Answer:  This answer is for all the questions: Chargaff's rules state that DNA from any species of any organism should have a 1:1 stoichiometric ratio of purine and pyrimidine bases (i.e., A+G=T+C) and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine.

What happens to the circulatory system when someone coughs?
natta225 [31]

Answer: The relationship between blood pressure and heart rate responses to coughing was investigated in 10 healthy subjects in three body positions and compared with the circulatory responses to commonly used autonomic function tests: forced breathing, standing up and the Valsalva manoeuvre. 2. We observed a concomitant intra-cough increase in supine heart rate and blood pressure and a sustained post-cough elevation of heart rate in the absence of arterial hypotension. These findings indicate that the sustained increase in heart rate in response to coughing is not caused by arterial hypotension and that these heart rate changes are not under arterial baroreflex control. 3. The maximal change in heart rate in response to coughing (28 +/- 8 beats/min) was comparable with the response to forced breathing (29 +/- 9 beats/min, P greater than 0.4), with a reasonable correlation (r = 0.67, P less than 0.05), and smaller than the change in response to standing up (41 +/- 9 beats/min, P less than 0.01) and to the Valsalva manoeuvre (39 +/- 13 beats/min, P less than 0.01). 4. Quantifying the initial heart rate response to coughing offers no advantage in measuring cardiac acceleratory capacity; standing up and the Valsalva manoeuvre are superior to coughing in evaluating arterial baroreflex cardiovascular function.

3. Si sales de tu casa y recorres 5 metros de distancia. ¿A qué distancia te<br><br> desplazaste?
olganol [36]

Answer:

5 metros.

Explicación:

Si sale de su casa y camina 5 metros, significa que está a 5 metros de su casa porque cubre 5 metros de distancia. La distancia es la longitud que recorre un cuerpo entre dos puntos. Aquí un punto es la casa y el otro punto es la persona, por lo que si calculamos la longitud, encontramos que el individuo cubre 5 metros por lo que podemos concluir que el individuo está a 5 metros de su casa si camina 5 metros de su casa. casa al exterior.

Describe the circumstances that cause a lunar eclipse to occur. What causes the moon to appear an orangish red during a total lu
Elodia [21]
A lunar eclipse happens when the Moon passes directly behind the Earth and into its shadow. This can only happen when the Sun, Earth, and Moon are aligned. Because of this, a lunar eclipse can only happen on the night of a full moon.

The moon gives off a reddish appearance during this time because the only light reaching the moon and reflected off of its surface is the light refracted by the Earth's atmosphere (the same reason a sunrise/sunset appears reddish).

A totally eclipsed full moon is also known as a Blood Moon because of it's colour
