Name two ways that veins and arteries are different.
kakasveta [241]
The chief difference between arteries<span> and </span>veins<span> is the job that they do. </span>Arteries<span> carry oxygenated blood away from the heart to the body, and </span>veins<span> carry oxygen-poor blood back from the body to the heart. 

Another difference would be v</span><span>eins have valves and arteries do not. In arteries, blood flows in the right direction because of the heart pumping it forwards at high pressures. The lower blood pressure in veins means that valves are needed to stop blood flowing backwards (for example, in veins in the legs, blood needs to flow upwards against the pull of gravity).</span>

Describing the experience of a snowflake melting on one's tongue as "cold . . . Wet . . . Tingly . . . Slightly metallic in tast
makkiz [27]

Answer;

Wundt; introspection

Describing the experience of a snowflake melting on one's tongue as "cold . . . Wet . . . Tingly . . . Slightly metallic in taste" echoes Wundt's method of introspection.

Explanation;

The pioneering psychologist Wilhelm Wundt used a method called introspection to enable subjects to examine their own mental processes. introspection is used to describe a research technique that was first developed by psychologist Wilhelm Wundt.

Introspection is the examination of one's own conscious thoughts and feelings. In psychology, the process of introspection relies exclusively on observation of one's mental state, while in a spiritual context it may refer to the examination of one's soul.

Given the following DNA template, what is the appropriate mRNA strand <br> 3' TACTTCAAACCGATT 5'
xeze [42]

Answer:

5' AUGAAGUUUGGCUAA 3'

Explanation:

The process by which the information encoded in a DNA is used as a template to synthesize a mRNA is called TRANSCRIPTION. It is the first stage of gene expression carried out in the nucleus of eukaryotic cells and cytoplasm of prokaryotic cells by RNA polymerase enzyme.

The process of transcription follows the complementary base pairing rule, which says that Adenine base always hydrogen pairs with Thymine while Guanine pairs with Cytosine. During transcription, the Thymine base (T) is replaced by Uracil base (U). Hence, whenever RNA polymerase reads an A in the DNA, it synthesizes U in the mRNA and vice versa for T and A. The same applies for G and C.

For the DNA sequence;

3' TACTTCAAACCGATT 5'

The mRNA sequence will be synthesized;

5' AUGAAGUUUGGCUAA 3'
