Answer:
Explanation:
You have to assume that this is complete dominance and one of these traits is dominant. To get the recessive characteristic, the alleles (versions of the gene) both have to be recessive (both lower case). But to have the dominant phenotype, either both alleles could be dominant (upper case) or you could have one of each (heterozygous, where you have one upper case and one lower case).
So there are two possibilities for genotype of the cat with the dominant characteristic. Since you don't know (yet) which it is, just use the letters "E" and "e" and set up the two possible Punnett squares:
......|...e...|...e...|
..E..|..Ee..|..Ee..|
..E..|..Ee..|..Ee..|
......|...e...|...e...|
..E..|..Ee..|..Ee..|
..e...|..ee..|..ee..|
In the first Punnett square, all the offspring have the same genotype, so they would also have the same phenotype. In the second square, you have offspring with two genotypes, one of which would produce the dominant phenotype (Ee) and one of which would produce the recessive phenotype (ee). Since your problem states that all the offspring have the same phenotype, the correct Punnett square is the first one where all the kittens are heterozygous (Ee). Since the dominant allele (E) masks the recessive allele (e), then curly ears has to be the dominant trait, since that's the phenotype of all the kittens.
Answer:
The correct answer would be option D.
In any food web, the inorganic carbon from the atmosphere is incorporated into the organic matter by the process of photosynthesis.
Autotrophs perform photosynthesis and fix carbon obtained from carbon dioxide into the glucose or organic matter with the help of chlorophyll and in the presence of sunlight.
6 CO₂ + 6 H₂O → C₆H₁₂O₆ + 6 O₂
Answer:

Explanation:
1. Water is abioitic and is needed by every living organism Soil is abioitic and is needed by plants Trees and other plants release water vapor from their leaves (a process called transpiration) that create humidity (which in turn influences how much rain falls in an area) The climate in an area influences the special adaptations that plants and animals have. For example: warm fur coats and thick layers of fat to keep warm in cold climates, animals in dry, hot climates (desert) have large ears to release heat and cool down. Biotic factors also influence abiotic factors. Animals produce waste (go to the bathroom) which in turn will become nutrients in the soil.
2. decrease heat will affect biotic factors, like animals, warmth.

Ears
¿Qué es el oído y qué hace?
El oído consta de tres partes diferentes, que funcionan conjuntamente para captar sonidos y transmitírselos al cerebro: el oído externo, el oído medio y el oído interno.
El oído externo
El oído externo está formado por el pabellón auditivo (también conocido como "pabellón auricular" o "pabellón de la oreja") y el conducto auditivo. Los pabellones auditivos son las partes visibles que tenemos a ambos lados de la cabeza y están compuestos por cartílago duro cubierto de piel. La principal función del pabellón auditivo consiste en captar sonidos y conducirlos hacia el conducto auditivo, que conecta con el oído medio. Las glándulas de la piel que recubren el interior del conducto auditivo fabrican cera o cerumen, que protege este conducto, eliminado la suciedad y ayudando a prevenir posibles infecciones.
El oído medio
El oído medio es una cavidad llena de aire que transforma las ondas sonoras en vibraciones y las transmite al oído interno. El oído medio está separado del externo por el tímpano (o membrana timpánica), una fina lámina de tejido que va de lado a lado del conducto auditivo y que está fuertemente tensada sobre él. Los sonidos golpean el tímpano, haciendo que se mueva.
