Mendel also developed the law of
dominance. He did many experiments
with pea plants. This is how he came
up with the law. It shows how certain
traits come to be. One allele is
dominant. It exerts a greater influence.
He based this on an uncertain belief
that each plant carried two trait units.
One of them dominated the other.
Which sentence from this paragraph explains what a dominant allele does?
A. Mendel also developed the law of dominance
B. He did many experiments with pea plants
C. It exerts a greater influence
D. He based this on an uncertain belief that each plant carried two traits
Answer:
They mask the recessive alleles
The Big Bang Theory is a hypothesis that states that all matter
and energy were at one time compressed into a small volume
and then _________
Answer:
I’m not sure how they want you to answer the fill in blank.
Explanation:
The Big Bang is a theory where 14 billions years ago all matter and energy in the universe was compressed into an extremely small volume that exploded and began expanding in all directions.
The big bang theory is a hypothesis that states that all matter and energy were compressed into a small volume at one time and then expanded outward.
What is Big Bang Theory?The big bang model of the universe can be described as the model to identify the beginning of the universe. The big bang model is a cosmological model which is described by the software development life cycle.
The Big Bang theory is the dominant model of the observable universe from its beginnings to large-scale evolution. This model explains how the universe is expanded from a state of high density and temperature. It provides an explanation for phenomena, such as cosmic microwave background radiation, the abundance of light elements, and large-scale structure.
Due to the big bang as we know, the universe has been created existing about 12 - 15 billion years ago. According to the theory that the Big bang was a gigantic explosion that formed all of the energy and mass in less than a second in the universe.

Which of the following factors does NOT affect surface currents?
A. Coriolis effect
B. density
C. continental deflection
D .wind
The only factors that doesn't affect surface current from the question is B:
density.
Surface currents can be regarded as current that is been formed as a result of Earth's rotation as well as changes in temperature.Surface currents is know as one of the determinant for climate. These currents is responsible for the bringing of warm water from the equator then transfer it to the cooler parts of the ocean as a result of this heat energy is transferred.Some factors that influence surface current are; Coriolis effect : This also aid the movement of the currentcontinental deflection : this helps the deflection of the currents from the continental land masses.wind : without wind there cannot be transfer of the warm water from the equator to the part of the ocean that is cool.Therefore, Option D is correct because density does affect the surface current.

What is the natural reason for the rising surface temperatures of the Pacific Ocean, drought in the western United States, and flooding on the Pacific coast of South America? Is it the Jet Stream, the Gulf Stream, La Niña, or El Niño? This is a science question about weather.
Answer:
El Niño
Explanation:
The natural reason for the rising surface temperatures of the Pacific Ocean, drought in the western United States, and flooding on the Pacific coast of South America Is the El Niño.
El Niño is a climate pattern that happens when there is an unusual warming of the surface temperatures of the Pacific Ocean. This occurs at an interval of two to seven years
During El Niño, the surface waters of the Pacific Ocean become warmer than average and this is as a result of the weakness of trade winds which blows over the entire Pacific Ocean. This makes the atmospheric pressure above the ocean to decrease.
El Niño brings rainfall nd flooding to South America and droughts in the western United States

value. Be sure to discuss one chemical or product that is made from potassium,
it's benefit to humans and how it is made.
Answer:
Potassium is a very high reactive metal. Exposed to water, it explodes with a purple flame. Potassium is involved in the health of cells and of blood vessels, so its reactivity has increased values, being used by scientists for blood pressure as well as lethal injection, enough could cause your heart to stop. Take bananas for example, they contain potassium, enough for humans.
