Chemicals known as ____ and ____ guide neuron.
Answer In contrast, neurons in many regions, including the cerebral cortex, cerebellum, hippocampus, and spinal cord, are guided to their final destinations by crawling along a particular type of glial cell, called radial glia, which acts as a cellular guide

A woman, Penelope, has a sister with polycystic kidney disease (ARPKD), which is inherited in an autosomal recessive mode. Penelope does not have the disease, and both of her parents do not have ARPKD. Penelope marries a man from Europe who does not have ARPKD. There is no information about whether this disease runs in his family, but 96% of the population does not have ARPKD (assume the disease is in Hardy-Weinberg equilibrium). What is the probability that they will have a child with ARPKD? A) 0.25 B) 0.15 C) 0.05 D) 0.04 E) there is not enough information to answer this question
Suppose Sally grew a wild type E. coli culture in rich liquid media that contained all 20 amino acids until the culture was dividing exponentially, with one cell division approximately every 20 minutes. She then added the mutagen 5-bromouracil to the media. After the cells had grown for 20 more minutes, she washed the cells to remove the mutagen and resuspended the washed cells in sterile water. Next, Sally plated the resuspended cells on minimal media supplemented with tryptophan and obtained well-separated colonies, such that each colony arose from a single bacterial cell. She replica-plated these colonies on minimal media and selected a single colony that grew on the media supplemented with tryptophan, but not on minimal media. Sally inoculated 10 test tubes containing fresh minimal media supplemented with tryptophan with cells from this colony and grew the 10 cultures until the cells were dividing exponentially. She then plated 0.1 mL of each culture onto separate plates containing minimal media. No colonies grew on 3 of the 10 plates. Colonies grew on the remaining seven plates, with one plate containing about 100 colonies and the other plates each containing between 1 and 15 colonies. What type of mutation allowed colonies to grow on these seven plates? a) spontaneous forward mutation b) spontaneous reverse mutation c) induced forward mutation d) induced reverse mutation

Answer:
Rainfall and temperature can affect the rate in which rocks weather. High temperatures and greater rainfall increase the rate of chemical weathering. ... Minerals in a rock buried in soil will therefore break down more rapidly than minerals in a rock that is exposed to air.

B.) Solids have more energy than plasma
C.) Solids have the most amount of energy
D.) Solids have the least amount of energy
Answers
Answer:
The answer is D.) Solids have the least amount of energy
Explanation:
Because in a solid, particles are packed tightly together so they don't move much. The electrons of each atom are constantly in motion, so the atoms have a small vibration, but they are fixed in their position. Because of this, particles in a solid have very low kinetic energy.
Final answer:
Solids have the least amount of energy among the four physical states of matter because their particles are held tightly together and can only vibrate, possessing less thermal energy than in the liquid, gas, or plasma states.(Option D)
Explanation:
The correct statement about the energy level of solids is that solids have the least amount of energy among the four physical states of matter. In a solid, the atoms or molecules are held close together by strong intermolecular forces, which significantly restricts their ability to move. As a result, the particles can only vibrate about fixed positions, and this vibrational motion accounts for the thermal energy in solids.
This is less energy than the particles have in liquid, where they can move freely but are still close together, and much less than in gas, where the particles have enough energy to break away from one another and fill the available space. In plasma, which is an ionized state with even higher energy, particles have the most energy compared to the other states of matter.

Answer:
Tetany
Explanation
The refractory period in the heart refers to the shortest interval between consecutive contraction conducted impulses out of the cardiac muscle.
It is important because it allows adjustments to stimuli and limits amount of action potential sent per minute.
Without a plateau extending the refractory period in the cardiac muscles.
Sarcomeres might be stimulated to contract instead of relaxing leading to sustained contraction also called Tetany.
Tetany is an involuntary muscle cramp or contraction caused by overly stimulated nerves.

The way that reduced precipitation can lead to limited water availability is as follows: It may lead to drought (option D).
What is precipitation?
Precipitation is any or all of the forms of water particles, whether liquid or solid, that fall from the upper atmosphere. Examples are rain, snow etc.
Precipitation is one of the major supplies of water to the Earth, hence, a reduction in the amount of precipitation (rainfall) will adversely affect the availability of water by causing drought, which is a period of unusually low rainfall.
Therefore, it can be said that the way that reduced precipitation can lead to limited water availability is as follows: It may lead to drought.
