B. It is an explanation for a wide variety of natural phenomena.
C. It is plausible explanation for many natural phenomena that has not yet been fully tested.
D. Scientific theories are the most certain knowledge that can be developed in science.
E. Numerous studies, which have all tested the theory but in different ways, have all converged on the same explanation.
F. There is ample evidence supporting the explanation.
Answer:
b
Explanation:
Evolutionary theory highlights the adaptive value of within-species variability. Optimal biological and behavioral strategies differ depending on the nature of the environmental context as well as the characteristics of the organism such as age, sex, health, or physical size.
After reading the paragraph for Practice 5, what are the possible risks and drawbacks of this use of genetic engineering?
Answer:
Genetic contamination, competition with natural species, creating potential for problematic pathogens, unwanted side effects and unfavorable level of diversity.
Explanation:
The possible risks and drawbacks of the use of genetic engineering are genetic contamination, competition with natural species, creating potential for problematic pathogens, unwanted side effects and unfavorable level of diversity. These drawbacks puts pressure on the native species and due to competition with natural species, removal of natural species occurs. There are many side effects of genetic engineering species on the health and ecosystem.

Which of the following steps should be taken to
treat a patient suspected of going into shock?
Check all that apply.
Cover the patient with a blanket.
Provide food and water to the patient.
Have the patient get up and walk around.
Monitor heart rate and breathing every five
minutes
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:
Decay adds carbon to the atmosphere.
Two radioactive nuclei A and B are present in equal numbers to begin with. Three days later, there are 2.44 times as many A nuclei as there are B nuclei. The half-life of species B is 1.14 days. Find the half-life of species A (in days).
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
Why does the control of blood sugar by insulin show negative feedback?
Select one:
The release of insulin causes sugar levels to increase even more.
Sugar lowers the levels of insulin back to the normal levels.
The release of insulin brings the sugar levels back to normal.
Insulin mixes with the sugar to prevent it from damaging the cells.
Answer:
The control of blood sugar (glucose) by insulin is a good example of a negative feedback mechanism. When blood sugar rises, receptors in the body sense a change. In turn, the control center (pancreas) secretes insulin into the blood effectively lowering blood sugar levels.

Which of the following statements is true? The spongy layer doesn't have any chlorophyll. The epidermis is the main location for photosynthesis. The cuticle slows down the loss of water in a leaf. Plants can make food without chlorophyll. PLEASE HELP
Answer: the cuticle slows down the rate of water loss.
Explanation: the spongy layer contains chlorophyll although few. Photosynthesis occurs in the chloroplast.
Plants need chlorophyll because it captures sunlight which helps in the splitting of water molecule during photosynthesis ,thus they need it to manufacture their food.

phagocytes may enter the body and cause illness.
normal cells crowd out unhealthy cells.
antibodies production is increased.
Answer:
a.
Explanation:
pathogens may enter the body and cause illness.
Immune system is the one that helps to keep away the invading organisms in the body causing disease. A person who has a weakened immune system will not be able to overcome against infection because pathogens may enter the body and cause illness, i.e., option A.
What are pathogens?Pathogens are the organisms or specifically disease-causing organisms that enter the body and alter the functioning of the immune system.
These pathogens can be bacteria, viruses, etc. that can enter through food, water, air, etc.
A weakened immune system can not be able to fight with these invading pathogens and hence leads to diseases.
Thus, the correct answer is A.

Normally, the clown fish readily swims among the tentacles of the sea anemones; the parrot fish avoids them. One hypothesis for the clown fish's apparent immunity is that they slowly build a tolerance to the sea anemone's toxin. A second hypothesis is that a chemical in the mucus that coats the clown fish prevents the nematocysts from being triggered.
Required:
Draw the graphs that supports the first, but not the second, of these hypotheses.
Answer:
The correct answer is - parrot fish - high, Clown fish - high.
Explanation:
According to the first hypothesis, the clown fish developed the immunity to the sea anemone's toxin so there would be a higher number of clown fish that swims among the tentacles of the sea anemones. The parrot fish avoids them also leads to a higher number of these fishes.
The correct graph that supports the first hypothesis that says that the clown fish's developed immunity build by them slowly, a tolerance to the sea anemone's toxin from tentacles of sea anemones.
