Answer:

c. single bond

b. double bond

The rest is right :)

Carbon dioxide is carried from the tissues to the lungs by a variety of mechanisms. Which of the following lists these mechanism
Yakvenalex [24]

Answer:

bicarbonate-carbaminohemoglobin-dissolved in plasma

Explanation:

Transport of CO2 in the blood occurs in three main forms. Most of the CO2 is carried in the blood as bicarbonate. It accounts for transport of about 70% CO2. In RBCs, CO2 reacts with water in the presence of the enzyme carbonic anhydrase to form carbonic acid, which dissociates into H+ and HCO3-. Bicarbonate formation also occurs in blood plasma.

About 23% of CO2 is carried in the form of carbamino-compounds. Binding of CO2 to hemoglobin forms carbaminohemoglobin. The smallest percentage of CO2 (about 7%) is dissolved in blood plasma and is diffused into the alveolar air as it reaches the lungs.

Which of the following statements best describes the carbon atoms present in grass-eating cows?
Temka [501]

Answer:

d. The carbon atoms came from carbon dioxide and were incorporated into sugars through photosynthesis in the grass.

Explanation:

Grass eating cows are heterotrophs and can not synthesize the organic sugars by themselves. They derive it from grasses they eat.  

Grasses are the autotrophs that can fix atmospheric carbon dioxide into glucose in the presence of sunlight by the process of photosynthesis. The extra glucose formed during photosynthesis is stored in the cells of grasses in the form of starch and becomes a source of carbon for herbivores such as cows.

In one paragraph, discuss the research findings. Does the study support genetics (nature) or environment (nurture) as a stronger
Viefleur [7K]

Answer:

In the study there was an experiment performed, with the experiment it was determined that twins who were separated at a young age, did not have a significant impact on their behavior. In the study scientists were surprised because the twins still had similar behaviors. That is because both twins inherited traits from their mom and dad. In the study I believe nature was more evident than nurture because even though the twins were separated they still had similar personalities. However, I do still believe that part of their personality will be influenced by their environment and the people they are surrounded.

In this study there were several research methods used. The psychologists used questionnaires to research how the twins traits and personalities develop. They also used observation, they observed the twins behaviors. But the patient and the observer could be influenced by what they are trying to discover, so this technique is biased. And they used case stud, the case studies would be the twins because they are the ones being observed and are the base of the experiment.

In one paragraph, describe the research methods used in this study and why you believe they were chosen. Be sure to use key terms such as cross-sectional research, longitudinal research, data collection, observation, case studies, questionnaires, and experimentation, as they apply. Your answer should include at least two of these key terms.

In one paragraph, discuss the research findings. Does the study support genetics (nature) or environment (nurture) as a stronger influence on human development? Use information from the article and the lesson to support your response.
