Student 2 discussion is true as distance between Earth and the Sun remain same, if the seasons changes were due to the Sun-Earth distance, then both hemispheres of Earth would have the same seasons at the same time.
What is hemisphere ?A hemisphere refers to half of the earth surface, that is divided into northern hemisphere or the southern hemisphere, the cutting of the sphere into two equal halves with one having flat side.
Geometrically the hemisphere is a 3D shape it is half of the sphere is flat and the other side is a circular bowl and it is formed when a sphere is cut at the exact center having two equal hemispheres.
A hemisphere has a surface area which is curved, no edges and no vertices, not a polyhedron, but it has one circular base and one curved surface.
The diameter of a hemisphere is a line type of segment that passes through the center and touches the two opposite pole , the radius of a hemisphere is from the center to a point on the curved surface of the hemisphere.

Select all that apply. have a nucleus contain cytoplasm comprise most multi-celled organisms mostly single-celled organisms have membrane-bound organelles are the smallest unit of living matter are produced by division of another cell contain DNA
Answer:
have a nucleus - Eukaryotic
contain cytoplasm - Both
comprise most multi-celled organisms - Eukaryotic
mostly single-celled organisms - Prokaryotic
have membrane-bound organelles - Eukaryotic
are the smallest unit of living matter - Both
are produced by division of another cell - Both
contain DNA - Both
Explanation:
1. Eukaryotic cells are cells that possess a membrane-bound nucleus that houses their genetic material.
2. Both eukaryotic and prokaryotic cells have a cytoplasm, which is the gelatinous substance where all other organelles and substances are found.
3. Most multicellular organisms comprises of eukaryotic cells.
4. On the other hand, most single celled organism, are Prokaryotic.
5. Eukaryotic cells, in addition to the possession of a membrane-bound nucleus, they also possess membrane-bound organelles e.g mitochondria, endoplasm reticulum.
6. Cells, generally, are the smallest unit of living matter. This comprises of both eukaryotic and prokaryotic cells.
7. Likewise, all cells arose from already preexisting cells according to the cell theory. Therefore, both eukaryotic and prokaryotic cells are made by the division of another cell.
8. Both prokaryotic and eukaryotic cells have a genetic material like DNA where they store genetic information.

oxygen and nutrients?
Answer:
The heart, blood and blood vessels work together to service the cells of the body. Using the network of arteries, veins and capillaries, blood carries carbon dioxide to the lungs (for exhalation) and picks up oxygen. From the small intestine, the blood gathers food nutrients and delivers them to every cell.

The images below show the same cell, before and after reaching equilibrium. Which statement best describes what happened as the volume of the cell increased
The missing part of the question and group of options is attached as an image.
Answer:
The correct answer is - D - The number of solvent particles outside the cell decreased.
Explanation:
As the solution reached equilibrium the concentration of the solute is equal inside the cell and outside the cell, so the number of particles of the solvent must increase inside and decrease outside of the cell.
The cell volume increased due to the flow of the solvent from outside to the inside of the cell this type of diffusion of solvent is known as osmosis which leads to the swollen or bigger cell.
Answer:
The number of solvent particles outside the cell decreased.

Are the seasons (summer or winter) the same in the Northern and Southern Hemispheres
at the same time? When it is summer in the Northern Hemisphere, what season is it in the
Southern Hemisphere?
Answer: No they don't occur at the same time
Summertime in the northern hemisphere happens when it is winter in the southern hemisphere, and vice versa.
The tilt of the earth causes the seasons. The northern hemisphere's summertime means that the northern part of the earth gets more sunlight compared to the southern half, so the southern half experiences winter.
With the tilt held at the same angle, the earth revolves to another point in space, so that the northern hemisphere receives less sunlight and the southern hemisphere gets more. So the seasons swap.
Answer: Winter
Explanation: The tilt of the Earth determines the seasons for the Northern and Southern Hemisphere. When the Northern Hemisphere tilts toward the Sun, it experiences summer. At the same time, the Southern Hemisphere tilts away from the Sun. It experiences winter.
In horses, the Overo gene, Ov, produces a white splotch pattern on the coat. The overo phenotype is seen only when a horse has one Ov copy, Ovov. Horses with two Ov copies, OvOv, die soon after birth and are called white overo because they are completely white. Horses with no Ov copies are solid colored, ovov. The Leopard complex gene, Lp, shows incomplete dominance and controls white spotting. One Lp allele, Lplp, produces the leopard phenotype, in which there are spots everywhere. Two Lp alleles, LpLp, produce the fewspot phenotype, in which the horse is mostly white with colored spots. A horse that is both overo and leopard is called pintaloosa, and these horses are spotted with splotches. A horse that is overo and fewspot is considered fewspot because the white areas from Lp is indistinguishable from the white from Ov.
Number of:
Solid:____
Fewspot:_____
White Overo:______
Answer:
Hello your question is incomplete below is the missing part
Suppose that 16 pairs of pintaloosa horses have one offspring per pair. How many of each phenotype would be expected? Determine the number out of 16 expected for each phenotype. Only count phenotypes for offspring expected to live past one week of age.
Answer :
Number of
solid, fewspots: 1/16
solid, leapord: 2/16
solid, white: 1/16
Fewspots: 2/16
white overo: 2/16
Explanation:
Using the given information it can seen that one copy of OV will result in Overo, whereas two copies OVOV offspring will die soon after birth. If 16 pairs of pintaloosa (OVovLPlp) horses are mated and each have one pair of offspring, then it can represented in the table attached below:
from the table we can deduce that :
Number of
solid, fewspots: 1/16
solid, leapord: 2/16
solid, white: 1/16
Fewspots: 2/16
white overo: 2/1

How are Gymnosperm and Angiosperm plants different?
Answer:
Hey! :D
Explanation:
The gymnosperms, also known as Acrogymnospermae, are a group of seed-producing plants that includes conifers, cycads, Ginkgo, and gnetophytes. The term "gymnosperm" comes from the composite word in Greek: γυμνόσπερμος, literally meaning "naked seeds". The name is based on the unenclosed condition of their seeds. The non-encased condition of their seeds contrasts with the seeds and ovules of flowering plants, which are enclosed within an ovary. Gymnosperm seeds develop either on the surface of scales or leaves, which are often modified to form cones, or solitary as in yew, Torreya, Ginkgo.

Explanation:
Monomers are simple molecules that when joined together and form chains become polymers, a process called polymerization, which is mediated by polymerase enzymes.
Monomers are simple molecules that when joined together and form chains become polymers, a process called polymerization, which is mediated by polymerase enzymes.
Peptides and proteins are formed by the addition of specific amino acid sequences. Polysaccharides, or complex sugars, are formed by the addition of monosaccharides, such as glucose. A nucleic acid, such as DNA or RNA, consists of chains or strands that are formed by nucleotide sequences. Lipids are the polymerized form of fatty acids.what are the two main categories of an ecosystem 5th grade

5. Besides being part of the composition of bone, why else do mammals need calcium?
Answer:
It's important for the contracting muscle
Explanation:
Besides being part of the composition of bones, calcium is needed by mammals for the following processes:
Formation of skeletons and teeth.Muscle contraction.Regulation of normal heart rate and nerve functions. Blood clotting. What is Calcium in living organisms?Calcium in living organisms may be defined as an important nutrient that all living organisms require, including humans in order to develop various organs like teeth and bones as well as for metabolic processes.
Apart from being part of the composition of bones, calcium is also required for the proper development of teeth and skeletons. The movement of calcium ions plays an essential role in the contraction of muscles.
The influx of calcium ions into the cells of the heart significantly enhances the heart rate of an individual in the range of 1.6 to 14.10 mm.
It also plays a critical role in blood clotting.
Therefore, it is well described above.
