Globin is the protein part of hemoglobin.

The alpha globin family is located on chromosome 16.

The beta globin family is located on chromosome 11.

The answer is: d.) On different chromosomes. 

-------------

The vast majority of genes encoding a protein encoded within the nucleus of metazoan cells contain both introns and exons. 

The answer is: b.) both exons and introns. 

-----------------

In the DNA sequence the coding content of a gene is not continuously distributed along said gene, but has discontinuities, called introns, whose sequence does not encode proteins.

The answer is: a.) Intron.

Which of the following scenarios will cause the current to stop flowing within a circuit?

statuscvo [17]

A. The switch within the closed circuit is opened.

If the switch is opened current will stop flowing, as the current will meet a gap, that is not connected by a conductor.

A man pushes an 80-N crate a distance of 5.0 m upward along a frictionless slope that makes an angle of 30 with the horizontal.

laiz [17]

Answer:

The work done by the man is 260 J.

(E) is correct option.

Explanation:

Given that,

Force = 80 N

Distance = 5.0 m

Angle = 30°

Acceleration = 1.5 m/s²

Let F be the man's force

We need to calculate the force

Using balance equation

$F-mg\sin\theta=ma$

$F-80\sin30=\dfrac{80}{9.8}\times1.5$

$F=\dfrac{80}{9.8}\times1.5+80\sin30$

$F=52\ N$

We need to calculate the work done by the man

Using formula of work done

$W=F\dotc d$

$W=52\times 5.0$

$W=260\ J$

Hence, The work done by the man is 260 J.

a body of mass 5kg falls from height of 10m above the ground what kinetic energy of the body before it strike the ground

Snowcat [4.5K]

Gravitational Potential Energy (GPE) before fall = Kinetic energy on impact
GPE = mgh
GPE = 5kg x 9.8m/s^2 x 10m
GPE = 490 J
Kinetic Energy = 490 J

(This is assuming that gravitation field strength (g) is 9.8m/s^2, sometimes you may round this to 10m/s^2, therefore making the final result:
Kinetic energy = 500 J)

We now slowly increase the pressure to 15464.04 Pa while keeping the temperature constant. What is the final volume?

Mila [183]

Answer:

Final volume = 0.42 cubic meters

Explanation:

The question is incomplete. The initial conditions are

Initial temperature , $T_{1}$ = 310 K

Initial volume , $V_{1}$ = 0.5 cubic meter

Number of moles = 2.5

Since, from the ideal gas equation we get,

PV = nRT

P $\times 0.5 = 2.5 \times 8.314 \times 310$

$P_{1}$ = 12886.7 Pa

Final pressure= 15464.04 Pa

Since temperature is constant,

PV = constant

$12886.7 \times 0.5 = 15464.04 \times V$

V = 0.42 cubic meters.

Hence final volume = 0.42 cubic meters

A negatively-charged ion always has more what?

lina2011 [118]

The negative charge comes from the electrons.

An ion is negatively charged means it has more number of electrons compared to protons.

Thus, a negatively-charged ion always has more of ELECTRONS.
