Which is an SI derived unit measurement?<br><br>0.56 kg<br>01.10 m<br>2730K<br>02.5 N​
balandron [24]

Answer:

02.5 N​

Explanation:

02.5 N​ is a derived unit of measurement.

A derived unit is one that is obtained by combining two or more fundamental units.

                    Force = mass x acceleration

                The unit of mass = kg

                                   acceleration = m/s²

Combining the two;          kg x m/s²  = kgms²

          1N = 1  kgms²

kg, m, k and N are fundamental particles

How are the fluke larvae transferred from the snail (invertebrate host) to the vertebrate host?
Vesna [10]
The eggs of the fluke are passed into water supplies from feces and urine of infected people. After hatching the parasite actively swims and invades the body of a snail, usually by penetrating through the snail's foot. The parasite requires the presence of certain species of snails (e.g., Oncomelania, Biomphalaria, Bulinus) to transform (and multiply) itself into an infective stage, called cercaria.

Explain in 3-4 sentences how mitosis supports the body in<br> everyday function.
Elden [556K]

Answer:

Mitosis is the phase of the cell cycle where the nucleus of a cell is divided into two nuclei with an equal amount of genetic material in both the daughter nuclei. It succeeds the G2 phase and is succeeded by cytoplasmic division after the separation of the nucleus.Mitosis is essential for the growth of the cells and the replacement of worn-out cells. Abnormalities during mitosis may alter the DNA, resulting in genetic disorders.
