Competition killed off all the organisms without traits that were benefitial to them. The organisms in the Galapogos Islands, such as the finches, made adaptions to settle in their new environment.

Answer:

It can be best explained with the help of Gause's law of competitive exclusion.

It states that no two species can coexist stably which compete for exact same resources.  

In such conditions, the species which is inferior to other in terms of adaptations either extinct or evolve towards a different ecological niche.

For example, Galapagos island finches evolved with different shapes and sizes of beaks as an adaptation towards limited resources available such as different types of seeds or food.

A species of mud snail was studied for five years. During this time, scientists observed the season in which they mated, the num
sergij07 [2.7K]

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.

In pea plants, the allele for inflated pod seed, I, is dominant over the allele for constricted pod seed, i. The Punnett square
zubka84 [21]

Answer:

<em>The offspring which carries the allele II will be homozygous dominant.</em>

Explanation:

A dominant trait can be described as a trait which masks the effect of a recessive trait. A recessive trait can be described as a trait which gets masked by the dominant trait.

A homozygous dominant trait occurs when both the alleles for the gen are dominant. A heterozygous dominant trait occurs when one allele is dominant and the other is recessive for the trait.  

Hence, a homozygous dominant trait will carry the alleles II.

mart [117]
During a 30 year period, the yearly frequency of drought is 10%, which is experienced in three separate years.
Additionally, drought is a period where precipitation is below average and thus resulting in prolonged shortages of water supply as far as both ground and surface water are concerned. This can last for several months or even for years.
