Answer:
C. Plantae
Explanation:
1.Plants are multicellular
2.Consists organisms that are eukaryotic
3. Plants are autotrophic
Answer:
Yy, Yy, Yy, Yy
Yellow in color
Explanation:
Let the allele for green seed be represented by "y" and the allele for yellow seed be represented by "Y"
Given Yellow seed color is dominant over green.
Genotype of true breeding green seed parents will be yy
Genotype of true breeding yellow seed parents will be YY
F1 cross
Genotype of all the offspring is heterozygous "Yy"
Phenotype of all the offspring is yellow
Fish breathe by drawing water in their mouths and forcing it out of the body via a number of gill slits. The gill slits are rich in blood vessels, enabling the direct absorption of oxygen. While all fish have gills, some fish are also able to extract oxygen from the air via gulping.
Most fish have swim bladders that are permanently sealed, but other fish have swim bladders that can hold varying amounts of air. Salmon have open swim bladders, and they must gulp air at the surface to keep them full. Some fish, such as sharks, lack swim bladders entirely. This causes them to sink if they do not maintain forward motion.
Fish have fins that are adapted to their lifestyle. Some have evolved into long, barbed structures, suitable for defense. Other fish have fins suited for achieving great speed or for walking along the bottom of the ocean.
Answer:
D. partial pressure of oxygen
Explanation:
Partial pressure refers to the force applied by an individual gas per unit area in a mixture of gases which is measured in mm of Hg. The partial pressure determines the movement of the gas molecule in the system.
In the given scenario, the oxygen transport through the blood along with other gases like carbon dioxide and other minute concentration but the gaseous exchange between the lungs and the blood, between the blood and the tissues depends on the partial pressure of the oxygen. The oxygen moves from the higher pressure to lower pressure therefore partial pressure is the determining factor.
Thus, Option-D is correct.
