Which of the following choices correctly shows an example of the way energy flows in an ecosystem? A. Rattlesnake to Hawk to Kangaroo Rat to Fungus to Cactus B. Fungus to Hawk toRattlesnake to Kangaroo Rat to Cactus C. Cactus to Kangaroo Rat to Rattlesnake to Hawk to Fungus D. Cactus to Fungus to Kangaroo Rat to Hawk to Rattlesnake
Answers
ANSWER:
C. Cactus to Kangaroo Rat to Rattlesnake to Hawk to Fungus
EXPLANATION
Living organisms in an ecosystem obtain energy by feeding on one another. As one organisms feeds on the other, ENERGY FLOWS. However, the flow of energy is UNIDIRECTIONAL. The flow of energy is represented by a FOOD CHAIN where the arrow signals which organism is feeding on which.
According to this question, a typical example of energy flow in a terrestrial ecosystem is as follows:
Cactus → Kangaroo rat → Rattlesnake → Hawk → Fungus
In the above food chain, energy flows as cactus plant (producer) is fed on by kangaroo rat (primary consumer), which is fed on by rattlesnake (secondary consumer), which is fed on by hawk (tertiary consumer). Hawk is decomposed by fungi (decomposer) when it dies. Energy flows in this direction.
Hence, an example of the way energy flows in an ecosystem is represented by Cactus to Kangaroo Rat to Rattlesnake to Hawk to Fungus

6. How are excess salts that accumulate in cells transferred to the blood stream so they can be removed from the body? Explain how this process works in terms of tonicity.
Answers
Answer:
Tonicity is the concentration of a solution compared to another, with regards to the number of solutes in these solutions. Too many solutes in a cell may cause them to be hypertonic hence absorb water too much water and lyse. Therefore, these solutes are excreted to the blood-stream through active transport and facilitated diffusion. These solutes are then excreted by the kidneys. If they are not excreted, the osmotic pressure (due to the inflow of water to the bloodstream by osmosis) may cause high blood volumes being pumped by the heart hence high blood pressure
Explanation:
Tonicity is the concentration of a solution compared to another, with regards to the number of solutes in these solutions. Too many solutes in a cell may cause them to be hypertonic hence absorb water too much water and lyse.
What is excreted from the blood stream?The solutes are excreted to the blood-stream through active transport and facilitated diffusion. These solutes are then excreted by the kidneys. If they are not excreted, the osmotic pressure due to the inflow of water to the bloodstream by osmosis may cause high blood volumes being pumped by the heart hence high blood pressure.
Osmosis is the net movement of water across a semi-permeable membrane from an area of lower gradient concentration to an area of higher gradient concentration. On the other hand, tonicity is the ability of an extracellular fluid to make water move into or out of a cell through osmosis. A solution's tonicity is related to its osmolarity or the total concentration of the solutes in a solution.
Therefore, Tonicity is the concentration of a solution compared to another, with regards to the number of solutes in these solutions.

Answers
Answer:
Compare two organism on the physical features and mode of nutrition.
Explanation:
Organisms are classified in groups and sub-groups on the basis of similarities and differences. so in order to compare two organisms, start with the similarities that are present between them. If similarities are more so they belong to the same group or if differences are more than both are placed in different groups. for classification, see the physical appearance of organism, mode of nutrition and habitat etc. If organisms are identical, they belong to the same species, if one or two characters are different so their genus will be same but specie is different. In zoo animals are different from the animals which is present in garden so compare the physical features of zoo and garden animals.

During the process of translation in a eukaryote messenger RNA is spliced in the nucleus. amino acids are synthesized by RNA polymerase. transfer RNAs are joined together by a large enzyme complex. ribosomes must be imported into the nucleus. mRNA interacts with ribosomes in the cytoplasm.
Answers
Answer:
mRNA interacts with ribosomes in the cytoplasm.
Explanation:
The correct option would be that mRNA interacts with ribosomes in the cytoplasm.
Translation involves the use of genetic codes in mRNA to synthesize amino acids that are eventually linked together by polypeptide bonds to form proteins.
During translation, the mRNA synthesized in the nucleus is transported into the cytoplasm where it gets attached to the ribosome and another RNA - the tRNA. The codons on the mRNA eventually match with the anticodon of the tRNA with the later releasing the amino acid that corresponds to each codon.
Hence, the correct answer out of all the options is that mRNA interacts with ribosomes in the cytoplasm.

Explanation:
When activated, the receptor most likely prompting the production of saliva is the taste receptor. When food enters the mouth, the salivary glands produce the saliva upon the sensation of taste.
Answer:
Taste receptors.
Explanation:
When activated, the receptor most likely prompting the production of saliva is the taste receptor. When food enters the mouth, the salivary glands produce the saliva upon the sensation of taste. The secretion of saliva (salivation) is mediated by parasympathetic stimulation; acetylcholine is the active neurotransmitter and binds to muscarinic receptors in the glands, leading to increased salivation.

The hydrosphere is made up of all the water on the planet, including the water found below the surface and in the atmosphere. A planet's hydrosphere may be liquid, vaporous, or composed of ice. The three surface water bodies on Earth are oceans, lakes, and rivers.
What are some non examples of hydrosphere?It comprises all surface waters that are liquid or frozen, groundwater that is contained in soil or rock, and atmospheric water vapor. The hydrologic cycle continuously circulates almost all of these waters. In wells and aquifers, it can also be found underground as groundwater.
Within the hydrosphere, water circulates in a cycle. Clouds contain water that eventually falls to Earth as rain or snow.
Therefore, Rivers, lakes, and seas are where this water gathers. The cycle is then restarted by its evaporation into the atmosphere. The water cycle refers to this.

Answers
Answer:
Although there is no diagram attached to this question but it can be answered based on the general knowledge of photosynthesis. The answer is:
H2O and light
Explanation:
Photosynthesis is a unique phenomenon that occurs in the Chloroplast of plant cells. It is the process by which plants and other autotrophs obtain their energy source (food) in the presence of sunlight. Photosynthetic process occurs in two distinct stages viz: light dependent reaction and light independent reactions.
The light dependent reaction, as the name implies, is dependent on light to occur. It occurs in the Thylakoid membrane of the Chloroplast, where a photon of light is captured by the Chlorophyll pigment and the energy is used to split molecule of water in a process called PHOTOLYSIS OF WATER. The transfer of electrons across the thylakoid membrane creates a proton pump, which is used to generate ATP and NADPH. NADPH and ATP are electron and energy carriers respectively which enters into the light independent stage in order to synthesize glucose (sugar).
In a nutshell, the inputs of the light dependent stage are LIGHT from the sun, and water (H2O), which provides the proton and electron when split.

Answers
Answer:
You can only hunt dear (example) for only sertin times of the year because when the doe's have their fans people want them to get big before they shoot them
Answer:
Animal populations can change from one season to another, so it’s important to restrict hunting to seasons when the population is high. Such a restriction helps prevent a severe drop in population, which could threaten the species. It’s also important to limit hunting during breeding seasons to increase the possibility of offspring reaching adulthood.

Which type of microscope would be the best tool to use to view the surface of a bacterial cell? Why?
Answers
Answer:
Electron Microscope
Explanation:
The maximum theoretical resolution of images created by light microscopes is ultimately limited by the wavelengths of visible light. Most light microscopes can only magnify 1000×, and a few can magnify up to 1500×, but this does not begin to approach the magnifying power of an electron microscope (EM), which uses short-wavelength electron beams rather than light to increase magnification and resolution.
-The electron microscope can achieve a much greater resolution than that obtained with the light microscope because the wavelength of electrons is shorter than that of light.
An Electron microscope is the type of microscope that would be the best tool to use to view the surface of a bacterial cell.
What is a Microscope?A microscope may be defined as an instrument that utilizes the arrangements of lenses to make an enlarged image of a small object.
An Electron microscope produces a higher resolution of bacterial cells as compared to a standard light microscope. This is because electrons possess a much shorter wavelength than visible light.

Glaucoma is a leading cause of blindness. Studies have linked a common form of glaucoma to three genes and more than 20 genetic loci. Which best describes glaucoma?
Answer
(A) - a recessive trait that requires multiple recessive alleles to be expressed
Explanation:
Glaucoma is a polygenic trait influenced by the alleles of several genes.
Polygenic phenotypic traits are those influenced by many genes, which interact to shape the phenotype. Polygenic traits exhibit a bell-shaped distribution in a population (i.e. they have a continuous distribution). Some examples of polygenic traits include, among others, height, body shape, skin color, weight, etc.A polygenic trait that is also affected by environmental factors is known as a multifactorial trait.In conclusion, glaucoma is a polygenic trait that is influenced by the alleles of several genes.
