why good packing is necessary for fruit and vegetable​

Answers

Answer:

Given the fact that all fruits and vegetables are highly perishable crops, choosing the right fruit and vegetable package can be vital for farmer's survival on the market. The main function of a package is to maintain fruits and vegetables, in a way that will preserve their quality and extend storage life.

Packaging fresh fruits and vegetables is one of the more important steps in the long and complicated journey from grower to consumer. Bags, crates, hampers, baskets, cartons, bulk bins, and palletized containers are convenient containers for handling, transporting, and marketing fresh produce.

In the two-hybrid screening technique, what type of protein is separated into two different domains to determine if two other proteins attached to these domains will interact

Answers

Answer: Transcription factor

Explanation:

In the two-hybrid screening technique, the type of protein that is separated into two different domains to determine if two other proteins attached to these domains will interact is called the transcription factor.

Transcription factors are the proteins that helps in the conversion of DNA into RNA or their transcription. Transcription factors simply consist of a large number of proteins, that initiate are used in regulating gene transcription. It should be noted that a characteristics of the transcription factors is the possession of DNA-binding domains.

Choose a specific site for further study where eutrophication is a problem (such as Chesapeake Bay, the Baltic Sea, or the Gulf of Mexico). List some sources of nitrogen and/or phosphorous to the water body and describe some of the ecological problems due to eutrophication at this specific site.

Answers

Explanation:

Due to the commercial farming activities in the MidWest, fertilizers and pesticides are usually washed away by precipitation and drain into the Gulf of Mexico. These elements (mainly nitrogen and phosphorus) offer much nutrients for algae causing them to thrive into algae blooms. Bacteria then find ‘fodder’ in dead algae breaking them down for energy sources. The bacteria, mostly aerobic, take up most of the oxygen from the water as they thrive. This makes the waters of the Gulf hypoxic hence the other marine organisms such as fishes cannot thrive. Actually, the ecosystem dies and the region is recognized as a' dead zone'.

The drug 2,4-dinitrophenol (DNP) destroys the proton gradient across the inner mitochondrial membrane. What would be the effect of incubating isolated mitochondria in a solution of DNP

Answers

Answer:

This question lacks options, options are:A) Oxygen would no longer be reduced to water. B) No ATP would be made during transport of electrons down the respiratory chain. C) Mitochondria would show a burst of increased ATP synthesis. D) Glycolysis would stop. E) Mitochondria would switch from glycolysis to fermentation.The correct answer is B)

Explanation:

The main mechanism of ATP production takes place in our mitochondria, which are cellular organelles, and this occurs when molecules of coenzymes or reduced prosthetic groups, coming from the process of catabolism of nutrients, are oxidized with molecular oxygen (which becomes in water), leading to the production of ATP. DNP works by increasing heat production in cells through a process known as decoupling. Dinitrophenol is an ionphoric compound that cuts mitochondrial ATP production circuits. This cessation of ATP production through the mitochondria leads to an increase in metabolic rate (as the substrate is used at a higher rate so that cytosolic ATP can sustain life) and subsequent weight loss.

If humans cannot see ultraviolet waves, how can ultraviolet light be used to gather evidence of a crime? Ultraviolet light detects the presence of radioactive substances. Ultraviolet light shows cold areas as blue and warm areas as red. Ultraviolet light causes substances to fluoresce and give off visible light. Ultraviolet light transmits information to AM and FM radio receivers.

UV light can be used to gather evidence of a crime because Ultraviolet light causes substances to fluoresce and give off visible light.

What is Ultraviolet Light?

Ultraviolet light refers to one of the components of the electromagnetic spectrum between visible light and X-ray.

Visible light is the only electromagnetic wave that can be seen by humans, hence, UV radiation cannot be seen by humans but can be used to detect crimes.

Ultraviolet light causes substances to fluoresce and hence, give off visible light that can then be seen by humans.

First off, radioactive materials that may have been utilised to commit a crime are frequently found using ultraviolet light. For instance, radioactive materials may have been used in a bombing to cause the explosion.

What is the region for radioactive substances ?

Even though they are invisible to the eye, these radioactive substances can be found using ultraviolet light. This can assist detectives in proving a crime was committed and locating the offenders. Second, you may use ultraviolet light to spot cool and warm spots at a crime scene.

Warm zones will show as red and cold areas as blue. This can help identify if a weapon was used or whether a fire was ignited. Additionally, it can It can also be employed to locate bodies or trace a bullet's course.

Finally, compounds that fluoresce and emit visible light when exposed to UV radiation can be found using this technology. This may be used to find biological evidence, including blood, semen, and other substances.

Additionally, it can be used to find chemical substances that might have been involved in criminal activity. Finally, ultraviolet light is a potent tool for obtaining criminal evidence. It can make things glow and emit visible light, reveal cold and warm zones, and detect radioactive materials. All of these characteristics can aid investigators in establishing the existence of a crime and locating the offenders.

The energy used to pump hydrogen ions from the mitochondrial matrix across the inner membrane and into the intermembrane space is derived from:________

a. ATP hydrolysis
b. reactions in the electron transport chain
c. decreasing the pH in the mitochondrial matrix
d. splitting water to form oxygen and protons

Answers

Answer:

b. reactions in the electron transport chain

Explanation:

Oxidative phosphorylation, which is the process described in this question, is the third stage of cellular respiration which occurs in the MITOCHONDRION of eukaryotic cells. In this stage of oxidative phosphorylation, which encompasses electron transport chain (ETC) and chemiosmosis, ATP is synthesized.

The ATP is synthesized when protons (H+) move from the mitochondrial matrix into the intermembrane space, forming, a proton pump. The series of electron transfers (reactions) that occur in the complexes of the ETC provides the ENERGY to pump the protons/hydrogen ions out of the matrix, which creates the electrochemical gradient required for ATP synthesis with the help of ATP synthase.

Hormones that are secreted by one endocrine gland (i.e., anterior pituitary gland) and control the secretion of a hormone from another endocrine gland (i.e., adrenal gland) are generally called _____________ hormones.
A. tropic
B. glucocorticoid
C. activation
D. blood releasing

Answers

Answer:

A. tropic

Explanation:

Generally, hormones are chemical messengers that are secreted in a particular location and transported to another location to effect a physiological response. However, some set of hormones secreted by an endocrine gland functions in stimulating or regulating the secretion of other hormones by another endocrine gland. These group of hormones are called TROPIC HORMONES.

As stated in this question, the anterior pituitary gland, which is considered to be the "MASTER GLAND" secretes an hormone that controls the secretion of another hormone by adrenal gland. The hormone secreted by the PITUITARY GLAND is a TROPIC HORMONE. An example of tropic hormone is ADRENOCORTICOTROPIC HORMONE (ACTH) secreted by anterior pituitary gland.
