Answer:

The Viking tubing is meant to be the cell membrane. Glucose manages to move out of the bag and into the surrounding water but starch does not. Not all substances can pass through the cell membrane; some molecules, like starch are too large. The cell membrane is called selectively permeable because of this.

If you put all of the continents together, they fit like a puzzle. If you look at mountains and match these when they are put together, mountains will be in similar places. The fossils found in Antarctica were fossils from warm climates. That could only be if all continents used to be one!

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.

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.

Keystone

Explanation: keystone

Answer: Absent a gentle breeze or mighty gale to circulate both warm and cold weather around the Earth, the planet would become a land of extremes. Areas around the Equator would become intensely hot and the poles would freeze solid. Whole ecosystems would change, and some would completely disappear.

Answer:

Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.

4. True

Explanation:

1. Not all mutations are bad! Some actually can provide people with advantages.

2. Back to number 1, yes! Some mutations can give you advantages that people would not normally have.

3. Yes! Melanin helps protect our skin from damage from UV rays from the sun. This is why people with lighter skin tend to “tan” or “burn”.

4. Yes! Mutations are often a random process. We cannot determine whether or not someone will be born with or without a mutation.

Answer:

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.

Explanation:

Answer: How does oxygen get into the bloodstream? Inside the air sacs, oxygen moves across paper-thin walls to tiny blood vessels called capillaries and into your blood. A protein called haemoglobin in the red blood cells then carries the oxygen around your body.OK Our typical red cell passes from the capillary into the venules, and then into veins. It flows back to the right side of the heart, completing the second loop of its circuit [music out]. As we saw, it then travels back to the lungs.The heart, blood and blood vessels work together to service the cells of the body. Using the network of arteries, veins and capillaries, blood carries carbon dioxide to the lungs (for exhalation) and picks up oxygen. From the small intestine, the blood gathers food nutrients and delivers them to every cell.

Answer:

Uniform dispersion.

Explanation:

The bobcats' population distribution would be a uniform dispersion because they are distributed in an area in a balanced way. That is to say, that there is space between them and that each bobcat establishes its personal space when hunting and for their daily life. As they are solitary animals, they do not live in groups and only associate with other bobcats to reproduce themselves.

Answer:

The correct answer would be - option D. perform anaerobic respiration in the absence of oxygen.

Explanation:

Yeast is a facultative anaerobic single-cell organism that can live without oxygen. If yeast cells did not get the oxygen they use anaerobic respiration to get the energy.

If the baker activates these cells and stops them to get oxygen the yeast cells have to switch to anaerobic respiration to survive and produces ethanol and releases carbon dioxide.

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)
