Answers
Answer:
Thrust and Lift.
Method:
There are 4 forces acting upon a plane while it is moving. Drag (The air friction while it's in the air), Lift (Generated by the wings (The upward force), Weight (How heavy the plane is), and finally, Thrust (Generated by the engines which moves the plane/wings through the air generating lift). If there is enough air going over the wing at a high enough speed, and Thrust, and Lift overcome the other two forces keeping the plane on the ground, it can fly. The air pressure under the wing is higher than over the wing - If you have ever ran you hand under the water keeping it flat, you may notice it going up, those are basically the same forces, but under water.
How does the pressure under the wing affect the lift?
The difference of air pressure over the wing (which is less), which also means less force bringing the plane down. The air pressure under the wing is higher, putting pressure on the wing moving it up. A wing is designed to make the air travel a longer distance over the wing than under the wing creating the air pressure. The engines just enforce that process.

How do the
populations in a community depend on
each other?
Answers
There are many distinct ways in which populations in a community are interdependent, and these interdependencies form the cornerstone of the intricate interactions that exist between various species in an ecosystem.
What is population?A population is a collection of people belonging to the same species who coexist and communicate in a certain geographical region. Depending on the species and the habitat it lives in, a population can have anything from a few to millions of members.
Examples of how different groups in a society are interdependent include:
Food webs and chains: In a community, many creatures rely on other organisms for nourishment. For instance, plants are the main providers of the food that feeds herbivores, which are then consumed by carnivores. A food web is formed by the links between several food chains, which is a network of energy flow.
Pollination: To enable fertilization and the development of seeds, many plants rely on pollinators like bees, butterflies, and birds to move pollen from one plant to another.
Decomposition: species that break down dead organic materials, such as bacteria and fungus, recycle nutrients and make them accessible to other species in the ecosystem.
Competition: Within a community, populations may clash for resources like food, water, and space. This rivalry may restrict population expansion and have an impact on how species are distributed throughout an ecosystem.
Symbiotic interactions: In a community where two or more species coexist and are dependent on one another for existence, there are symbiotic interactions between the many populations that make up that community.

If these three materials all come into contact at once, which direction will thermal energy
flow?
A. O from A to both B and C
B. O from B to both A and C
C. O from both A and B to C
D. Ofrom C to both A and B
Answers
Answer:
C. O from both A and B to C
Explanation:
Thermal energy is the energy derived from heat. Ideally, thermal energy will flow from a hotter region to a colder or less hot region. According to the image depicted in this question, three materials of differing temperature values are shown.
If these three materials all come into contact at once, thermal energy will flow via conduction, from the hottest to the coldest. Since materials A and B are of the same temperature value, which is higher than that of material C, THERMAL ENERGY WILL FLOW FROM BOTH A and B (hottest) to C (coldest).
N.B: The temperature reading is indicated in the image. The higher the value on the scale, the higher the temperature.

The image represents the continental-continental boundary. When two continental plates collide, that's another kind of convergent plate boundary. The continental lithosphere is very thick and has a low density. The continental lithosphere cannot subduct. So when two mainland plates impact, they simply crush together.
Plate tectonic boundaries come in three varieties: plate boundaries that are transformed, divergent, and convergent. The three primary types of plate boundaries are depicted in this image: transform, convergent and divergent.

A breeder crossed two chickens, one is a true-breeding black chicken and the other is a true-breeding yellow chicken. All the resulting F1 chicks are black. Several of these F1 black chicks are crossed with the following results: 43 black, 14 brown, and 19 yellow chicks. What kind of inheritance is this? Friend #1 tells you that the answer is incomplete dominance but Friend #2 tells you that the answer is epistasis. You analyze the problem and realize that neither is right. The problem is a trick problem and there is no answer to it.
Answers
Answer:
You analyze the problem and realize that neither is right
Explanation:
All intersections and proportions are attached.
First, let's analyze the crossover that formed the F1 generation. At this crossing, chickens of genuine color were used, which indicates that one of them was h0m0zygous recessive (aa) and h0m0zygous dominant (AA). Thus, the entire offspring would be heterozygous (Aa) and would have the color determined by the dominant gene. In this case, all the offspring are black in color, which indicates that in the parents, the black hen is h0m0zygous dominant (AA), while the white hen is h0m0zygous recessive (aa).
In the cross that generated F2, we can see that within the offspring, the individuals in greater proportion are those who present heterozygosity and therefore have the "Aa" alleles. When incomplete dominance occurs, individuals in F2 who have heterozygosity have an intermediate phenotype between the two h0m0zygous phenotypes. As we can see in the question, in F2, heterozygous union members do not have an intermediate phenotype, but the black placement phenotype, which indicates that this is not a case of incomplete dominance.
This is also not a case of epistasis. This is because epistasis causes a gene to eliminate the expression of another gene, whether on the same chromosome or not. The result of this type of inheritance would be that some chickens had colored coloring, while others had no color at all in F2. As we can see, all chickens have colored coloring.
This indicates that neither student is correct.

Answers
In order to control analogous processes in human reproduction, genes and substances must be present in each cell from stages 1 to 7.
Giving birth to children who are similar to their parents is the process of reproduction. As we all know, human reproduction is a sexual process that requires internal fertilization during sexual activity.
Gametes are an organism’s reproductive cells. They are additionally known as sex cells. Sperm refers to male gametes, whilst ova or egg cells refer to female gametes.
The scrotum, testicles, epididymis, vas deferens, prostate, and seminal vesicles are all parts of the male reproductive system. The uterus, fallopian tubes, cervix, and ovary are the main components of a woman's internal reproductive system.

The energy molecule ___ is not stored in large quantities in cells because its high-energy phosphate bonds are too unstable.A) ATPB) ADP
Answers
The energy molecule ATP is not stored in large quantities in cells because its high-energy phosphate bonds are too unstable.
ATP stands for Adenosine Triphosphate. The energy of the ATP is stored in its anhydride bonds between the phosphate groups. The breaking of one molecule of ATP releases almost 7.3 kcal/mole of energy. This is why it is the primary source of energy inside the living organisms.
Phosphate bonds are the bonds between the phosphate groups of the ATP which are actually the phospho-anhydride bonds. There are two phospho-anhydride bonds in one molecule of ATP. The first is between the 2nd and 3rd phosphate groups and similarly the other is between the 1st and 2nd phosphate groups.
