Answer: If the area of observation in the experiment had not been restricted to the area of the root tip that is actively dividing, then the results of the experiment would have been different because the cells would supposedly be spending their entire existence in inter-phase.
If your observation had not been restricted to the tip of the onion root, how would the results be different - The only difference is that chromosomes are only visible in that of dividing cells that are meristematic cells.
Meristematic cellsTip of the onion root is meristematic cellit divides but if it is a permanent cell then here would be no divisionmeristematic cells are responsible for the growth of the plant stem and roots which is essential for the development of the plant.
Thus, If your observation had not been restricted to the tip of the onion root, how would the results be different - The only difference is that chromosomes are only visible in that of dividing cells that are meristematic cells.

Why do plants have rigid barks
Answer:
Bark is the outermost covering of a tree's trunk and branches, like a protective skin. Tree bark conserves water and also serves to protect the tree's essential living systems from environmental and situational dangers. These include temperature extremes, storms, attacks by animals, diseases, and insects.
Answer: Woody plants have a tough, waterproof outer layer of cork cells commonly known as bark, which further protects the plant from damage.

A mother buys a child a toy each time the child behaves in the store. What kind of reinforcement does this behavior exhibit? (Site 1)
Answer: If the mother fails to condition the child the child will be spoiled and will not be able to make good decisions later on in life. Operant Conditioning should be done. Thus, the child should be given toys as rewards for something good such as high grades at school. While on the latter, a punishment should be provided if the child does something that is not right.

True or false. A paper clip cannot become magnetic and pick up other paper clips no matter the circumstances
Answer:false
Explanation:
A paper clip can become magnetic if it exposed to magnetic force that polarizes it
The sentece is false.
The magnetization process consists of magnetizing a material that naturally does not have magnet characteristics.
This process can happen by induction, friction or by the use of an electric current.
So, a paper clip can become a magnetic and pick up other paper clips if this object is magnetized and the sentece is false.

¿Qué efecto tiene para las cadenas tróficas la tala y deforestación de los organismos productores?
Answer:
tiene un efecto devastador sobre las cadena tróficas de ecosistemas terrestres
Explanation:
En una cadena trófica, los organismos productores, también conocidos como autótrofos, son aquellos capaces de convertir la energía proveniente del Sol (organismos fotosintéticos) o de la oxidaxión de compuestos inorgánicos (organismos quimiosintéticos) en nutrientes a través de la formación de enlaces de carbono que componen moléculas orgánicas tales como, por ejemplo, carbohidratos (es decir, celulosa, azúcar, etc). Por ejemplo, los árboles son organismos productores que usan la fotosíntesis para convertir la energía lumínica solar en energía química la cual es utlilizada por consumidores primarios (hervívoros) de la cadena trófica. Los árboles son organismos productores los cuales juegan un papel clave en ecosistemas terrestres, representando la principal fuente de alimento y nutrientes para diferentes consumidores primarios. Además, estos organismos autótrofos son también fundamentales porque generan oxígeno (O2) y capturan el dióxido de carbono (CO2) de la atmósfera, lo cual es un proceso clave para el sostenimiento de la vida en la tierra.

how cells differ from viruses in life cycle and in organelles
"Viruses can't reproduce by themselves, so they are not considered living. Nor do viruses have cells: they're very small, much smaller than the cells of living things, and are basically just packages of nucleic acid and protein."
Celeste and Raymond are studying the differences between prokaryotes and eukaryotes. They learned that in eukaryotic cells The electron transport chain is in a different location then in prokaryotic cells. Which statement give the correct explanation of this difference?
Answer:
See the answer below
Explanation:
Eukaryotic organisms or eukaryotes have nuclei and membrane-bound organelles such as mitochondrion and chloroplasts, unlike prokaryotic cells/prokaryotes.
In eukaryotic organisms, the process of electron transport - a part of the respiratory process - happens in the inner membrane of the mitochondrion through a series of electron carriers.
Because prokaryotes lack mitochondrion, the electron transport chain takes place in the cell membrane as an improvisation.
Hence, the difference in the location of the electron transport chains of eukaryotes and prokaryotes is due to the mitochondrion.
Answer:
B.In eukaryotes, the electron transport chain is composed of a series of electron carriers located in the inner membrane of the mitochondrion.
D.In prokaryotes, the electron transport chain is in the cell membrane.

Answer: I would say d
Explanation:
Water can move with air and color change could be because of the sunlight or chemicals present in the water. Water will change shape according to the container it is in. So d is the best choice because a test can prove that cells belong to a living organism

In Rabbits, black fur (B) is dominant to white (b), and long ears (E) are dominant to short ears (e). What is the expected phenotypic ratio of the offspring of a BBee x bbEE cross if these alleles sort independently?
Answer:
A. 16 black/long ears, 0 black/short ears, 0 White/long ears, 0 White/short ears
Explanation:
This question is a typical dihybrid cross i.e. involving two genes in rabbits. One coding for fur color and the other for ear length. The allele for black fur (B) is dominant to allele for white fur (b) and allele for long ear (E) is dominant to alelle for short ear (e).
In this question, a cross between two rabbits with genotypes: BBee x bbEE is performed. The following combination of gametes will be produced by each rabbit:
BBee - Be, Be, Be, and Be
bbEE - bE, bE, bE, and bE
Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
All BbEe offsprings, which have a black fur and long ear phenotype.
Hence, the phenotypic ratio is 16 black/long ears, 0 black/short ears, 0 White/long ears, 0 White/short ears
Marty's genotype for color blindness was: Question 2 options: XCX XCXC XY XCY
Marty's genotype for color blindness depends on gender. If Marty is a male, then the genotype is [tex]X^ {c}Y[/tex] , but if Marty is a female, then the genotype is [tex]X^{c}X^{c}[/tex] . This color blindness is an X-linked recessive trait.
What is the X-linked trait?There are two types of genes: some are present on the autosomal chromosomes, and some are present on the X and Y chromosomes. The genes that are present on the autosomal chromosomes are called autosomal genes, and the genes present on the X chromosome are called sex-linked genes.
Color blindness is a sex-linked recessive disorder, which means that a male requires only one recessive copy of the gene. The female can be a carrier if she has a single copy, but if she has two copies, she will be infected with this disease.
Hence, if Marty is a male, then the genotype is [tex]X^ {c}Y[/tex], but if Marty is a female, then the genotype is [tex]X^{c}X^{c}[/tex]. This color blindness is an X-linked recessive trait.

What is an adaptation
Answer: To answer the question I see in the screenshot provided, it would be "Variation of traits from sexual reproduction.
To answer the question of what an adaptation is in my own words:
An adaptation is a trait that a species evolves to obtain over a long period of time, due to the competition of resources with other species. This can also be explained with "Survival of the fittest".
Explanation:
What evidence must be considered when determining whether or not a trait is an adaptation:
1) A trait that is an adaptation is always heritable, as in it goes from every parent to every child.
2)An inheritable trait can skip generations, an adaptation cannot.
3) Adaptations are evolved traits that provide a specific function that enables an organism to survive. A longer bird beak allows a bird to obtain more food when easily obtained food is scarce.
4) An adaptation trait must enhance the fitness of an organism. (Fitness refers to whether an organism can produce viable offspring that has better advantages due to the trait)
5) The appearance of the trait and how the species uses the trait must occur at the same time. This shows that the trait was evolved for the purpose for which it's used. A bird with a long beak doesn't need a long beak if food is abundant.
