Taking into account the definition of Avogadro's number, 2 moles of Fe(NO₃)₂ contains 1.2046×10²⁴ molecules.
Avogadro's NumberAvogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance.
Its value is 6.023×10²³ particles per mole. Avogadro's number applies to any substance.
Amount of moles in this caseIn this case, you have 2 moles of Fe(NO₃)₂.
Then you can apply the following rule of three: If 1 mole of the compound contains 6.023×10²³ molecules, 2 moles of the compound contains how many molecules?
amount of molecules= (6.023×10²³ atoms× 2 moles)÷ 1 mole
amount of molecules= 1.2046×10²⁴
Finally, 2 moles of Fe(NO₃)₂ contains 1.2046×10²⁴ molecules.

Suppose that the same island experiences environmental
conditions that prevent the growth of large seeds. What do you think would happen to
the average size of finch beaks? Explain your reasoning.
Answer:
The size of finch's beak depends on the size of seeds.
Explanation:
The average size of finch beaks also changes because the size of finch beak changes according to the size of seed available. If the environment contains large sized seeds so the population of finch having small beak size increases due to food availability while on the other hand, if the region contains large sized seeds so the population of finch having big beak size increases so according to the size of seeds, the size of finch's beak also changes.
genetic engineering might allow parent to 'design' their children before birth are you in favor of this? why or why not?
Answer:
I think it is quite an interesting idea to allow parents to 'design' their children before birth. Because some people have preferences and those preferences are taken very seriously. I wouldn't want to have a baby boy, I would want a baby girl. Although, this could be a waste of money and time because this might be one of the things that are better not to be fixed even if it isn't broken. But, this can also be good, if you desperately need a child with specific features, this can help. Even if I can't seem to find a reason where a child is supposed to have specific features.
Explanation:
The alteration of the natural gene by the tools is called genetic engineering. The application of genetic engineering is to make transgenic animals that give protein-rich products and transgenic plants which are disease-free.
The idea of genetic engineering is quite subjective. some people find it right and some find it wrong. In order to evolve biological science, genetic engineering is important but ethically and morally genetic engineering is not good as we altering nature's work.
Genetic engineering allows a parent to check the genetic disease of the child and help them to cure it but it is ethically wrong if they used it to find the sexual gender of the child.
Hence, genetic engineering is wrong in a limited way.

If a gene has two alleles, there are two possible genotypes.
a. True
b. False
Answer:
b. False
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
Heredity refers to the transfer of traits (specific characteristics) from the parent of a living organism to her offspring through sexual reproduction or asexual production. Some examples of hereditary traits are dimples, tongue rolling, baldness, handedness, freckles, curly hair, color blindness, height, etc.
According to Mendel's Law of Dominance, if a gene has two alleles, there are three (3) possible genotypes.
The three (3) possible genotypes are;
I. A combination of alleles such as AA.
II. A dominant combination (phenotype) such as Aa.
III. A recessive combination such as aa.
Where;
A represents the dominant allelea represents the recessive allele.Also, a single version of a gene expressed by a living organism is referred to as an allele.

These are born in cones and are not visible until maturity.
There are several characteristics of Gymnosperms. They are:
1. They are autotrophic, photosynthetic plants which tend to conserve water.
2. They have vascular system which includes roots, xylem, and phloem that is used for the transportation of water and nutrients.
3. The ovules and seeds of gymnosperms develop on the scales of cones which is in enclosed chambers called ovaries.
4. They are older than angiosperms on the basis of evolution.
They are divided into four classes like

The place where the new volcanoes are less likely to be seen is mid-ocean ridge. The correct option is A.
What is volcano?A volcano is a crack in the crust of a planet, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber beneath the surface.
Volcanoes are most commonly found where tectonic plates are diverging or converging on Earth, and the majority are found underwater.
Although Australia is the only continent with no active volcanoes, it does have one of the world's largest extinct volcanoes, the Tweed Volcano.
Volcanism is directly related to plate tectonics theory. Volcanoes are only found at specific types of plate boundaries, and only rarely in the middle of ocean plates.
Thus, the correct option is A.

B. The amounts of sun, water, and nutrients affect the
growth of a plant
C. Parents with red hair have a child with red hair
D. A red snapdragon flower is crossed with a white
snapdragon flower to produce a pink snapdragon flower.
Answer:
B. The amounts of sun, water, and
nutrients affect the growth of a plant
Explanation:
Gene expression is the way by which the genes of an organism instructs the production of proteins, which are responsible for the organism's phenotype. However, the trait or characteristics possessed by organisms are not strictly or 100% dependent on the genotypic factors but also on the environmental factors.
Environmental factors are the biotic (living) and abiotic (non-living) factors that affect organisms development and growth. An example is how the amount of sun, water, and nutrients, which are all environmental factors, affect the growth of a plant. Growth in plant, therefore, affects gene expression.

Answer: C....Convection currents play a role in the movement of Earth’s inner core
The statement which is not correct with regard to convection currents is as follows:
Convection currents play a role in the movement of Earth’s inner core.Thus, the correct option for this question is C.
What is Convection current?Convection current may be defined as a procedure that significantly involves the movement of energy from one place to another. It is basically the existence of current in a fluid through convection.
The inner core of the earth has appeared as solid as compared to other parts like the crust and mantle. Most liquid particles are definitely found on the mantle of the earth's surface.
Due to the presence of excessive liquid particles and compounds, the convection current is significantly noticed there.
Apart from this, magma is also a fluid that derives current through convection. It produces in a number of ways like magma driving plate tectonics, density differences in the magma, and temperature differences.
Convection currents are basically the movement of fluid with respect to temperature or density difference within the material.

The lineage of pea plants produced round seeds for four generations. The plants that fertilized these pea plants also produced round seeds. However, in the fifth generation, the plant produced to two plants with wrinkled seeds. Can that be possible? Explain your answer using your pedigree chart.
Answer:
Explanation:
This happened because two fully recessive plants where introduced into the lineage. these plants where paired with the dominate verison. this would make all of the offspring have the two traits. this being said it would make it possible for the offspring to be Wrinkled Seeds.
When two heter0zyg0us individuals are crossed -simple d0minant inheritance-, or a heter0zyg0us individual is crossed with a h0m0zyg0us recessive one, they can produce h0m0zyg0us recessive subjects among the progeny. Heter0zyg0us individuals among the fourth generation got crossed with another plant (h0m0zyg0us recessive or heter0zyg0us) and produced two h0m0zyg0us recessive plants expressing wrinkle seeds.
---------------------------
The first step is to understand the given information. So,
The first four generations produced round seedsPlants that fertilized these plants also produced round seeds (see generation II) Among the fifth generation there are two plants with wrinkled seedsLet us assume that a diallelic gene determines the shape of seeds.
D0minant allele R codes for round seedsRecessive allele r codes for wrinkle seedsNow, let us analyze the pedigree. According to the information provided here, we can tell that
black figures represent h0m0zyg0us d0minant individuals, grey figures represent heter0zyg0us individualsempty figures represent h0m0zyg0us recessive individualsRemember that Generations are represented with roman numbers.
We will name the plants with numbers from 1 to 26.
According to the information in the statement and the information in the pedigree, we can say that grey individuals from the fourth generation are heter0zyg0us expressing round seeds. They can produce wrinkle seeds, if they are fertilized by another heter0zyg0us plant or a h0m0zygous recessive one.
Option 1:
Two heter0zyg0us plants are crossed, and their offspring have wrinkled seeds.
Option 2:
One heter0zyg0us plant is crossed with a h0m0zyg0us recessive one, and their offspring have wrinkled seeds. Let us see the cross

Select all that apply.
Animals cannot consent to being used in experiments.
Animals are ideal biological models for experiments
Many animals can be studied at one time.
Some animals may have adverse reactions.
Answer: Animals cannot consent to being used in experiments.
Explanation:
Animals are not suitable options for the biological research as they are getting extinct and their population size is getting decreased. Option A is correct.
What are extinct species ?These are the species that are getting diminished from planet because of certain factors such as loss of habitat and many other crucial factors that affecting their growth.
Animals can not be used in the biological research as they are not able to speak the language which is understood by humans and ideally it is not right to do dissection over living beings.
Animals earlier were definitely considered for the experiment but the awareness of ethics and sensitivity of the issues is bringing down the ban on the animal crimes along with the lab research.
Ethical concerns are as well that without God's permission it is not right to harm the living beings.
