Answer:
The plasma membrane is selectively permeable
Explanation:
hydrophobic molecules and small polar molecules can diffuse through the lipid layer, but ions and large polar molecules cannot. Integral membrane proteins enable ions and large polar molecules to pass through the membrane by passive or active transport.
Answer:
By providing the numbers in which methane is more powerful than carbon dioxide the author is appealing to the scientific facts to convince people that the greenhouse effect is destroying our planet, and that global warming is a reality that we must counter attack and treat as a priority.
Explanation:
For anyone with this question as a multiple choice question, itś D.
Answer:
42,5 mL
Explanation:
We need to use the serial dilution formula beacuse we start with a stock concentrate solution and we need to prepare a new less concentrated one.
<u>DF in the dilution factor, Vi is the initial volume and Vf is the final volume.</u>
The first step is to have the same measurment unit so we need to convert 345 µg to mg.
we know that 1 µg equals 0,001 g, hence:
now the final volume is 0,345 mg protein/ mL and the inital volume is 15mg protein/mL, both of them are in the same unit so we can use the formula
Now since the question said that we already have 1.0mL of the amylase stock solution we need to subtract that 1.0mL to the 43,5 mg protein/mL
So, we need 42,5 mL of diluting buffer if we want a final concentration of 345 µg protein/mL (0.345 mg protein/mL)
Answer:
Neural networks
Explanation:
The neuron is the structural and functional unit of the nervous system. The neuron is also known as a nerve cell. The neuron is the largest cell of the body that helps to communicate or transmit signals. A neuron has an axon body, dendrites, and terminal region. The transmission of the signal from one neuron to another through the axon terminal. Large numbers of neurons are present in the human body system that coordinates the whole body system. Neural networks contain a massive amount of neurons whose architecture is based on neurons. So, the correct answer to the given question is neural networks that use massively parallel systems based on neurons.
The three main parts of RNA nucleotide are:
- A nitrogenous base
- A pentose sugar and
- One or more phosphate groups.
