What are the Amino acids of the mutated DNA sequence: TAC ATC TTG GCG ACG ACT
Answer:
Tyr Ile Leu Ala Thr Thr
Explanation:
In a DNA sequence, a pair of three bases form a codon that codes one particular amino acid in the protein. Proteins are consist of 20 amino acids and these amino acids are coded by a pair of three bases.
There are four bases in a DNA - Thymine (T), Adenine(A), Guanine(G) and Cytosine(C).
The given mutated DNA sequence will also code for some amino acid, that is as follows:
TAC - Tyr (Tyrosine)
ATC - Ile (Isoleucine)
TTG - Leu (Leucine)
GCG - Ala (Alanine)
ACG - Thr (Threonine)
ACT - Thr (Threonine)
Thus, The mutated DNA sequence TAC ATC TTG GCG ACG ACT codes for Tyr Ile Leu Ala Thr Thr.
What is the main cause of pollution
Answer:
Humans
Explanation:
The main cause of pollution is the burning of fuel, over-use of fertilizers and pesticides, carelessness, and the improper disposal of waste. And who does this? Not casper, not pennywise, not animals, but us humans. So we are the main reasons why pollution exist.

I
Genotypes of offspring:
Phenotypes of offspring:
Plz help me
Answer:
Crossing two chickens heterozygous for the trait feather color, when brown feathers are dominant over red feathers, will produce offspring with brown and red feathers in a brown:red phenotypic ratio of 3:1.
Explanation:
Knowing that in chickens brown feathers are the expression of the dominant allele (B) and the recessive allele is red (b), crossing two heterozygous individuals (Bb) will result in offspring that are likely to have brown or red feathers.
The cross can be represented by a Punnett Square:
Bb X Bb cross
alleles B b
B BB Bb
b Bb bb
Where the result is:
Genotypes:
Bb, 50% BB, 25% bb, 25%Phenotypes:
Brown feathers, 75% Red feathers, 25%.In this case, the probability of having brown or red feathers is 3:1.

Which of the following best describes the genetic complement in each
daughter cell at the conclusion of meiosis?
A. A haploid set of chromosomes that are a recombination of the
parents' chromosomes
B. A diploid set of chromosomes that are identical to the parents'
chromosomes
C. A diploid set of chromosomes identical to the other daughter cells'
chromosomes
D. A haploid set of chromosomes that are identical to the parents'
chromosomes
Answer:
A
Explanation:
Meiosis end in four daughter cells that are haploid and contain half the chromosomes as the parent cell and genetically different from the parent cell and from each other, so A would be the right answer.
A haploid set of chromosomes that are a recombination of the parents' chromosomes best describes the genetic complement in each daughter cell at the conclusion of meiosis.
What do you mean by meiosis?Meiosis is a special type of cell division of germ cells in sexually-reproducing organisms that produces the gametes, such as sperm or egg cells.
Moreover, meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells.
Meiosis is important for three main reasons: it allows sexual reproduction of diploid organisms, it enables genetic diversity, and it aids the repair of genetic defects.

Pisces or Class Fish is the largest group of chordates which includes 25000 species of fishes. Study of fishes is called Ichthyology.
Fish is an aquatic gill breathing gnathostomates whose stramlined body is provided with paired fins and covered over dermal scales.
Super Class pisces is divided into two classes:
Chondrichthyes Osteichthyes _____________________________________
[tex]\Huge\textbf{Chondrichthyes}[/tex]
Chondrichthyes are Cartilagineous fishes. This class is also called Elasmobronchi. It has exclusively marine fishes with endoskeleton made of cartilage. Their skin has tiny shark enamel coated denticles called Placoid Scales. They are heterocercal and Mouth is present at ventral to tail fins. They have exposed 5 gills on each sides.
Example Shark, Ray fishes, Dog dish etc
_____________________________________[tex]\Huge\textbf{Osteichthyes}[/tex]
These fishes are Bony Fishes. This group is also called Teleostomi, They are found in both marine and fresh water. Their endoskeleton is made up of bones. Their skin has thin bony plates called cycloid or ctenoid. Their gills are covered with outer skin called operculum. Tain fin is homocercal and mouth is present at anterior tip.

Answer: Sensory Neurone and a synapse
[tex]\Huge\text{1) Sensory Neurons}\\\\\Huge\text{2) Synapse}[/tex]
_____________________________________[tex]\Huge\textbf{Reflex Action:}[/tex]Reflex action is a involuntary and instantaneous action in response to a stimulus acting over a reflex arc. Some reflex actions are inherited and innate while other are acquired through learning processes. These reflex actions are performed without the will of the animal & generally involve minimum number of neurons.
Reflex Arc:Many neurons work in group called reflex arc, There must be atleast two neurons in a reflex arc. A reflex arc is made possibly a shortest pathway so the body acts on an impulse before it reaches the brain, and usually it is coordinated by spinal cord and brain-stem.
The parts of reflex arc is given as,
A receptor, a sense organ in the skin muscle or other organ.An afferent or sensory neuron, which carries impulses towards the central nervous system.The central nervous system, where a synaptic connections are made between the sensory neuron and the inter-neurons.The efferent or motor neurons which makes a synaptic connection with the inter neuron and carries impulses out from the central nervous system.The effector, by which the animal responds to the environmental changes.The change in the body is detected by receptors which gives the information to the brain or spinal cord which is the control center via the sensory neuron. The control center decides the appropriate response and sends it to the effector via motor neuron which plays its role.
_____________________________________[tex]\Large\textbf{Synapse:}[/tex]
a synapse is a small gap at the end of a neuron that allows a signal to pass from one neuron to the next. Synapses are found where nerve cells connect with other nerve cells or the muscle.

Determine the parents genotype
A) BBSS
B) BBss
C) BbSs
D) BbSS
Answer:
C. BbSs
Explanation:
The foiled results of the genotype include both capital and lowercase versions of both letters, b and s.
This means the genotype has to be heterozygous for both the B and S traits, since the foiled results have both dominant and recessive alleles.
So, the genotype must be C, BbSs
The foiled results of the genotype for the offsprings include BS | Bs | bS | bs.
The parent's genotype will then be BbSs.
The genotype of both parents have to be heterozygous as a result of the
presence of its forms in the B and S traits. There is the presence of the
dominant (B,S) and recessive traits (bs).
The genotypes of the parent will however have both traits in them which
translates to the option C) BbSs being the most appropriate.
