A student wanted to see if covering a leaf in foil would stop it from producing starch. Why should the student put the plant in a dark cupboard for 48 hours before returning it to the light and starting the experiment?

1. To make the results reliable
2. So that the plant would photosynthesise faster when returned to the light
3. So that any starch already in the leaf was used up by the plant
4. He did that simply

Answers

Answer 1

Answer:

4.) He did that simply

Explanation:

I'm just guessing it's 1 because the other answers don't seem reasonable

Answer 2

Answer:

Putting the plant in dark for 48 hours would stop the process of photosynthesis as light is required for it. Photosynthesis produces organic sugars which are stored in form of starch in plants. The absence of photosynthesis would lead to the consumption of all stored starch making the leaf starchless. The correct answer is option D.

what 2 parts of a chlorplast does photosynthesis take place

Answers

Answer:

The Grana and The Stroma.

Explanation:

I hope this helps u! :D

Answer: Photosynthesis occurs in geranium and stroma parts of chloroplast.

Explanation:

Chloroplast is an organelle covered by double membrane. Inner membrane is folded inside to form lamellae. The lamellae are stacked one above the other to from geranium. There are many grana in a single chloroplast. The remaining matrix consisting of cytoplasm is termed stroma. In the stroma are present other cytoplasmic inclusions like fragments of DNA and ribosome, etc.

Photosynthesis occurs in 2 steps:

1. Hill's reaction or Light reaction: It occurs in presence of light in geranium part of chloroplast.

2. Dark reaction or Blackmann's reaction: It does not require light directly, occurring irrespective of presence or absence of light. However, it is dependent upon the end products of light reaction. it occurs in stroma part of chloroplast.

The answer may be supplemented by viewing the diagram of electron microscopic structure of chloroplast from any book one may have, covering photosynthesis.

By viewing the enzyme diagram and its target molecule, we can infer that a mutation might affect the interaction between the enzyme and target because it may change the shape of the enzyme and consequently inhibit its function.

What is a genetic mutation?

A genetic mutation can be defined as a permanent alteration in the DNA sequence that makes up a gene, which affects the production of a protein and may have a wide range of effects on the function of a cell.

Therefore, with this data, we can see that a genetic mutation may modify the protein and thus affect the reaction.

Answers

It's 13 because at first you have 14 from 4 females emigrating then 2 leave giving you 12, then 2 are born giving you 14 again but then 1 dies giving you 13

From the original number of 10 gorillas, there are now 9 gorillas in this population. The correct option is B. After 4 females emigrated, 2 immigrated, 2 gorillas were borned, and 1 male died, there are 9 gorilas.

Available data:

10 gorillas in the original group4 females emigrate2 females immigrate2 gorillas are born1 gorilla dies.

So, from the original group, 4 individuals left, so

10 - 4 = 6 individuals

To the group of 6 gorillas, 2 individuals were added, so

6 + 2 = 8

In the group of 8 gorillas, 2 babies are borned,

8 + 2 = 10

And one individual died,

10 - 1 = 9.

The remaining number of individuals in this population is 9. Option B
