Answer:
Plant cell
Explanation:
Cell wall: cell wall is only found in plant cell . it is made up of cellulose. it's function is to give shape to the cell and protect the delicate inner parts of the cell. this cell is fully permeable. it means it will allow all substance to pass in. cell membrane is made up of protein and lipids. it's function is to control what comes in and out of the cell. this membrane is selectively permeable. it means it allows some substance to pass in and others don't. cytoplasm is large sac like structure. most chemical process occur here. chromoplast are the green pigments.
cell wall is only found in plant cell . it is absent In animal cell . the neucleus in the plant cell contain a pigments haemoglobin, which contain genetic information to the cell .
Answer: 3- mutation, natural selection, migration
Explanation:
1-genetic drift, mutation, natural selection
2-mutation, founder principle, bottleneck effect
3-mutation, natural selection, migration (gene flow)
The correct answer for this question is" #3.mutation, natural selection, migration (gene flow)." The sequence of evolutionary mechanisms which have come into effect in each event is that of mutation, natural selection and migration. There is a steady rise in the population of bright-colored fish. Both populations thrive.
Mitochondria - The mitochondria is referred to as the power house of the cell. Its main function if to produceenergy for cell by the process of cellular respiration. The energyproduced is ATP. Endoplasmic Reticulum - It is a network for transportation of certain substances in and out of the nucleus.
Answer:
The correct answer is - water pollution.
Explanation:
In the US, water pollution is one of the most serious ecological problems, and sedimentation by filled with dirt, slit caused by development sites or construction sites. It is caused in the name of developing cities and states for new homes and other construction that is nothing but careless development that is causing water pollution in these areas including the Virginia.
The excessive silt has covered the spawning beds of fish causes spawning of the habitat. The dirt and slit and sediments cause inhibiting light to aquatic plants that result in less oxygen and food for aqautic life.
The photosynthesis reaction(s) (by green plants in sunlight)
6 C02 + 6 H20 =>C6H1206 + 6 02
