Answer:
1. Nucleus
2. RNA polymerase
3. mRNA
Explanation:
Transcription is the first process of gene expression in which a DNA strand is used to synthesize a mRNA molecule. In the process of transcription, which occurs in the NUCLEUS, an enzyme called RNA polymerase binds to the DNA molecule.
The enzyme separates the double stranded DNA and the uses the complementary base pairing rule i.e. A-U, G-C to synthesize a mRNA molecule that is complementary to the DNA template strand. This newly built mRNA molecule then leaves the nucleus and enters the cytoplasm of the cell for translation to occur.
Answer:
Explanation:
Geobacter is a microbe use in clean technology to oxidize compounds such as metals.
Hydrocarbonoclastic bacteria (HCB) are bacteria that function majorly in the biodegradation of oil hydrocarbons in marine and other environments.
Actinomycetes is a microbe use in the production of antibiotics and recycling of organic matter in the soil.
Thiobacilli are bacteria that have the ability to obtain energy from the oxidation of sulphur and reduced inorganic sulphur bonds. They are Majorly acidophilic or are called acid tolerant bacteria and they are capable of fixing able CO2.
Answer: The correct answer for the first question is- B) Mechanical.
Adaptation can be described as a process of change in an organism over time that facilitates its survival in the changing environmental conditions. It results due to mutation or genetic change in the individual that gives a benefit to the organism. It exhibits change in structure ( like succulent plants in desert), function, or behavior.
Mechanical is not a type of adaptation as it deals with movement of objects.
The correct answer for second question is- C) Variations.
Variation among organisms in a population results from change in the genetic material or their genetic sequences. Change at the genetic level is thus reflected in the phenotypes ( like different color of feathers in birds).
Thus, difference is in the feather color reflects variations.
Answer:
D.
Both the femur and humerus bone have what's called 'spongy bone' inside them and hollow spaces full of yellow and red bone marrow. Additionally, both bones do not attach to the axial skeleton but rather attach to the pelvic or hip bones; while they are both strong bones, they are not made of only compact bone but are made of 'spongy bone' inside them. Lastly, they do not protect any organs but rather allow for movement. D, They both have hollow spaces filled with bone-generating cells, is the best answer in this case
