First, we consider the parents:
Phenotypes: Polka dots
Genotypes: Pp
Using a punnet square,
P p
P PP Pp
p Pp pp
Therefore, out of four, the phenotypes and genotypes of the offspring will be as follows:
Phenotypes: 3 with polka dots (75%) and 1 with solid (25%)
Genotypes: 1 dominant homozygous (25%), 1 recessive homozygous (25%) and two dominant heterozygous (50%)
The answer is option D.
Around 1 billion nerves reside in your body! The nerve cells unlike many other types of cells does not perform mitosis resulting in paralyzation. :)
Answer:
Glaciers picking up boulders is not a type of erosion
Explanation:
The four main types of river erosion are abrasion, attrition, hydraulic action and solution. Abrasion is the process of sediments wearing down the bedrock and the banks. Attrition is the collision between sediment particles that break into smaller and more rounded pebbles. Hydraulic action is the force of water against the banks compressing air pockets into cracks, which expand and fracture the rock over time. Solution is the process of acidic water dissolving soluble sediment.
<span>the answer is :
permanent magnets
</span>A permanent magnet<span> is an object made from a material that is </span>magnetized<span> and creates its own persistent magnetic field. An everyday example is a </span>refrigerator magnet<span> used to hold notes on a refrigerator door. Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called </span>ferromagnetic<span> (or </span>ferrimagnetic<span>). These include </span>iron<span>, </span>nickel<span>, </span>cobalt<span>, some alloys of </span>rare-earth metals<span>, and some naturally occurring minerals such as </span>lodestone<span>. Although ferromagnetic (and ferrimagnetic) materials are the only ones attracted to a magnet strongly enough to be commonly considered magnetic, all other substances respond weakly to a magnetic field, by one of several other types of </span>magnetism<span>.</span>
Answer: Cellular Respiration and Photosynthesis are almost opposite processes because photosynthesis removes carbon dioxide from the atmosphere while cellular respiration puts back carbon dioxide. Cellular respiration uses oxygen and has it's waste product of carbon dioxide (CO2).
