What is an amniotic egg?
Answer: The amniotic egg was an evolutionary invention that allowed the first reptiles to colonize dry land more than 300 million years ago. Fishes and amphibians must lay their eggs in water and therefore cannot live far from water. ... Within the chorion is the amnion, the membrane for which the amniotic egg is named.

Which one of the following statements is wrong with respect to separation of DNA fragments on gel electrophoresis?
4 points
a. Gel electrophoresis is employed to check the progression of a restriction enzyme digestion.
b. The DNA fragments move towards cathode under electric field through the matrix.
c. The smaller DNA fragments moves farther.
d. The commonly used matrix is agarose gel.
Answer:
b. The DNA fragments move towards cathode under electric field through the matrix.
Explanation:
Gel electrophoresis is a molecular biology technique used to separate DNA fragments based on size using electric current. The electric current passes through a GEL (agarose gel is commonly used) matrix. Due to the fact that DNA is negatively charged, they tend to move towards a positively charged electrode called ANODE.
However, the smaller the size of the DNA fragment, the faster and farther it moves along the matrix. Gel electrophoresis is indeed a technique used to check how progressive a restriction enzyme has been able to digest DNA molecule into fragments.
Glucose is a large molecule that is transported across the cell
membrane through a gated channel, a type of transport protein
used during what
diffusion
The type of transport protein used during glucose transportion across the cell membrane is facilitated diffusion.
Glucose is the main energetic substrate of the cell and requires a transporter protein in the cell membrane for its entry.
Proteins found on the surface of the membrane intervene in facilitated diffusion, which, when they make contact with the molecules, bind to them and allow their entry.
This route is used by molecules that are larger in size, with properties other than the membrane (polar), or are charged and do not cross the membrane freely; for example glucose.
The transport of glucose across the cell membrane is carried out by two families of membrane proteins:
Sodium-coupled glucose transporters are expressed mainly in epithelia that are responsible for the absorption and reabsorption of nutrients.Glucose transporter (GLUT) are expressed in all cells of the body and allow glucose to move from one compartment to another.
Therefore, we can conclude that glucose enters cells through facilitating transport systems, glucose transporter are expressed in all tissues of the organism and transport glucose through its concentration gradient, hence the name of facilitated diffusion.

what's wrong in asking these types to Question.. it's based on studies
Answer:
sporopollenin
While the exine is composed of sporopollenin, a complex and highly resistant biopolymer containing fatty acids, phenylpropanoids, phenolics and carotenoids, the intine is largely composed of pectin and cellulose.
Explanation:
The climate changes on Earth tend to be self-amplified. For example, the Earth is
currently going through a warming trend. As the Earth's temperature rises, the ice caps
and sea ice melt, reflecting less solar radiation. This results in more absorption of the
Sun's heat, causing the Earth's temperature to rise more, and the ice to melt more. This is
an example of what type of system?
Answer:
negative feedback
Explanation:
This is an example of negative feedback system.
What do you mean by negative feeback?Negative feedback occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances.
Negative feedback (or balancing feedback) occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances.
A negative feedback is a self-regulatory system in which it feeds back to the input a part of a system's output so as to reverse the direction of change of the output.

True or False
Answer:
true
hope this helps you ☺️☺️
Electron transport chain can be defined as the series of organic molecules and proteins which are embedded in the inner membrane of mitochondria. These molecules are involved in the shutting of electrons from FADH2 and NADH to the [tex]O_{2}[/tex].
The molecular oxygen is the final electron acceptor in this electron transport chain that leads to the formation of water and ATP as the end products. This chain takes place in the mitochondria in both animal and plant cells.
Hence, the given statement is true.

The ADG1(ADP glucose pyrophosphorylase 1) is involved in flowering timing in plants. You are interested in developing a DNA probe using partial protein sequence information. Part of the amino acid sequence is Glu-Glu-His-Asp-Val-Leu 1. determine the possible antisense oligo nucleotides possible from this amino acid sequence 2. How many total unique different oligonucleotide would need to be produced to cover all possibilities
Answer:
1) UUC-AUG-AUC-AAG-UAA.
2) 48
Explanation:
1) Determine the possible antisense oligo nucleotides possible from this amino acid sequence
Given that the peptide sequence is = Glu-Glu-His-Asp-Val-Leu 1.
we will use a codon table to show the codons and Anticodons for each of the Amino acids
Amino Acid Codons Anticodons
Glu GAA, GAG UUC, CUC
His CAU, CAC AUG, GUG
Asp GAU, GAC AUC, GUC
Val GUU, GUC, GUA, GUG AAG, GAC, UAC,CAC
Leu UUA, UUG, CUU, CUC, CUA, CUG | UAA, CAA, AAG, GAG,UAG,CAG
From the table above
The possible antisense oligo nucleotide sequence is : UUC-AUG-AUC-AAG-UAA.
2) How many total unique different oligonucleotide would need to be produced to cover all possibilities
A desired peptide sequence requires 16 anticodons
Hence the total unique different oligonucleotide needed to be produced to cover all possibilities = 16 *3 = 48
The ADG1(ADP glucose pyrophosphorylase is involved in flowering timing in plants and a DNA probe is made by using partial protein sequence information. Part of the amino acid sequence is Glu-Glu-His-Asp-Val-Leu.
1. To determine the possible antisense oligonucleotides possible from this amino acid sequence:
Since, for every amino acid, there is a specific codon and anticodons are present so according to the given information, the possible antisense oligonucleotides for Glu-Glu-His-Asp-Val-Leu is UUC-AUG-AUC-AAG-UAA.
2) The total number of unique different oligonucleotides that would need to be produced to cover all possibilities is 48
since the amino acid sequence is Glu-Glu-His-Asp-Val-Leu has 16 anticodons and each anticodon have 3 nucleotides so the possible number of oligonucleotides are :
16×3 = 48.
What are codon and anticodon?A codon is a trinucleotide sequence of RNA that corresponds to a specific amino acid.
An anticodon is a trinucleotide sequence complementary to that of a corresponding codon in a messenger RNA sequence.
Thus, according to codon and anticodon, the possible antisense oligonucleotides for Glu-Glu-His-Asp-Val-Leu is UUC-AUG-AUC-AAG-UAA and a number of unique different oligonucleotides that would need to be produced to cover all possibilities is 48.
