Answer:

c. Individuals experience differential success in their ability to survive or reproduce due to differences in certain traits.

Explanation:

Natural selection works on a population when genetic variations are present in its members. Some genetic traits make the organisms better adapted to the prevailing surroundings. These individuals survive more and reproduce more successfully due to the presence of specific genetic traits. Over the generations, the proportion of the beneficial genetic trait increases due to the increased reproductive success of these individuals. This is called natural selection. On the other hand, the individuals that lack these traits survive and reproduce less.

Many foods must be refrigerated to prevent spoiling (microbial growth). Explain why honey (which is ∼82% carbohydrate by weight)
VLD [36.1K]

Answer;

-Honey contains a considerable amount of sugar (about 82% carbohydrate) and therefore when a microbe (e.g., a fungal spore or bacterium) lands on honey the process of osmosis causes water to be drawn out of the microbe thus blocking its ability to live and proliferate.

Explanation;

Antibiotics are used to kill or inhibit bacteria growth. Honey contains hydrogen peroxide, which may account for some of its antibacterial properties. It also has a high sugar content, which can help stop the growth of certain bacteria.

-Additionally, honey has a low pH level. This works to pull moisture away from bacteria, causing the bacteria to get dehydrated and die off.

Check all of the statements that are true regarding keratinized stratified squamous epithelium.
strojnjashka [21]

Answer;

-Keratinized stratified squamous epithelium forms the epidermis of the skin.

-In keratinized stratified squamous epithelial tissue, the cells on the apical (outer) surface are dead.

Explanation;

-Stratified squamous epithelium is a type of tissue found covering and lining parts of the body. Stratified squamous epithelium may be keratinized or nonkeratinized. Non-keratinized surfaces must be kept moist by bodily secretions to prevent them from drying out.

-The cells on the surface of stratified squamous keratinized epithelium are very flat. Not only are they flat, but they are no longer alive. They have no nucleus or organelles. They are filled with a protein called keratin, which is what makes our skin waterproof.

Bill does 1500 J of work on a lever, which is a simple machine. The lever does 1350 J of work on a stone.
Oksanka [162]
Efficiency is the measure of how much work or energy is conserved in a process. In many processes, work or energy is lost, for example as waste heat or vibration. The efficiency is the energy output, divided by the energy input, and expressed as a percentage.
Efficiency is the energy output, divided by the energy input, and expressed as a percentage. 
Efficiency = (1350/1500)×100
                = 90%

Considering that a hydrophilic stain was used to stain the skin, explain why the fat vacuoles in adipocytes are white (Hint: Rem
vazorg [7]

Answer:

The hydrophilic nature of the stain explains that these molecules are polar and charge molecules. therefore, attracts the water molecule but due to their polar nature, it will avoid lipid or fat molecules.

Adipocytes are the cells that are made up of fat or lipids that are hydrophobic due to their non-polar nature and due to this fact, these hydrophilic stains will not be able to stain adipocytes and will not be colored by the stain.
