Explanation:
Si una planta homocigótica de tallo alto (AA) se cruza con una homocigótica de tallo enano (aa), sabiendo que el tallo alto es dominante sobre el tallo enano, ¿Cómo serán los genotipos y fenotipos de la F1?
Answer:
Genotipo: 4/4 o 100% de la progenie será Heterocigota para la característica altura del tallo, Aa.Fenotipo: 4/4 o 100% de la progenie expresará tallos altos.Explanation:
Datos disponibles:
Característica: Altura del talloAlelo dominante, A, expresa tallo alto en homocigosis (AA) y en heterocigosis (Aa).Alelo recesivo, a, expresa tallo enano en homocigosis (aa).Cruza: una planta homocigótica de tallo alto con una homocigótica de tallo enano (aa)
Parentales) AA x aa
Fenotipos) Tallo alto Tallo enano
Gametos) A A a a
Cuadro de Punnet) A A
a Aa Aa
a Aa Aa
F1) Genotipo: 4/4 o 100% de la progenie será Heterocigota para la característica altura del tallo, Aa.
Fenotipo: 4/4 o 100% de la progenie expresará tallos altos.
Nota: Por conocimiento teórico, es posible que no sea necesario el uso del cuadro de Punnet para realizar esta cruza. Esto es porque sabiendo que uno de los parentales es homocigota dominante y el otro parental homocigota recesivo, con un solo gen dialélico involucrado en la cruza, indefectiblemente la progenie será heterocigota. Un parental solo puede ofrecer gametos dominantes para la característica mientras que el otro parental solo puede ofrecer gametos recesivos. Aún asi, el cuadro de Punnet siempre resulta útil para poder visualizar bien los cruzamientos, siempre que estos últmos involucren pocos genes.

Which would have most likely stopped Mendel from finding a pattern in his
results?
A. If having a wrinkled seed had been a recessive trait
B. If garden peas had used sperm and egg to reproduce
C. Being short is a recessive trait
D. If seed color and shape were located on the same chromosome
Answer:
D. If seed color and shape were located on the same chromosome
Explanation:
If seed color and shape were located on the same chromosome, they would not be inherited independently of one another.
Genes on the same chromosome are more likely to be inherited together. The only way they could be inherited independently is if crossing over occurred between the two genes.
Therefore, this would argue against Mendel's law of independent assortment.

How does the muscular system help humans maintain posture?
1.Muscles continually align themselves vertically to help maintain posture.
2.Muscles continually push bones to be straight.
3.Muscles constantly contract to help fight gravity.
4.Muscles constantly contract to help work with gravity.
Answer:
a
Explanation:
Muscles continually align themselves vertically to help maintain posture.
What is Muscular system?Muscle fibers are specialized cells that make up the muscular system. Their ability to contract is its main characteristic. Movement is caused by muscles that are connected to blood vessels, internal organs, or bones.
Muscle contraction is the primary cause of almost all bodily movement. Cilia, the flagellum on sperm cells, and certain white blood cell amoeboid movement are examples of exceptions to this rule.
Walking and running are two examples of visible movements that are produced by the coordinated action of joints, bones, and skeletal muscles. Skeletal muscles can also make softer motions that influence different facial expressions, eye movements, and breathing.
Therefore, Muscles continually align themselves vertically to help maintain posture.

In studying the environment, nature does the experiments, scientists collect the data. How does the principle of uniformitarianism help answer questions about environmental changes?
Answer:
The principle of uniformitarianism helps answer questions about environmental changes because it gives scientists the idea that the scientific conditions that exist today have always been in existence. This makes it easier to draw correlations.
Explanation:
The principle of uniformitarianism states that the natural conditions that exist today have remained unchanged through the span of human life. This helps scientists in their understanding of nature. For example, they are better able to understand the formation of the earth as well as the uniformity of law across space and time.
Uniformity of law is an aspect of the principle of uniformitarianism which states that the laws of nature are constant across time and space. Uniformity of degree states that geological conditions have remained constant over time. These principles help scientists to better understand environmental changes.

Which of the following statements describes one way that energy is transferred in a food web?
Plants provide energy to consumers.
Energy is cycled between producers.
Consumers obtain energy directly from sunlight.
Producers store energy made by animals.
Answer: energy is cycled between producers
Explanation:
Plants provide energy to consumers, herbivorous and decomposers consumers are the only two groups that directly receive energy from plants.
What is a food web?The process of photosynthesis in plants transforms solar energy, which makes up the vast majority of the energy in food webs, into chemical energy.
When molecules are broken down during respiration in plants, a small fraction of this chemical energy is converted directly into heat. From producers to consumers, energy flows.
The relationships between species in a biotic community that involves eating are described by food chains, food webs, and/or food networks. In other words, they demonstrate the flow of resources and energy within an ecosystem from one species to another.
Therefore, plants provide energy to consumers one way that energy is transferred in a food web, hence option A is correct.

This question is incomplete as it lacks a word bank, the word bank are:
Ions
Electrons
Isotopes
Molecules
Covalent
Negative
Ionic
Molecular
Hydrogen
Point
Element
Ionic compound
The answer is:
1. Ions
2. Ionic
3. Covalent
4. Molecule
Explanation:
An ION is a charged atom i.e. an atom with positive (+) or negative (-) charge, which results when an atom loses or gains electrons respectively. The ions of different elements are held together by bonds called IONIC BONDS, which are bonds that form as a result of the difference in electric charges or electrostatic forces between the atoms involved. For example, an ionic bond forms between NaCl because there is an electrostatic force between the positive Na+ ions and negative Cl- ions.
However, on the contrary, when electrons are shared between atoms, a COVALENT BOND is formed. The atoms share their valence electrons to form a MOLECULE, which comprises of two atoms.
What type of bonds attracts water molecules

-covalent bonds
-double bonds
-hydrogen bonds
-ionic bonds
Answer:
Hydrogen bonds
Explanation:
hydrogen bonds are slightly positive which is attracted to the slightly negative charge of oxygen.

Explanation:
Answer:
The electron transport chain can convert the energy from one glucose molecule's worth of FADH2 and NADH + H+ into as many as 34 ATP
Explanation:
The process of forming ATP from the electron transport chain is known as oxidative phosphorylation. Electrons carried by NADH + H+ and FADH2 are transferred to oxygen via a series of electron carriers, and ATPs are formed. Three ATPs are formed from each NADH + H+, and two ATPs are formed for each FADH2 in eukaryotes.
Rotenone, a piscicide (fish poison), interferes with the transfer of electrons between Complex I and Complex II in the process shown above. Which of the following results would be expected in the mitochondria of fish exposed to Rotenone? Why?
Answer:
Mitochondria stops working.
Explanation:
When the mitochondria of fish exposed to Rotenone, it inhibits the cellular respiration which is the main cause of death of fishes. This inhibiting of cellular respiration in mitochondria leads to reduction in cellular uptake of oxygen and this reduction is responsible for the death of fishes. This Rotenone releases by the plants present in the water as well as used as pesticides for killing of fishes.
