The most extreme wavelength dogs can detect sound is 0.0085 m.
What is wavelength?The is the distance of one complete cycle of a wave.
To calculate the most extreme wavelength dogs can detect sound, we use the formula below.
Formula:
v = λf................... Equation 1Where:
v = Speed of soundf = Frequency of soundλ = most extreme wavelength .make λ the subject of the equation
λ = v/f................ Equation 2From the question,
Given:
v = 340 m/sf = 40000 HzSubstitute the given values into equation 2
λ = 340/40000λ = 0.0085 m.Hence, The most extreme wavelength dogs can detect sound is 0.0085 m.

A cylinder has a height of 21 cm and a volume of 11,144 cm³. What is the radius of the cylinder? round your answer to the nearest whole number.
Answer:
13 cm
Explanation:
h = 21 cm, V = 11,144 cm^3
V = π r^2 h
so
[tex]r=\sqrt{\frac{V}{\pi h}}=\sqrt{\frac{11,144}{\pi\times21}}=13 cm[/tex]
Nuclear pores regulate the passage of substances into and out of the nucleus. Antibodies such as mab414 have been used to inhibit the movement of substances through the nuclear pores of rat liver cells. Scientists cultured rat liver cells (eukaryotic) and bacteria cells (prokaryotic) in separate dishes with radioactively labeled amino acids. A specific gene in both cell types was engineered to synthesize identical polypeptide chains, and translation of this gene was measured. The procedure was repeated with mab414 (the inhibitor) added to each of the two cell cultures, and translation was monitored again.

What is the aim of an experiment?The aim of the given experiment is to explain the translation in the prokaryotes and eukaryotes. In biology, translation in this case is defined as the production of protein from mRNA by translating a sequence of mRNA molecule to a sequence of amino acids.
Now, In eukaryotes, translation occurs in the cytoplasm and as a result, mRNA in the nucleus is transported to the cytoplasm. However, in prokaryotes, the cytoplasm acts as the nucleus which means that there is no need for the transportation of mRNA via Nuclear pores to the nucleus.

Express $8\sqrt{18}$ in the form $a\sqrt b$, where $a$ and $b$ are integers and $b$ is as small as possible.
8 √18 = 8 √(9 × 2)
= 8 √(3² × 2)
= 8 √(3²) √2
= (8 × 3) √2
= 24 √2
Answer:
24 √2
Explanation:
The largest square factor under the radical is $9$. This gives us the factorization $\sqrt{18} = \sqrt 9 \cdot \sqrt 2$. Thus
\begin{align*}
8\sqrt{18} &= 8(\sqrt 9\cdot \sqrt 2) \\
&= 8\cdot 3\sqrt 2 \\
&= \boxed{24\sqrt 2}.

Out of five men and five women, we form a committee consisting of four different people. Assuming that each committee of size four is equally likely, find the probabilities of the following events:.
The probabilities of the following events are 10/21, 11/42,41/42, and 2/15 respectively
How to find probabilitiesProbability of forming a committee consisting of two men and two women = (5C2 × 5C2) / 10C4
5C2 = 5! / 2!(5 - 2)!
= 5! / 2!3!
= 5×4× / 2×1
= 20/2
= 10
So,
(5C2 × 5C2) / 10C4
= 10×10 / 210
= 100/210
= 10/21
Probability of forming a committee consisting of two men and two women = 10/21
Probability of forming a committee that has more women than men. This means forming a committee that has 4 women, 0 men or 3 women 1 man
= {(5C3 × 5C1) + (5C4 × 5C0)} / 10C4
= {(10×5) + (5×1)} / 210
= (50 + 5) / 210
= 55/210
= 11/42
Probability of forming a committee that has at least one man. This means the committee must not have all women as members
= 1 - 5C4/10C4
= 1 - 5/210
= 1 - 1/42
= 41/42
Probability of forming a committee with both Alice and Bob are members of the committee. This means there are only two more people to join the committee from the remaining 8 people.
= 8C2 / 10C4
