What are the two factors that affect the friction between two surfaces

BabaBlast [244]

Answer:

The two factors are:

• The kind/type of surface involved.

• The force that the surface are being pushed together.

Explanation:

Friction can be said to be the general term used to describe the force that one surface exert on another when they rub against each other.

When the surface is partially not smooth or totally rough, a greater force is been needed to move one surface past the other.

The weight of the can also significantly be a key factor. This is where the need to friction reduction come to play a role; and need for friction reducers like lubricant, rollers etc helps.

A woman produces an egg with 24 chromosomes, including 2 copies of chromosome 21. If the egg is fertilized by a normal sperm, th

Zielflug [23.3K]

Answer:

Explanation:

We all know that gametes like egg cell and sperm have haploid set of chromosomes but here as per this question she has produced 2 copies of chromosome 21. For the sake of maintaining haploidy, she was supposed to have only a single copy of chromosome 21 as a result of which her egg cell was supposed to have 23 chromosomes not 24.

But, this is a case of non dis-junction. Also, in a normal sperm there are no such copies of any chromosome i.e. there is a haploid set of chromosomes. It means that sperm must be having only 23 chromosomes. So we can easily infer that when the egg cell and sperm will fuse, the zygote will have 47 chromosomes (24 from egg cell and 23 from sperm).
