What is the relation between leaf venation and the type
of roots?
Answer:
When the veins in leaves are irregularly distributed to form a channel, it is known as reticulate Venation. Plants with reticulate venation in their leaves are likely to have tap roots. Plants like carrot or rose have leaves with reticulate venation and tap roots.
Explanation:
hope it helps :D
Answer:
Explanation:
those plants that have parallel venation leaves have fibrous root system and the plant that have reticulate venation of leaves have tap root system.

Which best describes a bacteriophage
Bacteriophages are a special class of viruses that infect and spread only within bacteria.
Bacterium refers to bacteria, while "phage" means to eat or devour. Together, these two words form the term "bacteriophage". Highly specialized viruses called bacteriophages attach to the surface of bacterial cells and introduce their genetic material into the host bacterium.
Once the bacteriophage's genetic material enters the bacterial machinery, it causes it to make multiple copies of the phage particles. The host bacterium is eventually killed, and freshly produced phages are freed to infect additional bacterial cells. Nature is full of bacteriophages, which are important for managing bacterial populations and building microbial communities.

Although sound can be heard, it is not
considered to be matter. Which of the
following best explains this?
A. Sound cannot be captured for analysis by scientists.
B. Sound exhibits qualities of both energy and matter.
C. Sound cannot be measured.
D. Sound does not have mass nor does it take up space.
Answer:
D
Explanation:
all the others dont make sense
In contrast to other sounds, the sound is the movement of a pressure wave across a medium of particles. Being a wave, it is not regarded as a kind of substance, hence option D is correct.
What are the characteristics of sound?Because the molecules of a solid are closer together and can transfer vibrations more quickly, sound passes through solids more swiftly than through liquids and gases.
Since gas molecules are the farthest apart, sound moves through them at the slowest speed, it instructs the mind to decipher the incoming sound.
The energy comes from an outside source, such as singing or drumming. It may also be viewed as the vibrations moving through the material world.
Therefore, the physical vibration waves that pass through the air to reach the ears are referred to as sound energy, hence option D is correct.

What are sustainable use practices?
any materials that exist in nature and that are used by humans
the managed consumption of natural resources to prevent their depletion or environmental destruction
the deployment of fossil fuels to environments that previously did not have access to such resources
ways in which individuals are able to conserve native animal and plant species
Answer:
B.
Explanation:
Sustainable practices are all about the managed consumption of natural resources to prevent their depletion or environmental destruction.
What is sustainability?It refers to the management of resources in such a way that their depletion is prevented and the environment is conserved in the process.
Sustainable practices include actions targeted at conserving resources to prevent abusive or wanton use and ensure that the future heritage is intact.
For example, cutting down trees for construction and following it up with the planting of other trees is a sustainable practice. By doing so, trees will not get depleted in the forest.
The correct option is, therefore, the first option.

Which of the following would be the best definition of diffusion? The movement of molecules....
- from an area of higher concentration to an area of lower concentration
-using energy
-down the concentration gradient
-from an area of lower concentration to an area of higher concentration
-using energy
-up a concentration gradient
-from an area of low concentration to an area of high concentration
- without energy
- up the concentration gradient
-from an area of higher concentration to an area of lower concentration
-without energy
-down the concentration gradient
Answer:
-from an area of higher concentration to an area of lower concentration
-without energy
-down the concentration gradient
Explanation:
Simple diffusion does not require energy. This is likely what the question is referring to.
An example of simple diffusion:
If you blow up a balloon and then poke a small hole in it. The air will leak out from the high concentration inside the balloon to the low concentration outside of the balloon. It does not require any energy to be put it--it leaks out on its own as long as there is a hole.
Answer:
-from an area of low concentration to an area of high concentration
- without energy
- down the concentration gradient
Explanation:
The movement of molecules from an area of low concentration to an area of high concentration, without energy, down the concentration gradient is correct.

Suppose the total area of a habitat is 200m2 and 1m2 quadrant is placed in randomly selected areas . If the average number of plans species in 20 randomly selected area of the habitat is 2 , what will be the number of plant species of the habitat .
Answer:
400 plant species
Explanation:
The average number of species in 20 randomly selected area = 2
Size of quadrat = 1 m2
Total size of habitat = 200 m2
Population density per 1 m2 = 2
if 2 plant species occupy 1 m2 of the habitat area, then the number of plants that will occupy 200 m2 equals:
2 x 200 = 400 plant species

plz help!!! Gall flies lay their eggs in developing shoots of the tall goldenrod. When the fly larvae hatch, they release chemicals that cause the plant tissue to swell around the larvae, causing a resultant gall to form. The gall flies are prey for the parasitic wasp that lays its eggs in the smallest galls. After the wasp larvae hatch, they eat the fly larvae. The gall fly is also prey for the downy woodpeckers that feed on the larvae of the largest galls. Which type of natural selection may the gall fly be subject to?
Directional selection
Disruptive selection
Normal distribution
Stabilizing selection
