Cyan is a color that is formed from then combination of green and blue light. It is a greenish-blue color. It has a predominant wavelength of between 490–520 nm and wavelengths of between green and blue.
Primary colors consists of red, blue and green.
When Cyan is placed under white light, it doesn’t detect the primary color red. It only detects blue and green.

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.

Which of the following characteristics would identify this cell as eukaryotic? Please answer ASAP.
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

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.

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.

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.

What are the correct order of steps of binary fission from first to last?
Answer:
Explanation:
Step 1- Replication of DNA
The bacterium uncoils and replicates its chromosome, essentially doubling its content.
Step 2- Growth of a Cell
After copying the chromosome, the bacterium starts to grow larger in preparation for binary fissions. It is followed by an increase in cytoplasm volume as well as an increase in the number of organelles. Another prominent trait of this stage is that the two strands migrate to opposite poles of the cell.
Step 3-Segregation of DNA
The cell elongates with a septum forming at the middle. The two chromosomes are also separated in this phase.
Step 4- Splitting of Cells
A new cell wall is formed at this phase, and the cell splits at the centre, dividing the parent cell into two new daughter cells. Each of the daughter cells contains a copy of the nuclear materials as necessary organelles.
Binary fission begins with the replication of DNA. The DNA is copied. The cell elongates. The DNA is pulled toward both ends of the cell. A new septum is formed. Cytokinesis occurs. The septum is completed as a cell wall. The cells are divided in two.
The steps of binary fission can also be explained with the help of amoeba as an example.
First, an amoeba divides into two nuclei and replicates. The nuclei divide and migrate to opposite sides of the parent cell. Then, the cell produces proteins and nutrients to prepare for binary fission, in which it divides and forms two daughter cells.

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.
