Compared to the Sun, the star Betelgeuse is
A. Less luminous and warmer
B. Less luminous and cooler
C. More luminous and warmer
D. More luminous and cooler
Red supergiant star Betelgeuse is around 764 times as massive as the Sun. To put that into perspective, the diameter of Mars' orbit around the Sun is 328 times that of the Sun. Thus, option A is correct.
What is the comparison of Sun and star Betelgeuse?Betelgeuse is 640 light years away from the sun. Given that the star is only 10 million years old, it will die young like earlier supergiants.
The sun, in contrast, is only approximately halfway through its life and is nearly 4.6 billion years old.
Betelgeuse is one of the gleaming stars in the night sky and can be seen clearly on the right shoulder of the constellation Orion.
Betelgeuse is a red supergiant that is 1,400 times bigger than our Sun and thousands of times brighter.
Therefore, Compared to the Sun, the star Betelgeuse is Less luminous and warmer.

tertiary consumers.
B) They are caten by secondary consumers.
C) They contain the most biomass out of all of the
trophievels.
D) They are the largest trophic level.
E) This level of the food chain has the highest
amount of diversity.
They attract secondary consumers, this applies to the tertiary consumers of the ecosystem.
What do you mean by ecosystem?An ecosystem consists of all the organisms and the physical environment with which they interact. These biotic and abiotic components are interconnected through nutrient cycles and energy flows. Energy enters the system through photosynthesis and is incorporated into the plant tissue.
The term "ecosystem" was first used in 1935 in a publication by British environmentalist Arthur Tansley. The term was coined by Arthur Roy Clapham, who coined the word at Tansley's request.
The main ecosystem types are forest, desert, rainforest, grassland, tundra, savanna, and mountain ecosystems.

How does mutation increase chances for survival? Please help me.
Answer:
These mutations can increase an organism's chance for survival and usually occur over a course of many generations producing offspring (or babies) with the helpful mutation. ... This would allow you to mate and produce offspring because you would have survived for longer lifespans.

Buffers are substances that help resist shifts in pH by (From the close reading exercises)
A. releasing H+ to a solution when acids are added.
B. donating H+ to a solution when bases are added.
C. accepting H+ from a solution when acids are added.
D. both donating H+ and accepting H+.
Answer:
Buffers are substances that help resist shifts in pH by both donating H⁺ and accepting H⁺ (option D).
Explanation:
A buffer is a chemical substance capable of balancing the pH of a solution, when the balance is altered by the addition of an acid or a base. They are also called cushioning solution, and can be formed by an acid and its base conjugated, with a specific range of action.
The presence of a buffer in a solution has the ability to release hydrogen ions (H⁺) or accept them, helping to balance the pH, in the presence of a base or an acid, respectively. That is, a buffer can yield H⁺ to a solution when there are few or accept H⁺ when its content is high.
The other options are not correct because:
A. Buffers do not release H+ into a solution when acids are added, but accept them.
B and C. Giving up H+ to a solution when bases are added or accepting H+ from a solution when acids are added are effects that buffers can potentially do, which is described in the text above.

In the United States, alcoholic beverages that are sold in stores display a government warning stating that pregnant women should not drink alcoholic beverages. This is because
it prevents cleavage division from occurring, so a zygote cannot become a blastocyst.
if a woman drinks alcohol while she is pregnant, she may not be able to ovulate again after childbirth.
studies have proven that alcohol consumption causes long-lasting disorders in the fetus.
the science of chemistry has shown that alcohol is a reactive substance that may interfere with the mother’s food digestion.

Provide evidence to support the claim that viruses fall on the border between living and nonliving.
Answer:
Just like living organisms, viruses use genetic material such as DNA or RNA, but unlike living things, they cannot reproduce using mitosis, binary fission or meiosis. Instead, they simply insert the genetic material into a living cell and then replicate their genetic material along with the cell's in order to create more viruses.

Essay on atoms 70 words
Answer:
The atom, the basic building block of matter, consists of a core nucleus surrounded by negatively charged electrons. Inside the atom nucleus contains a mixture of positively charged protons, and electrically neutral neutrons. All atomic electrons bind to the nucleus through electromagnetic force. A ground of electrons bound together will form individual molecules. An atom with an equal number of protons and electrons will hold neutral. An ion has positive or negative charge, either through a lack of electrons or an electron excess. The number of protons determines the formation of chemical elements, while as the number of neutrons determines the element's isotope. Most of the atom's mass has a concentration compacted within its nucleus; however, protons and neutrons hold about the same mass. Electrons bound to atoms hold a percentage of stable energy levels, otherwise known as orbitals, which undergo transitory processes through absorbing or omitting photons with equal energy levels. Electrons determine an element's chemical properties, thus influencing an atom's magnetic properties.

b) How does the thermal energy of solid water change as it melts?
Answer:
Hi! So solid water would be ice, the particles in ice are very close together which makes it firm and makes it ice. When you put the ice in the microwave, (Microwave has heat so it would be thermal energy!) the particles in the ice mover a tiny bit away from each other which then makes it water. Then, if you boil the water, the particles that are in the water move far away from each other and it turns into steam!

Answer:

I hope it helps
Thank U
[tex]\red{Answer:-}[/tex]
✭The Hominini, or hominins, form a taxonomic tribe of the subfamily Homininae ("hominines"). Hominini includes the extant genera Homo (humans) and Pan (Chimpanzees and Bonobos), but excludes the genus Gorilla (gorillas).
✭The term was originally introduced by John Edward Gray (1824), long before any details on the speciation of Pan and Homo were known. Gray's tribe Hominini by definition includes both Pan and Homo. This definition is still adhered to in the proposal by Mann and Weiss (1996), which divides Hominini into three subtribes, Panina (containing Pan), Hominina ("homininans", containing Homo "humans"), and Australopithecina (containing several extinct "australopithecine" genera).
