Answer:
Molecular chaperons in the cells helps in protein folding. These are the group of proteins that have functional similarity and they also assist protein folding.
They have the ability to prevent the non specific binding and aggregation by the binding of the non native proteins.
Molecular chaperons helps in recognizing the hydrophobic surfaces of the unfolded proteins because they themselves are hydrophobic in nature and will combine to the hydrophic binding and bonding.
This helps in guiding the protein to folding.
Binary fission is the process of a bacterial cell going from singular to double. Therefore the correct answer would be: "During binary fission, a bacteria cell grows in size because DNA and other organelles are duplicated."
Variations can be genetic or environmental, the traits are passed from one generation to other generation of snail is from from both parents to offspring and through the environment.
The correct answer is C.
Explanation:
Genetic variation in an organism is passed to the offspring by its parents.
environmental variation is the the result of different environment with which individual adapt.
Natural selection is a process in which a suitable trait which is well adapted to the environment is passed on tho future generations.
Genetic variation is the change in DNA or gene of the individual trait. The tree snails having different pattern in their shells is due to the habitat they are living in.
The snails which have well adapted to the environment are able to reproduce and pass on the traits to their progeny. The variation is due to the traits passed from parents through the environment also.
Blood carries immune system cells, known as white cells or leukocytes. Some examples of white cells are phagocytes and lymphocytes.
Phagocytes ingest and dissolve pathogens, as well as strange particles or dying cells.
Lymphocytes are divided into T cells, B cells, and natural killer cells (NK). B cells produce antibodies to respond to foreign cells, T cells attack pathogens using enzymes and other non-antibodies responses, while NK cells combat tumors and cells infected by viruses.
A. A gamete carries to genes for a trait.
B. A gamete carries one allele for a gene.
C. A gamete can carry multiple alleles for a trait.
D. Some gametes are dominant and some are recessive.
