Answer:
I did this for my test and had them correct
1. strawberries
2. fish
Explanation:
The most recent and arguably best-known, the Cretaceous–Paleogene extinction event, which occurred approximately 66 Ma (million years ago), was a large-scale mass extinction of animal and plant species in a geologically short period of time.
The correct option is (D) The ecological footprint of the United States is large because per capita resource use is high.
<h3>
What is ecological footprint?</h3>
- The Global Footprint Network advocates using the ecological footprint to determine how much nature is required to support a certain population or economy.
- The ecological footprint accounting system tracks how much nature is being used and produced.The Ecological Footprint calculates the total productive areas for which a population, a person, or a product competes on the demand side.
- It evaluates the ecological resources required by a specific population or product in order to produce the natural resources it consumes, as well as to absorb its waste, particularly carbon emissions.
- The biocapacity of a city, state, or country, on the supply side, measures how productive its ecological resources are (including cropland, grazing land, forest land, fishing grounds, and built-up land).
- These regions can also be used to absorb the garbage we produce, particularly our carbon emissions from burning fossil fuels, especially if they are left unharvested.

Answer:
1) RR x rr
2) Shown below
3) 100% Rr with red eyes
4) Punnett square shown (Rr x Rr)
5) 25% of the offspring are h0m0zygous dominant with red eyes (RR), 50% are heterozygous with red eyes (Rr), and 25% are h0m0zygous with brown eyes (rr)
Explanation:
Let's say the allele for red eyes is R and the allele for brown eyes is r.
1. A cross between a h0m0zygous dominant (two copies of the dominant allele, R) and h0m0zygous recessive (two copies of the recessive allele, r) is: RR x rr
2. R R
r <em>Rr Rr</em>
r <em>Rr Rr</em>
<em />
The F1 generation is shown in the Punnett square above.
3. The F1 generation are 100% Rr. They are heterozygous. Since red (R) is dominant, the rats all have red eyes
4. A cross between the F1 generation (Rr x Rr) gives the F2 generation
R r
R <em>RR Rr</em>
r <em>Rr rr</em>
<em />
5. 25% of the offspring are h0m0zygous dominant with red eyes (RR), 50% are heterozygous with red eyes (Rr), and 25% are h0m0zygous with brown eyes (rr)
