Answer: 1. Maury digs a hole in the ground with a shovel and plants a sunflower seed.
2. In time, the sunflower draws water and nutrients from the soil and releases water vapor into the air through its leaves.
3. The air also brings rainwater to the soil.
Geosphere refers to the crust and upper mental part of the earth. It represents the solid part of the earth. The following sentences in the passage directly involve the geosphere.
Maury digs a hole in the ground with a shovel and plants a sunflower seed.: Here, the ground is the part of the geosphere being impacted by the shovel to dig a hole.
In time, the sunflower draws water and nutrients from the soil and releases water vapor into the air through its leaves.: Here, the water present in the geosphere is being taken up by plants. Therefore, this sentence involves geosphere.
The air also brings rainwater to the soil. : Here, the water being evaporated from geosphere comes back in the form rain to the geosphere.
Answer:
A
Explanation:
Usually a virus is mainly made up of genetic material (DNA or RNA) inside a capsid/envelope. It has no organelles like a ‘true’ cell. Because it cannot reproduce on its own, scientists struggle to categorize it as a living thing since reproduction is a property of living things. The virus reproduces by hijacking the cellular mechanisms of the host cells to replicate itself. It does so by integrating itself in the genome of the host so that its DNA is also replicated, along with that of the host, by the host cell DNA polymerases and its proteins produced by the ribosomes of the host.
Answer:
Glutamate Hippocampus, Frontal lobe, Sympathetic nervous system Cerebellum and GABA increases the performance during exam.
Explanation:
Glutamate, Hippocampus and Frontal lobe are the factors which help him in the preparation for successfully taking the exam because all these factors are linked to memory and we know that good memory gives good results in the examination. Sympathetic nervous system, Cerebellum and gamma-Aminobutyric acid (GABA) have a great impact on the Jackson's performance on the day of the exam because Sympathetic nervous system sends extra blood to the muscles when there is stressful situation while Cerebellum helps in the coordination of the muscles i. e. helps in movement of muscles such as for writing. Gamma-Aminobutyric acid (GABA) is eaten orally due to relieving the anxiety during stressful condition.
