1.) What could happen if you remove an organism from a food chain?
2.) What is biodiversity?
3.) Why is biodiversity important in an ecosystem?
Answer:
1. every organism on the food chain will be affected. the ones below it will have a higher population, and the ones above it will have a lower population.
2. biodiversity is the idea, that all life is different, and environments thrive with it.
3. biodiversity is important in an ecosystem because if you take out biodiversity, you essentially take out all the animals in the given ecosystem.
Explanation:
1. when you remove lets say a spider from a food chain, the bugs that it would've eaten will start growing in population from not being eaten by the spiders. the birds that wouldve eaten the spiders, will decrease from the lack of that food source.
2. is self explanatory
3. if you only had one type of bird in one ecosystem, and that was the only animal in that ecosystem, the birds would all die, because they wouldn't have anything to eat, and nothing would eat it, so they might resort to cannibalism, or, as earlier stated, they would die off, from lack of food. the ecosystem would not be sustainable.

what are thylakoids? I will give BRAINLIEST!!
Answer:
each of a number of flattened sacs inside a chloroplast, bounded by pigmented membranes on which the light reactions of photosynthesis take place, and arranged in stacks or grana.
Thylakoids are membrane-bound compartments inside chloroplasts and cyanobacteria. They are the site of the light-dependent reactions of photosynthesis. Thylakoids consist of a thylakoid membrane surrounding a thylakoid lumen. Chloroplast thylakoids frequently form stacks of disks referred to as grana.
Explanation:
Answer:
They are membrane-bound compartments inside chloroplasts (the food producers of the cell) and cyanobacteria (group of photosynthetic bacteria).

Answer:B, C and D
Explanation:
A single molecule of some compounds can contain thousands of carbon atoms. Each carbon atom can form single bonds with up to four other carbon atoms. Thus, all of the given statements are true.
What are the properties of carbon atom?Carbon is found in almost all the biomolecules and majority of compounds present in the atmosphere. All the living things contain carbon in the form of different biomolecules. A single molecule of some compounds can contain up to thousands of carbon atoms including polymers which make up the cell wall and cell membrane.
Each carbon atom can form single bonds with up to four other carbon atoms. This is due to the valency of carbon which is four, thus it can form covalent bonds with other atoms or elements. This property of Carbon is known as tetravalency. Carbon has the ability to form long chains when it gets linked with other carbon atoms.
Each carbon atom can form double bonds with up to two other carbon atoms or more.
Therefore, all these statements are true.

Six white-tailed deer and six sika deer were enclosed in a pasture for observation during an eight-year study in central Texas. White-tailed deer are a native species to central Texas, while
sika deer are a nonnative species to central Texas. White-tailed deer feed on flowering plants and the tips of trees and shrubs but do not eat grass. Sika deer feed on flowering plants, the
tips of trees and shrubs, and grass. All other grazing animals were kept out of the pasture during the study. The number of sika deer more than doubled after the eight years, while the
population of white-tailed deer decreased by 50 percent.
Which of the following statements best supports the results from the study?
A
The sika deer are generalists, while the white-tailed deer are specialists.
B
The sika deer out competed the white-tailed deer in consuming flowering plants and shrubs.

Answer:

skin
According to cell theory flowers, blood, bacteria and skin all are made up of cells.
What is cell theory?The cell theory is a scientific theory that was initially developed in the middle of the nineteenth century, which states that all living organisms are composed of cells, that cells are the fundamental structural/organizational unit of all organisms, and that all cells originate from pre-existing cells.
Knowing that all living things are cells helps us comprehend how they are born, grow, and die. That information helps us understand how new life is produced, why creatures take their forms, how cancer spreads, how diseases can be handled, and more. Cells help us grasp life and death: a living creature is alive, while a dead one is dead.
Therefore, flowers, blood, bacteria and skin all are living things made up of cells.
