The moon seems to change shape form day to day in a cycle that last about a month as it goes through
A)Revolutions B)Phases C)Rotations D)Eclipses
Answer:
B. phases
Explanation:
The changing shape of the moon in the sky is called phases.
The moon seems to change shape from day to day in a cycle that lasts about a month as it goes through Phases.
How does the Moon's shape seem to alter?
The Moon seems to change shape because we notice distinct amounts of the lit portion as the Moon orbits Earth.
When the Moon is between Earth and the Sun, the lit flank is obscured from us.
As it moves around Earth, the lit flank comes into view. Then it commences and vanishes again.
Thus, The moon seems to change shape from day to day in a cycle that lasts about a month as it goes through Phases.

Heredity is the passage of genetic instructions from parent to offspring. The genetic instructions are found in within the DNA, which is contained in inside the nucleus of the cells. The genetic information is passed to the next by sexual reproduction. The information controls the traits that passed down. These include characteristics like eye color and characteristics like blood type. These traits are directly passed down and are not affected by the surrounding the organism.
Answer:
What is your question
Explanation:
The passage of genetic instructions from parent to offspring, known as heredity, involves the transmission of genetic information contained within the DNA.
The DNA is primarily located within the nucleus of cells. During sexual reproduction, genetic material from both parents combines to form a unique set of instructions for the offspring.
This genetic information controls the traits that are inherited, including observable characteristics like eye color and blood type. These traits are directly inherited and are not influenced by the surrounding environment of the organism.
While genetic information provides a blueprint for traits, the expression of those traits can be influenced by environmental factors, such as nutrition, exposure to toxins, or lifestyle choices.

Could an animal adapted to live in an ecosystem at the bottom of the Rocky Mountains survive in an ecosystem at the top of the Rocky Mountains? Explain your answer.
Answer:
No, the environment would be completely different. At the bottom of the mountains there would be certain things that at the top you would not find and vice versa. The oxygen levels would also be different. The most important point is that an animal doesn't adapt easily. For example we humans, we live on the ground if we decided to live on Mt. Everest the lifestyle would be so hard to adapt to because we aren't used to it, like oxygen levels, food sources, temperature, etc. Same thing with this animal.

The fluid-mosaic model of the cell membrane suggests that the membrane is primarily composed of proteins and lipids. Which of the following is a function of proteins in the cell membrane
A to read messenger RNA to assemble amino acids
B. to provide a hydrophilic head so that water can enter the cell
c. to package and sort molecules to be sent in vesicles
D to allow substances to cross the plasma membrane via active transport
Answer:
B
Explanation:
Protein as amino acids
The fluid Mosiac Model is a theory that explains the structure of the functional cell membranes. The model is characterized by the lipid bilayer, in which protein molecules are embedded.
The correct answer is:
Option B. to provide a hydrophilic head so that water can enter the cell
The functions of protein in the plasma membrane are:
1. The lipid bilayer is amphiphilic, such that they have a hydrophobic and a hydrophilic end.
2. Membrane proteins are involved in the transportation of ions, molecules, or other substances across the membrane.
3. The membrane protein is selectively permeable such that, the aquaporins are the family of proteins, which is involved in the flow of water inside and outside the cell.
Thus, the correct answer is Option B.

a. interphase
b. telophase
c. cytokinesis
d. mitosis
Answer:
a. interphase
Explanation:
The gap 1, gap 2, and synthesis stages of the cell cycle make up the interphase. Thus, the correct option is A.
What is the cell cycle?The Cell cycle may be defined as the entire sequence of events happening from the end of one nuclear division to the beginning of the next. The cell cycle can be divided into two phases. They are:
The Interphase.The M-phase (division phase).Interphase comprises the G1 phase, S-phase, and G2 phase. The G1 phase is the resting phase. DNA synthesis does not take place. It is involved in the synthesis of RNA and protein. S-phase deals with the synthesis of DNA and histone proteins.
While the G2 phase is the continuous synthesis of RNA and proteins. After this phase, a cell enters the M phase.
Therefore, the gap 1, gap 2, and synthesis stages of the cell cycle make up the interphase. Thus, the correct option is A.

Which of the following contribute to the elevated level of carbon in the atmosphere? a. greenhouse emissions b. deforestation c. humans d. all of the above
Answer:
d. all of the above
Explanation:
All of the given choices contribute to the elevated level of carbon in the atmosphere.
This is one of the leading cause of climate change.
Greenhouse emissions from the surface is a huge problem which originates from increasing the release of these gases into the atmosphere. Carbon dioxide is one of the greenhouse gases, and it is the main component of the emissions. Deforestation involves the removal of trees from the earth surface. Trees naturally removes carbon from the environment. They use the carbon to manufacture their own food. Human activities such as industrial processes, burning of firewood for cooking, etc. all contributes significant amount of carbon into the atmosphere.What type of selection is seen in rock pocket mice

ok I have like this campaign thing for science so i have to try and get people to vote for the mitochondria so on a slide i have to include the structure and the function of the mitochondria and be sure to relate them it also says it is very important to make the connection with the voters about why the mitochondria is the most important so include why the mitochondria is crucial for survival of your organism so if anyone can help that would be amazing
Answer:
The mitochondria is the most important organelle because it is where energy is produced through cellular respiration. It serves as an energy source for eating, breathing, moving, and thinking: all basic units of life. If there were no mitochondria many essential functions of the cell could not happen.

We are pretending that I am testing to see if Vitamin C cures ashy skin. You must write out EVERY step of the study that I must do, especially the actual experiment part. You must also list the "controlled variables", the "independent variable", and the "dependent variable
Answer: Independent variable is the Vitamin C and the ashy skin is the dependent variable.
Explanation:
We can change or manipulate the independent variable of the reaction and such change can be observed on the dependent variable. The dependent variable yields the results of the experiment and changes in the dependent variable must be observed attentively to frame the results.
Here, vitamin C is the independent variable whose affect has to be observed on the ashy skin which is the dependent variable of the experiment. Steps of the experiment:
1. We can apply Vitamin C in a form of solution on the ashy skin.
2. Observe the changes on the skin directly and apply for 2-3 times in a day.
3. Observe the changes on the skin after a week.
