Peroxisomes are tiny vesicular cell organelles that contain powerful digestive enzymes to break down lipids and certain toxins.
Therefore, there would be more Peroxisomes in the cells that form the tissue involved in digesting lipids, such as stomach and intestine.
It is called stimulus, it triggers a response in biological system and leads to either negative feedback (more common) or at time positive feedback (relatively less frequent).
Two individual trying to use the same resource are in fact competing to use that resource for their survival. sustenance or propagation. The phenomenon is known as competition, a force that drives evolution where favorable trait is supported for propagation in the population. Individual that lack...
Energy is only transferred from one form to another.
Exercise through physical activity will convert potential energy into kinetic energy of motion or hear energy.
Yes, potential energy is being spent but it is also transferred into kinetic or heat energy...
Plants are alive but they only move partially, the thinner branches move with strong wind/storm etc.
The statement is false.
Glucose provides energy when it is being broken down.
Some tissues need more energy than others.
In such tissues with higher energy demand, energy powerhouse (mitochondria) generate energy for biological work.
Therefore, tissues with relatively...
What a a brick is to city, a cell could be the same to body!
Can you write the comparison using appropriate examples from the body and the city?
Daughter cell of mitosis have the same number of chromosomes as mother/parent cell and has same genotype, there is no recombination in mitosis and therefore, cellular genotype and phenotype of daughter cell would be 100% replica of mother/parent cell.
It is China, due to its wide variety of rice strains and very high percentage of rice eating population.
Explanation through diagram/figure and its legend would be the best but unfortunately, this platform does not allow a detailed diagram. If you can send one to me by email then I shall be happy to comment and help.

Since it was parthenogenetic development, a zygote developed from one egg where Chromosomes of haploid egg were duplicated during replication cycle producing homozygous parthenogenetic baby snakes. Whichever allele was in the haploid egg, that created its homologue leading to homozygous individual...
Yes, that is true for diploid somatic cells, germ cells (eggs and sperms) are haploid and therefore, they have half the number of chromosomes. Germ cells might carry recessive mutation instead of wild-type allele or other way around. They would only carry one allele and not both alleles.
If DNA molecule has 32% G (guanine) then it would have the same % of C (Cytidine) since G pairs with C in a double stranded DNA molecule, that would be the same during semi conservative replication.
Rest of it would be divided in A (adenine)...
Here it is:
1. DNA is used as a template to create mRNA
2. mRNA molecule binds to a ribosome
3. tRNA binds to the ribosome (specific tRNAs bring individual amino acids reading mRNA codons)
4. Amino acids are bonded together...
By definition, negative feedback is where the final response to initial stimulus counteracts that stimulus. I illustrate it below:
Stimulus A→Response→Stimulus B→
↑←← ←←←←← ←←←←← ←←←←←↓
Stimulus A is creating a response...
Gene expression implies expression of protein encoded by the gene. Some gene express constitutively while others express at certain time and place, such expression is known as temporal and spatial gene expression. These second category of gene remain in repressed state and therefore, they need to...
Please check the question again, it should be
What enzyme/s unwinds the DNA and begins to make new mRNA strand?
Such question makes sense rather than "undefined"
mRNA is synthesized by RNA polymerase but DNA needs...
If you find a dwarf pea plant with heterozygous genotype tT, then you would have to conclude that there is new point mutation that disrupts the functional dominance of T allele and now it is unable to dominate recessive t allele. Instead, it is behaving like a recessive t allele. You need to check...
Gradual glucose oxidation releases ATP, the energy currency of biological systems. Cells can only store small amount of ATP and therefore, gradual oxidation provides with energy supply for a relatively longer duration releasing only small amount of ATP at a time. That gets utilized for biological...
Vacuoles will usually store an infected or toxic particle until the lysosomes destroy it. They do not synthesize anything nor do they release energy.
