They can be spread around to make sure they can grow. Plants reproduce sexually not asexually they can also spread their seeds using insects.
<span>The lack of melanin tends to correlate with a lighter skin color. However, it also correlates with a higher susceptibility to receiving a sunburn. The more often a person burns, the more likely it is that a person will be susceptible to skin cancers later on in life.</span>
Answer:
The life cycles of all sexually reproducing plants follow a pattern of alternation between a haploid, sexual generation called gametophyte with a diploid, asexual generation called sporophyte.
This phenomenon of alternation between gametophyte (n) and sporophyte (2n) in the life cycle of a plant is called alternation of generations (Hofmeister, 1851).
Alternation of generations is of two types- isomorphic and heteromorphy. In isomorphic (or homologous) type both the alternating generations are morphologically similar, while in heteromophic (or heterologous) type of alternation of generations both the generations of life cycle are morphologically dissimilar.
Explanation:
Answer:
D.They contain a regulatory domain that is functional when removed from the DNA-binding domain.
Explanation:
Transcriptional activators are transcriptional factors that positively regulate transcription of the gene (increase gene transcription). They usually contain two functional domains:
- DNA-binding domain which interacts with DNA
- Activation domain which interacts with other proteins.
Mechanism of action of activators includes their binding to the enhancers (DNA sequences) and recruitment of RNA polymerase II to the promoter.
