The correct answer is option B. The scientists were studying if the mud snails can reproduce both sexually and asexually. The characteristics in the study included parameters such as the mating season, number of offspring, effect of environmental stress conditions and lack of mates. Out of all the parameters being studied can affect asexual reproduction in the mud snail but lack or presence of mates is a parameter required to be studied to determine the mode of reproduction i.e. sexual or asexual because need for mates or mate dependent reproduction occurs in case of sexual reproduction.
Answer:
A particular population limiting factor or factors must have been removed
Explanation:
The population of the birds must have been kept between 30 and 50 individuals by population limiting factors such as the presence of predators within the community or competition for resources such as food or spaces.
For the population to shoot up to 90 all of a sudden, it may be that one or more of the population limiting factors has been removed from the population. <u>It could be that a major predator has been removed from the community or the competition for food/space is now significantly reduced due to more food/space in the community. </u>
Answer: This mode of inheritance is known as Incomplete Dominance
Explanation:
Incomplete dominance occurs when a cross between two contrasting alleles (such as Type A and B) produces a heterozygous phenotype different from the two parents.
Thus, both Type A and B are dominant over Type O blood
Answer:
Muscle cramps are caused by the inability of myosin fibers to break free from the actin filaments during contraction, resulting in a prolonged contraction. A lack of ATP would obviously produce cramping, as myosin requires ATP to become free from actin.
