Answer: This shows that over time, some insects can become "pesticide-resistant" meaning that pesticides don't affect them anymore. And this only happens every few generations. Therefore, each generation is being naturally selected and accumulating variations that make them resist the chemicals. This shows that each cockroach's genes are changing to give them variation from the rest of the population.

Additional vascular tissue produced as secondary growth in a root originates from which cells?.
Answer:
The vascular cambium produces new vascular tissue and is responsible for most of the radial expansion of stems and roots.
Explanation:
Does this answer your question???
Additional vascular tissue produced as secondary growth in a root originates from Vascular cambium cells.
What is secondary growth?
Secondary growth happens in the vascular cambium of those plants, that is a skinny layer of tissue containing actively dividing cells. The vascular cambium is a meristematic tissue that develops among the stem's number one xylem and number one phloem.
The Vascular Cambium and Secondary Growth. The vascular cambium and cork cambium are secondary meristems which can be fashioned in stems and roots after the tissues of the number one plant frame have differentiated. The vascular cambium is accountable for growing the diameter of stems and roots and for forming woody tissue.

Answer:
True!
Explanation:
These are composed of intersecting horizontal and vertical lines that form a cartesian plane.
, The number plane, or Cartesian plane, is divided into four quadrants by two perpendicular lines called the x-axis, a horizontal line, and the y-axis, a vertical line. These axes intersect at a point called the origin. Once a unit distance has been chosen, the position of any point in the plane can be uniquely represented by an ordered pair of numbers (x,y). For the point (5,3), for example, 5 is the x-coordinate and 3 is the y-coordinate, sometimes called the first and second coordinates. When developing trigonometry, the four quadrants are usually called the first, second, third and fourth quadrants as shown in the following diagram.

Nervous tissue is composed of _ and two types of cells: _ and _
Answer:
Nervous tissue is composed of nerves and two types of cells: neurons and glial cells.
Explanation:
Nerves tissues are composed of nerves and two types of cells are neurons and glial cells.
What do you mean by Nervous tissues?Nervous tissues may be defined as tissues that are found in the brain, spinal cord, and nerves. They are responsible for coordinating and controlling many body activities.
Neurons are the primary type of cells that are associated with the nervous system, while glial cells may be defined as the neurons of the central nervous system which play an important role in the conduction of nerve impulses, but they are non-excitable cells.
Therefore, nerve tissues are composed of nerves and two types of cells are neurons and glial cells.

With the help of an activity show that carbon dioxide is neccessary for Photosynthesis.
Explanation:
To prove the necessity of carbon dioxide in photosynthesis following steps need to do
Insert a part of the leaf of a destarched plant into a conical flask containing potassium hydroxide.
Potassium hydroxide solution absorbs the carbon dioxide gas from the air present in the glass bottle.
Leave the plant sunlight.
After few hours, perform a starch test to this and another leaf of the same plant.
Observation-
Leaf exposed to the atmosphere are bluish black.
Leaf exposed to KOH does not change to blue-black colour
Result- Starch is present in the green part of the leaf.
Conclusion- Presence of starch proves that chlorophyll is necessary for photosynthesis as it traps sunlight.
