Chromosomes are made from DNA. Genes are short sections of DNA. Genetically identical cells are produced by a type of cell division called mitosis. In sexual reproduction, a male gamete fuses with a female gamete to produce a new cell. This is called fertilisation. Gametes are produced by a type of cell division called meiosis. They contain a single set of chromosomes, whereas body cells contain two sets of chromosomes.
I cannot see the imagine very well would you mind taking another?
Answer:
True, by active transport
Explanation:
The influx and efflux of molecules through the cell membrane depend on the concentration gradient.
When the molecules down their concentration gradient that is from higher concentration to lower concentration are known as passive transport but sometimes the cell has to transport the ions against the concentration gradient.
When the ions move against the concentration gradient, they use energy in the form of ATP molecules and then transport the ions. This is known as active transport.
In the given question, since the sodium ions move inside the cell against the concentration gradient by the active transport.
The Adipose tissue mainly works as storing energy into fat but it also works as an insulating layer that allows less heat to escape the body, as well as offer protection to major organs.
Intrapleural pressures must remain negative to prevent lung collapse.
<u>Explanation:</u>
The intrapleural pressure is the taking place within the cavity of pleural, whose pressure is marginally lower than the atmospheric pressure in what is understood as a negative pressure. The intrapleural pressure is equivalent to or exceeding the atmospheric pressure if the plural cavity is impacted, thus pneumothorax increasing occur.
This negative pressure is at resting mode and brings us a lung-expanding transpulmonary sensation. Put an easier way, if even when exhaling we didn't sustain a mildly negative pressure, our lungs would collapse on themselves as all the air would stream into the lower pressure area. The pressure intrapleural is subatmospheric, which is related to the lungs and chest recoil apart from each of the other.
