Hope this helps
The differences arose through genetic mutation. Individual 1’s is neutral, 2’s is helpful, and 3’s is harmful characterize the phenotypes as helpful, harmful, or neutral.
What do you mean by phenotypes?In genetics, the phenotype is the set of observable characteristics or traits of an organism. The term covers the organism's morphology, its developmental processes, its biochemical and physiological properties, its behavior, and the products of behavior.
A phenotypic ratio is a quantitative relation between phenotypes showing the number of times the frequency of one phenotype correlates with another.
Phenotype refers to an individual's observable traits, such as height, eye color and blood type.

Explanation:
sodium (NA) and water (H2O undergo a chemical reaction that produces sodium hydroxide (NaOH) and hydrogen gas (H2). Which equation represents this chemical reaction
Answer:
There are no options in this question, however, the equation can be provided. The answer is:
2Na + 2H2O --> 2NaOH + H2
Explanation:
This question is deacribing the equation between sodium (Na) and water (H2O) to produce sodium hydroxide (NaOH) and hydrogen gas (H2). The equation originally is as follows:
Na + H2O --> NaOH + H2
From the above equation, one would notice that it is not balanced because the number of atoms of each element is not the same on both sides of the equation. Hence, to balance the equation, a coefficient is used to make sure the same number of atoms of each element are on both sides.
We have;
2Na + 2H2O --> 2NaOH + H2

why does cell specialization occur in large multicellular organisms but not in small unicellular organisms? Thanks
Explanation:
Cell specialization is the differentiation of cells to perform very specific function. At the stage of cellular differentiation, the generic cells are transformed into very specialized cells.
Multicellular organisms have very complex body systems. They carry many different tasks. They have to move, find food, excrete, maintain balance within their body system and the environment etc.
To perform these tasks, cells must have specific functions because they would be in need of different materials to carryout the functions.A unicellular organism performs very simple functions of life. They do not require complex biological processes to manufacture their food and carry out life activities.
Cell specialization occurs in large multicellular organisms but not in small unicellular organisms because multicellular organisms have numerous cells but unicellular cells have only one cell.
CELL SPECIALIZATION:
Cell specialization is a phenomenon in living organisms in which different cells perform different and specific functions for the organism that contains them. Cell specialization strictly occurs in multicellular organisms i.e. organisms that possess more than one cell. This is because there are numerous cells to carry out specific tasks.On the other hand, in a unicellular organism i.e. organism that contain only one cell, cell specialization cannot occur. Therefore, cell specialization occurs in large multicellular organisms but not in small unicellular organisms because multicellular organisms have numerous cells but unicellular cells have only one cell.Learn more about cell specialization at: https://brainly.com/question/12683466?referrer=searchResults

What is the charge of the outside of the DNA molecule?
Answer:
It has an alternating chemical phosphate and sugar backbone, making the 'sides' of the ladder. (Deoxyribose is the name of the sugar found in the backbone of DNA.) In between the two sides of this sugar-phosphate backbone are four nitrogenous bases: adenine (A), thymine (T), cytosine (C), and guanine (G).

Which weather patterns are caused by atmospheric pressure differences?
Answer:
Low-pressure systems are associated with clouds and precipitation that minimize temperature changes throughout the day, whereas high-pressure systems normally associate with dry weather and mostly clear skies.
Explanation:
Storms, which are severe weather conditions, develop when air pressure differences speed up air flow.
What do you mean by atmospheric pressure differences ?It is the force that the air above a surface applies to it while gravity pulls the surface toward Earth. Weather is predicted by atmospheric pressure. There will often be clouds, wind, and precipitation when a low-pressure system enters a region. Fair, quiet weather is frequently a result of high pressure systems.
Air density variations, which are connected to temperature, are what are causing this shift in pressure. Because heated air's gas molecules move faster and further apart than cooler air's, warmer air is less dense than colder air.
Thus, various weather patterns are seen with change of atmospheric pressure.

What types of organisms have mitochondria
Answer:
sup ._.
Explanation:
The mitochondrion (/ˌmaɪtəˈkɒndrɪən/, plural mitochondria) is a semi autonomous double-membrane-bound organelle found in most eukaryotic organisms. Some cells in some multicellular organisms may, however, lack mitochondria (for example, mature mammalian red blood cells). A number of unicellular organisms, such as microsporidia, parabasalids, and diplomonads, have also reduced or transformed their mitochondria into other structures.
