Why do people have different traits
Answer:
Despite sharing some characteristics with our peers and our family members, every one of us has a unique combination of traits. Some traits are controlled by genes passed from parent to child, others are acquired through learning but most are influenced by a combination of genes and environmental factors
Explanation:
Some cnidarians are unique in exhibiting polyp and medusa forms. How might their two body forms give them an advantage over species that have only one body form?
Answer:
Explanation:
cnidarians are mostly marine animals. they exibit alternation of generation with two different body forms. their larval stage is polyp and the maturation stage is madusa. these two different forms help them to survive. polyp stage is sessile while medusa stage is free swiming. they can get food migrate and do sexual reproduction. their are also some cniderians that exhibit only one body form. these are less suited to environment as compared to the others that haae two body forms.
What process creates gametes for sexual
reproduction?
• A. Meiosis
• B. Budding
• C. Independent assortment
• D. Mitosis
Answer:
meiosis
Explanation:
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.

1Some moths have a brown body and brown wings, while other moths have a white body and white wings. The brown moths often rest on the bark of pine trees, and the white moths rest on the white bark of aspen trees. If all the aspen trees in an area were cut down, what would be the likely result? (YOO PLEASE ANSWERSSSSS)
Answer:
The poplar tree with the whitest bark is the White or Silver Poplar. It can be distinguished from the white birch fairly easily, even if you can't tell the difference in leaves.

1. cerebellum
2. corpus callosum
3. amygdala
4. spinal cord
Answer:
its answer is 1. cerebellum
Explanation:
The cerebellum is a part of the brain that plays a vital role in virtually all physical movement. This part of the brain helps a person drive, throw a ball, or walk across the room. The cerebellum also assists people with eye movement and vision. Problems with the cerebellum are rare and mostly involve movement .
When 2 alleles are different in the genotype , hybrid
Answer:
A hybrid organism is one that is heterozygous, which means that is carries two different alleles at a particular genetic position, or locus. Therefore, a dihybrid organism is one that is heterozygous at two different genetic loci.

Occasionally cells stop dividing and enter another phase, G. If you damage your liver, new
liver cells can be produced to replace up to 75% of the liver. However, if you sustain brain
damage, your body does not produce new brain cells. Explain this observation using what
you have learned about the cell cycle. Hint: What phase of the cell cycle are the brain cells
in once they mature?
The phase of the cell cycle are the brain cells in once they mature is G0 phase (inactive phase).
What happens in the G0 period?The G₀ phase is the phase of the cell cycle where the cell remains in interphase indefinitely. Generally, highly specialized cells such as nerve cells are found in G0. Depending on the type of cell, stimulation and the return of the cell cycle can occur.
It is important to mention that there are cells that do not divide and that, for this reason, do not pass to the later phase, S. When this happens, the cell remains in a phase called G0.
These cells that do not divide further exist G1 phase to enter an inactive stage called quiescent stage (G0) of the cell cycle.

Explanation:
What part of meiosis is responsible for variation?
Answer:
the double-chromatid homologous pairs of chromosomes cross over with each other and often exchange chromosome segments. This recombination creates genetic diversity by allowing genes from each parent to intermix, resulting in chromosomes with a different genetic complement.
Answer:
The two events that set meiosis apart from mitosis are known as crossing over (or genetic recombination) and independent assortment. These occur in prophase and metaphase of meiosis
During prophase of meiosis I, the double-chromatid homologous pairs of chromosomes cross over with each other and often exchange chromosome segments. This recombination creates genetic diversity by allowing genes from each parent to intermix, resulting in chromosomes with a different genetic complement.
Explanation:
Genetic variation is increased by meiosis
Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote. Recombination or crossing over occurs during prophase I
Often During summer months large bodies of water will experience "fish kill." These do not happen during the winter months. Explain these events using your understand of the properties of water.
Answer: see below.
Explanation:
gases dissolve more in colder water, so in summer the water can become oxygen depleted. Evaporation in summer can reduce water volume; even in summer rainfall climate evaporation rates may exceed precipitation. Evaporation will also cause higher conentrations of solutes of which some may reach toxic levels. Summer sun may also cause algal or cyanobacterial blooms which can further deplete dissolved oxygen and may release toxins into the water.

Explanation:
which statement describes the law of superposition
A. Sedimentary rocks were originally in horizontal layers
B. In horizontal rock layers, each layer is younger than the one below it
C. Rock layers must be in existence before something can happen to them
D. Rocks that are not in horizontal layers were shifted by some geologic event.
Answer:
B. In horizontal rock layers, each layer is younger than the one below it
Explanation:
Law of superposition, a major principle of stratigraphy stating that within a sequence of layers of sedimentary rock, the oldest layer is at the base and that the layers are progressively younger with ascending order in the sequence. ... It is one of the great general principles of geology..

1.what effect does air pressure have on wind movement?
2.what happens to the density of air as it is heated
3. It’s a hot, sunny morning in a coastal town in south Florida. Warm air is rising up from the land. Large, puffy clouds are forming overhead. Which way do you think the wind will be moving this afternoon, and what do you think will happen to the temperature?
Answer: 1) Gases move from high-pressure areas to low-pressure areas. And the bigger the difference between the pressures, the faster the air will move from the high to the low pressure. That rush of air is the wind we experience. 2) So air, like most other substances, expands when heated and contracts when cooled. Because there is more space between the molecules, the air is less dense than the surrounding matter and the hot air floats upward. This is the concept used in the hot air balloons.
Explanation: 3) Now that there are large puffy clouds in the area, most of sunlight will be clocked from reaching the earth's surface. The land will cool faster than the ocean (because water has a high heat capacity and has to lose more energy to drop by a degree which will take longer than land).
Explanation:
1)Air pressure drives the creation of wind worldwide. Although it is not the only factor, differences in air pressure throughout the Earth's atmosphere lead directly to wind and influence the speed and direction of that wind. Pressure differences also affect larger weather systems like storms, even hurricanes.
2)
Heating of the earth, which in turn heats the atmosphere, is responsible for the motions and movements of the air in the atmosphere. The faster molecules move, the hotter the air. As the molecules heat and move faster, they are moving apart. So air, like most other substances, expands when heated and contracts when cooled. Because there is more space between the molecules, the air is less dense than the surrounding matter and the hot air floats upward. This is the concept used in the hot air balloons. The air is heated by the burner and the expanding air becomes less dense, causing the balloon to rise through the denser, cooler surrounding air.

Why does the starch remain present and is detected by iodine in the boiled solution?
Answer:
Amylose in starch is responsible for the formation of a deep blue color in the presence of iodine. The iodine molecule slips inside of the amylose coil. ... A blue-black color results if starch is present. If starch amylose is not present, then the color will stay orange or yellow. I hope this helps!

How do moving glaciers change the surface of the earth??? please help!!!
Answer:
Glaciers are massive bodies of ice that move across the surface of the Earth like rivers. As glaciers move they change the surface of the Earth by wearing away loose rocks and soil and depositing them somewhere else.
Explanation:
Answer:
Glaciers change the surface of the earth by causing small or large amounts of material to be pushed out of the way as the glacier slides along a path set by gravity and angle of the slope it is on.

Which of the following is not part of cell theory?
А Cells are the basic unit of life in all organisms.
B All living things come from one or more cells.
C All cells must be able to make their own food.
D All cells come from existing cells.
Answer:
c. cells must be able to make their own food
Answer:
C. All cells must be able to make their own food.
Explanation:
The other three are the cell theory. :)
But, C is NOT, so it's the answer. Most cells don't make their own food, so it isn't something that is considered part of the theory.
