one reason Mendel chose pea plants for his experiment.
Answer:
Peas were an ideal choice for Mendel to use because they had easily observable traits there were 7 of which he could manipulate
The main reason why Mendel used a pea plant rather than anything else was because a pea plant had observable traits that could be easily recognized. Seven, in particular, he could manipulate in his experiment. Finally, he would cross-pollinate the peas and study each trait that passed on from one pea to another.

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.
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.
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.

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).

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

Answer:
Mainly the root nodules serve as a home for nitrogen fixation
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.

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.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.

Explain the basic steps in the first half of photosynthesis. Describe the movement of electrons and the importance of hydrogen ions in developing a proton gradient that allows for ATP production.
Answer:
This simply refers to photolysis of water.
Explanation
Generally,two steps are involved in photosynthesis.
The light dependent stage or light reaction,(which is the first part of photosynthesis,
The light independent stage (which is the second part.)
The light independent reactions involved the trapping of sunlight by the photo systems, in the leaves,and the splitting of the water molecules by sunlight.
H20 + Sunlight → 1/2H+ +2 e- +1/2 O2.
The movement of electron can be cyclic or non cyclic photophosphorylation, In Cyclic, photo system 1 absorbs the electrons and pass these to the primary pigments in the leaves. This excited the electron in chlorophyll molecule to higher energy levels , The electron emitted from the leaves is by a process called by photoactivation The emitted electron do not return to the photosystems,rather they are pick up by the primary electron acceptors and returned to the chlorophyll molecules by electron carriers,NADP.
During this process Energy is released for ATPase synthase of ATP for phosphorylation of ADP with phosphate,
In Non-cyclic photophorylation,photosystem I and II absorbs the electrons as Z-scheme movement of electrons.,Photoactivation of chlorophyll takes place as in the Cyclic.The primary electron acceptors takes the excited electrons to move along the chain of electron carriers.This makes the photosystems positively charged.
Hence to regain stability the primary pigment of photo system 1 takes electrons from photosystem II.To replace its lost electrons, P II takes electrons from the photolysis of water.ATP is generated as the carriers molecules transport electrons from the energy produced.
The hydrogen ions is used for the production of electrochemical gradients,which supplies the energy used by the ATPase synthase for the ATPs production.The process is called chemiosmosis. It involved the transports of H atoms by NADPH into the stroma,and the splitting of these into protons and electrons,The electrons form ETC,which forms the PMF.The latter pumped protons into the thylakoid membrane,and as this returns it generate the electrochemical gradient.
The ATP is used in the Calvin Cycle for CHO,proteins productions,
