Answer:
In studying the origin of the universe, one of the primary unanswered questions is <u>what came before the big bang.</u>
Explanation:
The big bang theory can be described as a theory which scientists have proposed to explain how the universe came into existence. This theory predicts how the extremely hot temperatures and dense atmosphere might have given rise to the stars and the galaxies.
Scientists have no idea what happened before the big bang theory. Some scientists predict that there might be another universe which collapsed before the big bang theory. While other scientists claim that there was nothing before the big bang.
The answer is D) 1/2.
If each allele confers a unit of color darkness, then only genotypes S2S3 and S1S4 will have 5 units of color darkness because in genotype S2S3 S2 will have 2 units, and S3 will have 3 units, which is 5 units in total. The similar math is for <span>genotypes S1S4.
</span>
Now, let's cross S1S3 and S2S4:
Parents: S1S3 x S2S4
Offspring: S1S2 S1S4 S2S3 S3S4
The offspring with genotype S1S2 will have 3 units of color darkness. The offspring with genotype S1S4 will have 5 units, as well as the offspring with genotype S2S3. The <span>offspring with genotype S3S4 will have 7 units.
It can be assumed that only 2 genotypes out of 4 will have 5 units:
2/4 = 1/2.</span>
The most likely answer is
D)Decreased number of fish species who use the estuaries.
The Japanese model for shrimp farming in estuaries basically involves converting estuary areas into shrimp farms, isolating these areas and dedicating them solely to the farming of shrimp. This excludes other fish species from areas that were previously the environment in which they lived.
Answer: The correct answer is- C) vacuole.
Large central Vacuole is a specialized fluid filled organelle, present only in plant cell. It is primarily involved in providing support and shape to the plant cell by maintaining the turgor pressure ( a hydrostatic force that is produced due to the cell contents against the inner side of the cell wall). The central vacuole stores water ( that flows through osmosis) and maintains turgor pressure in a plant cell.
Turgor pressure provides mechanical support and helps in the growth and development of plant.
Answer:
The term "phenotype" refers to the observable physical properties of an organism; these include the organism's appearance, development, and behavior. An organism's phenotype is determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes.
Explanation:
The physical appearance of an organism as distinguished from its genetic makeup.
