Answer:
Prior to the buildup of oxygen, organisms were mainly anaerobic and used mechanisms where no oxygen was present or needed. Once the buildup of oxygen starting occurring, organisms were forced to either evolve to survive or they would die off due to the presence of oxygen. The organisms needed to evolve so that they could use and benefit from the abundance of oxygen. The presence of oxygen is a huge evolutionary milestone that kick started the evolution of many new species. Organisms began to metabolize and perform all of its functions with oxygen present.

At a depth of 100 meters, what color would a yellow object appear
to a person at that depth?
Answer:
green
Explanation:
Using the photosynthesis equation, predict how the rate of photosynthesis might change with variation in the following parameters (assuming that the plants is not receiving the maximum amount it can use):
a. The amount of light hitting a leaf
b. The availability of water
c. The amount of carbon dioxide in the atmosphere
d. The air temperature when water is limiting factor
Answer:
the answer is below
Explanation:
a) A plant process that changes sunlight into chemical energy. If there is less light the plant wont be able to function properly
b) Without enough water in the cells, the plants droop, so water helps a plant to stand. Water gives plants moisture to keep them alive.
c) If there is not enough CO2 the plant wont be able to photosynthesise as fastly as it usually does.
d) If the temperature is high and there is lack of water the plant is most likely to die. This is because it will be dehydrated.

Why does ice have the lowest density?
Answer:
Ice actually has a very different structure than liquid water, in that the molecules align themselves in a regular lattice rather than more randomly as in the liquid form. It happens that the lattice arrangement allows water molecules to be more spread out than in a liquid, and, thus, ice is less dense than water.
2. The allele for webbed hands (W) is dominant to normal hands (w). Complete a Punnett square
to predict the offspring should a heterozygous male cross with a heterozygous female.
a) Determine the genotype of each parent:
(parent one)
(parent two)
b) Complete the punnett square
c) Complete the ratios of the genetic cross:
d) What is the percentage that the offspring will have webbed hands?
e) What is the percentage that the offspring will have normal hands?
When a heterozygous male (Ww) crosses with a heterozygous female (Ww), the resulting offsprings possess genotypes WW, Ww, Ww, and ww.
What do you mean by Genotype?Genotypes may be defined as the ultimate combinations of the alleles of those genes which are selected for studies.
The genotypes of both parents are heterozygous i.e. Ww. The ratio of the complete genetic cross is 3:1.The percentage that the offspring will have webbed hands is 75%. (WW, Ww, Ww)The percentage that the offspring will have normal hands is 25% (ww).The Punnett square is attached below:

How is static electricity created?
a. Two objects that are both positively charged repel each other and release
electric energy.
b. Two objects that are both negatively charged become attracted and create a
spark.
c.
Two highly conductive materials are placed within close proximity of one
another.
d. Friction between two objects causes a transfer of electrons from one object to
the other.
.
Answer:
d
Explanation:
So, when a person or any object has extra electrons, it creates a negative charge. These electrons thus get attracted to positive electrons (as opposite attracts) of another object or person and vice versa. The shock that we feel sometimes is the result of the quick movement of these electrons.
The rubbing of certain materials against one another can transfer negative charges, or electrons. For example, if you rub your shoe on the carpet, your body collects extra electrons.
Answer:
d. Friction between two objects causes a transfer of electrons from one object to the other.
Explanation:
If electrons are transferred by rubbing two objects together, the result of the friction is that one object becomes positively charged by losing electrons, and the other object becomes negatively charged by gaining them. This is known as static electricity.

Identify the structures a virus can contain.
Answer:
The simplest virions consist of two basic components: nucleic acid (single- or double-stranded RNA or DNA) and a protein coat, the capsid, which functions as a shell to protect the viral genome from nucleases and which during infection attaches the virion to specific receptors exposed on the prospective host cell.

Which phrase describes a landform
Answer:
A) a feature of the landscape
Explanation:
got it right on edge
A landform is the set of forms that stand out on a plane or surface, being a feature of the landscape.
What is a landform?It is an outstanding texture of a surface that has different variations, among the most characteristic reliefs of the earth's surface are mountains, plateaus and plains.
These textures are presented in the form of irregularities and unevenness within a terrestrial or aquatic ecosystem, which provides a feature in a given landscape.
