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.

Answers

Answer:

Red dwarfs are low-mass main-sequence stars. Yellow dwarfs are main-sequence (dwarf) stars with masses comparable to that of the Sun.

Sun is younger then proxima centauri as it is a red dwarf star whereas sun is a yellow dwarf. We now this as stars need hydrogen to burn and the older they get they get more red.

Describe a DNA mutation and how it can affect an offspring.

Answers

A DNA mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people. Mutations range in size; they can affect anywhere from a single DNA building block (base pair) to a large segment of a chromosome that includes multiple genes. DNA mutations can affect an offspring can result in abnormal protein products. Mutations can also introduce new alleles into a population of organisms and increase the population's genetic variation.
Since all cells in our body contain DNA, there are lots of places for mutations to occur; however, some mutations cannot be passed on to offspring and do not matter for evolution. Somatic mutations occur in non-reproductive cells and won't be passed onto offspring. For example, the golden color on half of this Red Delicious apple was caused by a somatic mutation. Its seeds will not carry the mutation.
The only mutations that matter to large-scale evolution are those that can be passed on to offspring. These occur in reproductive cells like eggs and sperm and are called germ line mutations.

I would say, no it gets colder because you become exposed to space where heat isn’t trapped in

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.

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.

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.

Answers

It is c I believe cause the human cells can’t make their own food like plants do when they photosynthesis

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.

(image below) 5/5 What is the subject of this sentence: Los estudiantes estudian mucho Why were joint-stock companies created? Assignment Summary For this assignment, you will construct a scientific model of the water cycle to show how water is recycled through an ecosystem. Once you have drawn your model on a poster board, you will write one to two paragraphs explaining how water is transferred within and between organisms and the environment. Background Information Water is a very important compound. Organisms need water to carry out life-maintaining processes such as growth and development. Without water, living things will not survive. Water continually flows among the atmosphere, land, water, and living organisms. This process, called the water cycle, allows water to be recycled as it moves through Earths spheres. Materials Assignment Instructions Step 1: For this project, you are expected to submit the following: 1. Your model of the water cycle 2. One to two typewritten paragraphs describing the water cycle Step 2: Prepare for the project. a) Read through the guide before you begin so you know the expectations of this project. Pay particular attention to the instructions you need to follow to create a model on your poster board. b) If anything is not clear to you, be sure to ask your teacher. Step 3: Gather materials for the model. a) Start with a blank poster board. Be sure to put your name on it. b) You may either draw the parts of the water cycle or print images to construct a model on your poster board. Gather any drawing tools that you will need, or print any images you want to use. Step 4: Create a model of the water cycle. a) Your model should include bodies of water such as lakes and oceans, organisms, air, and land. b) Draw arrows indicating how water moves within an ecosystem and between organisms and their environment. Be sure to include the Sun and gravity in your model. c) Include short phrases on your poster that summarize what occurs at each stage of the water cycle Step 5: Write a paragraph describing the water cycle. a) Type one to two paragraphs describing the full water cycle. Be sure to use full sentences and proper grammar.
