Answer:
The correct answer is option - a virus.
Explanation:
Viruses are the infectious agents that are neither considered living nor nonliving organisms. The viruses possess the genetic material enclosed in the capsid made up of the proteins.
Genetic material or the genome of the viruses could be the DNA or the RNA as single or double-stranded forms. The viruses with RNA as genetic material termed as the adenoviruses such as tobacco mosaic viruses and HIV and others.
Thus, the correct answer is option - a virus.
The answer is; D
The porous rock is able to absorb water from precipitation. The water resides in the pores of the rock. The impermeable rock later, which does not allow water to pass through it, allows more water to hold in the porous rock and making the local water table to rise. The water in the porous rock, therefore, can be accessed through wells or a water spring can develop.
Answer:
Treating the affected area with an alkaline solution or substance such as baking soda.
Explanation:
Neutralization Reaction:
- When an acid and an alkali react chemically, they form water and a corresponding salt. This reaction called the neutralization reaction.
- acid + base (alkali) → salt + water
- E.g HCl + NaOH → NaCl + H2O
- The formic acid that the ant injects can be neutralization by application of an alkali.
- In order to prevent a serious allergic reaction, antihistamines must also be administered.
Answer:
Dominant allele does not completely conceal recessive allele.
Snapdragon with genotype Rr (R being red and r being white), would have a phenotype of pink flowers.
Explanation:
Incomplete dominance is where a dominant allele is not able to completely conceal a recessive allele, usually leading to a phenotype which appears to be a combination of the two.
For example, in snapdragons:
The allele for red flowers (R) is dominant over the allele for white flowers (r). Let's say a snapdragon flower had the genotype Rr, one allele for red flowers and one for white. In the case of 'normal' dominance the dominant red flower allele (R) would mask the effects of the recessive white flower allele (r), resulting in the phenotype (outward observable characteristics) of having red flowers.
However here in the case of incomplete dominance, the dominant allele would not be able to fully cover up the effects of the white flower allele, meaning that both colors (red and white) are expressed in the phenotype, resulting in pink flowers.

The respiratory system works directly with the circulatory system to provide oxygen to the body. Oxygen taken in from the respiratory system moves into blood vessels that then circulate oxygen-rich blood to tissues and cells.
