B there is 7 electrons
An atom of nitrogen has (B) seven electrons.
In an atom in neutral state, number of electrons are equal to the number of protons. Since nitrogen has an atomic number of 7, which indicates the number of protons in its nucleus, it also has seven electrons to balance the positive charge of the protons and maintain an overall neutral charge.
Electrons are subatomic particles carrying a negative electrical charge. It is one of the fundamental particles that make up atoms, along with the protons as well as the neutrons. Electrons are a part of the family of elementary particles known as leptons. The movement of electrons within materials is responsible for electrical current flow and the generation of electromagnetic fields.

Scientific reasoning requires a circular way of thinking based on gathering and evaluating evidence.
True or False? If false what words make this statement true.
Answers
Scientific reasoning does not require a circular way of thinking, but rather a linear and iterative approach known as the scientific method. This involves making observations, forming a hypothesis, conducting experiments, evaluating evidence, and refining or discarding the hypothesis based on the results. These steps are repeated as necessary until a satisfactory answer is found.
Explanation:The statement that 'scientific reasoning requires a circular way of thinking based on gathering and evaluating evidence' is False.
Scientific reasoning actually requires a linear and iterative way of thinking, known as the scientific method. This involves making observations, forming a hypothesis, conducting experiments, gathering and evaluating evidence, and refining or discarding the hypothesis based on the results. Steps in the process are repeated as necessary until a satisfactory answer or explanation is found.
For instance, a scientist studying the effects of a new drug might start by observing its effects on lab rats, forming a hypothesis on how it might affect humans, conduct experiments to collect data, and then analyze that data to make conclusions. If the data does not support the hypothesis, the scientist would then refine the hypothesis and repeat the process.

please and thanks!
Answers
Answer:
A. Felsic
Explanation:
The rock would be classified as a FELSIC rock based on its appearance.
To classify a rock based on its appearance, we would rely more on the features we can observe when we look at it. Some of the features are colour and mineral grains. We can also use its feel, cleavage, and some other physical properties.
Looking at the picture, the rock is light coloured. The mineral grains also have a fine texture because the mineral boundaries cannot easily be resolved by naked eyes.
A light coloured igneous rock is said to be FELSIC with a rich composition of silica and feldspars. Mafic igneous rocks are usually dark and have low silica contents.
From the texture of the mineral grains, we know the rock is an extrusive rock. It must have formed on the surface or very close to the surface. This implies that, the minerals could not grow into larger crystals. They cooled rapidly on encountering surface temperatures.
A rock of this type is a Rhyolite. The intrusive equivalent is granite. Granite differs from Rhyolite because they have large mineral crystals. They are both felsic.

Answers
Answer:
The answer is
aerobic respiration and the products of that are Carbon Dioxide and Water.
Glucose and oxygen react to form ATP. Water and carbon dioxide are released in the form of byproducts.
What is cellular respiration?Cellular respiration is a sequence of chemical processes that break down glucose to generate Power, which can then be used as energy to power a variety of reactions all through the body.
Cellular respiration consists of three major steps: glycolysis, the citric acid cycle, and oxidative phosphorylation.
Cellular respiration is the process by which organisms (animals and plants) decompose sugar in the presence of oxygen in order to release energy in the form of ATP. As a byproduct of this process, carbon dioxide and water are produced.
Thus, during culture of living tissues, with glucose and adequate oxygen, the products of cellular respiration will be water and carbon dioxide.

What domain and kingdom do all invertebrate animals belong to
Answers
Answer:
Domain: eukaryotic
Kingdom: Animal
Explanation:
The Animalia kingdom constitutes the group of eukaryotic, heterotrophic, multicellular and tissue organisms, characterized by their capacity for locomotion, their embryonic development and the absence of chlorophyll. Animalia is a kingdom comprised in the Eukaryota domain.
Taxonomically, eukaryotic, is the domain (or empire) to which the organisms formed by cells with a true nucleus belong.
Invertebrate animals belong to the Eukarya domain and the Animalia kingdom. They account for about 95 percent of Animalia species. The largest phylum within this group is Arthropoda, which makes up about 85 percent of all known species.
Explanation:All invertebrate animals belong to the domain Eukarya and the kingdom Animalia. Invertebrates, which include animals without a backbone, make up approximately 95 percent of all species in this kingdom. This group encompasses a diverse range of species from 32 different phyla, perhaps most notably the phylum Arthropoda, which comprises around 85 percent of all known species and is dominated by invertebrates like insects, spiders, and crustaceans.
The domain Eukarya is characterized by organisms that have cells with a nucleus and other membrane-bound organelles. The kingdom Animalia, within this domain, includes all eukaryotic, multicellular, heterotrophic organisms that ingest their food and often develop into motile creatures with a fixed body plan. Among the distinctive features of members of the animal kingdom are the presence of differentiated tissues such as nerve, muscle, and connective tissues.

In which location would be rate of soil erosion most likely be higher than the rate of soil formation? A. A river delta B. A steep slope C. A tropical area with moderate rainfall d. A temperature forest
Answers
Answer:
B. A steep slope
Explanation:
The rate of erosion is the highest on barren lands and on steep slopes. The steep slopes are much more easy to erode because the gravity is pulling downwards, and the angle of the slope is helping that a lot. Also, the steeper the slope is, the less vegetation there is, thus the soil usually is not protected from erosion. When there's rain, snow, stronger winds, they manage to pull down the soil with ease as there's nothing that is an obstacle to stop them. That results in gradual leveling up of the slope, constantly losing on height, and eventually being totally flattened.
Final answer:
The rate of soil erosion is likely to be higher than the rate of soil formation on a steep slope due to more runoff and less vegetation to hold the soil in place.
Explanation:
The location where the rate of soil erosion would most likely be higher than the rate of soil formation is B. A steep slope. This is because soil can only develop where surface materials remain in place and are not frequently moved away by processes such as mass wasting. Steep slopes usually have more soil erosion due to several factors: more runoff of rainwater, less water infiltration, and less vegetation to anchor the soil. This results in little or no soil as the formation cannot keep up with the erosion. Other locations like river deltas, tropical areas with moderate rainfall, and temperate forests have mechanisms that help in soil accumulation or experience a balance between soil formation and erosion.

Final answer:
Lichens are used as indicators of air quality due to their sensitivity to pollutants, with their health and abundance being used to monitor environmental conditions. Their decline signals increased air pollution, while their presence indicates cleaner air. They also have ecological and historical significance.
Explanation:
Lichens are excellent biological indicators of air quality due to their extreme sensitivity to pollutants, particularly nitrogenous and sulfurous compounds. These organisms lack roots, thus they absorb water and nutrients over their entire surface area, making them especially vulnerable to pollutants dissolved in rainwater. The U.S. Forest Service and National Park Service utilize the health and abundance of lichen populations in an area to monitor air quality. When lichens decline or disappear from an area, it is often a sign that the air is heavily polluted. Conversely, their presence usually indicates cleaner air conditions.
