Answer:
I'm pretty sure it is 'some species depend on disterbences'
The potential benefit of a disturbance to a community is that some species depend on disturbances.
Importance of disturbance in a communityCommunity disturbance can be defined as a force, which may be biological or non biological, that results in mortality of organisms or loss of biomass.
Different types of disturbance that can affect a community include:
fires, storms, diseases, volcanic eruptions, earthquakes, contaminant spills, and land clearing.Some species depends on community disturbance because the cleared habitat caused by the disturbance leads to species movement into the newly cleared area, that is, secondary succession.

Which statement explains why the structure of sickle cells differs from normal red blood cells?
a. The gene mutation affected protein synthesis.
b. The gene mutation prohibited DNA replication.
c. The gene mutation inhibited the cell's ability to produce tRNA.
d. The gene mutation affected the cell's ability to produce ATP.
Answer:
A. the gene mutation affected protein synthesis
Explanation:
Basically, sickle cell results due to point mutation (change in one nucleotide) in DNA, which in turns affects the mRNA produced and finally the protein made from that mRNA is affected. I have listed a helpful image below which shows that the mutation actually results in formation of an undesired protein which causes sickle cell to occur.
What evidence does not support the evolution of chloroplasts and mitochondria from prokaryotic cells?
A. Fossilized remains of archaebacteria

Black bears in the north hibernate mostly due to the scarcity of food during the winter months.
Prior to hibernation bears are foraging for food. They eat fruit, nuts, acorns, insects, and certain leaves and plants. They catch occasional small animals, but lack agility to catch most adult prey. In the months before hibernation black bears can gain up to forty pounds of fat per week.
9. What types of food molecules is the bear consuming (give at least two)?
Answer:
Food having high fat.
Explanation:
The bear eat food products having high fats in order to store it in the body. The food which have large amount of protein and fats are stored in the body and helps in gaining of weight up to forty pounds of fats per week. During hibernation period, bear used this fats for the release of energy used for its survival. Fats produce huge amount of energy when they are broken down so this fats helps in hibernation of bear.

The _____ of a species is usually the result of predation, competition, and other types of interaction between species.
Answer: Realized Niche
Explanation:
Realized niche is also referred to as Post Competitive niche and can be defined as a thriving environmental area created by a group of organisms to survive from an exsisting Faundermental niche where interactions (predation, competition, light, water,food) with other organisms were limited and competed for.
For example. In a tree( Faundermental niche) which houses different species of birds, In order to survive, each specie of the birds will create a realized niche so as to survive from predation, competition, light etc which the whole tree provides.

Which list identifies the order of events that formed a volcanic crater?
A) CBDA
B) BACD
C) CADB
D) DBAC
Based on the given image, the order of events that formed a volcanic crater is CADB. Thus the correct option is C.
What is a volcanic crater?A nearly circular hole in the ground produced on by volcanic eruptions is known as a volcanic crater. It is a valley that typically stands just above the eruption where volcanic debris is emitted, and it has the shape of a bowl or funnel.
During volcanoes, craters' dimensions and shapes could alter. A volcanic crater, also known as a caldera, is a sizable depression created when a natural disaster occurs and then collapses.
Underneath the surface of the Earth, the molten rock is known as magma. Less dense than normal lava is being pushed upward to the surface by intense pressure. When magma seeps through layers of preexisting rock, it forms another structure.
Therefore, option C is appropriate.

When the particles are equally spaced apart they have reached:
A. Hypertonicity
B. Dynamic Equilibrium
C. Homeostasis
D. Osmolarity
Answer:
B. Dynamic Equilibrium
Explanation:
The result of diffusion is a gradual mixing of material such that the distribution of molecules is uniform. Since the molecules are still in motion, but an equilibrium has been established, the end result of molecular diffusion is called a "dynamic equilibrium".
Answer:
B. Dynamic Equilibrium
Explanation:
When the particles are equally spaced apart they have reached Dynamic Equilibrium.
A ___(J)_____ is a group of individuals of the same species that mate and produce offspring. In each generation, new genotypes occur that express themselves as specific individual ____(K)___. Any factor that affects the ____(L)___ of a population can change the frequency of ___(M)___, resulting in evolution over time. Through the processes of variation and ___(N)___, new species can arise. A ___(P)___ is a population of physically similar, interbreeding organisms that do not interbred with other such groups.
Answer:
(J) population; (K) phenotypes; (L) gene pool; (M) alleles; (N) natural selection; (P) species
Explanation:
A population is a group of organisms living in a particular geographical area that is capable of interbreeding, while a species is a group of populations that are capable of interbreeding and producing fertile progeny. In a population, genetic variation can enter from one of these sources: 1-recombination (i.e., the exchange of DNA between homologous chromosomes during meiosis), 2-mutations (i.e., genetic alterations resulting from DNA replication), 3-migration of individuals between populations, or 4-lateral or horizontal gene transfer (i.e., the acquisition of genetic material between individuals without direct vertical inheritance, it is extremely rare in higher organisms). Alleles are gene variants which are may be created, for example, through mutation, while the gene pool refers to the total genetic diversity (i.e., alleles) that exists within a population. Finally, natural selection refers to the evolutionary process of differential reproduction and survival through which populations adapt and change.

Match each of the following terms with its description. 1. Arteries a) Tiny, thin-walled blood vessels that connect the smaller arteries to venules 3. Veins 4. Venules 5. Arterioles 2. Capillaries b) Thin-walled blood vessels that are less elastic than arteries c) Thick-walled, muscular, flexible tubes that carry oxygenated blood away from the heart to the arterioles d) Small arteries that deliver blood to capillaries e) Small vessels that connect the capillaries to the veins
Answer:
Arterioles - D
Arteries - C
Veins - B
Capillaries - A
Venules - E
Explanation:
This question is describing the blood vessels that make up the circulatory system. The blood vessels with their accurate description are as follows:
- ARTERIES: Arteries are the most elastic and thick-walled blood vessels that functions to carry blood away from the heart using great pressure. Arteries are muscular, flexible tubes that carry oxygenated blood away from the heart to the arterioles.
- VEINS: Veins are blood vessels that carry deoxygenated blood back to the heart. Veins have a thin wall and are less elastic in comparison with arteries.
- CAPILLARIES: Capillaries are smallest blood vessels designated to connect the smaller arteries or arterioles to venules. They are also thin-walled.
- ARTERIOLES: Arterioles are small arteries or branches of an artery that connects the arteries to capillaries. Arterioles deliver blood to capillaries.
- VENULES: Venules are tiny veins or branches of a vein that connects the veins to the capillaries. Venules deliver blood from capillaries to veins.
