Which of these changes to the cell would cause the greatest reduction in the activity of catalase? A. A decrease in the concentration of hydrogen and oxygen B. An increase in the concentration of hydrogen peroxide C. A strong bonds between carbon atoms that cannot be broken D. Ionic bonds between carbon atoms and oxygen atoms

Answers

Answer 1

Answer:

A. A decrease in the concentration of hydrogen and oxygen

Explanation:

Catalase's function is to catalyze the decomposition of hydrogen peroxide (H₂O₂), which is a toxic substance for cells, into oxygen (O) and water (H₂O).

The following chemical reaction can represent the catalase enzymatic action:

2H₂O₂ + Catalase → H₂O + O₂

Due to this, as oxygen and hydrogen (H) are structurally essential for the catalase reaction, the decrease in the concentrations of these substances would also reduce the enzyme's action potential.

What is the difference between a benign tumor and a malignant tumor? View Available Hint(s)for Part A Benign tumors will not kill you; malignant tumors will. A benign tumor is a mass of essentially abnormal cells; a malignant tumor is an abnormal mass of essentially normal cells. Benign tumors do not metastasize; malignant tumors do. Benign tumors metastasize; malignant tumors do not.

Answers

Answer:

These cells can form a mass called a tumor. A tumor can be cancerous or benign. A cancerous tumor is malignant, which means that it can grow and spread to other parts of the body. A benign tumor means that the tumor can grow, but it will not spread.

What type of cell transport is shown in the figure below?
Facilitated diffusion
Active transport
Endocytosis
Simple diffusion

Answers

It would be facilitated diffusion because channel (helper) proteins are being used. It would not be active transport because ATP is not used. Also, it is not simple diffusion because channel proteins are being used. Finally, it is not endocytosis because vesicles are not seen.

The type of cell transport which is shown in the figure in question is Facilitated diffusion. The diffusion in this transport is carried out with the help of a protein such as carrier protein or channel protein. Thus, the correct option is A.

What is Facilitated diffusion?

Facilitated diffusion is a type of diffusion where the movement of solute and solvent particles takes place from the region of higher concentration to the region of lower concentration.

The cell membrane is selectively permeable in nature as it allows the movement of selected substances through it. The molecules which are impermeable such as large, charged polar molecules cannot cross the membrane on their own and hence requires a protein which facilitates their movement. Thus, for this purpose the carrier and channel proteins which are present in the membrane facilitate this diffusion of substances.

Therefore, the correct option is A.

Which statement correctly describes a chemical reaction?
A. Reactants come out of a reaction.
B. Energy is always released.
C. Bonds between atoms break and reform.
D. Products go into a reaction.

Answers

Answer:

C). Bonds between atoms break and reform.

Explanation:

A Chemical reaction is defined as the process in which the substances(two or more) interact and form new substances by rearranging the atom structure of the substances. This process primarily consists of two steps i.e. breaking of chemical bonds that exist between the atoms in the original substances and the formation of new bonds to produce the new substance. Thus, the bonds break and reform. Hence, option C is the correct answer.

The situation that is most likely to result in a mutation that is passed on to an offspring is exposure to a chemical that affects cell formation. The correct option is C.

What is mutation?

A mutation is changing or modification in the nucleic acid or DNA sequence of a person. This is a natural process that occurs due to mutagens.

Mutation can also be artificially induced to bring out changes in the gene sequences for specific reasons. An example is an aneuploidy is a condition of the presence of more or less number of chromosomes than normal. For example, there are 45 or 47 chromosomes are present.

There are different types of mutations somatic mutation occurs in the body cell and chromosomal mutation occurs in the structure of chromosome coin mutation changing the nucleotide.

Therefore, the correct option is C. exposure to a chemical that modifies cell formation.

Some insect species are resistant to pesticides. Which statement BEST explains this phenomenon? Natural selection resulted in an unfavorable variation for the insects. Because their survival depended on it, the insects developed variations that made them resistant to poisons. Random variation in the population led to a population with a favorable adaptation. Some of the insects became instantly immune when the poisons were introduced into their environment

Answers

Answer:

Random variation in the population led to a population with a favorable adaptation

Explanation:

Insecticide resistance can be defined as an evolutionary process that causes a decreased susceptibility of an insect population to a particular insecticide. The evolution of the insecticide resistance occurs by the mechanism of natural selection, where most resistant insects survive and thus pass on their acquired heritable resistance to their offspring. Moreover, the evolutionary origins of the resistance trait may be associated with different processes: 1-de novo mutations (i.e., the emergence of beneficial genetic changes in the population), 2-standing variation in the original population which is selected under the selective agent (in this case, the pesticide), 3-migration of resistant specimens originally resistant to the pesticide, and 4-even interspecific transfer (i.e., horizontal transfer between different species).
