Question

which of the following statements accurately describes similarities between asexual and sexual reproduction in animals?

both asexual reproduction and sexual reproduction rely on parental chromosomes to mix in new ways.

both processes generate offspring that carry parental genes.

both processes increase genetic variation in offspring.

both forms of reproduction produce offspring that have double the amount of genetic information of the parent(s).

insulin is a protein hormone that helps cells use glucose. in type 1 diabetes, insulin - making cells in the pancreas are attacked and destroyed. this is an example of

the importance of the excretory system in removing wastes and other toxins from the body.

the importance of only one system being needed to perform a function.

the digestive, circulatory, and excretory systems affecting one another.

the endocrine, digestive, circulatory, and immune systems affecting one another.

Explanation:

First Question (Reproduction in Animals)

• For the first option: Asexual reproduction (e.g., binary fission, budding) does not involve mixing of parental chromosomes (only one parent, so no mixing), while sexual reproduction does. So this is incorrect.
• Second option: In asexual reproduction, offspring are clones (carry parent's genes), and in sexual reproduction, offspring carry a combination of both parents' genes. So both do carry parental genes. This is correct.
• Third option: Asexual reproduction produces genetically identical offspring (no genetic variation increase), while sexual reproduction does. So this is incorrect.
• Fourth option: Asexual reproduction offspring have same genetic info as parent (not double), sexual reproduction offspring have half from each parent (total same as parent, not double). So incorrect.

• Insulin is a hormone (endocrine system). Glucose is from digestion (digestive system), transported by circulatory system. In type 1 diabetes, immune system attacks insulin - making cells. So endocrine (insulin), digestive (glucose source), circulatory (transports glucose/insulin), and immune (attacks cells) systems are involved and affect each other.
• First option: Excretory system not main focus here (about insulin and immune attack), incorrect.
• Second option: Multiple systems involved, not just one, incorrect.
• Third option: Endocrine and immune systems also involved, not just digestive, circulatory, excretory, incorrect.

Answer:

Both processes generate offspring that carry parental genes.
