Question is incomplete i have added full question in ask for detail section as well as in picture format with answer. See figure for clear explanation.
Answer:
(Twisted leaves)
The mutant allele is dominant to its corresponding wild-type allele
(Forked leaves)
The mutant allele is dominant to its corresponding wild-type allele
(pale leaves)
The mutant allele is neither dominant nor completely recessive to its corresponding wild-type allele
Explanation:
I have attached picture which explains phenomenon it self.
The correct answer is co-adaptation.
Co-adaptation in biology refers to the procedure by which two or more species, phenotypic traits or genes go through adaptation as a group or pair. This takes place when two or more associating features go through natural selection together in response to the similar selective pressure or when selective pressures change one feature and simultaneously changes the interactive feature. These associating features are only beneficial when together, in certain cases resulting in increased interdependence.
Chemical reactions that take place inside living things are called biochemical reactions. The sum of all the biochemical reactions in an organism is called metabolism.Metabolism includes both exothermic (energy-releasing) chemical reactions and endothermic (energy-absorbing) chemical reactions.
Answer:
The correct answer would be "T-lymphocytes would bind self-antigens".
Negative selection of T-lymphocytes takes place in the cortico-medullary junction in the thymus.
It removes T-lymphocytes which show high-affinity binding with self-antigen. Thus, it helps in introducing self-tolerance in T-lymphocytes.
In absence of negative selection, T-lymphocytes which show high-affinity binding for self-antigen would survive and develop into mature T-lymphocytes.
Consequently, T-lymphocytes would able to bind to self-antigens of the body which can result in autoimmune disease.
Answer:
True.
Explanation:
Trees are responsible for stabilizing carbondioxide concentration in the environment because carbondioxide is used by the plants in the process of photosynthesis. So when we cut down trees, the carbon which is present inside the body of plants also emitted in the form of carbondioxide by the process of decomposition. Decomposers such as bacteria and fungi etc are responsible for the release of carbondioxide.
