Answer:
Light refracts whenever it travels at an angle into a substance with a different refractive index (optical density). This change of direction is caused by a change in speed. When light travels from air into water, it slows down, causing it to change direction slightly. This change of direction is called refraction

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.

A group of mountain gorillas has 10 members. How big is the group after 4 females emigrate, 2 females immigrate, 2 gorillas are born, and a male dies?(1 point)
1
9
13
7
Answers
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
