Plants take the CO2 from the atmosphere which is used in Calvin's cycle to synthesize organic compounds that end up building the plant. This fact can be proved by marking the atmospheric CO2 with radioactive isotopes of carbon, afterwards using a Geiger counter the plant will present radioactivity.

The carbon in the atmosphere is most commonly found in the form of CO2

it has a concentration of 0.04%.CO2 is a byproduct of aerobic respiration

or combustion, for example, C6H12O6+6O2-->6CO2+6H2O. The CO2 is then used by plants in photosynthesis as mentioned earlier.

Carbon is present in the biosphere because all life is made of carbon.

Carbon is present in the geosphere most commonly under the form of hydrocarbons like methane(CH4). The carbon present in geosphere is a result of organisms decay and metabolic byproducts. For example, methanogen bacteria synthesize methane in anaerobic conditions reducing hydrogen in the presence of CO2(CO2+4H2⇒CH4+2H2O). Carbon in the geosphere can also be found in coal that becomes diamond under extreme pressure and temperature.

Carbon element exists in various parts of the atmosphere in the form of gases such as carbon dioxide. The growth of land plants proof that there is carbon in the atmosphere as they perform photosynthesis.

The atmospheric carbon refers to the carbon dioxide which is present in the atmosphere. The main source of this carbon dioxide is respiration in animals.

There is an exchange of carbon from the atmosphere, vegetation, soils and the organic matter of the atmosphere, ocean and fossil fuels all of these are continually changing. The carbon cycle is the cycle through which carbon is exchanged among the various parts of the globe that is the biosphere, geosphere, and atmosphere of the Earth.

The growth of land plants is a proof that there is carbon present in the atmosphere because the land plants use carbon dioxide and water to grow. Carbon dioxide and water are both the gases and important part of the atmosphere, so when they are combined they usually form a liquid. This liquid is then absorbed by the plants and they use it to make their own food through photosynthesis.

First, it is necessary that this scientist decide on what point of the Cretaceous period he wants to study. Among several points he may want to study the evolution of microorganisms of that time, the life of a dinosaur species, or the evolution of dinosaurs, the flora that was established during this period, among others. This is the phase of the scientific method called Observation.

After that, he must enter the phase called "Elaboration of hypotheses" where he will raise questions about the point he decided to study. "How many flower species existed in that period?", "How many of these flowers can we observe today?" among others.

After that, he will enter the phase called "Experimentation", where he will establish a type of experiment and all the experimental factors and variables that will allow the hypotheses to be answered.

After the experiment he will collect the data that will be analyzed and that will give results that will answer the hypotheses previously established. This is the phase called "Analysis of the results".

At that moment, he will be able to reach the last phase of the scientific method, the phase called "conclusion", where he will show the conclusions that the experiment allowed to be established.

The Cretaceous period was a prehistoric period that took place between about 140 and 60 million years ago. If a scientist wanted to use the scientific method to learn more about this time, he should implement the following steps:

Answer:

Este es un ejemplo de dominancia incompleta. Es una ocurrencia genética que ocurre cuando un gen dominante no expresa su manifestación completa en el alelo recesivo en un alelo dominante heterocigoto.

Por lo tanto, ambos rasgos se manifiestan, lo que resulta en la combinación de los dos alelos para los colores (blanco y rojo). Se dice que el alelo rojo dominante exhibe un dominio parcial sobre el alelo blanco recesivo, y esto da como resultado el alelo completamente rosado.

De acuerdo con la ley mendeliana, las dos flores rojas son heterocigóticas. Por lo tanto, las flores rojas heterocigóticas dominantes deben ser R. El alelo blanco es recesivo (rr) enmascarado por el rojo R,

Sin embargo, cuando se cruzan los dos alelos heterocigotos rojos:

Los fenotipos están en forma de

RR, (1) rojo Rr Rr (2) rosa rr (1) Blanco.

Esto ocurre porque el alelo rojo dominante no era total / completamente dominante en el alelo recesivo blanco en cada uno, lo que da como resultado un alelo rosa (el tercer fenotipo)

This is an example of incomplete dominance.It is a genetic occurrence  which occurs when a dominant gene does not express it full manifestation on the recessive allele in an heterozygote dominant allele.

Therefore,both traits are manifested which results in the blend of the two allele for colors(white and red).The dominant red allele is said to exhibit partial dominance over the recessive white allele.And this results in the entirely pink allele.

Based on Mendelian law the  two red flowers are  heterozygotes .Therefore, Red heterozygote dominant flowers should beRr.The white allele is recessive(rr) masked by the R-red,

However,when the two red heterozygote alleles are crossed:

The phenotypes are in the form of  

RR,(1) red  Rr Rr(2) pink  rr(1)White.

This occurs because, the dominant red allele was not fully/completely  dominant on the  white recessive allele in each,which results in pink allele(The third phenotype)

Explanation:

The branch of science which deals with living beings is called biology.

The language of the question is different so it is difficult to answer it.

According to the data given in the question, they are discussing incomplete dominance because the ratio is 1:2:1.

The cross in which the dominant parent is not able to show its character and does not able to suppress the recessive gene. In this case, the plants show the character of somewhere in between both of the cases.

Therefore, they get the ratio of 1:2:1 which indicates the phenotype of red: pink: white.

Hence, the correct answer is incomplete dominance.

Neglecting the child

Explanation:

Maldatives behaviors are the behaviors that do not facilitate the parent-infant bonding, meaning that they are those behaviors that are hindering the process. And the best way of removing that is to encourage the behaviors that counter them.

The process of pointing out the responsiveness of the infant is a positive strategy for facilitating parent-infant attachment. Telling the mother that she must pay attention to her infant may be perceived as derogatory and is not

appropriate. Educating the mother in infant care is important; however, pointing out the responsiveness

of her baby is a better tool for facilitating mother-infant attachment. .

Answer:

The Hardy-Weinberg equation can be used to gather valuable information about a population in the following two ways:

1) Estimating allele frequencies: The Hardy-Weinberg equation allows scientists to estimate the frequency of specific alleles within a population. By comparing the observed frequencies with those predicted by the equation, researchers can determine if the population is in genetic equilibrium, meaning that the allele frequencies are stable and not evolving over time.

2) Identifying evolutionary forces: If a population deviates from the expected Hardy-Weinberg equilibrium, it suggests that one or more evolutionary forces, such as natural selection, genetic drift, gene flow, or mutation, are at play. By analyzing these deviations, scientists can gain insights into the factors influencing the genetic makeup of the population and better understand the evolutionary processes driving changes in the population's gene pool.

Answer:

The minerals will not be move or transported to other part of the plants because active transport require energy.

Explanation:

Active transport is a process where molecules and ions are move against a concentration gradient by using energy.

This process require energy, for ions or molecules of minerals to be taken up by plants, it is first moved to the root hairs where they are in high concentration against in dilute concentration on soil Active Transport then occur in the roots where it is taken up to the plants with the use of energy.

If there is not enough energy, active transport will not occur and the minerals will remain in the root hair and will not be move to other part of the plant.
