Heterotrophic mode of nutrition
This type of nutrition can be categorized into parasitic mode, saprophytic mode and symbiotic mode of nutrition.
Parasitic mode:
In parasitic mode of nutrition, plants depend on other live plants or animals for their nourishment. Such plants are called as parasites and the ones on which parasites depend are called as hosts.
The insectivorous mode of nutrition is observed in plants like pitcher plant and the Venus fly trap. They purely depend on other insects and small animals for their nutrition.
Cuscuta is a parasitic plant which develops special roots called haustoria. Haustoria penetrate deep into host plant tissues and just absorb the nutrients from them.
Saprophytic mode:
The plants which exhibit saprotrophic mode of nutrition are called as saprotrophs. Saprotrophs are the plants that obtain their nutrition from dead and decaying organic matter. Saprotrophs secrete digestive juices onto dead and decaying matter to dissolve it and then absorb nutrients from it.
Examples of parasitic mode of nutrition are:
1.Tapeworms are segmented flatworms that attach themselves to the insides of the intestines of animals such as cows, pigs, and humans. They get food by eating the host's partly digested food, depriving the host of nutrients.
2.Fleas harm their hosts, such as dogs, by biting their skin, sucking their blood, and causing them to itch.
3. Barnacles, which live on the bodies of whales, do not seriously harm their hosts, but they do itchi g bcoz of barnacles.
Some examples of plants having saprophytic nutrition are as follows:
Corallorhiza trifida
Dipodium punctatum
Galeola septentrionalis
Monotropa uniflora
Neottia nidus-avis
So, like I wrote above, the mode of nutrition in which an organism obtains nutrients from dead and decaying organic matter is called saprophytic nutrition. Example - Rhizopus (bread mould), Mucor (pin mould), Yeast, Agaricus (mushroom) .

Which equation best represents the aerobic respiration reaction?
The chemical equation which best represent an aerobic respiration reaction is: D. Glucose + Oxygen -----> Carbon Dioxide + Water + ATP.
An aerobic reaction can be defined as both biological and chemical processes that generally takes place in the presence of oxygen.
This ultimately implies that, an aerobic reaction requires oxygen before it can occur.
On a related note, an aerobic respiration reaction refers to how the body of a living organism uses oxygen such as;
Running. Swimming. Walking. Jogging.Basically, the two main reactants (inputs) reactants for an aerobic respiration reaction include:
Glucose.Oxygen.Conversely, the end products of an aerobic respiration reaction are:
Carbon dioxide.Water.ATP.In conclusion, the chemical equation which best represent an aerobic respiration reaction is:
[tex]Glucose + Oxygen ---> Carbon \;Dioxide + Water + ATP[/tex]

The equation that best represents the aerobic respiration reaction is: Glucose+ oxygen→ Carbon Dioxide+ Water+ ATP.
In this equation, glucose (C6H12O6) is oxidized in the presence of oxygen (O2) to produce carbon dioxide (CO2), water (H2O), and energy. This is the process of aerobic respiration, which occurs in the mitochondria of cells to generate energy for cellular activities.
Vigorous breath is the organic cycle where food glucose is changed over into energy within the sight of oxygen. The majority of mammals, birds, humans, and plants use this kind of respiration.

seeds that are planted upside down are still able to grow into mature plants which explanation best explains this phenomenon?
Answer:
This question is incomplete but the completed question is below
eeds that are planted upside down are still able to grow into mature plants. Which explanation best explains this phenomenon?
(a)The roots change into branches, and the branches turn into roots.
(b)The roots grow toward the force of gravity, and the shoots grow away.
(c)The plant will become a smaller version of a mature plant.
(d)Roots always grow toward the dark, and shoots grow toward the light.
Two options appear to be correct here: options B and D
Explanation:
Regardless of the direction the seed is planted, the seed has the ability to re-position itself via the help of growth hormones that respond to gravity and redirect the seed into the proper orientation. However, after re-orientation of the seed, the root grows toward the direction of gravity (a process known as gravitropism) while the shoot grows toward the direction of sunlight (a process known as phototropism). Even though two options appear to be correct here, the most correct option based on he question is b
. Describea typical stress-strain curve and the relationship between the segments of the curve and stress and strain.
Answer:
the relationship between stress and strain that a particular material displays . it's unique for each material . it's is found by recording amount of strss at different values of strain. it is the stress point at which a specific material breaks under a given stress in a typical stress-strain curve , the breaking strength is less than the ultimate strength
Explanation:
The typical stress-strain curve and the relationship between the segments of the curve and stress and strain explain the relationship between these two as the Stress is the result of the force applied, and strain is the deformation of a material in response to stress.
What is the significance of the stress-strain curve?A typical stress-strain curve has several segments, including the elastic region, which represents the stiffness of the material, and the plastic region, which represents the point at which the material begins to permanently deform. Necking: a reduction in cross-section; ultimate strength, then a material's ability to deform until it reaches its ultimate strength, and so on.
Hence, the typical stress-strain curve and the relationship between the segments of the curve and stress and strain explain the relationship between these two as the Stress is the result of the force applied, and strain is the deformation of a material in response to stress.

Thank you!!!!!
Answer:
a) true
b) false
c) true
d) false
e) false
Explanation:
hi im taking ap biology and it's not my best subject but here r my reasonings:
a) inhibitors decrease the rate of reactions in general, so i would assume that increasing the number of inhibitors would decrease the overall rate or reaction
b) it's false bc allosteric inhibitors bind to a place on the enzyme other than the active site. u can see on the figures that the blue-green allosteric inhibitor is in a place other than the active site at the top
c) because allosteric inhibitors bind to a different place on the enzyme, this often results in an formational change in the enzyme. bc of this change in shape of the enzyme, this can rly prevent the substrate from binding to the active site
d) i dont think adding a competitive inhibitor will increase the number of products bc competitive inhibitors decrease the reaction rate by blocking substrates from binding to the active site :/
e) false bc competitive inhibitors do not bind to the substrates; they bind to the active sites, thus blocking the substrate from entering the active site. u can see this in the blue-green square at the top figures

Which factor increases as a result of increasing altitude? air pressure, air density, height of sea level or space between gas molecules
Answer:
space between gas molecules
Explanation:
as the altitude increases the air density decrease because of weaker gravity and these led to more distant of air molecule and the space between gas is increased
As the altitude increases the air density decrease because of weaker gravity and these led to more distance between air molecule and the space between gas is increased.
The answer is option D.
What is the effect of the increase in height?As the height increases, the pressure increases. - As the height increases, the air density increases. - Air pressure and congestion are very low at sea level. - Heavy air is more pressurized than small dense air.
Why does the pressure rise at higher altitudes?The gravitational pull between the earth and the air atoms is much larger than those distant molecules - they are heavier - pull them closer and increase the force (energy per unit) between them.

You examine an epithelial cell (skin cell) and notice the chromosomes are visible however it appears there are two nuclei in the cell. What is the best explanation for this observation?
a) the cell has just gone through the S –phase of the cell cycle so there is double the amount of DNA
b) the cell has just gone through telophase but not cytokinesis
c) the cell has gone through meiosis I and is preparing for meiosis II
d) the cell is in G1 and is preparing for DNA synthesis
Answer:
The best explanation if we observe an epithelial cell with chromosomes are visible and two cell nuclei is that the cell has just gone through telophase but not cytokinesis (option b).
Explanation:
A somatic cell, when found in mitosis, exhibits the chromosomes distributed in both poles and the outline of two nuclei in the telophase phase, just before cytokinesis.
In mitotic telophase:
Chromatids, which are chromosomes, are found in the cell poles. It initiates the formation of the nucleus membrane. The chromosomes begin to turn into chromatin. Disappearance of the mitotic spindle, duplication of organelles and cytoplasmic invagination.The division and differentiation of the nuclei in telophase is called karyokinesis. Later, cytokinesis occurs, where the daughter cells are separated.
The other options are not correct because:
a and d. In the other phases described, S and G1, no chromosome distribution is observed at the poles.
c. A somatic cell does not experience meiosis.
