Some theories are developed from repeated testing of a single hypothesis. Cell theory, germ theory, and the theory of evolution all have developed from the testing of multiple related hypotheses. Which statement best explains why some theories develop this way?
-A hypothesis tests many variables at once, which can lead to new hypotheses.
-Multiple related hypotheses will become theories before a single hypothesis does.
-Each scientist has used different wording when developing his or her hypothesis.
-Each experiment reveals a different piece of information that is needed to develop the theory.

If the frequency of the disorder in the population is 0.0070, what is the percentage of heterozygous carriers

Answers

Answer:

15.322 %

Explanation:

Supposing that this is a recessive disorder and the population is in Hardy-Weinberg equilibrium:

p² + 2pq + q² = 1, where

1- the genotypic frequency of the homo-zygous dominant allele is p²,  

2- the genotypic frequency homo-zygous recessive allele is q², and

3- the genotypic frequency heterozygous allele is 2pq  

Therefore:

q² = 0.007 >> q = √ 0.007 = 0,0836  

p = 1 - q = 1 - 0,0836 = 0.9164

2pq = 2 x 0.9164 x 0,0836 = 0.15322 (or 15.322 %)

What prevents acetylcholine from accumulating in the neuromuscular junction and causing a sustained contraction in a normal individual

Answers

Answer:

Botulinum toxin

Explanation:

Botulinum toxin is known to hinder the release of acetylcholine into the synaptic cleft at the neuromuscular junction.

This leads to acetylcholine not attaching to its receptors and eventually leading to the inability to have muscle contractions.

Hence, in this case, the correct answer is Botulinum toxin prevents acetylcholine from accumulating in the neuromuscular junction in individuals.

Which of the following statements BEST defines vestigial structures? :
-Structures that are different in different organisms
-Structures that are still present but currently serve little to no purpose
-Structures that are the same in different organisms
-Structures that are different between the infant and adult forms of an organism

Answers

Answer:

Structures that are still present but currently serve little to no purpose

Explanation:

Vestigial structures/organs are general defined as structures/organs that are present but poorly developed without any functional use in the present living organisms but thought to have been fully developed and functional in their ancestors.

Fully developed and functional organs gradually become less developed and non-functional across generations as the environment keeps changing and organisms found lesser use for the organs. An example includes the caudal vertebrae found in man which is kind of useless but thought to have been fully developed and functional in the ancestors of man - the monkeys.

Vestigial organs are often used as one of the morphological evidence of the evolution of living organisms.

S. cerevisiae occurs in nature on ripe fruit. S. epidermidis naturally occurs on human skin. How do experimental results relate to the natural environment of each microbe?

Answers

Answer:

S. cerevisiae needs natural environment present on ripe fruit while S. epidermidis needs natural environment present on human skin.

Explanation:

S. cerevisiae occurs in nature on ripe fruit because the environment is suitable for them that provides food in the form of sugar while S. epidermidis naturally occurs on human skin because it needs wet and humid environment which is available on human body such as armpits. Due to the presence of suitable environmental condition, both S. cerevisiae and S. epidermidis are present on fruits and human skin respectively.

55) Cells require which of the following to form cilia or flagella?
A) centrosomes
B) ribosomes
C) actin
D) A and B only
E) A, B, and C

Answers

Answer: D) A and B only

Explanation:

Centrosomes and Ribosomes are both present in the animal cell with both of them having different roles. Centrosomes have roles in cell divisions as they maintain chromosome number during the process and Ribosomes are in charge of the synthetization of proteins.

These two share a role together which is that they are both needed by the cell in order to form either cilia or flagella.

What are the charges both inside and outside of the neuron before you click the stimulate neuron button?

The correct approach is "Negative and Positive".

Explanation:

Just outside of the neurons, the electrostatic interactions seem to be extremely favorable or positive (+) as well as the ion mostly with the greatest proportion was indeed sodium. Throughout intracellular space, a large amount of protein would be negatively charged, or even just potassium channels predominate. Under those same circumstances, the ion channels also seem to be inaccessible.

Which scientific discipline is correctly matched to a contribution to society?

Answers

The options are;

A) biology; theory of relativity

B) geology; theory of continental drift

C) ecology; discovering new elements

D) astronomy; developing quantum mechanics

Answer:

B) geology; theory of continental drift

Explanation:

Looking at the options;

-theory of relativity is a topic in physics originated by Einstein. Thus, it is matched to physics and not biology.

- theory of continental drifts are related to plate tectonics where it explains how continents shift position on Earth's surface. This is a branch of Geography and is thus correctly matched.

- discovering new elements is a topic under chemistry and not ecology. Thus, this is not matched correctly.

-developing quantum mechanics is a topic in physics that deals with the relationship between energy and matterwith respect to atomic and subatomic scale. Thus, it is not well matched.

Therefore correct answer is option B

Answer:

The answer should be A. lithosphere.

Explanation:

Firstly, let's look at the options:

C. and D, both parts of the Earth at the core, have almost nothing to do with the Earth's crust or tectonic plates except maybe having a passive effect on them.

B. mantle is where the lava that moves the tectonic plates circulates due to convection, which is the reason they move at all. But, it is not where the tectonic plates themselves are.

Therefore, finally, we have A as the answer.

(As a sidenote, the "lithosphere" means the Earth's crust.)

Hope this helped!

The lithosphere contains the tectonic plates, so that’s the answer.

How can traits affect fitness and how

Answers

Answer: Natural selection allows the survival of organisms with beneficial traits.

Explanation:

Natural selection can be defined as the differential survival and reproduction of the members of the population that have beneficial phenotypic traits to survive in unfavorable environment. These organisms reproduce and pass on their traits to the next generation such species does not extinct in future.

The natural selection allows evolution of species with the adaptation of new traits so as to allow the survival of the organism.

3. On a particular planet, it takes 850 J for a 50 kg remote probe to launch
itself up 2 m. What is the gravitational field strength on the planet?

Answers

Answer:

the gravitational field strength is 8.5 N/kg .

Explanation:

PE = mgh

where,

PE is Potential Energy

m is the mass

g (a) is the acceleration

h is the height

Substitute the value we get

→ 850 = 50×a × 2

→ 850 = 100×a

→ a = 850/100

→ a = 8.5m/s²

Acceleration is 8.5m/s².

Now, Calculating the Gravitational Field Strength
