The respiratory system is lined with a tissue layer known as the mucous membrane. We discussed how this layer helps to alter the incoming air in three important, beneficial ways. Explain the three ways the mucous membranes alter the incoming air and the benefit of each of these alterations
Warming, add moisture and trap depris are the three ways the mucous membranes alter the incoming air.
Role of mucous in breathingNasal mucous membranes are lined with small blood vessels that help to warm as well as humidify the air you breathe. They are also lined with cilia which is a tiny hair-like structures that help to trap the debris that you breathe in during inhalation.
So we can conclude that warming, add moisture and trap depris are the three ways the mucous membranes alter the incoming air.

Which statement describes one way that roots and leaves interact to transport water through plants?
The flow of oxygen out of the stomata of leaves
stimulates the roots to absorb more water for
photosynthesis.
Wilting leaves send chemical signals to the roots,
causing them to take in water at a faster rate.
The evaporation of water through the stomata of
leaves creates a pull that draws water in through the
roots.
Changes in sugar concentration in the phloem of
leaves causes water to move into the roots by
osmosis.
The statement that describes one way that roots and leaves interact to transport water through plants is: evaporation of water through the stomata of leaves creates a pull that draws water in through the roots.
What is transpiration?Transpiration is the process whereby water is lost from the surface of the leaf into the atmosphere.
A process called transpiration pull facilitates the absorption of water by the root hairs of the plant.
The water then moves via the conducting vessel called xylem to other parts of the plant.
Therefore, the statement that describes one way that roots and leaves interact to transport water through plants is: evaporation of water through the stomata of leaves creates a pull that draws water in through the roots.

During cell polarization, what are the two resultant edges called?
Answer:
The leading and trailing edge
Explanation:
Cutting the front edge of each wave's half cycle using leading edge dimming. Trailing edge dimming, on the other hand, eliminates the second half of each wave's half cycle.
~
During cell polarization, the two resultant edges are called the leading edge and the trailing edge.
What do you mean by Cell polarization?Cell polarization may be defined as a phenomenon by which cytoskeletal arrangement, extra- and intracellular signals, and organelle and membrane reorganization occur due to maintaining the cell shape.
Leading-edge works on the front edge and separates the half-wave cycle, while the trailing edge works on the back edge and cuts the second half of the wave.
Therefore, during cell polarization, the two resultant edges are called the leading edge and the trailing edge.

How can we stop carbon dioxide to the ocean to not affect pH levels?
Answer:
Because of human-driven increased levels of carbon dioxide in the atmosphere, there is more CO2 dissolving into the ocean. The ocean's average pH is now around 8.1 , which is basic (or alkaline), but as the ocean continues to absorb more CO2, the pH decreases and the ocean becomes more acidic.
Hope This Helps
Answer:
Carbon dioxide (chemical formula CO2) is a chemical compound occurring as an acidic colorless gas with a density about 53% higher than that of dry air. Carbon dioxide molecules consist of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth's atmosphere as a trace gas. The current concentration is about 0.04% (412 ppm) by volume, having risen from pre-industrial levels of 280 ppm.[9][10] Natural sources include volcanoes, forest fires, hot springs, and geysers, and it is freed from carbonate rocks by dissolution in water and acids. Because carbon dioxide is soluble in water, it occurs naturally in groundwater, rivers and lakes, ice caps, glaciers, and seawater. It is present in deposits of petroleum and natural gas. Carbon dioxide has a sharp and acidic odor and generates the taste of soda water in the mouth,[11] but at normally encountered concentrations it is odorless.[1]

A cement factory emits 900 kilograms of CO2 to produce 1,000 kilograms of cement. A fully grown tree removes six kilograms of CO2 per day from the air. One acre of land can support 200 mature trees.
A company builds a factory that will produce 100,000 kilograms of cement. To make the factory carbon neutral, the owners need to grow
trees over an area of land measuring
acres.
Answer: To make the factory carbon neutral, the owners need to grow 15000 trees over an area of land measuring 75 acres
Explanation:
From the information;
900 kg CO2 = 1000 kg Cement
1 tree = 6 kg CO2
1 acre = 200 trees
100000 kg Cement will require;
=(900 × 100000)/1000
= 90,000 kg of CO2
But 1 tree = 6 kg of CO2
Number of trees = 90,000/6
= 15,000 trees
But, 1 acre = 200 trees
Number of acres = 15,000/200
= 75 acres of land
Therefore;
To make the factory carbon neutral, the owners need to grow 15000 trees over an area of land measuring 75 acres

Severe flooding in an area caused a population of minnows to become split into two separate ponds. Prior to the separation, the male minnows all had a moderate number of spots.
Following the separation, the first pond was filled with larger fish that fed on minnows, so male minnows with fewer spots were better able to avoid detection by predators. The minnows in the second pond, however, had very few predators, and female minnows in this pond preferred to mate with males that had the most spots.
After many generations, the two minnow populations evolved into different species and could no longer interbreed.
Fish Species Average # of Spots
Original Species four to six
New Species 1 zero to two
New Species 2 eight to ten
Which of the following best describes why the two minnow populations evolved into separate species?
A.
Natural selection acted upon the traits of the minnows in the first pond only, causing these fish to evolve into a new species with new adaptations.
B.
Natural selection acted upon the traits of the minnows in the second pond only, causing these fish to evolve into a new species with new adaptations.
C.
The same selective pressures were acting upon both populations, leading to a decrease in genetic variation and the formation of two new species.
D.
Different selective pressures were acting upon the two populations, leading to an increase in genetic variation and the formation of two new species.
