Answer:
Tien is correct with his answer that all the calico kittens are females.
The reason and the possible crosses to test the answer are given below
Explanation:
First of all, the coat color in cats is hugely decided by the sex-linked X chromosome in the female. This X chromosome found in cats makes cats exhibit codominant traits. The calico cat is a blend of black and yellow patches. To be considered calico, a cat must carry an allele for the black color and an allele for the yellow color.
The male is no heterozygotes and since the Y- chromosome in the male doesn't affect the result of the coat color in the offspring, there has to be a rare genetic disorder that will result in a calico kitten that is male.
The possible crosses to test his answer:
Cross 1:
If the black cat was the mother her genotype would be: Xb Xb
If the yellow cat was the father his genotype would be: Xy Y
The possible offspring from the cross would result in:
XbXy XbY XbY XbXy ( where XbXy are calico females and XbY are black males)
Cross 2:
If the yellow cat was the mother her genotype would be: Xy Xy
If the black cat was the father his genotype would be: Xb Y
The possible offspring from the cross would result in:
XyXb XyY XyXb XyY (where XbXy are calico females and XyY are the yellow males)
Which organisms release carbon dioxide as waste?
consumers only
consumers and decomposers
producers and decomposers
producers only
Answer: B
Explanation:
Consumers and decomposers are different types of organisms capable of releasing carbon dioxide as waste.
What are decomposers?Decomposers are organisms that obtain their food from dead organic material (dead plants, dead animals, etc).
Conversely, consumers are another classification of organisms which cannot synthesize their own food sources.In conclusion, consumers and decomposers are organisms capable of releasing carbon dioxide as waste.

If a radiometric age can be determined is there any use for a relative age? Why or why not?
Answer:
Radiometric dating calculates an age in years for geologic materials by measuring the presence of a short-life radioactive element, e.g., carbon-14, or a long-life radioactive element plus its decay product, e.g., potassium-14/argon-40. The term applies to all methods of age determination based on nuclear decay of naturally occurring radioactive isotopes. Bates and Jackson (1984)

Why are ion channels necessary to transport ions into or out of a cell?
Answer:
Ions carry electric charges and are not soluble in the lipid bilayer of the cell membrane.
Explanation:
I found it on google lol
Ions are too large molecules to diffuse through the cell membrane hence require some proteins to facilitate their transport. Ions channels helps in transporting the ions through the cell membrane and the flow of current through the membrane.
What are ion channels?
Ion channels are the type of transport proteins which are present in the cell membrane that facilitates the movement of ions through the membrane. Cell membrane is selectively permeable in nature and thus does not allow many molecules to transport through it.
Ion channels facilitates the passive movement of ions across the cell membrane and are essential for cell survival. Ion-channels helps in elucidating the structure-function mechanisms of the proteins present in the membrane. Ion channels help in creating ion gradient and moving charge through the membrane.

The complete question is as follows:
The diagram shows water molecules as solid ice at 0°C and as a liquid at 25°C. Explain why the arrangement of water molecules is different in ice and water.
Answer:
In low temperatures, hydrogen bonds between water molecules become stable as a result of the movement of these molecules are slow in low temperature which leads to the crystalline form of water due to hydrogen bond. This crystalline form is ice.
on the other hand at a higher temperature water molecules found in liquid form due to the faster and rapid movement of water molecules as hydrogen bonds keep breaking and forming in this setting.
