I believe the answer is a. thick layer of blubber
Mammal is an warm-blooded animal that need to keep their body warm. Organ that could insulate the heat would be beneficial to keep the temperature, like layer of fat or thick fur. The example of marine mammals would be dolphin, whale, sea lion and polar bear. Thick fur will not give much benefit for mammals in water, so only polar bear have thick fur. But all of them has thick layer of blubber, so option A will be the most appropriate.
Paleoanthropology uses the fossil record to examine the anatomy and behavior of our relatives in the past.
What is Paleoanthropology?
- By reconstructing evolutionary kinship lines within the family Hominidae using biological evidence (such as petrified skeletal remains, bone fragments, and footprints), paleoanthropology, also known as paleo-anthropology, seeks to understand the early development of anatomically modern humans, also known as hominization (such as stone tools, artifacts, and settlement localities).
- Primatology, palaeontology, biological anthropology, and cultural anthropology are all combined in one area.
- Genetics is becoming more and more important as technology and methodologies progress, especially when it comes to analysing and comparing DNA structure as a crucial tool for studying the evolutionary kinship lines of related species and genera.

Answer:
The correct answer will be - in the bacterial cells
Explanation:
The complexity of life began on Earth when the simple amoeba-like organism started ingesting the bacterial cells. The ingestion of the aerobic respiration performing bacteria formed the mitochondria and ingestion of the photosynthetic bacteria formed the chloroplast of the cell. The bacteria while evolution lost their identity and now cannot live without the host cell.
This hypothesis was supported by the evidence like a comparison of the Ribosomes of this organelle is similar to the prokaryotic bacteria as the bacterial cell.
Thus, in the bacterial cells is the correct answer.
