The correct answer is A. Pollution

Explanation:

In ecology, an abiotic factor refers to a factor that is non-living but still affects the living organisms of an ecosystem; additionally, an abiotic limiting factor refers to an abiotic factor that limits or stops the growth of organisms in an ecosystem. This implies, in the case of a pond ecosystem the one that is an abiotic limiting factor of fish is pollution, because this factor is the only one that can be completely classified as non-living because food, disease, and predators are living factors or biotic factors. Besides this, pollution can limitate or stop the population of fish to grow or thrive which also makes pollution a limiting factor.

Pollution :) Since Abiotic means non living.

Bacteria: Living

Food (worms or smaller fish): Living

Predators: Living

Pollution (dirt, trash, or other stuff): Non Living

What is G-banding? What regions of the chromosome (e.g.base composition, condensed or open, early or late replicating) are stain
Wewaii [24]

Answer:

G-banding or Giemsa banding is a technique used to study the chromosomes by staining then at condensed stage. The visible karyotype can be used by this technique. The genetic diseases can be easily identified by this G banding technique.

The base composition of the genes (nucleotide) are stained by the dye known as Giemsa stain. The nitrogenous base adenine and thymine of the heterochromatic region of chromosome stained darkly in this technique. The darkly stained area is generally gene poor area.

The researchers introduced a small RNA complementary to a portion of the mRNA encoding protein A into the Brec-MUT cells growing
Sonbull [250]

Answer:

Delivered small RNAs can inhibit protein A production through the RNA interference (RNAi) mechanism, and thus impairs angiogenesis  

Explanation:

The pregnancy-associated plasma protein-A is a protease enzyme involved in the formation of new blood vessels by increasing insulin-like growth factor I (IGF-I) bioavailability. Moreover, small RNAs (<200 nucleotides in length, generally 18 to 30 nucleotides) are non-coding RNA molecules that function in RNA silencing through the RNA interference (RNAi) pathway. Small RNAs are widely used in molecular biology laboratories because they can be delivered into specific cells in order to silence target mRNAs such as, in this case, the mRNA encoding protein A, by complementary base pairing and thereby inducing translational repression. In consequence, mRNAs complementary to delivered small RNAs are silenced through RNAi pathways, i.e., by cleavage of the target mRNA and/or mRNA destabilization.

What is the name of the structure that composers most of the cell membrane?
noname [10]

The cell membrane consists of three classes of amphipathic lipids: phospholipids, glycolipids, and sterols. The amount of each depends upon the type of cell, but in the majority of cases phospholipids are the most abundant, often contributing for over 50% of all lipids in plasma membranes.
