How dose the process of photosynthesis create food
Answer:
Plants, like all living things, need food to survive. Plants make their food using a process called photosynthesis, which means “putting together through light.” During photosynthesis, a plant traps energy from sunlight with its leaves. It also takes up water from its roots and carbon dioxide gas from the air.

of a cloud.
C. Electrons flow from an outlet into a toaster, causing it to heat a
slice of bread.
D. A person rubs a shoe on a rug, causing extra electrons to be
transferred to the shoe.
Answer:
The correct example of current electricity is C. Electrons flow from an outlet into a toaster, causing it to heat a slice of bread.
Explanation:
Current electricity refers to the flux of charged particles through a conductor material per unit of time. In general, when we refer to electric current we are talking about the electron flux. Electric energy originates from the difference of electrical potential between two points when they get in contact through a conductor. This contact provokes an electrical current that consists of the transmission of negative charges called electrons through conductor materials such as metals from the source of generation to the point of consumption.
In the exposed example, the source of electrons is the outlet, while the point of electron consumption is the toaster. In this last artifact, electrical energy is transformed into heat to toast the bread.

What do you mean by aerobic cellular respiration?
Cellular respiration is up two types such as aerobic and anaerobic.
Aerobic Cellular Respiration is the process by which glucose is and oxygen are used to synthesize CO2, H2O and 36 ATP.
It occurs in the cytoplasm and mitochondria of the cell.
It has four steps such as Glycolysis occurs in the cytoplasm where breakdown of glucose occur and make 2 ATP.
The Intermediate Step take place in mitchondria where 3 carbon pyruvic acid molecules are converted to 2 carbon molecules.
Third step is the Kreb's Cycle occurs in the mitochondria where 2 ATP and Hydrogen ions are collected.
Finally, the Electron Transport Chain occurs in the cristae of the mitochondria make approximately 28-32 ATP.
Thus option A is correct.

Animals that live on intertidal rocks often exhibit compressed or dorsally flattened bodies. this is an adadptation that protects against:______
a. sunlight
b. high temperatures
c. desiccation
d. wave shock
e. predation
Answer:
d. wave shock
Explanation:
An adaptation can be defined as a phenotypic trait that makes an organism and/or species better suited to its environment, thereby this organism/species will have more chances to survive and reproduce in such conditions. Rock-dwelling aquatic animals have different ecological, morphological and behavioral adaptations to survive in this type of environment. In this regard, it is well-known that these organisms show dorsally flattened bodies, since it is one fundamental morphological adaptation which helps them to dissipate the force of the waves.

4. Discuss the sense organs of cnidarians
Answer:
To tell the truth I don't know what none of this stuff so I searched it up.
Explanation:
Cnidarian sense organs are thought to be exclusive to the medusa, a point we dispute subsequently. Nevertheless, the sense organs of the medusa are highly developed and distributed across Scyphozoa, Hydrozoa, and Cubazoa. In those hydrozoans with a medusa stage, many have eyes associated with the tentacle base.
Hope that is what you are looking for.
Answer:
he rhopalium, the sense organ bearing structure of Scyphozoa, as well as the Cubozoa (a modified group within the scyphozoans), contains the statocyst and eyes. It is borne on the margin of the bell in the medusa. The rhopalia of cubozoan medusae contain eyes with lenses, the most dramatic of cnidarian sense organs.

If an organism has a diploid number of 50, and one of its cells undergoes meiosis, what is
the number of daughter cells and how many chromosomes will each one have?
Answer:
for me
Explanation:
it's 25
because di is 2 and ha is 1
If an organism has a diploid number of 50, and one of its cells undergoes meiosis, then the number of daughter cells produced by this cell is four and each contains 25 chromosomes.
What is Diploid?Diploid may be defined as a condition that determines the existence of two complete sets of chromosomes in an organism's cells, with each parent contributing a chromosome to each pair.
On contrary, haploid cells generally contain only a single set of chromosomes. These types of cells are formed due to the process of meiosis, while diploid cells are formed by the activity of mitosis.
According to the question, if a diploid number of an organism = 50.
This means that 2n = 50,
n = 25.
As we all know that when a cell undergoes meiosis, it will definitely have half the amount of genetic content in its daughter cells.
Therefore, if an organism has a diploid number of 50, and one of its cells undergoes meiosis, then the number of daughter cells produced by this cell is four and each contains 25 chromosomes.

In humans, freckles (F), widow’s peak (W) and attached earlobes (E) are all unlinked dominant traits. A man with freckles, widow's peak and attached earlobes marries a woman with freckles, straight hairline, and attached earlobes. Their first child has no-freckles, straight hairline, and detached earlobes. What is the probability that their second child has no-freckles, straight hairline, and attached earlobes? Select one:
Answer:
The correct answer is - 3/32.
Explanation:
We know that freckles F is dominant over no freckles f, similarly, Widow's peak W is dominant over straight hairline w and attached earlobes are dominant over free earlobes.
So, the combination of alleles for each phenotype would be:
No freckles = ff , Freckles = FF, Ff
Free earlobes = ee , Attached earlobes = EE, Ee
Straight hairline = ww , Widow's peak = WW, Ww
In the question, it is given that the first child has no-freckles, straight hairline, and detached earlobes that would be - ffwwee genotype and as it is given that all alleles are in recessive which means both parents must have recessive alleles.
So, the correct genotype of the man will be FfWwEe and the woman will be FfwwEe.
(man = freckles, widow's peak, and attached earlobes (F_W_E_) and woman = freckles, straight hairline, and attached earlobes (F_w_E_))
then cross between: FfWwEe × FfwwEe
The probability of the freckles and no freckles would be-
Ff × Ff = 3/4 freckles, 1/4 no freckles
The probability of the widows and straight hairline would be-
Ww × ww = 1/2 widows peak, 1/2 straight hairline
The probability of the free earlobes and attached earlobes would be-
Ee × Ee = 3/4 attached, 1/4 free earlobes
Combined possibility of all three phenotypes: no freckles, straight, attached would be = 1/4 × 1/2 × 3/4 = 3/32
Thus, the correct answer is - 3/32.

Lupus is a multisystem disease in which autoantibody production can lead to inflammation and tissue
damage in any part of the body. The pathogenesis of lupus is thought to be a combination of
predisposing genetic factors and environmental factors such as medication, or infectious agents that

What is the chromosome number produced in daughter cells as a result of mitosis?
A. 1n
B. 2n
C. 4n
The chromosome number produced in daughter cells as a result of mitosis is the 2n that is in option B, as in this process, the parent cell and the daughter cell contain the same genetic content.
What is the significance of a set of chromosomes?There are different sets of chromosomes in different species such as wheat's genetic contents differ from those of humans because humans have two sets (2n) of chromosomes, whereas some plants have tetraploid sets of chromosomes. The number of chromosomes remains constant after cell division in mitosis, and the cell gets the exact same copy in mitosis, which is 2n in the case of the human, as humans have a 2n set.
Hence, the chromosome number produced in daughter cells as a result of mitosis is the 2n that is in option B, as in this process, the parent cell and the daughter cell contain the same genetic content.
