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

PLEASE HELP!!! A scientist concludes that genetic inheritance of a mutated (changed) gene, such as a gene change that creates different-colored organisms in a population, is more beneficial to an organism over time and contributes to biological fitness. Discuss why a scientist would make that claim.
i posted a few min. ago and someone stole 30 points by answering and saying they couldnt help. please answer the question if you can and dont steal my points....
Answer:
When the organism inherits a mutated gene creating new colored organisms into the population, this can increase diversity. As more organisms inherit the same mutation, the population will become more variated, which can increase the organisms abilities to survive and adapt in a changing environment, and also improve the biological fitness of individuals; resulting in allowing more organisms to reproduce successfully.

Explanation:
A student claims that electronegativity is not related to the
concept of polarity. Use water as an example to provide
reasoning to refute the student's claim.
PLEASE HELP!
Answer:
Please find the explanation below
Explanation:
Polarity of a molecule is the function of the difference between the electric charges of two atoms that make up the molecule. This polar nature is greatly influenced by the ELECTRONEGATIVITY, which is the ability to attract electrons, of the atoms involved. For example, using water molecule, H2O, as a case study.
Water is known to be a highly polar molecule due to the electronegativity values of the atoms that make up its molecule. Oxygen atom is a more electronegative atom than hydrogen, hence, it pulls more electrons towards itself, leaving the hydrogen atom more electropositive. This forms the difference in the electrostatic force between oxygen and hydrogen, making water POLAR.
HENCE, the student is wrong to have said electronegativity is not related to the concept of polarity.
Which of the following characteristics is shared by all modern living systems?
A. Multicellular body systems

D. Sub-cellular organelles
Answer:
B-Condon's based on a triplet code
Expl
The characteristic shared by all modern living systems among the options provided is DNA as the genetic material. Therefore option C is correct.
DNA (deoxyribonucleic acid) is a molecule that carries the genetic instructions for the development, functioning, and reproduction of all known living organisms. It is a long, double-stranded helix structure composed of nucleotides.
Thus, DNA as the genetic material is a fundamental characteristic shared by all known modern living systems.
It encodes the instructions necessary for the development and functioning of an organism, allowing for the transmission of genetic information from one generation to the next.

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.

How can someone become paralyzed after motor nerves work cut?
Dogs have 39 chromosomes. Each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere. Once the chromosome has split, each chromatid is called a daughter chromosome. At the end of cytokinesis, how many daughter chromosomes will be found in each dog cell?
Answer:
39 daughter chromosomes
Explanation:
This question is describing the MITOTIC process, which involves the synthesis of two daughter cells from one parent cell. In mitosis, sister chromatids, which forms a chromosome, separates at their centromere to become individual chromosomes in their respective daughter cells.
N.B: Mitosis produces two daughter cells which are identical in chromosome number.
In this case, a dog is said to have 39 chromosomes in its diploid cell. Since two chromatids make up one chromosome, 78 chromatids will be found in the dog cell. The 78 sister chromatids that form 39 chromosomes will each separate at their centromere to form 39 daughter chromosomes in each daughter dog cell.
. 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.
