Answer:
<em>The correct option is C) T or t</em>
Explanation:
A heterogenous plant can be described as a heterozygous plant in which the alleles of a gene are different. For example, in the above question, the pea plant has one allele which is T and the other one which is t.
According to Mendel's law of segregation, the alleles assort independently at the time of gamete formation. Hence, there are equal chances that a gamete will carry T or t gene. Hence, the pollen grain will carry any one of the two alleles for the height gene.
Genetics is the study of how heritable traits are transmitted from parents to offspring. Humans have long observed that traits tend to be similar in families. It wasn't until the mid-nineteenth century that larger implications of genetic inheritance began to be studied scientifically.
Answer:
The correct answer is option a. "by trophallaxis with receiver bee".
Explanation:
Bees collect nectar from flowering plants, and when nectar foragers return to their colonies, they unload the nectar by trophallaxis with receiver bee. Trophallaxis is defined as the interchange of regurgitated liquids between insects, this is the process that occurs between the foragers and the receiver bees once they give the collected nectar to the hive.
Answer:
d. the 5' end
Explanation:
Capping is a co-transcriptional modification made to RNA in the nucleus after the first 25–30 nts are incorporated into the nascent transcript, which is synthetized in the 5' ---> 3' direction.
The cap consists of a methylated guanosine nucleotide added to the 5' end of the new mRNA transcript, and is important for several processes, which include:
- Protection of the mRNA from the attack of phosphatases and nucleases.
- Splicing of mRNA in the nucleus.
- Nuclear export of the mRNA to the cytoplasm.
- Cap-dependent protein synthesis.
