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.

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.

What two electron carrying particles ("batteries!") does the electron transport chain use to get the energy it needs to
make ATP?
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:
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.

7(c)(i). The diagram 7.2 shows the materials used by Claudia for preparing
tea. Claudia finds that the colour of the tea is light. Why? *
Answer: Because she used cold water
Explanation:
Tea leaves contain different flavors that dissolve in water to give it its distinct taste as well as its color. If water is hot, the flavors will dissolve quickly due to the fast movement of the heated water molecules.
If the water is cold however, as is the case in the above scenario, the flavors will take longer to dissolve in the water which means that the tea's color will not change drastically leading to a light tea.
. Which statement accurately describes the energy needs for photosynthesis and cellular respiration?
The concentration of a substance inside a cell is greater than outside the cell. What type of transport is needed to move molecules of the substance from outside the cell to inside?
Answer:
Osmosis
Explanation:
The type of transport needed to move molecules of the substance from outside the cell to inside is active transport.
What is active transport?Active transport is the movement of molecules against a gradient or other form of resistance, for example from a lower to higher charge area.
Cells use active transport to accumulate molecules such as glucose and amino acids.
A cell must use energy to move compounds against such a concentration or electrochemical gradient.
Active transport mechanisms do exactly that, expending energy more often in the form of ATP to maintain proper ion and molecule concentrations in living cells.
In the given scenario, the concentration of substance is more inside the cell than outside and the substance has to move from outside to inside the cell. This requires energy for processing.
Thus, the given scenario can be accomplished using active transport.

Which sequence best explains the relationship between DNA and protein structure and function?
DNA → gene → protein → trait
DNA → amino acid triplets → protein → trait
DNA base triplets → amino acid sequence → protein folding pattern → protein shape and function
DNA shape → amino acid sequence → protein shape and function
ty <33
Answer:
DNA base triplets → amino acid sequence → protein folding pattern → protein shape and function
Explanation:
From Google:
"The Rules of Protein Structure. The function of a protein is determined by its shape. The shape of a protein is determined by its primary structure (sequence of amino acids). The sequence of amino acids in a protein is determined by the sequence of nucleotides [base triplet] in the gene (DNA) encoding it."

What is an amniote, and which animals on this tree are amniotes?
Amniotes are these animals such as reptiles and birds whose embryos have a membrane that surrounds them, as a protection, called amnion.
What are amniotes?They are an extensive group of animals such as reptiles, birds or mammals that have amnions during their embryonic phase.
The amnion is a fetal membrane that lines the chorion and delimits the amniotic cavity, that is, it is an internal membrane or closed sac that surrounds and protects the embryo.
Therefore, we can conclude that amniotes are these animals such as reptiles and birds whose embryos have a membrane that surrounds them, as a protection, called amnion.

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.
When electrons transfer from one atom to another, both atoms become Choose... and they are held together by a(n) Choose... bond. When electrons are shared between atoms, a(n) Choose... bond forms between the atoms, and the joined atoms become a(n) Choose... .
Answer:
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.

Answer:
plant cells
Explanation:
Rosa could be looking at plant cells.
Plant cells are generally joined together when tissues of plants are viewed under the microscope and each cell is usually with a cell wall. Animal cells, on the other hand, do not have cell walls.
Tissues are generally composed of similar cells that have been aggregated together to perform a function in the body of organisms. Both plant and animal tissues consist of many cells but only plant cells have cell walls.
