Birds and butterflies don't have a common ancestor because one is a member of a insect and the other is well a bird. They both have different body structure. One has bones and the other has an exoskeleton. hope this helps
None of the above
Consumers by definition produce their own food (from sunlight)
Carnivores feed on other animals, herbivores feed on plants, plants create their own food. whereas scavengers feed on dead animals etc
Answer:
Symbiotic relationship
Explanation:
The relationship between the manta ray and the sturgeon fish is a symbiotic relationship. It is also known as mutualism. It involves two organisms benefiting from each other. The two creatures gain something from each other.
The manta ray is cleansed of the dead skin cells and parasites by the sturgeon fish while Sturgeon fish gains a food source from the the manta ray.
Answer:
A. dihybrid crosses
Explanation:
A dihybrid cross can be defined as a mating experiment between two lines/varieties/organisms that differ in two phenotypic traits. By using pea plants, Mendel performed dihybrid crosses in order to analyze the mode of inheritance of both phenotypic traits at the same time. From these mating experiments, Mendel observed that the inheritance factors (nowadays called genes) sorted independently from one another in the next generation, which is called the principle/law of Independent Assortment.
Answer:
mitosis, cell growth, and differentiation
Explanation:
There are several ways through which plants grow which may include the process of mitosis mainly that involves cell division. The increase in height in plants is attributed to not only cell division but also growth of the newly formed cell.
Mitosis involved division of cell and in cell growth, cells increase their size that ultimately cause growth of plant height. The highly active growth cells are meristem cells that are found at tips of the plants. They are actively dividing zones of plants and with their division and growth plant increases their heights.
Another mechanism, responsible for increase in height is cell differentiation. Differentiation is the process during which cells are specialized to perform specialized function. For example: Xylem are specialized for transport of water. Phloem are specialized for the transport of food. Similarly, some cells are specialized for growth and they are aimed at increasing in size and division that ultimately increase the plant height.
So, mitosis, cell growth, and differentiation are the mechanisms, that increase plant height due to changes in specialized regions of cells in the tips of their branches.
