PLEASE HELP MEEEEE!!!!!!!!!!!!!! If 1 kg of fuel is used in the above fusion reaction, the resulting helium has a mass of 0.993 kg. In other words, 0.007 kg of mass is converted to energy. How much energy is produced by the fusion of 1 kg of hydrogen? (Hint: Use Einstein's equation, E = mc2, where E is energy in Joules, m is mass in kilograms, and c is the speed of light, 3 x 108 m/s.) (10 points)
Answer:
mass using E= mc^2 is = 0.007*(3E8)^2 = 6.3E14 Joules

After cytokinesis, how many cells have been formed from the parent cell?
Answer:
The cell now undergoes a process called cytokinesis that divides the cytoplasm of the original cell into two daughter cells. Each daughter cell is haploid and has only one set of chromosomes, or half the total number of chromosomes of the original cell.
Explanation:
The phragmoplast, a structure made up of membranes, actin filaments, and microtubules, controls the deposition of the new wall.
What is the role of cytokinesis in plant cell?Higher plant cells have a unique process for cytokinesis, in which the division of a new cell wall partitions the cytoplasm.
Inside the cell is the cell plate. The location of a preprophase band of microtubules and actin filaments determines where the cell plate is located.
After mitosis, a new cell wall must be created and inserted in plant cells during a process known as cytokinesis.
The cytoplasm of the parent cell is now divided into two daughter cells by a process known as cytokinesis in the cell.
Therefore, each daughter cell is haploid and has just one set of chromosomes, or half as many as the original cell.

When the neurotransmitter GABA binds to its receptor's which way does CI chloride move in what is the consequences of GABA binding
Answer: Cl moves in; GABA is inhibitory
Explanation:
For a neuron to fire, it has to reach what is called a 'threshold' that is more positive than the resting membrane potential. When GABA binds, Cl- flows inside the neuron and hyperpolarizes the membrane, AKA making it more negative. That means when the neuron wants to reach the threshold, it has to make an even bigger jump from its negative state to the more positive threshold. This inhibits the neuron.
