Answer:
The embryonic period of gestation is the period after implantation, during which all of the major organs and structures within the growing mammal are formed.
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?
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.

List the order of vessels the blood travels after it leaves the heart to the point that it is returning to the heart.
Answer:
Blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs. Blood leaves the heart through the aortic valve, into the aorta and to the body. This pattern is repeated, causing blood to flow continuously to the heart, lungs and body.

We discovered that both carbon dioxide and methane have been increasing in earths atmosphere. What ideas do you have about why this might be happening? What could be causing earths atmosphere to change?
Answer:
Due to human activities.
Explanation:
This change in the concentration of carbondioxide and methane gas is happening due to human activities because human used fossil fuels which can be burn in the engines of vehicles that releases carbondioxide gas in the atmosphere. Humans are responsible for the change of atmosphere which leads to change in the climate all over the world. Methane gas is also released by human activities such as using methane for cooking food.
Which catastrophic event would most likely result in trees being knocked over and the
disappearance of most of the plants and animals along a narrow path in a forest
ecosystem?
Answer:
tornado
Explanation:
earthquakes dont cause for the disappearance of most of the plants and animals, flash floods are widespread, between volcanos and tornadoes, tornadoes fits the description better.
The catastrophic event that resulted in trees being knocked should be considered the tornado.
What is a tornado?It is the column that contains the small diameter with respect to the violence that rotated the air developed. It arises the thunderstorms at the time of spring and summer in the mid-latitude.
Also, the earthquake does not leads to the disappearance for mostly plants and animals.
hence,
The catastrophic event that resulted in trees being knocked should be considered the tornado.

When water molecules are attracted to one another, the arrangement is
Group of answer choices
an oxygen atom on one molecule to only the oxygen atom on another molecule.
a hydrogen atom on one molecule to either hydrogen or oxygen of another water molecule.
an oxygen atom on one molecule to only hydrogen on another molecule.
a hydrogen atom on one molecule to only a hydrogen on another molecule.
Answer:
An oxygen atom on one molecule to only hydrogen on another molecule.
Explanation:
Water molecules have a polar charge (the oxygen side is more negative than the hydrogen side) so the oxygen side will attract towards the hydrogen side.

9. Give an example of a trait and explain how a genetic trait is passed down from parent to offspring in
animals.
Answer:
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.

What role does cellular respiration play in the carbon cycle
Answer:
Hello, the cellular respiration is the process where organic sugar gets broken down to create and preform energy. It's very important because it releases the carbon dioxide from within our body and out into the atmosphere..
Scientists are concerned about a decrease in global biodiversity due to extinctions of organisms now and in the future. Scientists know about a mass extinction that wiped out the dinosaurs in a very short time. Describe a possible cause of this mass extinction and two consequences that may give scientists cause for alarm about the possibility of future mass extinctions.
Answer:
Mass extinctions happen because of climate change, asteroid impacts, massive volcanic eruptions or a combination of these causes. One famous mass extinction event is the one that lead to the extinction of dinosaurs, 65 million years ago.

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.
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O ↑ energy
Explanation:
