The phenomenon that occurs when the Sun crosses the plane of Earth's equator is equinox. An equinox is commonly regarded as the moment the plane of Earth's equator passes through the center of the Sun's disk, which occurs twice each year, around 20 March and 22-23 September.
In prokaryotes, new mutations accumulate quickly in populations, while in eukaryotes, new mutations accumulate much more slowly. The primary reasons for this are prokaryotes reproduce quickly and have vast populations.
<h2> Prokaryotes V/S Eukaryotes</h2><h3>Prokaryotes</h3>
Prokaryotes are organisms consisting of cells that don't have cell nuclei or any organelles that are enclosed in membranes. It follows that prokaryote's DNA is not contained within a nucleus.
The following components could be found in a normal prokaryotic cell:
- The membrane enclosing and guarding the cell is known as the cell wall.
- All of the cell's internal components, excluding the nucleus, are called cytoplasm.
- Some prokaryotic cells have filaments made of proteins called flagella and pili.
- A nucleoid is a cell structure that resembles a nucleus and contains genetic material.
- A plasmid is a little DNA molecule with independent reproduction.
<h3>Eukaryotes</h3>
Eukaryotes are organisms made up of cells with membrane-bound organelles and a nucleus that contains DNA in the form of chromosomes. Eukaryotic organisms can have several cells or just one cell. Eukaryotes make up all animal life. Protists, fungi, and plants are examples of additional eukaryotes.

Answer and Explanation:
a. This is a complete flower. Complete flowers are those formed by chalice, corolla, androecium and gynoecium. In the case of the flower presented above, we can see that it has gynoecium because it has a stigma that is part of the gynoecium composition. We can also see that she has androecium, because she has an anther that is part of the composition of androecium. The flower also has a corolla and chalice, since the chalice is formed by the sepals and the corolla by the petals.
b. This is a perfect flower, as we can see that androecium and gynoecium are present in the same flower. Imperfect flowers are those with only androecium or gynoecium.
c. The flower has bilateral symmetry, which is common in all orchids. This type of symmetry allows the flower to only be divided into two equal parts. Radial symmetry, on the other hand, allows flowers to be divided into many equal parts.

Answer: An autotroph is an organism that can generate it's own nutrients. In the example, you see a relationship which allows the pea aphid to gain more energy, but not produce it.
And heterotroph is an organisms that can't generate it's own nutrients, and therefore needs to feed on something, which is the case of pea aphids.
C is the answer
