Gametes are an organism's reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each
Answer:
D. Finding the possible traits of the offspring of two plants whose genes are known
Explanation:
Punnett Squares are used by applying both of the genes of the parent organisms to find the possible traits of the offspring.
Answer:
B. half, half
Explanation:
When a diploid organism has one dominant allele and one recessive allele of a gene, it is said to be heterozygous for the gene. During gamete formation, random segregation of homologous chromosomes leads to separation and random distribution of alleles of a gene in separate gametes. Therefore, a heterozygous individual for a gene forms two types of gametes: 50% of the gametes with dominant allele and rest 50% with the recessive allele.
For instance, an individual with an "Aa" genotype will form 50% gametes with an "A" allele and 50% gametes with an "a" allele.
The difference between the concentration of a substance between two areas is called the concentration gradient. This concentration gradient between a cell and its environment shows a difference resulting in the simplest form of transport called the passive transport. It is the movement of substances from a region of its higher concentration to a region of its lower concentration along with the concentration gradient across a semi permeable membrane.
Passive transport includes diffusion, facilitated diffusion, osmosis and filtration. All these processes are involved in various metabolic activities of the cell. Some of the examples are the movement of water molecules, nutrients, elimination of waste substances, exchange of gases and important life processes like digestion, respiration, excretion, transmission of nerve impulses and others depend on different types of passive transport. On elimination of concentration gradient between a cell and its environment, all the metabolic activities of the cell are inhibited and the cell dies.
