How can you distinguish a clastic rock from that of a bioclastic rock
IRISSAK [1]

<u>Bioclastic</u> rocks are actually sub-parts of <u>clastic</u> rocks, not a completely different thing altogether.

<u>Clastic</u> rocks are made up of loosened bits of pre-existing rocks. These rocks are formed from weathering, breaking those larger rocks down into little particles (for example, a grain of sand) due to external weather factors such as wind or rain. Some examples of these rocks would be sandstone, conglomerate, and silistone. They are classified by the size and shape of the fragments they are made up of.

<u>Bioclastic</u> rocks are also made up of loosened bits, however, they are not made of rock. They are made of fossils and biogenic (made by living organisms) particles (for example, pieces of shells and coral). These rocks are formed from small parts of pre-existing organisms compacting together to form a rock. Examples of this type of rock would be coquina and limestone, or more specifically, bioclastic limestone. Bioclastic rocks have a very crystalline texture and it is highly likely that you will see a shell in this rock type.

A dihybrid cross is performed between plants that differ in two Mendelian traits: Stem length (T or t) and flower coloration (R
Dahasolnce [82]

Answer:

A. 3/16

Explanation:

The four possible outcomes for Stem length are:

Tt, tT, TT and tt.

The dominant trait (tall stems) will manifest itself in 3 out of 4 outcomes, so its ratio is 3/4.

The four possible outcomes for flower coloration are:

Rr, rR, RR and rr.

The non-dominant trait (white flowers) will manifest itself in 1 out of 4 outcomes, so its ratio is 1/4.

Multiplying both ratios gives us the ratio of offspring that have tall stems and white flowers:

\frac{3}{4}*\frac{1}{4}=\frac{3}{16}

Therefore, the answer is A. 3/16

Which of the following statements characterizes an excitatory neuron?. -It sends an impulse back to the cell body of a neuron.

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).
