Which of the following pairs of base sequences could form a short stretch of a normal double helix of DNA?
A) 5'-purine-pyrimidine-purine-pyrimidine-3' with 3'-purine-pyrimidine-purine-pyrimidine-5'
B) 5'-AGCT-3' with 5'-TCGA-3'
C) 5'-GCGC-3' with 5'-TATA-3'
D) 5'-ATGC-3' with 5'-GCAT-3'
E) All of these pairs are correct.
The pairs of base sequences could form a short stretch of a normal double helix of DNA is:
D) 5'-ATGC-3' with 5'-GCAT-3'
In DNA, the code letters are A, T, G, and C, which stand for the chemical substances adenine, thymine, guanine, and cytosine, respectively. Under normal occasions, the nitrogen-containing bases adenine (A) and thymine (T) pair collectively, and cytosine (C) and guanine (G) pair collectively. The binding of those base pairs forms the structure of DNA.
Because of the base pairing, the DNA strands are complementary to each different, run in opposite guidelines, and are referred to as antiparallel strands.
Complementary base pairing is important in DNA because it lets the base pairs be arranged in the maximum energetically favorable way; it's miles crucial in forming the helical structure of DNA. it's also critical in replication as it allows semiconservative replication.
You could determine the sequence of a complementary strand if you are given the series of the template strand. These strands are complementary, with each base in one sticking to its partner on the alternative. The A-T pairs are linked by means of two hydrogen bonds, whilst the G-C pairs are connected through three hydrogen bonds.

to answer the question, we will discuss each item:
A) The results obtained during an investigation are information that can be used to design subsequent experiments that will answer questions that could not be answered in the first experiment.
B) The activity of making a prediction before performing an experiment is called hypothesis, which is based on observations. That is, first we will observe the phenomenon, and based on our reasoning we will generate a prediction or hypothesis that we will test with an experiment to see if it is correct.
C) An important part of the research is to have detailed records of each part of the experiment, this way if there is an error we can know in which part of the experiment it occurred and also we can give this information to other researchers so that they can replicate the experiment and confirm the results we obtained.
D) Finally, when the experiment is finished and when we are analyzing the information, we must take all the data into account and not only those that confirm our hypothesis, since that would give us an erroneous conclusion and would be a bias of information. Therefore, the answer is D.

Is resource availability the onlyfactor affecting carrying capacity?A. Yes, resources are the only factor affectingcarrying capacity.B. No, changing seasons and disease also affectcarrying capacity.C. No, predation and omnivore activity affectcarrying capacity.
Let's first define what carrying capacity is:
Carrying capacity is the maximum amount of organisms an ecosystem can carry. It is related to our logistical growth formula:
[tex]\frac{dN}{dt}=r_{max}(\frac{K-N}{K})N[/tex]Where K is our carrying capacity.
Carrying capacity is affected by a couple of things:
0. Resource availability,: depending on how many resources there are in an ecosystem, it can only hold so many organisms.
,1. Space,: depending on how ,large, an ecosystem is, the denser the ecosystem (of organisms), the harder it is for the organisms to coexist. Therefore, the smaller the area, the lesser the carrying capacity.
These 2 factors (resources being biotic and space being abiotic) are the only factors few factors that affect carrying capacity.
Therefore, our best answer choice is A.

A patient with and O blood type can receive a transfusion from a donor with blood type ____ only.a) ABb) Oc) AB, A, or Od) AB, A, B, or Oe) AB, A, or B
Blood types are determined by the proteins present on the surface of the red blood cells.
• In blood type A, red cells have A antigens and there are anti-B antibodies in the plasma.
,• Blood type B has B antigens and anti-A anitbodies
,• Blood type AB has A and B antigens and no antibodies
,• Blood type O, has ,no antigens ,and ,both anti-A and anti-B antibodies.
Is important not to pair antigens and antibodies, as the antibodies of the recipient will attack the antigens.
For example, if a person with O blood type receives AB blood, the patient's anti-A and anti-B antibodies would attack the donor's blood because the red cells have A and B antigens.
This means that a person with O blood type can only receive blood type O because those red cells don't have any antigens on their surface (option b).

What is the difference between chromosomes, sister chromatids, non-sister chromatids, separated chromatids?
Chromosomes are structures of nucleic acids and protein carrying genetic information in the form of genes.
The chromosome is composed of two sister-chromatids.
During meiosis and mitosis, the sister chromatids are separated to separate half of the geentic material and create a new cell.
The difference between sister chromatids and non-sister chromatids is that sister chromatids have the same alleles in the same place and non-sister chromatids have different alleles in the same place. Non-sister chromatids will have the same length and configuration, but those different alleles will represent different types of the same characteristic (for example: different colors of fur). But they look the same as sister chromatids.

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 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.

Click the underlined phrase that uses I literally device to make Northridge Junction seem like a desperate person.
The phrase "he clung to an exposed ledge over the valley from which the train had left" Northridge Junction seems like a desperate person, because out of feeling and/or despair he clung, in this sentence the verb to grab makes it seem like a desperate way not to be in danger of life.
What is despair?Despair is an emotional state of extreme tension, anxiety and fear.
The person immersed in this state cannot get out easily, because his negative perception contributes to his always being down. When recurrent, it becomes clinical and can take control of emotions.
A hallmark of clinical despair is the meaninglessness of feeling. There are no imminent threats, suffering or dangerous circumstances. Even so, the person experiences this state again and again.
What are the causes for despair?Despair is associated with some mental disorders, such as depression, anxiety, post-traumatic stress disorder, and especially panic syndrome.
Commonly, it is also caused by negative events in the person's life, such as trauma, divorce, dismissal, death of a loved one, abuse, use of chemical substances, among others.

Since both the liver and skeletal muscle can store glucose as glycogen, both organs can break down the glycogen into free glucose to release into the blood.
a. true
b. false
Since glucose is required for muscle contractions, a proper glucose metabolism is crucial for optimal health.
What different role of glucose in liver and skeletal muscle?When the muscle contracts, the GLUT4 glucose transporter moves glucose from intracellular storage depots to the plasma membrane and T-tubules, allowing it to enter the muscle cell.
A little quantity of glucose is kept in the brain, but the majority of it is kept as glycogen in the liver and skeletal muscles.
Exercise-induced muscle contraction boosts glucose absorption in skeletal muscle in addition to insulin stimulation. The facilitative GLUT4 is redistributed from intracellular storage vesicles in response to both stimuli.
Therefore, it is false that both the liver and skeletal muscle can store glucose as glycogen.
