Answer:
d Meth-Arg-Asn-Pro-Leu-stop
Explanation:
This question is describing the processes of transcription and translation of protein synthesis. Transcription is the synthesis of mRNA from DNA while translation is the synthesis of amino acid from mRNA. In this question, the following DNA sequence is given:
TAC/GCA/TTA/GGC/AAC/ACT
- Following the complementary base pairing rule i.e A-U, G-C, T-A etc, the following mRNA transcript will be produced after transcription:
AUG/CGU/AAU/CCG/UUG/UGA
- Using the genetic code, the following amino acid sequence will be produced from the above mRNA sequence after translation:
Methionine/Arginine/Asparagine/Proline/Leucine/STOP.
Answer:
The correct answer is "Nitrogen will only become available to other, nearby plants when the nodules or the nitrogen-fixing plant itself dies".
Explanation:
Nitrogen fixing bacteria maintain a symbiotic relationship with plants. Bacteria performs nitrogen fixation providing the plant with ammonia, while bacteria has a safe place and nutrients to prosper. This relationship is very intimate because it occurs at the root hair of the plant at structures called nodules. Therefore, nitrogen will only become available to other, nearby plants when the nodules or the nitrogen-fixing plant itself dies
Answer: A. a molecule that reacts specifically with an antibody or immune lymphocyte.
Explanation:
An antigen is a foreign body that enters inside the other host body it initiates an immune response. As a result of action of immune response the antibodies are produced. The antibodies are the proteins which fights against the antigen. The antibodies are produced by the white blood cells or lymphocytes. The antigen can be in the form of chemical agents, pollen, pathogens such as bacteria and viruses.
D: Both are not a mammal, are multicellular, and are heterotrophic
True. This is because they form the lowest parts of the food chain. These invertebrates at young stages are generally exposed to the harsh environments around them. Being organisms that have not developed their mechanisms for protection these invertebrates will be subject to bigger animals and will serve as an easy prey. These invertebrates can be easy prey to larger organisms like birds and frogs, that mostly feed on insects and soft organisms. The saying, "survival of the fittest," is always true when it comes to the ecosystem.
