What is the relationship between earth's temperature and the number of sunspots that occur?
o an increased number of sunspots causes an increase in earth's temperature.
o a decreased number of sunspots causes an increase in earth's temperature.
an increased number of sunspots causes earth's temperature to remain constant.
o. a decreased number of sunspots causes earth's temperature to remain constant.

The answer is: An increased number of sunspots causes Earth's temperature to remain constant.  O. A decreased number of sunspots causes Earth's temperature to remain constant.

Explanation:

In principle, sunscreens have no effect on the Earth's climate. They do not imply a drop in temperature on Earth, because there is no appreciable difference between the light emitted by the Sun when there are spots and when there are not. In fact, sunspots do not affect the Earth in any way.

The answer is: An increased number of sunspots causes Earth's temperature to remain constant.  O. A decreased number of sunspots causes Earth's temperature to remain constant.

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.  

during the process of dna replication, brdu can replace thymidine and incorporate into the newly synthesized dna, cell proliferation thus can be reflected in the extent of brdu incorporation.
