what determines the specificity of a receptor protein?
Answer:
A working hypothesis is that signaling efficiency/specificity is determined in part by proteins found in the receptor's microenvironment, which together with R, G, and E contribute to the formation of a signal transduction complex at the cytoplasmic face of the receptor.

2. What are the two alleles for flower color in snapdragon?
3. State the Law of Non-Mendelian Inheritance in snapdragon.
Answer:
1
Explanation:
he was able to find chromosomes in plants
Gregor Mendel's research on pea plants led him to the fundamental ideas of inheritance. He came to the conclusion that genes are inherited as distinct, paired units from each parent.
What is Non-Mendelian Inheritance?
Inheritance of features with a more complicated genetic base than one gene with two alleles and total dominance is referred to as non-Mendelian inheritance.
One allele may not always be dominant over another, resulting in a phenotype that falls between the two parents in certain people.
Incomplete dominance is the name given to this inheritance pattern. Snapdragon flowers, for instance, exhibit partial dominance.
When both alleles are present at the same time, this pattern of inheritance is referred to as partial dominance, since neither allele is totally dominant over the other.
Therefore, red and white snapdragons cross to produce exclusively pink progeny.

Answer:
Cytokinesis in plant cells involves the formation of the insertion of a new cell wall that separates daughter nuclei after mitosis
Cytokinesis involves the formation of the insertion of a new cell wall that separates daughter nuclei and produce two new daughter cell.
What is cytokinesis ?It is the final stage in the cell cycle, when a new daughter cells is formed from parent cell through the splitting of the cytoplasm and the separation of the two identical cells.
In Stage 1 cleavage furrow is seen where the actin filaments will begin to tighten around the cells, spindle formation occur, t the chromosomes are divided evenly between the two nuclei. The spindle possesses small structures called astral microtubules guide the alignment of the actin filaments along the future cleavage furrow.
In Stage 2 the gathering of the actin filaments occur where some protein called myosin facilitates the pulling of the actin filaments, and formation of contractile ring begins.
In Stage 3 the myosin a motor protein with the help of ATP, it is able to contract the contractile ring, deepening the cleavage furrow, causing the cell to narrow in the middle as two daughter cells form.
In Stage 4 the actual breaking of the cell membrane and the membrane quickly refuses at the broken point and two independent and identical daughter cells are produced.

Which layer of the
earth has the greatest
density? Why?
Answer: metal inner core
Explanation:
It is made of the densest components & it is under the greatest compression; due to the overlying layers.
The inner core of Earth has the greatest density due to:
- The inner core is made of solid iron and nickel
- The inner core gets consolidated due to pressure exerted by the other top layers.
What are the different layers of the Earth?
Generally the Earth is made of three different layers:
- Crust- The outer layer
- Mantle - The Middle Layer
- Core - The Inner Layer.
Crust:
Outer layer of the Earth and is thin, brittle and cold compared to other layers.
It is majorly made of light elements especially silica, aluminum and oxygen.
The thickness of crust varies for for land and ocean where the former is thicker than latter.
Mantle:
It is around 3000 km thick and is the thickest layer of the Earth. It starts mere at 30 km from the earth's crust.
It is majorly made of Iron, Magnesium and silicon and is dense, hot and semi solid.
The upper part of the mantle is liquid in nature called as Asthenosphere and it is believed that tectonic plates rides upon here and slide across.
Core:
Core is further divided into Outer core and Inner core.
Outer core is made of iron and nickel and is liquid in nature. It is heated largely by the radioactive decay of the elements of the uranium and thorium and this liquid churn huge turbulent current.
Inner core is a solid metal ball having radius of 1220 km. It is extremely dense and is mostly made of iron and nickel.
The temperature of inner core is similar to that of the surface of sun along with high amount of pressure.
Thus this layer has the greatest density amongst all the layers of the Earth.

An experiment that can determine if an object is a living thing by taking a small sample to see if it is made of cells using a microscope. Thus, the correct option for this question is A.
What are the characteristics of living things?The characteristics of living things are as follows:
They have a tendency to construct a balance from the surrounding atmosphere through the process of homeostasis. They have the capability to grow, reproduce, and adapt to the surrounding environment. They perform an act of breathing and move from one place to another. They require food in order to derive energy.A Microscope is a laboratory instrument that is remarkably utilized in order to visualize small objects or cell samples that are too small to examine with unaided eyes. So, any living organism is definitely made of cells that are easily distinguished with the help of a microscope.

How does the evolution of resistance in bacteria affect humans
Answer:
Bacteria, not humans or animals, become antibiotic-resistant. These bacteria may infect humans and animals, and the infections they cause are harder to treat than those caused by non-resistant bacteria. Antibiotic resistance leads to higher medical costs, prolonged hospital stays, and increased mortality.

In a hypothetical population of butterflies, a dominant mutation in an allele that controls wing color has resulted in purple spots developing on the wings. The genetic change is heritable such that the offspring of butterflies who inherit at least one mutated allele will develop purple spots. The population of butterflies inhabits a windy field that contains many purple flowers. Individuals with purple spots are so well camouflaged on the purple flowers that they are eaten less frequently by predators. There are other fields with populations of the same species of butterfly nearby, but purple flowers are less prevalent in these nearby habitat areas. There are no borders between these fields and it is common for individuals from one population to be blown into another population by the wind. Despite the advantage the mutated allele confers to the butterflies in the field with many purple flowers, the mutated allele never occupies 100% of the gene pool and the population of butterflies always contains a mix of individuals with and without purple spots. What is the most likely explanation for why this trait does not spread entirely throughout the population
The movement of alleles into a population is called gene flow. The most likely explanation for why this trait does not entirely spread in the population is 'outside alleles enter the population through gene flow'.
Gene flow is caused by the migration and further reproduction of individuals in the population, or the transport of gametes from one population to another (e.g., the transport of pollen by pollinating bees).
Gene flow is an evolutionary force capable of modifying allele frequencies in a population.
In this case, despite the evolutionary advantage that the mutated allele confers to the butterflies, the frequency of this allele can not reach 100% due to the continued introduction of alleles from other populations (i.e., due to gene flow).
