Answer:
C. Phylogenetic niche conservatism
Explanation:
Based on the information provided within the question it can be said that the term that best explains these "living fossils" is Phylogenetic niche conservatism. This refers to the tendency that a specific species has for retaining certain traits from the ancestors. Which explains why the living "cycads" are nearly identical to fossils.
Answer and Explanation:
The manipulation of the gene is called genetic engineering. In genetic engineering, fragments of genes are cloned by leading the genes into the host cell. The advantage of using a prokaryotic host system in genetic engineering is that bacterial cells are used to produce commercially significant products. For example, human growth hormone helps to treat dwarfism, and human insulin production, which is used to treat diabetes. The bacterium P.putida is created by genetic engineering, which is used to break down petroleum products. Genetic engineering also carries some potential risks, such as transferring the selected gene into another speice, benefit one species can harm another speice. Therefore genetic engineering must be used in limit in prokaryotes. These limitations are also addressable in single-cell eukaryotic systems. Biologics-based therapeutic medicines such as a vaccine, gene therapies, and cell therapies known as bioproduction are produced. Medicines are so complex that they can only be formed in a living system. Biopharmaceuticals, value-added food, fuels, chemicals, antibiotics, and many other products are produced by bioproduction.
Answer:
The lizard will have a higher metablolic rate and it will have a higher activity level
Explanation:
Fishermen use minnows as bate, the minnows are stored in cold water for slower metabolic rate and a lower acivity level so that the minnows can last longer. It is the opposite of the lizard question
Answer:
Self-antigens are not recognized and attacked by the T cells.
Explanation:
In immunology, the antigens are those substances which are bound by the antibodies. The antigens can be originated from within the bodies, known as self antigens or from outside the body, known as non-self antigens. The immune system identifies and attacks non-self invaders or the foreign harmful objects present in the body. It does not attack the self-antigens under the normal conditions. This is due to the negative selection of T cells of the thymus.
