Chemicals like Titanium dioxide and photovoltaic cells are artificial chemicals that behave like chlorophyll.
What do you mean by Artificial chemicals?Artificial chemicals may be defined as chemicals that are synthesized by the activity of humans and their processes.
The nanoparticles of titanium dioxide have the ability to increase the light-capturing potential of a surface, while a photovoltaic cell enables sunlight to be processed into usable electricity by exciting outer shell electrons on some metals. These substances also behave naturally and initiate the reactions in the reaction center present in the chloroplast.
Therefore, Chemicals like Titanium dioxide and photovoltaic cells are artificial chemicals that behave like chlorophyll functionally.

Sacchromyces is a type of yeast preferred by bakers because it grows very quickly. It makes large
numbers of clones in a very short amount of time. What property of yeast makes it grow in number so
rapidly?
meiotic division by sexual reproduction
binary fission by sexual reproduction
parthenogenetic asexual reproduction
budding through asexual reproduction
Answer:
d
Explanation:
The property of yeast makes it grow in number so rapidly because budding through asexual reproduction. Thus, option D is correct.
What is asexual reproduction?The mode of reproduction which involves only single parent is known as asexual mode of reproduction. The example of the asexual reproduction are several and these are budding, fragmentation, spore formation, and binary fission.
Reproduction will be defined as the process which has been carried out by the living organisms and during this process of reproduction the living organisms has been produced their own young ones as well as feed them. Reproduction has been known as the supreme quality of living things.There are mainly two types of the reproduction and these are sexual as well as asexual reproduction.
The process of the reproduction in which two parents are involved has been said to be sexual mode of the reproduction and the process of reproduction in which only single parent has been involved is known as asexual mode of reproduction. The example of asexual reproduction are budding, fragmentation, spore formation, and binary fission.
Therefore, the property of yeast makes it grow in number so rapidly because budding through asexual reproduction. Thus, option D is correct.

individuals do not evolve.Populations evolve. True or False?
Answer: false
Explanation:
Individuals do not evolve as a result of natural selection over successive generations. Populations evolve ONLY as certain traits become more common and others go away.
Answer:
False
Explanation:
Singular living beings don't evolve, they hold similar qualities for an amazing duration. At the point when a populace is advancing, the proportion of various hereditary sorts is evolving. Hope this helps!

The diagram below shows hydrogen bonds between water molecules.
What describes each hydrogen bond?
1. An attraction between neutral ends of two molecules.
2. An attraction between the positive end of one molecule and the negative end of another molecule.
3. An attraction between positive ends of two molecules.
4. An attraction between negative ends of two molecules.
hydrogen bonds between water molecules. An attraction between the positive end of one molecule and the negative end of another molecule describes each hydrogen bond.
What are the characteristics of water ?Water is amphoteric in nature because it serve as both acid and a base, highly viscous in nature due to the presence of a force of attraction between molecules.
Water is participate in Redox reaction as it help in release of dihydrogen molecules easily, the dielectric constant is also high, form the connections with other chemical compounds known as hydrates.
The temperature below 4 degrees Celsius the water ordinarily behaves, when it is cooled further, its unusual properties of water molecule are being observed.
During cooled condition, the density of water can also slowly increases and further cooled down leads to decrease in the density of water and the expansion of matter called as the anomalous property of water.

What is Tissue Culture?
Tissue culture is the process of growth of tissues or cells in an artificial medium that is separate from the parent organism. This technique is also known as micropropagation method. It is typically facilitated via the use of a liquid, a semi-solid, or a solid growth medium, such as the broth or agar medium.
Tissue culture is used widely in science for the propagation of plants, in the study of medicines such as those related to cancer. Tissue culture can be used as a treatment option in cancer as this technique does not show any harmful or ineffective medication. The cultured tissues of stem cells can be used for replacement of infected cells or body parts.

A researcher observes the enzymatic polymerization of an organic molecule in a cell. Which enzyme is
MOST likely responsible for catalyzing the reaction?
A. a protein
O B. a nucleic acid
O C. a lipid
D. a carbohydrate
Answer:
A. a protein
Explanation:
Proteins function as enzymes in most of the catalyzing reactions, that increases the rate of reaction within cell.
Proteins are consist of multiple numbers of amino acids and the twisting and folding amino acids provide a unique identity to enzymes. Not all the proteins are enzymes but all the enzymes are proteins.
For example: Trypsin, Pepsin, and Lipases.
Hence, the correct option is "A. a protein".
