Answer:
by mimicking disease agents and stimulating the immune system to build up defenses against them.
Explanation:
The Polio virus usually enters the environment in the feces of someone who is infected
Polio spreads from muscle to the central nervous system by neutral pathways
Answer:
So, it produces gametes I wouldn't say gametes cause meiosis so false, hope this helps.
Explanation:
It produces gametes with unique chromosomal combinations. Two gametes combine to form an offspring in se-xual reproduction. Meiosis I occurs within female cells and leads to the formation of egg cells (oocytes). Meiosis II occurs within male cells and leads to the formation of sp-erm cells.
Answer:

Biotic factors that affect earthworm include predator, food, e.t.c
Explanation:
Biotic factors are factors that are inclined with living organism
Answer:
The correct answer is A. Sexual reproduction produces a greater variation in offspring.
Explanation:
- B is wrong because in sexual reproduction there are two organisms involved who combine their DNA, therefore resulting in non-identical offsprings.
- C is wrong because sexual reproduction requires the two organisms involved to exchange DNA's whereas asexual reproduction involves only one organism which only copies it's own DNA for reproduction.
- D is wrong because there are no risks as genetic defects and no need to seek a mate or it is easier than sexual reproduction which results in lower risks for the parents in asexual reproduction.
- E is wrong because asexual production is a more efficient procedure and results in a faster growing population because there is no need to search a mate.
- The answer is A because in sexual reproduction, two different DNA's from both parents get combined resulting in more variation in offspring. In asexual reproduction, there is only one set of DNA which does not allow the gene's to mix, causing a less diverse offspring.
