Mechanical digestion begins in the mouth as the food is chewed. Chemical digestion involves breaking down the food into simpler nutrients that can be used by the cells. Chemical digestion begins in the mouth when food mixes with saliva. Saliva contains an enzyme (amylase) that begins the breakdown of carbohydrates.

Replication origins have ________ DNA sequences that attract _______ proteins. A. A-T rich; histone B. G-C rich; Helicase C. A-T
goldfiish [28.3K]

Answer:

C. A-T rich; initiator

Explanation:

Replication origins have A-T rich DNA sequences that attract initiator proteins.

Replication origin is the DNA sequence where replication is initiated in a genome. The replication origin sequences is rich in adenine (A) and thymine (T) bases because it is easier to break the bonds between the bases compared to the bonds between guanine and cytosine. adenine (A) and thymine (T) bases have two bonds joining them as against three bonds between guanine and cytosine

The initiator proteins recognizes  DNA sequences in the replication origin and helps to initiate DNA replication.

A C4 plant like corn or sugarcane would not thrive in a cool shady forest because of:________
Alborosie

Answer:

The correct answer is - B. lower environmental availability of CO2

Explanation:

In C4 plants they have developed a mechanism for the CO2 concentrating and leads to the lower environmental availability of CO2 for these plants, C4  to avoid photorespiration.

These plants tend to be found in drier environments with high sunlight levels and not thrive in a cool shady forest due to this mechanism that results in low availability of carbon dioxide.

The wall of the left ventricle is thicker than that of the right and the left ventricle pumps more blood than the right. Are the
Rus_ich [418]

The wall of the left ventricle is thicker than that of the right - True

The left ventricle pumps more blood than the right - False

<u>Explanation:</u>

Heart has 4 number of chambers. One among these chambers is the left ventricle. Among the four cambers of the heart, the thick one is the left ventricle. It appears below the left atrium. The left ventricle is present in the bottom left part of the heart. When the contraction of heart occurs the blood from the valve called mitral enters the left atrium from the left atrium.  

The left ventricle transports the oxygenated blood to the human body. The left ventricle needs along these things for pumping the blood. The right ventricle can function by itself and is more powerful than left ventricle. The right ventricle is responsible in pumping blood to the lungs on its own.

According to the central dogma, which of the following represents the flow of genetic information in cells?
const2013 [10]

Answer:

DNA to RNA to protein.

Explanation:

Central dogma in biology was given by Crick in 1957. The central dogma explains the flow of genetic information in the cells.

According to the central dogma, DNA can multiply and increase its number by the process of replication. The information from DNA is changes to RNA by the process of transcription. The expression of protein product expression occur from the RNA by the process of translation. Hence, the information travels from DNA to RNA to protein.

Thus, the correct answer is option (2).

10 pounds of walnuts cost $50. How much does 1 pound of walnuts cost?
valentina_108 [34]

Answer:

$5 is the cost of 1 pound of walnuts

P (Pounds) = 5D (Dollars)

Explanation:

Since 10 pounds of walnuts = $50.

Let 1 pound of walnuts = Z

then, cross multiply

So, Z = ($50 X 1 pound) / 10 pounds

Z = 50/10

Z = $5

Thus, 1 pound of walnuts will cost 5 Dollars while P (Pounds) = 5D (Dollars) is the equation that shows the relationship between pounds and dollars
