Whoever awnsers gets Brainliest!!! What causes a star to shine brightly?
the color that is produced
the energy that is released
the amount of gravity that is present
the types of elements that are present
Answer:
the energy that is released
Explanation:
heat gives off light, and the heat comes from the reactions in the star that produce the energy
Answer:
The energy that is released.
Explanation:
The source of most stars' energy is nuclear reactions going on deep inside the stars. In most stars, like our sun, hydrogen is being converted into helium which makes the stars shine brightly.

What is the difference between fragmentation and budding?
How are the genes split up in sexual reproduction?
Answer: hope this helps!!
Explanation:
How is fission different from budding?
1) Binary fission: Single parent cell doubles its DNA, then divides into two cells. Usually occurs in bacteria. 2) Budding: Small growth on surface of parent breaks off, resulting in the formation of two individuals. Occurs in yeast and some animals (like the hydra below).

Some individuals of a particular species of sea bird underwent a genetic mutation that resulted in larger beaks. The larger size of beaks helped
these birds to break open dams and other mollusks for food. It also helped them defend themselves against predators. After many generations,
almost all of the birds in the population had big beaks. For which two reasons did this phenomenon occur?
A. natural selection
B. mechanical Isolation
C. prezygotic barriers to reproduction
D. high genetic variation in the species
Answer:
The answers would be A and D I think
Explanation:
Life: Scientists have found signatures of life in
rocks from 3.5 billion years ago. That means life
existed in a world with very low oxygen! What
is the evidence?
Answer:The evidence to this is because oxygen, is produced by bacteria at that time! If they do That why would they need to use any oxygen? If i didn't get the answer you were asking then well sorry :/
How are plant and animal cells different in size and shape
Answer:
plant cells are rectangular while animal cells are spherical
Explanation:
plant cells are mostly rectangular due to the cell walls morphing them into that shape while animal cells are more sphere like in order to save space

CCC Predict: Suppose you randomly picked out two members of the
same phylum and two members of the same genus. Which pair of
organisms would you expect to have more characteristics in
common? Explain your answer.
ANSWER:
Answer:
genus
Explanation:
the closer something is to species, the more they have in common. and genus is closer to species than phylum
Answer: genus
Explanation: the more close something is to something else the better so in my opinion its genus
SUMMATIVE REFLECTION: What are living things made of? Set a timer for five minutes. Write small. Fill the space below with everything that you remember about biochemistry.
Answer:
All living organisms are made up of one or more cells, which are considered the fundamental units of life. Even unicellular organisms are complex! Inside each cell, atoms make up molecules, which make up cell organelles and structures. In multicellular organisms, similar cells form tissues.

If a woman has had a intercourse, and she missed a menstrual period by more than 14 days, she probably is pregnant. True or False
Answer:
true
Explanation:
Answer:
True.
Explanation:
Periods can come late, but even so, if the woman is an adult and has mostly predicable and a regular schedule that can be tracked, then the period could be late for at least 7-9 days MAX. 14 days would be pushing it.
Some differentiated cells become senescent almost immediately, leaving the cell cycle and undergoing terminal differentiation. Other cells have a high need to proliferate in order to grow and repair the organ or tissue, so they do not enter senescence for a long period of time. Which cell type would be most likely to put off senescence and terminal differentiation so it could continue to replicate in order to grow and repair?
brain cells
lung cells
skin cells
heart cells
Answer:
skin cells.
Explanation:
for connexus friends
The cell that will most likely put off senescence and terminal differentiation so it could continue to replicate in order to grow and repair would be skin cells.
The skin is a tissue whose cells are constantly dividing to replace old, damaged, or worn-out cells.
Damaged, and worn-out cells are frequent on skin tissues because they directly interact with the environment, exposing them to mechanical, chemical, and other forms of damages.
Thus, the skin cells cannot afford to go into senescence or terminal differentiation due to the fact that they need to constantly divide and replace damaged ones.

Which statement is an example of a scientific theory?
A.
All living organisms are composed of one or more cells, which came from pre-existing cells.
B.
Hummingbirds do not like the color white because they visit other colored flowers more often.
C.
The Earth is the third planet from the Sun and has one moon, which orbits the Earth.
D.
The amount that caffeine affects a person's heart rate differs based on the person's age.
Answer:
d
Explanation:
a theory is similar to a hypothesis except has backed up evidence already
Answer:
A
Explanation:
A is always true while the others are sometimes true, C is true in our galaxy, but not others. B is opinionated, different humming birds may like different colors. D is not considering other variables that could effect that situation, such as weight, height, blood pressure, etc. Therefore, A is correct.

What are the differences encountered in the photosynthetic-respiratory pathway of the carbon cycle, as it exists on land and in the ocean?
In a marine environment, the role of plants is performed by _______(phytoplankton, zooplankton, microorganisms) and an additional flux of carbon into the oceans is through _______(aeration, diffusion, deposition).
Answer:
phytoplankton; diffusion
Explanation:
"Phytoplankton" takes the role of the plant in the marine environment because it consists of tiny plants that contain chlorophyll–just like the terrestrial plants. This provides food to many aquatic animals in the ocean.
When it comes to carbon cycle, carbon dioxide from the atmosphere is being diffused into the ocean by dissolving it. The carbon in the ocean turns into an organic matter through the process of photosynthesis. The ocean is said to have more carbon compared to the atmosphere because many marine animals use it for survival.

Why do you think the top carnivores, that are tertiary consumers, cause there to be an increase thenumber of different types of species found in the ecosystems they live in?
Answer:
Bio Diversity
Explanation:
Top carnivores don't eat everything in the ecosystem which would let the uneaten species able to evolve and become new species (I don't know I'm just guessing sorry if this is wrong)

What are TWO ways that species are becoming endangered due to human behaviors?
Why is it dangerous to have too much carbon dioxide in the atmosphere
Answer:
too much CO2 is toxic for humans to inhale. we rely on plants to absorb CO2 and produce O2. If they was a sudden extinction of all plants on earth, this would lead to a rise of CO2 which would reduce O2 air quality. (not good at all)
