C. Water seeps into spaces between rocks.
The smallest living unit is actually a cell. An organelle is an organ inside of a cell. An organelle would not be considered alive because it can not survive without the other organelles. Whereas, a cell can survive without other cells.
1. Genetics and environment influence the trait as it depends upon the adaptation made according to availability and environment.
2. Traits are passed onto either parents after fertilization when 2 genes from either parent is received.
3. Dominant trait is responsible for the phenotype of the individual.
4. The expression of gene is seen by the phenotype expressed depending upon the environmental factors.
Explanation:
The food preferences are based on the traits adapted over the time for digestion and method of eating due to natural selection. The occurrence of beneficial trait for digestion become common in the population as these traits are transferred for better survival and evolution.
The traits in an organism is passed on from parents. During fertilization one allele from each parent is passed onto the progeny. 2 alleles together are called gene. In the process of meiosis only one chromosome is present in germ cell hence no homologous chromosome thus only one allele for the trait is present in each parent.
The alleles of dominant trait mask the effect of recessive alleles during phenotype expression. According to law of complete Dominance the dominant trait gets expressed and recessive trait do not get expressed.
The temperature, external environment, chemicals, light factor, diet etc influences the expression of genes in certain organisms. The effect of these can be seen on the phenotype of the organism.
Google would have the best answer choice for this question. sorry i couldnt help you.
Answer:
The correct answer is "receptors".
Explanation:
Virus infect and reproduce by recognizing specific receptors in their host cells. Virus-receptor binding is highly specific, this is the reason why some virus can infect only certain animals or plants at specific tissues. If the virus that causes avian flu attaches only to the cells of the lower part of the respiratory system, it is very likely that these cells have specific receptors that are not present in the upper part of the respiratory system, receptors that the viruses recognize.
