Answer:
D. all of the above
Explanation:
Biome refers to a large and relatively distinct terrestrial region having similar climatic conditions regardless of where it occurs on Earth. The characteristic climatic conditions (temperature and precipitation being the most important ones) and soil type of each biome type determine the type of plant species found there. Therefore, each biome is characterized by specific flora.
For example, a desert biome is a temperate or tropical biome characterized by a lack of precipitation, seasonal variations in temperature and poor soil type with low organic matter that limits plant growth. Desert biomes have only the plant species that can survive these harsh conditions.
Answer:
A hammerhead shark that gave birth in a Nebraska aquarium reproduced without mating, a genetic analysis shows. This form of asexual reproduction, called parthenogenesis, has been found in other vertebrate species, including some snakes and lizards. But this is the first time it has been documented in a shark.
Principle of Dominance was given by Sir Gregor Johann Mendel.
<h3><u>Explanation:</u></h3>
Principle of Dominance was given by Sir Gregor Johann Mendel as a conclusion of the monohybrid cross between the different characteristic pea plants. It says that in an organism which is heterozygous for a particular character, only the dominant trait is able to express as a phenotype, not the recessive one. In other words, the recessive allele is completely masked by the presence of the dominant allele. This leads to same phenotype of a homozygous dominant organism and a heterozygous organism.
To test the organism about its heterozygosity, the organism is led through a test cross where the organism is crossed with a recessive organism. If the F1 offsprings are all dominant, then the organism is homozygous dominant, and if the F1 offsprings are of half dominant and half recessive phenotype, then the organism is heterozygous.
