Answer:Photosynthesis in desert plants has evolved adaptations that conserve water. In harsh, dry heat, every drop of water must be used to survive. Because stomata must open to allow for the uptake of CO2, water escapes from the leaf during active photosynthesis. Desert plants have evolved processes to conserve water and deal with harsh conditions. A more efficient use of CO2 allows plants to adapt to living with less water.
Some plants such as cacti can prepare materials for photosynthesis during the night by a temporary carbon fixation and storage process, because opening the stomata at this time conserves water due to cooler temperatures. In addition, cacti have evolved the ability to carry out low levels of photosynthesis without opening stomata at all, a mechanism for surviving extremely dry periods.

Cactus: The harsh conditions of the desert have led plants like these cacti to evolve variations of the light-independent reactions of photosynthesis. These variations increase the efficiency of water usage, helping to conserve water and energy.
CAM Photosynthesis
Xerophytes, such as cacti and most succulents, also use
phosphoenolpyruvate (PEP) carboxylase to capture carbon dioxide in a process called crassulacean acid metabolism (CAM). In contrast to C4 metabolism, which physically separates the CO2 fixation to PEP from the Calvin cycle, CAM temporally separates these two processes.
CAM plants have a different leaf anatomy from C3 plants, and fix the CO2 at night, when their stomata are open. CAM plants store the CO2 mostly in the form of malic acid via carboxylation of phosphoenolpyruvate to oxaloacetate, which is then reduced to malate. Decarboxylation of malate during the day releases CO2 inside the leaves, thus allowing carbon fixation to 3-phosphoglycerate by RuBisCO. Sixteen thousand species of plants use CAM.

When a red 4 o'clock flower with a white flower, all of the offspring are pink. This type of inheritance is known as:_______ a. codominance b. incomplete dominance c. multiple alleles d. epistatsis
Answer:
b. incomplete dominance
Explanation:
Incomplete dominance is a type of inheritance that does not confirm to Mendel's principles of inheritance i.e it is non-mendelian. Incomplete dominance occurs when an allele of a gene does not completely mask the expression of another allele of the same gene, hence, the two alleles combine to form a heterozygous that is different but intermediate of both parent phenotypes.
This is the case in this question where the red allele (R) of a four o'clock plant is INCOMPLETELY DOMINANT over the white allele (W), hence, they both produce an intermediate pink phenotype (RW), which is a blending of both red and white phenotypes.
Are cells and DNA the same thing?
Answer:
We learned in biology class that every cell in the body has the same DNA. Whether a heart cell, skin cell or muscle cell—they all read from the same genetic blueprint. Now, scientists are learning there is more to the story.
Almost all of the cells in your body share the same DNA as was found in that first cell. Your DNA contains all of the information needed for making you. This information is stored in the over 20,000 human genes found in almost all your cells.
Your teacher has given you a plant to observe. You notice the leaves of the plant are dotted with openings. These openings are known as stomata. When open, stomata allow the plant to take in carbon dioxide, release oxygen. Moisture also evaporates through stomata helping to draw water from the roots up into the plant. How does the presence of stomata allow cell organelles to work together?

Dolphin fins and shark fins: _________
a. are probably built by different genes.
b. are an example of divergence.
c. suggest these two populations could interbreed.
d. are evidence that adaptive evolution is mainly driven by random forces.
e. None of the above is correct.
Answer:
a. are probably built by different genes.
Explanation:
Although sharks and dolphins are aquatic animals belonging to the vertebrate group, sharks are fish while dolphins are mammals. Sharks belong to the class Chondrichthyes which are fish that have a cartilaginous skeleton. On the other hand, dolphins are mammals (class Mammalia) which are animals mainly characterized by the presence of mammary glands. In consequence, both species are not closely phylogenetically linked, thereby those genes involved in the development of the integumentary system (skin) in both species are expected to be different.
Flowering plants are ___.
A.) gymnosperms
B.) laurasians
C.) angiosperms
D.) archaeopteryx
Answer:
C
Explanation:
The flowering plants, also known as Angiospermae, or Magnoliophyta, are the most diverse group of land plants, with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. Etymologically, angiosperm means a plant that produces seeds within an enclosure; in other words, a fruiting plant. The term comes from the Greek words angeion and sperma.
List the inputs and outputs of photosynthesis. what parts of the plant are responsible for taking in each of the inputs
Answer:
Inputs: 6CO2 and 6H2O with light energy
output: C6H12O6 and 6O2
Leaves, roots are the major parts of the plant responsible for taking in each of the inputs
Explanation:
The photosynthesis process is the process where carbon dioxide and water are converted into glucose and oxygen in the presence of light. The products of this process act as substrates during cellular respiration. The photosynthesis process can be represented as:
6CO2 + 6H2O ------> C6H12O6 + 6O2
inputs ↑ outputs ↑
Inputs of the reaction are:
1. Carbon dioxide - 6CO2
2. Water - 6H2O
3. light energy from sun
Outputs are:
1. Glucose - C6H1206
2. Oxygen - 6O2
b. The parts of the plant is responsible for taking inputs during photosynthesis is the leaf as it has chloroplast that trapped the light and also helps in getting carbon dioxdie and roots that helps in absorbing water.

When a person is cut, the injured tissue initially releases chemical signals into the bloodstream. These chemicals signal platelets to be attracted to the injured area. if this is a positive feedback mechanismwhich of the following must be part of the process? The heart would slow down to cause a drop in blood pressure. Platelets would release signals to stimulate the production of more platelets. Blood vessels around the cut would constrict to decrease the surface area exposed to the platelets. Chemical signals released would cause a decline in platelet production
Answer:
Platelets would release signals to stimulate the production of more platelets
Explanation:
Positive feedback mechanism is one of the two types of feedback mechanisms (other being negative feedback mechanism) in which the products of a process stimulates more of that product to be synthesized or produced. In other words, the result of a reaction increases the secretion of more results.
In this case where the injured tissue of a cut initially releases chemical signals into the bloodstream. These chemicals signal platelets to be attracted to the injured area. However, if this is a positive feedback mechanism as explained above, Platelets would release signals to stimulate the production of more platelets.

Tony spaces 5 plants apart equally along a line, with the first plant directly in front of a window and the last plant 30 feet away from the window. He gives them equal access to air and water and then monitors the amount of gas each plant releases.Which gas is Tony monitoring and what trend is hemostlikely to see in the data he collects?
A.He is monitoring oxygen. The amount of gas released should be highest for the plant in the middle and lowest for the plants at the ends.B.He is monitoring carbon dioxide. The amount of gas released should be highest for the plant in the middle and lowest for the plants at the ends.C.He is monitoring oxygen. The amount of gas released should be highest for the plant closest to the window and lowest for the plant farthest away from the window.D.He is monitoring carbon dioxide. The amount of gas released should be highest for the plant closest to the window and lowest for the plant farthest away from the window.
Answer:
The correct answer would be - C. He is monitoring oxygen. The amount of gas released should be highest for the plant closest to the window and lowest for the plant farthest away from the window.
Explanation:
The release of the oxygen gas in the process of photosynthesis depends on the rate of photosynthesis which depends on various factors such as carbon dioxide, light, and water. In this experiment air (carbon dioxide), water is constant only factors that are changed is light, and an increase in the light energy increase the rate of photosynthesis, and a decrease in the intensity of light depend decreases the rate of photosynthesis.
Thus any change in the light would affect the release of the oxygen gas which is measured through this experiment and gas released should be lowest for the plant farthest away from the windowand highest for the plant closest to the window.
