Katie and her sister have entirely different features and traits. Katie has blonde hair and brown eyes, but her sister has red hair and blue eyes. What causes these variations in traits such as hair color,eye color,and height? A. Competition b. Offspring c.Alleles d. Fitness
Answer:
c.Alleles
Explanation:
Genes are the hereditable units that transmit the information needed to specify traits (such as hair or eyes color), from parents to offspring, generation to generation. Genes are arranged in sequence in the chromosomes. A chromosome might contain hundreds of thousands of genes.
Each chromosome carries specific genes that code for specific proteins that have specific functions in the organisms. Each chromosome carries information to synthesize different proteins needed to accomplish a certain function. But not all chromosomes carry the same gene sequences. Only homologous chromosomes carry information for the same trait, but even this information is not necessarily the same. They might have the same gene but in different alternatives.
Alleles are the different alternatives in which a gene might appear. By the process of natural mutation, a gene might change into two or more alternative forms that are called alleles. These alternative forms codify for the same trait expressing different phenotypes.
In the exposed example, alleles are responsible for the different phenotypes expressed by the girls. The alternative forms of the genes -the alleles- that codify or hair color and for eyes color, express either red or blonde hair, and either blue or brown eyes.
The final genotype and phenotype depend on the gametes that merge to form the zygote, and hence the new organism.
If you have a cube-shaped with 6 sides and each sides 4 cm in length and width what will be the Surface area? Volume? Ratio of surface area to volume?
Answer:
The surface area will be 96 square centimeters(96cm^2), and the volume will be 64 cubic centimeters(64cm^3). The ratio is 3:2.
Explanation:
To find surface area, you find the area of one side of the cube, which is length x width. For a cube, the length and width are the same, so it was 4x4, which gives you 16, and then you multiply that by the number of sides, 6, to get 96.
To find volume, you multiply length x width x height, which are all 4cm for the cube.
To find the ratio, you compare the surface area to the volume similar to a fraction, except side by side. I simplified 96 and 64 by dividing them by 8, which gave me 12:8, and then I simplified that by 3 which gave me 3:2.

What distinguishes each element from all others, and gives it unique physical and chemical properties?
The physical and chemical properties of each element distinguishes form all others elements, all these properties depends upon the number of protons present in an element. Thus, the correct option is D.
What are elements?A chemical element is a species of atoms which contain the same number of protons in the nucleus. Unlike the chemical compounds, elements present in the periodic table cannot be broken down into simpler substances by any chemical reaction.
The number of protons present in the nucleus is the defining property of the chemical element. It is referred to as the atomic number, is represented by the symbol (Z). All the atoms which have the same atomic number are the atoms of same element. All of the matter present in the universe is composed of chemical elements.
Therefore, the correct option is D.

How is the process of using fossil fuels to produce electricity similar to and different from using nuclear power to produce electricity?
Answer:
The pressure of the steam turns a generator, which produces electricity. The difference is in how the heat is created. Power plants that run on fossil fuels burn coal, oil or natural gas to generate heat. In a nuclear energy plant, heat is produced from splitting atoms – a process called nuclear fission.
how does the surface area to volume ratio affect the rate of diffusion
Explanation:
As the ratio gets smaller, it takes longer for items to diffuse.
Explanation:
When the cell increases in size, the volume increases faster than the surface area, because volume is cubed where surface area is squared.
When there is more volume and less surface area, diffusion takes longer and is less effective. This is because there is a greater area that needs to receive the substance being diffused, but less area for that substance to actually enter the cell.
this is actually why cells divide. When they become too large and it takes too long for them to transport materials across the cell, they lose efficiency and divide in half to raise the surface area to volume ratio.

and from the leaf?
Veins sustain the leaf and carry nutrients and energy through the leaf and to the rest of the plant via xylem and phloem, respectively.
How does the location of the veins in a leaf affect how well they function?Veins in plants transfer water, nutrients, and energy to the rest of the plant while also giving it structure and support. Plants employ their vascular system to transport water and nutrients when they absorb them through their roots.Veins support the leaf and transport nutrients and energy to the rest of the plant via xylem and phloem, respectively.Because every cell is near a vein, it can rapidly collect water and release glucose. The cells that make up the other parts of the leaf differ from the cells that make up the palisade mesophyll in three ways.To learn more about Veins in plant refer to:
