What does the difference in distribution tell you about the cells in the treated sample?.
The difference in distribution tell you about the cells in the treated sample, is that the treated cancer cells are arrested at the G1 phase.
They give the body structure, absorb nutrients from meals, turn those nutrients into energy, and perform certain tasks. Additionally, cells have the ability to replicate themselves and contain the body's genetic material. Each component of a cell has a different purpose.
There are two different types of cells: prokaryotic cells, which lack a nucleus but still have a nucleoid area, and eukaryotic cells, which have a nucleus. Eukaryotes can either be single-celled or multicellular, in contrast to prokaryotes, which are single-celled organisms.
The parasitic bacteria Mycoplasma gallicepticum, which inhabits the respiratory, genital, and urinary systems of primates, is thought to be the tiniest known creature capable of autonomous development and reproduction.

. An experiment is designed to determine the viscosity of honey flow at different temperatures. What is the control group for the experiment?
honey at 75˚C .honey at 20˚c .honey at 50˚C .honey at room temperature
The control group for the experiment is honey at 20˚c.
The distance traveled by the honey is the independent variable and the temperature is the dependent variable. The distance the honey travels is the independent variable and the temperature is the control. Viscosity values decreased with increasing temperature. The temperature-induced effects in the investigated range were more significant in the low-temperature range whereas the viscosity did not change much at high temperatures.
The dependent variable is the viscosity of the liquid. This is determined by measuring flow using a measuring cup and a stopwatch. The viscosity of honey depends on the amount of water and the type and amount of sugar it contains. The higher the water concentration, the lower the viscosity of honey. Temperature also changes the viscosity of honey, and heat is often used to make honey easier to process.

Do stomata in plants evaporate water?The plant's stomata—tiny, closeable pores like structures on the surfaces of leaves—ultimately release the water to the atmosphere as vapour. Transpiration refers to the process of water absorption at the roots, water movement through plant tissues, and vapour emission via leaves.
Nearly all terrestrial plants employ the same pores, known as stomata, to absorb carbon dioxide and release oxygen, demonstrating how important this evolutionary invention is to plants' identity.

The digestive processes are ingestion, propulsion, mechanical digestion, chemical digestion, absorption, and defecation.
What is digestion?Digestion is a complex process that transforms the food you eat into nutrients that your body uses for energy, growth, and cell repair that it needs to survive. Fermentation processes also involve the production of waste products that must be disposed of.A digestive system breaks down food into nutrients such as carbohydrates, fats and proteins. They are then absorbed into the bloodstream and can be used by the body for energy, growth, and repair. Unused material is discarded as a surface. During digestion, muscles push food from the top of the stomach to the bottom.

Using the theories of the cells, we got that the movement of substances across the cell membrane that does require the use of energy by the cell is active transport.
The contents of the cell are completely surrounded by its cell membrane or plasma membrane. Thus, any communication between cell and the extracellular medium is mediated by cell membranes. These cell membranes serves two important functions:
It must retain the dissolved materials of cell so that they do not simply leaks out into the environment.It should also allow the necessary exchange of the materials into and out of the cell.There are two major methods for moving molecules across the membrane, and it is related to whether or not the cell energy is used. Passive mechanisms, such as the diffusion, require no energy to function, whereas active transport does. In passive transport, an ion or the molecule crosses a membrane and moves down its concentration or electrochemical gradient.

Flies are scavengers and tend to break down dead organisms. Based on this information, what is a plant characteristic that would best attract flies?.
Scavengers are organisms that feed on dead organisms. The majority of the scavengers are drawn to the flowers that emit a rotten odor.
What are Scavengers?
A scavenger is an organism that feeds primarily on decaying biomass, such as meat or rotting plant material. Many scavengers are carnivores, which are organisms that eat meat.
Scavengers are a component of the food web, which describes which organisms eat which other organisms in nature. The food web divides organisms into trophic, or nutritional, levels.
There are three types of trophic levels. The first trophic level is autotrophs, or organisms that produce their own food. Plants and algae are examples of this. The second trophic level is herbivores, or organisms that consume plants and other autotrophs. The third trophic level includes scavengers, other carnivores, and omnivores, which consume both plants and animals.
Scavengers play a critical role in the food web. They keep the bodies of dead animals, or carrion, out of the ecosystem. Scavengers break down this organic material and recycle it as nutrients back into the ecosystem.
Scavengers are some birds. Vultures only consume the carcasses of dead animals.

For mammals living in cold habitats, would smaller or larger species require relatively thicker fur?.
For mammals living in cold habitats, smaller species might require relatively thicker fur.
As they get closer to the poles, the majority of vertebrate animals gain weight. Numerous animal species benefit from being larger in the colder climates found at high latitudes and elevations. Bergmann's Rule, a phenomenon, explains how heavier animals have a smaller surface area to volume ratio, which aids in reducing heat loss.
Many (non-polar) animals are ectotherms, meaning that their internal heat production is so low that they rely on their surroundings to warm them up to a temperature where their body and enzymes can function well enough for an active and functional life. Smaller animals struggle in cold climates because they have a greater relative surface area to lose heat.
