The low-pressure areas have a relatively thin atmosphere and that causes air to rise fast to make clouds. Sometimes, a storm is formed due to air can't move downward towards the surface and instead, it converges. Severe storms are mostly observed in low-pressure areas because it has perfect conditions: the air is thin, high wind speeds, and rapid spiral movement. Warm ocean waters are catalysts for these storms.

El agua destilada y el agua de chorro son hipotónicas comparadas con la sangre. Si el glóbulo rojo se sumerge en una solución que tiene una osmolaridad menor a 0.32, el agua entra al glóbulo rojo, haciendo que éste se hinche (turgencia) y rompa si el agua que entra es considerable (proceso de hemólisis). ESPERO QUE TE AYUDE :)
When a blood sample is placed in distilled water for two hours. The blood cells gained water because they were placed in a hypotonic solution. Thus, the correct option for this question is B.
What is a Hypotonic solution?A Hypotonic solution may be defined as a type of solution that possesses a lower osmotic pressure than the solution through which it is compared. This type of solution generally has a lower solute concentration.
Distilled water significantly behaves hypotonic to the red blood cells. Due to this, the red blood cells swell, and red-colored pigment known as hemoglobin leaks from it as a cell increases its size. Due to this, the color of the solution changes into transparent red-pink.
Therefore, when a blood sample is placed in distilled water for two hours. The blood cells gained water because they were placed in a hypotonic solution. Thus, the correct option for this question is B.

I need help with this practice problem I answered it, however, I’m struggling with if I am right…
Your answer is right.
First of all organic matter (organisms) sink to the bottom of an ancient ocean and mix with the inorganic. This cretes an organic-rich mud that can only form in still water enviroments. This mud cannot be exposed to too much oxygen.
If this shale is buried some kilometres, its temperature increases due to the location in the Earths interior. This increasing pressure and temperature transforms it into oil.
If the organic material is recycled by microorganisms, this process cannot occur.

Solution:
The correct answer is:
Definition and General Description: Kudzu or -Pueraria montana lobata variety- is a group of perennial vines and climbers. a relative of the pea and native to Japan. the kudzu is listed as one of the hundred most harmful invasive species in the world,
Origin: East Asia, Southeast Asia, and some Pacific islands. This plant is invasive in North America.
Food: autotrophic because the Kudzu is a plant.
Important feature: Kudzu can cause environmental damage as it is an invasive plant. In fact, the environmental and ecological damage of Kudzu results from its competition with other plant species. In particular, kudzu competes with native flora for light and acts to block their access to this vital resource by growing over them and shading them with its leaves. Native plants may die as a result
Explain one environmental drawback, not related to water use, of using the franking process to extract natural gas from shale.
One environmental drawback of using the franking process to extract natural gas from shale, is air pollution.
Methane is a main component of natural gas and is 25 times more potent in trapping heat in the atmosphere than carbon dioxide. A number of other air contaminants are released through the various drilling procedures, including construction and operation of the well site, transport of the materials and equipment, and disposal of the waste. Some of the pollutants released by drilling include: benzene, toluene, xylene and ethyl benzene (BTEX), particulate matter and dust, ground level ozone, or smog, nitrogen oxides, carbon monoxide, formaldehyde and metals contained in diesel fuel combustion---with exposure to these pollutants known to cause short-term illness, cancer, organ damage, nervous system disorders and birth defects or even death .
A normal allele for a gene has more base pairs than the mutated form of the allele. Which type of mutation occurred?
O base pair separation
O base pair insertion
O base pair substitution
O base pair deletion
Answer: Base Pair Deletion
Explanation:
If the normal allele has more than the mutated then that means nucleotides were lost so a deletion occurred.
Answer:Base Pair Deletion
Explanation:
We know this because it is stated that the normal gene has more base pairs than the mutated gene. In other words, the mutated gene has less base pairs than the normal gene, which means that base pairs must have been deleted during the mutation.
why is it important to calculate the diameter of the field when first using the microscope? bboldiitalicsuunderlinebulleted listnumbered listsuperscriptsubscript
You can calculate the real size of small objects with the microscope, so in a field, it is important to calculate the diameter.
What is a microscope?You may determine the actual size of things that are too tiny to be seen with the eye by measuring the microscope's field of view.
The largest useable field diameter in early microscope objectives typically ranged from 18 millimeters or less, but with a contemporary plan, it can occasionally approach 26 millimeters.
A microscope measurement can be used to classify an object into a certain size group or to determine whether the produced form of a specific feature is within dimensional.
Therefore to find the size of the smallest object in the microscope calculates the diameter of the field.

What is the meaning of life?
Answer:
The meaning of life is to positively influence as many of the lives around you as possible.
Explanation:
Some people begin to feel a sense of dread when thinking about how little space they take up, and how long they will be alive, because it seems quite small and meaningless in the grand scheme of things.
That, however, is a result of the human brain rationalizing the value and worth of something by how long it exists and how much space it takes up. In reality, something does not need to take up much space, or exist for very long, in order to be worthy and meaningful.
For instance, a hamster is very small and may live only three years before passing of old age. However, if that hamster made a person happy — filled them with joy every day when they arrived home, gave them a reason to get out of bed even when they didn't feel like it, gave them the feeling of love even while being isolated — then it had a very, very meaningful existence.
Humans are very small, and we exist for very short amounts of time, but we have the power to feel and love and change our surroundings, and as long as we leave behind a legacy of even one smile, or even one life saved (no matter how small - a lizard, perhaps), or even one moment of hope, then we will have fulfilled our purpose, and that is all we could ever ask for.

Which of the following changes takes place during the first trimester of awoman's pregnancy?A. The placenta attaches to the mother and nourishes the growingfetus.B. The fetus begins rhythmic breathing movements.C. The mother feels the fetus move for the first timeD. The fetus develops toenails, lips, and eyelashes.
We know as the first trimester of the pregnancy the period from conception to the 12 weeks of pregnancy.
Around 24 hours after the fertilization, the zygote becomes a blastocyst, which implants into the uterine wall. Then it becomes an embryo and during this stage, the placenta and umbilical cord are also formed.
The embryo becomes a fetus around 8 weeks after conception, and by this stage, fingers, eyes, mouth, and ears begin to be recognizable.
Of the options, the one which better aligns with the events of the first trimester is A. The placenta attaches to the mother and nourished the growing fetus.

Discuss the excretory system and circulatory system and how they maintain homeostasis through feedback.
Regulating the body temperature happens through the process of thermoregulation. One system that is responsible for this is the excretory system. This process is an example of negative feedback. The body temperature tends to fluctuate within a normal range. So, the brain's control system and other parts of the body monitor this fluctuation and react to deviations from homeostasis.
The circulatory system is composed of blood vessels, including arteries, veins, and capillaries that are capable of dilation and constriction in order to help the body maintain its homeostasis. This system is also an example of negative feedback
Two life functions performed by all living organisms are nutrition and respiration.
Identify two other life functions that are essential for the survival of all living organisms.
Explain how each of the two life functions you identified maintains homeostasis. Life function 1:
Life function 2:
Life processes are the fundamental tasks carried out by living things to maintain their own existence. Apart from nutrition and respiratIon other live functions performed by living things include; Excretion and MOVEMENT
Relationship between life functions and homeostasis
Homeostasis is a self-regulating process that controls internal factors needed to maintain life. In other terms, homeostasis is a system that maintains a constant environment inside an organism despite changes in the outside.
Excretion
All living things produce poisonous materials as a result of various metabolic processes. These wastes are eliminated from the body by excretion. Animals mostly create carbon dioxide and nitrogenous wastes as waste products (ammonia, urea, uric acid).
In order to maintain internal stability waste Produced by cellular metabolism are excreted
MOVEMENT
Mammals, fish, amphibians, birds, advanced invertebrates, and reptiles (excluding snakes) have organs for locomotion. Animals move around in order to find food, avoid predators, and survive unfavorable environmental conditions.
Joints and muscle contractions allow animals to move their body parts
Some organisms, like the tentacles of a sea anemone, are fixed in position but can move their individual sections.
Plants use their roots to cling to the soil.
DURING MOVEMENT living thing especially animals make use of the Nervous System to carry out homeostasis such as the Cranial nerves, spinal nerve which helps to transport sensory data from the CNS to motor impulses, the Cerebrum which helps to maintain consciousness, creativity, thinking, morals, and memory, Mindfulness, originality, ideas,
In conclusion living thing need to be stable while carrying out life function, other functions include, sensitivity ,growth, reproduction

Explain at the chemical level why plants die when they are not watered.
Your answer must explain the importance of water to photosynthesis and
describe specifically how photosynthesis would be affected and
effectively shut down with the loss of water.
Answer:
All living things need to water to survive. This is because all living things are mostly made of water and since they lose water in different ways, they need to get more water to stay the same size. So if a plant does not get enough water, it will shrink. If it goes long enough without water it will die because the plant uses water for a lot of different jobs needed to keep the plant alive.
