Answer:
By using sequence information from covalently attached nucleotides.
Explanation:
TRNA presents an anticodon sequence to required sites as a physical bridge with elongation factors (proteins) to form a connection between mRNA and ribosome and encode amino acids to ultimately form specific protein structure. tRNA carries out this activity by using sequence information from covalently attached nucleotides.
Answer:
D. Transport of oxygen through a placenta to a fetus.
Explanation:
Zygotes are fertilized egg cell, zygotes aren't produced in the ovaries but ovums or egg cells are produced in the ovaries. So option A is false.
Fertilization is internal not external in human. Option B is wrong.
Production of milk happens in the mammary gland (the breast) not in the reproductive system. Option C is false.
Transport of oxygen through a placenta to a fetus. The placenta is a vascular organ which is implanted in the wall of the uterus (a part of the female reproductive system) and links to the foetus through the umbilical cord.
Answer:
I Think so.
The enzymes can contain fewer amino acids
Providing long-term control over the body's internal conditions
Keeping conditions within a normal range
Adjusting the "set point" for body temperature based upon level of activity
Answer:
yellow; epistasis.
Explanation:
Epistasis may be defined as the phenomena in which the physical constitution of the individual gets influenced by the presence or the absence of the different genes.
The different types of epistasis are dominant epistasis, recessive epistasis and duplicate epistasis. The dog has yellow fur as it shows the case of recessive epistasis in which the recessive gene modifies the expression of black fur pigmented gene.
Thus, the correct answer is option (b).
