1. Similarities:
they are both processes of cell division by which cells reproduce.
They share several steps of the process(prophase, metaphase, anaphase e telophase, cytokinesis) but meiosis has another division also with those same steps.
In both cases the cell duplicates its DNA by pulling it
apart into two sets, place the sets on each end of the cell, and then
divide down the middle.
Both produce new cells
based on their parent cells' genes.
2. The differences:
Mitosis:
- has 1 division per cycle
- one cell produces 2 new cells
- the genetic information in the mother-cell and the daughter-cells are the same. ( the number of chromosomes is also the same)
- it occurs in somatic cells
Meiosis:
- two divisions per cycle.
- one cell when divides produces 4 new cells
- the new cells have different genetic information. mixes the the genetic material from the
parent cells
- the number of chromosomes of the daughter cells is half of the mother's.
Eukaryotes always have a cell membrane, but prokaryotes don't. Eukaryotic and Prokaryotic cells are both
building blocks of life in different organisms. The main difference of two is
in its structures. Eukaryotic cells contain organelles that are found
inside membranes, like the nucleus, which stores chromosomes and DNA.
Prokaryotic cells don't have a nucleus and no true chromosomes. Prokaryotic cells
are unicellular while eukaryotes are multicellular. The presence of
mitochondria, chloroplasts, and cell wall are all distinct to Eukaryotic cells.
Eukaryotic cells are found in animals and plants, while bacteria and archaea
have prokaryotic cells.<span>

Im sorry I only know the first one. :( Wish I could help 100%
Engaging in aerobic exercise makes <u>skeletal muscles more resistant to fatigue</u>
Explanation:
Aerobic exercises increase muscle strength and endurance.
Aerobic exercises use the oxygen present in the muscles to generate energy and prevent lactic acid buildup. These exercises help to utilize the fat reserves for energy production.
These exercises are a series of short and long duration which induce sustained periodic muscle contractions.
These activities mainly act on Type 1 or the slow-twitch muscle fibers which can sustain the maximal amount of contractions for even a long period.
The application of slow-twitch muscle fibers and the presence of oxygen together helps to build the resistance to muscle fatigue of skeletal muscles.
Anaerobic exercises are resistance exercises which builds muscle mass.
