what is photosynthesis ?The process in which sunlight energy is used by plants, algae and certain bacteria convert them into chemical energy and starch called as photosynthesis.
Photosynthesis occur in chloroplast which has its own DNA, genes and hence can synthesize their own proteins, photosynthetic Pigments responsible for trapping sunlight present in chlorophyll pigment of chloroplast, like chlorophyll a, b and c.
Bacteria also have chlorophyll known as bacteriochlorophyll can absorb infrared rays, other pigments are Carotenoids which are yellow, orange or red-coloured pigments that absorb bluish-green light., Xanthophyll, Phycobilins.
plastids are found in the cytoplasm of eukaryotic photosynthetic organisms. They contain pigments and store nutrients. Plastids are of three types such as Leucoplast, Chromoplasts, Chloroplasts

how does messenger rna work inside the cell
Answer:
A RNA polymerase separates the hydrogen bases of a gene to produce a strand of messenger RNA, which leaves to nucleus. When a ribosome attaches itself to the messenger RNA, it reads the RNA 3 bases at a time to build amino acids which are then folded into proteins.
More explained process:
Note: The description below will explain the process of “protein synthesis”, in which the mRNA (messenger RNA) takes part of.
In the process of protein synthesis, the first step is called “transcription”. In transcription, the mRNA (messenger RNA) unwinds DNA base pairs, and pairs it with the single strand of RNA (A,U,C,&G) . Then the mRNA moves out of the nucleus and into the cytoplasm to ribosome. That process is called “translation”. In translation, there is a molecule called tRNA (transfer RNA). There is an amino acid which corresponds to the base pairs of RNA in top, which will create a chain of amino acids. [ For example, the bases are AUC, the corresponding amino acid will be isoleucine (Ile). Next, the tRNA molecules carry the amino acids to mRNA, reads the RNA 3 bases at a time to build an amino acid chain which are then folded into proteins.

Answer:
Adenine, Thymine, Guanine, and Cytosine
They possess complimentary paring. Meaning the one will only bind another, and will not bind with and other one
Explanation:
DNA has four types of bases, such as adenine (A), guanine (G), cytosine (C), and thymine (T). Adenine forms double hydrogen bonds with thymine, while guanine forms triple hydrogen bonds with cytosine.
What is the composition of the DNA?
DNA is called deoxyribonucleic acid. It is a polymer of nucleotides. Each nucleotide is made up of a phosphate, a pentose sugar, and a nitrogenous base. In DNA, there are four types of nitrogenous bases, such as adenine (A), guanine (G), cytosine (C), and thymine (T).
Adenine and guanine are purines and double-ringed structures. Cytosine and thymine are pyrimidines and single-ringed structures. A purine forms a bond with a pyrimidine. Adenine (A) forms a double hydrogen bond with Thymine (T), and Guanine (G) forms triple hydrogen bonds with Cytosine(C).
Hence, in DNA, four nucleotides are found: adenine (A), guanine (G), cytosine (C), and thymine (T). Adenine pairs with thymine, while guanine pairs with cytosine.

Gravity and our Solar System The Sun’s gravity is what holds our solar system together. Planets and Gravity Since Jupiter is the largest planet, it has the most gravity. Pluto has the least amount of gravity of all the planets. A theory from Sir Isaac Newton states that Gravity is greater when mass is larger and distance is shorter.
the concentration of carbon dioxide in the atmosphere has been increasing for many years, how might this increase affect photosynthesis
Answer:
the answer is
Carbon dioxide concentrations are rising mostly because of the fossil fuels that people are burning for energy.Increasing the light intensity increases the rate of photosynthesis, until some other factor a limiting factor becomes in short supply. At very high light intensities,photosynthesis is slowed and then inhibited, but these light intensities do not occur in nature.

A. All organisms have the same number of chromosomes
B. All chromosomes have the same number of DNA nucleotide base pairs
C. All DNA contains the same bases that code the same amino acids
D. All SNA is passed from one generation to the next during reproduction
Answer:
D Hope this is right......
All DNA is passed from one generation to the next during reproduction. So the correct option is D.
What is the DNA?DNA or deoxyribonucleic acid is a polynucleotide molecule. Each nucleotide of DNA is composed of one nitrogen base, one deoxyribose sugar and one phosphate group.
The nucleotides are bonded with each other by the formation of phosphodiester bonds which liberate a water molecule.
The nitrogen base in the DNA is of four types. Adenine, Thymine, Cytosine and Guanine. The DNA is present in a double-stranded form and the nitrogen base is attached to each other in both the strands with the help of hydrogen bonds.
The nitrogen bases join with each other by the base pairing rule. Adenine joins to thymine and guanine joins to cytosine.
DNA a genetic material and a hereditary material. It is responsible for the functioning of an organism and the transmission of hereditary traits from one generation to the next.
Therefore the correct option is D.

What would need to happen in order for you to maintain your immune cells throughout your lifetime?
Answer:
Immunity is one of the most concern topic of human health now a days. So, to maintain our immune cells throughout our lifetime, we can follow the following tips:
Eat a healthy diet: It is important to take nutrient-rich diet so that our immune system can fight against the disease causing bacteria or virus and keeps us healthy enough.
Get active: Regular exercise and keeping ourselves active keeps our muscles and body fit and provide energy to our immune cells.
Get plenty of sleep: Sleeping is one of the way to stay healthy but it should be limited. Its important to give rest to your body so for that its important to take 6 to 7 hrs of sleep per day.
Maintain body weight: overweight can weaken our immune cells, so important to maintain our body weight with physical activity and eating a healthy diet that will keep our immune cells throughout our lifetime.
Quit smoking and other harmful habits: Smoking makes our immune cells weak and slowly our body get prone to diseases. So, to keep immune cells healthy one should quit smoking.
The atomic mass of arsenic is 75 atomic mass units; a neutral atom of asennic has 33 electrons. how many neutrons does arsenic normally have?
a.33 b.42 c.75 d.108
Answer:
42
Explanation:
Atoms have a neutral charge overall, which means they have an equal numbers of positively-charged protons and negatively-charged electrons. Here, an atom of arsenic with 33 electrons must also have 33 protons.
The mass of any atom is contained in its nucleus, a part made up of protons and neutrons - particles with no charge. Both protons and neutrons are exactly 1 atomic mass unit each, so to find the atomic mass of an atom, we can use the formula
(# of protons) + (# of neutrons) = atomic mass
or equivalently:
atomic mass - (# of protons) = (# of neutrons).
For arsenic, we have an atomic mass of 75 amu and 33 protons, so using our formula:
# of neutron = 75 - 33 = 42 neutrons

Which model shows how an image appears to a person when they look through a concave lens
Answer:
A
Explanation:
Object appears smaller to the eye
Model A shows how an image appears to a person when they look through a concave lens.
What is a concave lens?A concave lens is a type of optical lens that has a curved inward surface, causing light rays to diverge after passing through it. It is also sometimes called a diverging lens. The opposite of a concave lens is a convex lens, which has a curved outward surface and causes light rays to converge.
In optics, the shape of a lens determines how it affects the path of light rays passing through it. A concave lens spreads out light rays, making them diverge, and the resulting image is usually smaller, inverted, and appears to be located behind the lens. Concave lenses are often used in applications where it is necessary to reduce the size of an image, such as in microscopes, cameras, and other optical devices.
It's important to note that the properties of a concave lens depend on its size and shape, as well as the distance of the object from the lens and the type of light being used. By manipulating these parameters, engineers and scientists can design concave lenses with specific optical properties for different applications.
