Which was a conclusion of griffith's work with streptococcus pneumonia?

Despite prokaryotic microbes being invisible to the naked eye, Rob Dunn and his team understood that they were likely to find su

Nadusha1986 [10]

Answer: c. ability to become highly abundant in most ecosystems.

Explanation:

The prokaryotic microbes are small tiny creates which remain invisible to the naked eyes. These require special instruments to be observed. The reproduce at a considerable rate and they have the tendency to spread all over the world in a short time. Their reproduction is simple that is division of the parent cell into daughter cells. This facilitates their abundance in most ecosystems initiating with colonization in living organisms.

The given situation indicates that rapid reproduction facilitates the microbes to become abundant in the ecosystem.

If ethyl alcohol contains almost as much energy as the original pyruvic acid, what can you infer about the efficiency of ferment

shusha [124]

Explanation:

Fermentation has a comparatively low efficiency as it produces the same amount of energy, whereas aerobic respiration produces up to 38 molecules of ATP .

Aerobic 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).

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.

Net production of ATP in fermentation: 2 ATP
Net production of ATP in aerobic respiration ≈38 ATP

Further Explanation:

overall in aerobic respiration: 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 is one event that may occur during Telophase I?

Mumz [18]

The main events of telophase include a reappearance and enlargement of the nucleolus, enlargement of the daughter nuclei to their interphase size, decondensation of the chromatin resulting in a brighter appearance of the nuclei with phase-contrast optics, and a period of rapid.

A student will measure and record the growth (in height) of two flowering plants every other day for 20 days. Each plant will re

zepelin [54]

Answer:

The correct answer is -

the independent variable - if fertilizer added or not,

the dependant variable - the height of the plant and

the standardized variable - 200ml water

Explanation:

In this study, the student wanted to see the effect of the fertilizer on the growth of the plant so the independent variable is the treatment of the fertilizer as manipulated or the independent variable is the factor which is affected or changed purposely during an experiment while other variables remain constant.

The dependent variable is the factor that is based or depends on the independent variable and measured to see the effect which is the height of the plants in this case.

The standardized or the control variable is the variable that remains constant throughout the experiment, 200 ml water treatment is the control variable in this experiment.
