Answer: molecular size or weight of the agent.
Explanation: The smaller the size, the faster it can diffuse out and the greater the rate of diffusion.
Answer:
Genetic code
Explanation:
Genetic code refers to the set of rules by which the information encoded in the genetic material is translated into the proteins. The genetic code is present on the genes in the form of triplets of nucleotides called codons which specifies the specific amino acid.
The codon system of the genetic code rules allows the 4 different nucleotides to form specific amino acids by the combination of the four different nucleotide in the triplets.
Thus, Genetic code is the correct answer.
The correct answer is A. Thyroid
Explanation:
In biology, a gland refers to a type of structure composed by cells whose main function is to synthesize substances especially hormones. This includes the thymus gland that is composed of two lobes and is located near the heart; the anterior/posterior pituitary gland that is located at the base of the brain and it is one of the smallest glands; the pancreas that is located in the abdomen and the thyroid that as the thymos is composed of two lobes, secrets different hormones and it is located in the neck/throat. Considering this, the gland described is the Thyroid because this is the only one located in the throat and also this is composed of two loves.
The correct answer is the option (D) Both are not a mammal, are multicellular, and are heterotrophic.
Keys in biology are used to identify the different species based on the easily identifiable features of the organism. A dichotomous key consists of a series of questions on features like habitat, mode of nutrition, class to which they belong and other features, with each question having two answers describing the characteristic features of an organism. The series of questions begin with a broader characteristic feature becoming narrow gradually and helping in the identification of the organism.
Both the house sparrow and a cobra cannot synthesize their own food and depend on other organisms for food. Hence they are heterotrophic. They are multicellular in nature. A cobra belongs to the class Repltiles and a house sparrow belongs to the class Aves. Thus, a house sparrow and a cobra are similar to each other in being multicellular, heterotrophic and not belonging to the class mammals.
Because the species are territorial, no two species can be in the same niche at any given time
