why do we see different phases of the Moon
During the lunar month, the Moon goes through all its phases. You can see the phases drawn in the image below. Just like the Earth, half of the Moon is lit by the Sun while the other half is in darkness. The phases we see result from the angle the Moon makes with the Sun as viewed from Earth.
hope this helps :)
Moon is the natural satellite of the Earth, which rotates and revolves around the Earth. The moon reflects the sunlight, which makes it visible to the Earth.
The different phases of the moon are seen due to the revolution of the moon around the earth. It can be explained as:
1. The moon does not have its own light, such that it reflects the sun's light.
2. When the moon revolves around the Earth, it can reflect some portion of the light. The different portions of the illuminated moon result in different phases.
3. The phases of the moon are crescent, gibbous, full moon, waning, and waxing moon.
Thus, the moon when orbits around the Earth and gets reflected at some portions will give rise to different phases.

An example of natural selection is the red color of a male cardinal. The females of the species choose mates based on the vibrant colors of the males’ feathers. If females begin using different criteria than feather color when they choose mates, what would most likely happen to the tails of peacocks over time?
If female’s species would chose their mates using different criteria other than feather, it may lead to decrease in variation in tail feather color because the only reason for the variation was selection pressure.
Explanation:
The opposite gender for mating are chosen based on specific criteria like color of feathers, eye color etc..The selection of opposite gender is the natural selection considering the red color of the male cardinal. This red color male cardinal which depends only on the sexual selection pressure will now reduce. As this was now neutralized it may lead to decreased variation.
Answer:
Decreased variation in the shades of red because no form of the trait is advantageous.
Explanation:
Natural selection may be defined as the differential reproduction and survival of the individual due to their differences in the phenotype. Natural selection acts as the main driving force for evolution.
The male cardinal red color gets change or may show variation as it is no longer used by them to attract the females. The red shade variation get decreases and may get changed over time. The red color trait is non advantageous and get extinct with time.

Does Earth’s gravitational force field act on objects that aren’t touching Earth’s surface?
yes because when things are flying, they have to be propelled. Thats how gravitty works lol.
If ur talking about stuff in space, then yes to that too. They moon revolves because of gravity and inertia
Yes, Earth's gravitational force field acts on objects that aren't touching Earth's surface. The gravitational force between two objects, like Earth and any other object, depends on their masses and the distance between them.
What is the gravitational force?According to Newton's law of gravitation, the gravitational force between two objects is proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
The Earth's gravitational force is due to the planet's mass and size. All objects near the planet, including those above its surface, experience a gravitational pull because of the Earth's gravitational force.
Gravitational force is the force of attraction which is present between any two bodies and it is responsible for holding the objects in place.

what is the second step of protein synthesis?
The second step of protein synthesis is translation
Final answer:
The second step of protein synthesis is translation, where mRNA is read by a ribosome in the cytoplasm and tRNA molecules bring corresponding amino acids to form a polypeptide chain. The process consists of initiation, elongation, and termination stages.
Explanation:
The second step of protein synthesis is called translation. During translation, mRNA that has been transcribed from DNA is read by a ribosome to assemble a polypeptide chain. The ribosome facilitates the binding of transfer RNA (tRNA) molecules that have attached amino acids, corresponding to the codons on the mRNA. The tRNA transfers amino acids to the growing polypeptide chain in the correct sequence, contributing to the formation of a functional protein.
Steps of Translation:
Initiation: A ribosome binds to mRNA with the help of initiation factors and an initiator tRNA.Elongation: tRNA molecules bring amino acids to the ribosome, which adds them to the growing polypeptide chain.Termination: The process ends when a stop codon on the mRNA is reached, releasing the newly formed protein.Translation occurs in the cytoplasm of the cell where ribosomes are located and play a key role in assembling proteins.

Which two words describe an organism that eats organisms as food
Carnivore, consumer
The two words that describe organisms that eat other organisms as food are 'consumer' for those who rely on others for energy and 'decomposer' for those who break down waste materials and dead organisms.
Explanation:The two words that describe an organism that eats other organisms as food are consumer and decomposer. Consumers are organisms that cannot produce their own food and rely on other organisms for energy. They include animals, some bacteria, and a few plants such as the pitcher plant. Consumers can be further divided into herbivores (like rabbits that eat plants), carnivores (like lions that eat other animals), omnivores (like humans that eat both plants and animals), and scavengers (like hyenas that eat dead animals). On the other hand, decomposers play a role in breaking down dead organisms and waste materials, thereby releasing nutrients back into the ecosystem. Examples of decomposers include fungi and certain bacteria.
