Answer:
Option B, Co-dominance
Explanation:
This is an example of codominance inheritance pattern.
When two alleles representing two different characteristic traits are expressed equally in the offsprings resulting from a cross, then this genetic inheritance pattern is called as codominance .
For example -
A red flower with genotype "RR" is crossed with a white flower "rr" resulting into pink color offsrping with genotype "Rr"
Here, both the red and white traits of flower color are expressed equally thereby giving pink color to the offspring flower.
The same thing is happening in case of true breeding black and white mice.
Hence, option B is correct
The first one, ii. Natural selection and the formation of inseticide resistant insects or antibiotic resistant bacteria.
This can be explained in very simple way. As we all know, natural selection works in a way that only that adapted living beings are going to survive through a specific environment, whether it's because they can grab their food without too much work, or even that they can adapt to the weather. When we use inseticide, we are killing lots of non-resistant insects, and what's left are those that are resistant to this inseticide, and they'll reproduce again, and again we'll go through the same process, but remember, this insect is now stronger and more resistant that before.
The second case, iii. speciation and isolation give three examples how it may occur.
Well. the allopatric speciation and isolation will happen when theres a geographic barrier between one species. This one then is divided into two diffent habitats, but what can divide than could be a mountain, a tree, a river, a rock, anything. And this could be too called as a geographic isolation, because in this new environment, species are going to develop in a different way.
Answer:
The mass
Explanation:
The gravitational field of an object with mass increases as its mass increases. So, a larger object, like the earth, has a stronger gravitational field than a smaller object, like the moon.
There are more factors that may play into this however.
It disconnects the brain's dopamine system.
Further explanation
Cocaine
Cocaine is a capably addictive stimulant medication. For a great many years, individuals in South America have bitten and ingested coca leaves which is source of cocaine, for their stimulant effects. In the mid-1900s, refined cocaine was the primary dynamic fixing in numerous tonics and elixirs created to treat a wide assortment of diseases and was even a fixing in the early plans of Coca-Cola. Prior to the advancement of manufactured specialists utilized cocaine for the relief of pain. However, examine has since demonstrated that cocaine is an effectively addictive substance that can change cerebrum structure and capacity whenever utilized over and over.
Functions of cocaine
It shows very quickly effect after a solitary portion and vanish inside a couple of minutes to 60 minutes. Limited quantities of cocaine for the most part make the person feel euphoric, enthusiastic, loquacious, rationally caution, and easily affected to sight, sound, and contact. The medication can likewise briefly diminish the requirement for sustenance and sleep. Some clients find that cocaine encourages them perform straightforward physical and scholarly assignments all the more rapidly, in spite of the fact that others experience the contrary impact.
Effect of cocaine on dopamine
Cocaine particles block the dopamine transporters which shut down the neuron's capacity to take-up the additional dopamine inside the synaptic parted. This outcomes in expanded degrees of the synapse dopamine present in the extracellular spaces among these neurons.

Formed tiny polypeptides known as Proteinoids when they gathered in little pools.
<h3>What is a polypeptide and how does it work?</h3>
Polypeptides. By joining many amino acids together, polypeptides contribute to the creation of proteins. When two or more polypeptides are joined together to form a protein, the resulting structure is unique to that protein.
<h3>What conclusions did Sidney Fox's experiment reach?</h3>
In the 1950s, Sidney Fox demonstrated that when amino acids were splashed in hot, dry circumstances, they immediately polymerized into proteins. Other studies that used cyanide, clays, and heat to cause the polymerization of amino acids into proteins were effective.
