Daughter cells formed by mitosis have exact copies of the parent cell's DNA. What process ensures that is possible?
Daughter cells formed by mitosis have exact copies of the parent cell's DNA. The anaphase process ensures that is possible.
What is mitosis?Cell division occurs during mitosis. All eukaryotic cells go through the process. There are four stages to the process. The cell divides during the procedure. A daughter cell that is identical to the parent cell is created.
Prophase: This is mitosis's initial phase. At this point, the chromosomes begin to compress and the cell begins to break.
This is the second phase, or metaphase. The chromosomes align in the spindle fiber during this stage, and a checkpoint is also established.
Anaphase: At this time, the sister chromatids separate, align, and the chromosomes divide.
The final phase is known as the telophase. The nuclear membrane developed as the nucleus closed.
Therefore, the process that ensures the daughter cells formed by mitosis have exact copies of the parent cell is the anaphase.

A. generation
B. population
C. individual
Answer:
B. population
Explanation:
CORRECT
Evolution is any change in the heritable traits within a population. Therefore, option (B) is correct.
What is evolution?Evolution is the process by which populations of organisms change over time through the gradual accumulation of genetic variations. It is the central concept of modern biology and provides a framework for understanding the diversity of life on Earth.
Evolution occurs through the mechanisms of natural selection, genetic drift, gene flow, and mutation. Over time, genetic variations that confer a survival advantage in a particular environment become more common in a population, while those that are detrimental or neutral are selected against.
This process can lead to the emergence of new species, as well as the extinction of others. The study of evolution has practical applications in fields such as medicine, agriculture, and conservation, and helps us understand our place in the natural world.

you have two bean burritos with the same ingredients. One burrito weighs 0.3 pounds, while the other weighs 0.5 pounds. After microwaving each of them for one minute, which burrito will be hotter? Explain your answer.
Answer:
the one that weighs less
Explanation:
the one that weighs less has less of the amount of ingredients in it which takes less long to cook and heats up faster
Answer:
0.3 pounds
Explanation:
I say that because since there is less weight on one of them, it doesn’t have to be cooked as long, or else it may get cooked TOO uh since it weighs less, while the other one may be cooked perfectly since there is more to cook.

1. What two reactants enter the mitochondrion?
2. Compare the reactions in mitochondria with glycolysis.
1. How does a cell obtain energy?
2. Under what conditions does fermentation occur in a cell?
3. If a cell could perform both cellular respiration and fermentation, which process would benefit the cell more?
Answer:
1.NADPH2 and FADH2 , and O2
Explanation:
NADPH2 and FADH2 get oxidized in the electro transport chain into NADP+ and FAD+ and water and oxygen and yield 3 ATP molecules and 2 ATP molecules per each molecule respectively
Following are the answers:
The two reactants that enter the mitochondrion are pyruvate, the end product of glycolysis, and oxygen.In the mitochondria, pyruvate and oxygen undergo a series of reactions called cellular respiration, which produces energy in the form of ATP. This process is more efficient than glycolysis, which only produces a small amount of ATP.A cell obtains energy through a variety of processes, including cellular respiration and fermentation.Fermentation occurs in a cell when there is a lack of oxygen, such as in anaerobic conditions.In general, cellular respiration is more efficient than fermentation in producing ATP, but fermentation is a useful process for cells to produce ATP when oxygen is not available.What is mitochondria?Mitochondria are organelles found in the cells of most eukaryotic organisms, including plants, animals, and fungi. They are often referred to as the "powerhouses" of the cell because they are responsible for producing the majority of the cell's supply of adenosine triphosphate (ATP), which is used as a source of chemical energy.
Mitochondria are membrane-bound structures that contain their own genetic material, separate from the cell's nucleus, and are responsible for their own replication. They have unique characteristics that allow them to produce energy through the process of cellular respiration, a series of reactions that convert the energy from food molecules, such as glucose, into ATP. This process is one of the most important biological processes in living organisms, as it allows cells to perform their functions and sustain life.

False. At the freezing point, the particles in an object have some kinetic energy.
False. On the Celsius temperature scale, there are negative numbers.
True. The more particles an object has at a given temperature, the more thermal energy it has.
False. Object A is much larger than Object B, but both are made of the same material. If both objects are at the same temperature, the thermal energy of Object A is not the same as the thermal energy of Object B.
False. When heat is absorbed by an object, the speed of the particles in the object is changed.
Explanation:
The temperature is defined as the measure of hotness and coldness.It is measured in terms of degrees Celsius, Kelvins, degrees Fahrenheit.There are negative numbers on the Celsius temperature scale and Fahrenheits temperature scale but not on the Kelvin temperature scale.It is a measure of the average kinetic energy of the particles of the object.The hotter the object, the higher will be the kinetic energy of the particles of the object, higher will be the value of temperature. The colder the object, the lower will be the kinetic energy of the particles of the object, lower will be the value of temperature.The object with more mass will have more particles and more will be the kinetic energy associated with the particles.When heat is added to an object to raise its temperature the kinetic energy of the particles increases. As kinetic energy is directly linked with speed or velocity.So from this, we can conclude that :
At the freezing point, the particles in an object have some kinetic energy.
On the Celsius temperature scale, there are negative numbers.
The more particles an object has at a given temperature, the more thermal energy it has.
Object A is much larger than Object B, but both are made of the same material. If both objects are at the same temperature, the thermal energy of Object A is not the same as the thermal energy of Object B.
When heat is absorbed by an object, the speed of the particles in the object is changed.

Sperm are produced in the glands sperm duct. testes. urinary bladder.
The testes. A pair of male reproductive glands called the testes can be found in the scrotum, which is a sac-like structure that is found on the exterior of the body.
Sperm and the male hormone testosterone are both produced in the testes, which are responsible for the function of the testes. When the sperm have been created, they pass via a number of ducts, such as the vas deferens, the epididymis, and the ejaculatory ducts, before being expelled from the male organ during the process of ejaculation. On the other hand, the urine bladder is a component of the urinary system, but it does not contribute in any way to the creation of sperm.

Select all that apply.
carbohydrates
glucose
proteins
O nucleic acids
[tex] \huge \purple{\tt{Answer:}} [/tex]
glucose
The molecule here that contains only carbon, hydrogen, and oxygen is Glucose. So the correct option is B.
What is glucose?Glucose is a monosaccharide or simple sugar. It is a kind of sugar found in honey and fruits. Glucose is the major sugar present in our body.
It is the main source of cellular energy utilized in the process of cellular respiration. Thus, it helps in proper cell functioning and metabolism.
Starch molecules are composed of various monomers of glucose. They are the polysaccharides of glucose. The structural formula for glucose is C₆H₁₂O₆. This means that glucose is only composed of carbon hydrogen and oxygen atoms.
Glucose is a type of Carbohydrate but there are other kinds of carbohydrates that contain elements like nitrogen and sulfur. Proteins and nucleic acids also contain other elements like phosphate, nitrogen, and sulfur.
Thus only glucose is composed of oxygen, carbon, and hydrogen.
Therefore the correct option is B.
