Marsupials come to live on two separate continents when both continents were attached to each other.
What is the reason for the presence of Marsupials?Marsupials are the group of organisms that come to live on two separate continents a long time ago when both continents i.e. North America and Australia were joined or attached to each other. The supercontinent named Pangea began to break apart about 200 million years ago which results in the formation of continents.
Before this is broken, the Marsupials move to the Australian part from the North American part so we can conclude that Marsupials come to live on two separate continents when both the continents were attached to each other.

What is genetic variation in plants??
Answer:
Individual differences or population differences are referred to as genetic variations.
Explanation:
Individual differences or population differences are referred to as genetic variations. Plant breeders can use genetic variability/diversity to improve cultivars with desired qualities and generate new cultivars with both farmers- and breeder-preferred traits (yield potential, early maturity, good shapes, taste, color, extended shelf life, easy to prepare) (disease and pest resistance). Plant breeders and local farmers have harnessed natural genetic variability to boost their yield. GA plays a crucial part in the alleviation of poverty as the population grows. Plant breeders benefit from population variation because it allows them to explore the source and develop new cultivars. Mutation, hybridization between incompatible kinds or introgression, wide-hybridization, and recombination could all be used to accomplish this. Mutation, natural selection, environmental diversity, genetic drift, migration, and population size all have an impact on genetic variability.
Answer:
Gene variation in plants often occurs as the result of gene flow. Pollen is dispersed from one area to another by the wind or by pollinators over great distances. Examples of genetic variation in animals include albinism, cheetahs with stripes, snakes that fly, animals that play dead, and animals that mimic leaves.

What can be concluded from the fossils of various organisms is that the organisms evolved to adapt to the environmental conditions of their contexts. Additionally, its morphology changed radically.
What is a fossil?Fossils is a term to refer to the remains of past organisms preserved in sedimentary rocks. The science that deals with the study of fossils is paleontology.
Within paleontology are paleobiology, which studies the organisms of the past (paleobiological entities, which we know only from their fossil remains).
This science is the one that can study fossils in detail and draw conclusions such as the shape of organisms changing as a way of adapting to the environment in which they lived.

What's function of ADH
ADH is the Antidiuretic hormone. This is a brain hormone that induces the kidneys to discharge less water, resulting in less generation of urine.
Arginine vasopressin is another name for ADH. The hypothalamus in the brain produces this hormone, which is then stored in the posterior pituitary gland.Vasopressin is a hormone that promotes vasoconstriction and water reabsorption in the renal tubules of the kidney.The amount of water in the blood is constantly regulated and balanced by ADH.Higher water concentration raises the volume and pressure of the blood. Water metabolism is maintained by osmotic sensors( to sense the osmotic pressure) and baroreceptors(to sense the blood pressure) in conjunction with ADH.ADH deficiency often results in an unusual water metabolism condition called diabetes insipidus. A reduction in either the generation of ADH by the hypothalamus or the release of ADH from the pituitary gland is the major causal factor of diabetes insipidus.Excessive urination( polyuria) is a common symptom of this disease, followed by intense thirst, known as polydipsia.To learn more about the ADH, refer to:-

Six molecules of carbon dioxide plus six molecules of water plus light energy converts to six molecules of oxygen plus sugar, Thus, the correct option is A.
What is photosynthesis?Photosynthesis is the process through which plants use sunlight to create their own nourishment. Through a sequence of reactions, light energy from the sun is turned into chemical energy, which is then stored in the form of food.
In the presence of sunlight, 6 molecules of carbon dioxide (CO2) and 6 molecules of water (H2O) react to form 1 molecule of glucose sugar. During photosynthesis, 6 molecules of oxygen are formed in addition to glucose.
