Oksi-84 [34.3K]3 years ago
7 0

The answer is;  When the scientific claims are accepted when they are corroborated by scientific data. Experiments are set to collect data and make observations regarding the claims. Based on the outcome, the claims (which will be formulated as a hypothesis) will be accepted or rejected. When the experiment is replicated by different independent scientists and producing predictable results, then the claims become a scientific fact.

The generation of a knock-out organism generally requires all the following EXCEPT ________. The generation of a knock-out organ
PilotLPTM [1.2K]

Answer:

knowledge of the sequence product

Explanation:

A gene knockout is a technique used in molecular genetics to deactivate target genes in an organism in order to study their functions by reverse genetics (i.e., gene loss). Knockouts are generated by different methods including, for example, homologous recombination or site-specific nucleases (zinc-fingers, TALENS, CRISPR/Cas9). These techniques require to know a priori the sequence of each gene to be knocked out in order to target desired mutations. In the last years, the CRISPR/Cas9 tool has gained attention to knockout genes of interest because it is a genome editing system that can be easily used for deletion or insertion of bases.

What does the ocean do to the CO2 in the atmosphere?
LenaWriter [7]

Answer:

It absorbs.

Explanation:

The ocean absorbs carbon dioxide from the atmosphere wherever air meets water. Wind causes waves and turbulence, giving more opportunity for the water to absorb the carbon dioxide. Fish and other animals in the ocean breathe oxygen and give off carbon dioxide (CO2), just like land animals.

How did you determine the types of cell division for both phases depicted in your model? Explain your answer.
klasskru [66]

Answer:

Cell division is a process that makes our skin, tissues, muscles, sex cells etc. It is the building block of our body.

Explanation:

When parents cells ahs been divided into two or more than two daughter cells then it is called division of cells. The division of cells occur as a larger cell. When we talk about eukaryotic cells, these cells divided into two distinct types of the cells, the vegetative cells.

The daughter cells are the identical to the parents cells genetically. There are two types of division such as mitosis and meiosis. When parents cells divides in daughter cells and daughter cells divided further, this process called the cells cycle. The mitosis cell division occur interphase. Meiosis cell division occur in two phase meiosis I and meiosis II.
