Answer:
(a) and (d) are correct
Explanation:
AIDS is a disease that's usually transmitted by sexual contact and breast feeding.
Paleontology deals with fossils and helps in learning the changes of living organisms in sequence.
Biogeography deals with the distribution of species across the mother earth.
Embryology deals with the study of the similarities and difference that exists in the embryos of different species or organisms.
Anatomy deals with the study of the similarities and difference that exists among different species or organisms.
<u>Explanation: </u>
As an organism dies, the remaining of these organisms will be buried in soil. These are fossils. Paleontology supports evolution with the information that are related to the fossils, footprints etc. With these we can study the evolution of organisms and also the changes they undergo. There are some technologies like radiometric dating that can be used for the determination of these rocks and fossils ages.
Charles Darwin suggested that the evolution of species were form their ancestor. Biogeography supports evolution by explaining about the distribution of different species over the earth. Embryology and Anatomy supports evolution by describing about the similarity and difference in the species of living organisms. Embryology deals with the embryos and anatomy deals with the structure.
The correct answer is "C."
mRNA stands for messenger Ribonucleic acid. The role of mRNA is to carry genetic information for the synthesis of protein from the nucleus after transcription.
After the transcription process is over, the mRNA leaves the nucleus and heads to the ribosomes in the cytoplasm where translation of this information takes place.
The ribosomes are the work bench of the cell. They receive the mRNA with its coded information, read it and translate it and with the help of tRNA (transfer RNA), amino acids are fetched from the cytoplasm and linked together to form the exact protein that was coded for on the mRNA.
Answer:
Explanation:
Matter can change form through physical and chemical changes, but through any of these changes matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed. This concept is called the Law of Conservation of Mass.
