Answer:
the plastids
Explanation:
Answer:
The plastids are the organelles that compose the cells of plants and algae. These contain chloroplasts, which allow them to capture energy from sunlight. If they are ever removed, these cells will eventually lose their ability to photosynthesize food without help from another organism - they have lost an essential organelle. Without the presence of this organelle, eukaryotes may not have been able to use sunlight as a mechanism for producing oxygen or making nutrients such as glucose available for consumption.
The organelle that may have allowed early eukaryotes to make food and produce oxygen is the plastid. The correct option is c.
What is plastid?The organelles that make up the cells of plants and algae are called plastids. These have chloroplasts, which enable them to absorb solar energy. These frequently include several kinds of pigments that can alter the color of the cell as well as pigments that are employed in photosynthesis.
These cells will eventually lose their capacity to photosynthesize food without the assistance of another creature if they are ever taken out since they have lost an important organelle.
Eukaryotes might not have been able to exploit sunlight to produce oxygen or make nutrients like glucose available for consumption without the presence of this organelle.
Therefore, the correct option is (c) the plastids.

1. how would dr.budai refer to the new fern that contractors plan on introducing into the environment?
2.how might removing the flowering plants and replace it them with ferns affect the population numbers of the butterfly and the new species?
3. how might the building of the hotel affect the population of the new species?
Growing of ferns instead of flowering plants and building a hotel adversely affect the butterfly and species.
Dr. budai has bad reaction to the new fern that contractors plan on introducing into the environment because it will be grown instead of flowering plants which is necessary for the survival of butterfly.
Removing the flowering plants and replace it them with ferns negatively affect the population of the butterfly and the new species because butterfly feeds on the nectar of the flowers whose removal decrease the population of butterfly and those species which feed on butterfly also adversely affected due to unavailability of food source.
The building of the hotel adversely affect the population of the new species because habitat of that species will be destroyed so we can conclude that growing of ferns instead of flowering plants and building a hotel adversely affect the butterfly and species.

Answer:
Carbohydrates- is the main source of energy of your body. They help you fuel your brain, kidneys, heart muscles, and central nervous system.
Protein- A lot of your body is protein. Your muscles are just about all protein, and most of your organs are protein. Many of the chemical reactions in your body are speeded up by other types of protein. Your body can make some of the components of protein by itself, and it must get some of the components from outside of the body.
You need protein daily for your tissue to repair itself, normal function, and perhaps to grow.
Vitamin- Vitamins allow your body to grow and develop. They also play important roles in bodily functions such as metabolism, immunity and digestion.
