CAN SOMEONE DO A CER ON WHY TREES MASS COMES FROM AIR

Biology
1 answer:
Tems11 [23]3 years ago
3 0

The vast majority of a tree's carbon comes from the air, which averages 0.03-0.04% by volume (300-400 ppmv) CO2. This is fixed through photosynthesis and eventually stored as glucose which the plant can then use for its metabolism.

How many daughter cells result from a parent cell in meiosis?
masha68 [24]

Answer:4 haploid daughter cells

Explanation:

Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. During reproduction, when the sperm and egg unite to form a single cell, the number of chromosomes is restored in the offspring.

Meiosis begins with a parent cell that is diploid, meaning it has two copies of each chromosome. The parent cell undergoes one round of DNA replication followed by two separate cycles of nuclear division. The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell.

Which of the following is NOT a mechanism used to temporally regulate the activity of maturation-promoting factor (MPF)?
slavikrds [6]

Answer:

C. glycosylation

Explanation:

The maturation-promoting factor (MPF) is a cell cycle checkpoint that stimulates the passage from G2 (prophase) to M phase (metaphase). MPF also determines that DNA replication during the S (synthesis) phase did not produce any mutations. MPF is inactivated by kinase phosphorylation and activated by specific phosphatases capable of dephosphorylating this protein. On the other hand, glycosylation is a posttranslational modification where a carbohydrate (i.e., a glycan) is added to a functional group of another molecule. Many proteins undergo glycosylation, thereby playing a critical role in regulating protein function.

As a project manager, sarah uses many different tools and techniques. which tool or technique should sarah use to hold a kickoff
Rus_ich [418]

Answer: teleconferencing

Explanation:

    Using peer-to-peer collaboration will not work if the members work at many different locations.

    While instant messaging may work, it can be hard to have a meeting this way.

     Templates do not apply to this situation.

     This leaves us with the answer of "teleconferencing" as you can have a meeting with people online, even when they are far apart.
