Your bronchioles are some of the smallest airways in your lungs. Inhaled air passes through tiny ducts from the bronchioles into elastic air sacs (alveoli). The alveoli are surrounded by the alveolar-capillary membrane, which normally prevents liquid in the capillaries from entering the air sacs.

Answer:

If there's a blockage of this channel, like when you have a stuffy nose due to the flu or a cold, odors can't get to the sensory cells the smells stimulate. This results in you losing a lot of your ability to taste the flavor of food. In this manner, your senses of taste and smell work closely together.

Answer:

It will affect your smell because you can have a lot of snot in your nose and your nose will be stopped up with all that stuff.

Answer:

Carbohydrates, such as sugar and starch, for example, are readily broken down into glucose, the body's principal energy source. Glucose can be used immediately as fuel, or can be sent to the liver and muscles and stored as glycogen.

Photosynthetic protists such as the various types of algae contain plastids. These organelles serve as the site of photosynthesis (the process of harvesting sunlight to produce nutrients in the form of carbohydrates). The plastids of some protists are similar to those of plants.

Answer:

Sister chromatids / centromeres: When a single chromosome has been replicated in copies, each copy is called a sister chromatids.

A special part of the chromosome called the centromere holds the two sister chromatids together. A centromere is like a built-in rubber band for two sister chromosomes.

Mother cell / daughter cell: identical.

Daughter cells are genetically identical to the mother cell at the stage of production through mitosis.

On the other hand, at the stage of production through meiosis, the daughter cells are genetically different and contain only half of the genetic material of the mother cell.

Interphase / cell division: A cell spends most of its time in what is called interphase, and during this time it grows,

replicates its chromosomes, and prepare for cell division.

The cell then leaves Interphase, undergoes mitosis, and completes its division.

DNA / chromosome: Genes are segments of deoxyirbonucleic acid (DNA) that contain the code for specific protein that functions in one or more types of cell in the body

Chromosomes are structures within cells that contains a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.

Mitosis / cytokinesis: Basically, mitosis is a process by which the duplicated genome in a cell is separated into halves that are identical in nature.

Cytokinesis is the process where the cytoplasm of the cell divides to form two 'daughter' cells. The result is the formation of two 'daughter cells', each having a nucleus.

Bacteria lack a nucleus, mitochondria, chloroplasts and organelles. Protists can either be single-celled or multiple called. They contain a nucleus surrounded by a nuclear membrane. The DNA or genetic material of a bacteria is not surrounded by a protective membrane known as a nuclear membrane.

Answer:

Vacuoles in animal cells do NOT help the cell take its shape, however, in plant cells, vacuoles are larger, and DO affect the shape of the cell.

The function of the vacuole in plants is different from that in animals, as the vacuole in animals is smaller, while in plants it is larger and pushes the nucleus to one side while consisting of water and other materials.

Vacuoles are cell organelles found in both plants and animals, in plants, vacuoles are large, fluid-filled structures that occupy a large portion of the cell, and they perform several important functions, including storing water and helping to maintain the shape of the cell, while in animals, vacuoles are smaller and less in number than in plants, as they have a variety of functions, like storing waste materials, etc.

Hence, the function of the vacuole in plants is different from that in animals, as the vacuole in animals is smaller, while in plants it is larger and pushes the nucleus to one side while consisting of water and other materials

Answer:

It is the iris that determines eye color.

Explanation:

A person's eye color results from pigmentation of a structure called the iris, which surrounds the black hole in the center of the eye, the pupil. It helps control how much light can enter the eye. The color of the iris can obviously range from blue, green, brown and I think grey too if fiction books can be trusted lol

Answer:

A mutation could have no effect on the organism that inherits the mutation because of the chances of the organism's parents/producers. One parent may be dominantly having the mutation while the other parent may have the mutation but does not display its effects, thus labeling this parent as a carrier of the trait/mutation. Drawing a punnet square would best be used to describe the possibilities of each offspring and how each carries or shows the mutation inherited from their parents.

https://brainly.com/question/14165885

a) In a food chain, arrows show the movement of nutrients or energy from one organism to another. It refers to the direction of transfer of energy or nutrients from the organism being consumed to the organism consuming it.

b) The producer in the diagrammatic food chain is lettuce, followed by green fly, ladybug, thrush and cat. Producers—also called autotrophs—are living things that can make their own food through photosynthesis or chemosynthesis, the process by which sunlight or inorganic substances are converted into energy-rich organic molecules.

c. Ladybird is the third trophic level of the food chain. The term "trophic level" describes the place an organism occupies in a food chain or web, from where it obtains its food and energy. In this scenario the greenfly is the primary consumer at the second trophic level, while the ladybird is the secondary consumer at the third trophic level. Lettuce is the first trophic level in this scenario (producer).

d.Cat is the third largest consumer in the provided food chain. In a food chain or web, tertiary consumers are those species at the highest trophic level. Typically, they are carnivores that prey on other carnivores or secondary consumers.

e) Sun is the primary energy source that powers the food chain. Most ecosystems get their energy mostly from the sun. As the species consumes and is consumed by other organisms, it is passed along the food chain after being captured by producers (such as plants) through photosynthesis.

The two-word term used to describe the annual shopping and sports is Black Friday.

From the United States (U.S.) financial history, the two-term word black Friday was first used in 1869.

The first annual black Friday occured in Philadelphia in which alot of retailers attracted their key customers and made profits through the discount they placed on their products.

Black Friday was used to describe the financial crisis after the United States's gold market crashed.

Literally, black should depict something negative or loss but on the contrary, the business world uses black to describe profit.

Therefore, the two-word term used to describe the annual shopping and sports is Black Friday.

Answer: The NEGATIVE CONTROL is the

test tube that is filled with ONLY distilled

water.

Explanation:

A negative control of an experiment is

carried out alongside the main primary

experiment except that the treatment is

changed to something that is predicted

to have no result. In the negative

control, the student does not expect any

response. This would help the student

compare the result of a new experiment

against an already known existing results.

Analysing the experiment carried out

by the student, She filled two test tubes

with distilled water and placed a piece

of Elodea in one of the tubes, leaving

the other without a plant. The other test

tube that contains only distilled water is

the negative control because she wasn't

expecting any result from it. It's also

served as a control sample to the primary

experiment. This is observed as she

blew in each tube to add carbon dioxide,

which caused the distilled water to

become more acidic. This would help the

student know that the that experimental

results are valid and to ensure that time is

saved

Explanation:

Heterotrophs are consumers, cannot make their own foods, and have some of them have the capacity to consume autotrophs. Hence, they are not at the base of most food webs.

Heterotrophs are organisms that have no capacity to manufacture their own foods, unlike autotrophs.

They depend on other organisms for their foods. Hence, they are known as consumers, unlike autotrophs that are called producers.

Heterotrophs are of different types:

Thus, heterotrophs do not occupy the base of food webs. The base of food webs are mostly occupied by autotrophs, the producers.

Fungus

Explanation:

Chitin is a fibrous substance consisting of polysaccharides and forming the major constituent in the exoskeleton of arthropods and the cell walls of fungi. This would point to it most likely being a fungal agent. Hope this helps!

Chitin is a natural polymer and a nitrogenous carbohydrate. The cell walls of fungus pathogens are formed of the N-acetylglucosamine polymer chitin.

Pathogens are germs that enter, grow, and cause sickness in their host's body. It simply needs a host body to live.

Pathogens have the ability to circumvent the immune system. It likewise relies on body chemicals to survive. Depending on the kind, these bacteria can move from one host to another in a variety of ways.

The plant is home to millions of fungus species. Not all of them are pathogenic. Only roughly 300 of them are capable of causing disease. Fungi can be found on the surface of your skin or inside your food. They only cause illness if they overgrow.

Fungi have two protective layers, a membrane, and a cell wall, and they are difficult to destroy. The severity of a fungal infection might vary.

Thus, we can conclude that the unknown pathogenic organism is fungus because fungus pathogens contain chitin.
