Answer:

ABO blood group system, the classification of human blood based on the inherited properties of red blood cells (erythrocytes) as determined by the presence or absence of the antigens A and B, which are carried on the surface of the red cells. Persons may thus have type A, type B, type O, or type AB blood.

You are enjoying your vacation on the coast and decided to go snorkeling. Your tidal volume is 460 mL and breathing rate is 14 b

m_a_m_a [10]

Answer:

Option C

Explanation:

Option

A. 6440 mL/min

B. 4340 mL

C. 3500 mL/min

D. 2940 mL/min

Solution

It is required to find the minute ventilation which is equal to the product of rate of breathing and the total amount of gas being inhaled or exhaled per breathe. Let this minute ventilation be denoted by " $V_f$ "

Thus,

$V_f = TD * B_r$

where TD is the tidal volume and Br is the rate of breathing

Substituting the given values we get

$V_f = 460 *14 \\V_f = 6440$

We will now reduce the air held in the conducting zone of respiratory system

Air held per breathe $= 210$

Total Air held

$= 210 * 14 \\= 2940$

Amount of fresh air one can breathe in and out every minute

$= 6440 - 2940 \\= 3500$

Hence, Option C is correct

Why factors are cause of short-term climate change

laiz [17]

Answer:

6 factors that cause short term climate change...

Explanation:

Latitude - depends on how far or close to the equator it is

Ocean currents - Certain ocean currents have different temperatures.

Wind and air masses. Heated ground causes air to rise which results in lower air pressure. As it rises it cools and descends to the ground resulting in high air pressure.

Elevation. The higher up you are, the colder and drier it will be. When air rises it expands due to low air pressure which causes it to cool.

Relief. The differences in the elevation inland. As air is forced to rise over a piece of land, the temperature decreases and condensation increases.

Nearness to water. The water heats up and cools down slower than land does, having a moderating effect. On colder days, the water heats up the land, whereas on hotter days, the land is cooled down by the water.

What is plant blindness?

Komok [63]

Answer:

The answer is A.

Explanation:

Plant blindness refers to "the inability to see or notice the plants in one's own environment." The term plant blindness was coined twenty years ago by Elizabeth Schussler and James Wandersee who are botanists. Plant blindness results in "the inability to recognize the importance of plants in the biosphere and in human affairs." It is also the reason why people have a tendency of ranking “plants as inferior to animals”. Therefore, plants tend to receive limited care and upkeep. It is important to recognize plant blindness so that more intentional care can be given to preserving our plant species and ensure their survival and ability to thrive.

Some geneticists study the genes that control bone development to try to understand bone growth and find cures for diseases. How

AnnZ [28]

Options:

a) the geneticist looks at the symptoms of a disease, and the orthopedist does not.

b) the geneticist works in a hospital, and the orthopedist works in a lab.

c) the geneticist focuses on what causes the disease, and the orthopedist treats the disease.

d) the geneticist deals with patients, and the orthopedist does not.

Answer:

The geneticist focuses on what causes the disease, and the orthopedist treats the disease. so thats why different from an orthopedist (a doctor who specializes in bones). Thus, the correct option is C.

<h3>What is chromosomes?</h3>

A chromosome is a lengthy DNA molecule that contains all or a portion of an organism's genetic code. Histones, which serve as packing proteins for the majority of eukaryotic chromosomes, work with chaperone proteins to attach to and condense the DNA molecule in order to preserve the integrity of the molecule.

A medical geneticist specializes in using DNA tests and genetic data to identify, manage, or prevent chromosome problems, inherited genetic illnesses, and other genetically driven diseases and ailments.

Orthopedic physicians, often known as orthopedic surgeons, concentrate on assisting you with musculoskeletal problems. They are responsible for identifying and managing diseases that impact your musculoskeletal system.
