Weight training has the biggest effect on __________.a. cardiac muscles
b. smooth muscles
c. involuntary muscles
d. skeletal muscles

Answers

d. skeletal muscles

Weight training has the biggest effect on the skeletal muscles. When a person is engaged in weight training activities the skeletal muscles are forced to move beyond their comfort zone because of the added weight. As a result, muscle fibers develop micro-tears. These micro-tears when they regenerate through time increases the number of muscle fibers and the size of the fibers themselves.

Comparison mitosis meiosis purpose ? ? number of parent cells ? ?

Answers

Explanation:

mitosis has 1 stage and meiosis had 2 stages.

Mitosis produces diploid cells (46 chromosomes) and produces 2 identical daughter cells
Meiosis produces happiness cells (23 chromosomes) and produces 4 genetically different daughter cells

Answer:

Mitosis and meiosis are nuclear division processes that occur during cell division.

Mitosis involves the division of body cells, while meiosis involves the division of sex cells.

The division of a cell occurs once in mitosis but twice in meiosis.

Two daughter cells are produced after mitosis and cytoplasmic division, while four daughter cells are produced after meiosis.

Daughter cells resulting from mitosis are diploid (46 chromosomes), while those resulting from meiosis are haploid (23 chromosomes).

Daughter cells that are the product of mitosis are genetically identical. Daughter cells produced after meiosis are genetically diverse (genes swap during division).

Mitosis has 1 parent and meiosis produces 2 types of sex cells which fuse at fertilisation.
