Which cell organelle is like the construction site, where proteins are built? Which cell organelle packages and transports the protein to the food processing plant?


vacuole; endoplasmic reticulum


nucleus; mitochondria


cell membrane; lysosome


ribosomes; golgi bodies

Answers

Ribosomes; Golgi Bodies

- Ribosomes use instruction (RNA) from the nucleus to build proteins. This makes it like a construction site.

- The Golgi Bodies receives, packages, and ships the products of the ER through the cell. This makes it like a food processing plant.

Which best explains the genetic similarities between species? A. More closely related species will have identical dna B. More closely related species will have fewer dna similarities C. More closely related species will have more similarities in dna D. There is no link between the relationships of species and their dna

Answers

Answer:

C

Explanation:

The correct answer would be that more closely related species will have more similarities in DNA.

The DNA stores the genetic information of organisms and contains a set of instructions that defines how organisms look. It is usually used to delimit species with closely related species of organisms having similar DNA. The more related species are, the more similar their DNA would be and vice versa because the similarity in the DNA of organisms is often used as an indication of descending from a common ancestor.

The correct option is, therefore, C.

Genes are the hereditary unit of life, which carries the information from parent to daughter cells. The organisms belonging to the same species will have the same genetic sequence.

The correct answer is:

Option C. More closely related species will have more similarities in DNA

The DNA stores the genetic information of the organisms and codes for the traits of the organism.

The genes delimit the species' relativity of the organisms. The species that are closely related will have more similarities in the genetic sequence.

The similarity of the genes or DNA is often used as an indication of descending of species from a common ancestor.

Therefore, option C is correct.

A sequence of chemical processes known as cellular respiration convert glucose into ATP, which can then be used as energy for a variety of bodily functions.

What is cellular respiration?

Glycolysis, the citric acid cycle, and oxidative phosphorylation are the three basic processes that take place during cellular respiration. The citric acid cycle happens in the mitochondrial matrix, oxidative phosphorylation happens on the inner mitochondrial membrane, and glycolysis happens in the cytoplasm.

Glucose, ATP, and NAD+ are the initial reactants and ATP and H2O are the end products of cellular respiration. The enzymes phosphofructokinase-1, pyruvate dehydrogenase, and isocitrate dehydrogenase control the rate of cellular respiration.

Disorders that interfere with cellular respiration typically affect one or more of the enzymes necessary for it, such as succinyl-CoA synthase or pyruvate kinase.

Therefore, A sequence of chemical processes known as cellular respiration convert glucose into ATP, which can then be used as energy for a variety of bodily functions.

Hello?? Can anyone help me??! PLEASE

Answer:

The temperature is staying the same. In the graph when it shows solid/liquid and liquid/gas, the temperature stays the same until it changes. This is because it reached it's melting point/vaporizing point. For example, a solid gets heated up, it then reaches it's melting point but it can't go higher than that because it isn't fully a liquid yet, once it's a liquid it will then continue to rise in temperature.

Compare and contrast lactic acid fermentation and alcoholic fermentation. Include examples of organisms that use each type of fermentation.

Answers

Answer:

Lactic acid fermentation happens in our muscle cells when we are exercising feverishly, while alcoholic fermentation is used in yeast cells and is what leads to beer, bread, and wine.

Explanation:

The comparison between lactic acid fermentation and alcoholic fermentation-

1. Lactic Acid Fermentation:

pyruvate changes to lactic acidused by muscle

2. Alcoholic fermentation:

pyruvate changes to alcohol and carbon dioxideused in bread by yeast, wine, and biofuels

Lactic acid fermentation is a metabolic process by which glucose or other six-carbon sugars are converted into ATP which is cellular energy and the metabolite lactate, which is the lactic acid in solution.

Alcoholic fermentation is a biological process by which sugar is converted into alcohol and carbon dioxide with heat.both happen under anaerobic conditions and produce a little amount of ATP.Alcoholic fermentation gives CO2 while lactic acid does not.
