The right answer is Filtration.

A water filter is composed of a filtration system that aims to separate the water from the solid particles (residues) by passing it through a porous medium, which allows only the liquids and the finer solid particles to pass through. as the filter holes (porosity). The water that comes out of this filtration system is rid of solid particles larger than the pores of the filter.

Some water filters are designed to make drinking water (very fine filtration, less than the size of a microbe).

A huge amount of water − 7 to 9 l − moves from the blood into the bowel every day, through osmosis and digestive secretions. sin
Alexus [3.1K]
The event order should be:

1. Ingesting food, the small bowel filled with food solutes and become hypertonic. It will attract water from the blood which is hypotonic
2. Food digested, some of it absorbed. The osmotic pressure inside bowel will be reduced.
3. All food is absorbed, the osmotic pressure reduced significantly makes it hypotonic. The blood attracts water as it is hypertonic. This will increase the blood volume

The arrangement of homeotic genes along chromosomes of vertebrate and invertebrate animals corresponds to the expression pattern
Keith_Richards [23]

The arrangement of homeotic genes along chromosomes of vertebrate and invertebrate animals corresponds to the expression pattern of the genes along the anterior-posterior axis of the developing embryo.

<h3>What are homeotic genes?</h3>
  • Homeotic genes are a group of body pattern forming genes which control the development along the anterior- posterior axis of the developing embryo.
  • These encode transcription factors which control and specify the genes involved in body patterning. These provide identity to the segments during embryo formation.
  • Genes located in the 5’ end act on posterior side whereas the genes on 3’ end act on anterior region.
  • Homeotic genes are evolutionary conserved and control body specification, patterning and differentiation.
  • The loss of function of any of the gene changes the body pattern and affects the development.

Explain what happens to an animal cell when it removed from an organism and placed into distilled water
Ivanshal [37]

Answer:

I think it has to do with osmosis

Explanation:

Osmosis is the process of having water pass from a low concentration medium to a high concentration one, given that the barrier (membrane) is semi-permeable.

When a cell is placed into distilled water, hypertonic solution takes place.

A cell may contain many solutes so it is considered hypertonic when compared to distilled water which is hypotonic So in this case, when a cell is placed in distilled water, water moves from outside of the cell to the inside leading to swelling of the cell.
