Answer: The energy from the sun is the only source of energy which has the ability to sustain life on earth.
The energy pyramid states that the transfer of energy is unidirectional and it flows from the producers to the consumers.
There are different trophic levels at which the organism are found say herbivores, carnivores and top predators.
All of the organism are dependent on the producers for their source of energy.
hence, the sunlight helps autotrophs to make food and herbivores feed on them and then the carnivores animals feed on herbivores and then the top predators feed on the carnivores animals.
So, ultimate source of energy on earth is sun, which directly or indirectly provides energy to the producers and other animals.

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.

Which process does not release carbon dioxide to the atmosphere? a. Decomposition of animals b. Photosynthesis of plants c. Respiration of animals d. Respiration of plants
Answer:
Option B
Explanation:
Photosnythesis in plants involve the utilization of carbon dioxide coupled with water in the presence of sunlight to yield sugars and oxygen, so in this case, oxygen is released into the atmosphere while carbon dioxide is used up.

How does the function of the glottis help the frog survive?
Answer:
This voice box occurs in all amphibians but is anatomically most complex in frogs. The larynx exits into the trachea; the latter bifurcates into the bronchi and then into the lungs. The glottis then opens, and elastic recoil of the lungs forces the pulmonary air out and over the new air in the buccopharyngeal pocket.

The climate of a certain area is cold, and snow is
found on the ground most of the year. Equal
numbers of two populations of rabbits are
introduced into this climate by a group of
scientists. One of the populations is brown and
the other is white. Predict what will happen over
several generations.
Answer:
Explanation:
Based on the information provided within the question it can be predicted that the population of the brown rabbits will diminish over time or may even go extinct, while the white rabbit population will thrive. This is because the white rabbits fur color allows it to better blend into it's environment and hide from predators, which in term leads to their survival as opposed to the brown rabbits which have nowhere to hide in the snow.

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.

Why we use methane blue solution to check cheek cell under a microscope ?
Answer:
Explanation:
We use methane blue solution to colour the cells we place under the microscope. The solution highlights different part of the cell in different shades and allows us to observe properly. This is not possible if we just look at the cells under the microscope without anything..
Hope this helps
Answer:
Methylene blue has a string affinity for both DNA and RNA.
Explanation:
The nucleus at the central part of the cheek cell contains DNA. When a drop of methylene blue is introduced, the nucleus is stained, which makes it stand out and be clearly seen under the microscope.
primary function of the cell membrane? *
Protein synthesis
Protecting organelles
Filling space between cell organelles

Answer:
Hydrolysis
Explanation:
Answer:
Hydrolysis
Explanation:
Hydrolysis is the process of using water "hydro-" to break "lyse-" apart macromolecules. Because most molecules in the body are covalent, which is stronger in water than ionic, there needs to be a specific reaction to break them down, not just dissolution.
For example, maltose can be broken down into two glucoses by this process.

Which base is found only in RNA
Uracil is the base that is found only in RNA and is not present in DNA. In RNA, uracil replaces thymine, which is one of the four bases found in DNA. This difference in the nitrogenous bases is one of the key distinctions between RNA and DNA.
RNA stands for ribonucleic acid. It is a single-stranded molecule that is made up of nucleotides, which are the building blocks of RNA.
The nitrogenous bases found in RNA are adenine (A), guanine (G), cytosine (C), and uracil (U). But uracil is the only base found in RNA. The reason for this difference in bases is due to the fact that RNA is a single-stranded molecule, while DNA is double-stranded.
The presence of uracil in RNA allows it to form complementary base pairs with adenine, which helps to stabilize the RNA molecule.
Therefore, the nitrogenous base that is found only in RNA is uracil. This base plays an important role in RNA structure and function, allowing it to form complementary base pairs with adenine and contribute to the stability of the RNA molecule.

(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.
