Answer:
Rate and tidal volume
Explanation:
Tidal volume is the volume of air moved in or out of the lungs with each normal breath. A normal tidal volume is around 500 to 600 mL per inspiration and/or 6 to 7 mL per kilogram of body mass. An Emergency Medical Technician (EMT) should assess the respiratory rate (as well as rhythm and quality), having into account that a normal respiratory rate in an adult is 12 to 18 breaths per minute (BPM). Moreover, an appropriate tidal volume is also fundamental in assisting individuals in respiratory distress and arrest.
how would hemoglobin content differ in a person living in philadelphia compared to someone living in denver
Answer:
The correct answer is - the difference in altitudes.
Explanation:
The hemoglobin in the person of Denver who lives at a higher altitude than the person who lives in Philadelphia will be much higher. This is due to the fact that at higher elevation or altitude atmospheric pressure decreases that causes hemoglobin to stick to the RBCs and that results in less oxygen level in the body.
To compensate for this low level of oxygen levels hemoglobin content need to be higher in people living at a higher elevation.

In the Punnett square fill in the shaded boxes with the alleles of each parent use B for the dominant allele (black fur) and b for the recessive allele (white fur)
Answer:
Explanation:
Under the male put BB
Next to the female bb
then first row should be Bb Bb
second row should Bb Bb
Here, all the alleles of the black parent are dominant and are represented as BB, and those of the white parent are represented as bb, and they both are purebred dominant and recessive alleles that have produced all dominant black (Bb) offspring.
What is Punnett Square?A Punnett square is a diagram used to predict the possible outcomes of a genetic cross between two parents. In this case, the parents have different alleles for a gene that determines the color of their fur. The dominant allele B produces black fur, while the recessive allele b produces white fur. The Punnett square is arranged in a grid, with each box representing one possible genotype for the offspring. The top row and left-hand column of the grid represent the alleles that each parent can contribute to their offspring. In this case, both parents are purebred,as expressed below.
Hence, black parents are dominant and are represented as BB, and those of the white parent are represented as bb, and have produced all dominant black offspring.

Most autotrophs use a process called photosynthesis to make their food. In photosynthesis, autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into a nutrient called glucose.
list few points on the importance of sun in power supply.
Answer:
The sun provides more than enough energy to meet the whole world's energy needs, and unlike fossil fuels, it won't run out anytime soon. As a renewable energy source, the only limitation of solar power is our ability to turn it into electricity in an efficient and cost-effective way.
Answer:
Nothing is more important to us on Earth than the Sun. Without the Sun's heat and light, the Earth would be a lifeless ball of ice-coated rock. The Sun warms our seas, stirs our atmosphere, generates our weather patterns, and gives energy to the growing green plants that provide the food and oxygen for life on Earth.

Large biomolecules and macromolecules known as proteins are made up of one or more extended chains of amino acid residues. Proteins are responsible for the structures and functions of organisms.
What is Protein?Large, intricate molecules classified as proteins perform an array of essential roles in the human body. They are fundamental for the structure, operation, and control of the body's tissues and organs and perform out the majority of their work inside cells.
Many thousands of amino acids, which seem to be smaller components that make up proteins, are linked together in lengthy chains to form proteins. To form a protein, 20 different kinds of amino acids can be mixed. Each protein's precise function and characteristic 3-dimensional structure are established by its amino acid sequence.
Thus, Proteins are responsible for the structures and functions of organisms.

Answer:
Cerebral cortex.
Explanation:
The masses of gray matter that lie deep within the cerebral hemispheres is called cerebral cortex. The cerebral cortex is responsible for many brain functions such as sensation, perception, memory, association, thought, and voluntary physical action. Damage occur to cerebral cortex can leads to many cognitive, sensory, and emotional difficulties in the body. It is also responsible for regulating intensity and precision of voluntary movement.

The discovery of a buried crater (about 200 km across) near Chicxulub, Mexico.
What is extinction?
Extinction is defined as the disappearance of an organism or a group of organisms as a result of environmental factors or changes in the members' evolutionary processes.
It can also be defined as an evolutionary process that causes a species or population to go extinct.
When there are no longer any living members of a certain animal or plant species anywhere in the globe, the species has become extinct.
Generally speaking, species disappear for the following reasons:
Genetic and demographic phenomena.Habitat destruction in the wild.Species introduction that are invasive.Global warmingHunting and illicit trade.Thus the discovery of a buried crater (about 200 km across) near Chicxulub, Mexico.

Why has the number of people in the world increased if the human population growth rate has decreased?
Answer:
Life expectancy has steadily risen.
People live longer lives.
To understand the reasons why the number of people in the world has increased and the population growth rate has decreased, it is necessary to understand how the world's demographic growth rate is calculated.
The calculation is made from the balance between the total number of people alive and the total number of deaths that occurred in a period of time.
Therefore, we can understand that the population growth rate has decreased due to several relevant factors, such as:
Increased life expectancy.The decrease in infant mortality.Rising fertility rates.Urbanization.Economic development.These are some of the reasons that help us understand why population numbers increase and population growth rate decreases.
Economic development, new technologies and a better quality of life for the population are directly related to the decrease in the population growth rate.

which type of hormone diffuses across the plasma membrane and binds to receptors in the cytoplasm module 16.4c
Answer:
Steroid hormones.
Explanation:
Steroid hormones is a type of hormones that diffuses across the plasma membrane and binds to the receptors present in the cytoplasm. The hormones are released from the carrier protein and diffuse inside the cell across the lipid bilayer of the plasma membrane of the cells. The steroid hormones pass through the plasma membrane of a target cell and attached to the intracellular receptors located in the cytoplasm or in the nucleus.

Some broad-spectrum proteases (protein hydrolyzing enzymes) and nucleases (nucleic acid hydrolyzing enzymes) that function in eukaryotic cells have an optimum pH close to 5.0, whereas the cytosol of most cells is closer to pH 7.0. Which part of a eukaryotic cell might you predict to have a low pH suited to maximizing the activity of these enzymes
Answer:
lysosome
Explanation:
The lysosome is a membrane-bound organelle found in nearly all eukaryotic cells. The lysosome contains different types of enzymes (i.e., proteases, nucleases, glycosidases, lipases, phosphatases) which are required for the digestion of macromolecules and microorganisms, and recycle macromolecules in the cell. These enzymes are only active in acidic (lysosome) conditions, and they can be deactivated in case of lysosomal rupture because in the cytosol the pH is neutral to slightly alkaline (∼7.3–7.4).
