Pollinization is the transference of pollen grains to the stigma. Fertilization occurs when pollen grains move to the ovary and gametes meet. Option D. 2,3,4,1
What is pollinization?
Pollinization is the pollen transference from the masculine organs to the feminine organs of the flower. It might involve the same flower or different flowers, the same plant or different plants.
What are the Feminine reproductive structures?The central structure is known as a carpel, also recognized as the pistil.The base of the carpel forms the ovary, in which the eggs are produced and where the zygote develops.The opposite extreme of the carpel is the stigma, in the superior part. The stigma is a sticky surface where the pollen grains get attached.The style is the filament structure that connects the ovary and the stigma.What are the Masculine reproductive structures?The pollen grains, or male séx cells, are produced in the stamens.The stamen has an anther where the pollen is produced, and a filament that provides support.What is fertilization?Fertilization is the gamete fusion, which involves the mature germinated pollen grain and the ovule.
During fertilization
1) The mature pollen grains are driven to the stigma of the same flower or other flowers of the species, where they stick.
2) Once in the stigma, the pollen grain germinates.
3) A thin structure named pollinic tube forms. It goes from the stigma along the style and ends in the flower ovary.
4) The pollen grains move along the tube forward to the ovary, where they meet the egg and fertilize.
5) Once in the ovary, the pollen grains get in touch with the ovule. They have double fertilization.
6) The zygote develops in the ovary.

Which property of water allows it to dissolve substances like sodium Which property of water allows it to dissolve substances like sodium chloride and glucose but prevents it from dissolving lipids?
A. pH
B. polarity
C. adhesion
D. cohesion
Polarity is an intrinsic property of water associated with its behavior to dissolve substances like sodium chloride and glucose.
What is polarity?It is a property of high importance because it defines the behavior of these related to other properties.
It represents the unequal electrical charges in the same molecule, said unequal splitting of electrons makes water a polar molecule.
Therefore, we can conclude that polarity is an intrinsic property of water associated with its behavior to dissolve substances like sodium chloride and glucose.

Ducks are aquatic birds. Their feet are webbed and this trait makes them fast swimmers. Biologists believe that ducks evolved from land birds, which did not have webbed feet. How could this have happened
Answer:
Random chance mutations led to the webbed feet trait in ancestral land birds, conferring them an adaptive advantage. Birds that inherited the beneficial random mutations associated with the webbed feet trait had more chances to survive and reproduce, passing this trait to the next generations.
Explanation:
Mutations are ramdom changes in the nucleotide sequence of the genome of a particular organism. In general, mutations are deleterious, but mutations may occasionally be beneficial in certain environments. A beneficial mutation must be associated with one or more phenotypic traits capable of conferring an adaptive advantage in a certain environment, thereby the individuals carrying the mutation have more chances to reproduce and survive. In this case, one or more beneficial mutations associated with the webbed feet trait passed to the next generations, increasing their frequency in the population.

Which of the following distinguishes how auxins affect plant stems?
Auxins enable plant stems to search for water.
Auxins give plant stems their strength and rigidity.
Auxins enable plant stems to reach for sunlight.
Auxins give plant stems their green pigmentation.
Answer:
D.
Explanation:
Answer:
b
Explanation:
Auxins promote stem elongation, inhibit growth of lateral buds (maintains apical dominance). They are produced in the stem, buds, and root tips. ... This produces a curving of the plant stem tip toward the light, a plant movement known as phototropism. Auxin also plays a role in maintaining apical dominance.
1. Explain how the atomic number and mass number of an atom can be used to determine the number of
electrons and of neutrons respectively.
Because the total of neutron and proton/electron is the atomic mass. So if you wanna find proton/electron and you know the neutron, just minus the atomic number with the neutrom and you will get the proton
Here if you need the formula
Atomic number = Total neutron + Total proton or electron

Explanation:
Enzymes can be regulated in a multitude of ways. One such way is by covalent modification, in which functional groups are attached to or removed from the enzyme. One such functional group that can be added to an enzyme is a phosphate group. Depending on the enzyme, addition of a phosphate group may increase or decrease that enzyme's activity. Which of the following is the general name of an enzyme that functions to add phosphate groups to its substrate?
a. Oxidoreductases
b. Ligases
c. Hydrolases
d. Isomerases
e. Transferases
Answer:
Option E
Explanation:
Transferase enzyme are able to transfer a molecule or atom from one compound to the other.
For example – In the process of phosphorolysis, add phosphate to the substrate group .
X-Y + Z = X + Z-Y
Here Z in the phosphate group
Hence, option E is correct

A new human species was found on a distant planet, whose genetic inheritance and process of reproduction is identical to that of humans on earth, however, their phenotypes are much different. You are tracking two phenotypes in this new species: eye shape and tail size. The single gene that controls eye shape (gene E) is unlinked from the single gene that controls tail size (gene T). Square eyes is the dominant eye shape and round eyes is the recessive eye shape. Long tail is the dominant tail size and short tail is the recessive tail size.
Required:
An individual of this new species is heterozygous for gene E and heterozygous for gene T. What is their genotype and phenotype?
Answer:
The individual has the genotype Ee (for the eyes) and Tt (for the tail) and has square eyes and a long tail.
Explanation:
If an individual is heterozygous, it means that he has a dominant allele and a recessive allele for each genotype. In this case, if the individual is heterozygous for the E gene, he has the genotype formed with the "Ee" alleles. If the same individual is heterozygous for the T gene, it has the genotype formed by the "Tt" alleles.
Individuals with heterozygosis will present phenotypes related to the dominant allele, since the recessive allele is only expressed in hom0zygosis. In this case, the individual will have the phenotype square eyes and long tail.
