How did experiments with mice contribute to our understanding of animal development?
Answers
Mice are used as the model species to learn different behavior of animal, physiological activities and doing experiment on mice will give us the knowledge to learn much better when there’s more mice rather than being alone.
Why Do We Experiment on Mice?Choosing mice as model organism for experiments makes a sense for more imaginative than scientific, these are small, don't need a lot of space, don't cause much damage when it is provoked, safe to do experiment on mice in lab.
It can be easily modified genetically which means scientists can manipulate any gene on any chromosome at any time, so that certain genes can be modified into inactive or turned off.
The scientist can manipulated mice and the process is called as knockout mice and they are a boon to researchers who are attempting to study how a certain genes can cause diseases.

Assess the consequences of exponential population
growth of any population.
Answers
The consequences of exponential population growth of any population is that the supplies could someday run out, birth rates might increase or decrease, and it might reach its carrying capacity.
Exponential Population Growth- Exponential growth happens if a population's per capita growth rate is constant, regardless of population size, leading the population to increase dramatically as the population rises.
Birth Rate- The proportion of live births to 1,000 people in the general population in a given year.
Carrying Capacity- The maximum number of humans that a particular kind of animal or plant can sustainably support. The smallest number of a specific species that the environment can tolerate. The usual number of individuals of a certain species that the habitat can support.

What is the circumference of a circle
with a radius of 28 m?
Answers
Considering the definition of circumference of a circle, the circumference of a circle with a radius of 28 m is 175.93 m.
Definition of circle and circumferenceA circumference is a flat, closed, curved line whose points are the same distance from an interior point called the center.
The circle is the surface of the plane bounded by the circumference. That is, it is formed by all the points of the circumference and all the points of the plane inside it.
Definition of circumference of a circleSo, the circumference of a circle defines the length of the circle's outline. The circumference is also called the perimeter of the circle, because it is a measure of the limits of the circle.
That is, the circumference of a circle is the distance around the circle, also called the perimeter of the circle.
The expression to calculate the circumference of a circle "C" can be found by multiplying the number pi by the diameter of the circle "d":
C= π×d
The circumference of a circle can also be calculated using the length of the radius, considering the radius is half the diameter (or what is the same, the diameter is twice the radius):
C= π×2×r
Circumference of a circle in this caseIn this case, you know the circumference of a circle has a radius of 28 m.
Replacing in the definition of circumference of a circle:
C= π×2×28 m
Solving:
C= 175.93 m
Finally, the circumference of a circle with a radius of 28 m is 175.93 m.

What tells you the size of the nucleus
Answers
Numerous structural elements of the nucleus, such as the nuclear envelope and DNA, regulate the size and shape of the nucleus.
One of the most noticeable features of a eukaryotic cell is its spherical nucleus, which normally makes up 10% of the cell's volume (refer the picture attached below).The nucleus of mammalian cells has an average diameter of about 6 micrometres.Lamins, intermediate filament proteins, are the proteins that make up the nuclear lamina. By supporting the nuclear envelope, they guarantee that the nucleus' general shape and structure are preserved.It makes sense that DNA may have an impact on nuclear volume as the size of the nucleus may be directly correlated with the quantity of DNA it contains and the degree to which that DNA is compacted.Hence, numerous structural elements of the nucleus, such as the nuclear envelope and DNA, regulate the size and shape of the nucleus.

9. A flowering plant species grows on the mainland near the coast. One summer, a tropical storm blows seeds from this population several hundred miles out to sea. Some of the seeds land on an island, where they form a new population. Describe two ways that speciation could occur in this situation. Include the concepts of genetic drift, gene pool, reproductive isolation, and selection in your description.
Answers
Allopatric or peripatric speciation are the two types of speciation that might take place in this circumstance.
Allopatric vs peripatric speciation :Physical barriers prevent members of the groups from interbreeding, just like in allopatric speciation. Peripatric speciation, as opposed to allopatric speciation, is characterized by a large size disparity between the two groups.
What is the difference between peripatric and parapatric?The two diverging species still interact geographically during parapatric speciation, but there is selection against genetic exchange because of the disadvantage of heterozygotes. Because there is no contact between diverging populations during peripatric speciation, it is different from parapatric speciation.

cite two results of water’s high heat capacity that are essential for warm blooded animals ( endotherms ) ability to maintain thermal homeostasis
Answers
Answer:
People, polar bears, penguins, and prairie dogs, like most other birds and mammals, are endotherms. Iguanas and rattlesnakes, like most other reptiles—along with most fishes, amphibians, and invertebrates—are ectotherms.
Endotherms generate most of the heat they need internally. When it's cold out, they increase metabolic heat production to keep their body temperature constant. Because of this, the internal body temperature of an endotherm is more or less independent of the temperature of the environment. What is metabolism?

Two test tubes labeled A and B
We set up another experiment in which we added the following enzymes:
Test Tube A = cellulase and Test Tube B = amylase. When the substrate
from the enzyme lab is added what would you expect to see happen in
each tube?
Answers
An enzyme-catalyzed reaction initially progresses at a faster pace as substrate concentration rises. This rise in rate of a reaction levels off as the substrate saturates the enzyme molecules.
An enzyme's concentration increases along with the speed of an enzyme-catalyzed process. The breakdown of the polysaccharide starch (amylose) into the disaccharide maltose is catalyzed by the enzyme amylase. Although it is easily abundant in saliva, obtaining high amounts might be uncomfortable. It is found throughout plant tissues, but it is most prevalent in seed, where that might play a role in starting the conversion of starch that has been stored into the much-needed glucose in enzyme-catalyzed process. The most prevalent organic polymer on earth is cellulose, a polysaccharide made up of a linear chain of 1,4-linked d-glucose subunits with such a degree of polymerization ranging from few hundreds to over ten thousand. An enzyme-catalyzed process is created when an enzyme binds to its substrate. This complex provides certain ions or chemicals groups that really establish chemical bond with molecule as a crucial stage of the reaction process, lowering the energy of activation and promoting its quick progression.

7. Heat tolerance in flies is a heritable trait. The variation in heat tolerance across a population of flies can be measured by subjecting groups of 100 flies to different temperatures and measuring the percentage of flies that survive. The following graph shows the distribution of heat tolerance across one species of fly living in hot desert regions of Africa. Predict what will happen to the size of this population and its allele frequency if a massive heat wave descends on the area in the future, bringing daily temperatures to 42°C and lasting several months of time.
Answers
All flies that can't tolerate 42°F will die. Only high-temperature-tolerant alleles are handed down.
'This is further explained below.
What are alleles?Generally, One of two or more variants of a DNA sequence (either a single base or a segment of bases) at a specific position within the genome is known as an allele.
In conclusion, All of the flies in the population that are unable to withstand temperatures higher than 42 degrees Fahrenheit will perish. Only those alleles that are responsible for high-temperature tolerance will be passed down to subsequent generations.
The populace will get used to the heat.
The survival curve will begin to ascend after a few months have passed.
