When the embryo reaches about 500 cells, what best describes its growth and division? A. One daughter cell is a stem cell, one is a tissue cell, they stop being smaller than the parent cell B. Both daughter cells are stem cells at this point and are smaller than the parent cell C. Both daughter cells become specialized cells, they stop being smaller than the parent cell D. One daughter cell is a stem cell, one is a specialized tissue cell, both are smaller than the parent cell
Answer:
B. Both daughter cells are stem cells at this point and are smaller than the parent cell.
Explanation:
The embryo passes through several consecutive cell divisions. With each division, the daughter cells become smaller in relation to their mother cells. In addition, these cells are embryonic and can be called pluripotent. This is because they have the ability to transform into any type of cell that the human body needs, including tissue cells.
Q23 Which of the following describes the correct relationship between heart sounds and blood pressure? A.Systolic blood pressure is associated with the first heart sound. B. Systolic blood pressure is associated with the second heart sound. C. Diastolic blood pressure is associated with the first heart sound. D. Diastolic blood pressure is associated with the second heart sound.
Answer:
diolostic blood preasure is associated with the second heart sound
Explanation:
Korotkoff sounds are the sounds heard by the health professional who measures the blood pressure with a blood pressure monitor and a stethoscope placed on the patient's brachial artery.
Korotkoff described five types of noise:
* The first sound is a snap corresponding to the systolic pressure. The noise is clear, repetitive on at least two consecutive systoles.
* The second sound is a soft whisper, more or less prolonged, audible between the systolic pressure and the diastolic pressure.
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.

The majority of stomata are located on the underside of plant leaves reducing their exposure to heat and air current.
Explanation:
Answer:
a stomata is a pore in the coat of the leaves and/or stems
a stomata is found on stems and/or leaves
Darwin's Hypothesis of Evolution by Natural Selection included the observation that populations often grow faster than the food supply and therefore individuals need to compete for resources. Darwin borrowed this idea from the work of:
Answer:
Thomas Malthus on his essay on population.
Explanation:
Malthus concluded that human population grow faster than the available resources in their environment.However,no matter how this population increases,selection pressure like famine,natural disasters,always keep the population in check,thus maintaining the population size within moderate levels.
He believed the weakest in the population (with little resistance to the selection pressure) will die,thereby reducing the population, encouraging the survival of the fittest,and stabilizing and preventing expulsion.
Darwin, assumed that the surviving organisms in the population must have inherited certain characteristics/traits from their parents,which make them to resist the selection pressures.He called the surviving ones the survival of the fittest by natural selection.
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.

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.

The sudden rapid movement of an unsaturated cohesive mass of soil, regolith, or bedrock is a The sudden rapid movement of an unsaturated cohesive mass of soil, regolith, or bedrock is a:______
a) debris avalanche.
b) mudflow.
c) landslide.
d) rockfall.
Answer:
The correct option is C: landslide
Explanation:
A landslide is a huge amount of land, rocks, and other materials that moves downhill. These land moves are caused by erosion and other strengths that may cause the land to move and fall from a steep hillside. Erosion might cause separation of different material layers, and when a land o rocky layer is separated from its immediately anterior one, gravity causes the fall of these layers.
In general, these land moves are very destructive. They can cover rivers, routs, buildings, among others, putting in danger any kind of life.
There are other moves very similar to landslides, such as mudflow, avalanche, or rockfall.
Rockfall refers to the fall or big rocks from a precipice or steep hillside.
Mudflow refers to a thick stream of mud and other materials.
Avalanche refers to the collapse of snow and other materials.

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.

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.

In the late 1870s, Charles Darwin and his son Francis discovered that if the tip of the grass was covered, phototropism did not occur, even though the rest of the grass was exposed to light. However, if the rest of the plant was covered and only the tip exposed to light, the grass bent a few centimeters below the tip. How could light striking the tip of the grass cause bending a few centimeters from the tip
Answer:
The summary of the particular subject is provided in the segment below on clarification.
Explanation:
Noticed that saplings of the plant would still curve forward into light unless the tip of their ranges were available. The crop developed straight ahead as they cut the edge of such a grass crop, instead of just rotating forward towards the ground.The target stayed straightforward as they put an opaque caps over its end. However, when individuals positioned a transparent caps on its own edge, or perhaps an opaque mask over its core, it streamlined.This was found that perhaps the shoot's tip was essential to detect light. Acknowledged that although the answer to development, trying to bend the shooting, actually happens beneath the tip. A certain message was conveyed downwards from either the service charge to the take the shot's growing market.Any of a large group of diseases characterized by a condition in which the immune system produces antibodies against its own tissues, mistaking healthy cells, tissues, or organs for antigens is called a/an
