3. Animals can develop illnesses from bacterial infections. Antibiotic medications are sometimes prescribed to treat these infections. What do you think might happen to a population of bacteria that is exposed frequently to such antibiotics?
Answer:
it could mutate to where the antibiotic no longer works
Explanation:
its fairly simple if a medicine, antibiotic in this case is not changed over time then the thing it is fighting will learn how to ignore it to where it no longer works as the species adapt and change the antibiotics must to otherwise there will be no effect.

Which property of water makes it most suitable for transport in eukaryotic organisms ?
Water is a very important transport medium for living organisms because of its solvent properties and because it remains a liquid over a large range of temperatures. The cohesion (stickiness) between water molecules means that a very tall thin column of water can be supported before it breaks. Water's extensive capability to dissolve a variety of molecules has earned it the designation of “universal solvent,” and it is this ability that makes water such an invaluable life-sustaining force. On a biological level, water's role as a solvent helps cells transport and use substances like oxygen or nutrients.

Mitosis results in which of the following?
A. Two cells with different genes.
B. Two cells with identical genes.
C. Four cells with different genes.

In mitosis, the sister chromatids of each chromosome seperate so each daughter cell takes one chromatid from each chromosome
why do you think are the reasons why only few seeds germinate
Answer:
The germination of a seed can eventually be affected by temperature, humidity and oxygen. Generally, the seeds remain viable longer at low temperatures, a humidity range of 3% to 20% and an environment with low partial pressure of oxygen. If some of these factors are not met, the seed can age or eventually germinate.
Explanation:
Seeds are the main reproductive organ of the vast majority of higher terrestrial and aquatic plants. They play a key role in the renewal, persistence and dispersal of plant populations, the regeneration of forests and ecological succession. In nature the seed is a staple food source for many animals. Seed germination often takes place on the surface of the soil, so the balance between the gain of soil moisture and its loss by transpiration to the atmosphere determines when the seed becomes saturated with moisture and begins to germinate.
The reasons why only few seeds germinate are as a result of some factors such as temperature, availability of water, depth of plant, presence of plant hormone (Gibberellin) in the seed. etc
Seed Germination is a process after seed dormancy where seeds sprout and develop into a new young plant. The reason why some seeds germinate and others do not are some of the following:
Temperature: For the germination of seed to occurs, seed needs to undergo a moderate amount of soil temperature. The cotyledon of the seedling gets destroyed when the seeds are being exposed to an extreme soil temperature. This is why most seed doesn't thrive in the deserts.
Availability of water: The soil in which seeds need to be planted must be moist and contain have a moderate amount of water holding capacity for the survival of the seed plant. The moderate amount of water holding capacity can be seen in humus soil.
Presence of plant hormone: The presence of Gibberellin in seeds helps the activation of the cotyledon to begin the germination process after the seed has absorbed water from the soil. In seeds where the enzymes are absent, such seeds do not germinate.

you have two bean burritos with the same ingredients. One burrito weighs 0.3 pounds, while the other weighs 0.5 pounds. After microwaving each of them for one minute, which burrito will be hotter? Explain your answer.
Answer:
the one that weighs less
Explanation:
the one that weighs less has less of the amount of ingredients in it which takes less long to cook and heats up faster
Answer:
0.3 pounds
Explanation:
I say that because since there is less weight on one of them, it doesn’t have to be cooked as long, or else it may get cooked TOO uh since it weighs less, while the other one may be cooked perfectly since there is more to cook.

Appraise the importance of the role plants play in the water cycle
Answer:
The correct answer is - holds water in their body plays a role as evapotranspiration.
Explanation:
Plants play important role in a hydrologic cycle or water cycle as they absorb water from the ground. They utilize this water for their cellular function and the rest of the water is released into the atmosphere.
The process is known as transpiration or in the hydrologic cycle evapotranspiration as water exits the plant body in the form of vapor or droplets. This helps the plant to cool its body and also helps to available for the atmosphere again in pure form. It

What is the difference between small, controlled lab experiments versus an ecosystem-scale experiment?
Answer: the number of variables
Explanation:
The difference between small, controlled lab experiments versus an ecosystem-scale experiment is the number of variables.
What is an experiment?A technique used in science to create a discovery, test a hypothesis or prove a known fact.
Lab experiments are done in the lab with a limited amount of variables as there is limited space available.
The ecosystem-scale experiment is performed on large scale and with many variables.
Thus, the difference is the number of variables.

Before the widespread use of antibiotics, there were very low levels of antibacterial resistance. As antibiotic use has grown, so has the number of antibiotic resistant bacteria. WHY do you think this has occurred?
Answer:
This is because antibiotic resistance can be caused by bacteria getting the ability to be unaffected by the antibiotics Also, people not taking their medication for the entire duration exposes the bacteria to the antibiotic and makes it stronger. Also, when people overuse antibiotics and mutations occur, the bacteria becomes antibiotic resistant.
