Answer:
Black fur is more fit to survive in the environment than other colors of fur.
Explanation:
"Fitness", in terms of natural selection, is an organism's likelihood to survive in a given environment. Assuming that the increase in black fur is significant (Not attributable to pure chance), we can safely assume this is because Black Fur provides a competitive advantage in said environment over other colors of fur. There may be black terrain that allows them to blend into the environment and ovoid predators, or maybe it keeps them warmer if it is located in a cold region, thereby reducing the amount of resources they need to spend to stay warm.
Artificial selection - The intervention of humans ensures that only individuals with the most desirable traits produce more offspring
- Farmers only breed the livestock that produce the most food..... Cow, Chicken, plant with the most vegetables
Answer:
I believe the first one would be incomplete dominance, the second would be multiple alleles, and the third would be codominance.
Explanation:
The first one would be incomplete dominance because the child has a blend of the man's straight hair and the woman's curly hair, but neither of two hair types are completely dominant (if that makes sense).
The second one would be multiple alleles because, well, there are multiple alleles listed (more straightforward than the other two).
And the third one would be codominance because the traits of red color and white color are equally dominant.
Answer:
Constant variables
Explanation:
Elaina's investigation lacked the critical ingredient of constant variables which are important components of every scientific investigation. In every research, there are 3 important variables, namely:
1. Dependent variables: the actual variable to be measured during the course of investigations and whose values are dependent on another variable (independent variable) supplied by the investigators.
2. Independent variable: one of the variables that are supplied by investigators whose values are often manipulated to see the kind of changes it will cause to the dependent variable.
3. Constant variables: other variables that are neither independent nor dependent but constant for all the various experimental groups in investigations.
Answer:
Tendon or a connective tissue
Explanation:
Tendons are a type of connective tissue that attaches muscle to bones. They are strong, fibrous and flexible. They also attach muscles to other organs. Tendons have a high tensile strength which is useful to withstand muscle contractions. They are made up of bundles of connective tissue that contribute to its strength.
