How do muscles help the body move?

Biology

Answer:

Muscles pull on joints, which allows us to move. They also assist the body in performing tasks such as chewing and transporting food through the digestive system. Even when we sit absolutely motionless, our muscles are continually moving throughout our bodies.

Answer:

Muscles are attached to bones by tendons and help them to move. When a muscle contracts (bunches up), it gets shorter and so pulls on the bone it is attached to. When a muscle relaxes, it goes back to its normal size. So it helps the body to move by letting us be firm and have the ability to balance and do many things we couldn't without bones.

Which is an example of a substitution mutation?
Marta_Voda [28]

Answer:

CAT - GGC - TAC mutates to CAT - GGC - TAG

Explanation:

Changes occur in the nucleotide sequence of the DNA molecule. These changes referred to as MUTATION are usually due mistakes during DNA replication or induced by mutagens (mutation-causing substances). Mutation can be of different types depending on the kind of change that occured to the nucleotide sequence. Based on this question, one of the mutation types is SUBSTITUTION MUTATION.

Substitution mutation is a kind of mutation in which one or more nucleotide base replaces another in the sequence.

The option that suits an example of substitution mutation is: CAT - GGC - TAC mutates to CAT - GGC - TAG because Guanine nucleotide replaces Cytosine nucleotide in the third CODON i.e. TAC becomes TAG.

HELPP PLSSS :) American pikas are prey to long-tailed weasels. Which change in a limiting factor would increase the carrying cap
Damm [24]

Answer:

A. increase in American pika population size

Explanation:

Carrying capacity is the idea that relates to how much population can an environment sustain before collapsing. Here, the answer would be A. increase in American pika population size  because if you increase the food for weasals, naturally the population carrying capacity goes up because now the environment has food to feed the weasals which can contribute to increasing the carrying capacity (i.e. the environment can now handle larger population of weasel than initial condition)
