Let's think about this question and ask our selves what is life?
Think about a non-living thing, like a bike.

Does this bike have kids? Does it need to eat or sleep? What is it made up of? What does it need to survive? Does it need to be able to sense the environment around itself?

You're probably saying, no the bike doesn't do a lot of these things.

Humans, animals, and pretty much all living things need to perpetuate their genes by means of reproduction, whether it is asexual or sexual.
We need to animals need to eat and sleep, but you can just categorize this as a metabolic process. Plants need Nitrogen and CO2 and sunlight, to undergo metabolic processes and make glucose (another metabolic process). We also must be able to maintain an equilibrium while conducting metabolism (homeostasis).
We need to be able to sense the environment around ourselves to survive.
If you look at simple organisms, they are often able to detect different chemicals and know to be attracted or stay away from certain substances.

All living things are made up of cells.

A new strain of rice was developed to be resistant to popular weed killers. What could be a negative outcome from the production

asambeis [7]

B. Because of Farm laws that require no seeds to be kept from a harvest, or you are not allowed to have plants of a different genetic make or made by a different company in your field if you didn't buy it, you could have wind carry seeds into opposing fields, and if inspected, you would potentially have to pay a fine for having unauthorized varieties growing in your field. And trying to remove it would be a pain, because you would either have to find a killer that your plants are resistant to, or to find these individually and pluck them, or to spray a killer that would kill all of your plants, but none of these resistant varieties

If all green plants in the world were distroyed which atmospheric gas will increase

Mila [183]

Trees are a crucial part of the carbon cycle, a global process in which carbon dioxide constantly circulates through the atmosphere into organism and back again. Carbon is the second most valuable element to life, you know, after water. Anyway, trees take carbon from the atmosphere through photosynthesis in order to make energy. This carbon is then either transferred into oxygen and released into the air by respiration or is stored inside the trees until they decompose into the soil. Therefore, the absence of trees would result in significantly HIGHER amounts of carbon dioxide in the air and LOWER amounts of oxygen! The filthy air would also be full of airborne particles andpollutants like carbon monoxide, sulfur dioxide and nitrogen dioxide and its temperature may increase by up to 12 F.

Describe the relationship between the Sun and Climate Zones.

GalinKa [24]

The main driver of a climate zone is the amount and directness of sunlight that reaches the Earth's surface. In the tropical regions, there is a fairly constant amount of sunlight throughout the year. The maximum sun angle is also higher above the horizon.

Given a template strand of 3' ATGCTTGGACA 5' and partially made complementary strand containing only 5' TAC 3', what would be th

sineoko [7]

Answer: 5'-TACGAACC-3'

The enzyme DNA polymerase will form hydrogen bonds with the nucleotides of the template DNA and add new nucleotides, adenine will bond with thymine and guanine will bond with cytosine, forming the complementary strand.

3' ATGCTTGGACA 5 is the DNA template
5' TACGAACC .......3' is the complementary strand
you just need to join the right nucleotides. If there is no T, the DNA polymerase has nothing appropriate to connect to the A, so it stops there
