How is pillow lava evidence of
sea-floor spreading?

Answers

Answer 1
Answer: Pillow lava is evidence of sea-floor spreading because the lava comes up out of cracks at the mid-ocean ridge and becomes newly formed rock. The farther away you get from the mid-ocean ridge, the older the rock is.

3. List 2 similarities
and 2 differences between the carbon cycle on land
and the carbon cycle in water.

Answers

1 - carbon dioxide is mainly found in the lithosphere, and in the ocean ( generally in larger bodies of water)

2 - global warming + pollution + population increase + cutting down forests has all factored toward the growing amount of carbon dioxide in our atmosphere.

3 - carbon cycle on land moves faster than in water
on land the caarbon is czarried whereas in the water carbon is dissolved

plants and animals help both in water and land carry out the carbon cycle
both land and water have many carbon resources such are sediments and rocks.

You and your body maintain homeostasis by

Answers

The body maintains homeostasis by maintaining a relatively constant environment within the body. The organ systems help control the internal environment so that it remains relatively constant. Most cells of the body are surrounded by a small amount of fluid, and normal cell functions depend on the maintenance of the cells' fluid environment within a naroow range of conditions including temperature, volume, and chemical content. For example: the digestive, respiratory, circulatory and urinary systems function together so that each cell in the body receives adequate oxygen and nutrients and so that waste products do not accumulate to a toxic level.

30. How many DNA codes are used by life on Earth?

Answers

The DNA code contains 64 combinations that are named as codons. These codons are coding for the 20 amino acids, which the cell then puts together to form long amino acid chains, known as proteins.

What is DNA?

DNA stands for deoxyribonucleic acid. It may be defined as a molecule that is present inside cells that contains the genetic information responsible for the development and function of an organism. DNA molecules allow this information to be passed from one generation to the next.

There are 3.2 billion DNA codes that are used by life on Earth. Of the three billion genetic building blocks that make us living things, only a handful are uniquely ours. In fact, despite our differences on the outside, humans are 99.9% genetically similar to one another.

Our genetic manual holds the instructions for the proteins that make up and power our bodies. But less than 2 percent of our DNA actually codes for them. The rest 98.5 percent of DNA sequences is so-called “junk DNA” that scientists long thought useless.

Answer:

That's how much information is stored in the DNA inside every human cell: the entire human genome. If you sort through the three billion letters that make up the human genome, you find some surprising things. Only about 1% of the three billion letters directly codes for proteins.
