Schleiden and Schwann suggested the cell theory. It is stated that a single cell makes up every living thing. It implies that the structural and basic unit of life is the cell.
Understanding how cells form, grow, and die enables us to comprehend how all living things function.
Our comprehension of a variety of subjects, including as how new life is created, why organisms take on particular forms, how cancer spreads, how diseases can be treated, and more, is assisted by this collection.
Cells make up all known living things. The structural and operational unit of all living things is the cell. The chemical makeup of each cell is same. Cells are where all of life's energy flow (metabolism, biochemistry) takes place.
Therefore, adult human form singled cell zygotes.

Answer:
The adult human forms from the single-celled zygote.
Explanation:
The cell theory was put by Schleiden and Schwann. It is said that all the living organisms made up of from a single cell. It means the cell is the structural and fundamental unit of life. In human beings, it is also seen. The human comes from the fertilization of haploid sperm and ovum. The zygote is the single fertilized cell that undergoes cell division to form multicellular organisms. The single-cell zygote becomes a multicellular gastrula and forms the 3 germ layers. These three germ layers later form different tissues and organs by organogenesis. This happens due to the mitotic cell division. Thus an adult human will form and the cell division continues till the death of the individual. This process indicates how a single-celled zygote forms the multicellular human.
The control is left alone by the experimenters.
The control group is matched with the experimental group except for the one experimental variable
The control group is exposed to only one variable rather than several.
The first option is correct. The control group is kept in an unchanging environment.
In a research experiment, the control group is another research group that is made up of individuals that resembles the experimental group but are used to make comparisons with the experiment group.
The participants in the control group are not treated like those in the experiment group. Their environment and condition is unchanged. They do not receive the treatments that are given to the experiment group.

b) since Humans showed up 300,000 ya?
Answer:
Explanation:
mammal(X) :- legs(X,4), arms(X,0).
mammal(X) :- legs(X,2), arms(X,2).
mammal(horse).
arms(horse,0).
As far as I can tell, prolog cannot derive that a horse has four legs. Why so? You may ask. I'd say then, because there isn't any rule(s) for prolog to use in determining the legs. Inference rules can also not be used to determine that the fact that a horse is a mammal and it has 0 arms, it certainly must have 4 legs.
Answer:
The answer is "Mode of replication".
Explanation:
The answer is the model for reproduction because it is the genetic reproduction implements a diffraction model, which replaces some old bases with other small colonies for each strand of the fetus, opposed to a semiconservative model of reproduction in eukaryotic cells, wherein one chromosome is completely new and one is old.
Replication in both eukaryotic life and an alien sample would involve the duplication of genetic information, but the specifics could vary. For instance, while eukaryotes use DNA and replication is bi-directional, the alien sample might use RNA and replication could be uni-directional. These are, however, speculative based on our understanding of life on Earth.
In both the eukaryotic life found on Earth and in the hypothetical alien sample, processes of replication would involve the duplication of DNA, which serves as the basis for passing genetic information from one generation to the next. In eukaryotes, this process is accomplished via DNA replication, a bi-directional process in which the DNA helix is unwound and each strand is used as a template for the synthesis of a new complementary strand.
In contrast, we can speculate that the alien sample might have biochemical differences that influence its DNA replication process. The alien sample, for instance, could utilize RNA instead of DNA as the main carrier of genetic information. Its replication process might also proceed in a uni-directional manner, which is contrary to the bi-directional process in eukaryotes. Nevertheless, these differences are more conjectural since we don't have a specific example of extraterrestrial life to examine.

The organism that live in water get oxygen from the oxygen that is dissolved in water.
Oxygen is a gas, that is present 18% in the environment. The oxygen is an important for living beings because all are activities of our body is run by oxygen.
The water also contain oxygen in the dissolved form, which is used by the water organism.
Thus, the oxygen that is dissolved in water.

Most organisms that live in water get oxygen from the dissolved water in the oxygen.

Enzymes are affected by temperature and pH in their ability to catalyze chemical reactions. Extreme temperatures and pH values can denature enzymes, causing them to lose structure and function. The active site of an enzyme is sensitive to changes in the local environment, affecting its ability to bind substrates.
Enzymes are subject to influences by the local environment, including temperature and pH. Increasing or decreasing the temperature outside of an optimal range can affect the chemical bonds within the enzyme's active site, making them less suitable for binding substrates.
Extreme temperatures can cause enzymes to denature, losing their structure and function. Similarly, extreme pH values can also denature enzymes and affect their ability to bind substrates.
