Answer:
This type of natural selection occurs when there are selective pressures working against two extremes of a trait and therefore the intermediate or “middle” trait is selected for. If we look at a distribution of traits in the population, it is noticeable that a standard distribution is followed: Example: For a plant, the plants that are very tall are exposed to more wind and are at risk of being blown over. The plants that are very short fail to get enough sunlight to prosper. Therefore, the plants that are a middle height between the two get both enough sunlight and protection from the wind.
This type of natural selection occurs when selective pressures are working in favour of one extreme of a trait. Therefore when looking at a distribution of traits in a population, a graph tends to lean more to one side: Example: Giraffes with the longest necks are able to reach more leaves to each. Selective pressures will work in the advantage of the longer neck giraffes and therefore the distribution of the trait within the population will shift towards the longer neck trait.
This type of natural selection occurs when selective pressures are working in favour of the two extremes and against the intermediate trait. This type of selection is not as common. When looking at a trait distribution, there are two higher peaks on both ends with a minimum in the middle as such: Example: An area that has black, white and grey bunnies contains both black and white rocks. Both the traits for white and black will be favored by natural selection since they both prove useful for camouflage. The intermediate trait of grey does not prove as useful and therefore selective pressures act against the trait.
Genes help to define who an individual is inside and out. In addition to visible traits like weight and eye color, psychological qualities such as personality traits, intelligence, risk of mental illness, and more have been linked to genetics.
Explanation:
This is what I could find.
2: gene is a unit of heredity which is transferred from a parent to there kids(offspring). They relate to traits in people because if you’re born tall you got it from your mom/dad or their family traits.

What is the name of a double layer of phospholipids (called lipid bilayer)?
Answers
The name of a double layer of phospholipids is called a lipid bilayer.
The lipid bilayer is a fundamental component of cell membranes and plays a crucial role in maintaining the integrity and function of the cell. It consists of two layers of phospholipids arranged in such a way that the hydrophobic (water-repellent) fatty acid tails are sandwiched between the hydrophilic (water-loving) phosphate heads.
This arrangement creates a barrier that controls the passage of substances into and out of the cell, allowing for selective permeability. The lipid bilayer also houses various proteins, cholesterol molecules, and other components that contribute to the overall structure and function of the cell membrane.
Thus, the correct option is lipid bilayer.

Hydrogen bonds can be found between no other molecules except water.
Answers
Answer:
Without hydrogen bonds, water molecules would move faster more rapidly, with less input of heat energy, causing the temperature to increase more for each calorie of heat added.
Explanation: This would also greatly reduce the amount of heat energy needed for phase changes from ice to liquid, and from liquid to vapor.
Answer: Not really a question but....Two molecules of water can form a hydrogen bond between them that is to say oxygen-hydrogen bonding; the simplest case, when only two molecules are present, is called the water dimer and is often used as a model system.

Coral polyps secrete a rock-like skeleton of calcium carbonate around them. Calcium carbonate is also the dominant consituent of the rock, limestone. Because modern corals live in large colonies, these skeletons can become quite large, sometimes forming reefs.the soft tissue decays which leaves a hard skeleton behind the skeleton also that was preserved as a fossil of ancient coral and the coral that exists today all belong to the order of Scleractinia (SCLER-ac-TIN-ee-a). in the past the fossils found today lead to the conclusion that their where other kinds of coral which are now extinct The order Rugosa was dominated by solitary corals in which each coral polyp had its own skeleton. Rugose means wrinkled or rough, and the outer surfaces of most rugose coral skeletons has a wrinkled appearance. Because some of the solitary rugose corals formed horn-shaped skeletons, they are called horn corals. Some Rugose corals also formed colonies and coral heads. The order Tabulata consisted entirely of groups of coral animals that lived in large colonies with a shared skeleton. These colonial corals grew in mounds, branching shapes, as chain-like shapes, and even in shapes resembling pipe organs.

Carbohydrates have chemical bonds that are a good source of energy for living things. A monosaccharide is a carbohydrate made by plants when energy from the sun combines water and carbon dioxide.
How are the two other types of carbohydrates formed? Give examples of each type.
Answers
Explanation:
The other two types of carbohydrates, disaccharides and polysaccharides, are formed when monosaccharides link together to form larger molecules and chains. A disaccharide is a sugar that is made from two monosaccharides (di=two). For example, sucrose is a disaccharide that is made from the bonding of glucose with fructose, which are both monosaccharides. Sucrose is known as table sugar, and is found naturally in plants. Polysaccharides are large, complex molecules that are formed when monosaccharides or disaccharides link together in repeating units to form long chains. The most abundant polysaccharide in the world is cellulose, the substance that makes up the cell wall of plant cells. Starches are also examples of polysaccharides, and these are stored in plants such as grains, corn and wheat.
All living organisms must obtain energy in order to survive, and most organisms rely on carbohydrates as energy sources. These molecules are made through the process of photosynthesis, and they store the sun's energy within them.

C.500m, 0m
Answers
Answer:
Distance is 500 m and displacement is 0.
Explanation:
Distance traveled by an object is equal to the total path covered during the entire journey. Displacement of an object is the shortest path covered.
In this case, we need to find the distance and the displacement of the race car drivers in the Indy 500 m race in a circular path.
In a race, the object must reach the initial position after some time. It means that the final and the initial position is the same. As a result, the shortest path covered i.e. displacement of the car is equal to 0. On the other hand, total traveled distance is 500 m.

Large, circular lily pads are able to float on the water's surface.
Answers
Answer:
true
Explanation:
they're buoyancy
The property of water in "Large, circular lily pads are able to float on the water's surface" is cohesion.
What is cohesion?Cohesion refers to the attraction of one water to another. This force will cause the water in the lake to develop surface tension. The large and thin leaf of the water lily gives it a low force per area.
The leaf will float above the water if the force acting on the surface is not greater than surface tension. The ability of water spiders to walk on the surface tension of the water.
The leaves of lotus float on the water because the bottom of the leaves have edges and thick ribs that capture air between them, which helps them to float on the water.

In diffusion, the net movement of a substance travels down its concentration gradient
Explain using the image below.
Answers
Answer:
The diagram is a representation of the diffusion.
Explanation:
In this image, there are molecules or concentrations of a particular substance is represented by the purple circle on both sides of the box in left side concentration is higher than the right side.
So the movement of these molecules is from the left corner to the right down the concentration gradient, this type of movement of the substance is known as the diffusion which moves from high concentration to low concentration.
Diffusion is the movement of molecules from the higher concentration to lower concentration.
Diffusion is the movement of molecules from the area of higher concentration to the area of lower concentration. In the image, higher concentration of molecules are present on the left side whereas lower number of molecules are present on the right side of the image.
So here diffusion occurs by movement of molecules from higher concentration to lower concentration means from left to right side of the image until the concentration becomes equal so we can conclude diffusion is the movement of molecules from the higher concentration to lower concentration.
