Question: How does a region’s latitude impact its climate? What role does the sun play on an area’s climate?

Answers

Answer:

Places with latitudes closer to the Equator have hotter climates. Places with latitudes closer to the Poles have colder climates. This happens because the Sun's rays hit them more or less directly.

The Sun powers life on Earth; it helps keep the planet warm enough for us to survive.

animals.

Inherited traits are passed down to offspring from parents through their genes. Inherited traits are things that are genetic and with an animal from birth. Both of their parents pass these traits to them, and they become a mix of their parents. Hair color, eye color, fur patterns are all examples of inherited traits.

Opsins are proteins that are found in the light-sensing cells in the human eye. Different opsin proteins are sensitive to different colors of light. The instructions for creating the type of opsin sensitive to red light are found on a gene known as OPN1LW, which is on the X chromosome. A genetic mutation in the OPN1LW gene can lead to a form of color blindness that affects a person's ability to detect red light. However, women have two copies of the X chromosome, and they have normal color vision if only one copy contains the mutation. Why do women who carry one copy of the mutated gene still have normal color vision?

Answers

Answer:

Women who carry one copy of the mutated gene still have normal color vision because they have another copy, which is not mutated, in the other X chromosome that will be the dominant one. As a result, the women are carriers of the mutated gene but not color blind.

Explanation:

Colorblindness is a sex-linked mutation. A woman has two X chromosomes, while a man has one X chromosome and one Y chromosome. The mutated gene that causes color blindness is on the X chromosome, and it is OPN1LW. So if a woman has one mutated OPN1LW in one of her two X chromosomes, the OPN1LW gene in the other X chromosome will be the dominant one stopping the woman from being colorblind.

In the case of men, as they only have one X chromosome, if there is a mutation on the OPN1LW in the X chromosome, the men will be colorblind because there is no extra copy of the gene, as it is in women.

Answer:

2. In the natural environment, plants produce their own food to survive. As with photosynthesis, plants get oxygen from the air through the stomata. Respiration takes place in the mitochondria of the cell in the presence of oxygen, which is called "aerobic respiration".

3.  Both cellular respiration and fermentation are process that break down food and convert the chemical energy stored in the food to ATP molecules. Both these processes begin with glycolysis and convert glucose to pyruvate. ... Fermentation only uses the latter.

4. Energy is usually absorbed during photosynthesis.

Photosynthesis is the process whereby green plants manufacture their food in the presence of sunlight(energy source), water and carbon dioxide:

       6CO₂    +     6H₂O          →           C₆H₁₂O₆          +       6O₂

                                                ↑

                                         Sunlight

Sunlight supplies solar energy that is used to converted the chemical species into glucose that stores chemical energy.

 Respiration is the reverse of photosynthesis. In this reaction, oxygen gas combines with glucose to produce energy with water and carbon dioxide as by products. The energy stored in photosynthesis is released during respiration.

Or, if a different topic comes to mind and meets the criteria, you may use it. Once you have chosen a topic, do a quick online search to see if there is enough information available about it. If the topic is so broad that you think you cannot do it justice in a single paper, try narrowing it. One way to narrow a topic is to ask yourself questions to which you would like to learn the answers. For example, suppose the broad topic is this: Alternative medicines - helpful, unhelpful, or harmful? You might write down questions that make you curious, for example: 1) What types of alternatives medicines exist? 2) What ailments are alternative medicines claimed to be effective for? 3) What studies have been done about alternative medicines? 4) What results have doctors and patients reported? Such questions can guide your research. 1) Write your topic. 2) Write two or more questions that you would like answered about your topic. 3) If you wish to narrow your topic, write the narrow version here. 4) Phrase your topic as a research question that your project will answer.
