What your cells have to help overcome a problem of high activation energy are called enzymes. Enzymes are proteins that lower the activation energy of a reaction. In doing this, enzymes increase the rate of a reaction, helping it to occur faster. However, enzymes are not consumed in a reaction; they simply help it to occur.
Enzymes make things easier for your cells to work properly and help chemical reactions occur. There are hundreds of different kinds of enzymes in your cells, which all participate in different types of reactions. Enzymes can break molecules apart, build or add molecules, and even rearrange them.
In lowering the activation energy of a reaction, enzymes decrease the barrier to starting a reaction. It's important to note, however, that the change in energy remains the same between the start and end of a chemical reaction.
It is a form of natural selection called sexual selection.
Answer:
The major characteristic feature of asexual reproduction is the production of clones.Identical offspring with virtually similar DNA.Therefore,this is advantageous to the parasite because, the offspring or progeny produce are similar(clones), to the parent parasites,thus multiple reproduction can occur when a single individual parasites cells divisions.
Explanation:
Answer:
Petiole
Explanation:
The petiole is the part of the leaf that attaches the leaf to the main stem of the plant. Depending on the leaf structure of the plant, some leaves may be devoid of a petiole, and be regarded as apetiolate.
The correct answer is: about 99%.
The main difference between two random people’s genetic make-up issingle base pair differences, or polymorphisms (SNPs). There are about one SNP per 1000 bases. Since the human genome is about 3 Gbp long, about 3 million SNPs among two random people is present. SNPs may occur within coding sequences of genes, non-coding regions of genes, or in the intergenic regions.
