PLEASE HELP!Why Is A Buffer Only Effective Within A Certain PH Range?

Answers

Answer 1

Answer:

A concentrated buffer can neutralize more added acid or base than a dilute buffer, because it contains more acid/conjugate base. However, any buffer will lose its effectiveness if too much strong acid or base is added.

normal cells crowd out unhealthy cells.
antibodies production is increased.

Answers

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.

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.

When part of the mushroom is damaged by an insect larvae bite, it will release a chemical that is poisonous. The chemical prevents the larvae from maturing into an adult. Some individual mushrooms of this species produce stronger chemicals that are more effective.

Which of the following best describes the type of mushroom that is more likely to survive and reproduce?
A.
Mushrooms that have the trait of attracting more insect larvae are able to spread their offspring further.
B.
Mushrooms that have the trait of producing stronger poisonous chemical have less energy for growth.
C.
Mushrooms that have the trait of producing stronger poisonous chemicals are better able to deter predators.
D.
Mushrooms that have the trait of attracting more insect larvae can get more food and nutrients.

Answers

Answer:

The answer is C

Explanation:

The correct answer is that mushrooms that have the trait of producing stronger poisonous chemicals are better able to deter predators and are more likely to survive and reproduce, which is Option c.

What is a mushroom?

The ability of a mushroom to produce a poisonous chemical when damaged by an insect larva bite is a type of chemical defense mechanism that many organisms use to deter predators. This chemical defense mechanism helps the mushroom protect itself from further damage by deterring the insect larva from feeding on it or from maturing into an adult. Individual mushrooms of this species that produce stronger chemicals that are more effective will be better able to deter predators and are therefore more likely to survive and reproduce.

Hence, the correct answer is that mushrooms that have the trait of producing stronger poisonous chemicals are better able to deter predators and are more likely to survive and reproduce, which is Option c.

this is science, please put a short desrciption for each of the sun's layers. ​

Answers

Answer: The core is the only place where nuclear fusion reactions can happen. In this broad zone, heat from the core cools dramatically, from between seven million K to two million K. Convection continues to be efficient in transporting heat until layers are reached where the density is so low that radiation from the hot up-flowing gas can escape directly into space. The lowest layer of the sun's atmosphere is the photosphere. It is about 300 miles (500 kilometers) thick. This layer is where the sun's energy is released as light. At other times, light from the chromosphere is usually too weak to be seen against the brighter photosphere. The chromosphere may play a role in conducting heat from the interior of the sun to its outermost layer, the corona. The corona is the outer atmosphere of the Sun. It extends many thousands of kilometers (miles) above the visible "surface" of the Sun, gradually transforming into the solar wind that flows outward through our solar system.

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.

Answers

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.

What happens when the most
limiting factor in an ecosystem is
removed?

Answers

The answer is A, population growth increases .

—Explanation—
•] The definition of limiting factor; anything that constrains a population's size and slows or stops it from growing.
•]Some examples of limiting factors are biotic, like food, mates, and competition with other organisms for resources.
•] So if the limiting factor is removed then the population begins to expand due to not having a factor that limits each species quantity.

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).

Answers

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
