The correct answer is B. The science of inherited traits
Explanation:
Genetics refers to the field in biology that focuses on studying genes which are the basic units of heredity and therefore the ones that determine inherited traits. Indeed genetic study the way traits are passed through reproduction and also the way genes change over time or express which is closely connected to evolution. Additionally, genetics have been widely studied beginning by the works of Mendel during the 19th century and nowadays the knowledge about genes including the behavior, function, and structure of them is broad. According to this, genetics is defined as the science of inherited traits.
Over time, diabetes damages the small blood vessels in your body, causing the walls of the blood vessels to stiffen. This increases pressure, which leads to high blood pressure.
Answer:
The correct option is C - Professor Scrawll applied 100 nM BurD to the cells for 24 hours, while Dr. Bogey applied 1 nM BurD to the cells for 12 hours.
Explanation:
The correct option is C - Professor Scrawll applied 100 nM BurD to the cells for 24 hours, while Dr. Bogey applied 1 nM BurD to the cells for 12 hours.
As the exotoxin, BurD is very stable and lyse the ankle cells very quickly, more concentration and more time of action should only lyse the cells. Perhaps Dr.Bogey's ankle cells were not lysed because the concentration she used was only 1nM compared to the 100nM concentration used by Dr. Scrawll, and the time period of incubation was only 12 hours compared to the 24 hours used by Dr. Scrawll.
Considering the other explanations given in the remaining options, the concentration and time of incubation used by Dr. Bogey are more than that used by Dr. Scrawll which should only have possibly lysed the cells. Moreover, contamination with bleach also should have only lysed the cells.
Answer:
Neurotransmitters are released from axon terminals via exocytosis
Explanation:
Dendrite is the receiving part of the presynaptic neuron, while axon is the transmitting part of the neuron. So, after initiation, action potentials travel down axons to the terminals. Action potential travels through the membrane of the presynaptic cell causing the voltage-gated channels permeable to calcium ions to open. Ca2+ flow through the presynaptic membrane and increase the Ca concentration in the cell which will activate proteins attached to vesicles that contain a neurotransmitter (e.g. acetylcholine). Vesicles fuse with the membrane of the presynaptic cell, thereby release their contents into the synaptic cleft-space between the membranes of the pre- and postsynaptic cells (exocytosis of the vesicle's content). Neurotransmitter ACh (from the vesicles) binds to its receptors on the postsynaptic membrane and its binding causes depolarization of the target cell (muscle cell). Depolarization occurs because sodium enters the cell as a result of neurotransmitter receptor binding.
A. Bacteria are single-celled.
I think it would be this because humans have way more than one cell, and the other ones are the same as us.
Just guessing
