Answer:
-During citric acid cycle or Krebs cycle, radioactive carbon will be first appear in citric acid
Explanation:
During cellular respiration, glucose is first converted into pyruvate molecules by the process of glycolysis. These pyruvate molecules go for oxidative decarboxylation, during which acetyl co-enzyme A (acetyl CoA) is formed along with removal of carbon dioxide.
The acetyl co-enzyme enters to the next step in cellular respiration or citric acid cycle or Krebs cycle. The first step of citric acid cycle is formation of citric acid by joining of acetyl CoA and oxaloacetate.
As citric acid is first molecule formed during citric acid cycle, radioactive carbon would be first appear in citric acid.
Pros:
It is (mostly) based on pyrethrine spray which kills the
insects rapidly.
It not poisonous to other animals.
It uses synthetic, natural spray which is safe to use because
it breaks down within 10 minutes.
Te technique can reach tall forests.
It can be used in closed spaces ( greenhouses, basements
etc).
Cons:
It requires windless circumstances ( which is mostly at
nights).
Breathing fog may cause respiratory and throat irritation to
some.
Answer: Maybe you think that snails, clams, mussels, squid, and octopods are very different. Yet, they are all in the same category of animals known as mollusks and are structurally similar. ... Mollusks usually, but not always, have a shell, which is secreted by a body wall called the mantle.
<span>Bacteria are tiny. A typical bacterial cell is just a few micrometres across (a few thousandths of a millimetre). The structure of a bacterial cell is different to an animal or plant cell. For example, they do not have a nucleus but they may have a flagellum. This is a tail-like part of the cell that can spin, moving the cell along.A unicellular organism is a living thing that is just one cell. There are different types of unicellular organism, including:
bacteria
protozoa
unicellular fungi
You might be tempted to think that these organisms are very simple, but in fact they can be very complex. They have adaptations that make them very well suited for life in their environment.Protozoa are unicellular organisms that live in water or in damp places. The amoeba is an example of one. Although it is just one cell, it has adaptations that let it behave a bit like an animal:
it produces pseudopodia (false feet) that let it move about
its pseudopodia can surround food and take it inside the cell
contractile vacuoles appear inside the cell, then merge with the surface to remove waste
You may be familiar with fungi from seeing mushrooms and toadstools. Yeast are unicellular fungi. They are used by brewers and wine-makers because they convert sugar into alcohol, and by bakers because they can produce carbon dioxide to make bread to rise.
Yeast have a cell wall, like plant cells, but no chloroplasts. This means they have to absorb sugars for their nutrition, rather than being able to make their own food by photosynthesis
Yeast can reproduce by producing a bud. The bud grows until it is large enough to split from the parent cell as a new yeast cell.</span>
