Answer:
Cell
Explanation:
Glial cells and neurons are the two types of cells that make up the nervous system. Four tasks are carried out by glial cells, which make up the nervous system's supporting framework: Give the neurons structural support. protect the neurons. A neuron is a specialized, impulse-conducting cell that is the functional unit of the nervous system, consisting of the cell body and its processes, the axon and dendrites. Three components make up neurons (nerve cells), which perform the integration and communication processes. Axon terminals, dendrites, and axons. The cell body, also known as the soma, is their fourth component and is responsible for the fundamental functions of neurons. In the illustration to the right, a "typical" neuron is depicted. The neuron, a specialized cell created to send information to other nerve cells, muscle cells, or gland cells, is the basic functional unit of the brain. Neurons are nervous system cells that communicate information to other nerve, muscle, and gland cells. Axons, dendrites, and a cell body make up the majority of neurons.

Environmental factors can influence natural selection because they can increase or decrease and what can they increase or decrease in
Environmental factors can influence natural selection because they can increase or decrease and what can they increase or decrease in the amount of genetic variation in a population.
What is natural selection?Populations of living things adapt and change through a process called natural selection. A population's members are naturally varied, which means that they are all distinctive in some ways. Because of this variety, some people have characteristics that suit their surroundings more than others.
Four requirements must be met for natural selection to take place: reproduction, inheritance, variety in physical traits, and variation in the number of children produced by each person.
Reproduction:
A population must procreate to produce a new generation in order for natural selection to affect it. Over many generations, people who have the characteristics that are most compatible with their environment tend to breed more than people who don't.
Heredity:
Since the genes of the parents combine to form the DNA of their offspring, heredity and reproduction go hand in hand. Natural selection must operate if parents with favourable qualities pass those traits on to their kids.
Variation in Characteristics:
Only when individuals within a community differ in their personal features can natural selection take place. For instance, different people must have varied colors in order to research natural selection on color within a population. There wouldn't be any traits for nature to "select" over others in the absence of variety in traits.
Fitness Variation:
Compared to its popular notion, fitness has a more technical meaning. Fitness in the context of evolution refers to an organism's capacity for maximum survival and reproduction. Natural selection cannot take place in a population unless its individuals have varying levels of fitness. Some people must have characteristics that make it easier for them to survive and procreate more frequently than others. Otherwise, natural selection cannot act to increase the number of people with advantageous features and decrease the number of people with undesirable qualities.

Hemophilia is an X-linked recessive disorder that is passed through generations and can be traced by using a pedigree.In the pedigree that is shown, which represents Irene's allele combination?
Answer:
XHXH
Explanation:
Hemophilia is an inherited genetic disorder that affects the body's ability to manufacture blood clots, which is a necessary step to prevent bleeding. Hemophilia A and B are both X-linked recessive illnesses, although females are not affected. X-linked recessive inheritance is a kind of inheritance in which a mutation in an X-chromosome gene causes the phenotype to be manifested in males who are hemizygous for the gene mutation because they have one X and one Y chromosome.

Option C, a pan heated to 100°C
Explanation:
The pan on the burner will be in direct contact of the heat released by burner and hence the pan will receive the direct flow of heat from the burner.
However, the water is the pan will be heated by the heat transferred from the pan to the water in it. Water will not receive heat directly from the burner.
Hence, option C is correct
Use the model here to describe the transfer of matter and flow of energy from one trophic level to another within an ecosystem. All of the following must be addressed in your response to receive full credit:
a. Discuss the transfer of biomass when one organism eats another. Use your knowledge of digestion to discuss how food is broken down and used by the consumer.
b. Explain what happens to the energy that is not transferred from one organism to another.
c. Explain why there are typically fewer organisms at the top of an energy pyramid.
d. Use specific numbers and calculations to support your explanation.
The food chain and food web are used to transfer energy. Plants, who are the primary energy providers in the ecosystem, use their chloroplasts to collect sunlight, which is then partially converted into chemical energy during photosynthesis.
a)
When herbivores eat (are the primary consumers of) plants as food, this energy is transferred to the primary consumers in the food chain. This energy is stored in various organic products in plants. Then, the chemical energy contained in plant products is converted into kinetic energy, degrading the energy by turning it into heat. The secondary consumers come next. Further deterioration will occur when these herbivores are consumed by secondary consumers. Finally, energy will once more be destroyed when tertiary consumers eat the carnivores. As a result, the energy flow is only in one direction i.e., unidirectional.b)
Additionally, the energy flow in a food chain adheres to the 10% law.This law states that only 10% of energy is transferred from one trophic level to the next, with the remaining 90% being lost during the digestion process of the organism itself.c)
There are typically fewer organisms at the top of an energy pyramid because It has the least quantity of energy, the top level of an energy pyramid has the fewest organisms. Most ecosystems only have four trophic levels because there is eventually insufficient energy to maintain further trophic levels.d)
For instance, let us assume that a plant at the producer level produces 1000 Kcal of energy.When a primary producer eats this plant, it will only get 10% of the energy produced by the plant i.e., 1000/10 = 100 Kcal. the rest 90% will be used up by the plant itself for its metabolism.Further when a secondary consumer eats the primary consumer, it will only get 10% of the energy produced by the plant i.e., 100/10 = 10 Kcal.Lastly, as the tertiary consumer eats the secondary consumer, it will only get 10/10 = 1kcal.learn more about ecosystem here: https://brainly.com/question/842527

Polaris disappears into the horizon as seen from the equator, and is not visible from the south of the equator. Finding Polaris in the Northern Hemisphere indicates that you are aware of the direction north.
What is the importance of Polaris?Directly above Earth's North Pole is the Pole Star, or Polaris. Due to its location over the North Pole, the pole star is aligned with the earth's axis. As the sole star that is stationary, it is crucial for orientation.
It makes a fairly small circle over the course of a day since it is so close to the celestial equator. As a result, Polaris is a trustworthy indicator of north, since it always remains in nearly the same location in the sky.

What engineer Nikolaus August Otto developed?Engineer Nikolaus August Otto developed the first four-stroke internal combustion engine and established the Otto cycle, a well-known theoretical cycle that governs the operation of explosive engines.
Otto's engine outperformed the steam engine in use at the time in a number of ways. One of them is their light weight, as steam engines need large water reservoirs and fuel to burn in order to heat the water, which in this case would be charcoal or firewood. In addition to being light, the internal combustion engine consumed little fuel, even benzene. Another factor was Otto cycle internal combustion engines' power, which also outperformed steam engines in terms of size ratio.
These benefits put pressure on the automotive sector to build vehicles with this kind of technology. Blacksmiths were compelled to learn new skills in order to use this new technology.
