What three variables influence bacterial growth?Some of the most significant elements that affect bacterial development include the following: concentrated nutrition Temperature. vaporized concentration.
What one element can have an impact on the development of bacteria in food?Temperature is one of the most crucial aspects to take into account when microbial development is concerned. Most of the time, increasing temperatures are positively correlated with food enzyme activity. Enzyme production is carried out by bacteria. Enzymes may contribute to rotting.

It is flu season! The flu is caused by a virus. Scientists continue to debate whether or not viruses are alive. If we consider the image of the flu virus seen here, we could say that a virus is NOT alive because https://www.usatestprep.com/modules/gallery/file.php?id=1531 for the picture
Answer: the answer is D
Explanation:
Answer: There is no cellular structure
Explanation: If we use the image to support our argument, we could say a virus s not living because there is no cellular structure. All prokaryotic cells lack a nucleus. We cannot tell, from the image, anything about its way of life.
In the early 1900s, three species of goatsbeard wildflowers, T. dubius, T pratensis, and T. porrifolius, were introduced to the United States. Each of the species had a chromosome number of 2N. In the 1930’s, a few populations of offspring from the original wildflowers were identified as having a chromosome number 4N. What does this data suggest about speciation.
A. Speciation has occurred because the original species of wildflowers produced populations of viable offspring.
B. Speciation has occurred because breeding between the offspring and original populations would not be possible.
C. Speciation has not occurred because the offspring of the original wildflowers were not introduced into a new area.
D. Speciation has not occurred because the offspring inherited identical genetic information to the original wildflowers.
Answer:
B. Speciation has occurred because breeding between the offspring and original populations would not be possible.
Explanation:
Speciation has occurred in the species due to no breeding between the offspring and original populations because the offspring and original species has different number of chromosomes in their DNA. Due to this difference in the chromosome number in the DNA, there is no chance of breeding between offspring and original species. Speciation is the evolutionary process by which populations of organism evolve with the passage of time and become different from the original species.
Examine the image that shows the folds in the lining of the small intestine. Which of the statements best describes the interaction between the small intestine and another organ based on the model shown here?
Answer: It’s C.) The increased surface area to volume ratio of the small intestine allows for the absorption of materials into the bloodstream more efficiently.
Explanation:
Two interacting systems involved in plant transport are shown here. Which statement best describes the function of xylem and phloem in transporting substances throughout the plant?
Answer:
C. Xylem transport water and nutrients from the soil to the leaves while phloem transport carbohydrates from the leaves to the rest of the plant.
Explanation:
What might occur if the stoma were all located on the top of the leaves?
Answer:
It depends on the plant and its environment. In a mesic terrestrial environment, the plant wouldn’t be optimized. Natural selection would then come into play and there would be an evolutionary trend towards stomata located on the lower leaf surface.
In the case of water lily, the lower epidermis is in contact of the water, and stomata are restricted to the upper surface of the leaf. This is an optimal solution for the plant. Natural selection will work to conserve that arrangement. In this case, stomata on the lower surface would exist at a water-air interface, and the diffusion of gasses across that interface would be glacially slow. Further, the stomata on the lower surface would present an opening where pathogens can enter the leaf.

Answer:
Well The answer you choose was wrong I think because every living being that has cells need a Nulceus in their cells or the cells won’t work. Fungi have cells and Protista also have a nucleus since it has a cell or cells.
The answer here I would think would be (c) ”many could be found in fresh water”. Fungi don’t usually appear near seas or fresh sources which in this case is a pond and protistia do.

Hello, jamesundercover06.
The first box, starting on the left, I believe, should be H2O. The second box, the one over the arrow, should be sunlight. The third box, right after the arrow, should be C6H12O6. The final box, then, should be O2. I'm pretty sure that this is right, but if it is incorrect in any way let me know and I will do my best to give you the correct answer.

4. On the basis of what criteria did Linnaeus classify “natural bodies"
into his system?
Answer:
Metamorphism is the answer
Male organisms will commonly engage in physical activity to show dominance during mating season. Male kangaroos can commonly be observed kicking one another, while bighorn rams will gather and crash their heads/rams into each other prior to mating season. This is an example of ______.
Question options:
competition
predation
commensalism
parasitism
Male kangaroos that kick one another and bighorn rams will gather and crash their heads into each other prior to mating season are examples of competition.
What is competition?Competition is a type of ecological relationship in which two organisms contend for the same resource (e.g., food).
Competition can be divided into intraspecific competition and interspecific competition.In general, intraspecific competition makes reference to competence for reproduction.In conclusion, male kangaroos that kick one another and bighorn rams will gather and crash their heads into each other prior to mating season are examples of competition.

Write a paragraph explaining the steps involved in a muscle contraction starting from the brain sending a signal to the muscle and ending with the muscle contraction.
Answer:
A Muscle Contraction Is Triggered When an Action Potential Travels Along the Nerves to the Muscles.Muscle contraction begins when the nervous system generates a signal. The signal, an impulse called an action potential, travels through a type of nerve cell called a motor neuron. The neuromuscular junction is the name of the place where the motor neuron reaches a muscle cell. Skeletal muscle tissue is composed of cells called muscle fibers. When the nervous system signal reaches the neuromuscular junction a chemical message is released by the motor neuron. The chemical message, a neurotransmitter called acetylcholine, binds to receptors on the outside of the muscle fiber. That starts a chemical reaction within the muscle.Acetylcholine Is Released and Binds to Receptors on the Muscle Membrane.
A multistep molecular process within the muscle fiber begins when acetylcholine binds to receptors on the muscle fiber membrane. The proteins inside muscle fibers are organized into long chains that can interact with each other, reorganizing to shorten and relax. When acetylcholine reaches receptors on the membranes of muscle fibers, membrane channels open and the process that contracts a relaxed muscle fibers begins:
Open channels allow an influx of sodium ions into the cytoplasm of the muscle fiber.
The sodium influx also sends a message within the muscle fiber to trigger the release of stored calcium ions.
The calcium ions diffuse into the muscle fiber.
The relationship between the chains of proteins within the muscle cells changes, leading to the contraction.

Explanation:
In many tropical rainforests, people clear land by cutting down trees and burning them. After a few years, the soil runs out of nutrients and cannot be farmed any longer. How does this affect Earth's atmosphere?
Answer:
Land will convert into desert eventually
Explanation:
When the soil gets devoid of nutrient, it will be unable to support trees, plants or vegetation of any type. Trees and plants are responsible for holding the soil tightly and prevent it from eroding.
Once there will be no nutrient in soil, there will be no trees, plants or vegetation and hence there will be no mechanism to prevent soil erosion. Thus, the soil will erode due to deforestation and the land will convert into desert eventually
