Answer:
Females have two copies of the X chromosome, while males have one X and one Y chromosome. The 22 autosomes are numbered by size. The other two chromosomes, X and Y, are the sex chromosomes. This picture of the human chromosomes lined up in pairs is called a karyotype.
Explanation:
At some convergent boundaries, an oceanic plate collides with a continental plate. Oceanic crust tends to be denser and thinner than continental crust, so the denser oceanic crust gets bent and pulled under, or subducted, beneath the lighter and thicker continental crust. This forms what is called a subduction zone.
Dendrite; axon; synapse
These are parts of the neuron which is considered as the basic unit of nervous system. The cell responsible for receiving sensory input from the external environment. The stimulus will be transported in an electrical signal via neuronal parts. Axon transmit signal to the other neuron. Dendrites are the receiving part of the neuron. Synapse is the space between each neuron where elctrical impulse is converted into a chemical signal via neurotransmitters.
Size and the ability to carry objects with it
Answer:
Dogs are wonderful human companions. They are the first species that humans domesticated and they have a long history of close relationships with people.
If you spend any time with dogs (I have two wonderful adopted dogs who shower me with affection and fur), then you see first-hand the many ways that dogs can respond to their owners.
