Some parts of the worlds rainforests haven’t been studied closely, and may contain species of plants which have benefits for humans. ‘Suggest and explain uses of stem cells taken from the meristem of a new species of plant.’
Answers
To determine the similarity of stem cells of one species of plant with that of another: By determining the similarity between the stem cells taken from two different species, it can be identified whether there is a possibility of clowning, of giving birth to new and improved species of plants that are beneficial for mankind, or that of interchanging the stem cells to boost up or slow down the growth of the plants. To determine whether the stem cells can be altered and reintroduced to make the plants grow in a specified manner: By altering and modifying the stem cells and reintroducing them back again, it is possible to restrict the growth of the plant to a specific size or shape. This trait of the stem cells can be used to make the plantation possible in compact areas as well as to grow the plants in the desired shapes.
To determine whether the speed of division of cells at the roots and appendages of the plant can be modified: By restricting or boosting the speed of the division of meristem cells using modified stem cells, the plant can be made to grow faster in a specific season and slower in another. This feature can be used to lower the vulnerability of the plant species towards various natural weathering actions.
Stem cells extracted from the meristem can be precisely examined for their effectiveness against illnesses that harm portions of the plants such as the roots, shoots, and appendages to ascertain the resistance against various plant diseases.
What is meristem?They can thus also be utilized to rebuild the damaged plant tissues if the newly discovered species becomes extinct.
It can be determined whether there is a chance of clowning, or of giving birth to new and improved species of plants that are beneficial to mankind.

Which are examples of active transport across the cell membrane? a. osmosis and diffusion b. diffusion and facilitated diffusion c. osmosis and chemiosmosis d. endocytosis and exocytosis
Answers
Answer:
d. endocytosis and exocytosis
Explanation:
These processes bring specific items in/out of the cell through active transport since the particles being brought in are generally large. Water for example, a much smaller particle, would use passive transport through the process of osmosis. Hope this helps!
Endocytosis and exocytosis are examples of active transport across the cell membrane.
Active transport is the movement of substances in and out of the cell through the membrane using energy and occurs against a concentration gradient.
Endocytosis is called the process by which cells incorporate into them molecules, large or small, that cannot pass through the cell membrane.An example is the endocytosis of the complex that is formed between receptor proteins of polypeptide or protein hormones at the level of the plasma membrane.
Exocytosis is the process by which different types of molecules contained in a cytoplasmic vesicle of a cell are secreted outwards.Insulin secretion is done in small pinocytosic vesicles that have insulin in colloidal dispersion, this secretion is in favor of a gradient, since insulin is more concentrated within the cell than in the extracellular space.
Therefore, we can conclude that endocytosis and exocytosis are examples of active transport across the cell membrane.

what causes water to enter plant roots from the soil?
a. water concentration in root hairs and the soil are equal.
b.water concentration in root hairs and the xylem are equal.
c.water concentration in root hairs is higher than in the soil
d.water concentration in root hairs is lower than in the soil
Answers
Answer:
D
Explanation:
The cell sap is hypertonic to the soil therefore an osmotic gradient is formed and the roots therefore intake water
What causes water to enter plant roots from the soil is mainly because the concentration of water in the root hairs is lower than in the soil. The correct option would be D.
Water moves from the soil into the root by osmosis.Osmosis is the movement of water molecules from the region of high water potential or concentration to the region of low water potential or concentration.Hence, water will enters the plant roots from the soil because the water potential in the soil is more than that of the root airs.

You want to estimate the number of canvas backs (a type of duck) at the Sacramento Wildlife Refuge. In two days you capture 200 canvas backs, mark all of them and release them. One month later you capture another 200 canvas backs, of which 100 were marked by you last month. Calculate an estimate for the population size of canvas backs.
A. 400
B. 100
C. 200
D. 300
E. 600
Answers
Answer:
Option A 400 individuals
Explanation:
Using this formula, we can estimate the population size of the canvas backs as this is a capture-recapture method.
N = (MxC) / R
Where N = estimated Number of individuals in the population
M = number of individuals captured and Marked = 200
C = total number Captured the second time (with and without a mark) = 200 and
R= number of individuals Recaptured (those with a mark) = 100
Thus, we have
N = (MxC) / R
= (200 x 200) / 100
= (40,000) / 100
= 400 individuals.

In his experiments with different competing pairs of Paramecium species, Gause found that sometimes both species persisted and sometimes only one species did. Which hypothesis did Gause propose in order to explain the cases in which both species persisted?
Answers
Answer: The options are not given, here are the options.
A. One species is much better competitor than the other.
B. Periodic disturbances allow for coexistence.
C. Two species tended to use different resources.
D. The two species experienced interference competition and not exploitative competition.
The correct option C.
Two species tended to use different resources.
Explanation:
From Gause experiments on competing paramecium pairs, He found out that most times both species persisted and sometimes only one did because the two species uses different resources.
Organisms normally compete for limited resources in order to survive and one intend to compete well while other suffer. Both in the case of competing paramecium pairs, the pair use different resources which make the to persist and survive well. Once the resource of one finishes, the other one will persist because it is still surviving on its available resources.

Explain the plasma membrane in easy way.
Answers
Answer:
The cell membrane (also known as the plasma membrane (PM) or cytoplasmic membrane, and historically referred to as the plasmalemma) is a biological membrane that separates the interior of all cells from the outside environment (the extracellular space) which protects the cell from its environment.[1][2] The cell membrane consists of a lipid bilayer, including cholesterols (a lipid component) that sit between phospholipids to maintain their fluidity at various temperatures. The membrane also contains membrane proteins, including integral proteins that go across the membrane serving as membrane transporters, and peripheral proteins that loosely attach to the outer (peripheral) side of the cell membrane, acting as enzymes shaping the cell.[3] The cell membrane controls the movement of substances in and out of cells and organelles. In this way, it is selectively permeable to ions and organic molecules.[4] In addition, cell membranes are involved in a variety of cellular processes such as cell adhesion, ion conductivity and cell signalling and serve as the attachment surface for several extracellular structures, including the cell wall, the carbohydrate layer called the glycocalyx, and the intracellular network of protein fibers called the cytoskeleton. In the field of synthetic biology, cell membranes can be artificially reassembled.[
