Answer:

Explanation:

This question seeks to classify the statements made into Theory, Hypothesis, law or fact.

An hypothesis is a scientific guess which when experimented is conducted, a theory is carefully proposed to explain this experiment and the conclusions thereof. And a law is a certain description (usually proposed by an individual or group of individuals) of a particular phenomenon that must undergone a certain level of scientific inquiry. A fact is however a truthful statement of assertion that could be easily verifiable.

(2) Water freezes at 32° F

Fact (because water freezes at 0°C which is same as 32° F and be easily verified)

(3) The solar system formed from a disk of spinning disk of gas and dust

Theory (This is one of the theories that suggests the formation of the solar system)

(4) F = ma meaning Force = mass × acceleration

Law (This is a mathematical representation of the Newton's second law of motion)

(5) The Universe is expanding

Theory (This is the cosmological theory proposed by Edwin Hubble using the relationship between the speeds of distant galaxies and their respective distances from Earth)

(6) Newton's Laws of Motion explain why orbits are ellipses

Fact (because the Newton's laws of motion indeed provided explanation about the earth's movement around the sun which shows/describes how earth is being pulled into an elliptical orbit)

(7) The Universe was created at an event known as the Big Bang

Theory (This is popularly known as the Big Bang Theory)

(8) More babies are born at the full moon

Hypothesis (This is just a guess and still requires a scientific experiment to back it up)

(9) Matter is composed (made up of) atoms

Theory (This is one of the postulates of the Dalton's atomic theory)

(10) Sections of the earth's crust move around over the mantle as a result of convection

Fact (This is known as mantle convection)

(11) Darwin explained how life on Earth evolved over time by examining the fossil record

Theory (This statement describes what is known as the Darwin's theory of evolution)

What happens that makes rain start to fall from a cloud?

Shkiper50 [21]

Answer:

when water vapor turns into clouds

Explanation:

Water vapor turns into clouds when it cools and condenses—that is, turns back into liquid water or ice. ... In the cloud, with more water condensing onto other water droplets, the droplets grow. When they get too heavy to stay suspended in the cloud, even with updrafts within the cloud, they fall to Earth as rain.

In garden peas a pure line that is tall with purple flowers is crossed to another pure line that is short with white flowers. Th

defon

Answer:

See the explanation

Explanation:

Answer 1.

As given that in F1 all are short and white then it can be said according to Mendel's law that short and white are dominant over tall and purple.

Let S for short s for tall and W for white and w for purple allele.

So the genotype of short purple will be Ssww or SSww. So In first case Ssww self crossed then resultant offsprings will be,

................ Sw .................... sw

Sw ........ SSww ............. Ssww

sw ........ Ssww .............. ssww (tall and purple)

So from this 1/4 will be tall and purple while 3/4 will be short and purple.

In second case SSww only short purple progeny will appear.

Answer 2.

2. a) The female progeny will not show any trait because there are two X chromosome in females , so female offspring can be carrier but not show any trait in case of X- linked trait.

2. b) Half of male offsprings show trait because X is inherited from mother. So the chance of having X-linked recessive allele is 1/2.

2. c) The chance of having X linked affect allele in daughter is 1/2. So the chance of inheriting that X to son will be 1/2 so in total there is chance of 1/4 that son will be affected.

2. d) the chance of first child show this trait will be 1/4 in case of male offspring while 0 in case of female offspring.

Hope this helps!

EARTH'S HISTORY

scoundrel [369]

Answer:

Around 100,000 years ago, the Earth was going through a period of Ice Age. While the Glacial Period was not in full effect, it is reasonably concluded by researching the ending of the Ice Age and other Glacial Periods that the Earth was considerably colder than it is right now.
