25 POINTS!! Survival of the Fittest is due to having the possession of what?
1: Adaptation
2: Competition
3: Use and disuse
4: Overproduction
Answers
Survival of the Fittest is due to having possession of Adaptations (Option 1).
What is an adaptation?An adaptation is a type of feature/trait in an organism that confers an advantage against other organisms in an environment.
Adaptations are fundamental to face challenging environmental conditions for different organisms.
The main evolutionary force by which different adaptations are favored in nature is natural selection.

In this experiment, researchers placed a pair of lizards from Iron Cay, which has large trees, in an experimental island, which has only small bushes and grass. After several generations, they measured the leg length of 10 lizards from each site. Which group of lizards had longer legs on average?
A. The ones on Iron Cay
B. The ones on the experimental island
C. There is little or no difference between the two samples
D. The difference between the two samples is too large to be conclusive
On average, the lizards from Iron Cay seem to have longer legs than the lizards living on the experimental island. We know this because the sample means + 2 SEMs (the 95% confidence intervals) do not overlap. However, to know whether the difference between the means is statistically significant you would need to use a statistical test like the student t-test

Based on inheritance patterns, se_x-linked traits are present on the se_x chromosomes while autosomal traitsare found on the autosomes.
What is a dominant allele?A dominant allele is a copy of a gene which always appears in every generation.
A pedigree is a chart that shows the inheritance of triats in generations of families.
Based on the pedigree given:
The genotype of the individual #1 is XBXb since the offspring are XBXb and XbYIn the pattern of inheritance, all males receive their X chromosome from their mother.
Se_x-linked pedigrees differ from autosomal pedigrees because the traits are located on the se_x chromosomes.

Is this animal a carnivore or an herbivore? How do its teeth help it obtain food?
Answers
Answer:
This animal is a herbivore. The front teeth help it tear off vegetation, and the back teeth help it chew the plants.
Explanation:
A herbivore's back teeth are adapted to help it chew its high fiber plant diet. The front teeth, however, help it actually put the food in its mouth. The picture below shows a typical goat skull (herbivore), and as you can see, it is similar to the one in your problem. So, that skull is one from a herbivore.

Two unlinked loci affect mouse fur color. nn or nn mice are agouti. mice with genotype nn are albino because all pigment production is blocked, regardless of the phenotype at the second locus. at the second locus, the a allele (agouti coat) is dominant to the a allele (black coat). what would be the result of a cross between two agouti mice of genotype nnaa?
Answers
The result of a cross between two agouti mice of genotype nnaa are albino offspring because mice with genotype nn are albino (pigment production is blocked by epistasis).
What is epistasis?Epistasis is a genetic phenomenon where the presence of a gene variant alters a phenotype influenced by other genes.
A gene is epistatic when a variant (allele) can alter the expression of another gene in the same signaling pathway.
Epistatic interactions are very common in nature and many traits are influenced by this type of interaction.

These are composed of intersecting horizontal and vertical lines that form a cartesian plane.
Answers
, The number plane, or Cartesian plane, is divided into four quadrants by two perpendicular lines called the x-axis, a horizontal line, and the y-axis, a vertical line. These axes intersect at a point called the origin. Once a unit distance has been chosen, the position of any point in the plane can be uniquely represented by an ordered pair of numbers (x,y). For the point (5,3), for example, 5 is the x-coordinate and 3 is the y-coordinate, sometimes called the first and second coordinates. When developing trigonometry, the four quadrants are usually called the first, second, third and fourth quadrants as shown in the following diagram.
