Proxima Centauri and the Sun are both main sequence stars, but Proxima Centauri is a red dwarf and the Sun is a yellow dwarf. Based on the information you charted, compare the characteristics of red dwarf stars and yellow dwarf stars.
Answer:
Red dwarfs are low-mass main-sequence stars. Yellow dwarfs are main-sequence (dwarf) stars with masses comparable to that of the Sun.
In an experiment, equal amounts of heated water and soil were left to cool down. The initial and final temperatures of each were recorded. A partial record of the temperature is shown.
Experimental Record
Substance Initial Temperature Final Temperature
Water 27 °C 24 °C
Soil 27 °C ?
Which statement about the final temperature of soil is correct?
It will be less than 24 °C as soil loses heat relatively faster than water.
It will be less than 24 °C as water loses heat relatively faster than soil.
It will be more than 24 °C as it takes relatively longer to change soil temperature than water temperature.
It will be more than 24 °C as it takes relatively longer to change water temperature than soil temperature.
Answer:
I think it will be less than 24 °C as water loses heat

What are two phases of a waxing moon, and how do they appear?
Answer:
The waxing of the moon can be noticed when the moon appears larger each night. A waxing moon has two phases, namely a waxing crescent and a waxing gibbous. During a waxing crescent, a thin crescent in the west part of the moon is visible. This indicates that the moon travels east in the sky. On the contrary, a waxing gibbous occur when more than half of the moon is visible. This indicates that the moon is almost halfway through its cycle.
Explanation:
Answer:
waxing gibbous waxing crescent

PLSSSSSSSSSS Which best explains why a person can tell the difference between a whisper and a yell?
Sound waves turn into chemical signals that indicate certain sounds.
Different vibrations in the ear cause the brain to interpret different sounds.
The fluid in the cochlea picks up electrical signals for the intensity of sound.
The eyes see what is making the noise and help the brain process the sound.
Answer:
The difference is the louder the sound the bigger the waves and your ears collect the sound waves and brings it to you brain

how are plant cells and human cells different?
a. human cells need food, but plant cells do not.
b. human cells need energy, but plant cells do not.
c. plant cells make their own food, but human cells do not.
d. plant cells make their own energy, but human cells do not.
Answer:
C- Plant cells make their own food, but human cells do not.
Explanation:
Animal cells must take food in from some other source. Plants, on the other hand, have the ability to make their own food through a process called photosynthesis. In essence, the plant cell uses the energy in sunlight to combine carbon dioxide and water to make molecules of glucose and to release oxygen.
D is wrong because the human body uses three types of molecules to yield the necessary energy to drive ATP synthesis: fats, proteins, and carbohydrates. Mitochondria are the main site for ATP synthesis in mammals, although some ATP is also synthesized in the cytoplasm.
A is wrong because plant cells obtain energy through a process called photosynthesis. Secondly, that energy is used to break down carbon dioxide and form glucose, the main energy molecule in plants. Plants, algae and some bacteria use photosynthesis to create energy used for growth, maintenance and reproduction.B is wrong because food provides building materials for your body. Your body needs building materials so it can grow and repair itself. Specifically, it needs these materials to produce more cells and its components. Food contains substances that help control body processes.A part of the periodic table is shown.

Read the following sentence:
"When you look at a basketball, what are you seeing?"
Why might the author have started the passage with this question?
a
to give the reader an object to visualize before examining the role of light
b
because the main idea of the passage is about basketball
c
because the author wants to use the example of basketball to explain electromagnetic radiation
d
to show how important the color orange is to electromagnetic waves
Answer:
Explanation: B because its talking about basketball
Answer:
I'm pretty sure A would be the answer
We can think of electromagnetic waves as a kind of ongoing message being sent out by the universe. Humans are able to naturally access only a portion of this message.
What information from the passage best supports this statement?
a
The waves emitted by our physical world make it possible for us to communicate over vast distances.
b
The human eye is only sensitive to a portion of the electromagnetic spectrum.
c
Without light, we wouldn't be able to process the visible world.
d
Mankind has invented tools to harness the information contained within electromagnetic radiation.

What are 3 reasons deforestation is an issue for animals?
Answer:
- Animals live in the trees
- Animals eat off of tree
-Animals breed in trees

Answer:
1. They have less territory
2. With less space, populations decline.

Answer:
A familiar example of homeostatic regulation in a mechanical system is the action of a thermostat, a machine that regulates room temperature.
Explanation:
Answer:
Humans' internal body temperature is a great example of homeostasis. When someone is healthy, their body maintains a temperature close to 98.6 degrees Fahrenheit (37 degrees Celsius). Being warm-blooded creatures, humans can increase or decrease temperature internally to keep it at a desirable level.

write a paragraph explain the relationship between a quasar and a black hole. using your own words, explain why this relationship might be of interest to astronomers.
Answer:
hey, this might not be much help but quasars are just galaxies while a black hole is just an invisable space that sucks all light and has VERY strong gravity. Astronomers will find this interesting because... omg am so sorry this is all I got :c I hope u pass this semester. Good luck dude
Explanation:
HELPPPPPPP!! To maintain homeostasis, the human body has many systems that remove wastes from the body. Which correctly explains how two organ systems interact to eliminate wastes?
A.
The muscular system helps the bladder to release urine from the excretory system to maintain homeostasis.
B.
The muscular system helps push carbon dioxide wastes from the respiratory system to maintain homeostasis.
C.
The muscular system helps squeeze solid wastes from the digestive system to maintain homeostasis.
