Disruptive type of selection occurs when individuals with traits at either extreme have higher fitness than those individuals in the middle. Hence option c is correct.
Natural selection happens when people with a particular genotype have a higher chance of surviving, reproducing, and passing on their alleles to the following generation than individuals with a different genotype.
When those at the upper and lower extremities of the curve are more fit than people in the middle, disruptive selection takes place. Disruptive selection targets people of an intermediate type, and it can result in the emergence of two different phenotypes.
African seed cracker birds' various beak sizes show evidence of disruptive selection. The beaks of the birds vary in size, and they eat seeds. There were two different sizes of seeds available: tiny and large.

"Red rust is one of the destructive diseases in tea plants which results adverse effect on tea yield. It is caused by a type of algae." Which discipline of Biology is related to explain the above statement? a. Mycology b. Agronomy c. Pathology d. Phycology
Answer:
C
Explanation:
The correct answer would be plant pathology.
The branch of biology that is generally concerned with the study of diseases is referred to as pathology. When such a study has to do with plants, it is known as plant pathology.
Mycology is the branch of biology that has to do with the study of fungi, phycology deals with the study of algae, while agronomy deals with the study of economically important crops.
Hence, the correct option is C.

Which of the molecules above is a tRNA molecule?
none of the above.
A
Ծ Ծ Ծ Ծ
C
B
Answer:
B
Explanation:
Transfer RNA (tRNA) is an RNA molecule involved in the process of translation by which cells synthesize proteins. These molecules (tRNAs) have 76-90 nucleotides in length which form characteristic stem-loop structures, and they are considered adaptor molecules because tRNAs serve as the physical link between the messenger RNA (mRNA) and specific amino acid residues of the growing polypeptide chain. A tRNA is composed of a trinucleotide region (i.e., the anticodon region) that binds to the codon in the mRNA, and a region that attaches to a specific amino acid in order to transfer it to the ribosome, where protein synthesis takes place.

Many plant pathologists believe that plant resistance is based upon the interplay of different signaling molecules? Justified.
Answer:
Yes.
Explanation:
Many plant pathologists believe that plant resistance is based upon the interplay of different signaling molecules because plants have various signaling molecules that plays a great role in their growth and development. Ethylene, auxin, cytokinins, gibberellins, and abscisic acid are the growth regulators that controls the growth of plants in different conditions i.e. in resistance. These signals leads the plant to take measures in difficult situations experience by the plants so in this way the plant is resistance to the harsh environmental condition.

Answer:
Explanation:
It is like expressing something
*K-selected
*r-selected
If a group of (. )
species lived together in a small area, the carrying capacity of that area would probably
collapse quickly.
Explanation: Unlike the r-selected species, the size of the population of K-selected species is fairly the same with time. The r-selected species generally lies below the carrying capacity, and the size of the population is density-independent. On the other hand, the K-selected species are generally at or close to the carrying capacity and the size of the population is density-dependent.

Explanation:
A)Exons 2 and 3 must have the same number of nucleotides. B)Exons 2 and 3 must contain an integral number of codons (that is, the number of nucleotides divided by 3 must be an integer). C)Exons 2 and 3 must contain a number of nucleotides that when divided by 3, leaves the same remainder (that is, 0, 1, or 2). D)Exons 2 and 3 must have different numbers of nucleotides. Multiple Choice
Answer:
Statement C is the only one that is necessarily true for exons 2 and 3. It is also true for exons 7 and 8. While statements A and B could be true, they don’thave to be. Because the protein sequence is the same in segments of the mRNA that correspond to exons 1 and 10, neither choice of alternative exons (2 versus 3, or 7 versus 8) can alter the reading frame. To maintain the normal reading frame—whatever that is—the alternative exons must have a number of nucleotides that when divided by 3 (the number of nucleotides in a codon) give the same remainder. Since the sequence of the a-tropomyosin gene is known, it is possible to check to see the actual state of affairs. Exons 2 and 3 both contain the same number of nucleotides, 126, which is divisible by 3 with no remainder.

D. Cytokinesis takes place, dividing the cytoplasm between the two daughter cells.
Determine which of the following statements is true about energy in ecosystems. A. Producers are able to convert 40% of the sun’s energy into chemical energy. B. 30% of the sun’s energy cannot be absorbed by producers because it is in the wrong wavelength of light. C. Producers only absorb 40% of the sun’s energy, most of which is lost during photosynthesis. D. Producers absorb 5% of the sun’s energy, and reflect 5% of the sun’s energy.
Answer:
A. Producers are able to convert 40% of the sun’s energy into chemical energy.
Explanation:
Energy in an ecosystem must be transferred in the ecosystem. The primary source of energy in an ecosystem is the sun. The terrestrial ecosystem mostly consists of plants and marine ecosystems. As energy flow in an ecosystem is unidirectional. It passed from the organism from one tropic level to another. Only 10% of the energy is available to them.Answer:

Both starch and cellulose are made by stringing together many glucose molecules, but starch is easily digested by humans, while cellulose is indigestible. The starch polysaccharide has every bond occurring below the sugar rings while the bonds in cellulose alternate between one bond above the ring and the next below the ring. How can you explain humans' inability to digest cellulose
Answer:
See explanation
Explanation:
The ability of humans to digest starch and cellulose depends largely on the presence or absence of enzymes that can hydrolyze the starch or cellulose linkages thereby making it digestible.
Starch can easily be digested but cellulose can not be easily be digested because human beings lack the necessary enzyme responsible for hydrolysing the beta-acetyl linkages in cellulose. As a result of this, humans do not metabolise cellulose.

What process occurs during transcription? (2 points)
Synthesis of proteins that are coded for by mRNA
Copying of DNA to form an mRNA strand
Replication of DNA to produce a complementary DNA strand
mRNA folding up by forming complementary bonds with itself
Answer:
Copying of DNA to form an mRNA strand
Explanation:
In transcription, DNA is copied to form an mRNA strand with complementary bases.
The DNA strand being copied during the process is called the template strand, and the mRNA that is made will be created from that strand.
This is the first step of protein synthesis.
This strand of mRNA is further used during translation, where it is used to code for amino acids to make proteins.
So, the correct answer is Copying of DNA to form an mRNA strand
Answer: The correct answer is Copying of DNA to form an mRNA strand
Explanation: Confirmed correct

In a well-fed human eating a Western diet, the richest source of stored chemical energy in the body is ________. In a well-fed human eating a Western diet, the richest source of stored chemical energy in the body is ________. glucose in the blood fat in tissue calcium phosphate in bone glycogen in muscle cells protein in muscle cells
Answer:
fat in tissue
Explanation:
Biomolecules like carbohydrates, fats etc. are well known for their energy storing abilities. Glucose, as a carbohydrate, is the most used source of energy but is stored in excess as glycogen in the muscle and liver cells.
However, fats are far more efficient in storing energy than carbohydrates or proteins because they give more ATP per molecule. Fats are stored in tissues of the body called ADIPOSE tissues. Hence, the richest source of stored chemical energy in the body is FATS IN TISSUES.
