Mineral composition and vegetation are two other environmental elements that could be responsible for the variations in stickleback populations between Bear Paw Lake and Frog Lake. This prediction is tested by measuring the water sample for mineral composition and determining the vegetation present.

Sticklebacks are ponds, lakes, ditches, and rivers inhabiting tiny, elongated fish. Some populations of these stickleback fish underwent physiological changes when they transitioned from surviving in the ocean to freshwater habitats. Pelvic spine loss was one prominent adaption.

The other environmental factors that are affecting the differences between pelvic spine in Bear Paw Lake and Frog Lake stickleback populations are the lake's mineral composition and vegetation.

To measure and test this prediction, first, we have to take water samples from both lakes and then measure the calcium and other minerals in them. The lake that has high calcium helps to form pelvic spines.

Another test is to measure vegetation to hide. The more vegetation present in the lake, there is more possibility the fishes can hide from the predators.

The property of matter that causes this law to hold true is inertia. The inertia of an object is proportional to its mass. Inertia, however, is not the same as mass or momentum.

Physical and chemical properties are present in all matter. Physical properties, such as mass, color, and volume, are characteristics that scientists can measure without changing the composition of the sample under investigation (the amount of space occupied by a sample). Chemical properties describe a substance's characteristic ability to react and form new substances; they include flammability and corrosion susceptibility. A pure substance has the same chemical and physical properties in all samples. Pure copper, for example, is always a reddish-brown solid (a physical property) that dissolves in dilute nitric acid to form a blue solution and a brown gas (a chemical property).

Answer:

Monosaccharides and polysaccharides are both types of carbohydrates, but they have some key differences. Monosaccharides are simple sugars that cannot be broken down into smaller sugars, examples of monosaccharides are glucose and fructose. Polysaccharides, on the other hand, are complex carbohydrates made up of long chains of monosaccharides. Examples of polysaccharides include starch and glycogen.

Carbohydrates and lipids are two different types of biomolecules. Carbohydrates are made up of simple sugars and are an important source of energy for living organisms. Lipids, on the other hand, are a diverse group of biomolecules that include fats, waxes, and oils. They are not as important as a source of energy as carbohydrates but are essential for energy storage, insulation, and cell membrane structure.

Saturated fats and unsaturated fats are both types of lipids. Saturated fats have a high proportion of saturated fatty acids, which means that their carbon atoms are fully bonded to hydrogen atoms. They are typically solid at room temperature, and are usually derived from animal sources. Unsaturated fats have a high proportion of unsaturated fatty acids, which means that some of their carbon atoms are not fully bonded to hydrogen atoms. They are typically liquid at room temperature, and are usually derived from plant sources. Unsaturated fats are considered to be healthier than saturated fats, as they can help lower cholesterol levels and reduce the risk of heart disease.

Explanation:

Monosaccharides are simple carbohydrates made up of one sugar molecule, while polysaccharides are complex carbohydrates made up of multiple sugar molecules. Carbohydrates are molecules composed of carbon, hydrogen, and oxygen, while lipids are molecules composed of carbon, hydrogen, and oxygen, as well as nitrogen, phosphorus, and/or sulfur. Unsaturated fats have at least one double bond between their carbon atoms, while saturated fats have only single bonds between their carbon atoms. Unsaturated fats are usually liquid at room temperature, while saturated fats are usually solid. Unsaturated fats can also be beneficial to health, while saturated fats can increase the risk of heart disease.

C and D. Two valence electrons are shared and valence electrons are shared between oxygen atoms.

A double bond between a carbon atom and two oxygen atoms (a molecule of carbon dioxide) is a covalent bond, not an ionic bond. In covalent bonding, atoms share electrons in order to fill their valence electron shells and achieve stability. In the case of a double bond between a carbon atom and two oxygen atoms, the carbon atom shares two valence electrons with each oxygen atom. This results in each oxygen atom having a full valence electron shell, and the carbon atom having four electrons in its valence shell. The sharing of these electrons creates a stable molecule of CO2.

Disruptive selection can be considered adaptive in certain situations. When the environment favors individuals with extreme traits, it can lead to the formation of two distinct subpopulations.

This can increase the overall genetic diversity of a population and increase the chances of disruptive selection survival of the population in case of a change in the environment. For example, in a population of birds, birds with very long beaks may be better able to disruptive selection reach deep flowers for food, while birds with very short beaks may be better able to crack open seeds. Birds with beaks of intermediate length may not be able to perform either task as well and may be at a disadvantage.  However, disruptive selection can also be maladaptive if the environment changes and the extreme traits that are being favored are no longer beneficial to the population.

Explanation:

This is the diagram of a cranium/skull.

The given statement “The molecular and fossil records are in agreement with the appearance of animals.” is false because due to the rarity of fossilization, the fossil record is thought to be incomplete. The remains must be covered by sediments and left undisturbed for thousands of years in order for fossilization to take place.

One of the most important periods in the evolution of life was the emergence of animals, although the timing of this transition is still poorly understood. Animals are thought to have evolved and started to diversify more than 100 million years before the first conclusive Cambrian metazoan fossil evidence. Closer examination finds that, contrary to popular belief, there is less of a divergence between clock estimations and the fossil record. The presence of the crown-representatives of the majority of animal phyla in the Neoproterozoic is not predicted by contemporary clock analysis.
