The gel electrophoresis shows the result of the child's DNA, the mother's DNA, and the three paternal DNAs, and out of them, one is the father. As the child's DNA matches that of the mother and dad 3,

The paternity test is done to test the real father of the child by comparing the child's DNA with the parents' DNA. It gives the result based on the DNA analysis, and here the test is shown in the gel electrophoresis. Gel electrophoresis shows the DNA segments of the child, mother, and three men, but the child DNA segments match the DNA segment of the dad 3. The child's DNA segments match with the mother, and the rest match with Dad 3, confirming that Dad 3 is the child's biological father.

Hence, out of them, one is the father, and the child's DNA matches that of the mother and Dad 3.

Answer:

2.41 × 10^24 molecules

Explanation:

To calculate the number of molecules of a substance (nA), we multiply the number of moles of such substance (n) by Avagadro's number or constant, which is 6.02 × 10^23.

That is; nA = n × 6.02 × 10^23.

In this question, 4 moles of glucose were given. The number of molecules in 4 moles of glucose is as follows:

nA = 4 × 6.02 × 10^23

nA = 24.08 × 10^23

nA = 2.41 × 10^24 molecules.

Answer: b

Explanation:

Based on these criteria, the watershed that contains the healthier stream is, that both streams are equally healthy. The correct option is B.

An abiotic factor is a non-living component of an ecosystem that influences its surroundings. Temperature, light, and water are all components of the terrestrial environment.

Abiotic elements in a marine ecosystem include salinity and ocean currents. Abiotic and biotic forces interact to form a distinct ecosystem. Abiotic influences are found in all non-living components of an ecosystem.

They are often made up of both physical and chemical components. Abiotic factors are nonliving components of an ecosystem that influence the environment. Temperature, light, and water are among the examples. Abiotic elements in a marine ecosystem include salinity and ocean currents.

Answer:

The answer is the last one, "Monitor heart rate and breathing every five minutes".

Explanation:

Because it can determine when the patient will be going into shock.

The steps that should be taken to treat a patient suspected of going into shock are: Cover the patient with a blanket and monitor heart rate and breathing every five minutes.

Covering the patient with a blanket helps maintain their body temperature, as shock can lead to a drop in body temperature due to poor blood circulation and reduced oxygen supply to tissues. This simple measure can help prevent hypothermia and provide comfort to the patient during emergency care. Monitoring the patient's heart rate and breathing every five minutes is essential to assess their condition and detect any signs of deterioration.

Shock can lead to rapid and weak pulse, as well as shallow and irregular breathing. Regularly monitoring these vital signs allows medical professionals to identify early signs of worsening shock or other critical changes in the patient's condition. Prompt recognition of these changes can lead to timely intervention and improved outcomes for the patient.

Answer:

B . Females produce fewer gametes.

Explanation:

The option that correctly describes a difference between the male and female reproductive systems is B. Females produce fewer gametes.

The reproductive system is a collection of organs and tissues that work together to produce, transport, and fertilize gametes (sperm in males and eggs in females) to facilitate reproduction. In males, the reproductive system includes the testes, epididymis, vas deferens, seminal vesicles, prostate gland, and urethra.

Sperm are produced in the testes, mature and are stored in the epididymis, and then transported through the vas deferens and mixed with seminal fluid produced by the seminal vesicles and prostate gland before being ejaculated through the urethra during sexual intercourse. In females, the reproductive system includes the ovaries, fallopian tubes, uterus, cervix, and vagina.

Eggs are produced in the ovaries and are transported through the fallopian tubes, where fertilization can occur. The fertilized egg then implants in the uterus, where it can develop into a fetus. Hormones, such as estrogen and testosterone, play important roles in regulating the reproductive system and maintaining sexual characteristics.

Answer:

Water circulates in a cycle across the hydrosphere. Clouds gather water, which then falls to Earth as rain or snow. Rivers, lakes, and seas store this water. Then it evaporates back into the atmosphere, restarting the loop.

Explanation:

Answer:

The hydrosphere is the part of Earth were all the water is contained.

The atmosphere is the part of Earth were all the gases are contained.

These two are related because the hydrosphere is inside the atmosphere.

The hydrosphere goes down below sea level, because of several trenches and other holes like the Mariana trench. The hydrosphere also goes around 20 kilometres in the air because of clouds.

Answer:

2.23 days

Explanation:

Given that;

N=Noe^-kt

Where;

N= number of radioactive nuclei present at time =t

No= number of radioactive nuclei originally present

k = decay constant

t = time taken

But k = ln2/T

Where T is the half life of the radioactive nuclei

Hence;

NA= Noe^-ln2t/TA     (1)

NB= Noe^-ln2t/TB      (2)

But NA =2.44NB

2.44NB = Noe^-ln2t/TA     (3)

NB= Noe^-ln2t/TB      (4)

Divide  (3) by  (4)

2.44NB/NB = Noe^-ln2t/TA/Noe^-ln2t/TB

2.44 = e^-ln2t/TA + ln2t/TB

Taking natural logarithm of both sides

ln2.44 = -ln2t/TA + ln2t/TB

Given that TB = 1.14 days

TA= -ln2t(ln2.44 -ln2t/TB )^-1

TA= -(2.079) (0.892 - 2.079/1.14)^-1

TA = 2.23 days
