Cations, lose

Explanation:

Positive ions are cations and they result when an atom lose electrons.

An atom is made up of subatomic particles:

  • Protons are positively charged particle in the nucleus of the atom
  • Neutrons carry no charges and they share the nucleus with protons.
  • The electrons are negatively charged.
  • When an atom loses an electron, it becomes a positive ion because the number of protons is now more than the number of electrons.
  • An anion forms in a reverse way.

ICE Princess25 [194]
The paramecium has two nuclei, a big and small one. The big one operates as the director of the cell's activities, rather like a little brain. The smaller one is used for reproduction. The paramecium splits in half (fission) just as the ameba does. First the smaller nucleus splits in half and each half goes to either end of the paramecium. Then the bigger nucleus splits and the whole paramecium splits. Occasionally two paramecium exchange material and form a new paramecium. This is called conjugation. 

<span>Conjugation in Paramecia occurs in the following way: </span>

<span>a). The formation of ciliary contacts. </span>
<span>b). Local loss of cilia and formation of narrow contacts between anterioventral somatic cell membranes </span>
<span>c). Formation of small cytoplasmic bridges (which allow for the exchange of molecular components only). </span>
<span>d). Their enlargement enables the cells to exchange micronuclei. </span>

<span>Bacteria exchange plasmid material and the Paramecia exchange micronuclei.

Good luck to Steve! How is it in Neptune? XD</span>

liberstina [14]

The hypothesis that the scientist could test in his investigation is as follows: IF plants are given more than 2.0mg of magnesium, THEN their growth will be negatively affected.

<h3>What is an hypothesis?</h3>

Hypothesis is a tentative conjecture explaining an observation, phenomenon or scientific problem that can be tested by further observation, investigation and/or experimentation.

An hypothesis is commonly referred to as an educated guess because it tends to provide a temporary explanation for a phenomenon.

According to this question, a scientist investigated whether giving plants different quantities of magnesium affected their growth. He measured growth by counting the number of new leaves produced.

The hypothesis of the scientist regarding the above experiment could be as follows: IF plants are given more than 2.0mg of magnesium, THEN their growth will be negatively affected.
