Answer:
pH - Each enzyme has an optimal pH at which it works best, if the pH is too acidic or basic, the enzyme will start to denature.
Temperature - Each enzyme has an optimal temperature at which it works best as well. If it is too hot, the enzyme will start to denature and if it is too cold, there will be fewer collisions between enzymes and substrates.
Explanation:
There are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells.
Mitosis is a fundamental process for life. During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells. Because this process is so critical, the steps of mitosis are carefully controlled by a number of genes. When mitosis is not regulated correctly, health problems such as cancer can result.
The other type of cell division, meiosis, ensures that humans have the same number of chromosomes in each generation. It is a two-step process that reduces the chromosome number by half—from 46 to 23—to form sperm and egg cells. When the sperm and egg cells unite at conception, each contributes 23 chromosomes so the resulting embryo will have the usual 46. Meiosis also allows genetic variation through a process of DNA shuffling while the cells are dividing.
Bleaching of the coral reefs. This is caused from greenhouse gases in the atmosphere, a main cause for these gases are our vehicles we drive.
Answer:
The genetic information in DNA is carried to the cytoplasmic protein-manufacturing centers in form of mRNA.
Explanation:
The process of transcription forms RNA using the DNA template strand thereby copying the genetic information of DNA into the nucleotide sequence of mRNA.
The mRNA leaves the nucleus and enters the cytoplasm to join ribosomes. The nucleotide sequence of mRNA is read in the form of triplet codons to specify the amino acid sequence of the proteins.
In this way, mRNA serves as a carrier of the genetic information in DNA.
Answer:
B)They are capable of Photosynthesis
Explanation:
Euglenas are heterotrophic and autotrophic, so they consume food and make their own through photosynthesis. Therefore, they are photosynthetic.
