7. What causes greenhouse gasses to absorb heat when gasses like oxygen do not?
Scilla [17]

Answer:

Hope the below helps!

Explanation:

Greenhouse gases (such as methane, carbon dioxide etc) have lots of vibrating particles. These molecules eventually release radiation, which travels up Earth's atmosphere (because warm air rises), is trapped and adds to the greenhouse gas effect.

Oxygen and nitrogen don't interfere with infrared waves in the atmosphere. That's because molecules are picky about the range of wavelengths that they interact with.

I have attached a diagram that shows the greenhouse effect. It might help to visualise this.

Which of the following options lists the stages in cellular respiration in the correct order? glycolysis, the citric acid cycle,
marishachu [46]

Answer:

The correct answer is  glycolysis, the citric acid cycle, and oxidative phosphorylation

Explanation:

Aerobic respiration contains three major processes that are glycolysis, the citric acid cycle, and oxidative phosphorylation.  

In glycolysis, partial oxidation of one mole of glucose gives two moles of pyruvate and 2 NADH and 2 ATP. Then this pyruvate is converted into acetyl-CoA in the mitochondrial matrix(in eukaryotes) and acts as a fuel for the Krebs cycle.

In the Krebs cycle, acetyl CoA gives rise to 4 CO₂, 2 ATP, 6 NADH, and 2 FADH₂. So from glycolysis and Krebs cycle, only 4 ATP is produced and most of the energy remains in the form of NADH and FADH₂.

So in oxidative phosphorylation electrons are released from these molecules into machinery of oxidative phosphorylation to synthesize ATP.

Use the drop-down menus to complete the statements. Anthers release pollen, which lands on the of another flower of the same spe
Tema [17]

Answer:

See the answer below

Explanation:

Anthers release pollen, which lands on the stigma of another flower of the same species. The pollen grain produces a pollen tube that grows down the style, to the ovary, and into the ovule. The sperm cell fertilizes the egg cell. The ovule develops into the seed, and the ovary becomes the fruit.

<em>During fertilization in plants, the anther which carries pollen releases pollen grains. Once the pollen lands on the stigma of a flower of the same species, it germinates. The pollen grain produces a pollen tube that grows through the style of the stigma down to the ovary and into the ovule. One of the sperm cells fuses with the egg cell of the ovule to form the zygote while the other sperm cell fuses with the polar nuclei to form the endosperm in a process known as double fertilization. After fertilization, the fertilized ovule becomes the seed and the ovary becomes the fruit. </em>

Why is this considered a nonscientific question?<br> "What color is a great horned owl?"
madam [21]

Answer:

The question "What color is a great horned owl?" does not require the scientific method to be used for getting an answer hence, it is not a scientific question. This question does not require any hypothesis or any other method. It can easily be answered by just looking at the horned owl.

A scientific question has to be a question from which a hypothesis can be made. The hypothesis can be tested through experiments and observations. Results and conclusions from the experiments would result in answering that question.

What is turgor pressure, what causes it, and what does it do for a plant?
ANEK [815]

Turner pressure is simply the force within the plant cell that pushes the cell membrane or plasma membrane against the cell wall.

It is caused by the Osmotic flow of water through the semi permeable membrane.

It helps the plant cells to remain turgid and stand tall so as to prevent it from wilting
