How many jaguars still exist?
Estimates range from 15000 to 30000.
What is fine sand?
The term sand applies to small grains of rock in a given size range, but that range allows for some variation in size. Fine sand is sand with grains toward the small end of that range. The opposite in ths case is coarse sand.
What is a icicone?
Does not exist. Did you mean an ICI cone and plate viscometer? A viscometer with a viscosity range of 5 poise at a rate of shear of 10,000 reciprocal seconds is what that is. Hope I helped :) maybe have a look at Ask.com if this is not the right answer.
Population of animals?
A population of animals is a group of animals of the same kind, same species, have the same characteristics, living in the same habitat. For example, a population of frogs at a pond. A population of squirrels in a tree.
How many Indian elephants are left?
Indias elephant population is estimated between 10,000 and 15,000, the largest in Asia. About half of these are found in the northeastern states of Assam, Arunachal Pradesh and Meghaiaya located in far northeastern India
What kind of variation must exist in population that has a wide range of phenotype?
Gene Flow
Tends to favor phenotypes at one extreme of the range of variation?
This is called directional selection, where the environment selects for individuals with traits at one extreme of the phenotypic range. Over time, this can lead to a shift in the average phenotype toward that extreme.
Directional selection tends to eliminate?
Directional selection tends to eliminate individuals at one extreme of a trait spectrum, favoring those at the opposite extreme. Over time, this can lead to a shift in the average value of the trait within a population.
What term is used by biologists to describe the differences within a population with respect to features such as height?
The term used by biologists to describe the differences within a population with respect to features such as height is "variation". Variation refers to the range of different traits or characteristics that individuals within a population exhibit, including height.
When stabilizing selection acts to eliminate extremes at both ends of a range of phenotypes the frequencies of the intermediate phenotypes increase or decrease?
Increase, of course.
Does sexual reproduction cause a narrow range of variation or a wide range of variation in species?
SIM=
Does sexual reproduction cause a narrow range or variation or a wide range of variation in species?
SIM=
When stabilizing selection acts to elimination extremes at both ends of a range of phenotypes the frequencies of the intermediate phenotypes increase?
That is the definition of stabilizing selection.
Selection causes the range of phenotypes to become narrower increasing the number of individuals with charactertics near middle of the range?
Yes, selection tends to favor individuals with certain traits that are advantageous in their environment. This can lead to the reduction in the range of phenotypes as individuals with less favorable traits are selected against, resulting in more individuals with characteristics closer to the optimal range.
What is the likely mechanism of inheritance for a character with a large range of phenotypes Explain?
mech and cromosomes
What causes a wide range of phenotypes for some traits?
Some traits, such as eye color and hair color, have multiple alleles that control different aspects of the phenotype. Because there are multiple different possible combinations of alleles, you get a wide range of phenotypes.
In Statistics what is a quantity that measures the variation of a population or sample relative to its mean?
Inter-quartile range, other percentile ranges, mean absolute variation, variance, standard error, standard deviation are all possible measures.
