The cell in the diagram is a plant cell because it has chloroplasts and a cell wall.
There are two types of cells animal cells, which are the ones that humans and animals have, and plant cells, which are the ones that plants and trees have. They share some organelles, but they also have some that are specific to each type.
The plant cell parts in the picture are:
Rough Endoplasmic Reticulum: it is where the ribosomes are. The synthesis of proteins happens there.Chloroplast: it is an organelle-specific of plant cells. They are in charge of photosynthesis.Cell wall: it is only present in plant cells. It surrounds the membrane.Mitochondria: It is the place that generates the energy that the cell needs.Vacuole: they are bigger in cell plants than in animal plants. It has many functions, but one is to store water.Membrane: it draws the limits of the cell.Golgi Apparatus: it is the place where proteins go to be distributed.Nucleus: it contains DNA, and it has a membrane around it.The nucleolus: is the larger part of the nucleus. It is in contact with the endoplasmic reticulum.To sum up, the plant cell has a bigger vacuole than the animal cell; it also has chloroplasts and a cell wall, which are not present in the animal cell.

Scientists can study the human genome using DNA fingerprinting.
DNA fingerprinting allows scientists to
B. break the hydrogen bonds in a gene to allow DNA to replicate itself.
c. determine the location of an abnormal gene on an individual's
chromosome.
A. prevent a gene from matching complementary bases onto a strand of
RNA.
Answers
Answer:
your answer is C.
Explanation:
DNA fingerprinting allows researchers to determine the location of an abnormal gene in a person's chromosomes.
What are the steps in DNA fingerprinting?DNA fingerprinting is a laboratory technique used to determine the likely identity of a person based on the nucleotide sequences of certain regions of a person's DNA that are unique to individuals.
DNA fingerprinting was used early in legal disputes, particularly in solving crimes and establishing paternity. It is also used to detect inherited genetic diseases and can be used to identify genetic matches between tissue donors and recipients.
In DNA fingerprinting, researchers collect DNA samples from various sources, such as hair from crime scenes and blood from victims and suspects. They then narrow down scattered sections of repetitive DNA in these samples.

under the biological species concept, what criterion is used to assign populations of organisms to the same biological species?
Answers
Answer: According to the biological species concept, organisms belong to the same species if they can interbreed to produce viable, fertile offspring. Species are separated from one another by prezygotic and postzygotic barriers, which prevent mating or the production of viable, fertile offspring. Speciation is the process by which new species form

The diagram shows the approximate amounts of carbon, in gigatons (Gt) per year, that move through the primary processes
of the carbon cycle. The numbers in yellow are due to natural processes, and the numbers in red are the result of human
actions. Based on this diagram, complete the statements.
Answers
Human activities release 9 gigatons of carbon into the atmosphere each year.
Human activities remove 5 gigatons of carbon from the atmosphere each year.
Humans’ net contribution of atmospheric carbon to the atmosphere is 4 gigatons each year.
9 gigatonnes of carbon are released into the atmosphere annually by human activity. Each year, 5 gigatonnes of carbon are removed from the atmosphere by human activity.
Thus, Each year, 4 gigatons of atmospheric carbon are added to the atmosphere as a result of human activity.
A fundamental mechanism that controls the movement of carbon dioxide and other carbon compounds between the atmosphere, oceans, soil, and living things on Earth is known as the carbon cycle. The concentration of carbon in various reservoirs is influenced by a variety of natural and human factors.
Plants and other photosynthetic creatures take up about 120 Gt of carbon each year from the atmosphere through the process of photosynthesis (yellow).
Thus, 9 gigatonnes of carbon are released into the atmosphere annually by human activity. Each year, 5 gigatonnes of carbon are removed from the atmosphere by human activity.

How many minutes are there in a 40-hour week?
A:2,000
B:2,400
C:1,400
D:1,200
Answers
Explanation:
You multiply 40 by 60 to get 2,400
There will be 2,400 minutes in a week of 40 hours. This can be calculated by the help of unit conversion of time. Thus, the correct option is B.
What is Unit conversion?
Unit conversion is the change of one form of unit to another form of unit of different system such as conversion of units of measurement of weight from gram to kilogram or milligram.
Unit conversion of one unit to another unit is used in order to have accuracy and avoiding the confusion in measurements. For example, the length of pencil is not measured in kilometers rather it is measured in centimeters or inches, which are comparatively smaller than kilometers. In such a case, one has to convert the unit of length from kilometer (km) to centimeter (cm).
The week of 40 hours can be converted into minutes by:
Number of minutes in 1 hour = 60
Therefore, the number of minutes in 40 hours = 60 × 40 = 2,400 minutes
Therefore, the correct option is B.

As a result of higher osmotic gradient outside, ____________ moves out of the thin descending limb of Loop of Henle
Answers
Answer:
is it water?
Explanation:
As a result of higher osmotic gradient outside, water moves out of the thin descending limb of Loop of Henle.
What is osmotic potential?Osmotic potential is a component of water potential whose magnitude depends on the amount of solutes present in the solution, with osmotic pressure defined as the pressure necessary to prevent osmosis from occurring.
The loop of Henle (or nephr), in anatomy, is the segment of the nephron that comes just after the proximal convoluted tubule, being a U-shaped tubular structure, with a thick and a thin portion. That can be done with the osmotic potential.

Answers
The type of fibers specialized to continue contracting for extended periods of time, as would be required in running a marathon, for example, are slow fibers.
Slow fibers have numerous mitochondria that allow you to obtain large amounts of energy aerobically.
Its contraction speed is slow, providing it with high resistance to fatigue, thus maintaining exercise for hours, typical of endurance sports (marathon).They are able to retain a longer duration of exercise at a more constant pace. These fibers are important for endurance triathletes, those who compete in medium and long distance.Therefore, we can conclude that the type of fibers specialized to continue contracting for extended periods of time, as would be required in running a marathon, for example, are slow fibers.
