The best experimental design:______
a. alters only one condition between the controls and the experimental condition
b. includes a large sample size for each condition
c. includes a control

Answers

Answer 1

Answer:

The correct answer is option d. "includes a large sample size and a control, and alters only one condition between the controls and the experimental condition".

Explanation:

The correct answer for this question is missing, which is option d. "includes a large sample size and a control, and alters only one condition between the controls and the experimental condition". The best experimental design includes all the options proposed: it includes a large sample size to ensure that the data is statistically relevant; a control to verify that the results are valid and are not obtained from other untested conditions; and it alters only one condition at the time to ensure the existence of the relation between condition and results.

How digestive enzyme affected when people having high fever? Explain.

Answers

Higher the body temperature, it would disrupt the shape of the active site of the enzyme , which will reduce its activity, or prevent it from working. The enzyme will have been denatured also the protein which can also lead to death.

Answer:

When a person has high fever, it's body temperature increases.

When the temperature is too high, enzyme molecules vibrate vigorously causing it to lost it's shapes and active sites.

Then, started to denatured and eventually, the enzyme died and no longer able to function.

Which of followings are true?

a. Most people accept that the characteristics within a population--say pesticide resistance in lice--can change over time.
b. Some refer to the theory of evolution as "just a theory" with other competing and equally likely alternatives.
c. Some people want "special creation"--the idea that living things were created by a supernatural agent--to be considered as an alternative hypothesis alongside the theory of evolution in science education.
d. Science has rejected a hypothesis that different groups of organisms can show relationships without sharing one common ancestor.
e. Fossils are the direct evidence we have to test the theory of evolution.
f. The theory of evolution is accepted by scientists as the correct explanation for the origin of humans.

Answers

Answer:

A) True

John Marshall Clark a pesticide toxicologist recently discovered in one his studies at the University of Massachusetts that about 67% to 75% of lice are no longer affected adversly by insecticides.

B) True

An alternative to the theory of evolution is the Theistic Evolution.

C) True

Creationism or Special Creation is one of the ideas of evolutions which tries to offer a better explanation to the origin of the universe.

D) False

An example would be the winds of Bees, Bats and Birds. They all use wings (with similar structure) to fly however, their origins as explained by evolution are quite different taking into conginsance how they are formed at the embryo stage.

E) True

To understand evolution, we have to study and obtain as much as possible, all the information that a fossil can provide. Many times, these information provide substantial elements which support the theory.

F) False

Evolution is a theory which scientists have accepted as ONE of the several explanations of the origins of the human species. There are other competing theories.

Which species is likely to exhibit random dispersion?
A.
rushes that grow on the edges of bodies of water
B.
orchid plants that grow on the branches of a particular tree species
C.
squirrels that actively defend their territory against other squirrels
D.
frogs that live along the edges of ponds and streams
E.
sweetgum, a tree species with wind-dispersed seeds

Answers

Answer:

E

Explanation:

E because....

The other options mention species that occupy niche environments and would therefore definitely not be randomly dispersed. Rushes and frogs would be found along the edges of water bodies, squirrels would be found within appropriate environments, which would be acorn tree forests and orchid plants also occupy a particular tree.

The correct option is E.

What is random dispersion?

In random dispersion, individuals are distributed randomly, without a predictable pattern. An example of random dispersion comes from dandelions and other plants that have wind-dispersed seeds.

Is random dispersion rare?

In natural populations, random dispersion is rare, while clumped dispersion, which we'll focus on in this lesson, is the most common pattern. Clumped dispersion is often due to an uneven distribution of nutrients or other resources in the environment. It can also be caused by social interactions between individuals.

C. The segment of DNA that is damaged is transcribed into RNA.
D. The nucleotide sequence of the damaged DNA is restored

Answers

Answer:

B.an error occurs when the damaged DNA is repairex

Explanation:

the best answer is B

The damaged DNA can lead to a mutation represent that option b. An error occurs when the damaged DNA is repaired.

Reason for damaged DNA?

In the case when the DNA is damaged so it should be replicated that shows an incorrect base which should be inserted opposite the site of the damaged base in the strand i.e. complementary.

Due to this, it should become the mutation at the coming replication round.

Moreover, the double-strand DNA split might be repaired.

Hence, the option b is correct.

SCENARIO ABiological anthropologists have discovered a previously unknown fossil species namedAustralopithecus sediba. The species lived about 2 million years ago in Africa and has an interesting mix of traits. For example, its arms are adapted for climbing in trees and its legs are adapted for walking on two legs on the ground. It does not directly resemble any of the living ape species, which suggests that the living ape species (including humans) have each become adapted for their own environmental contexts over time.What is the primary type of biological anthropology addressed in this research?A.

Given structure is that of a virus, which includes the viral capsid, nucleic acid, etc.

A= spike

D= Capsid

What are Viruses?

Small infectious agents known as viruses can multiply only in the living cells of other animals. They are composed of genetic material, which can be DNA or RNA, encased in a protein shell called a capsid. Some viruses also have a lipid-based outer coat.

Because they cannot perform metabolic functions on their own and require a host cell to reproduce, viruses are not considered living organisms. They spread infection to various living things including bacteria, plants, animals and people.

A virus replicates its genetic material and forms new viral particles when it infects a host cell using the host cell's machinery. This can lead to the death of the host cell and result in the spread of the virus to other cells of the host.

Therefore, given structure is that of a virus, which includes the viral capsid, nucleic acid, etc.

Which of the following statements is true regarding anabolism?

Choose 1 answer:

А) Energy is released during anabolic reactions.
B) In anabolism, larger molecules are made from smaller molecules.
C) Anabolism is the sum of all the chemical reactions in a cell.
D) Anabolism uses the process of hydrolysis to join molecules together.

Answers

Answer:

B) In anabolism, larger molecules are made from smaller molecules.

Explanation:

Anabolism is a metabolic process that uses up energy that is produced to build up complex and larger molecules from smaller ones. It is part of the chemical process that takes place in a cell.

For example, photosynthesis is an anabolic process, in which the cell forms larger molecules such as glucose from smaller molecules like water and carbon dioxide, with the use of solar energy.

Option B is true regarding anabolism.

What is aquarium?

Aquarium is defined as any size tank with at least one transparent side used to house and display aquatic plants and animals. Like zoos, aquariums offer enjoyable leisure and amusement activities that also serve as locations for scientific research, education, animal care, and conservation.

Your fish may die if there are any significant temperature variations in their tank. Do not place your tank close to cooling vents or in a location that gets a lot of sunlight. A steady water temperature of 72°F to 82°F is required for freshwater fish, while 75°F to 80°F is ideal for saltwater fish.

Thus, some of the energy in the system has moved from one organism to another during the 3 months. Hence option E is correct.
