Which of the following statements about enzymes is false?
А Enzymes are made up of amino acids.
B Enzymes make otherwise slow reactions proceed more quickly.
C Enzymes provide energy for endergonic reactions.
D. Enzymes are usually specific for the chemical reactions they catalyze.
The false statement about enzyme is - option C. Enzymes provide energy for endergonic reactions.
Enzymes are protein acts as biological catalysts. Enzymes increase the rate of reactions by lowering the activation energy.
Enzymes are made from amino acids. The chain of amino acids then folds into a unique shape.These are specific for the chemical reactionsEnzymes are biological catalysts that increase the rate of chemical reactions inside cells by lowering the activation energy therefore can not provide energy.Enzymes make slow reactions proceed more quickly.Thus, the false statement is - option C.

When a patient comes to a hospital with severe dehydration, doctors will give
them an IV filled with a salt-water solution called saline, which is isotonic with
the body's blood cells.
Why is the patient not given pure water?
Answer:
The red blood cells could burst.
Explanation:
If they are given pure water, the IV fluid will be hypotonic to the blood cells. That means water will end the red blood cells by osmosis, from a high concentration outside to a lower concentration inside.
This will result in the red blood cells becoming swollen and even potential bursting.

Describe what happens in your central nervous system when you prepare and eat breakfast. Start with objects in the environment and be specific.
Answer:
CNS controls eating by homeostatic mechanisms that interact with different cognitive control systems (e.g., memory, reward, attention, etc)
Explanation:
In the brain, eating control is modulated by different systems:
1- Homeostatic control: the hypothalamus plays a key role by controlling both the appetite and food intake
2- Attention: the parietal and visual parietal cortices are involved in sensory perception and integration
3- Emotion and memory: amygdala and hippocampus
4-Cognitive control: the prefrontal cortex (i.e., executive functions)
5-Reward: associated with the functioning of the striatum
In the first place, external signals such as, for example, neurotransmitters and hormones, are received by the hypothalamus that interacts with different systems (reward, emotion, memory) in order to achieve a homeostatic control of eating. Neuronal stimulation (for example, when we view foods), is achieved by the supply of oxygenated hemoglobin.

PLS ANSWER FAST! Which of these descriptions best contrasts safety knowledge for cows and horses? Horses have a definite flight zone, whereas cows do not Cows will startle at sudden movement or noise. but horses do not. Cows have 360-degree vision, but horses do not Cows have a definite flight zone, whereas horses do not.
Answer:
the descriptions best contrasts safety knowledge for cows and horses is the description that says "Cows have 360-degree vision, but horses do not Cows have a definite flight zone, whereas horses do not"
Explanation:
For horses, the size of the flight zone depends primarily on the tameness or familiarity of the horse with the handler. With frequent handling, the flight zone decreases in size and may even disappear. A horse that is approached head-on has a larger flight zone than if it is approached from the side.
When moving groups of cattle in open spaces. The flight zone is the animal's personal space, and the size of the flight zone is determined by the wildness or tameness of the animal. Completely tame animals have no flight zone and people can touch them.

You add and heat up the water and you dump your ramen in the pot. You let the ramen noodles cook in the water for 5 minutes. As your are straining your ramen noodles, you notice the noodles are larger and there is less water in the pot. Explain what process just happened and why. How does this relate to the process of
cell?
Answer:
Osmosis.
Explanation:
Osmosis occurs in the noodles because the water moves inside the noodles which make them swells. Osmosis is a process in which particles moves from the external environment into the cell through a semi permeable membrane. The water present goes inside the noodle and the noodles increases in size just like cells when the water moves inside the cell it swells due high concentration of water.

DNA libraries are useful for identifying and isolating eukaryotic DNA fragments of interest in research. Select the ways in which genomic and cDNA libraries differ.
a. Genomic libraries are difficult to express in prokaryotic cells, which lack a splicing mechanism.
b. cDNA libraries contain only the sequences from genes that are expressed in an organism.
c. cDNA libraries are the DNA fragment collections that are stored and propagated in host cells through cloning.
d. cDNA libraries contain more sequence information than genomic libraries.
The ways in which genomic and cDNA libraries differ is that the Genomic libraries are difficult to express in prokaryotic cells, which lack a splicing mechanism. Thus, the correct option for this question is A.
What do you mean by Genomic libraries?Genomic libraries may be defined as a group of overlapping segments of genomic DNA that is significantly cloned into a backbone vector, which statistically includes all regions of the genome of an organism efficiently in order to function normally.
On contrary, cDNA libraries may be characterized as the collection of cloned DNA sequences that are complementary to the mRNA and were remarkably extracted from an organism or tissue in order to stimulate its function.
Therefore, genomic libraries are difficult to express in prokaryotic cells, which lack a splicing mechanism is one of the ways in which genomic and cDNA libraries differ.
