what is the role of microorganisms in food preservation?​

Answers

Answer 1

Answer:

Preservation usually involves preventing the growth of bacteria, fungi (such as yeasts), and other microorganisms.

Explanation:

Nature uses microorganisms to carry out fermentation processes, and for thousands of years mankind has used yeasts, molds and bacteria to make food products such as bread, beer, wine, vinegar, yogurt and cheese, as well as fermented fish, meat and vegetables reduce food spoilage.

Can someone help me with the order of the carbon cycle ?

Answers

Answer:

First what is it? Carbon cycle is, nature's way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms.

1.Carbon moves from the atmosphere to plants. In the atmosphere, carbon is attached to oxygen in a gas called carbon dioxide (CO2). Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth.

2.Carbon moves from plants to animals. Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too.

3.Carbon moves from plants and animals to soils. When plants and animals die, their bodies, wood and leaves decays bringing the carbon into the ground. Some is buried and will become fossil fuels in millions and millions of years.

4.Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants need to get rid of carbon dioxide gas through a process called respiration.

5.Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas. Each year, five and a half billion tons of carbon is released by burning fossil fuels. Of this massive amount, 3.3 billion tons stays in the atmosphere. Most of the remainder becomes dissolved in seawater.

6.Carbon moves from the atmosphere to the oceans. The oceans, and other bodies of water, absorb some carbon from the atmosphere. The carbon is dissolved into the water.

What type of reaction does catalase facilitate- synthesis or decomposition? Why?

Answers

Catalase is a common enzyme found in nearly all living organisms exposed to oxygen (such as bacteria, plants, and animals) which catalyzes the decomposition of hydrogen peroxide to water and oxygen.

Catalase is a common enzyme found in nearly all living organisms exposed to oxygen (such as bacteria, plants, and animals) which catalyzes the decomposition of hydrogen peroxide to water and oxygen.

What is catalase?

An enzyme called catalase causes (catalyzes) the process by which hydrogen peroxide is broken down into water and oxygen.

Catalase, which is widely distributed in organisms that live in the presence of oxygen, inhibits the buildup of peroxide, which is continuously created by multiple metabolic reactions, and shields cellular organelles and tissues from harm. Catalase is primarily found in the liver of mammals.

Numerous industrial uses exist for catalase. It is used with other enzymes in the food industry to preserve foods, make particular dishes and beverages, and preserve foodstuffs.

Therefore, Catalase is a common enzyme found in nearly all living organisms exposed to oxygen (such as bacteria, plants, and animals) which catalyzes the decomposition of hydrogen peroxide to water and oxygen.

In Drosophila the anterior-posterior axis is established by

a. The distribution of the RNA-binding transcription factor called bicoid and the protein nanos localized in the anterior and posterior poles of the embryo, respectively

b. The distribution of a gene that codes for an RNA-binding protein called nanos localized in the anterior pole of the embryo and a transcription factor called bicoid localized in the posterior pole of the embryo

c. The distribution of a gene that codes for an RNA-binding protein called nanos localized in the posterior pole of the embryo and a transcription factor called bicoid localized in the anteror pole of the embryo

d. The distribution of the RNA-binding transcription factor called bicoid and the protein nanos localized in the posterior and anterior poles of the embryo, respectively

Answer:

c. The distribution of a gene that codes for an RNA-binding protein called nanos localized in the posterior pole of the embryo and a transcription factor called bicoid localized in the anterior pole of the embryo

Explanation:

When the Drosophila zygote develops, it goes through different stages until it gets to the blastula stage. At this point, there are pole cells that determine the axis of the organism -the anteroposterior and the dorsoventral axis-.

A two hours old embryo has already determined its two axes. A ten hours old embryo has already determined its body segments. And from there, each of them develops a structure that turns to be their identity.

Different genes determine the polarity of the egg.

Dorsoventral genes place in the superior and inferior parts of the egg and determine the development of dorsal and ventral tissues.

The same happens with anteroposterior genes.

The BICOID genes place in the anterior part of the egg and activate the hunchback genes that determine the development of the head and the thorax. The Bicoid mRNA distributes in the anterior region of the egg.The NANOS gene reprimes the hunchback genes, which promoted the development of the posterior structures of the body. The Nano mRNA places in the posterior region of the egg, and Nano proteins distribute in this area.

The polarity genes of the egg are genes of maternal effects.

While the bicoid and nano genes are expressed in the ovary, the hunchback gene is expressed in the embryo. This last one is activated or inhibited by the foreign ones.

Bicoid and nano genes gradient regulate the expression of the gap, pair-rule, and segment polarity genes.

Answers

Planet X
Explanation:
The orbital radii of planet X is the smallest which means that is closest to the sun. The distance to the star determines the temperature of the planet. Closer the planet, more likely it would have higher temperature. So planet X has highest temperature most likely.
In the solar system, there is exception, mercury is closest to sun but Venus which is the second planet from the sun has highest temperature. This is because mercury has no atmosphere and Venus has very thick atmosphere which traps the solar radiation and heats up.

Answer:

x and y

Explanation:

x and y have the smallest orbital radius so they are likely to be inner planets while w and z have bigger orbital radius so the probability of them being inner planets is low.

Answers

Answer:

Hi how are you doing today Jasmine

Answer:

Yes, an animal can adapt into a new species through a process called speciation. Speciation occurs when a population of animals undergoes significant changes over time, leading to the formation of a new species that is different from the original one.

Explanation:

REASON

The main reason for this adaptation and the emergence of a new species is natural selection. Natural selection is the process by which individuals with advantageous traits are more likely to survive and reproduce, passing on those traits to their offspring. Over many generations, these advantageous traits become more common in the population, while individuals without these traits become less common.

When a population of animals faces different environmental conditions or habitats, it can create diverse selection pressures. Some individuals may possess traits that allow them to better adapt to these new conditions, giving them a higher chance of survival and reproduction. As these advantageous traits become more prevalent in the population, they can eventually lead to reproductive isolation.

Reproductive isolation occurs when individuals from the original population can no longer mate and produce fertile offspring with individuals from the newly adapted population. This can happen due to genetic differences and changes that have accumulated over time. When reproductive isolation is complete, the two populations are considered separate species.

SUMMARY

Overall, the process of adaptation and the formation of new species is driven by natural selection, which favors traits that enhance an organism's chances of survival and reproduction in specific environments. Over time, these changes can accumulate, leading to the development of distinct species.

7. Pedialyte is a beverage which contains the same concentration of ions (K , Cl-, and Na ) as found in the plasma. Gatorade and Powerade mimic (although are not identical to) Pedialyte. Therefore, we might expect that consumption of Pedialyte should not significantly alter the osmolarity of the blood. How would you expect the urine production rate in the Pedialyte group to compare to that of the water group

Answers

Answer:

Less urine production.

Explanation:

The urine production rate in the Pedialyte group is lower as compare to that of the water group because the presence of K, Cl-, and Na ions. The precise combination of electrolytes and sugars in Pedialyte helps in restoring fluid levels and the nutrients in the body that are lost through sweating, urinating, or vomiting and diarrhea. We know that the presence of sodium ions regulation water and electrolyte balance in the body so there is less urine produced by taking Pedialyte group.

The  urine production rate in the Pedialyte group to compare to that of the water group -

Pedialyte group - decreased

water group - increased.

The rate of urine output is the urine production in a unit of time. The normal range of urine output is 800 to 2,000 milliliters per day if you have a normal fluid intake of about 2 liters per day.

Drinking Pedialyte increases the ion concentration in the plasma that causes hyperosmolarity. This is sensed by the hypothalamus and releases ADH that leads to more fluid absorption in later DCT and collecting tubules that leads to decrease urine output. On the other hand, if you drink water, hypoosmolarity in blood plasma which does not sense by the hypothalamus and does not release ADH, and the urine output is more than the previous case.

Thus,  

The urine production rate in the Pedialyte group to compare to that of the water group -

Pedialyte group - decreased

water group - increased.

Why does the the right testicle hang lower than the left?? PLease help i will be thank (Sorry english second language if your wondering why my grammar might be a little off. I formally apologize for any confusion the weird spelling. )

Answers

it is entirely normal for one testicle to be bigger than the other. Many people find that the right testicle is slightly larger and the left hangs lower. A difference in size is usually nothing to worry about, though it can occasionally indicate a problem.

This is perfectly normal and nothing to worry about. Either side may be slightly larger or hang lower. But be sure to tell a parent (who will let your doctor know) if you have any pain, swelling, or lumps in your testicles.

When a vein in a testicle becomes enlarged, it's called a varicocele. Varicoceles affect up to 15 percent of males. Like varicose veins in your legs, varicoceles may appear bulgy under the skin of your scrotum. They tend to form in the left testicle because the vein on the left side hangs lower.

A researcher performs an experiment to test a hypothesis that involves the nutrients niacin and retinol. She feeds one group of laboratory rats a daily diet of precisely 125.6 units of niacin and 5,400 units of retinol. She uses two types of commercial pellet food. Food A contains 0.86 units of niacin and 30 units of retinol per gram. Food B contains 0.66 units of niacin and 40 units of retinol per gram. How many grams of each food does she feed this group of rats each day

Answers

Answer:

- 100 grams of food A (x)

- 60 grams of food B (y)

Explanation:

According to this question, the group of laboratory rats are being fed a daily diet of:

- 125.6 units of niacin and 5,400 units of retinol

Let x represent the number of grams needed for food A.

Let y represent the number of grams needed for food B.

This means that:

Food A: Niacin = 0.86x, Retinol = 30x

Food B: Niacin = 0.66y, Retinol = 40y

Since there are 125.6 units of niacin fed to the rats in total, then;

0.86x (A) + 0.66y (B) = 125.6

Since there are 5400 units of retinol fed to the rats in total, then;

30x (A) + 40y (B) = 5400

Solving these two equations simultaneously using elimination method:

0.86x (A) + 0.66y (B) = 125.6 ........(eqn 1)

30x (A) + 40y (B) = 5400 ............ (eqn 2)

Multiply eqn 1 by 30 and eqn 2 by 0.86

30 × 0.86x + 0.66y = 125.6

0.86 × 30x + 40y = 5400

25.8x + 19.8y = 3768 ............ (eqn 3)

25.8x + 34.4y = 4644 ........... (eqn 4)

Subtract eqn 3 from eqn 4

14.6y = 876

Divide both sides by 14.6

y = 876/14.6

y = 60

Substitute value for y (60) into eqn 2

30x + 40y = 5400

30x + 40(60) = 5400

30x + 2400 = 5400

30x = 5400 - 2400

30x = 3000

x = 3000/30

x = 100

Therefore, she feeds the group of rats 100grams of food A (x) and 60 grams of food B (y).
