The coarse adjustment knob moves the stage up and down for focusing.

When using a microscope one should use the coarse adjustment and the low power objective to locate and observe a specimen on a slide.

The coarse adjustment of a microscope should be used with the low-power objective, but not with the high power objective.

Crossing over between non sister chromatids during meiosis is significant in heredity

suter [353]

Crossing over is the main event in meiosis and heredity as it leads to genetic variation.

<h3>What is genetic variation?</h3>

Genetic variation is the changes that take place in the genes of individuals that can lead to the formation of new characters.

it generally occurs in meiosis specifically during crossing over.

Thus, it can be concluded that crossing over between non-sister chromatids during meiosis is significant in heredity as it leads to genetic variation.

Habitat loss is contributing to the permanent loss of species, the weakening of ecosystems, and is impacting the overall health of the planet.

Example:

While tree-clearing is a significant cause of habitat loss in Australia, other major contributing factors include altered bushfire frequency and the introduction of pest species that make habitats unsafe for native species or outcompete them. Meanwhile, on the Great Barrier Reef, the impacts of human-induced climate change are altering the habitats of corals, leading to large-scale coral bleaching. Over time, destruction of such habitats leads to reduced biodiversity and weakening of the Earth’s ecosystem.

A cell come a certain organism has 64 individual, or 32 pairs, of chromosomes. Which of these can you draw?

Dmitriy789 [7]

Answer:

B. The cell cannot be a human

Explanation:

Humans have 23 pairs of chromosomes, or 46 individual chromosomes. Mutations in humans usually cause there to be a single extra chromosome, or a single missing chromosome. A mutation would not cause there to be 64. So, A cannot be true. Prokaryotic cells usually have one chromosome, not 64, so C cannot be true. D cannot be assumed as you cannot tell if there is uncontrolled cell growth. Therefore, the answer would be B.

GalinKa [24]

Answer:

1. B. NADH

2. B. hydrolysis of ATP.

3. C. ATP is produced from protein.

4. Option C.

5. Option C. Oxygen

6. Option D. Glucose.

7. Carbondioxide.

8. Metabolism.

9. Electron carriers.

10. Electrons.

Explanation:

Cellular respiration is a series of metabolic processes that break down sugars or food to produce energy. ATP is the cellular energy produced during cellular respiration. Cellular respiration requires oxygen which is also called aerobic respiration. There are stages of cellular respiration and they include; glycolysis, pyruvate oxidation, Krebs cycle or citric acid and oxidative phosphorylation. During cellular respiration, glucose is broken down into carbondioxide and water. Along the way, ATP is produced from the processes that transform glucose.
