Answer:
e. all of the above
Explanation:
Photosynthesis and respiration are two complementary processes.
Photosynthesis occurs in chloroplasts. The electron transport chain is placed in the thylakoid membrane, where it occurs light-dependent reactions.Respiration occurs in mitochondria, in the internal membrane, where is the electron transport chain.Photosynthesis needs solar radiation to produce organic compounds.The respiration process needs organic compounds to obtain chemical energy.Photosynthesis transforms CO₂ into organic compoundsRespiration transforms organic compounds into CO₂.In the photosynthesis process occurs a release of oxygen, which is used during the respiration process. Both processes are part of the carbon biological cycle.Both processes use electron transport chains to capture energy, which will be used in other cellular reactions.Respiration´s final products are CO₂, ATP, and waterPhotosynthesis´s final products of light-dependent reactions are oxygen, ATP, and NADPH.Two of the five types of taste buds are activated by directly hypopolarizing the taste buds; i.e. do not involve a second-messenger pathway. The tastes that activate these receptors are:
Answer: salty and sour
Explanation:
Taste buds consist of the taste receptor cells and they're the nerve endings on the tongue that provide the sense of taste.
Based on the information given, the tastes that activate these receptors are salty and sour. The tastes depolarize the cell receptor directly.

Discuss the sensory neurons for vision. What are the two
types of sensory neurons for vision? Where are they located?
What are their functions in the eye? What path does visual
input take AFTER reaching the sensory neurons (be specific,
outlining the entire path to the destination point of the brain)?
Answer:
Olfactory sensory neurons (OSN).
Explanation:
Olfactory sensory neurons (OSN) are the sensory neurons that is responsible for vision. Photoreceptors and olfactory sensory neurons (OSN) are the two types of sensory neurons for vision. Both olfactory sensory neurons (OSN) and photoreceptors is responsible for the receiving of photons and enable us to see things. The right half of the visual field will travel in the left optic tract, while on the other hand, the stimuli from the left half of the visual field will pass through the right optic tract.
Answer: The two types of sensory neurones are the CONES and RODS. Their functions are better outlined below
Explanation:
The CONES and RODS are the sensory neurones ( photoreceptors) of the eye which are located in the retina.
The RODS: They are extremely sensitive and can detect light of very low intensity. They also perceive light in black and white. They, therefore, play an important role in dim light.
The CONES: They function in bright light and are responsible for colour vision.
The path visual input take AFTER reaching the sensory neurons is as follows:
--> the rods and cones are stimulated
--> A pattern of electrical impulses is sent to the brain through the optic nerve which interprets it, drawing on past experience.
The brain tells us that the object is upright and gives us it's real size and distance from the eye. We, therefore, see the object as it actually is, and not as the image formed on the retina.
The science community has taken the following stance on Global Climate change. "Climate change is the single biggest environmental and humanitarian crisis of our time. The Earth's atmosphere is overloaded with heat-trapping carbon dioxide, which threatens large-scale disruptions in a climate with disastrous consequences. We must act now to spur the adoption of cleaner energy sources at home and abroad."

Which group of bacteria reduces nitrate to nitrogen gas in the nitrogen cycle? Nitrogen fixing bacteria C. denitrifying bacteria Ammonium ion forming bacteria D. photosynthetic bacteria
Answer:
C. denitrifying bacteria
Explanation:
Nitrogen cycle consists of series of processes that add and remove nitrogen from the soil and atmosphere. There are several ways in which nitrogen can be added to the atmosphere including nitrification, ammonification, lightning etc.
Certain bacteria are responsible for the conversion of nitrogen from one compound form to another. In a process called DENITRIFICATION, nitrate (NO3-), which is the usable form of nitrogen by plants, is converted back to atmospheric nitrogen (N2) with the help of a bacteria called DENITRIFYING BACTERIA e.g Pseudomonas etc.
