Which of the following provides the best example of how comparative embryology supports the theory of evolution?Humans do not lay eggs as birds do, but birds produce yolk sacs instead of embryos, suggesting birds evolved later than humans.
Humans have a tailbone that is not visible during embryonic development, which suggests that humans evolved to not depend on their tailbone serving a useful purpose.
Humans do not have gills as fish do, but human embryos have gill slits, suggesting humans and fish share a common evolutionary ancestor.

Which of following is not essential part of virus?

Answers

Envelope is not essential part of virus (option B)

What is virus?

A virus is a small, infectious agent that can replicate only inside the cells of living hosts. Viruses are not considered living organisms because they do not have their own metabolism or cell structure.

The essential parts of a virus are:

Nucleic acid: This is the genetic material of the virus, which can be either DNA or RNA. The nucleic acid carries the instructions for making new viruses.

Capsid: This is the protein coat that surrounds the nucleic acid. The capsid protects the nucleic acid and helps it to attach to host cells.

Mendel’s pea plants had either purple or white flowers. This means that the plants

Answers

Both purple and white flowers are recessive phenotypes. In order for an organism to exhibit a recessive phenotype, its genotype must be homogenous for the recessive allele. This is only possible if the parents of the organisms are also purebreeding and they demonstrate the same recessive phenotypes.

Maple trees are often tapped to extract the sap to make syrup. Which type of tissue is the aim of the tree tap? A) dermal
B) meristem
C) ground
D) vascular

Answers

D. Vascular tissue

Vascular tissue is known to be a complex conducting tissue that is formed by the arrangement of multiple cell types in vascular plants. Thus, the transportation of minerals, water and other products of photosynthesis occurred through the vascular tissue which is transported throughout the plant. However, both xylem and phloem are primary component of vascular tissue.

Answer: D. vascular

The maple trees are commonly tapped in order to extract its sap and make it into a syrup. The aim of the maple tree tap is the tissue of the tree known as the vascular tissue. These tissues resemble like pipes that transport fluids within the plant.

3.Original DNA Sequence: T A C A C C T T G G C G A C G A C TMutated DNA Sequence #5: T A C A C C T T G G G A C G A C T
What’s the mRNA sequence?
What will be the amino acid sequence?
Will there likely be effects?
What kind of mutation is this?

Answers

mRNA Sequence: AUGUGGAACCGUGACU

Amino Acid Sequence: Methionine-Tryptophan-Asparagine-Arginine-Cysteine.

Likely Effects: Minimal impact, as the mutation is a silent mutation, not changing the amino acid.

Mutation Type: Point Mutation.

To find the mRNA sequence, we need to perform transcription, where DNA is used as a template to synthesize complementary mRNA. In this case, we have a substitution mutation in the DNA sequence, so the mRNA sequence will also be affected.

Original DNA Sequence: T A C A C C T T G G C G A C G A C T

Mutated DNA Sequence #5: T A C A C C T T G G G A C G A C T

The mRNA sequence is formed by replacing T with U (uracil) in the DNA sequence:

Original mRNA Sequence: A U G U G G A A C C G C U G C U G A

Now, let's determine the amino acid sequence using the mRNA sequence. Amino acids are coded by codons (three-letter sequences). Here's the mRNA sequence grouped into codons:

AUG UGG AAC CGC UGC UGA

The codons code for specific amino acids:

AUG: Methionine (start codon)

UGG: Tryptophan

AAC: Asparagine

CGC: Arginine

UGC: Cysteine

UGA: Stop codon

So, the amino acid sequence is Methionine-Tryptophan-Asparagine-Arginine-Cysteine.

As for potential effects, the mutation seems to result in a single amino acid change (from glycine to asparagine). Whether this has significant effects on the protein's function depends on its role. If the protein is critical for an essential function, even a single amino acid change can have noticeable effects. However, if it's a less crucial protein or a non-coding region, the impact may be minimal.

This mutation is a point mutation, specifically a missense mutation, where one nucleotide is substituted with another, leading to an amino acid change in the resulting protein.
