Answer:
Landmasses include supercontinents, continents, and islands. There are four major continuous landmasses on Earth: Afro-Eurasia, the Americas, Antarctica and Australia.

Explanation:
At the G2 checkpoint, the accuracy of chromosome replication is assessed along with the cell size and proteins within the cell. The cell division will only proceed if all the listed conditions appear all right.
At the M checkpoint, the correct attachment of spindles to the kinetochores of the sister chromatids of each chromosome is assessed. This is to ensure that chromosomes are correctly separated to the opposite poles of the cell.
Answer:
C: All offspring with at least one R will have red flowers.
Explanation:
Mendel's Law of Dominance states that: “In a cross of parents that are pure for contrasting traits, only one form of the trait will appear in the next generation. Offspring that are hybrid for a trait will have only the dominant trait in the phenotype.”
This simply means that if there exists two contrasting traits (I.e Rr), one of the traits will always suppress the other, thereby expressing itself. R suppresses r, thus making the offspring with big R have red flowers. The trait is called a dominating trait and the suppressed is called recessive trait.
yes its (metallic) b/c Relating Metallic Bonds to Metallic Properties. Because electrons are delocalized around positively-charged nuclei, metallic bonding explains many properties of metals. Electrical Conductivity - Most metals are excellent electrical conductors because the electrons in the electron sea are free to move and carry charge.
If neurotransmitter x remains in the synaptic cleft for a long time, the following outcomes are possible:
Prolonged depolarization: Continuous binding of the neurotransmitter to the receptor site of the ligand-gated sodium channel can cause prolonged depolarization of the postsynaptic membrane, leading to sustained neuronal signaling.
Desensitization: Prolonged exposure of the receptor site to the neurotransmitter can cause desensitization, where the receptor becomes unresponsive to the neurotransmitter, reducing the strength of the neuronal signal.
Reuptake: The neurotransmitter may be taken back up into the presynaptic neuron through reuptake transporters, reducing the concentration of the neurotransmitter in the synaptic cleft and reducing the strength of the neuronal signal.
Degradation: The neurotransmitter may be degraded by enzymes in the synaptic cleft, reducing the concentration of the neurotransmitter and the strength of the neuronal signal.

The statement is false. Homo habilis were primarily found in Africa and there is no solid evidence indicating their ability to adapt to diverse climates or populate different parts of the globe.
The statement you've provided regarding Homo habilis is false. Homo habilis, a species of the tribe Hominini during the Gelasian and early Calabrian stages of the Pleistocene, were mainly found in Africa and there's no concrete evidence that they were able to adapt to extreme climates or begin populating different parts of the world. The process of distributing human species across the world is generally attributed to Homo erectus, a later human ancestor that had significant physical and technological adaptations.
