there are many contributors to malnutrition and hunger; however, one factor stands out among all others. what is the primary cause of malnutrition?
Irrespective of the fact that hunger and malnutrition has many contributors, one of the leading factors that is regarded as the primary cause of malnutrition is: poverty.
Malnutrition and hunger are two terms that describe the inability of an individual to meet his or her nutritional requirement.
Irrespective of whatever definition that is given to malnutrition and hunger, the fact still remains that such an individual suffering from malnutrition and hunger is not getting the adequate nutrition they need.
There are several factors that contribute to malnutrition and hunger, however, a leading cause that seem to be the genesis of malnutrition and hunger is poverty.
Poverty can be defined as a state of lacking the means to meet basic daily needs which includes good nutrition.
Most of the countries that are very impoverished have high percentage of their populace suffering from malnutrition and hunger.
When the means is not available to get adequate and quality food, hunger and malnutrition will always prevail against every other contributors.
In summary, irrespective of the fact that hunger and malnutrition has many contributors, one of the leading factors that is regarded as the primary cause of malnutrition is: poverty.Learn more here:

which combination of cells and growth factors would serve as the control group?
Answer:
These stimuli, called growth factors, are naturally occurring proteins specific to certain groups of cells in the body. They include nerve growth factor, epidermal growth factor, and platelet-derived growth factor.
Explanation:
Hope this helps.
Growth factors are defined as the proteins that bind to specific receptors, which activate the cascade of signal transductions. The growth factors lead to proliferation, apoptosis, and development.
Different types of growth factors stimulating the signal transduction are:
1. Nerve growth factor is controlled by the gene NGF. It provides the instructions to make the beta protein, which is important for the survival and development of the nerve cell.
2. Epidermal Growth Factor is a type of factor that stimulates cell development and cell proliferation. It generally stimulates the fibroblasts and epithelial cells.
3. Platelet-derived growth factor regulates cell division and growth. These factors help in healing and repairing the wound and walls of the damaged blood vessels.
Thus, the growth factors when bound to specific cell receptors control the various activities of the cells.

Answer:Madagascar Pochards
Explanation: The Madagascar Pochard, or sometimes known as the Madagascan pochard, is a very rare diving duck of the genus Aythya. Thought to be extinct in the late 1990s, individuals of the species were recovered in 2006 near Bemanevika, Madagascar, at Lake Matsaborimena. The species is only found in Madagascar's interior marshes, where it is endemic. The sole wild populations are currently found in Lake Sofia and Lake Matsaborimena. Meanwhile, there are slightly over 50 pochards at Bemanevika.

Stella described protein synthesis as a process that makes the necessary proteins for the human body to function. She
explained the process in the following steps.
1. DNA is transcribed into mRNA.
2. Amino acids form a chain.
3. The amino acid chain is folded into a protein in the endoplasmic reticulum.
What step did Stella miss in her explanation?
(1 point)
O Polypeptide chains express gene traits.
O tRNA delivers the DNA to the ribosome.
hy
O DNA is replicated into two daughter cells.
O mRNA is translated into amino acids.
The step of protein synthesis missed by Stella would be the translation of mRNA into amino acids.
The process of protein synthesis can essentially be divided into 2, namely:
TranscriptionTranslationDuring transcription, genetic information on DNA is transcribed into mRNA. Once this is done, the genetic codes in mRNA are then translated to their respective amino acids and linked by peptide bonds.
The polypeptide bond undergoes further processing such as folding in the endoplasmic reticulum.
Thus, before amino acids can form a polypeptide chain, they must first be translated from genetic codes in mRNA.

Why does a plant produce more sugar after summer?
Answer:
Sunlight = Energy
Explanation:
Plants have chlorophyll that uses sunlight from the sun to create energy.
The energy is then used to change carbon dioxide from the air into sugars like glucose. The plant transports sugars into the tissues like roots, flowers and fruits so it can grow.
Answer:
Plants have chlorophyll that uses sunlight to gather energy. The energy is then used to change carbon dioxide from the air into sugars like glucose and fructose. ... They transport sugars throughout the plant and supply it to tissues like roots, flowers and fruits that depend on this sugar to grow.

A certain sugar has no change in color when tested with Benedict’s solution. Can you tell what type of sugar it is? Explain.
Answer:
a certain sugar has no change in color when tested with benedict solution. can you tell which saccharide it is? no because it could be poly or disaccharide. what is the chemical formula for a polysaccharide molecule that contains 4 glucose molecules?
Sucrose
Sucrose (table sugar) contains two sugars (fructose and glucose) joined by their glycosidic bond in such a way as to prevent the glucose undergoing isomerization to an aldehyde, or fructose to alpha-hydroxy-ketone form. Sucrose is thus a non-reducing sugar which does not react with Benedict's reagent.
Explanation:
Sugars which give no color in Benedicts test are non-reducing sugars. Sucrose, a non reducing sugar does not undergo a color change in Benedict's test.
What is Benedict's solution?Benedict's solution is a chemical reagent containing copper sulphate pentahydrate and mixtures of sodium carbonate and sodium citrate. It is used to test the presence of reducing sugars.
A positive Benedicts test gives color change of blue to brick red precipitate whereas, non-reducing sugars does not give a positive result.
Sucrose contain fructose and glucose, they do not reduces the copper ion in Benedict's solution because there are no free aldehydes or ketones in sucrose.
Thus, sucrose does not reduce and will not give a color change in Benedict's test.

Nucleic acids are the organic compounds, which control the making of proteins and contain the genetic material to pass to the next generation.
• The two prime kinds of nucleic acids are ribonucleic acid or RNA and deoxyribonucleic acid or DNA.
• The genetic material found in all the living species is the DNA, which is found in the nucleus of eukaryotes and is found in free-floating form in the cytoplasm in prokaryotes.
• This genetic material is passed on from generation to generation.
• The other kind of nucleic acid is RNA, which is mainly involved in the synthesis of proteins. The types of RNA, that is, tRNA, mRNA and rRNA takes place in the synthesis of protein and its regulation.
