PLS SOMEONE DRAW ME Punnett square FOR THIS ASAP,


In mice, brown coat is dominant to black coat. If a pure breeding brown mouse is mated to a pure breeding black coated mouse, all of the offspring are brown. Fill in the Punnett square below to show this cross.

Answers

Answer 1

Answer:

Punnett square drawn below:

Explanation:

Sorry if it's messy. Since brown coat is dominant to black coat, that would mean that the genotype for brown is either Aa or AA. Since it says it's a pure breeding brown mouse and that all of the offspring are brown, that means that the genotype for the pure breeding brown mouse is AA. As for the black coated mouse, black is reccessive, meaning the genotype would be aa. So... AA x aa = 100% Aa

The fossil presence of anatomically modern humans in ________ demonstrates that our ancestors were capable of substantial water crossings by 40,000 years ago.

Answers

Answer:

The correct answer is - Africa.

Explanation:

Scientists found the fossils of modern humans called Mota an ancient man who lived around 40000 to 45000 years ago in Ethiopia. It was the first DNA isolated from Africa.

This DNA sample says that the Europeans have 6% of the DNA of this modern human, which suggests that there was substantial migration of people into Africa from Europe and the middle east by water crossings.

What are possible effects warming the atmosphere?​

To create a knockout mouse, after introducing to ES cells a DNA construct in which a specific gene is mutagenized by the insertion of a drug resistance marker, the cells, that have incorporated the transgene by homologous recombination grow in the presence of the drug and these are injected into a host blastocyst. The correct option is A.

What is biological marker?

A biomarker is an objective measure of what is going on in a cell or organism at any given time. Biomarkers can serve as health-related early warning systems.

To create knockout mice, researchers insert artificial DNA into the chromosomes contained in the nuclei of ES cells using one of two methods.

Both methods are performed in vitro, that is, on cultured cells grown in a laboratory setting.

After introducing a DNA construct into ES cells that mutagenizes a specific gene by inserting a drug resistance marker, the cells that have incorporated the transgene via homologous recombination grow in the presence of the drug and are injected into a host blastocyst.

Where is the best place to live to avoid the problems caused by
climate change and why?

Answers

in the us- Anchorage, Alaska because the natural environment is far more resilient to a major weather event than a large city setting and can better adapt to changing sea levels or temperatures. With less people and man-made infrastructure, there are fewer things to be maintained in the area, allowing the wilderness to react naturally to changing weather patterns and climate.
outside the us- Denmark because the country has continued to make strides forward, in air quality in particular. On the previous report, 78.8% of the population was exposed to unsafe levels of fine particle air pollution; now, the figure has dropped to 56.9%. Denmark tops the list of countries doing the most to protect the environment, among them having at least half its energy consumption come from renewables by 2030 and to be independent of fossil fuels by 2050.

a mass extinctions is

Answers

Answer:

Mass extinction is when biodiversity or species in a living habitat decreases to about three-fourths of its original number or to none. Such an event is identified by a sharp change in the diversity and abundance of multicellular organisms. It occurs when the rate of extinction increases with respect to the rate of speciation. Mass extinctions are usually associated with organisms that are macroscopic rather than microscopic. Examples of mass extinctions are Permian extinction of marine species, and Cretaceous extinction of various species, including dinosaurs.

What happens to a population when its size is equal to the carrying capacity?
a. Its size fluctuates wildly.
b. It increases in size.
c. Its size stays steady.
d. It decreases in size.

Answers

Answer:

C

Explanation:

When a population reachs its carrying capacity it will slow down and become steady due to the population reaching its limit on food, water, etc. and they can only feed so many.

When population size is equal to the carrying capacity then "Its size stays steady".

What is population ?

A population means the total number of individuals who cohabit in a certain area.

What is steady-state?

A biofilm that exhibits no net growth or degradation over time is usually referred to as a steady-state biofilm.

A population might slow down and stabilize once it reaches it's own carrying capacity since it will no longer be able to consume as much food, water, and other resources.
