If the stimulus reaches the threshold an action potential will be generated. If the stimulus doesn't reach it no action potential will be generated. If the stimulus will be stronger the action potential will have the same amplitude. The refractory period makes it harder to generate an action potential so they decrease the frequency of action potential production.

2. Cloning vectors are plasmids that are used primarily to propagate DNA. They replicate in E. coli to high copy numbers and contain a multiple cloning site

3a. Examples of cloning vectors are plasmids, cosmids, bacterial artificial chromosomes (BACs), and yeast artificial chromosomes (YACs).

3b. plasmids- small, BACs- large, YACs- large, cosmids- large

Explanation:

hope this helps

A cloning vector is a short piece of DNA which can be stably maintained in an organism, and into which a foreign DNA fragment can be inserted for cloning purposes.

A cloning vector is defined as a short piece of DNA that can be stably maintained in an organism, and into which an external DNA fragment can be inserted for cloning purposes. This may be DNA taken from a virus, the cell of a higher organism, or it may be a plasmid of a bacterium.

Cloning vectors are plasmids that are mainly used to amplify DNA which replicate at high copy number in E. coli and contain a multiple cloning site.

Examples of cloning vectors are plasmids, cosmids, bacterial artificial chromosomes (BACs), and yeast artificial chromosomes (YACs).

Thus, a cloning vector is a short piece of DNA which can be stably maintained in an organism, and into which a foreign DNA fragment can be inserted for cloning purposes.

Explanation:

O-16 and O-18 are isotopes as they have the same element (oxygen) but different atomic mass (16 and 18).

The symbol represents the atoms that are isotopes are O-16 and O-18, the correct option is b.

Isotopes are members of an element family that have the same number of protons but have different numbers of neutrons.

The atomic number of an element on the Periodic Table is determined by the number of protons in its nucleus. Carbon, for example, has six protons and is atomic number 6.

The mass of an isotope, which is the total number of protons and neutrons, is used to identify it. Isotopes are typically written in one of two ways.

The most common illustration are hydrogen as well as carbon isotopes. When it relates to the element Hydrogen, it has three stable isotopes: protium, deuterium, and tritium.

These isotopes share the same number of protons but differ in neutron count, with protium having zero, deuterium having one, and tritium having two.

Thus, the correct option is b.

Answer:

increase; decrease; increase; decrease

Explanation:

When Lake Mendota was completely covered with algae, biologists used the concept of trophic cascades to solve the problem by introducing predatory fish. When they did this, an increase in predatory fish caused a decrease in plankton feeding fish, which resulted in an increase in herbivorous plankton with a consequent decrease in algae.

With the introduction of predatory fish, a decrease in the population of zooplankton-eating fish would occur due to predation by the newly introduced fishes. This will cause the population of zooplankton to thrive or increase.

Zooplanktons feed on algae. Hence, an increase in their population will put pressure on the alga in the ecosystem and cause a decrease in their population.

Explanation:

The acceleration maxes out everything

Complete question:

The Hardy-Weinberg equilibrium is a theoretical model that predicts the frequency of different genotypes in a population that is not evolving. A scientist studying the population genetics of the rainbow fish finds that the Hardy-Weinberg model predicts that the frequencies of the three different genotypes for the albino gene in a given lake should be as follow: AA: 49%, Aa: 42%, and aa: 9%. However, the scientist obtained a sample of 320 individuals of this species and found that the numbers of individuals for the different genotypes are: AA: 180, Aa: 120, and aa: 20. Use the appropriate statistical technique to test (use alpha = 0.05) whether the observed genotype frequencies are consistent with eh Hardy-Weinberg model. State your conclusion.

Answer:

There is enough evidence to reject the null hypothesis. The genotypes are not in equilibrium.  The genotype frequencies are consistent with the Hardy-Weinberg model.

Explanation:

Expected Number of individuals with each genotype:  Each genotype´s frequency multiplied by the total number of individuals in the sample.

AA= 0.49 x 320 = 156.8

Aa= 0.42 x 320 = 134.4

aa= 0.09 x 320 = 28.8

Observed Number of individuals with each genotype:

AA= 180

Aa= 120

aa= 20

Chi square= ∑ ((O-E)²/E)  

AA= (O-E)² /E

AA= (156.8 - 180) ² / 156.8

AA= 538.24/156.8

AA= 3.433

Aa= (O-E)² /E        

Aa= (134.4-120)² / 134.4

Aa=207.36/134.4

Aa= 1.543

aa= (O-E)² /E

aa= (28.8-20)²/28.8

aa= 2.69

X² = ∑ ((O-E)²/E) =  3.433 + 1.543 + 2.69 = 7.666

Freedom degrees =  genotypes - alleles = 3 - 2 = 1  

Significance level, 5% = 0.05

p value less than 0.05

Table value/Critical value = 3.841

7.666 > 3.84 meaning that the difference between the observed individuals and the expected individuals in each chamber is statistically significant.

There is enough evidence to reject the null hypothesis. The genotypes are not in equilibrium.

Answer:

[tex]f=5.6\times 10^{14}\ Hz[/tex]

Explanation:

The resulting light have a wavelength of 532 nm.

We need to find frequency of the material. Let it is f.

The relation between frequency and the wavelength is given by :

[tex]c=f\lambda\\\\f=\dfrac{c}{\lambda}\\\\f=\dfrac{3\times 10^8}{532\times 10^{-9}}\\\\=5.6\times 10^{14}\ Hz[/tex]

So, the frequency of the light is [tex]5.6\times 10^{14}\ Hz[/tex]. Hence, this answer is correct.

Answer:

Many consumers are interested in buying from companies that consider animal welfare.

Explanation:

Factory farms, also known as Operators of concentrated animal feeding operations (CAFOs) are interested in maximizing their production efficiency to increase their profits, regardless of the animals´ health and growing conditions. These factories tend to prioritize rapid growth and production over animal welfare, which might be an important reason to think that they do not care about the quality of their product, more than they do about their earnings.

Since during the last years, there is a sharp increase in the people´s conscientization of animal welfare and the conditions in which they are grown, probably the most effective argument for the improved treatment of animals in CAFOs is that many consumers are interested in buying from companies that consider animal welfare.

People who care about animal conditions will not consume animal products from factory farms, which eventually ends by affecting these factories´ profits. If CAFOs improve animal treatment and get higher animal welfare standards, they will have more people consuming their products, which is basically their main interest.
