The stem
1.is responsible for the transport of food and water from the roots and leaves to the other parts of the plant
2. The stem holds the plant upright or erect
3. It also stores the nutrients
4. It also produces new living tissues
Hope this helps!!!
There is a 1:4 chance of getting JjQq. The parent JjQq can produce four genotypes: JQ, Jq, jQ, and jq. the parent JJQq can produce two genotypes: JQ and Jq. When we do a punnett square:
JJQQ, JJQq, JjQQ, JjQq,
JJQq, JJqq, JjQq, and Jjqq
There are two JjQq.
Two out of eight is one out of four.
alpha cells are glucagon and beta cells are insulin
Answer: a) substrate and cofactors b) covalent modification
Explanation:
Metabolic pathways involve all the chemical processes takes place in the enviornment or in an organisms.The metabolic pathways are controlled through the catalytic activities of enzymes.
The availability of enzyme is regulated by substrate and cofactors present in enzyme and enzyme activity is commonly regulated via covalent modification.
Enzymes are highly selective in nature and bind to a specific substarte only. The active site in enzyme binds with the substrate to form enzyme substrate complex. Coactors assist the enzyme activity, without cofactor enzyme can not perform its activity.
Hence enzyme availibility is regulated by substrate and cofactors regulates.
Covalent modifications regulates activity of enzyme as it involves addition and removal of chemical group to synthesis required protein. It can change the chemical properties of the site by targeting one or multiple amino acid.
Thus the correct answer is a) substrate and cofactors b) covalent modification
Answer:
E. will have the same genes at the same locations
Explanation:
Homologous chromosomes are the pairs of chromosomes. The members of a homologous pair are genetically and morphologically similar to each other. One chromosome of a homologous pair is inherited from the father while the other one comes from the mother.
Genes have two or more alleles. The alleles of a gene occupy the corresponding position on the homologous chromosomes. These specific positions of alleles of a gene are called loci. Therefore, a particular locus is occupied by alleles of the same gene on two homologous chromosomes.
