Answer:
First law of thermodynamics is the conservation of energy states that energy is not created and not destroyed but only can be stored.
Thermodynamics second law states that total entropy of a system increases from lower to higher system and some of the energy is always wasted during the work done.
In the food chain plants are the producers which accept light energy and stored in the form of chemical energy and energy flow to the herbivores and higher trophic levels in the chemical form only and no new energy is created in between the chain (Fisrt law of thermodynamics). Heat is generated during respiration by plants and animals (wasted energy) and entropy also increases with the increase in level of the pyramid of energy (Second law of thermodynamics).
Answer:
One-half of the daughters of an affected man would have this condition.
Explanation:
Each daughter born to a woman that is positive for a dystrophin mutation on one of her two X chromosomes possess a 50 percent likelihood of possessing the mutation and also becoming a carrier. Carriers at times do not show the disease symptoms but may give birth to a child that has the mutation or the disease condition. DMD carriers do have a higher chance of cardiomyopathy.
A man with DMD cannot transfer the affected gene to his sons since he passes to his son a Y chromosome, not the X chromosome. But he will definately transfer it to his daughters, since each daughter possess her father’s only X chromosome resulting in the daughters being carriers.
Hence, One-half of the daughters of an affected father and a carrier mother could have this condition.
The correct answer is B. Contact comfort
Explanation:
Studies with Rhesus monkeys were carried out by the psychologists Harry Harlow to study psychological and emotional aspects related to maternal separation and isolation. In this experiment, Harlow used baby monkeys and observed their behavior in different situations that included separating the baby and the mother, providing a fake mother, isolating baby monkeys for a long time and allowing baby monkeys to choose between their mother or food. The results of this experiment showed mother-infant emotional bonds were key for the development and socialization of monkeys, this could be explained as mother monkeys provided contact comfort which supported a positive development and prevailed over food or nourishment.
