Answer:
Photosynthetic reaction center differ from the chlorophyll molecules in the antenna complex by the presence and absence of core pigment and accessory pigment.
Explanation:
Photosynthetic reaction center contain core pigment known as chlorophyll A which can aborb wavelength of sunlight not more than 700 nm in case of Photosystem 1 and the core chlorophyll pigment of Photosystem 2 absorb light having wavelength of 680nm or less than that.
Antenna complex or light harvesting complex such as chlorophyll b ,Carotenoid,Xanthophyll absorb light energy from sunlight and transfer that light energy to photosynthetic reaction center by resonance energy transfer so that the photosynthetic reaction center uses the same(light energy) in form of chemical energy to out the further reactions of photosynthesis.
Answer:option C= mRNA
Explanation:
MACROMOLECULES are large molecules, such as protein, commonly created by the polymerization of smaller sub-units called monomers.
The NUCLEAR PORE is a protein-lined channel in the nuclear envelope. The NUCLEAR PORE regulates the transportation of molecules between the nucleus and the cytoplasm. In eukaryotic cells, the nucleus is separated from the cytoplasm and surrounded by a nuclear envelope.
mRNA is synthesized by DNA during a process known as the TRANSCRIPTION. After the synthesis, the new molecule moves from the nucleus to the cytoplasm. It passes through the nuclear membrane through a NUCLEAR PORE. Then, it will later join with a ribosome, which is just coming together from its two sub-units, one large and one small.

Answer:
A mutation is a change in a DNA sequence. Mutations can result from DNA copying mistakes made during cell division, exposure to ionizing radiation, exposure to chemicals
called mutagens, or infection by viruses. Germ line mutations occur in the eggs and sperm and can be passed on to offspring, while somatic mutations occur in body cells and are not passed on.
Mutation has been the source of many Hollywood movies, but it's really a simple process of a mistake made in a DNA sequence as it's being copied. Some of that's just the background noise that DNA copying is not perfect, and we should be glad of that or evolution couldn't operate. But mutation can also be induced by things like radiation or carcinogens in a way that can increase the risk of cancers or birth defects. But it's pretty simple; it's basically an induced misspelling of the DNA sequence.
That's a mutation.
When a variant alters a protein that plays a critical role in the body, it can disrupt normal development or cause a health condition. A condition caused by variants in one or more genes is called a genetic disorder. In some cases, gene variants are so severe that they prevent an embryo from surviving until birth.
A simple example is a connection between the circulatory and respiratory systems. <span>As </span>blood<span> circulates through your body, it eventually needs fresh oxygen </span><span>from the air. When the </span>blood<span> reaches the lungs, part of the </span>respiratory system<span>, the </span>blood<span> is re-oxygenated.</span>
