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.advantages of cutting crops with sickle?
Answer:
The advantages of cutting crops with a sickle is that it's very environmental friendly. Sickle doesn't produce harmful chemicals like nitrate and biogas that can cause pollution to the environment or to the crops. However, sickle cutting is a very tremendous work.
Explanation:
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.

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.

Which of the following is TRUE regarding the flow of blood through the heart:__________
a) The pulmonary artery carries deoxygenated blood.
b) The aorta is responsible for carrying oxygenated blood to the pulmonary system.
c) During systole, blood is going from the atria to the ventricles by gravity.
d) During diastole, blood is flowing over the semilunar valves
Answer:
a The pulmonary artery carries deoxygenated blood.
Explanation:
This is the the only artery that transports deoxygented blood in mammals. specifically it carry deoxgenated blood from the the atria to the pulmonary circulation. That is to the lungs for the exchange of the C02 in the deoxygenated blood with oxygen in the lungs.
The blood thus become oxygenated,and therefore return through the pulmonary veins to the left ventricle.
From the left ventricle ,through ventricular systole,blood is empty into the aorta through the aortic valves into the systemic circulation.
Although,they carry blood away from the heart,but the blood is de oxygenated instead of the usual oxygenated by arteries,They are still regarded as arteries because of convey of blood away from the heart,a typical role of arteries
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.

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.

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.

Corn oil has a density of 0.7 g/cm3. Water has a density of 1.0 g/cm3. A piece of plastic with a density of 0.9 g/cm3 will _____.
sink in corn oil and in water
sink in corn oil and float to the top of water
float in corn oil and in water
sink in corn oil and float in the middle of water
Answer:
Corn oil has a density of 0.7 g/cm3. Water has a density of 1.0 g/cm3. A piece of plastic with a density of 0.9 g/cm3 will sink in corn oil and float to the top of the water.
Explanation:
Density is a unit that let us know the quantity of mass that a substance has per unit of volume. In a solution, the component with lower density will float, and be on the surface.
If we compare the densities of corn oil and a piece of plastic, the plastic will sink because its density ( 0.9 g/cm³ )is higher than the one of the corn oil (0.7 g/cm³).
In the case of the water, the plastic will float to the top because its density ( 0.9 g/cm³) is lower than the one of water (1.0 g/cm³).

Answer:
23.2
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.
Which of the following best describes passive transport?
A. Cellular transport that requires cellular energy in the form of ATP.
B. Cellular transport that does not require cellular energy.
C. Cellular transport in which the cell membrane pinches around a substance in order to bring it into the cell.
D. Cellular transport in which substances move from areas of low concentration to areas of higher concentration.
Answer:
d
Explanation:
passive transport needs no energy W when transporting from high to low and need energy when transporting from low to high
Cellular transport that does not require cellular energy is the example of passive transport. The correct option is B.
What is passive transport?Passive transport is a type of membrane transport in which substances are moved across cell membranes without the use of energy.
Differing from active transport, the one that uses cellular energy to move substances across cell membranes, passive transport utilizes the second law of thermodynamics to move substances across cell membranes.
Passive transport processes play critical roles in homeostasis. They maintain normal conditions within the cell and the organism as a whole by allowing substances to move into and out of the cell.
Active transport is defined as the movement of a solute from one side of the cell membrane with a low electrochemical potential to the opposite side with a higher electrochemical potential.
Thus, the correct option is B.
