Answer:
The correct answer is - B. Enzyme.
Explanation:
RubisCo or ribulose bisphosphate carboxylase is an enzyme and most abundant protein on the earth that catalyzes the formation of the sugars from the CO2 by the photosynthesis process.
As it is given that in absence of the RuBisCo enzyme the cells plants or the photosynthetic organisms are not able to produce as much food as they produce in presence which means it has an essential role in increase the photosynthetic process to produce the food. By this, we can say it is an enzyme that helps in the process of photosynthesis.
What is water called when it has a high concentration of iron, magnesium, or
calcium?
hard
a lake
groundwater
soft
Answer:
I think Hard
Explanation:
Hard water, water that contains salts of calcium and magnesium principally as bicarbonates, chlorides, and sulfates. Ferrous iron may also be present; oxidized to the ferric form, it appears as a reddish brown stain on washed fabrics and enameled surfaces.
If a truck goes 30 miles in 30 minutes, what is its average speed? *
Answer:
The average speed is 60 miles per hour or 1 mile per minute.
Explanation:
If you multiply 30 by 2 to find the miles per hour, you also have to multiply 30 miles by 2. This results in 60 miles per hour. If you want to find the miles per minute, you divide the 30 minutes by 30. You have to do the same to the miles, so the average speed could also be 1 mile per minute.
An epeirogenic change:
creates very high mountians
leaves the crust undeformed
results in highly volcanic regions
occurs when rock layers are lifted out of sequence
Answer:
leaves the crust undeformed
Explanation:
An epeirogenic change is one that leaves the crust undeformed. They are notable for creating the continental craton where little to no tectonic activities forms.
These events causes upheavals and depression of the ground surface. Orogenic change causes deformation of the surface. They create blocks of mountain.Answer:

Imprinting disorders do not involve changes in DNA sequence, but only the methylated state of the DNA. Does it seem likely that imprinting disorders could be treated by controlling the maternal environment in some way, perhaps by dietary changes?
Answer:
It is confirmed that epigenetic changes play a significant role in imprinting disorders and food like folic acid, vitamin B12 and other certain food can affect the DNA methylation process.
Demethylation of DNA has been effective to human disorders even though methylation is an important and natural process, may be useful for regulating one gene which can lead to various changes that need to be avoided.

1. Why is it important that the same mass of each food is analyzed?
Answer:
Explanation:
In any form of experimental research where data is being analyzed, there needs to be only one variable present and each group in the experiment needs to have the same factors and environment as the others. That way the single variable can be isolated and the data properly analyzed. That is why it is important for the mass of each food to be the same, since the foods are already different variables the rest of the factors in the experiment need to be the same including the mass of each food.

Argue whether or not pandas are at the top of their food chain in the following scenario.
Pandas are herbivores that live in the mountainous regions of China. They are peaceful and docile and spend about 18 hours a day eating bamboo. They have only one natural predator: the leopard. However, adult pandas are so large that they are never hunted. Leopards will eat only baby pandas that are left alone, and this occurrence is very rare. Most baby pandas are killed accidentally when their mothers roll over.
In this ecosystem the Leopard usually eats the Giant Panda bear cubs because the adult pandas are very intimidating out in the wild because of their size. The Leopard is then eaten by the Bengal Tiger which in this situation is the Tertiary Consumer and is at the top of the Panda Bears food chain.
The Panda comes under the secondary consumer, as it uses photosynthesis to produce its food – Bamboo. Cubs become a prey to other animals such as Leopards and tigers, which are known as the primary consumer. However adults intimidate other predators because of their great size.

identify and explain if cloning is a form of asexual reproduction or sexual reproduction
[Written response] [45 POINTS!!!] Please help
Answer:
Organism cloning. Organism cloning (also called reproductive cloning) refers to the procedure of creating a new multicellular organism, genetically identical to another. In essence this form of cloning is an asexual method of reproduction, where fertilization or inter-gamete contact does not take place.

What is the structure of prokaryotic chromosomes
Answer:
1. Prokaryotic chromosomes are found in the nucleoid of prokaryotic cells, and they are circular in shape.
Unlike eukaryotic cells, prokaryotic cells don’t have a membrane-bound nucleus. Instead, their genetic material can be found in a region of the cytoplasm called the nucleoid. A prokaryotic cell typically has only a single, coiled, circular chromosome. However, there are a few prokaryotes that have more than one—Vibrio cholerae, the bacterium that causes cholera, has two circular chromosomes.

Prokaryotic Chromosome
Prokaryotic cells typically have a single, circular chromosome located in the nucleoid.

2. Each chromosome contains a molecule of DNA that is supercoiled and compacted by nucleoid-associated proteins (NAPs).
Prokaryotic cells may have only one chromosome, but that one chromosome is a very long DNA molecule that must be condensed to fit inside a tiny space. In a eukaryotic cell, DNA wraps around clusters of histone proteins. However, most prokaryotic cells don’t use histones to help with DNA storage. (Some Archaea do, but they are the exception, rather than the rule.)
Like eukaryotic DNA, prokaryotic DNA undergoes supercoiling, but it is not wound around histone clusters first. Supercoiling uses the application of tension to twist a DNA molecule, so it wraps around itself, creating loops.
The folding of prokaryotic DNA is facilitated by nucleoid-associated proteins (NAPs) instead of histones. NAPs are proteins within the nucleoid that can bind to the DNA molecule, introducing bends and folds, and they are involved with processes such as DNA replication and transcription.
3. Prokaryotic cells are haploid, meaning they do not have chromosomes that occur in homologous pairs.
Most prokaryotic cells have just one chromosome, so they are classified as haploid cells (1n, without paired chromosomes). Even in Vibrio cholerae, which has two chromosomes, the chromosomes are unique from one another. That is, they are not a homologous pair, because they don’t contain the same genes in the same locations.
Many prokaryotes, such as bacteria, reproduce via binary fission. This is a method of asexual reproduction that is similar in its end result to mitosis—two daughter cells result, each with the same number of chromosomes as the parent cell. However, when bacteria undergo binary fission, no mitotic spindle forms. In addition, the replication of the prokaryotic cell’s chromosome can occur during the fission process.
4. Prokaryotic cells can also carry small molecules of DNA called plasmids.
Plasmids are small, circular DNA molecules that contain the cell’s nonessential genes. Although plasmids can occur in a variety of sizes (ranging from around a thousand base pairs to hundreds of thousands), they usually only have a small number of genes. Antibiotic resistance is a trait that is frequently attributed to genes on plasmids.
In addition to their single chromosome, prokaryotic cells often have small, circular DNA molecules called plasmids.
The genetic material of plasmids is separate from that of the cell’s main chromosome, and they can replicate independently of that chromosome. When a prokaryotic cell with a plasmid divides, the daughter cells each receive a copy of the plasmid, along with its regular chromosome.
5. Prokaryotic and eukaryotic chromosomes differ in their shape, size, number, and location within the cell.
Here’s how the characteristics of eukaryotic and prokaryotic chromosomes compare.

Shape Linear Circular
Size Large Small
Number Multiple Single
Location Nucleus Nucleoid (region in cytoplasm)
Storage proteins Histones Nucleoid-associated proteins

Look at the map below. The mountains in the Pinnacles National Monument and the mountains at Tejon Pass were once located next to each other and
a part of the same mountain range Now however, they are separated by over 240 kilometers Explain how the mountains at Pinnacles National Monument
and the mountains at Tejon Pass became separated from each other koi
Answer:
The mountains at Pinnacles National Monument and the mountains at Tejon Pass became separated from each other after suffering a transforming process, in which plates slid laterally against each other along the fault.
Explanation:
The tectonic plates theory is based on the continual movements of the crust and might explain the movement of the different plates, and their directions and interactions.
Plates are limited by three different ridges or borders that differ in the type of movement they produce.
Divergent limits: two plates get separated.Convergent limits: These movements occur when two plates collide.Transforming limits refer to geological structures related to the seafloor expansion and associated in general with the oceanic ridge, although they might also occur in the continental plate. These limits are known as geological faults, where no rocky material is either destroyed or formed. When the plates move and produce a displacement of one transforming limits from side to side, earthquakes occur. The movement breaks the crust and originates pronounced fractures. The San Andrés fault is an example of these plate ridges.A subduction process first originated all the mountains. This process took a lot of time and it in different stages. But once it concluded, a new process followed the first one. The transforming process, which occurred when the Pacific plate collided against the occidental ridge of the North American plate until it broke along the tension line. This process involves a movement of plates in which they slide laterally against the others along a line known as a fault.
As you can see on the map, the Pinnacles National Monument and the mountains at Tejon Pass are placed on opposite sides of the fault line. At first, they were together, and then by the transforming process, the plates moved along the fault separating them.
