White blood cells structure are quite varied, and different kinds have different functions. These are a few options:
1. The flexibility of the plasma membrane allows bacteriophage and increases mobility in pursuit of invaders.
2. Beta cells put out chemical antigens to eliminate invaders chemically.
3. Various white cells display proteins on their plasma surfaces to communicate the composition of the pathogen.
4. White cells (unlike red blood cells) have a nucleus, which allows the synthesis of new chemicals in response to various invaders.
5. White<span> blood cells tend to have a higher surface to volume ratio than other cells because the are more amorphous. That would lead to a relative increase in the plasma membrane, which contains receptors for identifying.antigens. T</span><span>he white blood cells may be more receptive to detection of antigens due to a higher surface-to-volume ration.</span>
Its a process that happens in an organisms cells that converts biochemical energy from nutrients into adenosine triphosphate and then releases waste products
Answer:
The correct answer is option B) "Normal vaginal pH is acidic (4 to 5), which protects from infection".
Explanation:
Vaginal flora, or vaginal microbiota, is defined as the group of microorganisms that a healthy vagina normally has. At normal conditions, vaginal pH is acidic, which functions as a protective mechanisms because vaginal flora prosper at this condition and avoids unwanted bacteria to growth. A pH above 5, is an non healthy environment and could cause vaginal infections such as bacterial vaginosis.
Answer:
To summarize, meiosis is a cellular process in which a diploid parent cell divides into four haploid daughter cells. One very important event in meiosis is crossing over, which occurs between prophase and metaphase I. Crossing over increases genetic variation. The haploid cells produced through meiosis are otherwise known as gametes.
Explanation:
Coal, petroleum, and natural gas are all fossil fuels. Coal is of plant origin while petroleum and natural gas are made from dead organisms, like zooplankton and algae.
