List The Angles In Order From Smallest To Largest. Note Image In Not Drawn To Scale

Answers

Answer 1

Using sine rule and cosine rule, the angles from smallest to largest is A,B,C.

Using the cosine rule;

a^2 = b^2 + c^2 - 2bc cos A

When;

a = 9 cm

b = 16 cm

c = 18 cm

9^2 = 16^2 + 18^2 - (2 × 16 × 18) cos A

81 = 256 + 324 - (576) cos A

81 = 580 - 576 cos A

81 - 580 = - 576 cos A

cos A = (81 - 580)/  - 576

A = cos-1[(81 - 580)/  - 576]

A = 30°

Using the sine rule;

a/sin A = b/sinB

asinB = bsinA

sinB = bsinA/a

B = sin-1(bsinA/a)

B = sin-1[(16 × sin30)/9]

B = 63°

Now;

A + B + C = 180(Sum of angles in a triangle)

C = 180 - ( A + B)

C = 180 - ( 30 + 63)

C = 87°

The angles are A, B, C.

The β chains of HbA and HbS were treated with trypsin, and the sequence of the N-terminal tryptic peptides are as given below. Do these peptides separate from each other in an electric field if the pH is 7.0? Explain in detail the reasoning behind your answer and include your calculations for the charge of each peptide in your answer.

HbA: Val-His-Leu-Thr-Pro-Glu-Glu-Lys

HbS: Val-His-Leu-Thr-Pro-Val-Glu-Lys

Answers

Yes The two peptides will separate from each other in an electric field when the pH is 7.0

The two peptides wil drift/separate from each other when the pH is 7.0 because of the reaction of trypsin enzyme and also the difference in charge between HbA and Hbs

Considering charge of each peptide

Since The isoelectric point of normal Hba is 6.9 and Hbs possess two fewer negative charges per hemoglobin molecules

The Hbs is more hydrophobicity than HbA due to the substitution of glutamic acids of HbS by valine residue.

Considering Electrophoresis

At a lower pH level Hbs shows a slower moving band than Hba

while a higher pH level the HbS peptide is less negatively charged while the carboxyl group of HbA is more negatively charged and Hba moves faster as well as an acidic pH.

Hence we can conclude that the two peptides will separate from each other in an electric field when the pH is 7.0

Which of the following ecological levels does not describe interacting biotic and abiotic factors in an area?

A. Biome
B. Community
C. Ecosystem
D. Habitat

Answers

Answer:

habitat

Explanation:

The ecological levels do not describe interacting biotic and abiotic factors in an area's habitat. The correct option is D.

What is a habitat?

A habitat is a place where physical or biotic factors are presented. This is a place where all the factors are present to live a species with all suitable conditions.

Habitat of different species is different. They live in their suitable habitat to grow and reproduce accordingly. If a species is moved from its habitat, then it may have difficulties in surviving.

So habitat is not a place where all biotic and species abiotic factors are present, it is a place where all living factors are present that are necessary for the living of a person. So, it is not the ecological level of  interacting biotic and abiotic factors in an area

Thus, the correct option is D. Habitat.

Pleaseeee someone help me . What is the half life of Caron 14 of this problem ???

Answers

Answer:

5730 years

Explanation:

In a chemical reaction, including radioactive decay, the half-life of a species is the time taken for the substance to decrease to exactly one-half its initial value.

For a first-order reaction, the half-life of the reactant is

                                                  [tex]t_{\frac{1}{2}} \ = \ \displaystyle\frac{\ln 2}{\lambda} \ \ \ \ \ \ (1)[/tex],

where λ is the reaction's rate constant modeled by the differential equation describing the kinetics of a first-order reaction

                                               [tex]N \ = \ N_{0}e^{-\lambda t} \ \ \ \ \ (2)[/tex],

where N is the remaining amount of substance after time t and [tex]N_{0}[/tex] is the initial amount of substance before the chemical reaction proceeds.

Since the value of λ is constant, rearrange equation (1) with λ as the subject,

                                                       [tex]\lambda \ = \ \displaystyle\frac{\ln 2}{t_{\frac{1}{2}}}[/tex].

Given that only 12.5% of carbon-14 remained after 17190 years assuming that initially there was 100% of carbon -14, substitute in the values into equation (2) and solve for λ (make λ the subject of the equation),

                               [tex]\-\hspace{0.56cm}12.5 \ = \ 100e^{-\lambda \times 17190} \\ \\ \-\hspace{0.5cm} \displaystyle\frac{12.5}{100} \ = \ e^{-17190\lambda} \\ \\ \displaystyle\frac{\ln\displaystyle(\frac{1}{8})}{-17190} \ = \ \lambda \\ \\ \-\hspace{1.05cm} \lambda \ = \ \displaystyle\frac{3\ln2}{17910} \ \ \ \ \ \ \ \ \ \ (\ln \displaystyle\frac{1}{x} \ = \ -\ln x\ ; \ \ln x^{n} \ = \ n\ln x )[/tex]

Equate both λ,

                                            [tex]\displaystyle\frac{\ln 2}{t_{\frac{1}{2}}} \ = \ \displaystyle\frac{3\ln2}{17190} \\ \\ \-\hspace{0.26cm} t_{\frac{1}{2}} \ = \ \ln 2 \ \times \ \displaystyle\frac{17190}{3\ln2} \\ \\ \-\hspace{0.26cm} t_{\frac{1}{2}} \ = \ \displaystyle\frac{17190}{3} \\ \\ \-\hspace{0.26cm} t_{\frac{1}{2}} \ = \ 5730[/tex]

*Note that the above calculations demonstrated that carbon-14 went through 3 half-lives to yield a remaining 12.5% of its original amount, since

                                 [tex]100\% \ \overset{t_{\frac{1}{2}}}\longrightarrow \ 50\% \ \overset{t_{\frac{1}{2}}}\longrightarrow \ 25\% \overset{t_{\frac{1}{2}}}\longrightarrow \ 12.5\%[/tex].

Therefore, if n is the time taken for carbon-14 to half its initial amount trice to remain 12.5% of its initial amount. Then, the half-life of carbon-14 is [tex]\displaystyle\frac{n}{3}[/tex].

Which of the following are characteristics of the tundra biome? (Choose all that apply.)
much rainfall throughout the year
low biodiversity
very cold temperatures
lack of trees

Answers

Answer is very cold temperatures, lack of trees and low biodiversity

The Tundra is defined mainly by permafrost, lack of trees, low biodiversity, and harsh conditions. It occupies the area between the polar ice caps and the boreal forests (or taiga).

The tundra biome is characterized by extremely cold temperatures and treeless, frozen landscapes. There are two types of tundra, the arctic tundra and the alpine tundra.

The World’s Ice Deserts: The Tundra Biome

The tundra is the coldest of all the biomes with an annual average temperature of less than 5°C, and precipitation (mostly in the form of snow) less than 100 mm per year. The weather conditions at tundra are so harsh that only a handful of plants and animals can even survive there. The word tundra comes from the Finnish word ‘tunturia’ which means treeless plain.

The tundra is one of the least understood and most fascinating biomes on the planet. This incredibly difficult climate and the environment have both a bizarre and diverse range of animals that have learned to survive with the limited amounts of green plant life, sunlight and moisture. Due to extremely cold temperatures, the layer just below the surface remains permanently frozen. This frozen layer of ground is called ‘permafrost.’

A lack of trees, a lack of biodiversity, and extreme circumstances are what most clearly identify the tundra.

What is Tundra Biome?

The polar ice caps and the boreal woodlands (also known as taiga), it is located. Extremely low temperatures and barren, icy terrain define the tundra biome. The arctic tundra and the alpine tundra are the two different forms of tundra.

The Tundra Biome: The Ice Deserts of the World. The tundra is the coldest biome, with an average annual temperature of less than 5°C and yearly precipitation of less than 100 mm, most of it snow.

Only a few number of plants and animals can even thrive on the tundra due to its extreme weather conditions. The Finnish term "tunturia" is where the word "tundra" originates.

Therefore, a lack of trees, a lack of biodiversity, and extreme circumstances are what most clearly identify the tundra.

Why is it that dominant diseases are not as common as recessive ones?

Answers

Answer:

Mainly because if a disorder is dominant, then it will be manifested by all who have the gene. If the disorder is severe, then it will reduce the chances of the individual surviving to grow up and reproduce (unless the disorder only manifests symptoms in later life). If they do reproduce, then 50% of their offspring will inherit the gene, and be at a similar disadvantage in reproduction. Thus, there is likely to be selection against the gene. By contrast, a recessive disorder is only manifested if both parents pass on the abnormal gene, and an individual with one gene for the disorder is usually at no disadvantage. Thus, there is much less selection against abnormal recessive disorders.

Simone is creating a model to track the movement of carbon atoms in an ecosystem. Which statement best explains the role of plants in Simone's model?

Answers

Although I cannot see the model for Simone's experiment, I can offer the insight that the most likely role of plants in the model is that they consume the carbon atoms and produce oxygen.

How do plants affect the carbon in the atmosphere?Plants are known to have a great effect on the carbon levels of the atmosphere. The correlation is that the more plants are present, the less carbon is free in the air. The reason for this is that plants use carbon dioxide as a substrate to manage the process of photosynthesis.As a by-product, after consuming carbon dioxide and completing photosynthesis, plants release oxygen into the atmosphere.

Therefore, we can confirm that the most likely role of plants in the model created by Simone, is that they will consume carbon atoms in the form of carbon dioxide in order to sustain photosynthesis, which releases oxygen.

The smaller flashlight has less inertia than the larger flashlight, so it takes

less force to change the motion of the smaller flashlight.

Inertia is defined as the property of an object to resist changes in its velocity

when in motion. A larger or bigger body has more mass and inertia as it

requires more force to change the direction of the object.

The smaller flashlight has less inertia than the larger flashlight and hence
