Answer:

True

Explanation:

When the resting potential of the membrane is changed, the membrane becomes either more negative inside or less negative. This small deviation from the resting potential is called graded potential. A graded potential occurs when a stimulus triggers opening or closing of the mechanically gated  or ligand-gated channels present in the plasma membrane.

For example, the presynaptic neuron releases neurotransmitters in response to a nerve impulse. The neurotransmitter binds to receptors present in the plasma membrane of the postsynaptic neuron and triggers the opening of the ion channels to allow the inflow of particular ions to flow. The flow of ions changes the voltage across the membrane. This change in membrane voltage is a postsynaptic potential and is a type of graded potential.

In which climate would City Q be located if its average yearly temperature was below 0°C and its annual precipitation was less t
goldenfox [79]

Answer:

C. Polar

Explanation:

The city Q is most likely to be present in the polar region. The polar climate regions do not have any warm summers. The average temperature in a polar region is predicted to be less than 10 °C. About 20% of the earth is known to have the polar climate. Annually, less than 25 cm rain or precipitation is noted in the polar region. Hence, the city Q is most likely to be located in the Polar region.

"Since records began in 1958, the carbon dioxide concentration in the atmosphere has decreased."A. TrueB. False
4vir4ik [10]

Answer:

False

Explanation:

Carbon dioxide is an important greenhouse gas found in the atmosphere. Since the start of the Industrial Revolution, record of the concentration of carbon dioxide in the atmosphere have been said to increase by more than about 45%. Recent records indicate concentration to be highest, of which has been linked to the cause of global warming and climate change.

Human activities such as burning of fossil fuels, bush burning, deforestation have lead to a remarkable increase in the concentration of carbon dioxide in the atmosphere.

How does artificial selection and genetic engineering differ
notka56 [123]
Genetic engineering is actually changing the genes in a plant or animal but artificial selection with animals is putting a male and a female with desirable traits together so that the offspring will have the traits with plants it is mixing the pollen from both plants together and putting the mixed pollen on one of the plants so that the seeds will produce the desirable gene in the plant
