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.
The short RNA corresponding to a fragment of both the mRNA encoding protein A and B was inserted into Brec-MUT cells that grow in a petri dish by the researchers.
The researchers claim that cells treated with this drug will fail to stimulate blood vessel formation by trying to induce a small RNA complementary to the mRNA of A. It may be so because induced small RNA could act as an antagonist to the mRNA of the A protein. This results in the induction of default or faulty proteins that will not promote vascular permeability.Learn more about Proteins and carbohydrates:

Explanation:
There is higher abundance of lighter elements in the universe than heavier elements.
which sourfe of evidence supports that statement
Cosmic Microwave Background Expanding Universe Universe Composition
Answer:
Due to its formation in the supernova nucleosynthesis.
Explanation:
The higher abundance of lighter elements in the universe than heavier elements occurs due to its formation in the supernova nucleosynthesis. The lighter elements such as hydrogen and helium are present in abundant amount and formed in supernova nucleosynthesis as compared to other heavier elements which are formed through other events. The lighter elements occupy less volume and space as compared to heavier elements which is also a reason for their abundance.

What happens to solar energy at the equator??
Answer:
Pls Brsinliest
Explanation:
The sun's rays strike Earth's surface most directly at the equator. ... Because the sun's rays hit at a slant, the area is heated less. The more focused the rays are, the more energy an area receives and the warmer it is; the less focused the rays are, the less energy an area receives and the cooler it is.

Which energy conversion occurs in the cells of an animal, such as the
chipmunk shown in the photograph?
A. Kinetic energy
Nuclear energy
B. Light energy Chemical energy
O C. Kinetic energy → Potential energy
O D. Chemical energy → Potential energy
The energy conversion that occurs in the cell of an animal, such as the chipmunk, is Chemical energy → Potential energy.
What is the conversion of energy?Energy is neither created nor destroyed, it is just converted into another form of energy. This is called conversion of energy.
Here the food has chemical energy and which will be converted into potential energy in the stomach of the chipmunk.
Thus, the correct option is D. Chemical energy → Potential energy

what is the step in the cell cycle that insures genetic continuity
Answer:
As mitosis ends, each developing daughter cell receives one set of chromosomes. The nuclear membranes return as the cell divides through the process of cytokinesis. In this way, mitosis ensures genetic continuity across generations of cells.

whould you be able to observe the DNA of a single cell?
Answer:
All living things have DNA: the chemical instructions on how to make a living thing, from humans to strawberries. Many people assume that because DNA is so small, we can't see it without powerful microscopes. But in fact, DNA can be easily seen with the naked eye when collected from thousands of cells.

Iceland is a natural laboratory for observing sea-floor spreading. Here, the rate of plate motion is about 2.5 cm per year. Predict how Iceland will change in one million years as a result of plate tectonics. Explain your reasoning.
Answer:
25000 meters.
Explanation:
Iceland will change into parts in one million years as a result of plate tectonics. If the rate of plate motion is about 2.5 cm per year so after one million years the Iceland divides and moves away from one another at a distance of 25000 meters so we can say that both Islands are present at different locations and at a large distance from one another.
AS per the observation, change in one million years as a result of plate tectonics in the islands the correct answer is 25000 meters.
Iceland will extrude into components in 1,000,000 years because of plate tectonics. If the charge of plate movement is ready 2. 5cm in line with 12 months so after 1,000,000 years Iceland divides and movements far from each other at a distance of 25000 meters so we are able to say that each island is a gift at distinctive places and at a big distance from each other.
What is Iceland?Iceland is well-known for being known as the Land of Fire and Ice due to its volcanoes and glaciers. It is dotted with herbal wonders including The Blue Lagoon and Dettifoss Waterfall. Iceland is likewise regarded for its wealthy cultural history, Norse mythology, folklore, and having no reputable own circle of relatives' names.
Thus it is clear that Iceland will change in one million years as a result of plate tectonics by 25000 m.
