A nurse is assessing a newborn in the well baby nursery. what type of respirations does the nurse expect to identify in a healthy newborn?
Answer:
Due to the shape of the airway, babies breathe almost completely through their noses and at a much faster rate than adults. If mom and dad breathe between 16 and 20 times per minute, the newborn breathes three times faster, reaching values between 40 and 60 times per minute.

All organisms require nitrogen to make amino acids, which in turn are used to build carbohydrates
Final answer:
Organisms require nitrogen to synthesize amino acids, the building blocks of proteins, not carbohydrates. Nitrogen fixation by microorganisms converts atmospheric nitrogen into forms usable by plants, which animals then consume, making it a critical component of the nitrogen cycle.
Explanation:
The original statement that all organisms require nitrogen to make amino acids, which in turn are used to build carbohydrates, contains an error. In fact, organisms use nitrogen to synthesize amino acids, which are the building blocks of proteins, rather than carbohydrates. Atmospheric nitrogen (N2), which makes up about 79% of Earth's atmosphere, cannot be utilized directly by most organisms. Through a process called nitrogen fixation, certain microorganisms convert atmospheric nitrogen into forms that plants can absorb, such as nitrate ions (NO3−) and ammonium ions (NH4+). Once assimilated by plants, these nitrogen compounds can be incorporated into amino acids and eventually proteins. Animals obtain their nitrogen by consuming plants or other animals. The cycling of nitrogen between the atmosphere, soil, plants, and animals is an integral part of the nitrogen cycle, which is crucial for life on Earth.
3 reasons why determining cause of death can be difficult
When you spin around, you lose balance because of fluid spinning around in the _____. A. cochlea B. tympanic membrane C. semicircular canals D. auricle
Answer: Semi circular canals.
Explanation: These are three fluid filled canals located in the inner ear that is helps us to maintain the balance.
When the head is moved around, the fluid moves the hair inside and these tiny hair sens the message to the nerve cell ( brain).
But when you move around the liquid keeps on sending the message to the brain that you are moving a bit longer and the body loses its balance.

In the desert food web shown below, which of the following best describes the transfer of energy between the desert tortoise and the coyote?
A) About 90 percent of the desert tortoise's energy transfers to the coyote.
B) About 10 percent of the coyote's energy transfers to the desert tortoise.
C) About 10 percent of the desert tortoise's energy transfers to the coyote.
D) About 90 percent of the coyote's energy transfers to the desert tortoise.
Answer:
C) About 10 percent of the desert tortoise's energy transfers to the coyote.
Explanation:
In the given food web, the coyote is the top consumer that feeds on desert tortoise and kangaroo rat. Only 10% of the energy of one trophic level is passed to the next trophic level and 90 % of the energy is lost in respiration.
Hence, only 10% energy of desert tortoise would be delivered to coyote and rest would be lost during respiration.
Which statement correctly describes the bars on a bar graph representing the data?
The right answer is C.
A bar chart, also known as bar graph or column diagram, is a way to graphically represent a set of data or values, and is made up of rectangular bars of lengths proportional to the values represented. Bar graphs are used to compare two or more values. The bars can be oriented horizontally or vertically.
Since the value obtained at very low concentration (30) is twice the value obtained at average concentration (15), it can be deduced that "C" is a correct answer. The other answers are false.
Which femoral structure is located at the distal end of the medial supracondylar ridge?
Final answer:
The adductor tubercle is the femoral structure found at the distal end of the medial supracondylar ridge, serving as an attachment point for the adductor magnus muscle.
Explanation:
Femoral Structure at the Distal End of Medial Supracondylar Ridge
The femoral structure located at the distal end of the medial supracondylar ridge of the femur is known as the adductor tubercle. This small protrusion is found on the medial condyle and serves as the point of attachment for the adductor magnus muscle. The medial epicondyle of the femur is a roughened area on the distal femur located on the medial side of the medial condyle, just above the adductor tubercle. The medial supracondylar ridge is a bony ridge that extends from the adductor tubercle down the shaft of the femur. The structures of the distal end of the femur, including the medial and lateral condyles, the epicondyles, and the patellar surface, articulate with the tibia to form the knee joint and provide attachment points for muscles and supporting ligaments.
How many amino acids are affected by a change in one nitrogen base?answer?
It changes one amino acid in the genetic code if a change in one nitrogen base occurs because one triplet codon is responsible to make one amino acid.
What is genetic code?DNA is the genetic material that stores information about the organism, this information is first converted into RNA by the process of transcription. After the transcription, this information is converted into the amino acid sequence.
Genetic code is the triplet sequence of a nitrogen base, which codes for the protein if any base is changed with another base, it will change the amino acid. Amino acid is made by triplet code, three bases are responsible for one amino acid.
Therefore, one amino acid is affected by a change in one nitrogen base, due to a triplet genetic codon.

It is crucial that the process of mitosis is error free. This is because otherwise healthy cells can
The right answer is Become cancer cells.
To multiply constantly, cancer cells bypass many regulations of cell proliferation, which leads them to proliferate uncontrollably. These cells have several solutions to prevent senescence.
In a healthy situation, a cell needs growth factors to proliferate. In a cancerous situation, the cancer cell can mutate an oncogene so that it permanently generates proliferation signals, regardless of the presence of growth factors.
For a cell to proliferate, the critical point it must pass through the cell cycle is the restriction point maintained by the Rb protein. Proliferation signals must be sustained to inactivate this control point as the rest of the cell cycle progresses without external stimulation. To proliferate excessively, the cancer cells thus overactivate the cell proliferation signals to pass the restriction point as quickly as possible. They use several strategies to over-activate these signals.
Which method of collecting data would provide the most accurate information about how an ecosystem is being affected by human development?
The people in the neighborhood record the number of birds they see in the area both before and after the constructions of a new building.
Deer in the area are identified before construction so that scientists can see where they go after the building is finished.
More trees are planted in the area around the construction site to allow the animals a new place to live.
The population size is recorded for each species present in the construction area before and after the building is completed.

Uncovered lightbulbs may expose food to which type of hazard ?
Answer:
Physical Hazard
Explanation:
An hazard is defined as something or a substance that by itself or due to its interaction or combination with another substance has the potential to cause harm.
We have 3 types of hazards.
a. Physical Hazard: This has to do with substances such as: uncovered light bulbs
b. Chemical Hazard: This has to do with chemical substances e.g. Acids, Bases, Pesticides, radioactive substances, e.t.c.
c. Biological Hazard: For example microorganisms such as Viruses, Bacteria and Fungi
Uncovered light bulbs may expose foods to physical hazard such as if the light bulbs get shattered , the presence of broken light bulb shards in food is very harmful.

Predict the likely effect of continued deforestation on plant and animal life.
As it well known fact that 70-80% of the plants and land animals live in forest, continuous deforestation may lead to threatening of various species. Large number of trees in forest help by blocking the sun ray's during the day and by retaining the heat during night. Deforestation would lead to disruption of such phenomenon further leading to extreme temperatures harming the plants and animals.
If photosynthesis captures only 1-2% of the energy from sunlight, what happens to the other 98-99% of energy
Final answer:
During photosynthesis, only 1-2% of the energy from sunlight is captured and converted into chemical energy by plants. The remaining 98-99% of the energy is not utilized by photosynthesis and is dissipated into the environment.
Explanation:
During photosynthesis, only 1-2% of the energy from sunlight is captured and converted into chemical energy by plants. The remaining 98-99% of the energy is not utilized by photosynthesis and is either reflected or absorbed by the surroundings. This excess energy can be in the form of heat and is dissipated into the environment. It does not contribute directly to the process of photosynthesis.
