Both producers and consumers are a source of food for?

1 answer:

6 0

<em>both producers and consumers are the part of ecosystem but finally either directly or indirectly they become food of the decomposers that may be micro-organisms or the larger parasite or saprophyte ..
organisms taking food from living host are parasite while taking food from dead matter are saprophytes..</em>

Molecular Biology
This field of study deals with everything related to macromolecules, thus, what you will need for molecular biology would be something you could get proteins and nucleic acids from. Among the choices, the DNA of a pig and a calf would be the most helpful.

Comparative Anatomy
Comparative anatomy is a field of study that focuses on any similarities or differences between the anatomy or structure of different animals or species in general. Among the options, having the limb structure of a pig and a calf would allow you to practice the field since you have a structure to compare.

Developmental Biology
In this field, your concern would be how species grow and develop. For you to properly observe the growth and development, you must have the embryo of a pig and a calf. Therefore, among the options, this is the correct piece of evidence for this field.

IN SUMMARY:
Molecular Biology - Both DNA of a pig and a calf
Comparative Anatomy - Both limb structure of a pig and a calf
Developmental Biology - Embryo of a pig and a calf

Tidal fluctuations can affect the abundance of aquatic organisms in an ocean environment. which tide would have the *least* impa

Alisiya [41]

The best and most correct answer among the choices provided by the question is the third choice "neap"

Neap tides<span> occur twice a month when the sun and moon are at right angles to the Earth. When this is the case, their total gravitational pull on the Earth's water is weakened because it comes from two different directions.</span>

I hope my answer has come to your help. God bless and have a nice day ahead!

Match each definition to the appropriate term. locus

liraira [26]

I) Locus- the chromosomal site where a specific gene is located. A locus is a fixed position on a chromosome, like the position of a gene or a marker. Each chromosome carries ,many genes; human's estimated haploid (n) protein coding genes are about 20,000, on the 23 different chromosomes.

ii) Interference; the observed double crossover frequency differs from the expected double crossover frequency. Cross over interference is used to refer to the non-random placement of crossovers with respect to each other during meiosis. It results in widely spaced crossovers along chromosomes. Interference may exert its effect across whole chromosomes. As chromosomes in many eukaryotes are large, interference must be able to act over megabase lengths of DNA.

iii) Linkage- the tendency for genes located in close proximity on the same chromosome to be inherited together. Normally when two genes are close together on the same chromosome, they do not assort independently and are said to be linked. Whereas genes located on different chromosomes assort independently and have a recombination frequency of 50%, linked genes have a recombination frequency that is less than 50%.

iv) Recombination- the process by which a new pattern of alleles on a chromosome is generated. Genetic recombination is the production of offspring with combinations f traits that differ from those found in either parent. During meiosis in eukaryotes, genetic recombination involves the pairing of homologous chromosomes. This may be followed by information transfer between the chromosomes.

What do sphincter muscles do? a. Trigger hormone release. b. Control peristalsis. c. Secrete digestive juices into the GI tract.

Maksim231197 [3]

Answer:

Answer is E.

Explanation:

Generally, sphincter are circular or ring - shaped muscles, surrounding the natural opening in the body. They control the movement of substances by opening and closing through expansion and contraction.

There are many sphincter in the body, examples are

* Cardiac sphincter...found at the upper area or portion of the stomach.

* Pupilary sphincter..found in the iris of the eye.

* Glisson's sphincter...controlling the secretion of the gall bladder,pancrease and the liver.

if you wanted to test red blood cells for their ability to complete glycolysis, what compound would you try to detect

Artemon [7]

Answer:

Pyruvate

Explanation:

Glycolysis refers to the pathway through glucose is oxidized to pyruvate.

In glycolysis, a molecule of glucose passes through ten enzyme catalyzed steps to yield two molecules of pyruvate.

Step 1: Glucose is phosphorylated to form glucose-6-phosphate

Step 2: Glucose-6-phosphate is converted to fructose-6-phosphate

Step 3: Fructose-6-phosphate is further phosphorylated to form fructose-1,6-bisphosphate

Step 4: Fructose-1,6-bisphosphate is cleaved into glyceraldehyde-3-phosphate and dihydroxyacetone phosphate

Step 5: Dihydroxyacetone phosphate is converted to another molecule of glyceraldehyde-3-phosphate.

Step 6: Two molecules of Glyceraldehyde-3-phosphate are converted to two molecules of 1,3-bisphosphoglycerate

Step 7: Two molecules of 1,3-bisphosphoglycerate are converted to 3-phosphoglycerate

Step 8: Two molecules of 3-phosphoglycerate are converted to two molecules of 2-phosphoglycerate

Step 9: Two molecules of 2-phosphoglycerate are converted to two molecules of phosphoenolpyruvate

Step 10: Two molecules of phosphoenolpyruvate are converted to two molecules of pyruvate, the end-product of glycolysis.

Therefore, the presence of pyruvate molecules in red blood cells can be used to test for their ability to complete glycolysis
