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)?

In order to measure the absorption spectrum of CoCl2, you need to dilute the stock solution to 0.32 M. What volume of the stock solution (0.8 M concentration) and water should be mixed to make a 10 mL solution of 0.32 M?
Answers
Explanation:
Volume of stock solution needed
= 10mL * (0.32M/0.8M)
= 10mL * (4/10) = 4mL.
Volume of water needed
= 10mL - Volume of stock solution
= 10mL - 4mL = 6mL.
The volume of water needed in this case will be equal to 6 ml.
What is the stock solution?To make a stock solution, weigh out the proper amount of a pure solid or measure out the proper amount of a pure liquid, put it in the right flask, and then dilute it to the desired volume. Depending on the intended concentration unit, many methods can be used to measure the reagent.
For instance, to make a solution with specified molarity, you weigh out the proper mass of the reagent, mix it with some solvent, and then add enough liquid to make the necessary volume. You measure out the right amount of solute and add enough solvent to get the right total volume to create a solution where the solute concentration is expressed as a volume percent.
A highly concentrated stock solution is frequently diluted to create solutions. The stock solution is moved to a new vessel and produced to a new volume at a known volume.
Here,
The volume of stock solution needed
= 10mL × (0.32M/0.8M)
= 10mL × (4/10) = 4mL.
The volume of water needed
= 10mL - Volume of stock solution
= 10mL - 4mL = 6mL.
Therefore the volume of water needed here is equal to 6 ml.

Will the trend toward an increased incidence of tusklessness in a population with heavy poaching lead to increased African elephant population sizes in the future?
Answers
No, the trend toward increased tusklessness in African elephants due to heavy poaching is not likely to lead to increased population sizes in the future.
While tuskless elephants may have a survival advantage in areas with high levels of poaching, this advantage is likely to be temporary. Over the long term, tusklessness may lead to reduced genetic diversity and reproductive success, as tusks play a role in mate selection and competition among males.
Additionally, tuskless elephants may be less able to defend themselves and their young against predators and may have a reduced ability to forage for food. Thus, while tusklessness may confer some immediate benefits in areas with high levels of poaching, it is not a viable long-term solution for elephant populations.

explain why meiosis is referred to as a random process while mitosis is a homeostatic process
Answers
Answer:
Meiosis is referred to as a random process because during this process, the genetic material of the parent cell is randomly divided and distributed among the daughter cells. This means that the daughter cells created are not exact replicas of the parent cells and have different genetic makeups. This is why meiosis is referred to as a random process.
Mitosis, on the other hand, is referred to as a homeostatic process because during this process, the genetic material of the parent cell is replicated exactly and distributed among the daughter cells. This means that the daughter cells created are exact replicas of the parent cells and have the same genetic makeup. This is why mitosis is referred to as a homeostatic process.

how do you think the intake of nutrients and expenditure of energy relate to a metabolic level
Answers
The intake of nutrients and expenditure of energy relate to a metabolic level is the rate at which the body converts food into energy.
When we consume food, the body breaks it down into smaller molecules that can be used for energy. This process is called digestion and it requires energy.
The nutrients from the food we eat are then transported to cells throughout the body where they are used to fuel cellular processes, such as muscle contraction and brain function.
The body's metabolic rate is influenced by the type and amount of nutrients consumed. For example, consuming carbohydrates and proteins increases metabolic rate more than consuming fat.
This is because carbohydrates and proteins require more energy to digest and absorb than fat.
Additionally, the expenditure of energy through physical activity can also influence metabolic rate. Regular exercise increases muscle mass, which requires more energy to maintain than fat tissue.
This means that individuals with more muscle mass have a higher metabolic rate than those with less muscle mass, even at rest.
Overall, the intake of nutrients and expenditure of energy are closely related to metabolic rate, and maintaining a balanced diet and regular physical activity can help to optimize metabolic function.

How do thermouses know whether or not to keep food hot or cold?
Answers
Answer:
A thermos keeps cold things cold in the same way. It doesn't contain some kind of cooling device. The same vacuum that keeps hot things hot keeps cold things cold. Heat that might otherwise transfer to the cold contents of the thermos is prevented from reaching it because of the vacuum between the thermos walls.
Today's thermoses are constructed much more sturdily than those in the past. The first thermoses featured metal exteriors with glass interior walls. These thermoses often ended up getting broken when accidentally dropped.

What is the flexibility of spider silk determined by the structure of its molecules
Answers
The flexibility of spider silk determined by the structure of its molecules is quite strong.
The components that make up spider silk are what give it its flexibility. Proteins called fibroins, which are made up of amino acids organised in a certain sequence, make up spider silk. The arrangement of amino acids in fibroin proteins results in a helical structure, which is held together by hydrogen bonds between the amino acids.
The fibroin protein chain's exact arrangement of amino acids and hydrogen bonds produces a special blend of strength and flexibility. The silk is flexible enough to stretch and absorb energy without breaking and robust enough to resist significant stress. Spider silk is a fantastic material for many uses, including clothes, medical equipment, and even bulletproof vests, thanks to its unique mix of qualities.

What are the two features of molecules that can undergo simple diffusion?
Answers
Answer:
This type of diffusion proceeds without an input of energy. In simple diffusion, molecules that are small and uncharged can freely diffuse across a cell membrane. They simply flow through the cell membrane. Simple diffusion does not require energy or need the assistance of a transport protein.
Explanation:
Answer:
simple diffusion is the process by which solutes are moved along a concentration gradient in a solution or across a semipermeable membrane. Simple diffusion is carried out by the actions of hydrogen bonds forming between water molecules and solutes. Water molecules move in to surround individual solute molecules, which maximizes hydrogen bonding. Hydrogen bonds are extremely temporary, however, and the solution is constantly stirred as a result.
