Adding more solute will increase the solute potential and decrease water potential by making it more negative.
Explanation:
Prior to the industrial revolution, what was the previous highest level of co2 concentration in the atmosphere over the prior 400,000 years?.
The previous highest level of CO2 concentration in the atmosphere over the preceding 400,000 years was 300 PPM prior to the industrial revolution.
Fossil fuel burning for transportation and electrical generation, cement manufacturing, deforestation, agriculture, and numerous other practices all contribute to CO2 pollution. CO2 and other greenhouse gases trap heat from the planet's surface that would otherwise escape into space. This causes the planet's atmosphere to warm steadily, triggering a series of weather effects like extreme heat, drought, and wildfires, as well as more precipitation, flooding, and tropical storms.
Prior to the industrial revolution, CO2 levels were reliably around 300 PPM for just about 400,000 years earlier of human civilization. Since then, approximately 1.5 trillion tons of CO2 pollution have been produced by humans, much of which will continue to warm the atmosphere for thousands of years.

The complimentary base strands for TGA CAA CGA GGT ACT are
Chargaff's rule, also known as the complementary base pairing rule, states that DNA base pairs are always adenine with thymine (A-T) and cytosine with guanine (C-G). A purine always pairs with a pyrimidine and vice versa. However, A doesn't pair with C, despite that being a purine and a pyrimidine.
Explanation:Complementary base pairs refer to the nitrogenous bases adenine, thymine, cytosine, and guanine. in a double strand of DNA, adenine will always pair with its complement thymine and cytosine will always pair with its complement guanine. This means that the two strands are complementary to each other. For example, a strand of DNA with a nucleotide sequence of AGTCATGA will have a complementary strand with the sequence TCAGTACT.

b) Food needs to be absorbed into the blood in order for it to be carried into the cells through the blood and for this it needs to be soluble into the blood otherwise the cells will not get nutrition. Digestive enzymes breakdown the food into very small soluble form so that they are easily soluble in the blood
2.a) It accurately depicts the breakdown of a large object into smaller pieces
b) There are different enzymes for different substances. One enzyme cannot breakdown all substances like one scissor can cut different shapes.
Extra info: The substances broken down by enzymes are called substrates. If the shape of the substrate does not match with the active site (where the breakdown occurs) of the enzyme, the enzyme will not affect it at all.
3.a) The model clearly depicts that the enzymes need to match with the substrates like keys to a lock for it to affect the substrate. the mouth of the spanner is like the active site of the enzyme. It only works when the shape of the nuts matches with it.
b) It shows that the substance itself is not broken down but pieces of the substance is taken apart which enzymes do not do. Enzymes breaks down a substance completely into smaller parts.

What is the amygdala's primary function?
The amygdala is typically believed to be the central component of a brain system for processing scary and frightful stimuli, including threat recognition and activation of appropriate fear-related responses in response to dangerous or threatening stimuli The amygdala is in charge of handling intense emotions like fear, pleasure, or rage.Additionally, it might communicate with the cerebral cortex, which governs conscious thought.Physical reactions are governed by signals that are delivered from the thalamus to the skeletal muscles and autonomic nervous systemThe amygdala is crucial in the development of anxiety reactions to upsetting and stressful circumstances.The basolateral, central, and medial subdivisions of the amygdala have undergone pharmacological and lesion studies, which have revealed that their activation results in anxiogenic effects whereas their suppression results in anxiolytic benefits. But these days, you're more likely to come across psychological dangers like the strains and stresses of contemporary life, job, and relationships.These feelings can also set off the fight-or-flight response in the amygdala.Stress, fear, anger, and violence are frequently encountered emotional triggers. Amygdala stimulation results in strong emotions like fear or anger.The amygdala is stimulated by irritable lesions of temporal lobe epilepsy. Researchers have shown that amygdala injuries can lead to hypervigilance in reaction to others' perceived dread.In other words, a person who has amygdala injury develops a heightened sensitivity to even the smallest of facial expressions and interprets them as potential threats. Because anger is simpler to feel, it can keep you from acknowledging and addressing the inside suffering.Frustration is one of the main emotions that tends to start people off.It's common to feel frustrated when you're powerless or uncontrollable.
