Answer:
The velocity of the balloon at the bottom is 19.99 m/s.
Explanation:
Given;
mass of water balloon, m = 3.7 kg
height of fall, h = 20.38 m
The velocity of the balloon at the bottom is calculated from the law of conservation of energy;
[tex]K.E_{bottom} = P.E _{top}[/tex]
[tex]\frac{1}{2}mv^2 = mgh \\\\ v^2 = 2gh\\\\v= \sqrt{2gh} \\\\v = \sqrt{2\times 9.8 \times 20.38} \\\\v = 19.99 \ m/s[/tex]
Therefore, the velocity of the balloon at the bottom is 19.99 m/s.

In which parent could chromosomal rearrangement have made an X chromosome with 2 fur color alleles?
Answer:
Mother
Explanation:
(see image below)
According to the given situation, the mutation needs 2 X chromosomes and only the mother has 2 X chromosomes whereas a father has X and Y chromosomes.
What are the 23 chromosome pairs?Humans have 23 pairs of chromosomes, 22 pairs of numbered chromosomes, and 1 X and Y chromosome (father) and mother have (XX) chromosomes.
Each parent donates one chromosome to each pair so that offspring get half of their chromosomes from their mother and a half from their father.
Thus, the mother is an answer.

Describe how plants and animals each contribute to the survival of the other. (This type of cooperative relationship is called interdependence.)
Answer:
Plants produce oxygen which is used by animals in the process of cellular respiration, while animals produce carbon dioxide which is required for plants to make the photosynthesis process
Explanation:
In biology, interdependence can be defined as a mutual dependence relationship among two (or more) taxonomic groups. Animals and plants are cooperatively interdependent because they mutually need each other for different essential aspects of life such as food, respiration, refuge, protection, propagation, etc. For example, plants produce oxygen which is used by animals for cellular respiration (obtaining energy from this process), since most animals are aerobic organisms. Similarly, animals release carbon dioxide (CO2) when they breathe out, and CO2 is used by plants to perform photosynthesis (i.e., to produce energy and carbohydrates from this process).

I’m stumped anyone know 4 metamorphosis facts?
Answer:
Insects that have complete metamorphosis have four life stagesInsects going through their immature stage are called larvaeInsects then enter an inactive state called pupa, or chrysalis. Whilst inside the pupa, the insect will excrete digestive juices, to destroy much of the larva’s body, leaving a few cells intact.In the final stage of the metamorphosis, the insect finally breaks through the pupa emerging as a full adultExplanation:

Which fundamental force is being used in this type of
treatment?
- strong
-weak
-gravitational
-electromagnetic
Answer: Weak.
Explanation:
The complete question is:
Scientists use a substance called Iodine-131 to treat cancer. As Iodine-131 undergoes radioactive decay and emits beta particles, it kill cancer cells. Which fundamental force is being used in this type of treatment?
Well, here we have beta decay.
Beta-decay is when a beta particle (an electron or a positron) is emitted from an atomic nucleus (usually a neutron-rich nucleus). We know that beta decay is a consequence of the weak force or weak interaction (the force responsible for the radioactive decay of atoms)
Then the correct option is the second one, weak.
Answer:
(B) WEAK
Explanation:
(A) strong
(B) weak
(C) gravitational
(D) electromagnetic

Since its inception, the theory of evolution has been the subject of frequent debate. Those who oppose evolutionary theory often point to gaps in the
fossil record in an attempt to discredit the theory. Which statement would be the best counterargument as to why the fossil record can be relied upon to
support evolution?
The fossil record provides evidence that extinct species only fossilized during certain geologic eras.
The fossil record provides evidence that extinct species are genetically identical to current species.
The fossil record provides evidence of many different types of organisms, since most species fossilize well.
The fossil record provides evidence of many transitional organisms that show relationships between species
Answer:
There are lots of transitional organisms in the fossil record though it does take very specific and precise conditions for a fossil to be preserved, a deer that dies in a field will not end up in the fossil record so we are looking at a small sampling of the evidence (and a good thing too or there wouldn't be anywhere to walk with all the bones laying around)

The fossil record provides evidence of many transitional organisms that show relationship between species.

4. Living things are sometimes called "carbon-based life forms." Do you think this is a good way to describe life? Explain your answer., help me asap
Answer:
Explanation:
Yes, for a couple of reasons.
1. Carbon connects easily with other carbons.
2. Carbon forms chemical that can change and connect with other carbons even in biology or especially in Biology. If you take a brown seen and plant it where it can get water and soil nutrients, to will come up as a green plant. Think about the chemistry that goes into that. Not only that, but there are mechanisms that tell the upper part of the plant that the roots can't supply any more growth. Isn't that something? All made from Carbon.
3. The human body is a mass of Carbon based chemicals and all cells there can have different functions. Amazing isn't it? I'm a fan of the diversity of our planet and its growth.

The type of weathering seen in the pictures is mechanical weathering.
Weathering is the process by which rocks, minerals, and other geological materials are broken down and altered over time by various physical, chemical, and biological processes. It is a fundamental part of the Earth's surface dynamics and plays a significant role in shaping landscapes.
Mechanical weathering involves the physical breakdown of rocks into smaller fragments without changing their chemical composition. It increases the surface area of rocks, making them more susceptible to further weathering.

Answer:
DNA with the shortest strand will travel longer than DNA with the longer strand. In electrophoresis, the electricity will cause the DNA to move from one side of the gel to the other side. Shorter DNA strand will have a lower resistance to move in that gel so it can move further.
Explanation:
DNA with the shortest strand will travel longer than DNA with the longer strand. In electrophoresis, the electricity will cause the DNA to move from one side of the gel to the other side. Shorter DNA strand will have a lower resistance to move in that gel so it can move further.
The smallest strand of DNA will move farther than the longest strand. DNA will travel from one side of the gel to the other during electrophoresis as a result of the voltage.
What is DNA?A shorter DNA strand will pass through the gel with less resistance, allowing it to move farther.
The smallest strand of DNA will move farther than the longest strand. DNA will travel from one side of the gel to the other during electrophoresis as a result of the voltage.
A shorter DNA strand will pass through the gel with less resistance, allowing it to move farther. The publication of On the Origin of Species in 1859, Darwin has typically eclipsed Wallace.
