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.

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.

Light microscopeElectron microscope.Fluorescence microscopes.During the 1950s, a scientist named Lysenko tried to solve the food shortages in the Soviet Union by breeding wheat that could grow in Siberia. He theorized that if individual wheat plants were exposed to cold, they would develop additional cold tolerance and pass it to their offspring. Based on the ideas of artificial and natural selection, do you think this project worked as planned
Answers
Answer:
No
Explanation:
Trofim Lysenko was a Biologist in the then Soviet Union, who did not believe in the fundamental laws of science. Selective breeding is the method developed by humans to change certain characteristics of species to desired outcomes. This is based on the fact that living things have inheritable traits encoded in genes that can be passed from one generation to another.
Lysenko did not believe in this fact. He rather believed that when exposed to the right environment, plants and animals soon become adjusted to the exposure and can then develop traits that would be passed on to their offsprings. He applied this theory of his when he exposed wheat plants to cold believing that they would develop tolerance to cold. This failed woefully and resulted in severe starvation that caused the death of millions of people in the Soviet Union.

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.

Answers
The four phases of the carbon cycle, which is vitally important for both plants and animals, are as follows:
What is carbon cycle?A sequence of environmental processes known as the "carbon cycle" involve the absorption of carbon dioxide into living tissue through photosynthesis, its release back into the atmosphere through respiration, the decomposition of extinct creatures, and the burning of fossil fuels.
1. Carbon dioxide, a type of carbon, is released into the atmosphere. Examples include combustion and breathing.
2. Plants use the carbon dioxide in the air, and following photosynthesis, they release oxygen into the atmosphere.
3. Environment-present animals consume plants and transfer carbon up the food chain. They breathe out carbon dioxide into the atmosphere. Animals and plants pass away after a specific amount of time.
4. Unless fossils of plants and animals are developed, which also contain carbon, the body of plants and animals is eaten through decomposition, returning the carbon to the environment in the form of carbon dioxide.

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.

which phase of water is the most dense and which is the least dense
Answers
Answer:
The ice form of water is most dense, and the vapor form of water is the least dense.
Explanation:
The molecular cohesion in ice is stronger than in liquid or vapor, forcing the molecules of water to remain closely bonded making it dense. The vapor form of water is weaker that liquid and ice since the molecules are nearly free roaming or loosely bonded making it not very dense.
Cheers.
The most dense phase of water is liquid water, and the least dense phase of water is ice.
As water freezes and transitions from a liquid to a solid state, the water molecules arrange themselves in a regular and more structured pattern, forming a crystal lattice.
This arrangement leads to an increase in the space between the water molecules compared to the more closely packed molecules in the liquid phase.
As a result, the density of ice is lower than that of liquid water.
This is due to the hydrogen bonding between water molecules.
When water freezes, the molecules slow down, and the hydrogen bonds stabilize, resulting in the formation of ice crystals with a less dense arrangement.
As the temperature decreases below 4 °C, the density of water decreases due to the expansion that occurs when it freezes into ice.
Thus, the most dense phase of water is liquid water, and the least dense phase of water is ice.

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.

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.
