3. Deer mice (adapted from exercise 15.38, 4t ed Baldi & Moore)
3 points
Deer mice are small rodents native to North America with body lengths (excluding tails) that are
known to vary approximately Normally, with a mean ц = 86 mm and a standard deviation o = 8 mm.
A researcher wants to study the effect of habitat food source degradation on deer mouse body
length.
First, however, you want to figure out how many deer mice you would need for successful inference
about the mean u in the population of all deer mice that would ever experience habitat degradation.
What sample size would be needed to estimate y within +/- 2.5 mm with 95% confidence?
I got 62, but the answer is 40, and I can’t figure out what I am doing wrong. Please advise
Answers
It's possible that the answer provided is using a different level of confidence than the one specified in the question (95% confidence).
Using the same formula as before, we have:
n = (Z^2 * o^2) / E^2
Substituting the given values, we get:
n = (1.96^2 * 8^2) / 2.5^2 = 61.92
Rounding up to the nearest whole number, we need a sample size of 62 deer mice to estimate the population mean within +/- 2.5 mm with 95% confidence, assuming that the population standard deviation remains the same under habitat food source degradation.
Therefore, it seems like the correct answer should be 62, not 40.

How do the functions of the skeletal and muscular system differ?
A.
Muscles send signals to the body, and bones are responsible for movement.
B.
Bones provide structure and support to the body, while muscles move the bones.
C.
Bones send signals to the body, and muscles are responsible for movement.
D.
Muscles provide structure and support to the body, while bones move the muscles.
Answers
Answer:
The functions of the skeletal and muscular systems differ in that bones provide structure and support to the body, while muscles move the bones.
Explanation:
The skeletal and muscular systems have complementary functions, which is why they are sometimes referred to as the musculoskeletal system.
Bones are solid organs, made up of calcium, which are connected to each other through joints, which provide them with a certain range of mobility. The main functions of the bones are protection and body support.
Muscles are contractile organs that are attached to bones by tendons. The location and relationship of the muscle to the bones is what makes it possible for the bony skeleton to move. Muscle contraction and relaxation is what contributes to the different body movements.
The other options are not correct because:
The function of the bone is to support, and the function of the muscle is to produce movement. Bones and muscles are not the ones that send the signals for body movement to occur.Answer:
B. Bones provide structure and support to the body, while muscles move the bones.

(HELP FAST) A slanting, horizontal line is shown. On the extreme left, there is a label that says Common Ancestor. Along the slanting, horizontal line there are five dots labeled from left to right as: 1, 2, 3, 4, and 5. There is one vertical line between each of the consecutive five dots. The lines are labeled from left to right as Perch, Frog, Pigeon, Rats, and Human. A text box below the branching tree diagram is labeled Derived Shared Characteristics. In the box it says from left to right Terrestrial during all stages, Jaws, Walking on two legs, Mammary glands and hair, and Four limbs.
Look at the possible derived shared characteristics, shown in the text box. Think about where these should be placed along the branching tree diagram. Where in the branching tree would you most likely write "lives on land during all life stages"? Explain your answer.
Answers
"The derived shared characteristic 'Terrestrial during all stages' should be placed at the base of the tree diagram."
SupThe characteristic "Terrestrial during all stages" is a shared characteristic among all five species being compared in the branching tree diagram. This means that it is a characteristic that all of these species have in common, and therefore it is likely that it was present in their common ancestor.
Since the base of the tree represents the common ancestor of the species being compared, it makes sense to place this characteristic at the base of the tree. This also helps to show that this characteristic is a defining trait of the group of species being compared and that it has been present in their lineage since their common ancestor.

Forested floodplain wetlands benefit from periodic flooding from rivers. When floodwaters spill into the wetland, they bring water and nutrients and leave both behind. But humans have often cut off floodplains from rivers by building roads, levees, berms, etc. Think about what would happen if a river could no longer flood into these areas. How would the resulting increased amount of water and nutrients in the river affect soils, hydrology, and life downstream?
Answers
The absence of flooding from rivers into forested floodplain wetlands would lead to adverse effects on soils, hydrology, and the overall biodiversity downstream, emphasizing the importance of maintaining the natural connection between rivers and floodplains for the health and functioning of these ecosystems.
If a river can no longer flood into forested floodplain wetlands due to human interventions, it would have significant consequences for the downstream areas in terms of soils, hydrology, and life.Without periodic flooding, the increased amount of water and nutrients in the river would not be able to disperse and be deposited in the floodplain wetlands. As a result, downstream soils would experience a decrease in nutrient inputs, leading to decreased fertility and altered composition. The absence of regular flooding would disrupt the natural hydrological cycle, reducing the recharge of groundwater and altering the flow patterns in the river system. This could result in decreased water availability, increased erosion, and changes in the overall ecosystem dynamics downstream.The disruption of nutrient flows and hydrological patterns would also have a significant impact on the life forms downstream. Aquatic plants, fish, and other organisms that depend on floodplain wetlands for breeding, feeding, and shelter would face habitat loss and reduced food availability. This, in turn, could disrupt the food chain and impact the abundance and diversity of aquatic and terrestrial species in the downstream areas.The absence of flooding from rivers into forested floodplain wetlands would lead to adverse effects on soils, hydrology, and the overall biodiversity downstream, emphasizing the importance of maintaining the natural connection between rivers and floodplains for the health and functioning of these ecosystems.For more such questions on flooding

If the DNA sequence is CCAATTGA, what is the compliment?
Answers
GGTTAACT is the complement of DNA sequence CCAATTGA.
What is a complement sequence of DNA?A sequence of bases in a nucleic acid called a complementary sequence can be used to match base pairs to create a double-stranded structure. For instance, G-T-A-C is the complementary sequence to C-A-T-G, where each letter represents a different DNA nucleotide.
Every DNA sequence has a counterpart sequence running in parallel since DNA has two strands. Adenine (A) is always coupled with Thymine (T) in the complementary sequence, while Cytosine (C) is always paired with Guanine (G).
Natural complementary DNA plays a crucial role in the production of new DNA copies and has emerged as a key experimental tool. The two strands of DNA are unraveled from one another during replication. Each strand is replicated twice, one by a DNA polymerase molecule that runs the length of each strand.

15. Which sequence correctly represents the
arrangement of structures containing genetic
material, from the largest to the smallest size?
Answers
Answer:
The correct sequence that represents the arrangement of structures containing genetic material, from the largest to the smallest size, is:
Chromosomes: These are the largest structures that contain genetic material. Chromosomes are made up of DNA and proteins and are visible under a microscope during cell division.
Genes: These are segments of DNA that contain instructions for making proteins. Genes are located on chromosomes and are the basic unit of inheritance.
DNA: This is the genetic material that carries the instructions for the development and function of all living organisms. DNA is a long, double-stranded molecule made up of nucleotides.
Nucleotides: These are the building blocks of DNA. Each nucleotide is made up of a sugar molecule, a phosphate group, and a nitrogenous base. There are four types of nitrogenous bases: adenine, thymine, cytosine, and guanine.
Base pairs: These are the complementary nitrogenous bases that pair up to form the rungs of the DNA ladder. Adenine pairs with thymine, and cytosine pairs with guanine. The sequence of base pairs determines the genetic code.
