Active transport and facilitated diffusion are two different mechanisms of moving substances across a cell membrane, with key differences in energy requirement, direction of movement, and specificity.

What is an active transport ?

Active transport is the movement of molecules or ions across a membrane against their concentration gradient, which requires energy in the form of ATP (adenosine triphosphate). Active transport can move substances from an area of low concentration to an area of high concentration, and it is often used by cells to maintain concentration gradients and perform functions like nutrient uptake and waste removal.

Facilitated diffusion, on the other hand, is the passive movement of molecules or ions across a membrane with the help of transport proteins. Facilitated diffusion moves molecules or ions from an area of high concentration to an area of low concentration, following the concentration gradient, and does not require energy input from the cell. Facilitated diffusion is often used to transport large or charged molecules that cannot diffuse across the membrane on their own.

Another key difference between active transport and facilitated diffusion is specificity. Active transport requires specific transport proteins, called pumps, that are designed to move specific molecules or ions. In contrast, facilitated diffusion can use a variety of transport proteins that are specific to certain molecules or ions, but can often transport a range of similar molecules.

In summary, the main differences between active transport and facilitated diffusion are that active transport requires energy input and can move substances against their concentration gradient, while facilitated diffusion is passive and moves substances along their concentration gradient. Additionally, active transport requires specific transport proteins and can be highly selective, while facilitated diffusion is less selective and can use a variety of transport proteins.

The gram reaction is an important tool for identifying bacterial species based on their cell wall composition. The gram-positive bacteria have thick peptidoglycan cell walls that stain purple with the crystal violet stain, while the gram-negative bacteria have thinner peptidoglycan cell walls and an outer membrane that stains pink with the counterstain safranin.

For the physician, the gram reaction can help guide antibiotic therapy since gram-positive and gram-negative bacteria are often susceptible to different classes of antibiotics. Knowing the gram reaction of a bacterial species can also help the physician determine the likely pathogenicity of the bacteria and the severity of the infection.

For the laboratory technician, the gram reaction is an important initial step in bacterial identification. It can help narrow down the possible bacterial species and guide further testing. Additionally, the gram reaction can provide important information about the bacterial cell wall, which can be useful in understanding the bacterial physiology and in developing new antibiotics.

Assuming a single diallelic gene coding for each trait, expressing complete dominance, and with no interaction between genes, the most probable genotypes of the parents are BbRr. Both parents must be dihybrids.

In this example, two features are considered,

After the cross, the results of the progeny were as follows,

Total number of pigs among the progeny = 19 + 6 + 7 + 1 = 34 pigs.

We will assume that of these traits are coded by a single diallelic gene each, that express complete dominance, and do not interact with each other.  

If we perform a cross considering this two genes, we will expect to get 16 possible combinations of the parental gametes.  

So, the 34 pigs from the progeny are included in these 16 possible genotypes.

34 pigs ---------------------- 16 combinations

19 black and rough ----- X = (19 x 16) / 34 = 8.94 ≅ 9

6 black and smooth ----- X = (6 x 16) / 34 = 2.82 ≅ 3

7 white and rough ------- X = (7 x 16) / 34 = 3.2 ≅ 3

2 white and smooth ----- X = (2  x 16) / 34 = 0.94 ≅ 1

So, by looking at the phenotypic proportions of the progeny, we can suggest the possible parental genotypes.

Phenotypic proportion

These proportions are the result of a cross between two dihybrid individuals, meaning that both parents are heter0zyg0us for both traits.

Also, according to these numbers, we can tell that the dominant traits are black and rough over white and smooth, respectively.

So let us make this cross assuming two dihybrid parents,

Parentals) BbRr    x    BbRr

Gametes) BR, Br, bR, br

                 BR, Br, bR, br

Punnett square)         BR          Br        bR         br

                       BR     BBRR    BBRr    BbRR    BbRr

                       Br      BBRr     BBrr      BbRr     Bbrr

                       bR      BbRR    BbRr    bbRR     bbRr

                       br       BbRr     Bbrr     bbRr       bbrr

F1) Genotypes

Genotypic ratio ⇒ 1:2:1:2:4:2:1:2:1

     Phenotypes

Phenotypic ratio ⇒ 9:3:3:1

In conclusion, The most probable genotypes of the parents are BbRr, being dihybrid both of them.

Explanation:

Orcus is a plutino, a trans-Neptunian object that is locked in a 2:3 resonance with the ice giant Neptune, making two revolutions around the sun to every three of Neptunes. This is much as pluto, except that the phase of Orcus's orbit is opposite from Pluto's: Orcus is at aphelion when pluto is at aphelion when Pluto is at perihelion and vice versa. This was a major consideration in selecting its name, as deity Orcus was the Etruscan equivalent of the Roman Pluto, and later becamean alternate name for Pluto

Family of KBOs orcuas belongs to plutino, it is a plutino object revolves around the sun.

Orcus is a plutino, a trans-Neptunian object that revolves about the sun twice as often as Neptune and is locked in a 2:3 resonance with it.

This is quite similar to Pluto, but Orcus's orbital phase is the opposite of Pluto's, Orcus is at aphelion while Pluto is at perihelion, and vice versa.

This was a key factor in naming it since the deity Orcus was the Etruscan counterpart to the Roman Pluto and eventually developed into a different name for Pluto.

Therefore, revolves around the sun twice as often as Neptune is the plutino is a orcus in the family of KBOs.

Answer:

The answer would be the flowers

Explanation:

The flowers have pollen in or on them that bees, wasps, and butterflies pick up while drinking nectar. The pollen is eggs and is spread from flower to flower.

Flowers is a part of plant to begins the reproductive process to allow the plant to spread and grow new plants.

Pollination, the act of sexual reproduction in flowering plants, is how it happens. Stamens, the male sex organ, and pistils, the female sex organ, are found in flowers.

The portion of the stamen that carries pollen is called the anther. The male gametes are found in pollen. For reproduction to occur, pollen must be transferred to the stigma, a region of the pistil.

When a plant's own pollen nourishes its own ovules, self-pollination occurs. When animals or the wind carry pollen from one plant to another, cross-pollination occurs.

Cross-pollination has the benefit of preserving a species' genetic diversity. When environmental conditions change and organisms must adapt, genetic variety is useful. Some plant characteristics really work to stop self-pollination.

Therefore, Flowers is a part of plant to begins the reproductive process to allow the plant to spread and grow new plants.

The stages of bee development are egg, larva, pupa, and adult. Eggs hatch into larvae, which then transform into pupae. Finally, adult bees emerge and undergo further maturation.

The stages of bee development are:

1. Egg: The bee life cycle begins when the queen bee lays an egg in a honeycomb cell.

2. Larva: The egg hatches into a larva, which is a legless, grub-like creature. The larva is fed a special diet called royal jelly, which stimulates its growth.

3. Pupa: The larva undergoes metamorphosis and transforms into a pupa. Inside the sealed cell, the pupa undergoes various changes, developing into an adult bee.

4. Adult Bee: After completing the pupal stage, the fully developed adult bee emerges from the cell. The bee then undergoes further maturation, such as its exoskeleton hardening, wings expanding, and adult coloration appearing.

It's important to note that there are three castes of bees: queen, worker, and drone. The development process for each caste is similar, but the diet and size of the cells they are raised in differ, leading to their distinct roles within the colony.
