Answer:

Answer

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:

There are millions of physical conditions but that's the only ones I could think of.

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.

Answer:

A. AIga

Explanation:

Alga can live in freshwater lakes or in salt water oceans. Most green alga occur in fresh water, usually attached to rocks and wood.

The ferns are most commonly plants of shaded damp forests of both temperate and tropical zones. Some fern species grow equally well on soil and upon rocks others are confined strictly to rocky habitats.

Mosses are distributed throughout the world except in salt water and are commonly found in moist shady locations. They are best known for those species that carpet woodland and forest floors. Hence, mosses break down exposed substrata, releasing nutrients for the use of more complex plants that succeed them.

Roses typically grow in warm climates and flower in the summer months. However, some roses can grow in the hot tropical climate found in Florida, while others can grow in hardiness zones as low as 2, which have winter temperatures that drop as low as -50 degrees Fahrenheit.

Hence, A. Alga is the correct Answer.

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:

All living things are composed of cells.

Cells are the basic units of structure and function for living things.

All cells come from pre-existing cells. Also, organisms grow by “adding on more cells” NOT by increasing the size of their cells.

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.

Answer: Income

Explanation:

In the ecosystem energy budget, primary productivity is like income. This is because primary production is the way in which energy enters an ecosystem.

I hope this helps :}

In the ecosystem energy budget, primary productivity is like income. Therefore, the correct option is B.

Primary productivity is the rate at which organic matter is produced by photosynthesis in an ecosystem. It represents the energy that enters the ecosystem from the sun and is available for consumption by other organisms. Therefore, like income, primary productivity is a source of energy that is available to be “spent” by organisms in the ecosystem.

Option A, debt, is not an appropriate analogy for primary productivity, as it implies a negative balance. Option C, the interest rate, is also not an appropriate analogy, as it does not represent a source of energy but rather a factor that affects the rate of exchange of energy. Option D, spending, is a closer analogy, but it does not capture the fact that primary productivity is a source of energy, rather than an action that depletes energy. Therefore, the correct option is B.

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.

Explanation:

Caladiums are tropical to sub-tropical plants grown mainly for their exquisite, colorful leaves. These foliage plants occasionally have a surprise up their metaphorical sleeve. Blooming on caladium plants isn’t common, but tubers planted in favorable locations tend to produce small flowers. These inflorescences aren’t as impactful as a rose or dahlia but have their own charm and, sometimes, a strong pleasant scent. There are several schools of thought on what to do with caladium flowers. While some growers believe pinching them off helps force energy to the tubers, others leave the small blooms with no ill effect on the plant.
