Answer:
Mutation is any change in the DNA sequence
It can be both disadvantageous or advantageous
Answer:
1- DNA replication: two identical DNA strands
2- Transcription: mRNA
3-Translation: proteins
4- Mitosis: two identical diploid somatic cells
5- Meiosis: four different haploid gamete cells
Explanation:
1- DNA replication: through the process of semiconservative DNA replication two identical DNA strands are created
2- Transcription: the process by which DNA becomes mRNA
3-Translation: the process by which mRNA becomes proteins
4- Mitosis: a parent cell will split into two identical diploid somatic cells, this process is used to replace old cells
5- Meiosis: a parent cell will split into four different haploid gamete cells, this process is used to create ovary/testes cells
Answer:
Sweating is under the control of the sympathetic nervous system, which orchestrates the body's reaction to stressful situations and emergencies. The sympathetic nervous system activates the sweat glands through the chemical messenger acetylcholine.
Answer: is heterozygous
Explanation: A hybrid is heterozygous which means that it has one dominant gene and one recessive gene. A dominant gene is a type of gene which has the ability to express itself phenotypically either in a homozygous or a heterozygous state. A dominant gene masks the effect of a recessive gene. A recessive gene is a type of gene that lacks the ability to express itself in a heterozygous state. It can only express itself outwardly in a homozygous state. It's effect is masked by the dominant gene is a heterozygous state.
<span>As there are many kinds of deserts, some hot, some cold even arid deserts are the classic hot deserts, but there are also cold and coastal deserts where temperatures do not get so high. The element common to all of these types of deserts, however, is their lack of rainfall. In that sense the rainfall is a characteristic that determines if it's a desert.</span>
