Answer:

Astronomers have always assumed that Uranus must have been knocked onto its side by a collision. Now a new idea suggests that the planet's remarkable tilt could have another explanation.

One of the great mysteries of our Solar System is why Uranus is tilted on its side. Surely, if the solar system formed from the same rotating cloud of dust and gas, then all the bodies within it should rotate in the same way. And yet Uranus’ axis of rotation lies at 97 degrees to the plane of the solar system.

Answer:

Give at least 3 reasons why viruses are considered non-living and therefore NOT classified into the Linnaean system of life.

Viruses as we know that they are micro-organism but they are not produced from cell

Viruses does not grow rather undergo replication by multiplying into several number within minutes

also they rely on host energy as they could not produce energy needed for their usage.

Explanation:

Every living organism are made up of cells which makes it the fundamental unit of life where virus does not fall into such category, Growth is an essential characteristics of every living organisms, viruses only replicate rather they does not undergo growth.

Transport of a compound across a cell membrane (down a concentration gradient) was measured at several concentrations. The presence or absence of ATP had no effect on the transport of this compound. ... Why are the lipid bilayers in cells called "selectively permeable"? They are permeable to some substances but not others.

Explanation:

B. Lactic acid is produced from lactobacilli as the starter undergoes fermentation

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 (pyruvic acid) is produced in the cytoplasm via glycolysis- it is also used as an electron acceptor in a process called fermentation. In lactic acid bacteria, the pyruvate produced is directly transferred to lactate (a form of lactic acid) producing NAD+.

Further Explanation:

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.

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

What is the DEPENDENT variable in this experiment? (Hint: What depends on the independent variable?)

Nutka1998 [239]

Could you give more information? For the most part, the dependent variable is what you’re recording. For example, if you wanted to see how plants would grow in different conditions, plant height would be the dependent variable. The height DEPENDS on the condition it was grown in. Hope this helps!
