Answer:
Reluctantly she pulled away, her pulse and respiration in a race.
Its function is less that of respiration than of FIG
Terrestrial plants have a gaseous interchange of oxygen and carbon dioxide which is necessary for respiration and feeding.
The least wind raises clouds of fine dust, which fill the air, render it so opaque as to obscure the noonday sun, and make respiration difficult.

Answer:
Explanation:
Percentage by mass of Nitrogen: 47%
Molar mass of Nitrogen: 14
Portion of moles of Nitrogen: 47/14 = 3.36
Percentage by mass of Oxygen: 53%
Molar mass of Oxygen: 16
Portion of moles of Oxygen: 53/16 = 3.31
3.36 : 3.31 is approximately 1 : 1 so the empirical formula is:

Explanation:
An atom X has atomic number 15,it accepts 3 electrons in other to become stable,determine the,*Number of protons of the atom. *Determine the number of electrons after accepting the electrons. *The charge on the atom before accepting electrons. *The charge on the atom after accepting electrons
Answer:
15 protons
8 electrons in valence shell after accepting 3 electrons
Neutral/no charge before accepting 3 electrons
-3 charge after accepting 3 electrons
Let’s assume the clothes in the dryer are made of cotton. Cotton is made of long chains of carbon atoms that form fibers. Determine the number of protons, neutrons, and electrons in an atom of carbon using the information on the right.
Answer:
Protons = 6
Electrons = 6
Neutrons = 6
Explanation:
Given that:
Atomic number of C = 6
Mass number of C = 12
No. of protons:
We know that atomic number is the number of protons, so:
Protons = 6
No. of electrons:
Protons = electrons so:
Electrons = 6
No. of neutrons:
= Mass number - Atomic No.
= 12 - 6
Neutrons = 6

HELP PLEASE!!! Which of the following best describes the nitrogen fixation process?(1 point) Producers convert nitrogen gas into nitrates in the soil. Producers can then absorb nitrates through their roots. Producers convert nitrogen gas into nitrates in the soil. Producers can then absorb nitrates through their roots. Producers use the energy from sunlight to fix nitrogen gas in the atmosphere. Producers can then absorb nitrogen through their leaves. Producers use the energy from sunlight to fix nitrogen gas in the atmosphere. Producers can then absorb nitrogen through their leaves. Soil bacteria convert nitrogen gas into ammonia, nitrites, and then nitrates. Nitrates are then absorbed by producers. Soil bacteria convert nitrogen gas into ammonia, nitrites, and then nitrates. Nitrates are then absorbed by producers. Consumers convert nitrogen gas into ammonia, nitrites, and then nitrates. Waste from consumers adds nitrogen to the soil, which can be used by producers.
Soil bacteria convert atmospheric nitrogen into ammonia, nitrites, and then nitrates. This nitrates are then absorbed by producers.
What is nitrogen fixation?Nitrogen fixation is a process that converts atmospheric nitrogen (N2), into available forms such as ammonia, nitrates, or nitrites to plants so that the plant can absorb it and make amino acids so we can conclude that Soil bacteria convert atmospheric nitrogen into ammonia, nitrites, and then nitrates. This nitrates are then absorbed by producers.

The more directly the sun strikes a place on earth’s surface, the more _______ the energy is and the _______ it will be. Areas that receive less direct sunlight experience colder months.
Question 1 options:
colder, less
concentrated, warmer
warmer, concentrated
less, colder
Answer:
concentrated,warmer
Explanation:
direct sunrays means that the place recieves more insolation so the energy will be more concentrated there and the place will be warmer.

acid base reaction in soil
Answer:
Acidity has the following effects on soil: It decreases the availability of plant nutrients, such as phosphorus and molybdenum, and increases the availability of some elements to toxic levels, particularly aluminium and manganese. Essential plant nutrients can also be leached below the rooting zone.
