Atom refers to a tiny particle, which is the basic building block of all the substances and whose properties determine the characteristics of an element made up of only of those atoms.
All the living and nonliving matter in this world are made up of atoms and elements. Everything in the universe is matter, and matter comprises elements. Some of the elements are important to living things.
Elements are formed by atoms, and atoms comprise protons, electrons, and neutrons. The number of protons in an element's atom signifies the identity of the element.
Correct answer: D
A pollen is where male gametes are produced and so the number of chromosomes, as we are talking about gametes, is n. This means that the grain of pollen will only have a copy of each gene, and therefore only one allele for each gene - one S, and one T or t. So, the possible combinations are ST and St.
For a monohybrid cross, you are crossing two alleles with two alleles. in a dihybrid cross, you are crossing four alleles with four alleles.
Answer:
Behavior genetics.
Explanation:
Genetics may be defined as a branch of biology that studies the inheritance and variation of the inherited characters. Mendel is known as the father of the genetics.
Behavior genetics may be defined as the field of the scientific research that uses the genetic methods to investigate the behavioral differences in the individual. This genetics uses the limits of genetics and environmental impact on the individual's behavior.
Thus, the answer is behavior genetics.
