Answer:

Weight of the soil (500g)

Explanation:

According to this question, some students are conducting an experiment in order to find out which of the different soils used absorb heat the fastest. For the first test, they put 500 grams of SAND in a beaker and put a thermometer in the sand.

In an experiment, the variables that must be kept constant for all the groups is called the CONSTANT OR CONTROLLED VARIABLE. This is done in order not to influence the outcome of the experiment. In this case, the weight (500g) of the soil should be kept the same for all other tests.

This means that for the remaining soil being tested, 500g of each type of soil should be used.

Answer:

Kingdom Protista.

Explanation:

This is a perfect behaviour of a slime mold which is known to be of the kingdom protista. Slime molds are usually found in lawns, and on the forest floor, deciduous logs and soil too.

  Protists are made up of eucaryotic cells in which the cell structure is complex with a well defined nucleus. Some of them move around with their flagella or by forming pseudopodia also known as their false sheet.

Romashka [77]

Most of the digestion and absorption in the small intestine is accomplished by the duodenum; the longest portion of the small intestine is the ileum.

<h3>What is Digestion and Absorption?</h3>

Digestion stands for the complex function of turning the food you eat into nutrients, which the body utilizes for energy, growth, and cell repair required to survive. The digestion process also concerns creating waste to be eliminated.

Digestion stands for the breakdown of extensive insoluble food molecules into small water-soluble food molecules so that they can be immersed in the watery blood plasma. In particular organisms, these smaller substances exist absorbed via the small intestine into the bloodstream.

Absorption exists as a physical or chemical phenomenon or a procedure in which atoms, molecules, or ions penetrate some bulk phase – liquid or solid material. This is a separate process from adsorption since molecules undergoing absorption stand taken up by the volume, not by the surface.

How can protists exhibit both animal-like and plant-like characteristics?
Kay [80]

A heterotrophic and chlorophyll protist

Food is ingested by protists in three forms. We produce, eat and digest their own organic molecules. Meat ingestion or english bacteria ingests protists. The cell wall and cell membrane are stretched to create an alimentary vacuolum around the foodstuff. Enzymes extract the food inside the food vacuole. At the other side, absorbent protists consume food molecules through their cell membrane by diffusion. In decomposition, absorbent protists play a crucial role. They are assumed to be essential decomponents. Light energy is used to make your own food by big farmers including photosynthetic protists.

Explanation:

Mitosis is a type of cell division in which a cell divides into two daughter cells each having the same number of chromosomes as the parent cell. It ensures that every body cell contains the same number of genes as the parent cell. The cell that have 78 chromosomes have undergone mitosis while the other cells that contain 39 chromosomes undergo meiosis.
