Solar energy absorbed by chlorophyll necessary for photosynthesis
The energy absorbed by chlorophyll is not directly used
The energy absorbed by a molecule of chlorophyll b is not used directly for photosynthesis, but is passed by a resonance transfer mechanism to a molecule of chlorophyll a. A similar transfer of energy takes place when a carotenoid molecule absorbs a quantum of radiation.

this type of asexual reproduction is primarily used by bacteria, where the organism splits in half
Answer:
Binary Fision
Explanation:
Fission, in biology, is the division of a single entity into two or more parts and the regeneration of those parts to separate entities resembling the original. The object experiencing fission is usually a cell, but the term may also refer to how organisms, bodies, populations, or species split into discrete parts.

In some deserts, the air temperature can change over 60 to 70 degrees in a single day. Which of these properties
would allow humans to survive in an environment that has such drastic changes in temperature?
Eliminate
A)
cold bloodedness
being endothermic
being ectothermic
being photosynthetic
Answer:
Being endothermic
Explanation:
Humans are not cold-blooded and we don't photosynthesise so only the second option applies to humans;
We produce heat internally within our bodies so we are endotherms, i.e. warm-blooded;
We shiver and have thermogenesis through metabolism to generate heat to keep body temp up and also sweating and physiological mechanisms to cool out bodies down.

Identify the chemical process that plants use to create their own food.
A.chlorophyll
B.gametophyte
C.photosynthesis
D.sporophyte
Answer:
The chemical process is C. Photosynthesis.
Explanation:
Chlorophyll are organelles in plant cells that execute the chemical process to convert sunlight, CO2 and water into sugar and nutrients, and are not the process itself.
Gametophytes are the sexual phase of plants and certain algae, and are definitely not a chemical process that plants use to create food.
Sporophytes are one of the life stages in the life cycle of a plant or alga. Hence, it is definitely not a chemical process either.
Therefore, the answer is C. Photosynthesis. It is a chemical process that plants use to create their own food, and is the chemical process that chlorophyll execute to create food.

Do you think research on inhospitable plants can help botanists in other industries? Explain your answer.
Answer:
These plants grow in very difficult environments. So, researching their genes may help botanists working in agricultural areas develop crops that can grow in inhospitable areas. Also, understanding how these plants survive in harsh conditions may help conservation scientists protect plants if their environments change.
Explanation:
Predator populations decrease if the number of prey increases. true or false
Predator populations decrease if the number of prey increases is a false statement. Because if the prey increased, the predators would have more food.
What is the relationship between predator and prey?Predator-prey cycles are based on a feeding connection between two species: if the prey species quickly reproduces, the number of predators rises, until the predators eventually consume so much prey that the prey population declines again. Soon after, predator populations also decline as a result of famine.
Increased prey population expansion reduces system stability. This unexpected outcome is a result of the two populations' constructive comments. When there is more prey, there are more predators. When there are more predators, there are less prey.
Therefore, when there is less prey, there are fewer predators.

Patterns of inheritance within organisms like pea plants, fruit flies, mice, and others are somewhat easy to determine since their mating practices can easily be controlled. Apart from controlling who mates with whom, what other characteristics make species like these ideal for studying genetics?
Answer: Due to following reasons these organisms are useful for studying genetics.
Explanation:
These organisms offer following characteristics which help in understanding the inheritance pattern in living organisms:
1. They allow which traits can be inherited from the parents to the offsprings.
2. These organisms are easy to grow and cultured.
3. These organisms can bred rapidly and can show many observable characteristics.
