Answer:
for number 2 its mosses or lichens
The type of cell division that takes place in the zygote of an organism exhibiting haplontic life cycle is meiosis
Answer:
The two types of pollution that are demonstrated in this real world example are:
- Toxic pollution and
- Sediment pollution.
Explanation:
- The new development that is being built is the main source that causes the pollution of stream through sediment process.
- Sediment is the process of carrying the waste through erosion and decomposition of plants and animals.
- Similarly the leaked oil antifreeze is highly toxic and hazardous to environment.
- The acid presence in the antifreeze onto the pavement is very harmful for the micro organisms as well.
D- the bird most likely eats nuts because it would need a longer beak to catch fish or dig up worms or other insects.
Answer:
E.bind to complementary regions of target mRNAs
A.The rate of accumulation of the polypeptide encoded by the target mRNA is reduced.
Explanation:
A researcher introduces double-stranded miRNA into a culture of mammalian cells and can identify its location or that of its smaller subsections experimentally, using a fluorescent probe. Sometime later, she finds that the introduced miRNA separates into single-stranded RNAs, one of which is degraded. Use this information to answer questions 1 and 2.
microRNAs (miRNAs) are a class of ∼22-nt noncoding RNAs(Ribonucleic Acids) that regulates gene expression in plants and animals. Precursor miRNA hairpins are mostly cut by Dicer in the cytoplasm to manufacture a double-stranded. when a double stranded miRNA separates into single stranded RNAs it is actually that it is attached to the complementary region of target mRNA
When she finds that the introduced miRNA separates into single-stranded RNAs, what other evidence of this single-stranded RNA activity can she find?
it means that:
The rate of accumulation of the polypeptide encoded by the target mRNA is reduced.
