Answer: directional selection, disruptive selection and stabilizing selection
Explanation:
Natural selection is when organisms adapt to the environment and pass down these adaptations to their offspring when they breed
Answer:
Explanation: The first Australopithecus fossil was found in a lime quarry at Tuang, it was found by Raymond Dart in November 1924.
Answer:
The right answer to this question is option D. Convergent evolution.
Explanation:
Convergent evolution is a process defined by when an organism develops the same, or at least near that, characteristics, for a specific reason, but they don't have the same origin. In this case, the cacti in both deserts have pretty much the same characteristics, and this happens because both these plants need water to survive, and in order to save it, they have barrel-shaped stems, short-lived leaves, and spines. All of these things help them in saving the water and capturing it when it's possible.
The convergent evolution is when both these organisms develop equally, but are not originally from the same place, the environment being the one to shape this.
Diploid refers to a cell that has two copies of each chromosome. One way that a diploid organism could have an offspring that are 3n (triploid) or 4n is when the chromosomes don't separate during meiosis.
Triploid refers to some cell that have 3 copies of each chromosomes for a total of 69 chromosomes.
Answer:
Osteoblast, osteocytes and osteoclasts are responsible for breaking down bone during remodeling.
Explanation:
The process which is responsible during bone formation in equally in initial and later stages of remodelling, they are the bigger cells which are responsible for the synthesis and mineralisation of bone. Osteocytes are the rich in cells in the bone tissue, which is helpful in detection of the mechanical loading, also manages the in bone formation and bone resorption. Osteoclast are cells that disintegrate the bone to start normal bone remodelling and also contemplate bone loss in pathologic condition by growing its resorptive capacity.
