The Punnett square describes the potential offspring of a cross. What phenotypes will be shown by the offspring?
o A. All offspring will show the recessive phenotype for this trait.
B. All offspring will show the dominant phenotype for this trait.
C. Half of the offspring will show the dominant phenotype and half will show the recessive phenotype.
D. Three fourths of the offspring will show the dominant phenotype and one fourth will show the recessive phenotype.
Answers
Answer:
B. All offspring will show the dominant phenotype for this trait.
Explanation:
At least one dominant alelle will be present in all the offspring of the f1 generation, and since it is dominant, it will overshadow the recessive alleles.

5. The mechanism for evolution is natural selection. Traits become more or less
common in a population depending on whether they are beneficial or harmful.
An example of evolution by natural selection can be found in the deer mouse,
species Peromyscus maniculatus. In Nebraska this mouse is typically brown, but
after glaciers carried lighter sand over the darker soil in the Sand Hills, predators
could more easily spot the dark mice. Natural selection favored the light mice,
and over time, the population became light colored. What was the environmental
change that resulted in a change in the deer mouse?
O A. The Ice Age
O B. Environment changed color
O C. Became colder
O D. No change
Answers
Answer: A
Explanation: the ice age posed a new chalenge to deer mice and on the ice the preadators could spot the darker deer mice better than the light deer mice.

WILL GIVE BRAINLISTTT!!! How can life and conditions on Earth be used as a model for life on other worlds?
Answers
Answer:
You can see the conditions of the other world, and see the composition of that world. This allows you to see what elements are abundant. Assuming there is water on that other planet, you can use the elements that are found there and see what organisms on earth are composed of those elements or use them.
Specifically, extremophiles (types of archaeabacteria) often exhibit characteristics that seem suitable for other planets. Using this, you can estimate what life on other planets have as characteristics, or even what they are made of.
Organisms with similar molecular makeups + organisms in areas with similar environmental pressures often exhibit anatomical + behavioral similarity. You can use this to model this.

A track athlete throws a 2kg discus into a field with a velocity of 21m/s. What is the momentum of the discus?
Answers
Answer:
Given :
Momentum of disc = 42 kg m/s
Velocity of disc = 21 m/s
To Find :
Mass of the disc.
Solution :
❖ Momentum is defined as the product of mass and it's velocity..
Mathematically, p = m × v
p denotes momentum
m denotes mass
v denoted velocity
➛ It is a vector quantity having both magnitude as well as direction.
➛ It can be positive, negative or zero.
➛ SI unit : kg m/s or N s
By substituting the given values;
➙ p = m × v
➙ 42 = m × 21
➙ m = 42/21
➙ m = 2 kg
∴ Mass of the object is 2 kg.

A research study looked at variations in snail populations in urban areas compared to natural ecosystems outside of the urban development. Urban areas tend to be be warmer, trapping more solar energy and reflecting less light back out of the atmosphere. The study found that brown snails were more commonly found in the natural ecosystem while yellow banded snails were found in the urban, developed areas. Which statement best describes the distribution in the phenotypes for the snails in this scenario?
A) The variations in the snail populations are random and unrelated to the locations.
B) The variation in the snail population is due to sexual reproduction of the snails in the urban development and asexual reproduction of the snails in the natural ecosystem.
C) The variation in the snail population is due to mutations while the distribution of colors in the population is due to genetic drift. The location of the colors is a random process.
D) The variation in the snail populations is due to mutations while the distribution of colors in the population is due to the changes in temperature in the two areas. Lighter colored snails survive with greater frequency in the warmer urban development.
Answers
Answer:
D) The variation in the snail populations is due to mutations while the distribution of colors in the population is due to the changes in temperature in the two areas. Lighter colored snails survive with greater frequency in the warmer urban development.
Explanation:
The distribution in the phenotypes for the snails in this scenario depends on the variations due to mutations as well as the change in temperature in the two areas.
What do you mean by Phenotypes?Phenotypes may be defined as the appearance or manifestation of desired characters. Phenotypes may also be known as traits.
The phenotypes of snail may get changes due to mutation which is caused by the high temperature in an urban area. UV light is considered a physical agent of mutation. Hence, the variation in the snail populations is due to mutations while the distribution of colors in the population is due to the changes in temperature in the two areas. Lighter-colored snails survive with greater frequency in the warmer urban development.
Therefore, The distribution in the phenotypes for the snails in this scenario depends on the variations due to mutations as well as the change in temperature in the two areas.
