Frank father has skin without sweat glands. where his mother has normal skin.So his father is also affected with a disorder and supposed to be mutant. Frank would have received the mutant chromosome from his father.
Nondisjunction would have occurred at meiosis I. Because, the chromosomes separate(and not chromatids) at that stage.while separation, both XY chromosomes would have gone into a single cell.So during meiosis II when sperm with XY chromosome fuses with Egg with X chromosome the daughter cell would have an XXY genotype which is klinefelter syndrome.
Answer:
3.) The giraffe has adapted by it's neck length increasing to reach the branches
4.) Biotic factors
Explanation:
<u>QUESTION 3:</u> Due to the leaves growing towards the top of tree rather than around, the giraffes neck length impacts the access to the leaves, so they have adapted by increasing their neck length.
<u>QUESTION 4:</u> Giraffes and trees are both living things, therefore they are biotic factors.
According to the Kübler-Ross grief model, the stage following denial is anger.
In biochemistry, enzymes are protein catalysts of the body that speeds up certain specific metabolic reactions in the body. They word in the concept of lock-and-key theory or induced fitting. These two theories are all based on the shape and size of the enzyme's active site that could accommodate the substrate. So, the main function of the enzyme is dependent on its shape. Therefore, when an enzyme undergoes denaturation, its orientation and shape changes. For example, a beta pleated sheet may change to an alpha helix orientation. As a consequence, the number and capacity of active sites changes. Hence, the enzyme becomes nonfunctional.
Answer:
A). True
Explanation:
tRNA, which means transfer RNA is one of the three types of RNA known in nature. The tRNA is found in the ribosome, where it plays a pivotal role in protein synthesis (translation). Transfer RNA is the RNA responsible for reading the nucleotides in the mRNA codon and carrying the amino acid that corresponds those codons to the ribosome.
The tRNA has a 3-dimensional structure that allows it to carry anticodon that reads codon and also carry amino acids on opposite ends. Hence, according to this question, tRNA is a type of RNA that delivers amino acids to the ribosome during protein synthesis.
