When we extracted our own DNA last Friday, how did the things we used (Gatorade, alcohol, soap) relate to the things that are used in this virtual lab?
Answer:
Soap solution functions to dissolve the cell membranes, alcohol is used to precipitate DNA, and Gatorade is a isotonic solution.
Explanation:
In the DNA extraction protocols, the cell membranes that are formed by lipidic bilayers can be dissolved by using detergent solutions that are functionally analog to soap solution, shampoo, etc. On the other hand, alcohol enables to precipitate DNA (because DNA is not soluble in alcohol), while proteins and other cellular components remain in the extraction solution. Finally, Gatorade is a isotonic solution that may be used to prevent the cells from lysing.
A carrot would be an example of a _______ system. The apical meristem and new growth in the roots are protected by the _______. Stems of _______ contain a ring of vascular tissue, which includes the xylem and phloem. Stems thicken to support plants growing taller during _______ growth. _______ regulate the exchange of gases in the leaves and help maintain homeostasis. The leaves are often broad and flat because they are the main site of _______ in a plant. The force that allows water molecules to stick to other water molecules is called _______. The process by which plants release water into the air as vapor, while pulling more water upward into the leaves is called _______. Respond to the following based on your reading. Explain, in your own words, the role of cohesion and adhesion in plant transpiration. What are several adaptations that leaves have undergone? Why do leaves have adaptations in different parts of the world? Choose three nutrients and explain how a plant may look if it has a deficiency in those nutrients.
Answer:
taproot
root cap
dicot
secondary
Stomata
photosynthesis
cohesion
transpiration
Cohesion describes water molecules sticking together, while adhesion allows them to stick to the sides of the xylem that runs up the plant stem. When water at the top of this chain breaks free and evaporates from the leaf, it pulls on the water molecules behind it. In this way, water molecules are pulled up the plant stem from the roots and into the leaves.
Leaves have adaptations such as broad or narrow widths, rounded or pointy tips, and straight versus many vertices. These adaptations allow different species of plants to optimize water retention and photosynthesis in different climates (in other words, cloudy, sunny, rainy, dry).
Answers will vary based on the three nutrients selected. Here is a model response: Plants can show many different deficiencies based on their nutrients. An iron deficiency will result in yellowing or brittle leaves. A potassium deficiency causes leaves to turn yellow at the edges and phosphate deficiencies cause plants to have darker green than normal leaves.
Explanation:
A carrot would be an example of a taproot .
stomata regulate the exchange of gases in the leaves and help maintain homeostasis.
The leaves are often broad and flat because they are the main site of photosynthesis in a plant.
The force that allows water molecules to stick to other water molecules is called hydrogen bond .
The process by which plants release water into the air as vapor, while pulling more water upward into the leaves is called transpiration.
The role of cohesion and adhesion in plant transpiration ?Cohesion and adhesion draw water up the xylem. Transpiration draws water from the leaf. Negative water potential draws water into the root hairs. Cohesion and adhesion draw water up the phloem.
Several adaptations that leaves have undergone?They are adapted for photosynthesis by having a large surface area, and contain openings, called stomata to allow carbon dioxide into the leaf and oxygen out.
Why adaptations of plants in different habitats occur?Plants adapt or adjust to their surroundings. This helps them to live and grow.
What are the 3 most common nutrient deficiencies in plants?
The nutrients most commonly deficient in plants are phosphorus, nitrogen, and iron.
Nutrient deficiency symptoms occur as yellowing of leaves, interveinal yellowing of leaves, shortened internodes, or abnormal coloration such as red, purple, or bronze leaves.

The profusion of skin colors and physical characteristics of different humans is due to __________.
a. the development of pure races
b. the differences in climate and other living conditions humans encountered as they populated the globe
c. biology rather than evolution
d. the emergence of dominant groups in the last three centuries
Answer:
D
Explanation:
The family trees and the punett square shows you.
The profusion of skin colors and physical characteristics of different humans is due to the emergence of dominant groups in the last three centuries.
What is profusion of skin colors?The pressure needed to restore microcirculatory blood flow after the removal of a properly planned occlusion is known as skin perfusion pressure (SPP). A non-invasive test is the measurement of Skin Perfusion Pressure (SPP) with laser Doppler.
SPP measures have shown helpful in determining the best levels for amputation as well as in the assessment of peripheral vascular disease (PAD) for both critical limb ischaemia (CLI) and PAD.
Additionally, there is evidence in the literature that SPP measures can be helpful predictors of the potential for wound healing and, more recently, for the exploration of ischaemia over the ischial tuberosity in spinal cord injury patients.
Therefore, The profusion of skin colors and physical characteristics of different humans is due to the emergence of dominant groups in the last three centuries.

Describe what happened to the average yearly temperature on earth from 1970 to 1990. Give one possible reason why this change occurred.
Explanation:
In the given question, the graph has been shown representing the change in temperature on Earth between 1900 to 1990. The graph has been made by plotting temperature ( °F) on y-axis vs Year on the x-axis.
From the graph, it can be observed that the temperature on Earth has increased over the years but between 1970 to 1990 the temperature has increased from 56.9 °F to 58.1 °F approximately.
The reason for this increase in temperature could be accounted to the fact that the burning of fossil fuels like petrol, gas, coal and others increased over these years which increased the amount of carbon dioxide and other harmful gases in the atmosphere.
Due to the increase in these gas, the greenhouse effect was observed and the temperature of the Earth begins to rise at an alarming rate.
How can photosynthesis be related to cellular respiration?
-What's produced (made) by one is needed (the reactants) for the other.
-They both produce the same products.
-They both have the same reactants (need the same things).
-These two processes have nothing in common.
Answer:
These two processes are related because what's produced by one is needed for the other.
Explanation:
In photosynthesis, O2 and glucose are produced. Autotrophs (and heterotrophs too) use cellular respiration to make carbon dioxide and water from organic compounds - glucose - and oxygen; therefore, we can say that the glucose and oxygen are acting as reactants in the process of cellular respiration.
Photosynthesis can be related to cellular respiration because What's produced (made) by one is needed (the reactants) for the other.
What is photosynthesis and cellular respiration?Photosynthesis is a process by which plants produce oxygen and energy in the form of carbohydrates by combining sunlight, water, and carbon dioxide.Cellular respiration is a series of metabolic reactions and activities that occur within organisms' cells to transform chemical energy from oxygen molecules or nutrients into adenosine triphosphate (ATP) and then release waste products (CO2).How are Photosynthesis and cellular respiration interrelated?A significant link exists between photosynthesis and cellular respiration. The reactants of one process are the products of another. It's worth noting that the equation for cellular respiration is the total opposite of the equation for photosynthesis:Photosynthesis: 6CO2 + 6H2O → C6H12O6+ 6O2
Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O
Photosynthesis produces the glucose required for cellular respiration and the production of ATP. After that, the glucose is converted to carbon dioxide, which is subsequently used in photosynthesis. During photosynthesis, water is broken down to generate oxygen, but during cellular respiration, oxygen is mixed with hydrogen to form water. Cellular respiration requires oxygen produced by photosynthesis and releases carbon dioxide, whereas photosynthesis requires carbon dioxide and releases oxygen.
