Answer:B.quadrupedalism

Explanation:

Studies today proves that bipedal locomotion evolved from quadrupedalism because it was more energy efficient.

In a research conducted by scientists

4 humans and 4 chimpanzees were made to run on a treadmill, the chimpanzees were trained to walk quadrupedally and bipedally on treadmill. When the results came out humans had used only one quarter of the energy the chimpanzees had used while knuckle walking.

Refer to the Biochemistry in Focus section of your text for this chapter to answer this question. A mutation in Complex I decrea
quester [9]

Answer:

Complex II

Explanation:

The electron transport chain refers to a group of electron transporters embedded in the inner mitochondrial membrane that transfer electrons from electron donors to electron acceptors which undergo redox (reduction and oxidation) reactions. The energy released during the transfer of electrons is coupled to the transfer of protons (H+) from the mitochondrial matrix into the intermembrane space, generating an electrochemical gradient that is then used to synthesize ATP. Complex I and Complex II are membrane-bound complexes that act as mitochondrial redox carriers. Complex I is a proton pump that uses energy from the electron transfer chain to pump protons, while Complex II sends H+ onto Complex III in the form of the reduced ubiquinol. Complex I receives electrons from NADH and transfers them to ubiquinone, while Complex II directly receives the redox cofactor FADH2 that does not pass through Complex I.

Select the correct days.
san4es73 [151]

Answer:

Monday, Saturday, and Sunday

Explanation:

To decide which days would be okay for her team to conduct the experiment that involves, canopy fogging, here are some information and facts that we should have in mind:

1. Canopy fogging is a technique employed in the collection of insects in the study of forest insects. It basically involves the use of a chemical that would only affect only insects, such as pyrethrine.

2. A sprayer, which may be in the form of a machine is used in spraying this chemical in the form of aerosol with the aid of a blower.

3. Living insects are mostly collected this way for research and studies.

4. Canopy fogging is not usually done when the weather is windy and/or raining. Wind and rain would disrupt the effectiveness of the chemical used in fogging. Wind would blow away the tiny particles of the chemicals being sprayed. Rain may also wash away the particles, and rain might come with storms, hence wind would be present also.  

5. Canopy fogging can be done in a sunny and windless weather with no storm.

<em>So therefore, </em><u><em>Monday, Saturday and Sunday</em></u><em> should be ideal days for carrying out canopy fogging since rain and/or wind are absent in these days. </em>

Can wind travel faster than the speed of sound?
Zigmanuir [339]

Yes, wind can travel faster than the speed of sound. Wind is just the bulk movement of a mass of air through space and is in principle no different from a train speeding along or a comet zipping through space.

What is the concentration of KCl if 10 g are dissolved in enough water to make 12 L?
Y_Kistochka [10]

Answer:

Concentration = 0.011 M

Explanation:

Molarity is given by dividing number of moles by volume in Liters

Molarity = moles/volume

But;

Number of moles = mass/molar mass

                              = 10 g/ 74.55 g/mole

                             = 0.134 moles

Therefore;

Molarity = 0.134 moles/12 L

              = 0.011 M
