Protein synthesis is a vital function in all cells. Identify two cell structures involved in protein synthesis and state how each structure functions in protein synthesis. Cell Structure Function in Protein Synthesis
Answer:
Ribosome and rough endoplasmic reticulum
Explanation:
As the name implies, protein synthesis, involves the synthesis of proteins in a cell. Cellular structures in a cell called organelles are responsible for this function. These organelles include ribosome and rough endoplasmic reticulum.
The ribosome is an organelle found in all cell types and is the site for the synthesis of proteins in the cell. The ribosome is where translation (process of synthesizing amino acid chains from mRNA) occurs. The chains of amino acid later becomes the protein.
The Rough endoplasmic reticulum (RER) gets it "roughness" from the fact that RIBOSOMES are attached to its surface. Due to this, the RER functions in the synthesis of proteins. The RER is involved in the production, folding and packaging of proteins in eukaryotic cells. The RER processes the polypeptide produced by the ribosome into proteins that are carried to varying destinations.

Hello!!! Princess Sakura here ^^
Explanation:
1.) Exercising reduces blood glucose concentrations, so when you don't exercise it'll increase.
2.) When you exercise your muscles work harder and then your body will start to need more oxygen and produces more carbon dioxide.
3.) As you exercise, the insulin sensitivity increases, so your muscle cells are able to take up glucose during and after activity.

Power plants were built in the Imperial Valley as a means to harness power from geothermal resources. However, the construction of these power plants has led to the loss of habitat for burrowing owls. How can engineers and scientists solve the problem of habitat loss for burrowing owls and other wildlife?
Some of the ways Engineers and scientist can solve the problem of habitat loss are :
Planting more trees for animals and birds that live on treesCreation of Bird sanctuaries around the power plantsTo compensate for the loss of habitat faced by the birds and animals that were original inhabitants of the imperial valley just like the burrowing owls, scientists and engineers can create artificial bird sanctuaries just around the power plant to encourage the burrowing owls to resettle given that it will look like a familiar habitat to them.
Planting more trees in areas with an average amount of trees will also encourage the resettlement of animals and birds that live on trees because of the abundance of trees.
Hence we can conclude that Some of the ways Engineers and scientist can solve the problem of habitat loss are : Planting more trees for animals and birds that live on trees, Creation of Bird sanctuaries around the power plants.

In this unit, you have learned how your mouth and stomach can be used together to help break down the food you eat. In this project, you will be writing two paragraphs. The first paragraph you will explain what happens to the food you eat once it reaches your lips. Make sure to include what happens in your mouth, esophagus, stomach, small intestine and large intestine. In the second paragraph write which food you would rather eat and why, a candy bar or an apple. Be sure to include how both options affect your body. Don’t forget to read through the rubric below, so you will know what you will be graded on.
Answer:
; (1.8 meters per minute)
Step-by-step explanation:
Use dimensional analysis to solve this problem.
The proper units of conversion are given in parentheses on this question: 100 cm = 1 m.
Start with the given value, 3 centimeters/1 second.
Convert this rate to meters/minute by multiplying 3 cm/1 sec by 1 m/100 cm.
The top and bottom units should cancel out, so that's how you know to put the cm units on the bottom to cancel out with the 3 cm on the top.
Multiply the fractions together. The "cm" units cancel out.
Now you want to make the bottom units = minutes. There are 60 seconds in 1 minute, so you can use to multiply with .
The "seconds" unit cancels out, so you are left with meters on the top and minutes on the bottom. Multiply the fractions together.
We want the rate to be meters per minute (1), so completely simplify this fraction and divide the fraction by (100/100), so the denominator is 1 min.

Answer:
IM SORRY THIS IS SO LATE!!!
Explanation:
The first step of digestion begins the moment the food on your plate touches your lips and goes into your mouth, believe it or not, teeth are part of the digestive system! Your teeth help chew and grind the food into smaller pieces, which makes it easier to swallow. Saliva then continues to break down the food further by converting starches to sugars, with the help of the enzyme that is in saliva called amylase. Once this occurs the food particles that are left will be passed down to the esophagus. The esophagus is a muscular tube that is on average ten inches long and about one inch wide. It passes food down by using many different contractions to force food and liquids into the stomach. When the food reaches your stomach, it begins to churn and move which ends up grinding the food. To do this the stomach produces juices that break down the tissues of meat. This stomach juice is known as gastric juice, it is a mixture of acid, enzymes, and water. The stomach empties out a small amount of food every thirty minutes to the small intestine. The food stays in the small intestine for approximately ten hours. During this time, the food slowly dissolves into the blood. The blood then carries the digested food to all parts of the body. The inside of the small intestine is a wall made of hundreds of small fingers called villi. Each villus has its own tube to take in the dissolved digested food. Since some food remains after the food has been digested this food is passed on to the large intestine. These waste remains are passed out of the body through the lower part of the colon known as the rectum. Studies have shown that having a good diet is especially important to have a healthy colon, some foods to eat that are good for you are celery, lettuce, and cabbage.
I would personally eat the apple since a nice, juicy, and crispy apple sounds much more appetizing than a chocolate candy bar. The reason I would eat an apple is because if you are looking for a healthy snack and compare the nutrition facts it is surprisingly a closer call than I anticipated. The apple has 19 grams of sugar and the candy bar has 21 grams of sugar. Going off that the apple is a better choice. If we go off carbohydrates there are both 25 grams, so that would be by just choice if we go off that. If we look at all the nutrition facts and long-lasting effects in 2018 Journal of Food Composition and Analysis showed that processed chocolate had unsafe levels of cadmium and nickel. This is a huge long-term affect that can cause permanent damage in your body that you will not realize right away. When you eat an apple a day though there are many more positive health benefits for example, apples help with keeping a healthy good balanced gut health. They also provide 14% of the recommended daily use of vitamin C. Now a chocolate candy might solve your cravings for sugar but in the future, there are way more positive effects if you eat an apple instead of a chocolate. Considering all these factors I would rather eat an apple.

Without greenhouse gasses in the atmosphere , would the earths temperature be warmer colder or about the same?
Answer: Way colder
Explanation:
The greenhouse gases in the atmosphere are found to be responsible for the increase in temperature. If the atmosphere does not contain greenhouse gases then the earth's temperature will be colder than that with greenhouse gases.
What are greenhouse gases?A greenhouse gas absorbs and emits radiant energy within the thermal infrared range which causes the greenhouse effect. Greenhouse effect leads to increase in the atmospheric temperature of the earth.
The main gases responsible for the greenhouse effect are carbon dioxide, methane, nitrous oxide, and water vapor, and fluorinated gases.
The natural greenhouse effect is caused by the greenhouse gases which are present naturally, and is vital to life. In the absence of the natural greenhouse effect, the Earth would be approximately 33°C cooler.
