Answer:

Digestion is important for breaking down food so that it can be processed and used for nutrients your body requires for survival. Digestion is one of the most important bodily functions because it's the main contributor to the creation of energy which goes into everything you do on a molecular and physical level, ranging from walking to and from your fridge at 2 in the morning, to repairing your cells and growing new ones.

Answer:

Digestion is important for breaking down food into nutrients, which the body uses for energy, growth, and cell repair. Food and drink must be changed into smaller molecules of nutrients before the blood absorbs them and carries them to cells throughout the body. The body breaks down nutrients from food and drink into carbohydrates, protein, fats, and vitamins.

In the alteration of generations life cycle the spore undergoes mitosis to become a A) gametophyte B) sproohyte C) spore D) game

Eva8 [605]

A mature sporophyte produces spores by meiosis, a process which reduces the number of chromosomes to half, from 2n to n. Because meiosis is a key step in the alternation of generations, it is likely that meiosis has a fundamental adaptive function. The nature of this function is still unresolved (see Meiosis), but the two main ideas are that meiosis is adaptive because it facilitates repair of DNA damages and/or that it generates genetic variation. The haploid spores germinate and grow into a haploid gametophyte. At maturity, the gametophyte produces gametes by mitosis, which does not alter the number of chromosomes. Two gametes (originating from different organisms of the same species or from the same organism) fuse to produce a zygote, which develops into a diploid sporophyte.

The net primary production of a pine forest on a lava flow on Mount Fuji is about 165,000 kcal/m2/yr, and the plant respiration

IceJOKER [234]

Answer:

The total amount of energy transferred during photosynthesis for this ecosystem equals 260,000 kcal/m2/yr.

Explanation:

To answer this question, we need to know that

gross primary productivity (GPP) = energy captured and converted into chemical energy during photosynthesis

net primary productivity (NPP) = difference between GPP and respiration rate

So, to calculate GPP we need to sum NPP to Respiration rate. This if,

NPP = 165,000 kcal/m2/yr

R = 95,000 kcal/m2/yr

NPP = GPP – Respiration

Then,

GPP = NPP + R

GPP = 165,000 kcal/m2/yr + 95,000 kcal/m2/yr

GPP = 260,000 kcal/m2/yr
