In an experiment the HYPOTHESIS is tested. The hypothesis is the assumption, that you make about something. Example would be, you believe (hypothesize) that the baking soda will react faster in vinegar than in water. You then test it out (or preform and experiment) to see if your hypothesis is correct or wrong.

Match the terms to their definition. 1. chromosome a cell whose nucleus is not bound by a membrane 2. eukaryote a genetic charac
yanalaym [24]

Answer:

1. chromosome: tight coils of DNA

2. Eukaryote: a cell that has a membrane-bound nucleus

3. Gene: a specific sequence of DNA nucleotides that carry hereditary traits

4. Prokaryote: a cell whose nucleus is not bound by a membrane

5. Trait: genetic characteristic of an individual

Explanation:

Chromosomes are the thread-like structures that appear during cell division. Each chromosome is made up of DNA tightly coiled with its packing proteins.  

A cell is defined as eukaryote or prokaryote on the basis of the presence of a membrane-bound nucleus. The cells that lack the membrane-bound nucleus and other membrane-bound organelles are called prokaryotic cells. Example: bacteria.

The cells that have a membrane bound nucleus in which DNA is present are called eukaryotic cells. Example: Plant cells.

A stretch of DNA that code for a particular protein and thereby regulate specific genetic trait is called a gene. Genes are present on chromosomes and are carried from one generation to next to maintain the genetic traits.

The features of living beings regulated by the gene are called trait. Example: skin color, eye color, etc.

During which phase of mitosis do the nuclear membrane, nucleolus, and nucleus dissolve? metaphase prophase anaphase telophase
Mekhanik [1.2K]
Prophase 
During the prophase stage of mitosis, the nucleus seems to disband itself. The nucleolus suspends itself and finally, the nuclear membrane disassembles itself. This is because of the undergoing process of copying and dividing. 
Mitosis is a functional cell dividing process that helps the cells repair or rejuvenate itself because of apoptosis and other factors.

If the first low tide occurs at 5:10 a.m. on Friday when will the next low tide occur​
jonny [76]

The correct answer is - 5:35 PM on Friday.

The low tides, as well as the high tides, occur two times in a lunar day, on exactly every half a lunar day passed. A lunar day is 24 hours and 50 minutes long, so every next low tide, or high tide, appears after 12 hours and 25 minutes after the previous one. In this situation we have a low tide that has appeared at 5:10 AM on Friday, so in order to calculate when the other low tide will appear we need to add 12 hours and 25 minutes on it, and that will gives the information that the next low tide will appear at 5:35 PM on Friday.
