Qué factores interviene en la manifestación de los genes? (pregunta de indagación)
Toma en cuenta el concepto de gen: El gen es la unidad física básica de la herencia. Los genes se transmiten de los padres a la descendencia y contienen la información necesaria para precisar sus rasgos. Es la unidad molecular de la herencia genética, pues almacena la información genética y permite transmitirla a la descendencia.
Ahora, planteamos nuestra HIPÓTESIS o respuesta probable a nuestra pregunta de indagación. Recordemos que tiene que tener las dos variables en relación de causa – efecto.
VARIABLE INDEPENDIENTE (CAUSA) VARIABLE DEPENDIENTE (EFECTO) INTERVINIENTES
En este caso, la hipótesis podría ser: los genes se manifiestan de acuerdo a mecanismos genéticos y ambientales. En este caso, las variables independientes (causas) podrían estar representadas por interacciones génicas e intergénicas tales como relación de dominancia completa o epistasis (factores genéticos) o bien cambios de temperatura (factores ambientales), los cuales inciden sobre la variable dependiente (grado de expresión génica) y cuyos efectos están representado por el fenotipo del individuo.
La hipótesis es una explicación plausible a un fenómeno observado en el mundo natural, la cual puede ser comprobada (o rechazada) mediante el uso del método científico.La variable independiente o 'causa' puede ser definida como la variable que produce un efecto sobre la variable dependiente, y que no cambia a lo largo del experimento.Por otra parte, una variable dependiente es una variable que cambia a lo largo del experimento de acuerdo a la variable independiente y que el investigador mide para determinar el efecto de la variable independiente.Aprende más sobre este tema en:

Explanation:
Ashley hypothesizes that adding coffee grounds to the soil will help the plants grow faster. She designs a controlled experiment to determine if this hypothesis is supported.She grows one group of soybean seedlings under normal conditions. She mixes three tablespoons of coffee grounds into the soil of the second group and grows the seedlings under the same light, temperature, and watering regimen. After three weeks, she measures the height of the seedlings and compares the two groups.Identify the parts of the experiment. Place only one term in each category. You will not place all the terms.
The purpose of this study is to determine the experimental group, the control group, the dependent variable, and the independent variable.
Designing and carrying out an experiment is the best approach to prove whether a hypothesis is true or incorrect. To ensure that an experiment examines exactly what the hypothesis claims, scientists must be cautious in how they construct it.
To ensure that only one factor is being altered in an experiment, the independent variables are therefore divided into two groups.
The control groupThe experimental groupThe control group does not experience any changing variable.
The experimental group receives all of the experiment's circumstances, changes as well as the one variable that the experiment is testing.
In Ashley's experiment:
The experimental group:
Seedlings grown with coffee grounds.The control group:
Seedlings grown without coffee grounds.The dependent variable:
Seedling heightThe independent variable:
SoilTherefore, we can conclude that we understand the concept of the experiment carried out by Ashley.

The purpose of an experiment is to gather data to determine if the Is supported or not supported
Answer:
hypothesis
Explanation:
the reason you do the experiment is to test the hypothesis
The purpose of an experiment is to systematically gather data and information through controlled procedures in order to investigate a hypothesis or research question. The goal is to determine whether the hypothesis is supported by the collected evidence or not.
Here's a breakdown of the process:
1. **Hypothesis:** An experiment starts with a clear hypothesis or research question. This is a statement that suggests a relationship or an effect between variables.
2. **Design:** The experiment is designed with careful consideration of variables, controls, and methods. Variables are factors that can change or influence the outcome. Controls are used to minimize the impact of extraneous variables that could affect the results.
3. **Data Collection:** During the experiment, data is collected by making observations, measurements, or recordings of relevant variables. This data is collected according to the experimental design.
4. **Analysis:** Once the data is collected, it is analyzed using statistical or other relevant methods. The analysis aims to uncover patterns, relationships, and trends in the data.
5. **Interpretation:** Based on the analysis, researchers interpret the results to determine whether the collected data supports or contradicts the initial hypothesis. The interpretation should be objective and based on evidence.
6. **Conclusion:** The conclusion drawn from the experiment is either that the hypothesis is supported (the data aligns with the predicted outcome) or not supported (the data does not align with the predicted outcome).
7. **Implications:** If the hypothesis is supported, it can lead to further understanding, validation, or application of a concept. If the hypothesis is not supported, it could suggest a need for revising the hypothesis, altering the experimental design, or exploring different avenues of research.
It's important to note that a single experiment might not definitively prove or disprove a hypothesis. Replication of the experiment by other researchers and conducting further studies can provide more robust and reliable conclusions. In summary, the purpose of an experiment is to generate data that enables researchers to draw conclusions about whether a hypothesis is supported or not supported by the observed evidence.

• An earthworm is a terrestrial invertebrate that belongs to the phylum Annelida. They exhibit a tube-within-a-tube body plan, are externally segmented with corresponding internal segmentation, and usually have setae on all segments.
• They occur worldwide where soil, water, and temperature allow. Earthworms are commonly found in soil, eating a wide variety of organic matter.
• This organic matter includes plant matter, living protozoa, rotifers, nematodes, bacteria, fungi, and other microorganisms. An earthworm's digestive system runs the length of its body.
• It respires through its skin. It has a double transport system made of coelomic fluid that moves within the fluid-filled coelom and a simple, closed circulatory system. It has a central and peripheral nervous system.

The insect that is the strongest singer in the animal kingdom
Answer:
hope this helps
Explanation:
Dr Fernando Montealegre-Z, from the School of Life Sciences, University of Lincoln, UK, said: "To call distant females, male katydids produce songs by 'stridulation' where one wing (the scraper) rubs against a row of 'teeth' on the other wing. The scraper is next to a vibrating drum that acts like a speaker. The forewings and drums are unusually reduced in size in the Supersonus species, yet they still manage to be highly ultrasonic and very loud."
The insect that is considered the strongest singer in the animal kingdom is actually the male cicada. Male cicadas produce loud and distinctive mating calls using specialized sound-producing organs called "tymbals" located on their abdomen.
Cicadas are known for their loud and persistent buzzing or chirping noises, which can reach up to 120 decibels. This is comparable to the noise level of a rock concert or a chainsaw. The high-pitched mating calls of some species of cicadas can be heard from great distances and are often described as a chorus. However, among insects, cicadas are certainly among the most notable for their impressive vocalizations.

drag the label to the appropriate locations in this concept map protein
Proteins are sequences of amino acids joined by peptidic bonds. These sequences determine their function in cells. They characterize for expressing primary, secondary, tertiary, and quaternary structure.
-----------------------------------------------------------------
Amino acids are organic molecules. They are composed of a central carbon, one hydrogen atom, one carboxyl group, one amine group, and one R group. The composition of the R group is what makes them different from each other.
Proteins are amino acid polymers linearly arranged and connected by peptidic bonds. These molecules characterize by their different structures.
The primary structure refers to the sequence in which the amino acids are arranged in the chain. The secondary structure is the folding that the polypeptide chain adopts through the hydrogen bonds between the atoms.The hydrogen bonds are set between the -CO- and -NH- groups of the peptide bond (the first as an H acceptor and the second as an H donor). These conformations with less free energy, and therefore, more stable. The most common secondary structures are alpha-helix and beta-sheet.
Many proteins can express both secondary structures, alpha-helix, and beta-sheet.
Proteins acquire a tertiary structure that makes them more stable. Lineal polypeptides get folded and turn into a shape that makes them more stable in the environment and capable of accomplishing their biological role. The hydrophilic R-groups stick in the center of the polypeptide, facing the protein interior, and avoiding interaction with water. When proteins are composed of more than one polypeptide subunit, they arrange in a fourth structure, named quaternary structure.The many functions that proteins accomplish depend on the aminoacids sequences.
So, the appropriate locations in this concept map are as follow,
a) amino acids
b) functions
c) peptide bonds
d) central carbon
e) primary structure
f) secondary structure
g) R-group
h) tertiary structure
i) quaternary structure
