6. Samples of atmospheric air and exhaled air were analysed by four groups
of students for oxygen and carbon (IV) oxide content. The following are
the results, expressed in volumes per thousand:
(i) Amount of oxygen in atmosphere = 200
(ii) Amount of oxygen in exhaled air = 160
(iii) Amount of carbon (IV) oxide in atmosphere = 300
(iv) Amount of carbon (IV) oxide in exhaled air =41
Explain the difference in volume of each gas between the atmosphere and
the exhaled air.​

Answers

Answer 1

Answer:

Due to difference in volume of both atmosphere.

Explanation:

There is difference in volume of carbondioxide and oxygen gas between the atmosphere and  the exhaled air because of the volume difference of atmosphere and exhaled air. The volume of atmosphere is larger than the body from where the gases are exhaled. The body has lower space for these gases so these gases are less in concentration in the exhaled air which the body releases as compared to the atmosphere where the concentration of these gases are larger.

An organism has 2 chromosomes in its cells (the diploid number is 2). Calculate the number of chromosomes in a cell in the 5th generation if egg and sperm cells were diploid

Answers

Answer:

64

Explanation:

Since the cell has two chromosomes and a diploid number of 2, in each generation, the cell doubles. In the first generation, we have two cells, in the second generation, we have 2 × 2 cells ,in the third generation, we have 2 × 2 × 2 cells. It follows that we have 2ⁿ cells in each generation where n represents the generation.

So, in the fifth generation, n = 5, so the number of cells is 2⁵ =  32.

Since we have 2 chromosomes in each cell, the number of chromosomes in the 32 cells in the 5th generation is 2 × 32 = 64 chromosomes.

Some human white blood cells help destroy pathogenic bacteria by *
(1) causing mutations in the bacteria
(2) engulfing and digesting the bacteria
(3) producing toxins that compete with bacterial toxins
O (4) inserting part of their DNA into the bacterial cells

Answers

Answer:

2

Explanation:

They either engulfy and digest pathogens(phagocytosis) or produces antibodies.

Some human white blood cells help destroy pathogenic bacteria by engulfing and digesting the bacteria. The correct option is B.

Thus, By engulfing pathogenic bacteria through a process known as phagocytosis, some human white blood cells, notably phagocytes like neutrophils and macrophages, aid in the destruction of pathogenic germs.

These phagocytes have the capacity to identify and bind to bacteria, creating a phagosome—a membrane-bound compartment—around the bacterium.

The phagosome then joins forces with lysosomes, which are organelles that carry digesting enzymes, to create a phagolysosome. The bacteria are exposed to the lysosomal enzymes inside the phagolysosome, which causes them to break down and die.

Thus, Some human white blood cells help destroy pathogenic bacteria by engulfing and digesting the bacteria. The correct option is B.

What process is responsible for satisfying the third tenet of the Cell Theory, which states that new cells originate from other living cells?

Answers

Answer:

Cell division

Explanation:

Everything starts from the union of a sperm and an egg, which gives rise to a cell, which has to become an adult organism. For this, this cell divides in such a way that in each division exactly the same genetic information is maintained. The cell is the reproductive unit of living beings. Throughout its life the cells are nourished and increase in size. When a cell reaches the appropriate size, it usually gives rise to two cells similar to the original cell. Cell Theory is one of the fundamental bases of biology and it is where the base of the constitution of living beings and the fundamental role of cells in them is summarized. It is formulated in the first place thanks to observations and formulations of Theodor Schwann ( physiologist) and Matthias Schleiden (botanist).The current third principle of cell theory, formulates that a cell comes from another cell, by cell division or by formation from stem cells. The oldest and most primitive cells in the world are prokaryotes (without a cell nucleus).

Epinephrine initiates a signal transduction pathway that involves the production of cyclic AMP (cAMP) and leads to the breakdown of glycogen to glucose, a major source of energy for cells. But glycogen breakdown is only part of the fight-or-flight response that epinephrine brings about; the overall effect on the body includes increased heart rate and alertness, as well as a burst of energy. Given that caffeine blocks the activity of cAMP phosphodiesterase, propose a mechanism by which caffeine ingestion leads to heightened alertness and sleeplessness.

When H. pylori was first discovered, researchers doubted the finding. It was thought that the acidic environment of the stomach was too hostile for microbes to thrive. Newer research using genetic analysis and culture techniques has revealed that there is a diverse gastric microbiota. Of the options below, what is the only one that does not involve genetic analyses?
A. Sequencing approaches have shown that the normal microbiota includes Archaea and provide mechanisms for studying their distribution.
B. Knowledge of growth rates allows researchers to predict responses to changing conditions.
C. Knowledge of the microbiota from sequencing efforts has been used to improve cultivation techniques.
D. Genetic analyses have been used to examine the dominant species in different individuals, showing that it varies from one individual to another.

Answers

Answer:

B. Knowledge of growth rates allows researchers to predict responses to changing conditions.

Explanation:

Genetic analyzes are tests that try to identify the genetic composition of a living being, being able to analyze the DNA in a profound way and obtaining crucial information about the organism. The most common way to carry out a genetic analysis is through the sequencing of genes, since they are segments of DNA molecules. Therefore, we can conclude that among all the response options presented above, all that refer to the sequencing of genes should be discarded. Thus, we can see that option B is the correct option, since the analysis of growth rates does not involve a genetic analysis.
