Explanation:
If a nucleus has eight chromosomes during interphase, how many chromosomes does it have after mitosis is complete
Answer:
8 chromosomes
Explanation:
Mitosis is the process whereby a cell divides into two identical copies of itself. This genetical identity emanates from the fact that the daughter cells possess the same kind and number of chromosomes as the parent cell.
Hence, a nucleus that has eight (8) chromosomes during interphase will possess 8 chromosome in each daughter cell at the end of mitosis. Mitosis, which consists of stages, duplicate its DNA at the interphase stage but do not increase the chromosome number. Sister chromatids are formed for each chromosome, which separate during anaphase stage, and become individual chromosome in each daughter cell.
In this case, 8 chromosome are still formed at interphase but 16 sister chromatids. These chromatids separate equally into each daughter cell i.e 8 in each cell to become individual chromosomes.
Describe how the antidote (treatment) helped Jared's cells make ATP (include the ETC and H gradient in your answer).
Answer:
By removing of poison.
Explanation:
The antidote treatment helped Jared's cells to make energy in the form of ATP by removing the adverse effect of the toxic substances which prevent the body or cell to make their functions properly i. e. production of ATP. Antidote is a medicine which removes the poison from the body that is bad for health of the body so the body is able to make their ATP again.

Answer:
D) Hemoglobin
Explanation:
The part of the blood that carries oxygen is hemoglobin.
What is Hemoglobin?The amount of hemoglobin in your blood can be measured using a hemoglobin test. Red blood cells include a protein called hemoglobin, which distributes oxygen to your body's organs and tissues while returning carbon dioxide to your lungs.
A low red blood cell count indicates a low hemoglobin level, which can be determined by a hemoglobin test (anemia). Vitamin deficiencies, hemorrhage, and chronic disorders are just a few of the numerous potential causes of anemia.
If a hemoglobin test reveals a higher-than-normal level, there are a number of possible explanations, including the blood condition polycythemia vera, high altitude living, smoking, and dehydration.
Therefore, The part of the blood that carries oxygen is hemoglobin.

explain how energy from sunlight is used during photosynthesis, then how the energy is transferred to animals that cannot harness energy directly from the sun.
help me please
Answer:
During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch. Cellulose is used in building cell walls.The chloroplasts collect energy from the sun and use carbon dioxide and water in the process called photosynthesis to produce sugars. Animals can make use of the sugars provided by the plants in their own cellular energy factories, the mitochondria. ... The energy cycle for life is fueled by the Sun.

In the essay box below, submit any observations you made, as well as the answers to the questions above. Then write a summary paragraph describing the effects of mass and distance have on the gravitational force between objects.
What happens to the force between the spheres when you increase the mass of one of the spheres?
What happens to the force between the spheres when you increase the mass of both spheres?
When you have different masses for each sphere, how does the force that the larger mass sphere exerts on the smaller mass sphere compare to the force that the smaller mass sphere exerts on the larger mass sphere.
What happens to the force between the two spheres of the same mass when the distance between the mass spheres is doubled?
What happens to the force between the two spheres of the same mass when the distance between the mass spheres is halved?
The force of attraction between 2 objects is called gravity. Why do you think that an object, like your notebook, pulled towards you? Explain your reasoning.
Answer:
So i just finished doing this project and this what i put, I hope this helps (:
Explanation:
1. When mass 1 increases the force between the objects increases. If Mass 2 decreases, the force between the objects decreases
2. An object with more mass has more/less gravitational force than an object with a smaller mass. Objects that are closer together have more/less of a gravitational force between them than objects that are further apart. The more separation two objects have, the more the force between them decreases.
3. The forces are equal (Newton's third law of motion)
4. The force between the spheres will quadruple
5. ( I dont know what this is )
6. The force of gravity exerted by the notebook on you is negligible
--The force of gravity
If there is a force between all masses, why are you not pulled toward your desk by the desk’s gravity when you walk away from it? Remember that the net force on you determines how your motion changes. The force of gravity between you and the desk is extremely small compared with other forces constantly acting on you, such as friction, the force from your muscles, Earth’s gravity, and the gravitational pull from many other objects. The strength of the gravitational force between two objects depends on two factors, mass and distance. The Mass of the Objects The more mass two objects have, the greater the force of gravity the masses exert on each other. If one of the masses is doubled, the force of gravity between the objects is doubled.
--The Distance Between the Objects
As distance between the objects increases, the force of gravity decreases. If the distance is doubled, the force of gravity is one-fourth as strong as before.
--Gravity on Earth
The force of gravity acts on both masses equally, even though the effects on both masses may be very different. Earth’s gravity exerts a downward pull on a dropped coin. Remember that every action force has an equal and opposite reaction force. The coin exerts an equal upward force on Earth. Because the coin has an extremely small mass compared with Earth, the coin can be easily accelerated. Earth’s acceleration due to the force of the coin is far too small to notice because of Earth’s large mass. The acceleration due to Earth’s gravity is called g and is equal to 9.8 m/s2 at Earth’s surface. You can calculate the force of Earth’s gravity on an object at Earth’s surface using the object’s mass and this acceleration. The formula that expresses Newton’s second law is F = ma. If you use g as the acceleration, the formula for calculating the force due to gravity on a mass close to Earth’s surface becomes F = mg.
The force between the items grows as mass 1 increases. The force between the objects reduces if Mass 2 decreases.
What is gravitational force?An item with a larger or lower mass will exert a more or less gravitational pull. The gravitational pull between two objects varies depending on how close or far they are to one another.
The force between two items weakens the more apart they are from one another. (Newton's third law of motion) the forces are equal.
Four times as much power will exist between the spheres. The notebook has very little gravitational pull on you, the gravitational force.
Therefore, keep in mind that your motion is affected by the total force acting on you.

Explanation:
How do Newton's Laws apply to the way an object moves?
Answer:
Force equals mass times acceleration.
Acceleration is directly proportional to force and inversely proportional to mass. This means that if you get pushed, the harder you are pushed, the faster you'll move (accelerate). The bigger you are, the slower you'll move.

Identify one species that is native to your geographical region in the United States. Speculate on how that species might be affected if they were to live in a warmer and wetter climate and then cooler and dryer climate.
Answer:
I live in the central region of the state of Florida in the Southeastern United States. The climate here is humid subtropical, with a defined rainy season from May through October. This season also sees afternoon thunderstorms that drop heavy but brief summer rainfall.
Florida is home to the largest population of American alligators (Alligator mississippiensis). Alligators are usually found in freshwater. They can only tolerate salt water for brief periods, because they do not possess salt glands to process the salt.
Because of strict conservation measures, the alligator (Florida’s official state reptile) has recovered from its former endangered species status. It remains under threat for habitat destruction because of the construction of water-management systems and increased levels of mercury and dioxins in the water supply. In a warmer and wetter climate, the alligator would be expected to thrive unless habitat destruction continued in that climate. In a cooler and dryer climate, the alligator would suffer from lower temperatures and loss of freshwater habitat.

In humans, as well as in many other animals and some plants, the sex of the individual is determined by sex chromosomes. The sex chromosomes are one pair of non-homologous chromosomes: XX represents a female, while XY represents a male. When a gene for a specific trait is attached to the X or Y chromosome, we say it is sex-linked, and when it is attached to the X chromosome, we say it is X-linked. Alleles for these linked traits, such as hemophilia or color blindness, crosses, may be recessive or dominant.
Hemophilia is an X-linked, recessive trait. The recessive allele for hemophilia is actually a mutated version of the normal alllele but it can still be passed on through generations. Imagine a female is a carrier for hemophilia; her genotype is XHXh. She is married to a man who does not have hemophilia. What conclusion is NOT valid concerning this genetic cross?
A) 0% of female offspring will have hemophilia.
B) 100% of the male offspring will have hemophilia.
C) There is a 50% chance that male offspring will have hemophilia.
D) The chance that female offspring will have the allele for hemophilia is 50%.
Answer:
B isn't valid
Explanation:
As you observe from the diagram above, the second offspring (a male) doesn't have haemophilia disproving option B

Photosynthtic and multicellular correctly describes distinguishing characteristics of the Kingdom Plantae.
What are the characteristice of kingdom Plantae?Kingdom Plantae includes all the plants. They are eukaryotic, multicellular and autotrophic organisms. The plant cell contains a rigid cell wall. Plants have chloroplast and chlorophyll pigment, which is required for photosynthesis.
They are non-motile. They make their own food and hence are called autotrophs. They reproduce asexually by vegetative propagation or sexually. These are multicellular eukaryotes.
Kingdom Plantae is broadly composed of four evolutionarily related groups: bryophytes (mosses), (seedless vascular plants), gymnosperms (cone bearing seed plants), and angiosperms (flowering seed plants).

Explain why red blood cells can be maintained in an intact state by keeping them in a normal saline solution.
Answer:
The solution is isotonic.
Explanation:
Saline solututions are mixtures of salt and water. In a normal saline solution, red blood cells maintain their shape. This is because the saline solution is isotonic. Essentially it has the same concentration as inside the red blood cell.
The water does not move down a particular gradient, thus the shape remains unchanged.
Red blood cells can be maintained in an intact state by keeping them in a
normal saline solution because the solution is Isotonic.
Isotonic solutions possesses the same osmotic pressure or equal
concentration of solutes and this aids free movement of solute in and out of
the cell via the semi-permeable membrane.
The solution must be isotonic to enable the red blood cells remain intact
thereby preventing swelling or shrinking of the cells.
