Answer:
No, it would be impossible
Explanation:
Heterotrophs are so called because they cannot synthesize their own food, they depend on an external source. The synthesis of food is unique to a particular set of organisms called AUTOTROPHS. They have the ability to capture the energy from sunlight using pigments called CHLOROPHYLL and use this energy to synthesize their food in their Chloroplast. This process is called PHOTOSYNTHESIS. Autotophs combine CO2 and H2O (water) to produce glucose (organic molecule).
Heterotrophs like animals, do not possess this ability to capture sunlight energy or fix carbon to produce their food. Hence, in an abundance of CO2 and water, their cells would be unable to utilize these molecules, as only the Chloroplast of autotophs can undergo this process.
The cerebral cortex has two _____, each of which is further divided into four _____.
This scientist focused his study on planetary motion.one of his laws is the planets orbit the sun in elliptical patterns.
Answer: Johannes Kepler
Explanation: Johannes Kepler was the German astronomer and mathematician who first wrote the defense of Copernicus's heliocentric system. He was one of the most important scientists during the scientific revolution, and is best known for his three laws of planetary motion. He found that all planets, when rotating around the sun, are moving along elliptical paths, not circular ones.

The pH indicator bromothymol blue turns yellow when CO2 gas is added to a solution and blue when CO2 is removed from a solution. An experiment will test how the intensity of light affects the rate of photosynthesis in algae. Which of these should be a control for this experiment?
A. Algae that are placed in a yellow solution and keep in the direct sunlight.
B. Algae that are placed in a blue solution and kept in direct sunlight.
C. Algae that are placed in a yellow solution and kept in the dark.
D. Algae that are placed in a blue solution and kept in the dark.
Answer:
The correct answer would be C. Algae that are placed in a yellow solution and kept in the dark.
In a scientific experiment, a control is a variable which is kept constant or unchanged throughout the experiment.
The results of other variables are compared with the control.
It increases the reliability of an experiment.
In the above experiment, algae must be kept in dark in order to prevent photosynthesis and thus, it prevents the utilization of carbon dioxide.
Similarly, the yellow color solution would also act as control as it would help in observing if any carbon dioxide is utilized from the solution. The utilization or removal of the same would convert the solution blue in color.

Eric’s body returned to its state of constant internal environment after the traumatic incident by which process below?
what is the difference between an atom and an ion.
Answer:
atoms are neutral or they have equal number of proton and electron but ions can be cation(positively charged) or anion(negatively charged) based on the number of electron the atom lose and gain respectively.
Through the process of photosynthesis, plants remove carbon dioxide from the air, while producing oxygen and sugar. In space, plants canl serve two main functions: oxygen production and food supply. A plant’s ability to supply the oxygen needs for a person depends largely on the species of plant and the intensity and quality of light it receives. Plant systems can also be used to help purify wastewater. Water evaporates from the leaves and resultant humidity can be condensed as a source of clean water. At very high light intensities, wheat could supply much of one human’s food and all their oxygen needs from an area as small as 15 square meters. At moderate light intensities, a mix of crops could supply a more complete diet for one person from about 50 square meters.

Photosynthesis is the process by which autotrophs or green plants synthesize their food from carbon dioxide and water in the presence of chlorophyll and sunlight.
The oxygen is released as the byproduct of the process.
The overall equation can be written as:
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
Thus, carbon dioxide and water are the essential substrates for this process.
Hence, the absence of atmosphere and water would be the biggest issues with the given task.
A population is growing at a rate of 2 ,4, 8, 16, 32. Which type of growth does this describe?
The right answer is exponential.
In mathematics, economics and biology, we speak of an exponential (or geometric) growth phenomenon when the growth in absolute value of the population is proportional to the existing population, ie when the growth rate intrinsic is constant and positive.
When the phenomenon of exponential growth is continuous, we can model it by means of an exponential function: Nt = N0 exp (r.t)
N (t) is the number of individuals at time t, N (0) the number of individuals at time 0, r the intrinsic growth rate and t time, exp () being the Euler constant of approximately 2.718 .
Which of these is a finger-like sac that has no known function in humans?
Which of these statements is true with regard to this animation? which of these statements is true with regard to this animation? sodium and potassium ions are transported against their concentration gradients. the cell is not expending energy. sodium ions are transported down their concentration gradient. potassium ions are transported down their concentration gradient. the cell does not expend atp?
Final answer:
Sodium and potassium ions are actively transported against their concentration gradients by the sodium-potassium pump, a process that requires ATP, thus the cell expends energy.
Explanation:
The statement true with regard to the animation of the sodium-potassium pump is that sodium and potassium ions are transported against their concentration gradients. This process is an example of active transport and indeed requires energy in the form of ATP. This mechanism is crucial for maintaining the electrochemical gradients necessary for various cellular processes, including the propagation of nerve impulses in neurons.
The sodium-potassium pump actively transports sodium ions out of the cell and potassium ions into it, despite there being a higher concentration of sodium ions outside the cell and a higher concentration of potassium ions inside. This creates and maintains the necessary ion gradients. As part of this active transport system, ATP is hydrolyzed to provide the energy required for the pump to work, indicating that the cell does indeed expend energy - specifically ATP - in the process.
Water molecules are ____________ due to _________bonding. This property helps water molecules to stick to each other and allows for the movement of water from plant roots up to plant leaves
Answer: cohesive , hydrogen
Explanation: Cohesion is the force of attraction between similar molecules. Water molecules are cohesive due to hydrogen bonding. This property of water allows the molecules of water to stick to each other.
Water forms hydrogen bond due to the presence of hydrogen atom and a electronegative oxygen atom. The formation of hydrogen bonds leads to the cohesive nature of the substance allowing plants to transport water from their roots up through stems to their leaves due to capillary action which is also a result of hydrogen bonding.
The orbital cavities , nasal cavity, paranasal sinuses, and the oral cavity are all located in what region of the body
These are all part of the head or skull. The cavities of the skull surround and protect the brain and sensory organs. There are five kinds of cavities of the skull which are:
nasal cavity (paranasal sinuses is included here) - The nasal septum split the respiratory system into two lateral halves, the nasal cavity is also part of the respiratory system.
cranial cavity - The large cranial cavity is split into a posterior cranial fossa and an anterior cranial fossa, a middle cranial fossa. Its function is to support the brain.
oral cavity - The oral, or buccal, cavity (commonly called the mouth) is a cavity of the head rather than a cavity of the skull because of its fleshy and muscular floor.
orbital cavity - supports and defends an eyeball and its linked muscle, vessels, and nerves.
middle ear cavity - From outer to inner, three small bones-malleus, incus, and stapes are situated within the middle-ear cavities in the petrous part of the temporal bones.

What ethical issues could arise from using embryonic cells as opposed to adult stem cells?
Stem cell research offers great promise for understanding basic mechanisms of human development and differentiation, as well as the hope for new treatments for diseases such as diabetes, spinal cord injury, Parkinson’s disease, and myocardial infarction. However, human stem cell (hSC) research also raises sharp ethical and political controversies. The derivation of pluripotent stem cell lines from oocytes and embryos is fraught with disputes about the onset of human personhood. The reprogramming of somatic cells to produce induced pluripotent stem cells avoids the ethical problems specific to embryonic stem cell research. In any hSC research, however, difficult dilemmas arise regarding sensitive downstream research, consent to donate materials for hSC research, early clinical trials of hSC therapies, and oversight of hSC research. These ethical and policy issues need to be discussed along with scientific challenges to ensure that stem cell research is carried out in an ethically appropriate manner. This article provides a critical analysis of these issues and how they are addressed in current policies.
