How was the knowledge of ecological succession applied to the reclamation of land damaged due to mining?

Mandarinka [93]

After mining, to reclaim the land, the depression is filled with rocks then the top is filled with loosely graded soil. Introduction of early succession plants is important before big trees can grow. The early succession plants help in the breaking down of the rocks into soil hence making the topsoil deeper to support trees.

Compare the properties of the parent and daughter cells in mitosis and meiosis and explain the reason for any differences.

MariettaO [177]

1. Mitosis takes place within somatic cells (cells that make up the body). Meiosis takes place within gamete cells (sex cells).

2. One single division of the mother cell results in two daughter cells. Two divisions of the mother cell result in four meiotic products or haploid gametes.

3. A mitotic mother cell can either be haploid or diploid. A meiotic mother cell is always diploid.

4. The number of chromosomes per nucleus remains the same after division. The meiotic products contain a haploid (n) number of chromosomes in contrast to the (2nd) number of chromosomes in the mother cell.

5. It is preceded by an S-phase in which the amount of DNA is duplicated. In meiosis, only meiosis I is preceded by an S-phase.

6. In mitosis, there is no pairing of homologous chromosomes. During prophase I, complete pairing of all homologous chromosomes takes place.

7. There is no exchange of DNA (crossing-over) between chromosomes. There is at least one crossing-over or DNA exchange per homologous pair of chromosomes.

8. The centromeres split during anaphase. The centromeres do separate during anaphase II, but not during anaphase I.

9. The genotype of the daughter cells is identical to that of the mother cells. Meiotic products differ in their genotype from the mother cell.

10. After mitosis, each daughter cell has exactly same DNA strands. After meiosis, each daughter cell has only half of the DNA strands

A blockage in _________ vessels would most likely cause a myocardial infarction in the lateral right side of the heart

Kobotan [32]

Answer:

Coronary Artery

Explanation:

A blockage by blood clot formation is coronary artery called as thrombus reduces the blood flow to the heart. The reduced blood flow causes the heart to dysfunction and the myocardial infarction occurs. Heart tissue can sustain serious damage upon such a shock.

There is an error in the above model.

ollegr [7]

ATP hydrolysis is the lysis of the molecule mediated by water. It releases a phosphate group and energy. It is a reversible reaction. (a) Reversible ATP hydrolysis. (b) added energy on the left and released energy on the right.

------------------------

ATP is a significant molecule involved in many of the cellular metabolic routes. These metabolic processes can either form it or break it.

ATP provides energy to many different functions in the organism.

ATP means adenosine tri-phosphate. It is composed of adenosine (an adenine plus a ribose), and three phosphate groups.

Note: you can also find adenosine Diphosphate (two phosphates) and adenosine monophosphate (one phosphate).

Oxygens from the phosphate groups only have a single bond to phosphate (there are no hydrogen bonds).

These single bonds, known as phophoanhydrid bonds, have a negative charge and tend to repel each other, making the molecule unstable.

So phosphate groups repel each other, and a considerable amount of energy is applied to keep them united. So phophoanhydrid bonds are high energetic bonds.

The forces that keep the phosphate groups together accumulate potential energy.

If these bonds are broken, part of this potential energy would be released.

When talking about breaking the molecule, we are referring to ATP hydrolysis. And the released energy is used in different cellular processes that require energy.

ATP Hydrolysis is the molecule lysis mediated by a water molecule.

ATP + H₂O ⇄ ADP + Pi + Energy

Pi is the released inorganic phosphate group.

This is a reversible reaction, meaning that the ADP can go back to ATP.

ADP + Pi + Energy ⇄ ATP + H₂O

(a) What is this a model of?

This model represents the reversible ATP hydrolysis.

In the superior part of the image, we can see an ATP molecule composed of adenine, ribose, and three phosphate groups. The yellow star behind represents the accumulated energy.

When ATP hydrolysis, it loses a phosphate group and part of the energy that was keeping this group in the molecule.

An ADP is composed after hydrolysis. We can see this molecule in the inferior area of the image.

ADP molecule is composed of adenine, ribose, and two phosphate groups.

Because hydrolysis is a reversible process, by adding a new phosphate inorganic group and energy, we can get a new ATP.

(b) Explain how you would change the model to make it correct?

What is wrong with this model is that instead of showing released energy during the hydrolysis process, it shows energy added to the reaction.

In the same way, instead of showing added energy to the reversible reaction, it shows released energy.

Added energy and released energy must be changed.

Added energy should be on the left
Released energy should be on the right
