Answer:
A. Limits to resources exist for a population
Explanation:
<em>The explanation that fits the growth curve would be that there exist limits to the resources available for the population.</em>
As a result of limited resources, a population is prevented from reaching its biotic potential and confines the population growth model to logistic rather than exponential.
The limited resources keeps the population around the carrying capacity of the environment, that is, the maximum population size an environment can support based on the resources it has.
<u>A newly established population usually experience a short period of exponential growth. As a result of continuous competition for resources, the population becomes limited and begins to oscillate around the carrying capacity of the environment.</u>
The correct option is A.
Answer:
Body temperature
Explanation:
We use body temperature as homeostasis parameter in the lab.
Homeostasis can be described as a self regulating mechanism used by the body systems for stability maintainable so as to adjust to several conditions that are important for survival.
The way the body controls the body temperature in humans is a good description of homeostasis
Answer:
Heterotrophic
Explanation:
A heterotroph is an organism that cannot produce its own food, instead taking nutrition from other sources of organic carbon, mainly plant or animal matter.

Answer:
Most people are familiar with carbohydrates, one type of macromolecule, especially when it comes to what we eat. To lose weight, some individuals adhere to “low-carb” diets. Athletes, in contrast, often “carb-load” before important competitions to ensure that they have enough energy to compete at a high level. Carbohydrates are, in fact, an essential part of our diet; grains, fruits, and vegetables are all natural sources of carbohydrates. Carbohydrates provide energy to the body, particularly through glucose, a simple sugar that is a component of starch and an ingredient in many staple foods. Carbohydrates also have other important functions in humans, animals, and plants.
Carbohydrates can be represented by the stoichiometric formula (CH2O)n, where n is the number of carbons in the molecule. In other words, the ratio of carbon to hydrogen to oxygen is 1:2:1 in carbohydrate molecules. This formula also explains the origin of the term “carbohydrate”: the components are carbon (“carbo”) and the components of water (hence, “hydrate”). Carbohydrates are classified into three subtypes: monosaccharides, disaccharides, and polysaccharides.
Monosaccharides
Monosaccharides (mono– = “one”; sacchar– = “sweet”) are simple sugars, the most common of which is glucose. In monosaccharides, the number of carbons usually ranges from three to seven. Most monosaccharide names end with the suffix –ose. If the sugar has an aldehyde group (the functional group with the structure R-CHO), it is known as an aldose, and if it has a ketone group (the functional group with the structure RC(=O)R′), it is known as a ketose. Depending on the number of carbons in the sugar, they also may be known as trioses (three carbons), pentoses (five carbons), and or hexoses (six carbons). See Figure 1 for an illustration of the monosaccharides.
