Answer:
there are four types of protein structure;
- primary
- secondary
- tertiary
- quatenary
Explanation:
A protein is a very large biological molecule composed of a chain of smaller molecules called amino acids. Thousands of different proteins are present in a cell, the synthesis of each type of protein being directed by a different gene.
Determining the process by which proteins fold into particular shapes, characteristic of their amino acid sequence, is commonly called "the protein folding problem", an area of study at the forefront of computational biology. One approach to studying the protein folding process is the application of statistical mechanics techniques and molecular dynamics simulations to the study of protein folding. Protein folding enables them to perform different diverse functions.
Protein have a three-dimensional structure that enables them to perform diverse functions like transsport,structural support as building blocks and metabolic regulators as enzymes and hormones.
Answer:
They both had a tail as an embryo.
Explanation:
Both human and dogs have tail as an embryo. Temporary tail-like structures are present in the human embryo. These tail like structure develop around the fifth or sixth week of gestation, having about 10 to 12 vertebrae and removed when it reached to its full development stage while on the other hand, tail present in dog's embryo also developed with time and we can see when the dog baby is fully formed.
The correct answer is cold fronts
Answer:
The given statement is true.
Explanation:
The enactment of the Environmental Policy Act or the EPA in 1969 was done to monitor the issues of the environment that took place in the 1960s. It was the major and the primary law, which was postulated at that time to solve environmental issues in the United States. The enactment of the EPA law was done for various reasons, some of which are as follows:
1. To better the health of human beings.
2. To generate harmony between nature and humans.
3. To encourage efforts to reduce destruction to the environment.
