
The answer is option A.
They have a defect of their "curly gene," that's on the second chromosome. Having curled wings is a dominant mutation, this means that only one copy of the gene must be altered to supply the disorder. In reality, if both copies are mutated, the flies do not continue to exist.
Geneticists have lengthily counseled that mutations in insect pigment genes reason for modifications in the fly's brain because these pigments are crafted from dopamine, a chemical messenger that acts in the brain.
Thru those early experiments, he located that every one of the white-eyed flies being produced was a man, there were no white-eyed women in any respect. Inheritance of the white-eye trait might have a basis within the chromosomes, greater, in particular, the sex chromosomes.

Answer:
because the trigger for this is commonly encountered like a change in temperature
