what is the importance of oxygen
Hello True Beauty fan!
Most living things need oxygen to survive. Oxygen helps organisms grow, reproduce, and turn food into energy. . Oxygen gives our cells the ability to break down food in order to get the energy we need to survive.
Oxygen is essential to have efficient cellular respiration; most organisms need oxygen for a single purpose: to release energy from food for use by cells.
A ______occurs when the Earth casts a shadow that partially or fully covers the Moon
O lunar eclipse
O summer solstice
O solar eclipse
Answer:
Lunar eclipse
Explanation:
During a lunar eclipse, the earth enters between the sun and the moon, thus preventing sunlight from reaching the moon. There are two types of lunar eclipses: A total lunar eclipse occurs when the moon and the sun are on opposite sides of the earth. When only part of the earth's shadow covers the moon, a partial lunar eclipse will occur. In some cases, it is called a blood moon, similar to the blood moon that occurs this month.
Do most mutations that are passed onto future generations come from the environment?
Answer:
If a trait is advantageous and helps the individual survive and reproduce, the genetic variation is more likely to be passed to the next generation (a process known as natural selection). ... In addition, the environment in which a population of organisms lives is integral to the selection of traits.
Explanation:
Answer:
No. They come from genetics and DNA structure.

Answer:
1. Kingdom Animalia
2. Yes
3. No
4. The taxonomic ranks get more specific as you go down the upside-down pyramid. As you go down the levels, the animals left are more similar but there is only one animal in the species category; the polar bear.
(Needs Two More Sentences)
1. Kingdom Animalia contains the greatest number of different organisms.
2. Yes, all organisms shown in the diagram that belong to the order also belong to the Phylum
3. No, all organisms shown that belong to the class Mammalia also below to the genus Ursus.
4. Ursus arctos—the brown or grizzly bear—is a species. It represents a separate genetic and physical group.
Diversity grows from species to kingdom. Animalia includes mammals, birds, reptiles, and more, including Ursus arctos. Multicellularity and heterotrophic feeding are common traits in the kingdom Animalia. From species (Ursus arctos) to kingdom (Animalia), organism diversity rises.

Help me past due Write down what you think will happen to the density of water if you add salt or sugar.
Answer:
If I add sugar or salt, the water's density will increase.
Explanation:
Density is the relation between mass and volume. We can represent it with the formula δ= m/v. Where δ stans for density, m for mass, v for volume.
If we add salt or sugar, we increase the mass, but the volume is the same. As a result, the density will increase.
We can use numbers to understand it better.
Suppose that before adding salt or sugar, the mass is 1 g and the volume is 1 l
δ= 1g/l1t
δ= 1 g/lt
Now, if we add sugar or salt, the mass increases. Suppose that we have 2g of mass and the volume is the same, 1l.
δ= 2g/1lt
δ= 2g/lt
We can see that the density increased when the mass increased.
The ultimate goal of sustainable development is to _______. a. limit the future use of resources b. meet current and future resource needs c. increase the current use of resources d. reduce resource use but increase supplies Please select the best answer from the choices provided A B C D
