It is the first option. Atmospheric nitrogen is very stable so there fore hard to react with. But bacteria contain molecules that can break the bond of nitrogen.
Answer:
The movement of proteins and enzymes within a cell is facilitated by intracellular receptors.
Explanation:
Proteins and enzymes (which also are proteins) move inside the cell through intracellular receptors. These receptors are proteins capable of binding other molecules such as proteins and hormones in order to transport them to different cellular locations. Thus, intracellular receptors are key players in signaling pathways that trigger signaling events to regulate a particular function, for example, activating gene expression by transporting proteins to the nucleus.
First of all, the most common type of CNS neuron is the multipolar neuron meaning it has many dendrites and dendritic branches, a cell body or soma, and a single axon. The information flow through this neurons starting from receiving multiple impulses from multiple synapses since this kind of neurons has many dendrites. The signal will then flow in an anterograde manner meaning the multiple signals will flow towards the cell body or the soma to be integrated. Next is that the integrated signal will flow to the neuron's axon to be transmitted to other neurons.
Answer:
Red blood.
Explanation:
Red blood is for oxygenated blood, while blue blood is for deoxygenated blood.
The blood in Isabelle's left ventricle would be red, in other words, oxygenated. The left ventricle has oxygenated blood because this blood was first in the right ventricle. Then, it went to the pulmonary arteries, which led the blood to the capillaries close to the alveoli in the lungs. In this area, the deoxygenated blood dropped the CO₂ and took O₂ becoming oxygenated blood. Now, this blood is color-coded red and will go to the pulmonary venules, then to the pulmonary vein, and from there, it will go to the left atrium. Lastly, it will go to the left ventricle to start the systemic circulation, which is the one that distributes the oxygenated blood in the body.
Answer:
Lividity
Explanation:
This makes the most sense to me.
Good Luck!
