Answer:
These homologous structure indicates a common ancestry
Explanation:
When 4 organisms show homologous structures, they indicates they belongs to a common ancestor from where the changes takes place in them.
The organs which are structurally dissimilar but functionally same are called as homologous organism.
I’m sorry I’m not smart I don’t know I just need answers for my questions
Answer:
Rockfish larvae are pelagic, there is genetic evidence for limited dispersal within Puget Sound for the quillback and copper (S. caurinus) rockfish (Seeb 1998) as well as for differentiation from coastal populations of brown rockfish (S. auriculatus) (Buonaccorsi et al. 2002). This degree of population structure is consistent with other genetic and otolith studies from coastal Pacific rockfish populations
Answer:
1. emigration the movement of people from one place to another
2. immigration a situation in which resources are being used up at a faster rate than they can be replenished
3. migration the leaving of one's homeland to settle in a new place
4. overpopulation the movement of people to a new country
5. sustainable development a situation in which the birth rate is not sufficient to replace the existing population
Explanation:
Those are the five invertebrate groups in the animal family tree
Answer:
Option C, resulting in variation genes being expressed in different ways due to environmental conditions
Explanation:
Several genetic traits are affected by both internal and external environmental conditions. Some common examples are – height , color of eye, hair color, skin color, and even some genetic diseases.
The internal environmental factors include – gender, temperature etc.
While the external environmental factors include drugs, chemicals, temperature, and light.
Hence, the external environmental condition i.e pH of soil is producing different color of flowers in a given plant
Hence, option C is correct
