Answer:
You either are referring to the fish Chordate, or the animal classification. In the case of the classification it is literally any animal that has developed any sort of dorsal fin, for example some snakes can fall under this classification.
Answer:
Seaweed (producer) → Shrimp (primary consumer)→ Crab (secondary consumer) → Octopus (tertiary consumer)
Explanation:
In a food chain, there are organisms of different trophic levels present. Food chain, the chain or linear network or representation of a line of the food web that always starts with a producer as sea-weed in the given food chain and ends with a predator or third or highest consumer which is Octopus here and in between the different level of consumers from the primary consumer that depends on the producers and secondary consumer depends on primary and so on.
Seaweed (producer) → Shrimp (primary consumer)→ Crab (secondary consumer) → Octopus (tertiary consumer)
Answer:
The question lacks options, the options are:
parents?
A.100% red/white-feather chickens.
B.50% white-feather chickens and 50% red/white-feather chickens.
C.33% white-feather chickens, 33% red-feather chickens, and 33% red/white-feather chickens.
D.25% white-feather chickens, 25% red-feather chickens, and 50% red/white-feather chickens
The Correct answer is D
Explanation:
According to the question, the hybrid chicken has a mixture of red and white feather phenotypes expressed at the same time. This tells us that the red and white alleles are CODOMINANT in the chicken i.e. none is dominant or recessive over the other.
Let's assume that (R) allele is the red feather colour while (r) allele is for white feather colour. Therefore, the red/white feathered chicken will have a Rr genotype. In a cross between two red/white feathered chicken (Rr), the following offsprings will be produced RR, Rr, Rr and rr
RR- Homozygous red feather d chicken (1/4 × 100=25%)
Rr- Hybrid Red/White feathered chicken (2/4 × 100=50%)
rr- Homozygous white feathered chicken (1/4 × 100=25%)
