Why are hydrogen bonding and popularity so important for water molecules?
Answer:
they are so important because the presence of hydrogen bonds also makes water molecules more 'sticky' or in scientific terms cohesive and adhesive. The small charges on the water molecules allows them to stick together which is why water has a 'skin' that small insects can walk on, and also explains why water can be sucked up a straw so easily.

Explanation:
Root hair cells
Plants absorb water from the soil by osmosis. They absorb mineral ions by active transport, against the concentration gradient. Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption
Read the excerpt from "The Lady Maid's Bell." I had been near a week at Brympton before I saw my master. Word came that he was arriving one afternoon, and a change passed over the whole household. It was plain that nobody loved him below stairs. Mrs. Blinder took uncommon care with the dinner that night, but she snapped at the kitchen-maid in a way quite unusual with her; and Mr. Wace, the butler, a serious, slow-spoken man, went about his duties as if he'd been getting ready for a funeral. He was a great Bible-reader, Mr. Wace was, and had a beautiful assortment of texts at his command; but that day he used such dreadful language that I was about to leave the table, when he assured me it was all out of Isaiah; and I noticed that whenever the master came Mr. Wace took to the prophets. Which best describes a gothic element in the excerpt and the social attitude it reveals? The arrival of Mr. Brympton causes fear, revealing that men are powerful in the world. Mrs. Blinder prepares a dinner well, revealing that cooking is considered the highest art. Mr. Wace reads the Bible, revealing that religion is no longer a respected institution. The servants do not like the master, revealing that having servants is no longer acceptable.
Answer:
A.) The arrival of Mr.Brympton causes fear,revealing that men are powerful in the world.
Explanation:
This is because after he arrives, the slaves hate him. However, the fact that Mr. Wallace reads a bible doesn't matter because he is more worried that his master is back same with the cook. Therefore, it would be that this particular man is very powerful and has power over these people.

One way scientists can analyze and interpret data to identify potential environmental factors is by
Answer:
Environmental factors include factors in the surroundings that can have an impact on humans. This includes climate, temperature, population density, pollutants, etc.
Explanation:
A way that scientists can analyze and interpret data to identify the potential environmental factors is by analyzing the distribution or variation in traits across a population.
Across a population, environmental factors might play a role with regards to any of the factors including distribution by allowing for variations to occur in these traits.
These variations can then be studied and analyzed.
The other options are determined by genetic factors.

The concentration of lactic acid in the student's
muscle tissue was most likely greatest during trial
A) A В) В
C) C D) D
Option D has the highest concentration of lactic acid in the student's muscle tissue.
We can arrive at this answer because:
Lactic acid increases its concentrations in the muscle due to a high physical effort in anaerobic conditions.This promotes a lack of oxygenation in the muscle, which through contractions, causes the cell to partially catabolize glucose molecules.The result of this is the creation of two pyruvic acid molecules, which will react with NADH2 molecules, creating lactic acid, which will build up in the muscle as the exercise continues.As we can see in the information presented above, option D shows the performance of flexions with more intensity and for a longer period, which justifies a greater accumulation of lactic acid in the muscle.
It is important to remember that the accumulation of lactic acid in the muscle is a negative situation and that it can cause muscle pain and fatigue.

How do coral reefs help with climate stability?
They need vast amounts of carbon dioxide for energy.
They support mangroves and seagrasses that release carbon.
They are habitats for species that build exoskeletons from carbon.
They release atmospheric carbon that organisms use to live and grow.
The coral reefs help with climate stability because they serve as homes for species that build exoskeletons from carbon.
Carbon in the form of carbon dioxide has been reported to be a major factor in the climate instability of the planet. This is because they are parts of the greenhouse gases that form a blanket layer over the atmosphere and prevent reflected sun rays from escaping back to space.
Thus, greenhouse gases cause the earth's atmosphere to warm up, a phenomenon known as global warming. The warming, in turn, leads to the unpredictability of several climatic factors.
With the majority of the species living in coral reefs helping to make use of carbon dioxide to build their exoskeleton, they are helping to reduce the concentration of the gas in the atmosphere and thereby reducing warming and erratic climatic changes.

the genetic code is read in groups of three nucleotide bases known as
Genetic codes are sets of three nucleotides that specify an amino acid. The three-nucleotide base read in the group is known as a codon.
What is a codon?A codon is a set of three nucleotides that codes for the genetic code of the deoxyribonucleic or the ribonucleic acid. The information in it is translated into proteins.
A codon also codes for the stop and start signal of the translation sequence. Each codon codes for particular amino acids and results in the formation of the proteins for cellular function and activity.
Therefore, the genetic code in a set of three is called a codon.

Which best describes chromosomal dilatation
Answer:Changes that affect the structure of chromosomes can cause problems with growth, development, and function of the body's systems. These changes can affect many genes along the chromosome and disrupt the proteins made from those genes.
Structural changes can occur during the formation of egg or sperm cells, in early fetal development, or in any cell after birth. Pieces of DNA can be rearranged within one chromosome or transferred between two or more chromosomes. The effects of structural changes depend on their size and location, whether gene function is interrupted, and whether any genetic material is gained or lost. Some changes cause health problems, while others may have no effect on a person's health.

a. Summarize what it says.
b. How should it help with the problem of acid rain?
c. How successful has it been in reducing the harmful chemicals from the burning of fossil fuels that cause acid rain?
d. What can you do personally to help alleviate the problem of acid rain?
3. Find two examples of actual ecological places that have been affected by acid rain. Tell their location and describe what happened.
Acid rain is formed when gases such as SOx and NOx are released by burning fossil fuels.
The clean air act has to do with the reduction of the gases that lead to acid rain such as SOx and NOx. The full implementation of the legislation ought to reduce the occurrence of acid rain.
However, since the introduction of the act in 1990, reduction in acid gas pollution has not reduced significantly since acid gases are still produced by the burning of fossil fuels.
To help alleviate the problem of acid rain, I must reduce my use of gasoline powered vehicles and embrace vehicles that depend on renewable energy sources and clean fuels such as hydrogen fuel.

drag the labels to their appropriate locations on the diagram of the neurons below. use targets of group 1 to indicate the components of neurons. use targets of group 2 to indicate the locations of gated ion channels.
Neurons are cells in chauge of synapsis. a)cell body / b)myelin sheath / c)synaptic terminal / d)axon hillock / e)nucleus / f)location of voltage-gated channels / g)location of ligans-gated channels / h)axon / i)dendrite
-------------------------------
Most neurons are composed of a cell body, dendrites that are cytoplasmic extensions that receive impulses from other cells, and an axon that is a long formation capable of conducting the electrochemical signals.
Neurons transmit nervous impulses.
Every neuron forms connections with other neurons. These connections are known as synapsis.
During synapsis, when a presynaptic neuron sends information, it releases neurotransmitters. This event is done through exocytosis.
The neurotransmitter is a molecule that travels through the synaptic space forward to the other neuron.
Once it reaches the target, it binds to its receptors in the postsynaptic membrane, causing ion channels to open.
This binding produces a depolarization of the cell called an excitatory postsynaptic potential.
Once the action potential is initiated, it spreads to the rest of the membrane, depolarizing it.
When the electrical stimulus is applied to the axon's membrane, it produces depolarization by activating the sodium voltage-dependent channels all along the axon.
Besides, there is an increase in sodium permeability.
Depolarization propagates to inactivated regions adjacent to the membrane opening more sodium channels.
The fiber diameter and the conduction velocity are closely related, exhibiting a directly proportional relationship. Mielinized fibers are thick, and their conduction velocities are very fast.
The conduction velocity sharply increases in myelinated fibers. This is because of the high concentrations of sodium channels in the Ranvier nodes that are not myelinated areas, and the diameter of the axon becomes thinner.

Can someone explain to me what flowering time is?? And how to control flowering time???
Answer:
Flowering time refers to the amount of time the plants will spend in the flowering stage. It begins when you switch your lights to a 12/12 schedule and ends when the buds are ready to harvest. ... In this case, the actual flowering time (as understood by most breeders) would be 2-3 weeks longer. so the flowers will spend time in differents parts of different stages
A dramatic change in the life cycle of plants is the transition to flowering, which is triggered by both environmental signals, as temperature and photoperiod, and endogenous stimuli. so it would just 2 be to watch over there environment and what u are doing 2 them
Explanation:
Answer:
Flowering time is the amount of time that a plant will stay in it's flowering stage. the flowering time of its life will reach 12 hours or less of light per day.
It's controlled by environmental conditions and development regulations, such as temperature, photoperiod and endogenous stimuli
