There is no solid scientific evidence that humans have been cloned.
Answer:
Perishable foods should never be thawed on the counter or in hot water and must not be left at room temperature for more than two hours. There are safe ways to thaw food: in the refrigerator, in cold water, and in the microwave.
Explanation:
Answer:
Index fossils
Explanation:
The index fossils are the fossils that come in very handy for the geologists when it comes to identifying or dating rock samples or other fossils. The reason for this is that the index fossils have already been dated. They are fossils that are very commonly found, wide dispersed, are easy to be identified, and are limited to only a certain geological period. These characteristics make them an excellent indicator for the dating of the rock layers in which they are found, or the fossils found in the same layers with them, without conducting further examinations.
Answer:
Ecology refers to the scientific study of the associations between the organisms and the surroundings in which they thrive. Humans have always been witnessing and learning about the organisms and their surroundings around them. They have acquired many insights and deduced hypothesis on the basis of their observations.
This is the aspect of discovery in the branch of ecology. Identically, there is an experimental scenario associated with the ecology that has been developed recently. This comprises formulating a hypothesis first and then examining it in the field or in the lab. Therefore, ecology utilizes the fundamental scientific procedure of hypothesis formulation and then examining and validating by the observations and experiments.
In this case, the black body colour is the dominant one. The white dog is homozygous recessive.
As the cross between the black female 2 and the white male results in all black pups. This means that the all the offsprings are heterozygotes and the Female 1 is homozygous recessive having a BB phenotype (where B codes for dominant allele).
As the cross between the black female and the white male results in four white and three black pups. This means that the all the black offsprings are heterozygotes, and the white ones are homozygous recessive and the Female 2 have a dominant and 1 recessive gene, and is a hetrozygotezygous recessive having a Bb phenotype (where B codes for dominant allele and b codes for recessive allele).
