Species A has the best chance of survival because it has the most genetic diversity.

Genetic diversity is defined as the set of different inherited traits that occurs within a species. Those organisms having higher genetic diversity have more chances of survival.

So we can conclude that Species A has the best chance of survival because it has the most genetic diversity.

Explanation:

It was designed to determine whether the genetic material of the bacteriophage (a type of virus that infects bacteria) is made of DNA or protein.

The Hershey-Chase experiment, also known as the "Blender Experiment," was a classic experiment in molecular biology that was conducted in 1952 by Alfred Hershey and Martha Chase. It was designed to determine whether the genetic material of the bacteriophage (a type of virus that infects bacteria) is made of DNA or protein.

In the experiment, components of the bacteriophage were labeled with radioactive isotopes of sulfur and phosphorus. The labeled phages were then used to infect bacterial cells, and the cells were subjected to various treatments to separate the viral components from the bacterial components.

The results of the experiment showed that the genetic material of the bacteriophage was made of DNA, not protein. This was determined by the fact that the labeled DNA, but not the labeled protein, was able to enter the bacterial cells and infect them. This experiment provided strong evidence for the "central dogma" of molecular biology, which states that genetic information flows from DNA to protein, but not the other way around.

Answer:

1. 10% 2. 90% 3. 80% 2. Yes 3. Into 3. Swell 6. Hypotonic

Explanation:

1. Given the image, it shows there is 10% glucose outside the cell.

2. Because there is 10% glucose outside the cell, you can automatically conclude that there is 90% of water outside. (You want it to equal to 100%. So, 10 + 90 = 100)

3. Given 20% glucose inside the cell based on the image, you can conclude that there is 80% water inside the cell.

2. Yes, osmosis will occur. Osmosis is the movement of water from a higher concentration to a lower concentration. In this case, there is more water outside the cell than in. So, yes, osmosis will occur.

3. The water will move into the cell (There's less water inside, and more outside, so of course, the water will move in).

3. The cell will swell, since water is getting moved in.

6. This is a hypotonic solution. Definition of a hypotonic solution: The concentration of solutes outside the cell is less than that of water. Hypotonic solutions always swell, as water moves into it.

Siblings look different cause of the genetics combining through child creation

Explanation:

Answer:

DNA is a self replicated material that is inside almost every living animal, and human being. DNA contains genetic codes. Dna holds genes, for example those who created you, there genes are passed on to you causing it to also be in ur DNA. It contains instructions that an organism needs to live, develope and reproduce. DNA serves as the primary unit of heredity in different types of organisms. (It might not be long enough but maybe this could atleast be used as half a paragraph)

Answer: Function. Vitamin A helps form and maintain healthy teeth, skeletal and soft tissue, mucus membranes, and skin. It is also known as retinol because it produces the pigments in the retina of the eye. Vitamin A promotes good eyesight, especially in low light. Vitamin A (retinol) is ingested as either retinyl esters or carotenoids and metabolized to active compounds such as 11-cis-retinal, which is important for vision, and all-trans-retinoic acid, which is the primary mediator of biological actions of vitamin A

Explanation:

Sound waves propagate from the sound source. The sound through radio comes through the electrical signal, radio wave, and sound wave. Thus, option D is correct.

A sound wave is an acoustic wave that travels through a medium through the disturbance of the particles in a longitudinal direction. A few examples are radio, whisper, rustling, etc.  

The sound waves in radio first get converted into the electrical signal that passes through the circuit of the radio that further gets transferred as radio waves.

These radio waves are the part of the electromagnetic spectrum that travels at a little less speed than light. The radio waves again get converted into sound waves as it leaves the system and reaches the ear of the organism.

Therefore, option D. sound wave → electrical signal → radio wave → sound wave is the correct order.

Answer:

if the foliation on a rock is running north-south, the pressure might be vertical (for instance, up to down)

Explanation:

The pressure is the second most principal factor that influences metamorphic rocks. It originates from the weight of the own materials, their densities, and the deepness.  

Litostatic pressure originates from the weight of materials in the interior of the crust.

Pressure generates alignment of materials (foliation and schistosity) and mineral rotation.

There are different types of metamorphism.

Dynamic metamorphism is the one where pressure is the principal factor. It generates by tectonic conditions, and it presents mainly in failure or fracture areas. It provokes trituration and recrystallization of minerals.

Classification of the metamorphic rocks according to their structure:

Foliation refers to dynamic metamorphism, where pressures act and minerals orientate perpendicular to the pressure direction.

According to this concept, if the foliation on a rock is running north-south, the pressure might be vertical (for instance, up to down) while minerals' weight helping in the process of foliation.

If the foliation on a rock is running north-south, the tectonic pressure is coming from a vertical direction.

Foliation on a rock means continuous multi layering on a metamorphic rock.

These layers can be thin as a sheet of paper.

Foliation occurs when the plain or elongated minerals inside a rock are pressed together and aligned.

Thus, If the foliation on a rock is running north-south, the tectonic pressure is coming from a vertical direction.
