Answer:
Essential nutrients cannot be synthesized by the human body but are required for optimal functioning. Therefore. They must be obtained from food. Omega-3 fatty acids are prime examples.
You consume macronutrients (water. proteins, carbohydrates, and fats) in large quantities as opposed to micronutrients which you consume in small quantities
Dehydration can develop very quickly when exercising in hot/humid weather conditions.
Proteins are also called 'bodybuilders" due to their function within the body. Amino acids are the building blocks of proteins.
Explanation:
Essential nutrients are those nutrients that are required for the proper functioning of the body but cannot be synthesized by the body. They are obtained from external sources such as vegetables or synthesized artificially in the laboratories. Micronutrients as the name implies are taken in small amounts. Examples are the different types of vitamins.
Dehydration occurs when a person loses a good amount of water through sweating or urination. It can easily occur while exercising in hot weather conditions. Proteins repair the cells in our body and are, therefore, rightfully referred to as bodybuilders. Amino acids form proteins.

Looking at the following organisms and their diets, place them into a food chain. Make sure you have arrows that show the correct flow of energy.
Aardvark: omnivore diet
Ant: herbivore diet
Grass: autotroph
Hyena: carnivore diet
Answer:
Grass > Ant > Aardvark > Hyena
Explanation:
The grass is autotrophic, which means it can produce its own food It does so using water, carbon dioxide, and light energy from the sun. The organisms in this food chain rely on other organisms for food.
The ant is a herbivore that consumes the grass for energy. The aardvark consumes both plants and animals (omnivore), so it can consume the ants. The hyena is a carnivore, meaning it only eats animals, such as the aardvark.
What is a major obstacle in cellular respiration? It is limited by the low amount of energy stored in a glucose molecule It is an exergonic reaction, with much of the energy lost as heat, which potentially might damage cells It is an inefficient reaction and doesn’t provide eukaryotic cells with enough energy It requires oxygen to be actively pumped against its concentration gradient into cells
Answer:
It is an exergonic reaction, with much of the energy lost as heat, which potentially might damage cells
Explanation:
Cellular respiration is an important process carried out by the cells of living organisms in order to supply energy needed for their various cellular functions. Cellular respiration generally involves the breakdown of the stored energy in glucose molecules (in the presence of absence of oxygen).
However, since the process of cellular respiration releases energy as chemical energy (ATP) and majority as heat energy, it is said to be an EXERGONIC REACTION i.e energy-releasing. This hear energy released can damage living cells, which is a major setback to cellular respiration.

move the Earth's lithospheric plates?
A. gravity acting on the edges of plates and friction between the plate and the asthenosphere
B. friction between the plate and the asthenosphere and pressure of magma on the
edge of the plate
C. gravity acting on the edges of plates and convection in the mantle
D. convection in the mantle and pressure of magma on the edge of the plate
Answer:
C. gravity acting on the edges of plates and convection in the mantle
Explanation:
A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere. Therefore, the option (C) is correct.
What are lithospheric plates?Plate tectonics is the generally accepted scientific theory that considers the Earth's lithosphere to comprise a number of large tectonic plates which have been slowly moving since about 3.4 billion years ago.
Earth's crust, called the lithosphere, consists of 15 to 20 moving tectonic plates. The plates can be thought of like pieces of a cracked shell that rest on the hot, molten rock of Earth's mantle and fit snugly against one another.
In plate tectonics, Earth's outermost layer, or lithosphere—made up of the crust and upper mantle—is broken into large rocky plates. These plates lie on top of a partially molten layer of rock called the asthenosphere.

Reliability and probability in forensic tests are important. When you look at matching a paint chip to a specific car, you are working to increase the probability that the right car matching your paint chip evidence will be found. Reliability means you have practiced and applied the correct procedures and processes for all your evidence testing, and you know you can trust the results. Some forensic tests are more reliable than others, and the best type of test or tests to use will usually depend on the kind of evidence that is present. If all types of evidence were present at a crime scene, which type of test would you choose based on its reliability and probability of accuracy? Identify which test you would choose and provide a detailed argument as to why you feel it has a high level of reliability in comparison to other types of evidence. Your answer should be at least two paragraphs in length and should include solid arguments for your choice. There is no wrong choice, just be sure to provide a convincing argument.

Explanation:
Phototropism is the term that describes the growth of a plant toward any light source. School-age children often demonstrate this principle by showing how a newly sprouted seed, for example, leans in the direction of a nearby light bulb. Heliotropism is the process that describes how a plant specifically tracks the sun’s movement across the sky.

5. Besides being part of the composition of bone, why else do mammals need calcium?
Answer:
It's important for the contracting muscle
Explanation:
Besides being part of the composition of bones, calcium is needed by mammals for the following processes:
Formation of skeletons and teeth.Muscle contraction.Regulation of normal heart rate and nerve functions. Blood clotting. What is Calcium in living organisms?Calcium in living organisms may be defined as an important nutrient that all living organisms require, including humans in order to develop various organs like teeth and bones as well as for metabolic processes.
Apart from being part of the composition of bones, calcium is also required for the proper development of teeth and skeletons. The movement of calcium ions plays an essential role in the contraction of muscles.
The influx of calcium ions into the cells of the heart significantly enhances the heart rate of an individual in the range of 1.6 to 14.10 mm.
It also plays a critical role in blood clotting.
Therefore, it is well described above.
