Bacteria reproduces asexually and produce genetically identical offspring. They produces a large number of offspring quickly and all will be uniform.

Binary fission is the asexual method of reproduction in  bacteria. Asexual reproduction creates clones of the original parent, which results in kids that are genetically identical to the parent.

Asexual reproduction allows for the rapid production of vast numbers of children by a single person. Asexual reproduction is a successful method of reproduction in a stable or predictable environment since all the children will be suited to that environment.

Asexually reproducing organisms may be at a disadvantage in an unstable or unpredictable environment since all of the progeny are genetically similar and might not have the genetic diversity to survive in new or changing settings.

Answer:

6.45 g of iodine, I₂

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

Zn + I₂ —> ZnI₂

Next, we shall determine the mass of Zn and I₂ that reacted from the balanced equation. This can be obtained as follow:

Molar mass of Zn = 65 g/mol

Mass of Zn from the balanced equation = 1 × 65 = 65 g

Molar mass of I₂ = 127 × 2 = 254 g/mol

Mass of I₂ from the balanced equation = 1 × 254 = 254 g

SUMMARY:

From the balanced equation above,

65 g of Zn reacted with 254g of I₂.

Finally, we shall determine the mass of f I₂ needed to react with 1.65 g of Zn. This can be obtained as follow:

From the balanced equation above,

65 g of Zn reacted with 254g of I₂.

Therefore, 1.65 g of Zn will react with = (1.65 × 254)/65 = 6.45 g of I₂.

Thus, 6.45 g of iodine, I₂ is needed for the reaction.

Explanation:

Answer: 0.045 moles of [tex]F_2[/tex] will be required to  produce 3.0 grams of  [tex]KrF_6[/tex].

Explanation:

To calculate the moles :

[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]    

[tex]\text{Moles of} KrF_6=\frac{3.0g}{198g/mol}=0.015moles[/tex]

The balanced chemical equation is:

[tex]Kr+3F_2\rightarrow KrF_6[/tex]  

According to stoichiometry :

1 mole of [tex]KrF_6[/tex] is produced by = 3 moles of [tex]F_2[/tex]

Thus 0.015 moles of [tex]KrF_6[/tex] will be produced by=[tex]\frac{3}{1}\times 0.015=0.045moles[/tex]  of [tex]F_2[/tex]

Thus 0.045 moles of [tex]F_2[/tex] will be required to  produce 3.0 grams of  [tex]KrF_6[/tex].

In Chemistry, there are four (4) main types of sublevel and these includes:

However, it is impossible for any atom of a chemical element to have a 2d orbital because electrons are generally located in the s and p orbitals (sublevels) in the second energy level.

In chromatography,when all the three samples have atleast one substance common it is indicated by Rf values which are same for the 3 samples as they have one substance common in them.

Chromatography is a separation technique which is generally used for separating substances  based on their solubilities. The technique makes use of two phases the mobile phase and the stationary phase.

The components are separated from each other based on their solubility in the mobile phase. Component which is least soluble does not travel along the mobile phase while component which is highly soluble travels with the mobile phase.

The difference in the solubility of the components is measured with the reference to the solvent front and is expressed in terms of Rf value.

coevolution

Explanation:

Coevolution plays a key role in shaping the biodiversity on Earth. Coevolution is commonly defined as reciprocal evolutionary changes brought about by interactions between species, implying that interacting species impose selection on each other(Science direct).

We can see that the change that occurred in the plants of the tropical rainforests is closely related to their link to birds. The fruits evolved an attractive color so that birds, having evolved to eat the brightly-colored fruits, may eat them.

Answer:

Let’s get back to simple physics and the laws of motion. Your car and everything in it are traveling in a given direction, to stop in requires force be applied in the opposite direction over a period of time. This occurs extremely quickly in an accident and the force is greater because the time the opposing force is acting on the vehicle is very short. The airbag system is designed to offer you protection from the violent forces exerted on you during an accident.

There are three main components to your airbag system, the bag, the inflator and the sensor. The sensor must register a collision force roughly equal to hitting a brick wall at 10 to 15 mile per hour before it will trigger the airbag inflation. Once tripped the airbag system inflates through a chemical reaction between sodium azide (NaN3) and potassium nitrate (KNO3) which creates nitrogen gas. An igniter is set off which quickly burns the chemical fuel and creates the gas needed for expansion. The bag then blows out of its storage in a split-second. Immediately after inflation, when the chemical burn is complete, the airbag begins to deflate as the gasses escape from holes in the fabric.
