Microtubules originate on the centre of the cell taking the positive end to the periphery of the cell, while the negative end remains turned to the centre of the cell. The melanosomes move along these microtubules using motor proteins desiganted kinesins and dyneins. The kinesins are responsible for moving the melanosomes to the positive end of the microtubule (periphery of the cell) generating dark-colored cells, whereas dyneins move the melanosomes to the negative end of the microtubule (centre of the cell) generating light-colored cells.
Answer:
a North American swamp or bog consisting of a mixture of water and partly dead vegetation, frequently covered by a layer of sphagnum or other mosses.
Explanation:
Answer:
- In glycolysis, glucose is split into two pyruvate and makes some ATP
- The Krebs cycle produces ATP, NADH and CO2
- NADH gives electrons to the ETC
- As electrons move down the ETC, a H+ gradient is made
- H+ pass through the ATP synthase to make ATP
Explanation:
This question is describing the processes involved in cellular respiration. Cellular respiration is the way through which living cells synthesize energy (ATP) by breaking down sugar. Cellular respiration involves three major steps: glycolysis, Krebs cycle, and oxidative phosphorylation (electron transport chain).
- Glycolysis is the process whereby glucose is broken down into pyruvic acid or pyruvate with the synthesis of net 2 ATP molecules.
- Kreb's cycle produces ATP, NADH and CO2.
- NADH is an electron carrier that donates electrons to the Electron transport chain (ETC).
- Electrons move down the ETC to produce a proton (H+) gradient
- The proton (H+) passes through an enzyme called ATP synthase to make ATP from ADP molecule.
Random distribution is the probable distribution pattern of opossums.
Explanation:
The opossums are the member of low density population. They are sparsely distributed because of the low number. There are troubles for them to find a mate.
Their habitat makes them solitary as they have flexible dietary habits. they are terrestrial animals living in burrows and are nocturnal.
They have random distribution pattern. The opossums are distributed in the population as random. The mates in opossums do not have choices of mates and the environment conditions in which they live are stagnant.(having no social life). Random interaction is seen in <em>species which do not have any social bonding</em> between the species of the animals or plants.
