Why don't all species undergo sexual selection?
Not all species undergo sexual selection because some species reproduce asexually, or have other mechanisms for mating that do not involve competition for mates based on characteristics that enhance attractiveness, such as physical traits or behaviors. Sexual selection tends to occur in species where there is competition for mates, and those with certain traits are more likely to successfully reproduce.
Which type of natural selection tends to prevent evolution?
Stabilizing selection tends to prevent evolution as it favors the intermediate phenotype and reduces genetic variation in a population. This can lead to the maintenance of a stable population with limited change over time.
When is gene drift a major factor in evolution?
Gene drift tends to be a major factor in evolution in small populations, where random fluctuations can have a larger impact. It is particularly important in cases of genetic bottleneck or founder effect, where a small group establishes a new population with reduced genetic diversity, leading to increased susceptibility to gene drift.
What advantages does a species that produces sexually have over a species that reproduces asexually?
Sexual reproduction allows for changes in the lifeforms due to genetic mixing and evolution. Asexual reproduction tends to produce exact copies of the single original species with only a rare change to the genes, usually caused by radiation damage, cosmic rays and natural background radiation being two of the main sources.
What happens to the proportion of the beneficial traits in a species over time according to the theory of evolution?
According to the theory of evolution, beneficial traits in a species tend to become more common over time through a process called natural selection. Individuals with advantageous traits are more likely to survive and reproduce, passing these traits on to future generations. Over many generations, this can lead to an increase in the proportion of beneficial traits in a species.
How does reactive power change the Power Factor?
Power Factor is the relationship between the phase of the current and voltage which are each sine waves. When there is an inductance in a circuit the AC current waveform tends to lag the voltage. This causes a phase difference which reduces the Power Factor from a maximum of one to something less.
When a load on a normally excited synchronous motor is increased its power factor tends to?
power factor normally goes to the lagging
Does pepto bismol change the color of your feces?
YES! It can turn your tongue black too but I've only experienced the black stool.
Which ape species tends to form monogamous mating pairs?
spider monkeys do
How does biodiversity change with latitude and area?
Biodiversity generally decreases with increasing latitude, as the number of species tends to decline towards the poles. In contrast, biodiversity increases with larger areas as larger habitats can support more diverse ecosystems and species. This is due to the availability of more niches and resources in larger areas.
Why was it a revolution?
Revolution is a turning, a change. Revolution tends to imply a change of government by force.
When load on a normally excited synchronous motor is increased its power factor tends to what?
approach unit
Do brown trout and the starfish belong to the same species?
No. And one tends to doubt the sincerity of such a question.
Why does correlation happen?
Correlation occurs when two variables are related or co-vary in a systematic way. This means that as one variable changes, the other variable tends to change in a particular direction. Correlation can happen due to a direct cause-and-effect relationship or because both variables are influenced by a common third factor.
A triangle with a vertex at A(4 -8) is dilated so that A' has coordinates (-3 6). The scale factor used was?
It depends where the centre of enlargement (dilation) was; it can be any value.As all you have given us is the change in the coordinate of the A vertex, so all we can conclude is that the centre of enlargement is somewhere along the line y + 2x = 0.Examples:If the centre is at (3, -6) then the scale factor is -6If the centre is at (0.5, -1) then the scale factor is -1If the centre is at (0, 0) then the scale factor is -3/4If the centre is at (-3, 6) then the scale factor is 0If the centre is at (-4, 8) then the scale factor is 1/8If the centre is at (-10, 20) then the scale factor is 1/2If the centre is at (11, -22) then the scale factor is 2If the centre is at (1.4, -2.8) then the scale factor is 6(As the centre tends towards ±∞ the scale factor tends towards 1 [from below towards -∞, from above towards +∞].)
Can soybeans cause allergy in rabbits?
Yes. Soy is not easily digested by rabbits and tends to cause blockage in their intestines. It should be avoided.
Stress tends to manifest itself in change?
