Answer:
False
Explanation:
Bacteria do not have organs like humans. However, bacteria have specific structures to perform certain essential functions.
Among the bacteria, there are the respirators, which perform aerobic cell respiration, where oxygen gas is the final acceptor of hydrogen ions. Also, some bacteria perform anaerobic cell respiration. In those, oxygen gas is replaced by other molecules, which function as hydrogen acceptors such as nitrates or sulfates. Bacteria respiration occurs through the mitochondria.
In addition, bacteria can have different forms of "obtaining food"
Some can obtain their food through photosynthesis, degrading organic compounds. Other types of bacteria use the energy released in oxidation reactions of inorganic compounds, such as those that participate in the nitrogen cycle.
Finally, there are saprophagic bacteria, which obtain food from corpses and the remains of living beings, and the parasite ones, which find this food in the tissues of living beings, often causing them illness.
When a single species, such as ancestor of the Galapagos finches, has evolved into several different forms that live in different ways we say that_ has occurred.
A.adaptive radiation
B.coevolution
C.mass extinction
D.punctuated equilibrium
Answer:
A
Explanation:
In evolutionary biology, adaptive radiation is a process in which organisms diversify rapidly from an ancestral species into a multitude of new forms, particularly when a change in the environment makes new resources available, alters biotic interactions or opens new environmental niches.

Which statement best describes a characteristic of an ecosystem
Answer:
Infrastructure
Infrastructure is an important characteristic as it influences accessibility to the environment by land managers, and tourists alike. Unfortunately it can also increase the invasive potential introduced species, such as weeds and feral animals as road vehicles are well known to act as vectors for invasion of both weeds and feral animals. On the other hand roads improve access to implement various management programs, and also provide access for land users.

Which organism in the food web below is likely to store the most energy?
boa constrictor
beetle
coati
poison dart frog
sloth
strangler fig
fungus
fruit bat
A. Strangler fig
B. Boa constrictor
C. Beetle
D. Poison dart frog
Answer:
Beatle
Explanation:
Beetle in the food web below is likely to store the most energy. So, the correct option is (C).
What is Food Web?A food web is defined as the natural interconnection of food chains and is a graphical representation of what-eats in an ecological community. Food web is also known as consumer-resource system.
A food web consists of many food chains while a food chain follows only one path as animals find food. For example, Falcon eats snake, which has eaten frog, which has eaten grasshopper, which has eaten grass. Thi shows the many different pathways that plants and animals are connected.
In this, the lower trophic level organisms have more energy than the upper trophic level because only 10% of the energy flows from one trophic level to the next. In the above case, beetles have the highest energy compared to other organisms.
Thus, Beetle in the food web below is likely to store the most energy. So, the correct option is (C).

A. Meiosis
B. DNA Replication
C. Crossing Over
Answer:
C. Crossing Over
Explanation:
Crossing over, also called recombination, is the process by which non-sister chromatids of homologous chromosomes exchange a segment of their chromosomal material with one another. The process of crossing over occurs only in the prophase I stage of meiosis.
The process is responsible for genetic variation in the gametes produced, thereby, leading to organisms that are genetically unique.
Answer:
C. Crossing Over
Explanation:
The crossing over is called when genetic information is exchanged between homologous chromosomes during prophase 1.
