2. Most male crickets produce a mating song by rubbing together their curved
wings. In a certain geographic area, parasitic flies detected male crickets singing
and deposited their larvae into them, which killed the crickets. Eighteen
generations later, the number of males with flat wings has increased to 90%. The
flat-winged crickets do not sing, but are still able to mate with females, and
parasitic flies cannot detect them. Which type of selection is occurring in this
cricket population?

Answer:
C) presence of a nucleus
Explanation:
A is incorrect because all cells have a cell membrane
B is incorrect because a flagella does not determine whether or not the cell is eukaryotic or prokaryotic
D is incorrect because a cell wall is used to differentiate an animal cell from bacteria, archaea, fungi, plants, and algae cells
Only eukaryotic cells have a nucleus
Hope this helps :) (maybe mark me brainliest?)
Presence of a nucleus would identify this cell as eukaryotic cell. Therefore, option (C) is correct.
What are features of an eukaryote?Eukaryotes are organisms with nuclei in each of their cells. Eukaryotes include all animals, all plants, all fungi, and many unicellular creatures. They are a part of the Eukaryota or Eukarya group of organisms, one of the three categories of life.

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.

This illustration shows a strand of mRNA and the complimentary tRNA molecules that can base pair with the mRNA codons. What is the correct sequence of amino acids?
Answer:
Since you haven't attached the illustration for finding out the amino acid sequence from the mRNA sequence from, I'll explain the general principle for it.
The mRNA represents the code for translation into specific amino acids which will form the protein. A group of three bases, a triplet code, is referred to as a codon. The tRNA is responsible for recognizing the codon and matching the anticodon that will attach to the mRNA and generate the chain of appropriate amino acids.

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.

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.

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.

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.
