Answer:
Embryo
Explanation:
When its organ systems start to develop, it's called the embryonic period. Hence, the correct term will be embryo.

What causes evolution to occur in organisms? Explain the process of evolution and how it is driven by various factors.
Answer:
Evolution occurs when these heritable differences become more common or rare in a population, either non-randomly through natural selection or randomly through genetic drift. This occurs because organisms with advantageous traits pass on more copies of these heritable traits to the next generation

which statement best describes a cause and its effect during the process or muscle contraction?
Answer. The most appropriate statement that is explaining the effect and cause during muscle contraction is. “The release of calcium ions causes myosin and actin to attach to each other.” The activation of muscles helps in the generation of muscles that send out the signals to the neurons.

Why do large organisms require a transport system?
Answer:
The surface area to volume ratio of an organism decreases as its size increases. Ultimately helps organisms, but at the other hand, can't move across the membrane on its own to bring materials like nutrients and water in their cells, or to remove waste material. Specialized transport systems are required for large multicellular organisms.
Explanation:
Organisms that live in the tundra have developed unique adaptations that aid in their survival. Ursus maritimus has a variety of adaptations which enable it to survive in the tundra. It is the largest terrestrial carnivore, but it is also an excellent swimmer that spends much of its time in and near the water hunting its favorite food. It has large paws with small bumps to provide traction as it walks across the ice. Its fur is helpful as camouflage during the winter months, but not as helpful during the summer. Which organism has the adaptations described that enable it to survive in the tundra
Answer: The organism that has the adaptations described that enable it to survive in the tundra is the POLAR BEAR.
Explanation:
ADAPTATION is defined as the process by which an organism becomes fitted to its environment thereby enabling the organism to live successfully and reproduce.
In any population, an organism is able to survive if it has features that help them to fit and compete successfully in that environment.
From the question, a typical example was given concerning the POLAR BEAR (Ursus maritimus) and it's best fitted environment which is the tundra.
The tundra is a type of biome that is treeless marshy vegetation which is composed mainly of dwarf shrubs. It's has a cold climate (Arctic region) with long icy winters and very short summer with an average temperature of 10°C.
Ursus maritimus has a variety of adaptations which enable it to survive in the tundra. These adaptations include:
--> The presence of a thick coat of insulated WHITE FUR: this helps it to survive the cold environment by acting as an effective insulator. The fur is also found at the base of its large paws with small bumps, which protects it against cold surfaces and provides its with a better grip of ice as it walks across it. It also gives it a concealing coloration making it unnoticed while it stalks its prey in the snow. These are the features that enables it survive the terrestrial environment if tundra.
--> it also has some aquatic adaptations which enables it to hunt it's favourite food which is seals. The presence of large front paws which are slightly webbed allows them swim for a long distance in search of food.
