Genetic Changes in humans over past thousands of years is called Evolution, It is change that occurs in an organism in course of time. Evolution is caused due to Variation that an organism acquires as response to adapt to its environment.

Evolution is the process by which an organism changes in course of time as response to its struggles they experience and these changes are called Genetic Variation. Organisms that acquire favourable variations will overcome the struggle for existence and become the fittest. The fittest individuals are selected by a process called Natural Selection.

Displays the three forms of evolution: divergent, convergent, and parallel.

Answer:

When a child is formed, they get half of their genes or traits from each parent. These genes are like tiny sets of instructions that determine things like a child's hair color, eye color, and height. Each parent contributes their genes through their sperm or egg. For example, if a parent has brown eyes, they will contribute a gene for brown eyes to their child. If the other parent has blue eyes, they will contribute a gene for blue eyes to the child.

However, not every trait from each parent will appear in the child. Some traits are dominant, which means they will show up even if only one parent contributes that gene. Other traits are recessive, which means they will only show up if both parents contribute that gene. And sometimes, traits can be a combination of both parents' genes.

In terms of human reproduction, we are the result of sexual reproduction. This means that an egg from a female and a sperm from a male combine to form a zygote, which eventually develops into a fetus and then a baby. Each parent contributes half of their genetic material to the child, resulting in a unique combination of traits.

Explanation:

Sana makatulong

A child inherits traits from both parents through a process known as genetic inheritance. Humans have two sets of chromosomes, one set inherited from the mother and one from the father. Each set contains genes that determine various traits such as physical characteristics, eye color, hair type, and many others.

Each parent contributes their traits to the child through the genes on their respective chromosomes. Traits are typically determined by the combination of alleles. For example, if the mother has a gene for brown eyes and the father has a gene for blue eyes, the child may inherit one allele for brown eyes and one allele for blue eyes.

During reproduction, the parents' genetic material combines through the process of fertilization. The father's sperm carries genetic information in the form of chromosomes, while the mother's egg also contains chromosomes. When the sperm fertilizes the egg, their genetic material combines to form a unique set of chromosomes in the resulting zygote.

Answer:

The correct answer is: wildflowers, rabbits, foxes

Explanation:

The correct answer is: wildflowers, rabbits, foxes

In a food chain, energy is transferred from one organism to another in a linear sequence. The organisms at the beginning of the food chain are usually producers, such as plants, which are eaten by herbivores, such as rabbits. In turn, the herbivores are consumed by predators, such as foxes.

In a temperate deciduous forest, wildflowers are a common type of plant that can be eaten by rabbits, which are in turn eaten by foxes. Therefore, the correct food chain is wildflowers (producer) → rabbits (herbivore) → foxes (predator).

The organisms that feed on dead and decaying matter are called Saprotrophs.

An organism that feeds on dead and decaying organic matter is called a saprotroph. These organisms are heterotrophic, which means that they obtain their food from other sources. They are important in the ecosystem because they break down dead organic matter and recycle it back into the soil, making nutrients available to other living organisms

Answer:

A. Saprotrophs

Explanation:

Saprotrophs are organisms that obtain their nutrients by feeding on dead and decaying matter. They play a crucial role in the ecosystem by decomposing organic material and recycling nutrients back into the environment.

These organisms secrete enzymes that break down complex organic compounds into simpler substances, such as sugars and amino acids, which they can absorb and utilize for their own growth and energy needs. Examples of saprotrophs include fungi (such as mushrooms and molds) and certain bacteria.

Unlike autotrophs, which can produce their own food through photosynthesis or chemosynthesis, saprotrophs rely on external sources of organic matter for their nutrition. They actively decompose dead plants, animals, and other organic materials, aiding in the process of nutrient recycling and decomposition.

Heterotrophs, on the other hand, are a broader category of organisms that obtain their nutrients by consuming other living or dead organisms. This includes saprotrophs, as well as other types of organisms such as herbivores, carnivores, and omnivores.

Parasites, meanwhile, are organisms that live in or on other organisms, known as hosts, and obtain their nutrients from the host while causing harm or damage to it. Unlike saprotrophs, parasites typically rely on a living host for their sustenance rather than feeding on dead and decaying matter.

Answer:

A. The level of sucrose solution will rise in the glass tube because water molecules will pass through the semipermeable membrane into the tube as water potential is higher outside than inside the tube.

B. The apparatus can be modified to measure the rate of osmosis at different temperatures by doing the following :

1. Using a waterbath in order to heat the water and a thermometer to measure different temperatures.

2. Using a scale such as a ruler attached to the glass tube to measure the increase in height at different temperatures.

3. Using a stopwatch to record time taken for unit increase in the height of waterat different temperatures.

Explanation:

A. Osmosis is the movement of water molecules from a region of low solute concentration or high water potential to a region of high solute concentration or low water potential through a semipermeable membrane until equilibrium concentration is attained.

The movement of water molecules is based on a concentration gradient, from a region where there are more water molecules to a region where there are fewer water molecules.

The sucrose solution has a higher solute concentation but lower water potential due to fewer water molecules compared to water in the beaker, therefore, water molecules will pass through the semipermeable membrane into the glass tube resulting in an increase in the level of sucrose solution in the glass tube.

B. The apparatus can be modified to measure the rate of osmosis at different temperatures by doing the following :

1. Using a waterbath in order to heat the water and a thermometer to measure different temperatures.

2. Using a scale such as a ruler attached to the glass tube to measure the increase in height at different temperatures.

Conditional Response: The itch that Meron experiences when she sees a commercial for the hotel is the conditional response.

Conditional Stimulus: The commercial for the hotel serves as the conditional stimulus.

Unconditional Response: The itch that Meron experiences after being bitten by bedbugs is the unconditional response.

Unconditional Stimulus: The bedbug bites that caused Meron to develop an itch serve as the unconditional stimulus.

In this scenario, the conditional response, conditional stimulus, unconditional response, and unconditional stimulus can be identified according to Pavlov's classical conditioning.

Conditional Response: The itch that Meron experiences when she sees a commercial for the hotel is the conditional response. It is a learned response that is triggered by a specific stimulus.

Conditional Stimulus: The commercial for the hotel serves as the conditional stimulus. It is the previously neutral stimulus that, through association with the unconditional stimulus, elicits the conditional response. In this case, the conditional stimulus is the visual or auditory cues associated with the hotel commercial.

Unconditional Response: The itch that Meron experiences after being bitten by bedbugs is the unconditional response. It is an unlearned, natural response that is automatically elicited by the unconditional stimulus.

Unconditional Stimulus: The bedbug bites that caused Meron to develop an itch serve as the unconditional stimulus. It is the stimulus that naturally and automatically triggers the unconditional response, which is the itch.

Through classical conditioning, the conditional stimulus (hotel commercial) becomes associated with the unconditional stimulus (bedbug bites), leading to the development of the conditional response (itch) whenever Meron encounters the conditional stimulus.
