Answer:
focus
The Sun is at one focus. The planet follows the ellipse in its orbit, meaning that the planet to Sun distance is constantly changing as the planet goes around its orbit. Kepler's Second Law: the imaginary line joining a planet and the Sun sweeps equal areas of space during equal time intervals as the planet orbits.

the enzyme dicer chops dsrna molecules into small pieces of
The enzyme dicer chops dsRNA molecules into small pieces of miRNA and siRNA. The correct option is B.
What is Dicer?
Dicer is an enzyme involved in RNA interference (RNAi), a cellular process that regulates gene expression.
Its primary role is to cleave double-stranded RNA (dsRNA) molecules into smaller fragments.
These fragments are typically around 21-25 nucleotides in length and serve as the building blocks for two types of small RNA molecules: microRNA (miRNA) and small interfering RNA (siRNA).
miRNAs are endogenous small RNA molecules that play a crucial role in post-transcriptional gene regulation. siRNAs are also small RNA molecules but are primarily involved in the defense against viral infections and the silencing of transposable elements.Thus, the correct option is B.

what are the cell theories formulated by schwann and schielden?
Answer:
By the late 1830s, botanist Matthias Schleiden and zoologist Theodor Schwann were studying tissues and proposed the unified cell theory. The unified cell theory states that: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells.

!!!!NEED HELP ASAP ILL GIVE BRAINLIEST AND 25 POINTS!!!!! How do proteins help transport of materials through the membrane?
Answer:
Channel proteins can aid in the facilitated diffusion of substances by forming a hydrophilic passage through the plasma membrane through which polar and charged substances can pass.
Explanation:
Answer: By forming a continuous protein pathway across the membrane, these proteins enable specific hydrophilic solutes to cross the membrane without coming into direct contact with the hydrophobic interior of the lipid bilayer. Carrier proteins and channel proteins are the two major classes of membrane transport proteins.

within a forest ecosystem, there is a large amount of diversity among members of a warbler species. of the following stages of meiosis illustrated for a typical cell, which contributes most to diversity among the warblers?
Crossing over occurs between homologous chromosomes, and is closely involved in genetic variation. The stage that most contributes to diversity is stage C, where you can see chromosomes after crossing-over.
----------------------------
There are different mechanisms involved in producing genetic variation among descendants. These are,
Crossing-over between homologous chromosomes (prophase 1), Random lining of homologous chromosomes (metaphase 1),Random fertilizationThe Crossing-over events occur between two homologous chromosomes in the equatorial plane and make the daughter cells genetically different from the original one.
The Chiasma is the position where two homologous chromatids interchange genetic information, giving a place for new genetic material or information to be provided to descendants.
After crossing over, homologous chromosomes get separated again.
In the attached imaged there are four different stages of meiosis.
Stage C is the one that contributes the most to diversity.
We can see that crossing over has already occurred between homologous chromosomes, and they have already interchanged segments.
In the image you will see the difference between chromosomes that has gone through the crossing over mechanism, and chromosomes that has not. The difference in color represents segments interchange and variation.
