Written above we have an example of a dihybrid cross. When two individuals that are heterozygous for both of the two traits we are observing cross we expect to get four different phenotypes in the ratio of <span> 9:3:3:1 :
9 dominant for both traits : (polka-dot tails and long eyelashes)
3 dominant for one, recessive for the other (polka-dot tails and short eyelashes)
3 recessive for the first one, dominant for the other (solid tails and long eyelashes)
1 recessive for both traits (solid tail and short eyelash)</span>
Answer:
As the frequency of respiration or breathing per minutes is resolved and made simple by using the kleiber's law. As it relates the metabolic rate of the organism and the animals mass.As "q°" is the organisms metabolic rate (or the rate at which metabolic reactions are done inside a cell)and "M" is termed as the mass of the organism.
As we have the following equation to find out or measure the frequency or respiration of an organism, which is as follows:
Explanation:
Now, due to the difference in size or more over the specific mass, "m" of the organisms body.
As the mass of a cow is about 720 kg, while the mouse's mass is about 30 kg in adult form. So, if we analyze both the values we get to know that the ratio of the frequency of a cow will be about 40 times more then that of the mice's metabolic rate in general form.
Answer:
C: Lipid A
Explanation:
Lipid A is a component of the endotoxin (also called the lipopolysaccharide) present in Gram-negative bacteria. The LPS has 3 component namely;
- the O-antigen: they are antigenic determinants and are the outer carbohydrate chains
- the core polysaccharide: forms the centre core of the LPS
- The Lipid A: forms the innermost part of the LPS and triggers acute inflammatory responses (e.g endotoxic shock) when released.
Upon detection of an endotoxin which forms the component of the outer membrane of a Gram negative organism (in exception to the Gram-positive bacteria called <em>Listeria monocytogenes</em>), the innate immune defense system (e.g macrophages and T-helper cells) are alerted to initiate elimination strategies towards the invading organism. Lipid A binds to the CD14/MD2 receptor on macrophages and monocytes which activates the nuclear factor kappa- light chain enhancer (NF-κβ). The activation of NF-κβ protein triggers the production of inflammatory cytokines which includes Interleukin-1 (IL-1), IL-12, IL-18 as well as the Tumor necrosis factor- alpha (TNF-α).
Inflammatory responses are as a result of the release of these cytokines which sometimes leads to shock and death of the host
Answer:
Atherosclerosis can affect any arteries in the body. Your doctor may recommend heart bypass surgery if your coronary arteries become so narrowed or blocked that you run a high risk of a heart attack. Your doctor will also recommend bypass surgery when the blockage is too severe to manage with medication or other treatments.
