explain how natural selecin oacting on allele frequencies of a gene that controls body coloraiton can result in populations of 3 different species
Answer:
Answer below
Explanation:
Well when natural selection occurs, genes that don't benefit the speicies, or more accurately, harm it by ruining camoflague. Natural selection can result in one creature evolving into 3 different species when those creatures get put into different environments that promote genetic mutations that help them survive. After a long while of genetic mutations coming and going to adapt to their environment, those three members of the species are no longer the same species because they've all adapted to different environments.

What is the area in the mutcd that is used to channel the motorist to the open travel lane?.
The area that in the MUTCD that is used to channel motorists to the open Trav Lane is the work space.
What is a work space?The work space is a segment of the highway which is very near or closer to road users and it is set aside for workers, equipment, and material, and a vehicle used upstream for travel lane. Work spaces are separated from road users by channeling it with some devices to exclude vehicles and pedestrians using a temporary barricade.
Therefore, area that in the MUTCD that is used to channel motorists to the open Trav Lane is the work space.

Why do animals such as sparrows and deer experience less loss of genetic diversity due to fragmentation than for instance mice or salamanders
Answer:
Severe fragmentation is a typical fate of native remnant habitats in cities, and urban wildlife with limited dispersal ability are predicted to lose genetic variation in isolated urban patches. However, little information exists on the characteristics of urban green spaces required to conserve genetic variation. In this study, we examine whether isolation in New York City (NYC) parks results in genetic bottlenecks in white-footed mice (Peromyscus leucopus), and test the hypotheses that park size and time since isolation are associated with genetic variability using nonlinear regression and information-theoretic model selection. White-footed mice have previously been documented to exhibit male-biased dispersal, which may create disparities in genetic variation between males and females in urban parks. We use genotypes of 18 neutral microsatellite data and four different statistical tests to assess this prediction.
The logistic growth model predicts that the growth rate of a population will decrease as the population size approaches the environment’s carrying capacity. Under what circumstances would you predict that a population would increase in size over and above its carrying capacity?.
In logistic growth, a population's per capita growth rate gets less and less as population size approaches a maximum charged by limited resources in the background , known as the carrying capacity.
The logistic population boost occurs when the growth rate of drops as the population reaches the carrying capacity.
What is logistic population growth?In logistic growth, population growth declines as resources become low, and it fells off when the carrying capacity of the atmosphere is reached. The logistic growth curve is S-shaped.
Thus, The logistic population boost occurs when the growth rate of drops as the population reaches the carrying capacity.

How many chromosomes are present in the cell before the start of meiosis?.
Answer: 46
Explanation: 46 chromosomes are present in the cell before the start of meiosis.
The number of chromosomes that are present in the cell before the start of meiosis is 46. Because the total number of chromosomes in a human cell is 46.
What are chromosomes?Chromosomes are the thread-like structure present in pairs in all organisms. They are present inside the nucleus, and contain genes and DNA in them, and are responsible for the traits of an organism.
Meiosis is a process completed in two stages, and each contains four phases. It occurs in the germ cells, divides the cell into four cells, and reduces the number of chromosomes.
The number of chromosomes in humans is 46, 23 in pairs. Before meiosis, the number of chromosomes will be 46 after Meiosis the number reduces.
Thus, there are 46 chromosomes in the cell prior to the onset of meiosis.
