How does the suns energy cause a hurricane to form

Answers

The sun heats the land and oceans unevenly, creating areas of upwards and downwards moving air as well as pressure differences. This causes air to flow from one area to another. For hurricanes the sun heats the ocean, causing some water to evaporate. The water vapor powers convection in storms which can then strengthen and organize to form hurricanes. Hope this helps:)

Please help! What is the structure labeled with the question mark?
a. Motor neuron with synaptic terminal
b. Synaptic vesicle with neurotransmitter
c. Receptor protein with action potential
d. Motor end plate with deactivation enzyme

Answers

Ans.

The given diagram represent chemical synapse, which is defined as biological junction between two neurons and is responsible for the exchange of neural signals. The structure labeled with question mark is synaptic vesicle. The synaptic vesicles are small sac like structures that contain neurotransmitters. These neurotransmitters are released by these vesicles through expcytosis and bind to receptors present in another neuron.

Which statement describes one difference between mitosis and meiosis in animal cells? mitosis produces sex cells and meiosis produces diploid cells
mitosis produces haploid cells in meiosis produces somatic cells
mitosis produces two daughter cells in meiosis produces four daughter cells
mitosis produces four daughter cells in meiosis produces two diploid cells

Answers

Answer:

Mitosis produces two daughter cells and meiosis produces four daughter cells

Explanation:

In mitosis, you start off with one parent cell, and it duplicates itself, so as you could see, you would have the original cell as well as the duplicated version, which is a total of 2. In meiosis, there are two main phases, Meiosis I and Meiosis II. The first phase produces two cells and the second phase takes those two cells to form four daughter cells / gametes
