what experiments led to the discovery of dna as the hereditary material?

Answers

Answer:

In the 1920s, Frederick Griffith He was studying two different strains of a bacterium, called R (rough) strain and S (smooth) strain. He injected the two strains into mice. The S strain killed (virulent) the mice, but the R strain did not (non-virulent). Griffith also injected mice with S-strain bacteria that had been killed by heat. As expected, the killed bacteria did not harm the mice. However, when the dead S-strain bacteria were mixed with live R-strain bacteria and injected, the mice died.

Which nitrogenous base is NOT found in RNA?
1 Adenine
2 Cytosine
3 Guanine
4 Thymine
5 Uracil

Answers

Uracil is a nitrogenous base found in all RNA but not present in DNA. There are multiple unusual modified bases found in tRNAs not found in DNA as well: Dihydrouridine, Pseudouridine, 1-methyl adenosine, N2,N2-dimethylguanosine, inosine, and 1-methyl-inosine. There are other nitrogenous bases that are metabolic intermediates that are not found in nucleic acids such as inosine (also in tarna), hypoxanthine, xanthine, dihydroorotate, orotate, and the purine break down product uric acid.

The abundance of sodium leak channels in skeletal muscle is ______ the abundance of sodium leak channels in a typical neuron.

Answers

The abundance of sodium channels in muscles is as important as the abundance of sodium leak channels in a typical neuron.

Sodium plays an essential role in the body, this includes important functions such as:

Intervening in the process of muscular contraction.Intervening in the process of interneural communication.

This is possible through sodium channels in cells that allow sodium to enter or leave the cell at very specific times and this causes specific reactions in cells.

In neurons: Sodium channels are abundant and essential because due to the action of sodium signals are passed from one neuron to others.In muscles: Sodium channels are abundant and essential, especially in skeletal muscles. The role is sodium is to contract or relax muscles, which makes movement possible.

Based on this, the presence of these channels in both neurons and skeletal muscles is equally important.

Explain how homologous structures are used as a source of evidence to infer evolutionary relationships between modern and fossil organisms

Answers

Answer:

Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations.

Explanation:

Analogous structures demonstrate that identical selective pressures might result in similar adaptations, whereas homologous structures indicate evidence for shared ancestry.

What are analogous structures?

In contrast to homologous structures, analogous structures are characteristics of different species that have evolved in response to a similar environmental challenge and are similar in function but not necessarily in structure.

While comparable structures demonstrate that similar selective pressures can result in similar adaptations, homologous structures suggest that they have a common ancestor (beneficial features).

Therefore, homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations.

function of nucleus, mitochondria ,endoplasmic reticulum, vacuoles ​

Answers

Answer:

nucleus...controls all the activities of the cell and carrries the genes

mitochondria..site for respiration that yields energy for the cell

endoplasmic reticulum... protein synthesis and lipids metabolism

vacuoles.... handle waste products and are responsible for regulation of osmotic pressure of a cell also

Explanation:

is this helpful?

The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information.

Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions.

A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products.

The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function.

Why is air temperature above land warmer than the air temperature above water in the same location during the summer?

Answers

Answer:

Sea breezes happen during the hot, summer days due t the unequal heating rate of land and water

Explanation:

Solar heating of the Earth’s surface is uneven because land heats faster than water, and this causes air to warm, expand and rise over land while it cools and sinks over the cooler water surfaces.

Under which conditions would air hold less water vapor than it holds at 30°C
(86°F) with sunny skies?
A. 34°C (94°F) with cloudy skies
B. 30°C (86°F) with cloudy skies
C. 22°C (86°F) with sunny skies
D. 32°C (90°F) with sunny skies

Answers

Answer:

B

Explanation:

jus CS its right

The relative humidity of the air affects how much water vapor it can hold. 30°C (86°F) with cloudy skies would air hold less water vapor than it holds at 30°C (86°F) with sunny skies. So, the correct option is B.

What is Relative humidity?

Relative humidity (RH) measures the amount of moisture in the air compared to the maximum amount of moisture in the air at a given temperature and pressure. It is a standard figure for describing the moisture content of the air and is expressed as a percentage.

At a given temperature and pressure, air is considered to have 100% relative humidity when it contains all the moisture it can hold. The temperature at which the moisture in the air begins to condense into droplets is known as the dew point.

Therefore, the correct option is B.

exchange of gases in the human breathing system takes place in the?​

Answers

Answer

alveoli

Explanation

During gas exchange oxygen moves from the lungs to the bloodstream. ... This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.

Required Answer :-

The exchange of gases takes place in the alveoli.

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

Additional information :-

Alveoli are microscopic air sacs.

They are the primary sites of exchange of gases. Gas exchange also occurs in lungs and tissues by diffusion.

Atmospheric air contains little CO2, but blood flowing in pulmonary capillaries has a higher concentration of CO2.

CO2 diffuses from higher concentration in blood across walls of alveolar capillaries to lower concentration in air in alveoli.

Blood coming into pulmonary capillaries is oxygen poor and alveolar air is oxygen rich.

Oxygen diffuses from higher concentration in alveoli across walls of alveolar capillaries to lower concentration in blood.
