How does a capsule help certain bacteria evade detection by the immune system? How does a capsule help certain bacteria evade de

tection by the immune system? The capsule is composed of polysaccharides that are similar to those found in the host; thus, the immune system does not recognize it as foreign. The capsule makes the bacterium too sticky to be phagocytosed by the immune cells. Capsules have the ability to destroy antibodies secreted by the immune system. Capsules allow the bacteria to stick together, creating a larger mass that is too big for immune cells to engulf.

Which of the following organelles and functions are NOT correctly related? A. vacuoles--storage B. Golgi apparatus--secretions C
Dmitry_Shevchenko [17]

Answer: Option E) endoplasmic reticulum--photosynthesis

Explanation:

The endoplasmic reticulum (ER) has nothing to do with photosynthesis.

Rather the ER, is responsible for the transport of materials within the cytoplasm, while the chloroplast found in plant cells is responsible for the process of photosynthesis

Thus, the endoplasmic reticulum is not correctly related to photosynthesis.

What are the reactants and products at each stage of cellular respiration? Including amounts.
drek231 [11]

Explanation:

In all eukaryotic cells mitochondria are small cellular organelles bone by membranes views 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).

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

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.
  • The 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.

PLS HELP What are three types of natural selection that act on variation?
zhuklara [117]

Stabilizing selection, directional selection and disruptive selection are the three types of natural selection.

What are these types of selection?

Natural selection is the process wherein organisms get better adapted to their environments and tend to survive and produce more offsprings. It is basically a mechanism of evolution which favors those organisms that can better adapt to their environment.

Directional selection: this theory states that an extreme phenotype (a characteristic or trait) is favored over other phenotypes and this causes the allele frequency to shift in favor of the extreme phenotype over time. A particular trait, if favorable, will be expressed in the population at the most beneficial frequency.

Stabilizing selection: in this type, meaning a non-extreme trait is favored instead of one of the two extreme traits. Stabilizing selection is said to be the most common mechanism for natural selection, because most traits do not change drastically over time.

Disruptive selection: This selection is bimodal. It favors both of the extreme traits in a population.

So therefore, stabilizing selection, directional selection and disruptive selection are the three types of natural selection.
