Answer:
33
Explanation:
Gametes (sperm or egg) have half the chromosome of a diploid cell. That's why they are haploid cells.
If chromosomes come from a cell with 66 chromosomes, sperm will have 66/2 = 33.
That's why us humans have 46 chromosomes, but our egg or sperm has only 46/2 = 23 chromosomes.
Answer:
33 chromosomes
Explanation:
The cell undergoes reduction-division to produce 2 daughter cells with equal number of chromosomes. Hence, the sperm cells will have 33 chromosomes.

The freezing point is the point at which liquid water turns into ice.
What is freezing point?The freezing point is the point at which liquid water turns into ice. The freezing point of water is about zero degrees centigrade.
Since water boils at about 100 degrees centigrade, it then follows that the liquid range of water is 0 - 100 degrees centigrade. above or below this temperature, water does not exists in the liquid state.

The motion of molecules and the transfer of energy decreases with increase in volume of the solution.
What is effect of volume in motion of particles?The volume of a solution is inversely proportional to the motion of the molecules of a substance.
An increase in volume results in a decrease in the motion of particles due to a decrease in the frequency of particles and thus, less energy is transferred.
Therefore, the motion of molecules and the transfer of energy decreases with increase in volume of the solution.

A snow-covered mountain has a higher albedo than a dark-colored corn field. Therefore, it will reflect solar energy _____ than the field. (lower, more, less).
A snow-covered mountain has a higher albedo than a dark-colored corn field. Therefore, it will reflect solar energy more than the field.
Does snow have a high or low albedo?Dark surfaces absorb the rays from the sun (low albedo). Ice- and snow-covered areas have high albedo, and the ice-covered Arctic reflects solar radiation which otherwise would be absorbed by the oceans and cause the Earth's surface to heat up.
Why does snow have a high albedo?Freshly fallen snow reflects incoming solar radiation very well and therefore has a high albedo. New snow typically has an albedo of 0.96 to 0.98 in the visible and near-UV range (Grenfell et al., 1994), and 0.8 averaged over the entire wavelength spectrum.

Which represents the cross between parent plants if one is heterozygous and has yellow-colored pods and the other is homozygous and has green-colored pods? yy ´ yy yy ´ yy yy ´ yy yy ´ yy
The cross between parent plants if one is heterozygous and has yellow-colored pods and the other is purebred and has green-colored pods is Yy×yy.
What is Heterozygous?Heterozygous may be defined as the existence of two distinguishable alleles at a distinct gene locus.
In this condition, Yellow is dominant over green i.e. Y>y. Heterozygous means the existence of two distinguishable alleles at a distinct gene locus. So, the genotype of one parent is Yy, while the other parent is purebred and has green-colored pods. Hence, the genotype is yy.

Sayid listed some characteristics of waves in a chart. Part of his chart is shown.
A 1-column table with titled Characteristics of Waves. The column labeled Electromagnetic Waves has entries travel in straight lines, move only through matter, involve interactions with magnetic fields.
Which of these would correct Sayid's error?
Change the heading of the chart to “Mechanical.”
Replace “travel in straight lines” with “move in curved paths.”
Add “move due to particles bumping into each other” to the chart.
Change “move only through matter” to “move through space and matter.”
Answer:
Change “move only through matter” to “move through space and matter.”
Explanation:
Electromagnetic wave like light can travel thru both space and matter. Ever tried to shine a flash light thru a water bottle? The light passes thru the water and the bottle (both are types of matter: liquid and solid) and reaches the other side.
Ever see Suns ray enter your eyes? The light travels thru the vast empty space (our solar system) to reach earth.
Thus, electromagnetic waves can move thru both space and matter.
Electromagnetic waves have the ability to move through matter as well as through space. So the correct option is Option D.
What are the characteristics of Electromagnetic waves?An electromagnetic wave is a type of radiation that travels through space. Electromagnetic waves form when an electric field meets a magnetic field.
Electromagnetic waves do not require molecules to travel. Unlike sound waves, which travel through matter by smashing molecules together, electromagnetic waves cannot travel through a vacuum such as space. Instead, they can travel through the air, solid matter, and even space. This makes electromagnetic waves very useful for many technologies.
There are many different types of waves in the electromagnetic spectrum, ranging from radio waves that are as long as a building to gamma rays that are smaller than a nucleus of an atom.
