The given section of DNA is known as a gene.
Explanation:
The basic physical as well as fundamental unit of heredity is known as gene. Genes are built with DNA. According to Human Genome Project human have estimated between 20000 to 25000 genes. In Every person two copies of each gene are present which is carried from parent.
In most of the genes are common almost every people but less than 1% of genes are different between people. The role of gene is to determine the trait- how we look and also other stuff about us.
Answer:
Explain the terms “criteria” and “constraints.” Criteria are things the design needs to do in order to be successful--its requirements. Constraints are limitations on the design. These may be materials available, the cost of the materials, the amount of time they have to develop the solution, etc.
Design criteria are the explicit goals that a project must achieve in order to be successful. ... Design criteria can be divided into primary and secondary criteria. Primary criteria are those that constitute a successful project; the project will be unsuccessful if it does not meet these goals.
Answer:
The function of DNA is tied to its structure. ... The sugars and phosphates link the nucleotides together to form each strand of DNA. When two strands of DNA come together, base pairs form between the nucleotides of each strand. Nitrogenous bases pair together in the following way: A-T and C-G.
The cell membrane is selectively permeable, allowing only certain substances to pass through. Passive transport is a way that small molecules or ions move across the cell membrane without input of energy by the cell. The three main kinds of passive transport are diffusion, osmosis, and facilitated diffusion.
Answer:
The answer is A
Explanation:
The hydrosphere provides almost all the water at or near the earth's surface. It is important to the biological and geological processes as it is a continuous cycle of recycling water between the oceans and atmosphere.
