Which organisms are prokaryotes?
archaea
fungi
protists
plants
Archaea are prokaryotes.
What are prokaryotes?The simplest form of life on our planet is made up of single celled organisms called prokaryotes that lack any nucleus or membrane bound organelles. Despite their basic structure compared to eukaryotic cells they have extreme significance for our environment as they constitute the majority of life forms on Earth.
Prokaryotes can be broadly divided into two groups: bacteria and archaea. Bacteria outnumbers all other types present globally and flourish across all possible conditions - both regular and adverse including tough terrains like hot springs or acidic lakes; however archaic forms can survive even some brutal conditions such as deep sea zones or within rocks.

Why is knowing agricultural statistics, background information, and soil characteristics about the territory in which your farm is located important?
Knowing the agricultural statistics of where your farm is located is important because it can help a farmer to identify the efficiencies that will lead to more productivity and profitability, less input costs, and optimized fertilizer use. The background information is important to farmers because it helps a farmer know whether or not the ground is good for growing crops, if something had happened to the land before their use. Soil characteristics are important to farmers because fertile soil is important for crop growth. The soil needs to be able to allow water and air to infiltrate, roots to be able to move more, and for biota to be able to thrive.

Answer:
Altruism occurs when an individual gives to another out of concern or thought of one's well-being. If an individual has no expectation of returning to a restaurant then leaving a generous tip is considered altruistic because there is no expectation of a reward from the server. If the customer does not return, the server is unable to exchange the gift or tip for good service. Therefore, the customer who tips is giving out of care or concern for the well-being of the server rather than giving with the intention of receiving an external reward.
How do bacterial species build antibiotic resistance?
Explanation:
So when u take antibiotics you kill lots of the bacteria. however you don't kill all of them. the bacteria that is left over hasn't been killed because they are resistant to the antibiotics taken. if left these bacteria will reproduce and build and species resistant to that type of antibiotics which can be incredibly dangerous. this is why it is necessary to finish your full antibiotics course so even if u feel better just to make sure you kill all the bacteria.
why osmosis is special case of diffusion?
Answer:
Diffusion can be called as osmosis in some cases because if the substance is liquid and passes through a semi-permiable membrane then its osmosis.
WELCOME!
Answer:
Osmosis is a special kind of diffusion because in both cases there is a movement of particles from a higher concentration region to a lower concentration region. The only difference is that osmosis is applicable to the movement of the solvent only through the semi-permeable membrane where the solvent is water.

17) Determine the expected phenotypic ratio of offspring from a cross between a striped watermelon
with thick skin and a light green watermelon with thick skin
• Striped watermelons result from a cross between a light green watermelon and a dark green
watermelon
●
Thick skins are dominant to thin-skins
[5]
Parents:
The expected phenotypic ratio of offspring from a cross between a striped watermelon with thick skin is 1/2 thick skin and 1/2 striped watermelon.
What is dominance?In genetics, dominance refers to the expression of a given allele or gene variant in heterozygous individuals.
In dominance, this dominant allele masks the expression of the recessive allele for a given gene locus.
In conclusion, the expected phenotypic ratio of offspring from a cross between a striped watermelon with thick skin is 1/2 thick skin and 1/2 striped watermelon.

Planet A has a tilt a of five degrees. What seasonal changes would be expected on this planet?
Extreme temperature changes between seasons
Little to no change in temperatures between seasons
Seasonal changes along the equator only
Seasonal changes at the poles only
Answer:
B. Little to no change in temperatures between seasons.
Assuming planet A is the earth, the earth is very slightly rotated on its axis toward the sun and Jupiter, so there would not be a dramatic change if we tilted the earth 5 degrees.

The illustration shows an ocean food chain and the concentrations of the toxin DDT at each trophic level. What conclusions can be made as to how DDT impacts this food chain? Include where the concentration of DDT is likely to be lowest, and where it is likely to be highest
DDT increases as it moves up a food chain.
Explain how?DDT increases or biomagnifies if we look at a food chain. DDT is fat-soluble, which means animals store it in fatty tissues. It also takes a relatively long amount of time to break down.
Thus, if a predator consumes multiple organisms and each organism has a small amount of DDT, the amount of DDT in the predator is going to be the result of all of those small amounts combined.

n this experiment, you need to examine the idea of thermal energy transfer. Using a controlled experiment, what might a good question about the variables that affect thermal energy transfer be? Thermal energy transfer depends on many properties, but limit your question to only two.
The thermal conductivity and temperature difference between the surrounding plays a crucial role in the transfer of thermal energy between the materials.
What are the three modes of thermal energy transfer?The three modes of thermal energy transfer include conduction (direct contact of atoms), convection (migration of warm particles), and radiation (migration of electromagnetic waves).
The first property is thermal conductivity. Examples include a cube of ice when positioned in the hand of a man. It causes the ice to melt via the thermal conduction from men's hands.
The second property is the temperature difference. Examples include when a hot cup of tea mingled with a cold glass of water. It changes the temperature to a new value which is different from the exact temperature of both initial fluids.
Therefore, it is well described above.

Why do large-scale convection currents occur in the atmosphere?
Explanation:
Convection drives the circulation of air in the earth's atmosphere. The sun heats the air near the earth's equator, which becomes less dense and rises upward. As it rises, it cools and becomes less dense than the air around it, spreading out and descending toward the equator again.
