The calvin cycle makes direct use of ________ to make ________.
Final answer:
The Calvin cycle makes direct use of ATP and NADPH to make glucose and other carbohydrates. It consists of two phases: carbon fixation and reduction, where ATP and NADPH are utilized to produce GA3P.
Explanation:
The Calvin cycle uses ATP and NADPH to convert carbon dioxide into glucose, storing energy from photosynthesis. Specifically, the cycle harnesses energy in the form of 6 ATP and 6 NADPH to produce Glyceraldehyde-3-phosphate (GA3P) molecules. These molecules store the energy captured from photosynthesis. During the cycle, GA3P is used to regenerate Ribulose biphosphate (RuBP) which continues the cycle enabling the fixation of CO2.
The Calvin cycle consists of two main phases. Initially, CO2 is fixed into an organic molecule. Subsequently, ATP and NADPH from the light reactions are used to reduce the fixed carbon into GA3P, which can then be used to form sugars like glucose.
The cycle is crucial for building high-energy carbohydrates necessary for plant growth and energy storage, demonstrating how light energy is converted into chemical energy during the process of photosynthesis.
A scientist makes a claim that two hominid species have a common evolutionary ancestor. Which of the following must happen to ensure this claim can be considered valid?
The answer would be scientific evidence must be found, verified, and accepted by the scientific community. Scientific evidence is data gathered from a scientific research, which takes a lot of time to conduct. But there are a few things that all this research needs to have in common to make it possible for decision-makers, and ultimately all of us, to admit it as “evidence”. Scientific evidence relies on data, and it is critical for researchers to guarantee that the data they collect is representative of the “true” situation. This means using showed or fitting ways of collecting and analyzing the data and ensuring the research is conducted ethically and safely. The researcher have to present their data, results and conclusions in the form of a scientific report or paper. This must be studied by their scientific peers – only they are qualified to assess the validity of the methods and the accuracy of the conclusions the researcher has drawn from the results.
Answer:
Scientific evidence must be found, verified, and accepted by the scientific community.
Explanation:
Given the following choices, D is correct:
A) The scientist's hypothesis must be reviewed and revised.
B) Funding for research must be obtained to conduct experimental trials.
C) Experiments must be conducted to determine where the species' fossils can be found.
D) Scientific evidence must be found, verified, and accepted by the scientific community.
In the annunciation of the death of the virgin (13.23), duccio employs an innovative use of __________.
In the annunciation of the death of the virgin 13.23, duccio employs an innovative use of architecture. During this period the most fervent development in painting occurred in Italy. At the end of the thirteenth century, Italian artist began demonstrating an astonishing genius for strikingly dramatic works. Incorporating the neo greek influences acquired from the fourth crusade with the gothic style and a bold new emotional intensity was exposed. The first major step eliminating painting from the architectural setting of other art forms can be seen in the Annunciation of the Death of the Virgin by the Sienese master, Duccio. Earlier painters always placed architectural features in arrears the figures which makes a new perspective of space and depth. While duccio, in structural space and depth on a two dimensional surface, opening a window onto a distant scene, giotto distilled these concepts of depth and space to startling simplicity drawing the viewer into a picture.
The ________ division of the autonomic nervous system is known as the "rest and digest" division.
Explain how the mechanism of tubular secretion and explain its importance in the urine formation process
In the process of tubular secretion, this is where the renal tubule extracts chemicals from the capillary’s blood chemicals and secretes these to the tubular fluid. The two main purposes are waste removal and the maintenance of acid-base balance. This is the process in the urine formation where urea, uric acid, bile acids, ammonia and creatinine exits to the renal tubule. This clears the pollutants in the blood as well. It is also in this process where tubular secretion of hydrogen and bicarbonate irons functions to regulate the pH of the fluids of the body.

During a science fair, a group of students came up with the following question: 'Is color an inherent property in objects or is it a product of the mind?' Why would this question be extremely difficult to answer scientifically?
A.) How people experience color varies
B.) Color is not an observable phenomenon
C.) It does not attempt to explain the natural world
D.) The experimental group would be too large.
Answer:
A.) How people experience color varies
Explanation:
This question would be hard to answer scientifically because each person has a different perception of color.
The retina, the portion of the eye responsible for capturing the image, has two groups of cells: rods and cones. Cones are the cells responsible for our color perception, and our eyes have red, blue, and green cones. However, each person carries different portions of each type of cone, generating different color perceptions. For example, a plate that you consider red may be seen as brown or pink by some people, precisely because of the difference in the proportion of the cones and how each brain receives the information.

Which two characteristics of living things do viruses exhibit PLZ HELP!!!!!!!!!!!
1.They have genetic material.
2.They increase in size over time.
3.They are made up of a single cell.
4.They eliminate waste.
5.They reproduce.
The two characteristics that viruses have same as that of living things are mentioned as under:-
1. They have genetic material & 5.They reproduce.
They have genetic material as either DNA or RNA like living beings. The genetic material of viruses is surrounded by capsid which is made up of proteins. Apart from this basic feature they have the ability to reproduce. They infect a host cell and take control of host's cellular machinery to reproduce. They use host's energy in the form ATP and use the host's resources to regenerate their own replicas. They are basically parasitic in nature because they infect a host and use its resources without providing it any benefit.
Rest of the options are incorrect. Viruses do not increase in size. They are acellular i.e. they are not cellular neither they eliminate wastes.
Answer: The two characters that viruses exhibit like that of living things are :
1. Viruses have genetic material, they carry RNA or DNA as genetic material. The nucleic acid may be double or single stranded. The virus is entirely an infectious particle. which consists of virons and outer shell which is made up of nucleic acid.
2. They reproduce: Viruses during the infection process in the target host cell reproduce and produce many viruses.

When hot, many mammals sweat to control their body temperature. evaporation contributes to temperature moderation, but mammals' ability to control their body temperature is mainly due to __________?
Answer:
Homeostatsis
Explanation:
Mammals are homoeothermic, which means they can adjust their body temperature as per change in temperature of the surroundings. This is called homeostasis.
Homeostasis is a self-regulatory process by which some organisms such as mammals, birds maintains their internal environment constant.
For examples, the body of a human body functions optimum at normal temperature which is 37°C. If the body temperature increases well above 37°C, then by self-regulatory process body bring down temperature to the normal.

Why is anaerobic respiration energetically less efficient than aerobic respiration?
Final answer:
Anaerobic respiration is less efficient than aerobic respiration because it produces less ATP per glucose molecule, due to the lack of full oxidation in the absence of oxygen and the inability to utilize the electron transport chain effectively.
Explanation:
Anaerobic respiration is energetically less efficient than aerobic respiration because it produces significantly less adenosine triphosphate (ATP) per glucose molecule. In aerobic respiration, glucose is fully oxidized to carbon dioxide, releasing enough energy to produce up to 38 ATP molecules. In contrast, anaerobic respiration converts glucose into lactate (or other byproducts, depending on the organism) in the absence of oxygen, yielding only about 2 to 4 ATPs.
The electron transport chain (ETC), which requires oxygen to function fully, generates a large amount of ATP in aerobic respiration by oxidizing NADH and FADH2. In the absence of oxygen, as in anaerobic glycolysis, these carriers cannot transfer their electrons through the ETC, hence diminishing the production of ATP. Instead, processes like lactate dehydrogenase come into play to oxidize NADH, but this does not produce additional ATP.
While anaerobic respiration is less efficient in terms of energy production, its speed is a significant advantage, allowing for rapid ATP generation which is crucial for short, intense bursts of activity such as running or lifting weights. This quick energy release can temporarily meet the high-energy demands of muscles when oxygen supply is limited or during sudden high-energy requirements.
