Proteins are polymers.
a. True
b. False

Answers

False

Proteins are polymers of molecules called amino acids, some contain thousands. Lipids are formed when a glycerol molecule combines with compounds called fatty acids, therefore they are not polymers because they contain one molecule and are not macromolecules. Hope this helps! :)

PLEASE HELP ME FAASSSTTTT Compare and contrast genetic engineering to the process of natural selection. Select all statements that are true.


1) By selecting the genetic information that is passed on to future generations, genetic engineering is similar to natural selection.

2) Unlike natural selection, genetic engineering selects the organisms most beneficial to the environment.

3) By selecting the genetic information that is passed on to future generations, genetic engineering can happen at a different rate than natural selection.

4) Like natural selection, genetic engineering may be used on all organisms, including humans.

5) The effects of genetic engineering apply only to the organism selected, but natural selection affects the entire population.

Answers

Answer:

1) By selecting the genetic information that is passed on to future generations, genetic engineering is similar to natural selection.

3) By selecting the genetic information that is passed on to future generations, genetic engineering can happen at a different rate than natural selection.

4) Like natural selection, genetic engineering may be used on all organisms, including humans.

Explanation: In natural selection there is overtime selection for one particular trait and is mostly based on phenotype, whilst genetic engineering uses genotype of an organism  and it is the deliberate modification of an organism by manipulating  the genetic material

What observation led researchers to propose that chloroplasts evolved from cyanobacteria? A) Both produce proteins. B) Both contain mitochondria. C) Both provide structure to cells. D) Both perform photosynthesis.

Answers

(D) Both perform photosynthesis is the observation that led researchers to propose that chloroplasts evolved from cyanobacteria.
Chloroplasts is the area where photosynthesis takes place. It is a green organelle in a plant cell. Pigments called the chloros in a chlorophyll are needed for the photosynthesis.
Cyanobacteria or blue-gree algae contains a blue photosynthetic pigment and a chlorophyll for photosynthesis.
