Answer:
Nose or nasal cavity, oral cavity or mouth, pharynx,larynx, wind pipe i.e both left and right bronchi, bronchioles, alveoli and lungs.
Explanation:
Air which contain oxygen pass through the nasal cavity, it then move to the pharynx or mouth, through the glottis. The air or oxygen then pass through trachea or windpipe and move to the left and right bronchi, it then move to the alveoli which is the site of gas exchange. Oxygen is absorbed into the blood and the carbondioxide is removed from the blood through the lungs.

These two birds both chirp a song in the morning. Compare and contrast the two
waves properties (wavelength, amplitude, frequency). Finally determine which bird's
sound wave has more energy and why?
EM .
Include the following terms in your answer:
• Frequency
• Amplitude
• Long Wavelength
. Short Wavelength
• Higher energy
• Lower energy
Answer:
Sound wave that have more energy are louder and have more frequency, amplitude and short wavelength
Explanation:
That bird's sound wave has more energy which has higher frequency of sound. Due to its higher frequency of sound, the amplitude is also higher. That sound which have higher frequency has short wavelength and those sounds which has lower frequency and pitch has long wavelength. So we can say that sound wave that have more energy are louder and have more frequency, amplitude and short wavelength whereas sound wave that have lower energy are less louder and have less frequency, amplitude and long wavelength
b. What structure holds the two sister chromatids together in the middle as they

Where does energy first come into an ecosystem?
A producers make energy
B the sunlight provides energy to producers
C consumers obtain energy from animals
D scavengers obtain energy from dead plants
Answer:B. Sunlight provides energy to producers
Explanation: photoautotrophs (plants) produce energy from sunlight by photosynthesis. This is the only energy production based on an external source of energy. Plants, whether alive or dead, are consumed by heterotrophs - bacteria, fungi and animals. The nutrients and energy from dead heterotrophs (and some live ones) are recycled by both autotrophs and heterotrophs.

by what method do the gases oxygen and carbon dioxide pass into or out of the bloodstream?
Answer:
DIFFUSION
Explanation:
The oxygen in inhaled air passes across the thin lining of the air sacs and into the blood vessels. This is known as diffusion. The oxygen in the blood is then carried around the body in the bloodstream, reaching every cell. When oxygen passes into the bloodstream, carbon dioxide leaves it.

Where does the energy for most ecosystems originate? How is this converted into the energy in food?
Answer:
Explanation:
"Energy is transferred between organisms in food webs from producers to consumers. The energy is used by organisms to carry out complex tasks. The vast majority of energy that exists in food webs originates from the sun and is converted (transformed) into chemical energy by the process of photosynthesis in plants."

2. What attaches to the DNA and exposes the nucleotides on the two strands?
Answer:After the primer is in place on a single, unwound polynucleotide strand, DNA polymerase wraps itself around that strand, and it attaches new nucleotides to the exposed nitrogenous bases.
Explanation:
Answer:
The two strands of DNA helix are unwind and separated. The RNA polymerase, a special type of enzyme travels along the strands of DNA and binds RNA nucleotides to it until it forms a complete strand of messenger RNA. The messenger RNA also known as mRNA is the cell’s blueprint, which is used to construct a specific type of protein.
