Describe the two fields of study. Compares the genomes of different organisms compares the limbs of different organisms compares
maxonik [38]

It is assumed that organisms with similar anatomical characteristics have evolved relatively recently and have a common ancestor.

<h3>How does comparing the physical characteristics of different creatures help us understand evolution?</h3>

To comprehend how living things originated, scientists study the anatomy, embryos, and DNA of various species. Homological structures provide proof of evolution. These are features that were passed down from a common ancestor and are shared by related creatures. An further piece of evidence for evolution is offered by similar structures.

<h3>What role does anatomy play in the study of relationships between various types of organisms?</h3>

Comparative anatomy, which compares structural similarities, is one of the strongest types of evidence of creatures to ascertain the links between them throughout evolution. It is assumed that organisms with similar anatomical traits have evolved from ancestors who were reasonably closely connected to one another.

The human eye is most sensitive to green light of wavelength 505 nm. Experiments have found that when people are kept in a dark
Gnoma [55]

Answer: 9x10-3ms-1 -- A

Explanation:

Given wavelength λ = 505nm

1nm= 10^9m

505nm = 5.05 x10 ^-7m

and speed of light, c  is 3.8 x 10^ 8

frequency = ?

Using  frequency = speed of light / wavelength

f = c/λ

Frequency , f= 3.8 x10^8m/s/ 5.05 x10 ^-7m

=5.94 x 10 ^14 s⁻1

Also Energy = hv

where h =Planck constant  = 6.626 x10 ^ -34 J.s

v= frequency =5.94 x 10 ^14 s⁻1

 Energy = 6.636 x10 ^ -34 J.s x5.94 x 10 ^14 s⁻1

= 3.935 x 10 ^-19J

Given

9.5×10 −12 g as the mass of the bacterium,

changing to kg

1000g= 1kg

9.5×10 −12 g = 9.5×10 −15kg

to find the velocity

Energy = 1/2mv² = E=1/2mv²

v=\sqrt{2 xE/m}  =\sqrt{2 x 3.935 x 10^ -19 / 9.5 x 10^-15}

v =0.009099=   9x10-3ms-1

4. What is viscosity and how is it related to blood flow?
maria [59]

Increasing evidence supports the importance of hemodynamic forces that are directly related to the work of the heart as the primary triggering event of atherosclerosis and atherothrombosis. The factors that primarily determine the work of the heart include systolic blood pressure (BP), blood viscosity, and the volume of blood the myocardium has to pump.

The relationship between BP and viscosity is such that, given a constant systolic BP, if blood viscosity increases, then the total peripheral resistance (TPR) will necessarily increase, thereby reducing blood flow. Conversely, when viscosity decreases, blood flow and perfusion will increase. Because of the dependence of systemic arterial BP on cardiac output and TPR, if blood viscosity and TPR rise, systolic BP must then increase for cardiac output to be maintained. Consequently, blood viscosity has been established as a major determinant of the work of the heart and tissue perfusion [1]. Since increased viscosity requires a higher BP to ensure the same circulating volume of blood, both the burden on the heart and the forces acting on the vessel wall are directly modulated by changes in blood viscosity.

Three important studies helped establish the relationship between blood pressure and blood viscosity. The earliest study observed 49 normal subjects and 49 patients with untreated essential hypertension, showing a direct correlation between BP and blood viscosity among both normotensive and hypertensive subjects (p<0.001). Systolic blood viscosity was 8 to 10% higher in hypertensive patients compared with normotensive controls, and diastolic blood viscosity was 16 to 28% higher in hypertensive patients. Subgroups each comprised of 25 subjects having matched hematocrits were also compared, and viscosity remained significantly higher in hypertensive subjects (p<0.05). [2]
