Explanation:
Some aphids make black walnut trees their habitat in the forest and only prefer to mate with aphids who have the same habitat. This is an example of reproductive isolation since these aphids now have different mating preferences and hence are isolated from rest of the aphids. The isolation occurred on the basis of difference in habitats so it is also an example of habitat isolation. Since the mating is prevented all together it is also an example of prezygotic barrier i.e. formation of zygote is inhibited. However, it is not an example of allopatric speciation since the aphids are not separated geographically from each other. They are present in the same area but have different habitat preference. Hence, option C is correct answer.
It consist of integral proteins and trans-membrane proteins and peripheral proteins as well
Answer:
The remaining ADP is at lower energy state.
Explanation:
ATP contain three phisphate bond. These phosphate groups form phosphodiester bond. Hydrolysis of each phosphate bond release about 7.3 Kcal of energy and one ADP. Now this ADP contain only one bond between phosphate group.
Result:
It is clered from the discussion that ADP is at lower energy level as compared to ATP due to less bond between phosphate group.
Basically, there is a presentation of types of food and the amount of those foods over 50 years in this graph. This means the graph is showing amounts of certain foods over the time period. I'm guessing that basing off of the the previous text you're just noting a change in the breaks of birds based off of the diet available to them at certain times. The adaptations and natural selection will explain the changes because due to certain limited and available foods the diet of the birds change.
Answer:
The muscular system is the set of more than 650 muscles in the body, whose main function is to generate movement, whether voluntary or involuntary.
Explanation:
The functioning of the muscular system can be divided into 3 processes, one voluntary in charge of the skeletal muscles, the other involuntary carried out by the visceral muscles and the last process is the duty of the cardiac muscles and autonomous functioning.
Skeletal muscles allow walking, running, jumping, in short, they empower a multitude of voluntary activities. Except for reflexes, which are the involuntary responses generated as a result of a stimulus. As for involuntary functioning muscles, it can be specified that they perform independently of our will but are supervised and controlled by the nervous system, they are responsible for generating pressure for the transfer of fluids and the transport of substances throughout the organism with the help of peristaltic movements (such as food, during the digestion and excretion process).
The autonomous process takes place in the heart, an organ made of heart muscles. The primary function of this muscle tissue is to contract regularly, millions of times, having to endure fatigue and weariness, or else the heart would stop.
