Which cell has the GREATEST surface area to volume ratio?
O Chicken egg
O Skin cell
O Bacterial cell
O Liver cell
Answers
The cell with the greatest surface area to volume ratio is the smallest cell, in this case, the bacterial cell.
As a cell increases in size, the proportional increase in volume is higher than that of its surface area. This tells us that the bigger a cell becomes, the lower its surface area to volume ratio will be.
The chicken egg is just one large cell, the largest cell produced by most animals. The skin and liver cells are much smaller, measuring roughly 25-30 micrometers. However, the smallest of the list by far is the bacterial cell, measuring a mere 1-3 microns. This size tells us that the greatest surface area to volume ratio belongs to the bacterial cell.

(-Since you are alive and breathing, your respiratory system is also involved.)
-Getting up involved the muscular and skeletal systems, which allow movement and bodily structure, and the nervous system, which commands the muscles and bones to move.
-Eating and drinking involves the digestive system again as saliva and enzymes break down the food travelling from the mouth to the stomach.

How to bring the information from the nuclear DNA to the place of protein synthesis?How to convert this DNA information into amino acids and then into proteins?Explanation:
The genetic information is found in the DNA and depends on a specific sequence of nitrogenous bases. This information is transcribed into the messenger RNA, whose base sequence is organized into triplets and codons, each of which encodes an amino acid, as well as establishing the pattern for starting and stopping the synthesis of a protein.
How to bring the information from the nuclear DNA to the place of protein synthesis?The DNA must be transcribed into messenger RNA (mRNA), a process that occurs in the nucleus of the cell. mRNA leaves the nucleus and travels to the cytoplasm, where amino acid synthesis will take place.
How to convert this DNA information into amino acids and then into proteins?Once in the cytoplasm mRNA binds to ribosomes, structures in charge of translating the sequence of nitrogenous bases RNA to synthesize amino acids. The set of ribosomes and rough endoplasmic reticulum are in charge of the assembly of amino acids to produce peptides and proteins.
A large number species on Earth become extinct during a short time period about 65 million years ago. Based on this pattern of extinction, which is the MOST likely cause
Answers
Answer and Explanation:
During the whole biota history, there occurred extinctions due to different reasons.
During the Cretaceous, which took place between 145-65 million years ago, there occurred a massive extinction that eliminated most of the species on the Earth. Many of the characteristic groups of this period were affected. Dinosaurs, Plesiosaurs, Ammonites, Tricodonts, Cycas, Gynkgos, Conifers, the recent angiosperms, birds, and mammals.
The extinction was caused by the volcanic eruptions, and the unusual fall of many different asteroids, which caused important changes on the Earth´s surface. The consequent climatic change was what ended affecting all the species directly. The extinction was gradual, although it occurred in a short geological lapse of time.

Answers
Answer:
Carbon Cycle
Everything You'll Have Covered
What role do producers, consumers, and decomposers play in the carbon cycle?
~ Producers synthesize their food through photosynthesis using energy from sunlight and carbon dioxide from the air. Their respiration returns carbon dioxide to the atmosphere. Consumers use the food produced by producers for energy. Their respiration also returns carbon dioxide to the atmosphere. Decomposers break down plant and animal waste products. They also break down dead plants and animals. The decomposing process releases carbon dioxide gas into the atmosphere.
How do fossil fuels and volcanic activities contribute to the carbon cycle?
~ When fossil fuels are burned, carbon dioxide is released into the atmosphere in the form of gas. When volcanoes erupt, carbon dioxide that was in the magma passes into the atmosphere as carbon dioxide gas.
How is carbon returned to the Earth and sea in the carbon cycle?
~ Carbon is returned to the Earth and sea in the form of precipitation after carbon dioxide mixes with rain and snow. Erosion is another way that carbon is returned to the sea. When shellfish die, the carbon that was in their shells collects at the bottom of the ocean and eventually forms sedimentary rocks.
Give one example of a human activity�that could disrupt the�carbon�cycle�as well as the consequences of this disruption.
~ Burning fossil fuels can disrupt the carbon cycle, since they increase carbon dioxide in the air, which can lead to environmental problems such as acid rain.
Photosynthesis is the process by which plants produce their food in the presence of sunlight that is solar energy with the use of carbon dioxide and water. The breakdown is the mechanism by which plants give their carbon dioxide back.
What is end product of photosynthesis ?The end products of photosynthesis are glucose and oxygen that is given back to the atmosphere.
In plants, photosynthesis is the process by which plants prepare their food in the presence of sunlight and glucose is made thus this is the way by which plants are preparing their food and in the case of plants glucose is stored in the form of starch.
With the reactions going on when the cellular respiration reactions are going on at that time the reactions produce enough of carbon dioxide which is given back to the atmosphere thus this dependency helps to interpret the mutual relationship.

O Visible traits are the same for each member of a family.
Question 11
Answers
A hereditary trait is one that is genetically determined. Inherited traits are passed down from parent to child according to the rules of Mendelian genetics. Most traits are not strictly determined by genes, but rather are influenced by both genes and the environment....
Explanation:
The characters that offspring inherits from its parent is called genetic traits. It passes from parent to child in the form of a genome inside the cell nucleus.
The correct statement about the genetic traits of humans:
Option A. Visible traits depend on the dominant and recessive forms of genes from each parent.
This can be explained as:
Recessive traits are not visible in the presence of dominant traits and get masked.The dominant trait does not always get transferred from each parent. Even a single parent can pass a dominant allele.Visible traits are not the same and common for family members as crossing over and recombination occurs.Therefore, dominant and recessive allele from parents decides the phenotype.
