After basketball practice, Tyler began feeling a sharp pain in his knee. He visited the doctor and found out that he had torn one of the many ligaments in his knee. Which of the following best describes the function of the ligament he injured?Immersive Reader
(1 Point)
A. Connecting cartilage to muscles
B. Cushioning the ends of bones
C. Connecting bones to other bones
D. Connecting muscles to bone

Answers

Answer:

C. Connecting bones to other bones

Explanation:

Ligament is one of the connective tissues in living systems whose primary function is to connect bones to other bones. Ligaments are made up of a short band of tough fibre making it adapted to that connective function.

In this question involving Tyler who is diagnosed to have torn one of his knee ligaments, it means he has torn one of the many connective tissues that connects his bones to another bone in the knee.

There are two species of squirrel in the United Kingdom: red squirrels and gray squirrels. Red squirrels are native to the United Kingdom while gray squirrels were introduced to the United Kingdom from North America in 1876. Figure 1 show the distributions of the two squirrel species in 1945 and 2010.

Answer:

The grey squirrel has increased their rate of emigration to the UK

The grey squirrel has increased their rate of emigration to the UK.

What is emigration?

Emigration is the act of relocating away from a resident country or place of residence (to permanently leave a country). Contrarily, immigration refers to the flow of individuals from one country into another (to permanently move to a country).

A migrant leaves their home nation and moves to their adopted one. Emigration and immigration thus both describe migration, but from the perspectives of various nations.

Demographers look at the push and pull factors that cause people to be drawn to one place and pushed away from another. Desires to escape unfavorable situations, such as scarcity of land or employment opportunities, or unfair treatment, are possible.

Therefore, The grey squirrel has increased their rate of emigration to the UK.

Answers

Answer: wdym u already answered it

Explanation:

In other cases, researchers use natural experiments in which the dependent variable (typically a measure of organism health) is measured under differing contexts that are not manipulated. Say, for example, that an accidental chemical spill contaminates five ponds. To determine the possible effects of the toxic chemical on frogs, a researcher could compare the hatching rate of frog eggs laid in those five ponds to the hatching rate of eggs laid in five uncontaminated ponds nearby. This would be an example of a natural experiment because concentrations of the toxic chemical in the ponds were not controlled by the experimenter, but rather resulted from the chemical spill.
Drag type of experiment on the left to the example of experiment on the right.
A. Natural
B. Manipulative

6. ______: Growth of corn plants is compared in field plots sprayed with three different dosage:s of weed killer 7.
7. ______: BPA concentrations in the urine of people with diabetes are compared to BPA concentrations in the urine of people without diabetes

Answers

Answer:

1. Natural

2. Natural

3. Manipulative

4. Manipulative

5. Manipulative

6. Manipulative

7. Natural

Explanation:

1. Checking the blood concentration of BPA in college students in relation to their recent consumption of canned food items is a natural experiment because BPA concentration in blood is not artificially controlled by any means.

2. Comparing the feeding behavior of fish in streams with acidic runoff to that of fish in an unaffected stream is a natural experiment due to the fact that the acidity of the stream is not artificially controlled in any way by the experimenter.

3. Checking the deformity rate in baby birds from nests in pesticide-sprayed fields and that from unsprayed fields would require some manipulations except a sprayed and unsprayed one already existed long before the experiment was given birth to. Otherwise, the sprayed field might need to be artificially created just for the purpose of the experiment.

4. A known carcinogen would need to be administered to a group of the mice. This is manipulative.

5. The tadpoles would need to be artificially exposed to the toxic metals in the laboratory. Manipulative

6. The spraying would need to be carried out artificially in order for the comparison to be made. Manipulative

7. People with diabetes cannot be artificially created. They must have existed naturally long before the experimental design. Natural

What is the role of an enzyme in a reaction with the reaction ? would the reaction happen without an enzyme?

Answers

Answer:

Enzymes are not used up in a chemical reaction. Usually, the enzyme will “reset” and be ready to use in another reaction. This is due to the fact that enzymes are proteins, and their shape is what they use in a chemical reaction.

Explanation:

Enzymes serve a similar purpose for chemical reactions in an organism's body, which is to lower the amount of "activation energy" needed for a particular chemical reaction to occur. Without enzymes, many chemical reactions would occur at a much slower rate because the amount of activation energy required would be far greater.

Besides helping to discover the structure of DNA, describe two other contributions Rosalind Franklin made to the world of science.​

Answers

Answer: Rosalind Franklin discovered the density of DNA and, more importantly, established that the molecule existed in a helical conformation. Her work to make clearer X-ray patterns of DNA molecules laid the foundation for James Watson and Francis Crick's suggestion that DNA is a double-helix polymer in 1953.

Explanation:

Rosalind Franklin made numerous contributions to science in addition to helping to discover the structure of DNA, and in the field of virology, in coal-based materials, by using X-ray crystallography, in agriculture, etc.

What is the contribution of Rosalind Franklin?

She was one of the greatest scientists who made significant contributions to the field of DNA by using X-ray crystallography, and apart from that, she also made contributions to the field of virology. As X-ray diffraction facilitates the study of the structure of viruses such as the tobacco mosaic virus and the polio virus and helps in understanding the replication of viruses, it is also helpful in the study of the structure of coal and other carbon-based materials.

Hence, Rosalind Franklin made numerous contributions to science in addition to helping to discover the structure of DNA, and in the field of virology, in coal-based materials, by using X-ray crystallography, in agriculture, etc.

Yellow light travels through a certain glass block at a speed of 3 * 108 m/s . The wavelength of the light in this glass is 3.81 * 10 - 7m . What is the frequency?

Answers

Answer:

f = 7.87×10¹⁴ Hz

Explanation:

Given data:

Speed of light = 3×10⁸ m/s

Wavelength of light = 3.81 ×10⁻⁷ m

Frequency of light = ?

Solution:

Formula:

Speed of wave = wavelength × frequency

Now we will put the values in formula.

3×10⁸ m/s = 3.81 ×10⁻⁷ m × f

f = 3×10⁸ m/s /  3.81 ×10⁻⁷ m

f = 0.787 ×10¹⁵ s⁻¹

   s⁻¹  = Hz

f =  0.787 ×10¹⁵ Hz

f = 7.87×10¹⁴ Hz
