Sati [7]

Answer:

An autosomal trisomic condition is the deviation of the chromosome number where an extra copy of the chromosome present with the chromosome pair. The three trisomic conditions are Patau - extra copy at chromosome 13, Edward - extra copy of chromosome 18, and Down Syndrome - an extra copy of chromosome 21

Children or fetuses affected by these trisomies show the least life expectancy and develop as mentally week, other than these trisomies other trisomic conditions are highly lethal so we do not see the survivors and it is due to dosage sensitivity which means that increasing or decreasing their expression levels will reduce cell viability.

Offspring grow up to exhibit many of the same characteristics as their parents because of the _______ they receive from their pa
faust18 [17]

Answer:

Genes

Explanation:

A gene is a hereditary unit that parents pass to their offspring, and they will determine the kind of characteristics the baby will have like will they be short or tall, have blue or brown eyes, will they have blond or black hair.  The offspring will get different genes from its parents and it will therefore be genetically unique.  Some traits or characteristics may be dominant over others. For example the mother has brown eyes and the father has blue eyes, so in this case eye color has two alleles (an allele is a specific version of a gene, in this case allele for blue eye color and an allele for brown eye color), and now the baby is born with brown eyes, so brown eye color was dominant over the blue eye color so that is the trait that we will see in the baby.  The genetic is a lot more complex but this is a more simplified explanation of how offspring express certain traits from their parents.

Which strategies are recommended to conserve and manage water? Check all that apply.
stepan [7]

Note that it is asking for conservation and management of water:

Use technology to produce clean water. If technology can be used to create more clean water without losing natural resources, by all means use technology for it.

Use water wisely at home and in industry. This is the definition of conserving water and managing usage of water.

Use techniques and tools to reduce water loss. This is the pathway to conserving water.

Those that are in a grey area:

Take care of living things that live in water. This should occur, and it is managing the water condition, but as for conserving water, that is a different story.

Encourage recreational activities year-round. Recreational activities usually do not have to do with water in a major way, but year-round is a bit too much. Of course, if all these recreational activities use large amounts of water, then it will end up in the "not" section.

Those that are not:

Stop using water in all areas of life. You will need to drink water first off, and a human cannot survive for longer than 3 days without water. You also need water to help you stay clean, as well as other tasks.

Your definite correct answers are the first 3 listed, and the 2 after is up to how you view if it is both managing as well as conserving water.
