Does the distance from earth to sun determine the seasons? please explain
Answer:
nope
Explanation:
Contrary to popular belief, the seasons are not determined by the earth's distance from the sun. The seasons are actually caused by the earth's tilted axis. Because the axis is tilted, when the Northern Hemisphere is tilted towards the sun, it's warm.

Assume that (B) is dominant and (b) is recessive: Bb mates with Bb
A. About 50% of the offspring will show the recessive trait
B. All the offspring will show the dominant trait
C. All the offspring will show the recessive trait
D. About 75% of the offspring will show the dominant trait
If B is dominant over b and Bb mates with Bb, about 75% of the offspring will show the dominant trait.
Looking at the cross:
Bb x Bb
BB Bb Bb bb
BB and Bb will show the dominant trait while only bb will show the recessive trait.
Thus, the chances of the offspring showing the dominant trait would be 3/4 or 75% while the chances of showing the recessive trait would be 1/4 or 25%

What type of evolutionary mechanism did this story show?
Allele frequencies in a population may change due to four fundamental forces of evolution: Natural Selection, Genetic Drift, Mutations and Gene Flow. Mutations are the ultimate source of new alleles in a gene pool. Two of the most relevant mechanisms of evolutionary change are: Natural Selection and Genetic Drift.
This story showed an example of convergent evolution. Convergent evolution is the process whereby organisms that are not closely related independently evolve similar traits as a result of having to adapt to similar environments or ecological niches.
What is in the story ?In this story, the two species of birds, the crows and the jays, evolved to look similar as a result of living in the same environment and competing for the same resources.
The two species evolved to look similar in order to blend in with their environment, making it difficult for predators to distinguish them from one another. This allowed them to survive and thrive in the same environment.
Therefore, This example of convergent evolution is a perfect example of how species can evolve to look similar in order to survive in the same environment. It also shows how competition for resources can drive species to evolve similar traits in order to survive.

Answer:
Tt and tt
Explanation:
To solve this just work backwards. The first box has Tt so one parent has to have T and the other t. Since the tall plant is on the top, it is T_ and t_. Next use the second box (tt). They are both t so the final answer is Tt x tt.

The New Orleans Musicians' Clinic did not make any recommendations about low or high pitch sounds. Why are high pitch sounds less damaging to ears than louder sounds? Use your model and what you have learned about sound waves and energy to write an explanation. Some helpful words to include in your response are: transfer, energy, eardrum, and air particles.
Answer:
Due to high energy.
Explanation:
High pitch sounds less damaging to ears than louder sounds because louder sounds contains more energy than high pitch sound. When this high energy of loud sound transfer from air particles towards our eardrum, it can greatly damaged the ear while on the other hand, high pitch sound has low energy so it causes less damaged to the eardrum.

Answer:
Photosynthesis converts Light and chemical energy in to food-energy molecule sugar and gives off Oxygen
Explanation:
6CO2 + 6H2O → C6H12O6 + 6O2
Photosynthesis is a chemical reaction that takes place inside a plant, producing food for the plant to survive.
Carbon dioxide, water and light are all needed for photosynthesis to take place.

Answer:
The Cell Wall of Bacteria
Bacteria are protected by a rigid cell wall composed of peptidoglycans.
LEARNING OBJECTIVES
Recall the characteristics of a bacterial cell wall
KEY TAKEAWAYS
Key Points
A cell wall is a layer located outside the cell membrane found in plants, fungi, bacteria, algae, and archaea.
A peptidoglycan cell wall composed of disaccharides and amino acids gives bacteria structural support.
The bacterial cell wall is often a target for antibiotic treatment.
Key Terms

Bacterial Cell Wall: The anatomy of bacterial cell structure.
Bacterial cells lack a membrane bound nucleus. Their genetic material is naked within the cytoplasm. Ribosomes are their only type of organelle. The term “nucleoid” refers to the region of the cytoplasm where chromosomal DNA is located, usually a singular, circular chromosome. Bacteria are usually single-celled, except when they exist in colonies. These ancestral cells reproduce by means of binary fission, duplicating their genetic material and then essentially splitting to form two daughter cells identical to the parent. A wall located outside the cell membrane provides the cell support, and protection against mechanical stress or damage from osmotic rupture and lysis. The major component of the bacterial cell wall is peptidoglycan or murein. This rigid structure of peptidoglycan, specific only to prokaryotes, gives the cell shape and surrounds the cytoplasmic membrane. Peptidoglycan is a huge polymer of disaccharides (glycan) cross-linked by short chains of identical amino acids (peptides) monomers. The backbone of the peptidoglycan molecule is composed of two derivatives of glucose: N-acetylglucosamine (NAG) and N-acetlymuramic acid (NAM) with a pentapeptide coming off NAM and varying slightly among bacteria. The NAG and NAM strands are synthesized in the cytosol of the bacteria. They are connected by inter-peptide bridges. They are transported across the cytoplasmic membrane by a carrier molecule called bactoprenol. From the peptidoglycan inwards all bacterial cells are very similar. Going further out, the bacterial world divides into two major classes: Gram positive (Gram +) and Gram negative (Gram -). The cell wall provides important ligands for adherence and receptor sites for viruses or antibiotics.

4. What best describes the role of mutations in evolution?
a. Mutations are not necessary for evolution because they are not herita
b. Mutations are useful for evolution to occur because they promote ger
uniformity within a population.
c. Mutations are essential for evolution to occur because they produce
variations within a population.
d. Mutations are essential for evolution to occur because they are respo
environmental changes.
Answer: option C.
Mutations are essential for evolution to occur because they produce variations within a population.
Explanation:
This is because Mutation refer to change in the genetic content or DNA composition of organisms. Therefore , for evolution to occur there must be Mutation because it is the main source of genetic variation or causes genetic variation needed for evolution.
Mutation is important as the basics of evolution because it produce a new DNA sequence for a gene function, which lead to the formation of new allele.
