Which change would occur over the longest amount of time? a. tide rising b. high pressure system forming c. wind direction changing d. polar ice caps melting

Option (D)

Explanation:

The polar ice cap melting is an event that takes place at a longer duration, and is usually measured by the end of every decade. This melting of ice caps in the polar region is caused due to the increasing amount of the earth's surface temperature. One of the main reasons is the increasing amount of carbon in the atmosphere for the last few decades.

On, the other hand, there occurs certain changes which take place in a very short time, in terms of hours or days. Some of its examples include the rise in the sea level due to the tidal effect, changing of wind direction and changing of the pressure system from low to high and vice versa.

Thus, the correct answer is option (D).

not the best question format lol but what i think might as scale color is controlled by a single gene with two alleles, the green allele and the yellow allele. when moths that are homozygous for green scales are mated with moths that are homozygous for yellow scales, 100% of the offspring have green scales.

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.
