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.

Answers

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.

Reasoning

Answers

Answer:

no.

Explanation:

the conclusion was in fact inaccurate, because plant B received 4hours of more sunlight than that of plant A, causing biased results.

The conclusion the student came to was not true. The results of the plants are biased because of different amounts of sunlight.
The plants were given different amounts of sunlight so the results can not be accurately compared. Therefore the results of the test are bused because of different sunlight times.

Answers

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.

Agrarian type of society does the image most likely represent. So, the correct option is B.

What is Society?

A group of people who live in one place and share customs, cultures, organizations, and interests is referred to as a society. The diversity of people from different religions, castes, genders, and ethnic groups has several effects on this civilization.

Agricultural activities generally include everything that has a close connection to farming and makes use of land for farming and crop production. This activity, which uses a variety of contemporary techniques, has a close relationship with all human agricultural operations and is in charge of the massive crop output.

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

Answers

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).

The correct option is  macromolecule, population, community, ecosystem

Answers

Answer:

uses light as its energy source and carbon for organic compounds.

Explanation:

The purple non-sulfur bacteria which depends on light produces organic food  just like plants through the process of photosynthesis. The purple non-sulfur bacteria uses carbondioxide and water with sunlight produces oxygen and glucose which is an organic compound. So that's why purple non-sulfur bacteria is also known as phototrophic means organism that produces their own food through photosynthesis.

A therapist examining the roles, rules, expectations, power hierarchy, and boundaries within a
family is focused on which of the following areas of assessment?

Answers

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.
