Answer:
Explanation:
Like theories, scientific laws describe phenomena that the scientific community has found to be provably true. Generally, laws describe what will happen in a given situation as demonstrable by a mathematical equation, whereas theories describe how the phenomenon happens.
I need to know about hypothesis
Answer:
A hypothesis a prediction or a educational guess (or in other words, a theory) that might happen in a experiment weather it's right or wrong. It's important to make hypothesis to learn from your mistakes and analyze why you got it wrong and why it make you think that (wrong hypo). A hypothesis can also help you learn more about the subject.

"Crossing Over" occurs in Prophase 1 of Meiosis.
True
False
Answer:
true
Explanation:
Answer:
Crossing over occurs during prophase I of meiosis before tetrads are aligned along the equator in metaphase I. By meiosis II, only sister chromatids remain and homologous chromosomes have been moved to separate cells. Recall that the point of crossing over is to increase genetic diversity.

When ice freezes, the water around it becomes saltier and colder. _______, it's density increases.
A Therefore
B On the other hand
С In contrast
D Especially
When ice freezes, the water around it becomes more saline and colder. Therefore, its density increases. Hence, the correct option is (A).
What is Density?
Density is defined as the mass per unit volume of a substance and is denoted by ρ, although the Latin letter D may also be used.
Density is defined as mass divided by volume: [tex]{\displaystyle \rho ={\frac {m}{V}}}[/tex]
where ρ is density, m is mass, and V is volume. It has the units of mass divided by volume such as grams per centimeters cube [tex](g/cm^3)[/tex] or kilograms per liter (kg/l).
When water changes from a liquid to a solid state that is liquid in the form of ice, its density will increase as it becomes saltier and colder.
Thus, when ice freezes, the water around it becomes more saline and colder. Therefore, its density increases. Hence, the correct option is (A).

What is true about the current extinction rate?
A.
It’s slower than the earlier mass extinction rate.
B.
It’s primarily attributed to human intervention.
C.
It’s attributed to natural environmental changes.
D.
It’s necessary for evolution.
E.
It’s affecting few species.
Answer:
its b
Explanation:
Extinction is primarily attributed to human intervention. So, the correct option is B.
What is Extinction?The extinction is defined as the end of a particular type of organism or a set of types, typically a species. Although the ability to reproduce and bounce back may have been lost earlier, the death of the last member of the species is usually considered as the moment of extinction.
Extinction is the term used to describe the extinction of an entire species. In that it has allowed for the emergence of new species and the ascent of others, extinction has both advantages and disadvantages. Since most species have been driven to extinction by human activity, humans have had a significant impact on the pace of extinction. The main cause is thought to be human activity.
Therefore, the correct option is B.

A pelican is hunting for fish as it flies above the surface of the water. Why must the pelican alm for the fish in a slightly different place in the water than where the fish appears to be
located?
Answer:
I'm not sure but maybe because if the pelican goes exactly where the fish is the fish will naturally move forward to escape so instead of catching the fish the pelican would get a mouth full of water. If the pelican aims for a spot a little different then where the fish actually is the pelican can might catch it because the fish went to its direction. (sorry if that's not correct)

The energy from the sun is produced in the core through the process of nuclear fusion. The photons travel through the sun and are released as radiation which travels to the earth. How long does it take to reach the earth?
Answer:
8 min 20 seconds
Explanation:
Radiation from the sun travels as light through the vacuum of space. Therefore, it is travelling at the speed of light which is roughly 300,000 km/s. If we divide this speed by the average distance between the Sun and the Earth (150,000,000 km) we would get a total of 500 seconds. We can now turn this total time into minutes which would be roughly 8 min and 20 seconds. Therefore, it would take a total of 8 min 20 seconds for radiation from the Sun to reach Earth.
