Eukaryotes have both the mitochondria and chloroplasts.
Eukaryotes are regarded as multi-cellular organisms with a well defined
nucleus. They have a nuclear membrane which houses the nucleus in a
different compartment from the cytoplasm.
Plants and animals are examples of eukaryotes and the plants possess
chloroplasts for photosynthesis while the mitochondria is where energy
generating activities of the cells take place for both plants and animals.

what is a trophic level
each of several hierarchical levels in an ecosystem, comprising organisms that share the same function in the food chain and the same nutritional relationship to the primary sources of energy.
Answer:
The trophic level of an organism is the position it occupies in a food web. A food chain is a succession of organisms that eat other organisms and may, in turn, be eaten themselves.
People's choices can have a positive or negative effect on their health. Describe one positive choice and one negative health choice a person could make. Be sure to explain how each could impact an individual's health and, if applicable, the health of others.
Answer:
try eating foods that have a unique taste that may appeal to you but are still healthy
Explanation:
One positive choice someone can make would be drinking more water. One negative choice someone can make would be smoking too many cigarettes. Drinking more water can boost your health by decreasing chances of digestive problems and increasing blood pressure. Also, smoking too many cigarettes can lead to heart diseases, lung diseases, and diabetes.

If you are pushing a box toward your friend with a force of 20 N, and your friend is pushing the box
toward you with a force of 30 N, what will happen to the box?
The box will move toward your friend with a force of 10N.
The box will move toward you with a force of 50 N.
The box will move toward you with a force of 10 N
The box will move toward your friend with a force of 50 N.
Answer:
The box will move toward you with a force of 10N
Explanation:
If you and your friend are pushing the same box with the same amount of force, those two forces will balance each other out, and the box won't move. In the question, 20N will cancel each other out, and there will be 10N. Your friend is pushing the box with more force than you, so it will move toward you with the remaining force of 10N
How are carbohydrates broken down by living organisms?
Answer:
During digestion, starches and sugars are broken down both mechanically (e.g. through chewing) and chemically (e.g. by enzymes) into the single units glucose, fructose, and/or galactose, which are absorbed into the blood stream and transported for use as energy throughout the body.

The question bus incomplete, below is the complete question;
You need to determine which degradable material to use as a tissue engineering scaffold for repair of a critical-sized bone defect. (A critical-size defect is one that will not heal unaided.) You are planning to seed the scaffold with cells then implant it into the defect. While the cells proliferate and generate bone, the scaffold will degrade and create void space into which the new tissue may grow. What degradation method would you prefer for this scaffold material and why ?
(Hydrolytic vs Enzymatic degradation, Bulk vs Surface degradation).
The correct answer to the question is Degradation via Hydrolysis.
This Degradation via Hydrolysis will be most preferred and suitable in this application because,as a result of the aqueous environment between the patients, the lack of need for placing a target on the degradation areas (Since it is implanted into the site that has defect, it is accessible by water because it is already localized).
The bulk degradation of the scaffold will also be considered because since the overall dimensions will be consistent, over a given period of time.
But if the material underwent surface degradation, the implant could loosen up before there is sufficient tissue repair has developed or even fall out of the defect..
Or any cells that are seeded can equally detached itself from the scaffold.
What are oligosaccharides used for?
Answer:
Fructo-oligosaccharides are made up of plant sugars linked in chains. They are taken from asparagus, Jerusalem artichokes, and soybeans, or produced in the laboratory.

HeLP PLZZZ. How was the elasticity related to the bounciness of a ball?
Answer:
elasticity is the ability of an object or material to resume its normal shape after being stretched or compressed; stretchiness.
For a ball to bounce, it must be made from materials with high elasticity so that they can maintain their shape instead of absorbing the impact of a toss, by changing shape. The elastic properties reduce the amount of deformity that comes from an impact, making it more effective at bouncing.
Explanation:
The bouncing of a ball mainly depends on two major factors one is the elasticity of the material of the ball and the other the force at which it is bound.
The elasticity is the ability of the material to resisting against distortion or change such as squeezing, stretching, and return to its original form again.
The elasticity is different for the different materials.Ruber is more elastic in comparison to metal, plastic, or marble.The ball bounce if dropped from a particular height due to its elastic property.When the ball hit the surface it squeezed and due to its elasticity, it returns to its original shape and rebound and bounce.Thus, the correct answer is - elasticity leads to an elastic collision and ball bounces.

Part A Why are Northeast Pacific populations of transient and resident killer whales thought to represent different ecotypes rather than different species? View Available Hint(s) Why are Northeast Pacific populations of transient and resident killer whales thought to represent different ecotypes rather than different species? Transient killer whales prey on marine mammals, while resident killer whales prey on Chinook salmon. Transient and resident killer whales learn specific methods of hunting from older whales in their pods. Transient and resident killer whales differ in feeding culture but can mate and produce viable offspring in captivity. Transient and resident killer whales have different patterns of communication.
Answer:
Transient killer whales prey on marine mammals, while resident killer whales prey on Chinook salmon
Explanation:
Remember, the term "ecotypes" is used to refer specifically to the observable differences found in the various kinds of whales, which includes their breeding populations, their language of communication, social structure, the type of food they eat, and their hunting behavior.
Thus, in the case of transient and resident killer whales in the Northeast Pacific, they are thought to represent different ecotypes rather than different species the Transient killer whales prey (feed) on marine mammals, while resident killer whales prey on Chinook salmon. Also, whales are generally thought to belong to the same species.
