Biology
1 answer:
viva [34]2 years ago
5 0
Phagocytosis, process by which certain living cells called phagocytes ingest or engulf other cells or particles. The phagocyte may be a free-living one-celled organism, such as an amoeba, or one of the body cells, such as a white blood cell.

Alex Ar [27]
A geographic range of an animal can give us a lot of information, for example:

- the climatic conditions it adapted to: does it like wet or a dry environment? Does it like heat?
-<span>the parasites/predators that these butterflies may encounter - by knowing who else lives in that area, we can guess what </span>can threaten the butterflies
-similarly, we can guess what food is available to the butterflies.

Which describes the process of fermentation?
pav-90 [236]

Explanation:

<u>anaerobic process that restores NAD+ supply</u>

<u></u>

Within cells, aerobic respiration may not occur due to several factors:

  • - a lack of inorganic,  final electron acceptors
  • -incomplete or lack of a complete electron transport system
  • -missing genes for enzymes within the Kreb's cycle

Thus, they utilize other means for the generation of energy in the form of ATP and to replenish NAD+ an oxidized form of NADH, the main electron carrier in glycolysis.  Pyruvate is produced  in the cytoplasm via glycolysis- it is also used as an electron acceptor in a process called fermentation.

Further Explanation:

overall: C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≈38 ATP

In all eukaryotic cells mitochondria are small cellular organelles bound by membranes, these make most of the chemical energy required for powering the biochemical reactions within the cell. This chemical energy is stored within the molecule ATP which is produced. Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’ or Citric acid cycle via the oxidization of pyruvate( through the process of glycolysis in the cytoplasm).

Oxidative phosphorylation describes a process in which the NADH and FADH2 made in previous steps of respiration process give up electrons in the electron transport chain these are converted it to their previous forms, NADH+ and FAD. Electrons continue to move down the chain the energy they release is used in pumping protons out of the matrix of the mitochondria.

This forms a gradient where there is a differential in the number of protons on either side of the membrane the protons flow or re-enter the matrix through the enzyme ATP synthase, which makes the energy storage molecules of ATP from the reduction of ADP. At the end of the electron transport, three molecules of oxygen accept electrons and protons to form molecules of water...

  • Glycolysis: occurs in the cytoplasm 2 molecules of ATP are used to cleave glucose into 2 pyruvates, 4 ATP and 2 electron carrying NADH molecules. (2 ATP are utilized for a net ATP of 2)
  • The Citric acid or Kreb's cycle: in the mitochondrial matrix- 6 molecules of CO2 are produced by combining oxygen and the carbon within pyruvate, 2 ATP oxygen molecules, 8 NADH and 2 FADH2.
  • The electron transport chain, ETC: in the inner mitochondrial membrane, 34 ATP, electrons combine with H+ split from 10 NADH, 4 FADH2, renewing the number of electron acceptors and 3 oxygen; this forms 6 H2O, 10 NAD+, 4 FAD.

What can scientists accomplish by applying recombinant-DNA technology?
Bogdan [553]

Answer:

- production of vaccine for disease prevention

- production of genetically modified crops

Explanation:

Recombinant DNA is a special type of DNA that has been infused with a foreign gene of particular interest.

With recombinant DNA technology, scientists can study different proteins and see how they can be used for therapy in the area of medicine. <em>The technology has been used to produce several vaccine in the prevention of diseases.</em>

In addition, recombinant DNA technology has been useful in agriculture to produce <em>genetically modified crops with desired traits such as resistance to pests/diseases and high yields.</em>
