A small number of birds arrive on an island from a neighboring larger island. This small population begins to adapt to the new food plants available on the island, and their beaks begin to change. About twice a year, one or two more birds from the neighboring island arrive. What effect do these new arrivals have
Answer:
The environmental variation
Explanation:
Environmental variation has a big role for their beaks to change in a size and shape , that means if the birds like the condition of the place specially birds like to eat cactus fruits that is the reason for their beak rapid change
Which three are formed due to compression?
a) syncline, normal fault, and strike-slip fault
b) anticline, syncline, and reverse fault
c) normal fault, anticline, and strike-slip fault
d) reverse fault, strike-slip fault, and syncline
Answer:
b) anticline, syncline, and reverse fault
Explanation:
Compression helps in squeezing rocks together and leads to folding and fracture in rocks.
Anticline, syncline, and reverse fault are geological structures formed due to compression.
A syncline is a geologic fold in which the younger layers appears closer to the center of the structure, Anticline have so many small compression that developed above thrust faults, and reverse fault is a geological structure in which one side appears taller than the other.
Hence, the correct answer is b.

Explain the concept of growth using these terms: differentiate, meristem, elongation, and vascular cambium.
Answer: Well for one, Differentiate is when a cell matures and is used in a specific function. Meristem is a cell which never differeates and constantly divides so it is a mitotic cell. Elongation is the plant growing length wise therefore the meristem elongates the plant. Vascular cambium is the cambium which starts out in vascular bundles of the plant and then grows to form a ring inside the stem of plants that live for more than year- it causes and increase in thickness of the stem and branches.

Describe the difference between a chemical and an electrical gradient. What's an electrochemical gradient? Do you think an electrochemical gradient can have conflicting component gradients?
Answer:
1) The difference between chemical gradient and electrical gradient is that chemical gradient refers to the change in concentration of an ion or molecule in a solution across a biological membrane while electrical gradient refers to the existence of an electrical potential difference that leads to the movement of charged ions towards or away from the electrical potential
2) Electrochemical gradient is the charge and ion concentration difference across a biological membrane
3) No because electrochemical gradient which consists of both an electrical and chemical gradient have a complementary effect in determining the level of the electrochemical gradient.
Explanation:
The electrochemical gradient is the gradient of the electrochemical potential and is usual for a positive and negative ion that can move across the membrane.
What is the electric gradient ?The gradient is made of two parts that are chemical which is different in solutes that can move across the membrane and have an electrical component that shows difference in changes across the membrane.
The electrostatic gradient is a potential used in an iron that can be used across the membrane. Due to unequal concertation of ions, they will move across the simple diffusion.
The electrochemical has potential in electroanalytical industries as batteries and fuels. The gradient has contrasting components as change across the membrane.

A person with the genetic disorder Klinefelter's syndrome has an extra x-chromosome (genotype XXY). What can you predict is the most likely genetic mutation that results in Klinefelter's syndrome?
Answer:
The correct answer is non-disjunction at the time of meiosis.
Explanation:
A disorder, which takes place in males exhibiting an additional X-chromosome and is an outcome of an error in cell differentiation resulting in anomaly known as the Klinefelter's syndrome. Due to non-disjunction the egg or the sperm may acquire an additional X-chromosome. When these unusual cells take part in the genetic makeup of a person, then that individual most probably suffers from the condition termed as Klinefelter's syndrome.
In the majority of the circumstances, the division of the cells takes place generally during the development of the sperm, and at the same time, there may be certain errors at the time of egg development. Generally, the condition is mostly seen in the offspring of women that conceive after the age of 35.
a) Name the structures that: i) Carry water and mineral salts to the leaf ii) Prevents too much water loss from the upper surface of the leaf iii) Opens to allow gases to pass into and out of the leaf iv) Is the site for most of the photosynthesis taking place v) Is the layer where light is able to pass through directly b) How does a leaf protect itself from unwanted intruders like bacteria from getting in and stopping important reactants from going out? PLEASE ANSWERR
Answer:
a) i) Xylem
ii) Upper epidermis
iii) Stoma
iv) Chroloplast
v) Palisade cell layer
b) By a waxy layer on the cuticle of the leaf
Explanation:
The plant's leaves have a large surface area that is capable of absorbing sunlight. The plant's waxy layer in the surface of the leaf protects it from the loss of water, as well as of diseases caused by the entry of microorganisms. The palisade cell's surface is a single layer of cells underneath the upper epidermis that is adapted to absorb light energy.
The waxy layer is a primary physical barrier composed of insoluble polymers and lipids whose function is to protect the leaves against the entry of harmful organisms including virus, bacteria and fungus. Moreover, the plant's waxy cuticle is also a barrier that prevents the loss of water and solutes.

In northern Canada, a population of rabbits was predominantly white in color. The allele for white color is recessive while the allele for gray color is dominant. Over the last several decades, the average annual temperature of this area has increased and the long-term deposits of ice and snow have become scarce. In this case, the frequency of a previously rare allele becomes more frequent in the population. This is an example of
Answer:
The options are
A) nonrandom selection.
B) disruptive selection.
C) directional selection.
D) stabilizing selection.
The answer is C)directional selection.
Explanation:
Directional selection is a type of natural selection and occurrence in population genetics. It involves a phenotype which is most extreme being chosen over forms of phenotypes. It occurs over a period of time when the allele frequency completely aligns in the pattern of the extreme phenotype.
This explains why the frequency of a previously rare allele becomes more frequent in the population after a certain period of time.

Explanation:
Why might the carrying capacity for humans in the United States change if Americans ate more plant products than animal products? Feeding higher on the food chain would make more energy available for humans to assimilate. Consuming plant products would provide less energy because they are generally less digestible than meat. Eating producers would make available about 10 times more energy than eating primary consumers. A diet made up of more plant and fewer animal products would decrease the amount of energy available in food sources.
Answer:
The correct option is:Food producers would make approximately 10 times more energy available than primary consumers.
Explanation:
Diets based on sugars, carbohydrates, fibers, proteins and vegetable fats (that is, with the increased consumption of fruits and vegetables) have much less complex structures than the protein in meat, so much more energy is obtained and easier and faster than vegetables.
A clear example is that carbohydrates have a digestion that lasts between half an hour and an hour, while meat takes at least an hour and a half to digest.
Meats are complex protein structures with primary, secondary and tertiary junctions that must be digested and corrupted with gastrointestinal enzymes, whereas the carbohydrate carbohydrates of fruits and vegetables already begin their digestion in the human mouth thanks to alpha amylase.
The faster the digestion, the faster the energy is assimilated in the form of glucose, and the energy currency that is ATP is greater in diets rich in carbohydrates like the one we are writing, based on fruits and vegetables.

Cytochalasin D is a drug that prevents actin polymerization. A cell treated with cytochalasin D will be inhibited from doing all of the following EXCEPT:________.
a) extend pseudopodia
b) move vesicles within a cell
c) contract muscle fibers
d) divide in two
Cytochalasin D is a drug that prevents actin polymerization. A cell treated with cytochalasin D will be inhibited from doing all of the following except move vesicles within a cell. Hence option b is correct.
What is actin polymerization?Actin polymerization is defined as a monomers associate with and disassociate from the ends of actin filaments in this reversible process. Actin filament polymerization typically takes place over three phases: a steady state phase, an elongation phase, and a nucleation phase. Actin filament assembly involves the phases of nucleation, elongation, and steady state.
A cell-permeable fungus toxin called cytochalasin D attaches to the barbed end of actin filaments and prevents both subunit interaction and separation. About 20 known mold-derived substances collectively known as cytochalasins impact actin stress fibers and cause fast actin depolymerization.
Thus, cytochalasin D is a drug that prevents actin polymerization. A cell treated with cytochalasin D will be inhibited from doing all of the following except move vesicles within a cell. Hence option b is correct.

A large asteroid impact occurs, kicking up dust that blocks the Sun and prevents plants from photosynthesizing. What would most likely happen as a result of the asteroid impact? More earthquakes would occur across the planet. Some plants would evolve to use dust as a source of food. Many plants would perform photosynthesis without sunlight. Many species would eventually die off because they lack a food source.
Answer:
Many species would eventually die off because they lack a food source.
Explanation:
Photosynthesis can be defined simply as the biological process of using light to synthesize food (in the form of glucose). It is a process that takes place in plants and involves the synthesis of sugar using inorganic products such as water and carbon dioxide.
[tex]6CO_2 + 6H_20 + (energy) → C_6H_1_2O_6 + 6O_2[/tex]
The process consists of two stages namely;
Light reactionLight independent reaction.The products from the light reaction are utilized in the light-independent reaction.
Hence, without light energy, the process of photosynthesis cannot proceed and plants will not be able to manufacture foods. Without foods, many plant species would die off.
Answer:
I'm pretty sure it's D and not C.
Explanation:
