Answer:
D
Explanation:
This is because one of its orbital shells is not filled – the one with 1 electron. This atom will, therefore, want to lose this electron – it takes less energy to do this than gain 7 electrons -- to achieve stable electron configuration. This makes this atom very reactive in a chemical reaction. Usually orbital shells of atoms begin with an S orbital shell that is filled with 2 electrons then P (x,y,z) orbital shells filled with 6 electrons total. There are also higher energy f and d orbitals that each take a maximum 10 and 14 electrons respectively. An atom is stable if its orbitals are fully filled.
Answer:
C. All fossils contain intact DNA that can be sequenced.
Explanation:
Fossils are the impression, trace or preserved remains of once-living thing from past thousands of years such as bones, exoskeletons, objects preserved in amber, and stone imprints of animals or microbes.
Fossils provide evidence about seevral characteristics and features of extinct organism such as evolutionary relationship between organisms and transitional forms between groups of organisms. but all the fossil do not provide evidence about the intact DNA that can be sequenced because some fossils carry DNA rumnants which do not have the ability to get sequenced.
Hence, the correct option is C.
The best and most acurate answer for this is definatlly b
due to d dealing with speed
c is loss of vision
and a is something to do with how we see things that go on for a while in art like a hallway falling into a single point like in art<span />
The ability of a person's cardiovascular system to compensate for blood loss is most related to how rapidly he or she bleeds.
<h3>
what is cardiovascular system made up of?</h3>
Your cardiovascular system, which consists of your heart and blood arteries, is an essential component of your body. When your cardiovascular system is functioning properly, your cells receive a constant supply of oxygen and nutrients from your blood. Carbon dioxide and other waste are also removed via blood vessels. You have the ability to maintain your heart and blood vessels healthy. Eating healthy foods, exercising, keeping your blood pressure and cholesterol under control, and quitting smoking are all beneficial to your cardiovascular system. Request assistance from your provider in achieving heart health.
