Answer:
What's more, genetic evidence has shown that modern humans mated with Neanderthals before these individuals disappeared about 40,000 years ago. Many of us today still have 1 to 2 percent Neanderthal DNA, findings that suggest that modern humans who encountered these individuals saw them as people, too.

In corn, seeds may be starchy (S) or sweet (s). Cross two heterozygous starchy corn plants. Using a Punnett’s square, give the phenotypic ratio then state the proportion of offspring that would be expected to be sweet?
Answers
if we cross Ss with Ss on the punnet square we will get the gametes S and s for both parents
on top left we have SS since we combine the alleles S and S
on top right we have Ss since we combine the alleles S and s
on bottom left we have Ss since we combine the alleles S and s
on bottom right we have ss since we combine the alleles s and s
The phenotypic ratio starchy:sweet is 3:1
1:3 of the offspring will be sweet

HELP ASAP PLEASE!! DUE IN 10 MINUTES !!! based on these results which statement correctly predicts what will happen to red blood cells when they are placed in a beaker containing a water solution in which the salt concentration is much higher than the salt concentration in the red blood cells
A:the red blood cells will absorb water and increase in size
B:the red blood cells will lose water and decrease in size
C:red blood cells will of first absorb water than lose water and maintain their normal size
D:the red blood cells will first lose water then absorb water and finally double in size
Answers
Answer:
The correct answer is - option B. the red blood cells will lose water and decrease in size.
Explanation:
The movement of the water takes place always from the high concentration region of solute to the low concentration of solute through a semi-permeable membrane. In this case, the representation is showing that placing the cell inside a solution with low concentration solute than the cell makes the cell increase the size, and placing it in a solution high concentration of solute makes it decrease in size due to the transfer of water from more water to the low water area.
Now placing the RBC in a solution with more salt concentration than the cell makes the solution hypertonic which means the solution has more solute concentration and less water so the water move from cell to the solution and cell will shrink and decrease in size.

Explanation:
Another name for antidiuretic hormone (ADH) is arginine vasopressin.
It is made by the hypothalamus in the brain.
It is stored in the posterior pituitary gland.

What is true about cellular respiration?
Answers
Answer:
Cellular respiration can occur both aerobically (using oxygen), or anaerobically (without oxygen). During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts.

Explanation:
Hoped my answer was right and it helped you!!! Best of luck :D
also heres this
Disruptive selection, also called diversifying selection, describes changes in population genetics in which extreme values for a trait are favored over intermediate values. In this case, the variance of the trait increases and the population is divided into two distinct groups.
Stabilizing selection (not to be confused with negative or purifying selection) is a type of natural selection in which the population mean stabilizes on a particular non-extreme trait value. ... This means that most common phenotype in the population is selected for and continues to dominate in future generations.
directional selection: a mode of natural selection in which a single phenotype is favored, causing the allele frequency to continuously shift in one direction. disruptive selection: (or diversifying selection) a mode of natural selection in which extreme values for a trait are favored over intermediate values.

Provide at least three reasons why friction is needed.
Answers
Answer:
Although you normally hear about trying to reduce or eliminate friction, it actually has some important uses.
Since friction is a resistance force that slows down or prevents motion, it is necessary in many applications where you might want to hold items or do things and prevent slipping or sliding. In those cases, there is an advantage of having friction.
Quite often uses of frction can be seen from how things would be without friction. Without friction, you would not be able to walk, drive a car, or hold objects. Pens and pencils would not work.
Explanation:
Answer:
Friction allows people and objects to move. It provides traction for an object to start moving or change direction. It can also give people a better grip on objects. Finally, friction keeps objects in place when they are set down.

Answers
Answer:
Light energy is converted to chemical energy.
Please find the explanation below
Explanation:
Photosynthesis is a unique process that occurs in the cells of green plants and other autotrophic organisms. It is the process whereby they synthesize their food in form of carbohydrates (sugars). The photosynthetic process takes place in two stages namely: light dependent reaction and light-independent reactions.
The light dependent reaction or simply light reaction is the stage where light energy from the sun is harnessed by a pigment called CHLOROPHYLL and used to produce ATP needed to build glucose molecules in the next stage. Hence, via this process, the LIGHT ENERGY from the sun is converted to CHEMICAL ENERGY in ATP.
