Answer:
answer is d
The reproductive cells of an organism also called the sex cells in either male or female undergo the process of meiosis to reduce the diploid number into a haploid number ie reduction into half the original number.
This is to ensure that during reproduction, with the coming together of haploid sex cells (both haploid sperm and the haploid egg cell). A diploid organism can be produced.
Answer:
340.9°k ~ 67.8°C
Explanation:
This is an example of Gay-Lussac's law, which states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature. This means that if the volume increases, so does the temperature, and vice versa.
The equation for this gas law is:
P1/T1 = P2/T2
Known
P1 = 198 kPa
T1 = 27°C + 273.15 = 300°K ← Temp. must be in Kelvins
P2 = 225 kPa
T2 = ?
Solution
Rearrange the equation to isolate T2
Input the known values and solve.
T2 = T1P2/P1
Where:
T2 = 300°K × 225kPa/198kPa = 340.91°K
T2 in °C = 340.91°K − 273.15 = 67.8°C

Answer:
1.878g
Explanation:
Volume = 30.0ml
Density = 0.626gcm−3
Mass = ?
Be careful in this kind of questions to check for the units. In this case one has to remember 1 mL equal 1 cm³ so density = 0.626g/ml
The relationship between all three parameters is given by the equationn below;
Mass = Density * Volume
Mass = 0.626g/ml * 30 = 1.878g
Answer:
The another word for microorganism is microbe
