The following section explains the description and as per the given situation.
Explanation:
Throughout the 1920s, Walter Garang proposed whether vertebrates formed from some kind of pedomorphosis simplified such as lava. Garstang mentioned whether attaining sexually mature would just have frozen several tunicates throughout their larval stages at a much more early development stage, in which they'll replicate.The diploid chromosome number in a certain species of fish is 20. How many chromosomes would normally be found in bone cell of this fish?
A. 10
B. 20
C. 23
D. 40
Answer:
The answer is 20
Explanation:
When the diploid number of chromosomes in a given cell is 20, the normal number of chromosomes found in bone cell of this fish Is also 20.
When we refer to chromosome numbers as being diploid, what we mean it's that each cell has two copies of each chromosome. These are known as homogamous chromosomes because they contain similar information.
For most eukaryotic cells and organisms, chromosomes are found in diploid pairs. This layout of diploid chromosomes is essential for the process of cellular multiplication. Therefore, the normal situation if for all cells to contain diploid numbers, so when the question states that one cell has 20, we can infer that all cells have 20 diploid chromosomes.

A roller coaster containing four cars is accelerating at -15 m/s2 before it comes to an abrupt stop at the end of the ride. The mass of one car is 200 kg. How much force was exerted on the roller coaster to bring it to a stop
Answer:
F = -3000 N
Explanation:
Given that,
Mass of the car, m = 200 kg
A roller coaster containing four cars is accelerating at -15 m/s²
We need to find the force exerted on the roller coaster to bring it to a stop. Let F is the force.
F = ma
Putting all the values,
F = 200 kg × (-15 m/s²)
= -3000 N
So, the force us 3000 N and it act in opposite direction.

3. In the sim molecules moved faster when it was warm and slower when it was cold. This can explain why the food coloring spread faster in warm water because the molecules were moving faster causing the food coloring to quickly spread through out the water.
Sorry if its wrong
The food color mixes more easily with the warm water than with the cold water, as the warm water has less density than the cold water, which allows the diffusion of the color in the water.
What role does food coloring play in the lives of organisms?It has numerous negative effects on the organism, including allergic reactions to certain food coloring, increased hyperactivity in children, disruption of the endocrine system, negative effects on reproduction and development in animals, and so on. Aside from that, the animals may exhibit symptoms of liver and kidney failure due to its toxicity.
Hence, the food color mixes more easily with the warm water than with the cold water, as the warm water has less density than the cold water, which allows the diffusion of the color in the water.

A small family farm has 230 acres of farmland to grow corn . If each acre yields 63 bushels of corn and each bushel can be sold at $9.00, how much does the farm make corn per year?
Answer:
$130,410
Explanation:
According to this question, a small family farm has 230 acres of farmland to grow corn. Each acre yields 63 bushels of corn i.e 1 acre = 63 bushels of corn
Also, each bushel can be sold at $9.00 i.e. 1 bushel = $9.00
If 1 bushel = $9.00
63 bushels = 63 × 9 = $567
Since 63 bushels of corn = 1 acre, it means that $567 is made on one acre.
Hence, on 230 acres, 230 × 567 = $130,410 will be made on corn per year
Which type of dating method can be used on rock layers by applying the law of superposition
Answer:
Relative dating
Explanation:
The Law of Superposition of rocks states that the layer of rock which is below is older than the one above it.
Therefore, the type of dating method that can be used on rock layers by applying the law of superposition is relative dating because it is used when the rocks have been kept in their original sequence and not tampered with.
What's the new peptide chain when the new DNA segment is translated?
Answer:
The correct answer is - Methionine, serine, histidine, aspartate, glycine
Explanation:
The new segment of DNA is: 3'-TACAGGGTGCTACCCACT-5', which performs two processes to form a peptide chain, transcription, and translation. In transcription, the DNA segment is encoded to an mRNA molecule which has its complementary sequence to DNA sequence.
New DNA strand: 3'-TACAGGGTGCTACCCACT-5'
mRNA sequence: 3'-AUGUCCCACGAUGGGUGA-5'
The translation of this mRNA would be on the basis of chart
AUG - Methionine (start codon)
UCC - serine
CAC - histidine
GAU - aspartate
GGG - glycine
UGA - stop codon
The peptide chain would be - Methionine, serine, histidine, aspartate, glycine

In which of Studies 1 and 2 did some of the fruit flies live for more than 75
days, and what diet were those fruit flies fed?
Study 1; 05% SY medium
O Study 1; 15% SY medium
Study 2:05% SY medium
O Study 2; 15% SY medium
Answer: Study 2: 05% SY medium
Explanation:
The x axis on each graph shows the number of days that has elapsed while the y axis shows the percentage of fruit flies that are still alive. In the Study 1, we notice that all the fruit flies had died off by the 55th day.
In Study 2, we then see that some fruit flies lived past 75 days. Those were fruit flies which had been put in the tube that had only 5% SY medium which contains 5% sugar and 5% killed yeast.

Which diagram best represents the cycling of respiratory and photosynthetic gases in green
algae?
Answer:
The correct answer is - option D.
Explanation:
In algae or any other photosynthetic organism, there is the internalization of carbon dioxide gas in the reaction with water in the presence of sunlight to produce sugar molecules and oxygen gas in the atmosphere. So, photosynthesis is the process that releases or produces oxygen gas.
In cellular respiration (aerobic) the product of photosynthesis, glucose molecules, and oxygen react to produce the energy and releases carbon dioxide and water as byproducts.
So, the correct answer is - option D.

What is a protist as in the Protist Kingdom?
Answer:
A protist- is any eukaryotic organism (that is, an organism whose cells contains a cell nucleus) that is not an animal, plant, or fungus.
Explanation:
The protist kingdom comprises unicellular eukaryotes.
What organisms are in the protist kingdom?All living organisms have been divided into two broad groups known as eukaryotes and prokaryotes. This classification is based on the complexity of their cell structures. The prokaryotes lack organelles and a true nucleus while these structures are present in the eukaryotic cell.
Based on this simple parameter, in the Five Kingdom system of classification, unicellular prokaryotes were known as Monera and unicellular eukaryotes were known as Protists.
Therefore, any single-celled organism with a true nucleus and membrane-bound organelles is a part of this kingdom of classification.
Fungi, Plantae and Animalia are other classified kingdoms. They are all multicellular with some exceptions. Fungi are saprophytic, plants are photosynthetic and animals are heterotrophic.
Some examples are amoeba and paramecium.

This is a solid substance that is composed of minerals. This describes the dynamic changes between sedimentary, metamorphic, and igneous substances. This occurs are mid-ocean ridges where a new oceanic crust is formed and then slowly moves away from the ridge.
Explanation:
The "dynamic changes" between sedimentary, metamorphic, and igneous substances refer to the processes by which these rock types are transformed from one another over time and explain the geological process.
What is the significance of the different rocks?There are different types of rocks, such as metamorphic rocks, which form from the alteration of pre-existing rocks, such as metamorphic rocks, through heat, pressure, etc., and igneous rocks, which form from the solidification of magma or lava. Sedimentary rocks form from the accumulation of sediments, such as sand and gravel, and all these rock types explain the complex geological processes.
Hence, the "dynamic changes" between sedimentary, metamorphic, and igneous substances refer to the processes by which these rock types are transformed from one another over time and explain the geological process.
