Answer:
Alveoli
Explanation:
During gas exchange oxygen moves from the lungs to the bloodstream. At the same time carbon dioxide passes from the blood to the lungs. This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.
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.
Answer:
Ammonia and Carbon Dioxide
Explanation:
It is Ammonia and Carbon dioxide, stage 2 of the atmosphere. Little or no traces of oxygen or Nitrogen.
Hope this helps plz hit teh crown :D
OA. A whale is a mammal that does not live on land.
B. A fish is not a mammal and does not live on land.
OC. A horse is a mammal that lives on land.
D. A snake is not a mammal but lives on land.
Whales are marine mammals that do not live on land, disproving the conjecture that all mammals live on land.
The correct counterexample that shows the conjecture “All mammals live on land” is false is option A. A whale is a mammal that does not live on land. Whales are marine mammals and live in water their entire lives. This counterexample disproves the conjecture that all mammals live on land.
Answer:
Cell serves as the basic building blocks for building the structure or the body of the living organisms. Now, certain type or specific number of cells come closer and arrange themselves in such a sequence that they need to perform a unique or specific task by making up a whole organ structure.
Explanation:
There are certain cells inside the human body which makes up a single organ and then performs the whole function specifically by themselves, as we have the "myocardial myocytes". These are the specific type of cells which are required for the heart's cardiac muscles to develop or grow in a given pattern. As these cells are specialized for making up or building up of the cardiac muscles which in turns results in the heart structure. And performs the basic function of supply of blood and the required materials i.e nutrients to the different cells and organs.
C. Polypeptide formation.
D. Transcription.
E. Translation.
DNA, the RNA polymerase core enzyme, and the subunit are the first transcriptional components. mRNA, small and large ribosomal subunits, initiation and elongation factors, as well as tRNA, are all parts of the translation process. Thus, option D is correct.
Proteins called transcription factors are involved in the process of turning DNA into RNA, or transcribed DNA.
A large variety of proteins—aside from RNA polymerase—called transcription factors start and control how genes are transcribed.
A gene's transcription is boosted by transcription factors that serve as activators. Reducers lessen transcribing.
An enhancer or silencer is a collection of transcription factor binding sites that can turn a gene on or off in a particular region of the body.
Therefore, Transcription is the process in which a strand of DNA is used as a template for the manufacture of a strand of pre-mRNA.
