Answer:
Ecologists
Explanation
often estimate the size and density of populations using quadrats and the mark-recapture method. A population can also be described in terms of the distribution, or dispersion, of the individuals that make it up. Individuals may be distributed in a uniform, random, or clumped pattern.
Answer:
The cell spend most times in the interphase
The cell spend short time in the anaphase.
Explanation:
Interphase is the longest phase in cell cycle because it is a phase where series of cell of divisions take place
because there is need for the cell to grow, replicate or duplicate it's DNA and also make preparations for cell division.
Anaphase is the shortest phase because during anaphase, the sister chromatids become pulled apart to other opposite ends of the cell.
Viruses are not alive. Although they sort of “hack” a host’s cells and reproduce, they do not breathe or move on their own. A virus will sit on a counter forever if it’s untouched. Viruses are spread by physical contact, not because they can move around on their own.
Although viruses can attack and hack, and use your cells to reproduce, they are programmed to do so.
Cells are very much alive, while viruses are not.
Answer:
Option b oxaloacetate is the right one.
Explanation:
There are major eight steps in TCA cycle. Oxaloacetate plays a pivotal role in <u>first and eight step</u>s of cycle.
Step 1. In the first step of the citric acid cycle, acetyl CoA joins with a four-carbon molecule, oxaloacetate, releasing the CoA group and forming a six-carbon molecule called citrate.
Step 8. In the last step of the citric acid cycle, oxaloacetate—the starting four-carbon compound-is regenerated by oxidation of malate. Another molecule of NAD+ is reduced to NADH in the process.
The process is ocurring by steps, starting with depolarization.
1- Na+ permeability > K+ permeability
2- Vm (membrane potential) approaches ENa+ (quilibrium potential for potassium)
3- K+ permeability > Na+ permeability
4- Vm (membrane potential) approaches EK+ (quilibrium potential for potassium)
