The correct answer to the question is Option D) RNA uses Uracil, DNA uses Thymine.
What are the differences between DNA and RNA?
The sugar deoxyribose is found in DNA, while ribose is found in the RNA.
DNA is a double stranded molecule, whereas RNA is a single-stranded one.
DNA is very stable under alkaline environments, but RNA is not.
In humans, DNA and RNA have distinct purposes. DNA is in charge of storing and transmitting genetic information, whereas RNA directly codes for amino acids and serves as a messenger between DNA and ribosomes in order to produce proteins.
DNA and RNA base pairing differ somewhat because DNA utilises adenine, thymine, cytosine, and guanine whereas RNA uses adenine, uracil, cytosine, and guanine. Uracil differs from thymine in that its ring lacks a methyl group.
To conclude with we can say that Uracil is contained in RNA but not in DNA. Uracil creates two hydrogen bonds with adenine in RNA.Thymine replaces uracil as the nucleo base in DNA. Uracil can be thought of as a demethylated version of thymine. Each nucleotide of RNA has a ribose sugar, with carbons numbered 1' through 5'. A base, often adenine (A), cytosine (C), guanine (G), or uracil, is added to the 1' position (U). Purines are adenine and guanine and pyrimidines are uracil.

A therapist examining the roles, rules, expectations, power hierarchy, and boundaries within a
family is focused on which of the following areas of assessment?
Answer:
This question lacks options, options are:
A) family affect
B) family strengths
C) family process
D) family organization.
The correct answer is D.
Explanation:
The family is a system that is constituted by a network of relationships and made up of subsystems where each member evolves and develops through different stages, undergoing adaptation changes where the norms, rules, limits and hierarchies that work are essential in the family environment. Family therapy is understood to be that modality of therapy focused on the family as an object of intervention, its objective is to achieve the change of negative interaction patterns between the members of a family. Family organization refers to the interaction between all its members who are part of the same institution united by emotional ties. The organization describes the totality of the existing relationships between the people that make up the system, then the family organization refers to the functional demands, distribution of rules and transactional guidelines that constitute the ways of interacting of each individual within the family. The transactional guidelines are those that normalize the behavior of each member and are preserved by two systems of coercion; the first established by universal norms in turn existing roles and hierarchies; the second is the characteristic of each member involving its interests and expectations.

Which of the following lists correctly presents levels of organization from most complex to simplest?
O biosphere, community, organism, organ system
O cell, organelle, atom, molecule
O macromolecule, population, community, ecosystem
Answer:
O macromolecule, population, community, ecosystem
Explanation:
Macromolecules are very large molecules composed of atoms, such as complex carbohydrates, fats and proteins (for example, fats are macromolecules mainly composed of C, H, and O atoms). Macromolecules in turn associate to form cellular structures (eg. organelles, cytoskeleton, etc), which subsequently combine to form cells. Individuals are made up of one or more cells (i.e., unicellular and multicellular organisms, respectively). In the next level, populations are groups of individuals of the same species that live within a given area; whereas communities are groups of populations that live in a given area and interact with one another. Finally, an ecosystem can be defined as a group of populations (i.e., a community) and the abiotic factors (i.e., nonliving parts) of their environment that support them (e.g., water, light, radiation, temperature, etc).

What happens when a cycle res turns to its starting point
Explanation:
Now that we’ve learned how autotrophs like plants convert sunlight to sugars, let’s take a look at how all eukaryotes—which includes humans!—make use of those sugars.
In the process of photosynthesis, plants and other photosynthetic producers create glucose, which stores energy in its chemical bonds. Then, both plants and consumers, such as animals, undergo a series of metabolic pathways—collectively called cellular respiration. Cellular respiration extracts the energy from the bonds in glucose and converts it into a form that all living things can use.

Risk assessment is often used to set “acceptable” levels of toxins for the environment. Propose a concern people may have about using risk assessment in this way.
The concern about risk assessment of acceptable levels of toxins can be a failure to use appropriate risk metrics, incorrect measuring of known risk, failure to take known risks into concern, or failure in risk communication or risk monitoring.
What is meant by risk assessment?A risk assessment is a step-by-step process that, in combination with an exposure analysis and other elements, provides an estimate of the likelihood that an adverse health event will occur as a result of ingestion, inhalation, or absorption of one or more toxins. One of the most important aspects of risk assessment is toxicity assessment.
A toxicity assessment is a study of a substance’s ability to cause harm – and how much harm it can cause. It’s important to note that not all substances are toxic – many therapeutic medications are acute toxic but beneficial when taken at the right dose.

Imagine a continuation of the experiment described above. How might NS3/4A expression impact Sendai virus replication, as measured by the amount of virus produced by the different cells? a. Cells expressing NS3/4A will produce more Sendai virus than cells that do not express NS3/4A. b. Cells expressing NS3/4A will produce less Sendai virus than cells that do not express NS3/4A. c. The two types of cells will produce roughly equal amounts of Sendai virus.
Answer:
The correct answer is - a. Cells expressing more NS3/4a will produce more Sendai virus than cells that do not express NS3/4a.
Explanation:
NS3/4a is a multiprotein serine protease that is a non-covalent heterodimer consisting of a catalytic subunit protein. This heterodimer has an N-terminal one-third of NS3 protein and at an activating cofactor (NS4A) protein.
It acts as an antagonist for cytokine promoters. Thus in the absence of cytokines or reduced levels of cytokines due to inactive promoters) the expression of the virus would increase.

a que distancia se encuentra una gaviota respecto del nivel del mar?
Answer:
Para determinar la distancia a la que se encuentra una gaviota respecto del nivel del mar, es necesario medir la altura a la que se encuentra volando. Así, dado que el nivel del mar tiene una altura considerada como de 0 metros, si la gaviota está volando a unos 500 metros de altura, por ejemplo, esa será su distancia respecto del nivel del mar.
