List one factor that you imagine would limit settlement on top of living organisms. The panels hang vertically from the side of
SIZIF [17.4K]

One factor that would limit the settlement on top of living organisms is the panels hang vertically from the side of a dock.

The factors that affect settlements can explain how an organism adapts to its environment. There can be numerous factors based on the situations that can limit the settlement of an organism in its new environment. Competition, predation, disturbances, resources, etc can affect the establishment of a species in an area.

A set of panels hanging vertically can hinder the settlement on top of living organisms. Many organisms are known to survive in the harsh stormy seas and many are known to live in places where freshwater and ocean surface water mix (estuaries). But if the place where the animal such as crabs and snails have to reach is hung vertically it might be difficult for them to establish themselves as it will be harder for them to reach and hang on to the panels.

Pls answer its due soon!!!
pickupchik [31]

Explanation:

Meiosis makes genetic variety possible. It makes sperm & egg cells called gametes. Each gamete has 23 chromosomes. To make a diploid cell two gametes (sperm & cell) come together.

During prophase 1 the chromosomes pair up with their homologous pairs so they can transfer their genetic information and exchange it between each other. It makes recombinant chromosomes that influence the genetic diversity between the same people.

Now they are in metaphase 1, the chromosomes are in pairs in the middle of the cell. In anaphase 1, the chromosomes are pulled away by the spindle fibers. Then in telophase 1, there are two formed nuclei. Cytokinesis 1 then splits the cytoplasm.

Now they are in meiosis 2. During prophase 2, there are chromosomes and the spindles are starting to form again without crossing over like in prophase 1. In metaphase 2, chromosomes are going to line up in the middle in both cells unlike during metaphase 1 where the chromosomes were only in pairs.  In anaphase 2, only the chromatids are being pulled away by the spindle fibers. Next in telophase 2 the nuclei reform and the 2 cells are each going to divide into 4 cells. Finally, cytokinesis completely splits the cytoplasm.

Keeping in mind that each sex only produces one type of gamete cell (sperm or eggs), and of the independent assortment and crossing over of chromosomes, the end result will be diversity.

When water is distilled, any solutes dissolved in the water are left behind. Is distilled water hypertonic or hypotonic compared
Illusion [34]

Answer:

Hypotonic

Explanation:

Tap water contains a lot of solutes and ions that are absent in distilled water. The solution that has more solutes (more dissolved solids) will be the <em>hypertonic</em> solution.

Here, distilled water has no solutes, making it <em>hypotonic</em>.
