The best clue that can be used to decide living thing or not a living thing is the observation of living or dead cells present in the specimen. All the living or dead organisms exhibit cells. Cell is a structural and functional unit of life. The growth and metabolism of living organism are dependent upon a cell. A cell in a life form exhibit organelles and components which are not found in non-living objects
The BEST clue you could use to decide: living thing or not a living thing- is option C. is it made of cells and
The living things have some basic characteristic features of life in them that help in determining if an object or thing is living or nonliving thing. these characteristic can be present in all or some, are as follows:
Cellular organization - made of cell is very basic trait of life of every living being.the ability to reproduce - it is present in almost every living thing it could be sexual or asexual.growth & development - living things grow and developenergy use - use energy to perform various functionshomeostasis - regulate according the environmentGenetic material : it can have DNA as genetic materialthus, there is two options only that present in every living organism that are made of cells and presence of DNA, but for DNA one need to investigate thoroughly so the correct answer is - C) Is it made of cells?

A cell has two pairs of submetacentric chromosomes, which we will call chromosomes Ia, Ib, IIa, and IIb (chromosomes Ia and Ib are homologs, and chromosomes IIa and IIb are homologs). Allele M is located on the long arm of chromosome Ia, and allele m is located at the same position on chromosome Ib. Allele P is located on the short arm of chromosome Ia, and allele p is located at the same position on chromosome Ib. Allele R is located on chromosome IIa and allele r is located at the same position on chromosome Ib. Allele G is located on the long arm (q arm) of chromosome Ia, and allele g is located at the same position on chromosome Ib. Allele N is located on the q arm of chromosome IIa and allele n is located at the same position of chromosome IIb.
Required:
a. Draw these chromosomes, identifying genes R, r, G, g, N, and n as they might appear in metaphase I of meiosis. Assume there is no crossing over.
b. Taking independent assortment and the subsequent random separation of chromosomes in anaphase I, draw the chromosomes, with genes identified, present in all possible gametes that could result once this cell completes meiosis. As above, assume there is no crossing over. Explain in your own words what is meant by independent assortment.

During metaphase I, homologous pairs together migrate to the equatorial plane, where they randomly aline with their kinetochores facing opposite poles. The random arrangement of tetrads is different in every cell going through the meiosis process. There is no equal alinement between two cells. When tetrads aline in the equatorial plane, there is no predetermined order for each of the homologous chromosomes of each tetrad to face one of the poles and then migrate to it while separating. Any chromosome of the homologous pair might face any of the poles and then migrate to it. Each of the chromosomes has two possibilities for orientation at the plane. When the new haploid cells are formed, the number of variations in each cell is also different and depends on the chromosomes that form that cell. This random order in the equatorial plane is what introduces variation into the gametes. It is almost impossible that two gametes resulting from meiosis will get the same genetic charge.
B). Taking independent assortment and the subsequent random separation of chromosomes in anaphase I, draw the chromosomes, with genes identified, present in all possible gametes that could result once this cell completes meiosis. As above, assume there is no crossing over. Explain in your own words what is meant by independent assortment.
Independent assortment occurs when the alleles of two or more different genes distribute in the gametes independently from each other. In other words, a gamete receives an allele from a gene that does not depend on nor influence the allele of another gene in the same gamete. This can only be applied to independent genes. An organism gets only one of the members of the chromatids pair of each parent.
During gamete formation in meiosis, the pairs of homologous chromosomes separate after crossing over, and then chromatids sisters also separate, resulting in the formation of four gametes. Each gamete has different information from the combination of homologous chromosomes belonging to the father and to the mother.
There are four possible combinations, considering that there is no crossing over.
Gamete 1: GNRGamete 2: GnrGamete 3: gNRGamete 4: gnr
How “Competition in an ecosystem” is playing a role in life?
Answer:
Competition is an interaction between organisms or species in which both the organisms or species are harmed. Limited supply of at least one resource (such as food, water, and territory) used by both can be a factor.
Explanation:
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.
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 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.

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
