Answer:
The correct answer will be option- adhere to cell surfaces.
Explanation:
The bacterial fimbriae are the cellular appendages which help the bacteria to attach to a substratum. This attachment property of the fimbriae is due to the presence of a protein called adhesins.
The fimbriae are also known as the attachment pilus of the bacteria which are thinner than a flagellum. The bacteria posses many fimbriae to adhere to the surface like to receptors, another bacteria or any other substratum.
Thus, option- adhere to cell surfaces is the correct answer.
Answer:
Since cells are utilized at a point or the other in the organism life we can say the general concept of life-is-cellular holds and abandon the cell membrane partitions notion
Explanation:
where the metabolic processes occur that keep the organism alive is the cellular level of an organism (the general concept of life-is-cellular)
Answer:
2.Less than 73% of the populations would have only one allele present.
Explanation:
The two alleles chosen do not affect the fitness of flies in the lab environment, so Kerr and Wright could be confident that if changes in the frequency of normal and forked phenotypes occurred, they would not be due to natural selection.
Using a larger breeding population would not be expected to alter the outcome of the experiment.
Options for the question have not been give. They are as follows:
A. P site
B. A site
C. E site
D. directly to the cytosol
E. exit tunnel
Answer:
C. E site
Explanation:
Translation is the process by which mRNA is converted into polypeptide chain. Translation machinery has three binding slots for tRNA : A, P and E. Any incoming tRNA encounters A, P and E site in that order.
When a new tRNA (#1) carrying the next amino acid (here, lysine) comes, it enters the A site. Peptide bond is formed between lysine and the already existing amino acid on the growing polypeptide chain on the preceding tRNA (#2). Once lysine is added to the polypeptide chain, the entire chain moves to tRNA #1 which makes tRNA #2 empty. Meanwhile, the machinery moves forward. As a result, tRNA #1 slides to P site and tRNA #2 slides to E site. The A site is empty now and can receive another tRNA.
Answer: Plants use Carbon Dioxide to produce sugars and energy, so you could expect the high-energy sugars to be depleted as the sugars are used to produce energy, and the sugars cannot be replaced as fast as they are being used.
