Answer:

As early as the 9th century, it was suggested when organisms change, they may be better adapting to survive.

Explanation:

Natural selection, also called Survival of the Fittest, is the process in which the environment influences the fitness of species: <u>organisms that change to adapt better to the conditions they live in, have longer lives and reproduce to leave offspring with the same positive traits</u>.

Two very important people in the development of Evolution Theory are Lamarck (he came up with the theory of acquired characteristics) and Darwin (applied the 'survival of the fittest' to every organism on Earth).

RNAi-based modification of amylopectin content in wheat occurs through decreased expression of starch-branching enzymes. If the

kicyunya [14]

If siRNA against a starch-branching enzyme was transmitted to humans, then it may affect the expression of glycogen-branching enzymes. RNAi inhibits gene expression.

Glycogen-branching enzymes are similar to starch-branching enzymes because glycogen bonds are similar to those observed between amylopectin.

The RNA interference (RNAi) pathway is an evolutionarily conserved mechanism used in molecular biology laboratories to inhibit the expression of target genes.

In the RNAi technique, a regulatory non-coding RNA called small interfering RNA (siRNA) that exhibits sequence complementary to the target gene sequence is used to inhibit and/or block the translation of the target mRNA (in this case, starch/glycogen-branching mRNA coding enzyme).

What type of cells are unspecialized but can become specialized?

oksian1 [2.3K]

An unspecialized cell that can divide and give rise to different specialized cells is called a stem cell (Figure above). Zygotes and embryonic cells are both types of stem cells. These stem cells, called embryonic stem cells, can divide indefinitely and can specialize into any cell type. They are totipotent.

A plant homozygous for the unlinked dominant alleles A, B and G is crossed with another plant that is homozygous for the recessi

fomenos

Answer:

9/64

Explanation:

Given, AABBGG X aabbgg = AaBbGg (F1)

Resulting F1 progeny is self fertilized.

AaBbGg X AaBbGg :

If we check individual crosses:

A a

A AA Aa

a Aa aa

3/4 of the progeny will display dominant A phenotype ( AA, Aa ). Similarly,

3/4 of the progeny will display dominant B phenotype ( BB, Bb ).

G g

G GG Gg

g Gg gg

1/4 of the progeny will display recessive g phenotype (gg).

Total offspring that will display ABg phenotype =

3/4 * 3/4 * 1/4 = 9/64
