Cats can have a trait where their ear folds down, a breed called the “Scottish Fold,” displays this phenotype in most breedings The gene for folded ears is dominant (E) and the gene for straight ears (e) is recessive.
Write the three genotypes that are possible (choose your letters) and describe their phenotypes. Remember, genotypes have two letters and the phenotype describes what the cat looks like (folded or straight).
Answers
Answer:
Ee = Folded ears, ee = straight ears, and EE = Folded ears
Explanation:
As long as a dominant allele is present, it will always appear in the phenotype. However, if no dominant alleles are present, the recessive allele appears. Hope this helps :)

Explanation:
How are the Hawaiian honeycreepers an example of adaptive radiation?
There were a large variety of honeycreepers that first inhabited the island. They found many different niches, so they were all able to survive.
The honeycreepers that first inhabited the island were able to adapt as the island changed, so that population of birds was able to survive.
There was a diversification of honeycreepers (each with different beak shapes) to help fill various ecological niches.
Answers
Answer: In adaptive radiation, many different species evolve from a single ancestor species. Each new species evolves to exploit a different niche, such as food source. In the example above, Hawaiian honeycreepers evolved a range of bill forms in response to available food sources on the Hawaiian archipelago. The honeycreepers dispersed from one founder species, and evolved in response to natural selection based on different food sources in their isolated habitats provided by water. Seed-eating birds evolved thick, short beaks.
How does bios mass energy work? what is the political obstacle keeping biomass from being used ?
Answers
a) Biomass is renewable organic material that comes from plants and animals. ... Biomass contains stored chemical energy from the sun. Plants produce biomass through photosynthesis. Biomass can be burned directly for heat or converted to renewable liquid and gaseous fuels through various processes
b) Obstacle keeping biomass from being used ?

GC, CG, TA, AT, TA, GC, CG, AT, CG, GC, TA, CG, GC, CG, and AT. What is a DNA molecule?A DNA molecule may be defined as a molecule that comprises the biological instructions that construct each species unique in terms of genetic sequences.
The nucleotide bases are always bound to each other in a complementary form, i.e. A is bonded to T with the help of two hydrogen bonds, while C is bonded to G with the help of three hydrogen bonds.
Apart from this, according to Chargaff's rule, the amount of adenine is always equal to the amount of thymine, while the amount of guanine is always equal to the amount of cytosine.
Therefore, it is well described above.

Plants lose water from their above ground surfaces in the process of transpiration. Most of this water is lost from stomata, microscopic openings in the leaves. Excess water loss can have a negative effect on the growth, development, and reproduction of a plant. Severe water loss can be fatal. Environmental factors have a major impact on the rate of plant transpiration. text... The curve below illustrates the rate of transpiration related to the percent of open stomata on the leaf of a particular plant. Explain why the curve levels off with increasing percentage of open stomata per area of the leaf.

Answer:
E
Explanation:
thanks again for your help and support you in whatever way you can get a good night's sleep and I will talk to you later I
The curve level off with an increasing percentage of open stomata per area of the leaf because the population decreases because of death. The unaffected plant species gain resources.
What is transpiration?Plant roots absorb a considerable amount of water from the soil. This water travels to various parts of the plant via sap ascending. The entire amount of water absorbed by the plant exceeds its requirement.
Only a fraction of this water from vapor is absorbed by plant aerial parts such as (stem, leaves, buds, and flowers), which account for around 95% of total absorbed water. This is known as transpiration.
Therefore, because the population reduces due to death, the curve flattens out with an increasing percentage of open stomata per area of the leaf. Plant species that are not harmed gain resources.

What forms in the sky when the air temperature is the same as the dew point Temperature? (Show steps)
Answers
Answer:
Cloud
Explanation:
Water vapor is not visible unless it condenses to become a cloud. Water vapor condenses around a nucleus, such as dust, smoke, or a salt crystal. This forms a tiny liquid droplet. Billions of these water droplets together make a cloud.
Explanation:
High in the sky where the air cools to the dew point, evaporated moisture becomes clouds. At ground level, it's fog when a layer of mist forms at a point just off the ground surface, and it's the same process.

it occurs in two stages: transcription and translation
explanation:
transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. it includes three steps: initiation, elongation, and termination. after the mRNA is processed, it carries the instructions to a ribosome in the cytoplasm.translation occurs at the ribosome, which consists of rRNA and proteins. in translation, the instructions in mRNA are read, and tRNA brings the correct sequence of amino acids to the ribosome. then, rRNA helps bonds form between the amino acids, producing a polypeptide chain.explain why variagated plants accumulate less food than non variegated plants under similar conditions

Describe how people change their body shapes (not their clothes) when they are very hot and when they are very cold. Use your knowledge of surface area : volume ratios to explain why we do this.
Answers
Answer:
This quesiton is unclear
Explanation:
The body has negtive feedback loops that either vasoconstrict (preserving heat by lessening the surface area of blood vessels so they are exposed to less cold and release less heat) and vasodilation, where blood vessels are expanded and have higher surface areas so the body hopes to lose more heat to cool down.
If this is purely body language (like going into a fetal position when its cold: to lessen the surface area exposed to the cold temperature and lose less heat, imagine an ice cube vs. a long thin tube of ice with equal volume, the cube will last longer. Similarly our bodies would spread out to release more heat (unless there was sun) this is to expose the most surface area, allowing our body to release the most heat. Note: this is pretty insignificant change, and in extreme temperatures will likely not help, but it does contribute.
