This might not help, but there are five fundamental factors that induce an allele frequency shift in a population, or a collection of interacting organisms of a same species, from one generation to the next. Mutation, genetic drift, gene flow, non-random mating, and natural selection are all examples of evolution.

Answers
Answer:
Fossils
Explanation:
By using fossils we can not only know that extinct animals once roamed the planet, but also get an estimate of when they did so. We can use fossils to pin down their location (which we can use to see what might have killed them, resource loss, climate change, human interaction, etc.), to see when they appeared and went extinct (thanks to rock layers and knowledge of geology), and even what may have been in their diets (based on location or.. well, other pieces of evidence, if you know what I mean.) Fossils also give you their size and shape which can help paleontologists determine the type of animal, ex. birdlike, reptile, mammal, etc.
The operational range of temperature in an incubator is
Answers
Explanation:
The operational range of temperature in an incubator is 99 ° to 102 ° F
The operational range of temperature in an incubator varies depending on the type of incubator and the application. However, a typical range is between 35 and 100 degrees Celsius (95 and 212 degrees Fahrenheit). The specific temperature range will be specified in the incubator's manual.
For example, a laboratory incubator used for growing bacteria or cells might have a temperature range of 35 to 55 degrees Celsius (95 to 131 degrees Fahrenheit). An incubator used for hatching chickens might have a temperature range of 37 to 40 degrees Celsius (99 to 104 degrees Fahrenheit).
It is important to note that the temperature range of an incubator should not be exceeded, as this could damage the incubator or the samples being incubated. It is also important to monitor the temperature regularly to ensure that it is within the desired range.

Among evolutionary mechanisms, there can be mentioned non-random matings (1 and 8) , mutations (3 and 6), genetic drift (2, 4 and 5), and genetic flow (7).
What are evolutionary mechanisms?These are different mechanisms that change allelic frequencies and genotypic frequencies conserning the expected ones if populations were under Hardy-Weinber equilibrium.
When these mechanisms are going on, populations evolve.

Removing a flower’s stigma would initially affect
Answers
Answer:
Pollination.
Explanation:
Removing a flower’s stigma would initially affect pollination.
Removing a flower’s stigma would initially affect pollination.
The stigma is found in the pollen-bearing part of the flower, which is called the “gynoecium”. The stigma’s primary purpose is to pull pollen grains out of the air using its sticky tip in order to reproduce.
If a flower does not have an anther or stigma, then the flower may be cross-pollinated. Cross-pollination occurs when pollen from one flower fertilizes the pollen of another flower. In other words, pollen from one plant fertilizes pollen from another plant.
When the stigma is taken off before pollination occurs, then the pollen grains do not collect in the receptive area of the flower.
