Lab 9: Kingdom Plantae (12 Points) Introduction Plants are defined as multicellular eukaryotes with cell walls made of cellulose. Nearly all of them contain chlorophyll and carry out photosynthesis. Being photoautotrophs, plants can make all their own organic molecules. All they need is energy from light, carbon from carbon dioxide, water, and various elements (like N, P, K, Ca, and Mg). Water can be absorbed into a plant by osmosis, but it can only travel a few cells away from a source. In order to transport water long distances, some groups of plants have specialized tissues (vascular tissue). Plants without vascular tissues must live in wet areas and cannot grow very tall. Consult the plant lecture, slides, and links on Canvas for more information on defining features of plants and groups of plants. Part 1: Comparing major groups of plants Within the plant kingdom, biologists separate plants into four major groups: bryophytes (mosses and llverworts), pteridophytes (ferns), gymnosperms (conifers), and anglosperms (flowering plants). The separations are primarily based on anatomical structures, particularly the ones they use to transport water in their bodies, and on the different ways in which plants reproduce sexually. **What to submit for this activity** Use the information from lectures, the textbook, and any other sources of your choice to fill out the table comparing the four major groups of plants. Submit your completed table as part of what you upload to the Canvas lab assignment for this week. (5 Points) What are one or more examples? Do they have vascular tissue (xylem and phloem)?

The speed of sound in steel is greater than it is in air because
steel is
a. more elastic than air
b. less elastic than air
c. more dense than air
d. less dense than air
The speed of sound in steel is greater than it is in air because
steel is
a. more elastic than air
b. less elastic than air
c. more dense than air
d. less dense than air
Answer:
Option A
Explanation:
The more elasticity the medium has, the more speed the sound travels. The density of steel is more than air because molecules are closer together in solids than in liquids or gas.
In general, sound waves in steel travel 17 times faster than through air. The speed of sound is determined by the dynamic propagation of sound waves. The speed of sound depends on elasticity and density and here both the elasticity and density of steel are more than air.
Hence, "The speed of sound in steel is greater than it is in the air because steel is more elastic than air".

Dertemine the maximum volume of the air breathed in during the period of rest for each minute
The maximum volume of air breathed in during the period of rest for each minute is 500 ml also known as tidal volume.
Tidal volume is simply each breath a person takes. It is a significant factor in both minute and alveolar ventilation. The quantity of air that enters the lungs each minute is measured by minute ventilation also referred to as total ventilation. It is a function of both tidal volume and respiratory rate.
A physiological term called tidal volume (Vt or TV) is used to indicate how much air is generally moved during inspiration and expiration when you are at rest. Spirometry, a non-invasive test, is used to measure it. Adults breathe on average seven milliliters (mL) every kilogram (kg) of ideal body weight.
When it comes to configuring the ventilator in critically ill patients, tidal volume is crucial. Delivering a tidal volume that is both large enough to sustain proper breathing and small enough to prevent lung trauma is the objective.

weather. Ferret habitats largely coincided with the habitats of the black-tailed prairie dog (C. ludovicianus), Gunnison's prairie dog (C. gunnisoni),
and the white-tailed prairie dog (C. leucurus). Despite significant recovery successes over the last decade, the black-footed ferret remains one of
the most endangered animals in the world.

B. increased disease and death among prairie dog populations.
C. continued increase in the human population.
D. habitat destruction of the three prairie dog species.
E. conversion of grassland to agricultural land.

Which abiotic factor in tropical forests do boreal forests lack?
Answer:
warm temperature
Explanation:
I cannot see the choices in your image. I can only see choice A, which is "soil."
"Abiotic factors" are part of the ecosystem that don't have life. However, they have an impact on the life of the biotic factors (living organisms) in the environment. Examples of abiotic factors are: sunlight, temperature, climate, soil, humidity, wind, etc.
"Boreal forests" are abundant on the Earth's Northern Hemisphere. The climate here is generally cold, which doesn't allow some trees to survive. It is totally opposite to the warm temperature and high humidity that you can feel in the "tropical forests." Such factors allow many plants and animals to survive.
Clearly, the boreal forests lack the "warm temperature" that the tropical forests have.

Deforestation and the burning of fossil fuels such as coal and oil have led to higher concentrations of carbon dioxide in the atmosphere
Deforestation and the burning of fossil fuels such as coal and oil, are the two main causes of higher concentrations of carbon dioxide in the atmosphere.
The statement "Deforestation and the burning of fossil fuels such as coal and oil have led to higher concentrations of carbon dioxide in the atmosphere" refers to the fact that human activities have significantly increased the amount of carbon dioxide in the atmosphere, leading to a rise in global temperatures and climate change.
Deforestation contributes to this problem by reducing the amount of trees that absorb carbon dioxide during photosynthesis, while the burning of fossil fuels releases stored carbon into the atmosphere. These actions have negative impacts on the environment, including increased global temperatures, rising sea levels, and more frequent extreme weather events.
