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.
Why are video games so fun? Can any one explain, i'm just so confused
Answer:
I really don't know
Explanation:
Each video game is addictive for different reasons. Also, each person may find different elements of a game addictive. Although every case is unique, there are general patterns that can help explain why video games are addictive.
Video games are addictive because they help meet our basic psychological need for a sense of freedom, purpose/progress, and social connection.
Let’s take a closer look at each of these factors.
Video games offer a sense of freedom
Video games can be addictive because they offer a high degree of freedom that is unparalleled outside gaming environments. Let’s take a look at a few ways video games facilitate a sense of freedom.
Video games allow you to escape from social constraints.
From fantasy science fiction worlds to realistic combat environments, games allow a person to escape from the normal constraints of the offline world. This is especially relevant for someone struggling with social anxiety.
Offline social interaction can be challenging for individuals who find social situations anxiety-provoking, confusing, or over-stimulating. Games offer an escape from the constraints of social anxiety, providing a sense of freedom and control.
Although games serve as a short-term escape, avoiding in-person social situations comes at a long-term cost. Rather than facing one’s fears and dealing with the anxiety, games offer virtual freedom while keeping an individual dependent on the game as a form of escapism. Using games to avoid difficult emotions can lead to increased use over time, making in-person interaction even more difficult.
Video games allow you to experiment with different identities.
By experimenting with one’s personal gaming avatar, games offer the chance to try out new identities instantly, without the long-term social implications of the offline world.
This can be especially engaging for individuals who are dissatisfied with their offline identity, suffer from low self-esteem, or feel they cannot express certain aspects of their identity in their offline social context.
Identity experimentation through games can be healthy and liberating, but it can also be detrimental to developing one’s offline identity and sense of self-esteem. This is especially relevant if games serve as a form of escape or way to avoid confronting deeper self-esteem issues.
Video games offer a sense of adventure.
Games offer the infinite ability to explore new worlds. For those high in novelty-seeking, gaming environments offer a high level of exploration and experimentation without the dangers present in the offline world.
The modern world can often seem mundane, especially if you are bored and dissatisfied in your work or schooling. Gaming environments offer a way out of this monotony of everyday life and can be addictive because of the infinite possibilities they present.
Video games offer a sense of purpose
Video games can be addictive because they offer a strong sense of mission and purpose. Let’s take a closer look at how games offer a sense of purpose.
Video games facilitate a sense of progress through leveling up.
Games offer a sense of progress through their mission orientation. In addition, players gain a sense of mastery when their skills improve. This mission orientation and skill improvement are symbolized by character development, resource acquisition, leveling up to new environments, and various point systems.
This sense of progression can be especially rewarding for someone who feels like they are in a rut in their offline life. Games offer a way to meet our basic need to feel like we are progressing, even if it is virtual.
Another addictive feature common in games is their variable-ratio reward schedule. Like slot machines, games are designed with features that randomly reward players, keeping them hooked on a sense of anticipation. Loot boxes are a common form of this reward structure.
Video games with no defined end encourage infinite play.
Games with no defined endpoint encourage long-term investment. This can be addictive because the more time and energy one invests into an activity, the more difficult it is for them to simply abandon all of their efforts.
In addition, long-term play with a specific avatar builds a sense of identity investment, making it more difficult to let go.
If you took a linear piece of DNA and cut it with the restriction enzyme EcoRI and it had three restriction sites for EcoRI, how many fragments would you produce? What if you had a circular piece of DNA?
Please help! Is somewhat urgent :(
If we took a linear piece of DNA and cut it with the restriction enzyme EcoRI which had three restriction sites for EcoRI, then the resulting number of fragments that it would produce is five (5) fragments in a linear sequence and four (4) fragments in a circular piece.
What is a restriction enzyme?A restriction enzyme is a protein that has a defined catalytic activity that can be used to cut a given sequence of nucleic acids.
In this case, the EcoRI restriction enzyme can be used to cut in a specific nucleotide sequence that contains a given linear order of nucleotides in the cutting site.
Therefore, with this data, we can see that the restriction enzymes are able to cut the nucleic acids in specific sequences such as the EcoRI restriction enzyme that cut at particular nucleotide regions (this enzyme cuts at AATT positions).

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.

I extracted DNA from strawberry. I had to answer: - Why did the DNA separate to the top after adding the isopropyl alcohol? - Does all of your food have DNA? Explain your reasoning. - Why is it important for scientists to be able to extract DNA? Provide two examples.
1. Isopropanol is a compound used to dissolve lipids and as a dehydrating agent. When mixed with DNA, they compete for water causing the DNA to dehydrate and separating the mixture into two phases.
2. Every living organism contains DNA. This includes plants and animals, and therefore most of the food we eat.
3. DNA contains the hereditary information of all living organisms.
For example, in humans it is important to extract DNA for the identification of diseases, their causes and possible treatments.
In food, DNA extraction can help in the production of transgenic foods.

If all planets were the same distance from the sun, which would have the largest gravitational force between itself and the sun? Why?
If all planets were the same mass, which would have the lowest gravitational force between itself and the sun? Why?
Answer: Mercury
Explanation:
Looking at the general equation for gravity attached below we see that radius is indirectly proportional so as it increases the force decreases.
The masses of m1 and m2 are directly proportional so as either of them increases then the gravitational force increases.
In this example the radius and m2 are all the same so the only difference will be the mass of the other planets.
Mercury has the lowest mass of all the planets in the solar system so it will also have the lowest gravitational force between it and the sun in this example.

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
