Which theory of aging suggests that mechanical functions of the body work less efficiently as people age?

Biology

enyata [817]3 years ago
5 0

It is the wear and tear theory of ageing.

The wear and tear theory defends that ageing is caused by the damage that happens as time goes by to cells and body systems. The name of the theory reflects this idea of wearing out - the organism is worn out and doesn't function normally. This is the theory that's accepted more generally as common sense but there are other theories of ageing that see the process as a more intentional process.

Find the unit rate with the second given unit in the denominator.
Kobotan [32]
First, the unit is words per minute, not the other way round because you're interested in how fast people can type, not how much time passes for every number of words they write or read (that would be minutes per word)

now, we know they do 4200 in 60 minutes. 

we need to divide 4200 by 60- first,\frac{4200}{60} = \frac{420}{6} = \frac{21}{3} =70

so the answer is, 70 words per minute

I think you made a typo in your answer and you meant 4600 instead of 4200 - then the answer is <span>C. 76 2/3 word/min</span>

What is the sequence of cases on dna strand b from left to right? (See picture)
Bas_tet [7]

Answer:Dna template- 5' ACTCCTGAA 3'

3' TGAGGACTT 5' complementary base

Explanation: Dna consist of a double stranded helix structure. Replication occurs to make extra copies of DNA strand. The DNA strand use to make extra copy is the template strand while the mirror image is the complementary base.

Replication occurs in 5' to 3' direction.

For complementary base in DNA Adenine complement thyamine

Cytosine complement Guanine

i.e A-T

C-G

Hence the complementary base in 3'-5' direction is 3' TGAGGACTT 5'
