Answer:
Differences in beak shapes tell us that all the finches eat the same type of food. Different finch beak shapes are evidence that all Galápagos finches shared a common ancestor a long time ago. Different finch beak shapes are evidence that over time, finch species adapted to different food sources on the islands.
Explanation:
How has shark skin been used to inspired materials that slide faster through the water?
Answer:
Shark skin has been used by many cultures as sandpaper. It's kept shipmates safe in slippery-when-wet conditions. Swimsuits modeled on shark skin are said by Speedo to reduce drag by up to 4 percent. Now, research by two separate groups could lead to synthetic shark skin that would make ships and submarines faster and less expensive to operate.

Chemical waste is a waste that is made from harmful chemicals (mostly produced by large factories). Chemical waste may fall under regulations such as COSHH in the United Kingdom, or the Clean Water Act and Resource Conservation and Recovery Act in the United States.
[ Impact of Chemical Waste on Water Streams. Improperly managed chemical waste may pollute and contaminate water streams. There are many causes of this type of industrial water pollution, which has both serious and negative impacts on aquatic and human life.]
Cattle live in an area where the streams are dry. For which basic need do these cattle most likely compete?
a food
b shelter
c water
d energy
Answer:
c
Explanation:
Competition for water is likely to be more important to the cattle than competition for food, shelter, or energy, as these other needs can typically be met through other means. Therefore,option (C) is correct.
Why cattle need water to survive?Cattle, like all living organisms, require a consistent supply of water in order to survive. In the passage, it is mentioned that the streams in the cattle's area are dry, which means that there may be limited access to water in this area. Cattle, also known as cows or bovines, are large, hoofed mammals that are domesticated for their milk, meat, leather, and other products. They are typically raised on farms or ranches, and are known for their docile and gentle nature. Cattle are herbivores, and are typically fed a diet of grass, hay, and other plant materials
As a result, the cattle may have to compete with one another for access to water, as it is a basic necessity for survival. In this situation, competition for water is likely to be more important to the cattle than competition for food, shelter, or energy, as these other needs can typically be met through other means.

Which of the following symbiotic relationships is considered parasitic?
A. Tapeworm in an intestinal tract
B. Bees transporting pollen from flowers
C. Pilot fish swimming under sharks
D. Birds eating the insects from the back of a hippopotamus
Answer:
A. Tapeworm in an intestinal tract.
Explanation:
This symbiotic relationship is parasitic because the tapeworm causes harm to the host. Tapeworms feed off the nutrients the host consumes, thus making the host sick.
Not parasitic:
Bees transport pollen from flowers back to the nest to feed the young bees, but pollinate female flowers as well which keeps the flower population alive.
Pilot fish swim under sharks to keep other prey from eating them, and the shark do not eat eat the pilot fish.
Birds eating the insect of the back of a hippopotamus keep the hippo clean and parasite-free as well as feeding the birds.
The presence of tapeworm in intestinal tract is considered parasitic. Thus, the correct option is A.
Symbiotic relationships refers to the association between two two organisms belonging to different species. There are three types of symbiotic relationships which are mutualism, commensalism and parasitism.
In mutualism, both of the organisms involved are benefited from the relation.
In commensalism, one of the organisms involved is benefited and the other is neither benefited nor harmed from the association.
In parasitism, one of the organisms involved is benefitted and the other one is harmed from the association.
As in the relationship between tapeworm and human, tapeworm is benefited but the human involved is harmed. Thus, it is a parasitic relation.
Thus, the correct option is A.

When population grows past the ecosystem’s carrying capacity, what happens to the population?
A. Continues to grow
B. The population starts to die off to return to carrying capacity
C. The population will go extinct due to lack of resources
D. The population grows, then finds a new carrying capacity.
Answer:B animals will die since there arent enough resources for everyone until there is enough for the remaining population to use
When Population growth past the ecosystem’s carrying capacity, then the population starts to die off to return to carrying capacity (Option B).
The carrying capacity refers to the maximum number of individuals of a population that can be supported by particular environmental conditions.Carrying capacity depends on both biotic factors (e.g., presence of predators, food availability, etc.) and abiotic factors (e.g., water availability, living space, etc).When a population passes its carrying capacity, then the environment becomes unsuitable for the individuals of that population to survive.In conclusion, when population growth past the ecosystem’s carrying capacity, then the population starts to die off to return to carrying capacity (Option B).

what forces cause surface ocean circulation? what forces cause deep water circulation?
Answer:
ANS 1) Ocean currents can be caused by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes or storms. Currents are cohesive streams of seawater that circulate through the ocean.
ANS 2)n the deep ocean, the predominant driving force is differences in density, caused by salinity and temperature variations (increasing salinity and lowering the temperature of a fluid both increase its density). There is often confusion over the components of the circulation that are wind and density driven.

Skin color, fur color, and height are examples of which inheritance pattern?
A. Mendelian inheritance
B. incomplete dominance
C. codominance
D. polygenic inheritance
Answer:
D
Explanation:
Skin color, fur color, and height are examples of polygenic inheritance. Thus option D is correct.
What is polygenic inheritance?Polygenic inheritance is defined as a type of heredity where the trait is created by the interactions of many genes, as opposed to monogenic inheritance where the phenotype is created by the expression of just one gene.
When numerous separate genes have an additive or comparable effect on a single quantitative characteristic, this is known as polygenic inheritance.
Multiple gene or multiple factor inheritance are other names for polygenic inheritance.
The some of the characteristics are since epistasis is not at play, the expression of one gene is not obscured by the existence of the other genes. There are no dominant or veiled genes; the gene involved in polygenic inheritance is either contributing or non-contributing.
Thus, skin color, fur color, and height are examples of polygenic inheritance. Thus option D is correct.

D. treeless, permafrost, cold dark winters
Answer:
D. treeless, permafrost, cold dark winters
Explanation:
The correct answer would be D
Tundra is a habitat in which tree growth is hampered by cold temperatures and short growing seasons. Therefore, option (D) is correct.
What is a tundra?The freezing temperatures and short growing seasons of a tundra biome make it difficult for trees to develop in this sort of ecosystem.
Most of the time, it is cold, but in the summer, it can get quite warm. The winters on the tundra are long, dark, and very cold. For six to ten months of the year, temperatures are below 0 degrees Celsius. Because the temperatures are so low, there is a layer of frost below the surface. This is a layer of frozen ground.
Arctic tundra is found above the Arctic Circle in Alaska, Canada, Russia, Greenland, Iceland, and Scandinavia, or in Antarctica. Alpine tundra are high on mountains where nightly temperatures are below freezing.
Therefore, option (D) is correct.
