which of the following is not a process in the nitrogen cycle?
Answer:
give the option too
Nitrogen is present in the environment in a wide variety of chemical forms including organic nitrogen, ammonium (NH+
4), nitrite (NO−
2), nitrate (NO−
3), nitrous oxide (N2O), nitric oxide (NO) or inorganic nitrogen gas (N2). Organic nitrogen may be in the form of a living organism, humus or in the intermediate products of organic matter decomposition. The processes in the nitrogen cycle is to transform nitrogen from one form to another. Many of those processes are carried out by microbes, either in their effort to harvest energy or to accumulate nitrogen in a form needed for their growth. For example, the nitrogenous wastes in animal urine are broken down by nitrifying bacteria in the soil to be used by plants. The diagram alongside shows how these processes fit together to form the nitrogen cycle.

how does the size of a hydrocarbon molecule affect the viscosity of a hydrocarbon?
Answer:
Fuels with large hydrocarbon molecules are more viscous than fuels with small hydrocarbon molecules
Explanation:
Viscosity refers to runniness of a liquid. Fuels with large hydrocarbon molecules are more viscous as longer chains of large hydrocarbon molecules are easily entangled. Fuels with small hydrocarbon molecules are comparatively viscous as shorter chains of small hydrocarbon molecules are less likely to become entangled.

inherited traits are controlled by genes and the complete set of genes within an organism's genome is called its phenotype. The complete set of observable traits of the structure and behavior of an organism is called its phenotype. These traits arise from the interaction of its phenotype with the environment.
What's the most common type of mutation observed in living populations, and what impact does it have on natural selection?
The most common type of observed mutation is a neutral mutation. This mutation doesn't impact natural selection in any noticeable way since it doesn't impact the fit of that organism. Since neutral mutations convey no advantage, they generally must spread in a population through drift. Many also will disappear through drift.

What is the purpose of natural selection?
Answer:
differential survival ( more info below)
Explanation:
Natural selection is the differential survival and reproduction of individuals due to variations in phenotypes. This is a central process of evolution, a transition in the heritage characteristics characteristic of the population over centuries. Variation exists in all populations of organisms.

Draw conclusions: Substances that contain carbon and are produced by living things are
called organic. Examples of organic materials are sugar, blood, protein, and fat. Other materials, like water, carbon dioxide, oxygen, and ammonia, are called inorganic.
Some living things, called producers, can produce the organic materials they need (like food) from inorganic matter. All other organisms are consumers; they consume organic matter since they cannot make it themselves.
Do your results show you that trees are producers or consumers?
its a gizmo lol
Answer: Yes.
Trees are producers
Explanation:
Trees are producers because they have the ability to produce organic materials like sugar.
Trees have green pigments called chlorophyii on their leaves, this pigment trap light energy from the sun and uses carbondioxide and water to photosynthesized in order to produce sugars. Trees undergo a process called photosynthesis which is a process where by green plants uses light energy from sunlight with water and carbondioxide to produce sugars.
Once trees produce sugars, other organism cannot synthesized their own food on their own, so they largely depend on trees for organic materials. Theses organisms are herbivores and sometimes omnivores.
Therefore, Trees are producers.

(Fill in the blank) In comparing DNA and structural characteristics between plant species, the similarities that appear may indicate a ____________________ __________________between them. (Think of evolution)
Answer:
(Fill in the blank) When comparing DNA and structural characteristics between plant species, the similarities that appear can indicate a genetic adaptation to a particular environment, between them.
Explanation:
The evolution of the spice indicates that there were changes in the environment where these plants were able to adapt genetically, and not only that but they transmitted it in their generations, that is why many manifest the same genetic code, if this gene was inherited among them it means that the species EVOLVED.
Otherwise, those genes that generate benefits for the plants but are not transmitted in the parent plants will not be considered as an evolutionary change of the species but individual of the plant.
The genetic changes produced by modifications in the environment translate into phenotypic changes, thus generating a more suitable species with a greater chance of survival.
