The answer is B. Vascular plants and invertebrates appeared during this time.
Answer:
Aspartame is found in Nutra sweet which is a modified dipeptide rather than a carbohydrate and they are many times sweeter than monosaccharides galactose because they binds very tightly with the heterodimer GPCR receptors present on the tongue which is made up of proteins called taste receptor type 1 member 2 and taste receptor type 1 member 3.
This tight binding to aspartame generates a neuronal output that is sent to the brain and the brain interprets it as a super sweet compound. It's decrease off rate also contribute to its more sweetening effect.
Therefore the type of binding to taste receptors explains why aspartame is 500 times sweeter in human taste test.
Due to convergent evolution placental mammals (Wolf) are closely related to marsupial wolves (Tasmanian wolf). No, the tree is wrong.
What is convergent evolution?
It is the presence of similar features in animals of different lineages. The structures in these animals have similar functions but are absent in the common ancestors hence they are analogous structures not homologous.
Such convergence of functional, morphological, and structural traits from phylogenetically unrelated species may be a result of random mutation due to selection pressure.
Here, the Tasmanian wolf (marsupial wolf) and wolf (placental mammal) have several morphological similarities but they have unrelated ancestral lineages. Hence they show convergent evolution. These two subclasses of mammals have adapted to a specific food source, locomotor ability, or environment in similar ways.
Hence, the placental wolf and Tasmanian wolf exist sharing the same habitat in different continents former in Asia and the latter in Australia because these two show convergent evolution.

Answer:
It is neural tissue that is dominated by the cell bodies of neurons, neuroglia, and unmyelinated axons, and surrounds the narrow central canal.
Explanation:
Grey matter is a part of the central nervous system that is found on the surface of the brain.
It is a neural tissues that has alot of cell bodies of neurons, neuroglia and contain more unmyelinated axons and surronds the narrow central canal.it is distinguished from white matter because it has alot of cell bodies and unmyelinated axons and also it is not as white as white matter with greyish color.
Grey matter form spinal tracts which are the pathways where signals are sent from the brain to all part of the body.
Answer:
Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor. hope this helps
