Plants need this waxy outer coating, also known as a cuticle, for a
variety of reasons. The cuticle keeps the important things the plant
needs in, such as water and carbon dioxide, and the things the plant
doesn't need, such as too much heat, out. It performs a few different
functions, including protecting the important cells needed for
photosynthesis.
Answer:
C) binding to mRNAs and degrading them or blocking their translation
Explanation:
<u>miRNAs:</u>
miRNAs is the abbreviation of MicroRNAs. These are the small noncoding RNAs of ∼22 nucleotides which can not code for peptides. miRNAs are responsible for gene expression regulation at the level of post transcription. They can do so by forming complementary base pairing with target mRNA and inhibiting their translation.
They silenced mRNA by the following processes:
(1) Cleavage of the mRNA strand into pieces,
(2) stopping mRNA from translation into proteins by ribosomes.
(3) Shortening of mRNA poly(A) tail and destabilizing it.
Answer:
d.
Explanation:
Your body uses two types of molecules for storing energy, the carbohydrates are the main type and its used for short term storage, and for immediate use by the body. And the lipids or fats, are used for long term storage in the body, because they can store more energy in the same volume than a carbohydrate.

Answer:
Let's have our alleles be J = dominant, j = recessive. And for fun let's make the dominant phenotype black coat, the recessive brown coat.
Heterozygous x homozygous recessive
= Jj x jj
Punnett square:
J j
j Jj jj
j Jj jj
Genotypic ratio: 2 Jj : 2 jj, or a one-to-one ratio of Jj to jj.
Phenotypic ratio: 2 black : 2 brown, or a one-to-one ratio of black to brown.
