What was a conclusion that Mendel drew from the F2 generation of this cross?
A.
Three fourths of the F2 plants show the round seed phenotype and carry the dominant allele for roundness.
Answers
Answer:
option A
Explanation:
option A is the correct answer of this question .
plz mark my answer as brainlist plzzzz vote me also.
hope this will be helpful to you.
three fourth of f2 plant showed round seed phenotype and carry dominant allele for round ness character.
what is dominant character ?
allele can be defined as a form of a gene which can be present as a pair shows either homozygous or heterozygous phenotype of a character.
these gene can express the phenotype either dominant or recessive form. In a cross between two organism, in F2 generation the offspring's are produced shows three phenotypes homozygous dominant, recessive, heterozygous dominant.
dominant allele can suppress recessive allele.

How are enzymes important for biochemical reactions?Enzymes are often called a catalyst because they increase can the speed of a biochemical reaction. Scientists often measure how quickly biochemical reactions occur in cells. The time it takes for a biochemical reaction to start and finish is known as the reaction rate.
Enzymes share two key characteristics with all other catalysts. First, they speed up chemical processes without being eaten or irreversibly changed by the process. They also speed up reactions while maintaining the chemical equilibrium between reactants and products.
Therefore, the enzyme acts as a catalyst to speed up a biochemical reaction.

Answers
.
Explanation:
1)The cell membrane functions as a semi-permeable barrier, allowing a very few molecules across it while fencing the majority of organically produced chemicals inside the cell. Electron microscopic examinations of cell membranes have led to the development of the lipid bilayer model (also referred to as the fluid-mosaic model). The most common molecule in the model is the phospholipid, which has a polar (hydrophilic) head and two nonpolar (hydrophobic) tails.
2) simple diffusion across the cell plasma membrane. The structure of the lipid bilayer allows small, uncharged substances such as oxygen and carbon dioxide, and hydrophobic molecules such as lipids, to pass through the cell membrane, down the concentration gradient is , by simple diffusion.
3) some molecules, such as carbon dioxide and oxygen, can diffuse across the plasma membrane directly, but others need help to cross its hydrophobic or however, because they are charged the polar, they can't cross the phospholipid part of the membrane without help .
4) during fission a copy of the DNA is made and attached to the cell membrane as well.

what is the base-pair rule for a DNA strand matching an RNA strand?
Answers
Explanation:
The base pairing of guanine (G) and cytosine (C) is just the same in DNA and RNA. So in RNA the important base pairs are: adenine (A) pairs with uracil (U); Guanine G() pairs with cytosine (C).
The Chargaff rule only holds true for DNA. Base pairing doesn't take place since RNA is single-stranded. Consider a DNA strand.
What make base pair unique in DNA and RNA?Compare the two DNA strands' base-pair rules to this one. Since uracil is absent from DNA, T and A complement one another. In contrast, T bonds with A and A bonds with U in a DNA/RNA match.
Important: It serves as the foundation for base pairing. This rule can be used to both determine the DNA strand length and if a base is present in the molecule.
Adenine and thymine are always equal, and cytosine and guanine are also always equal, allowing us to calculate the percentages of each base.
It assists in figuring out the makeup and structure of DNA in various species. It is constant within a species.
Therefore, the base-pair rule for a DNA strand matching an RNA strand.

The energy that fuels food webs begins as light energy from the sun. True or False
Answers
Answer: i think its true. ( based of information i got)
Explanation: The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers such as plants, algae, and cyanobacteria use the energy from sunlight to make organic matter from carbon dioxide and water. This establishes the beginning of energy flow through almost all food webs. also A food web consists of many food chains. A food chain only follows just one path as animals find food. eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. A food web shows the many different paths plants and animals are connected.

K. The pressure inside the container was measured to be 2.7 atm. What was the initial
temperature of the gas (in Kelvin)? Round answers to the ones place.
Answers
Answer:
Final temperature, T2 = 2460 Kelvin.
Explanation:
Given the following data;
Initial pressure = 1atm
Final pressure = 2.7atm
Initial temperature = 911K
To find the final temperature, we would use Gay Lussac's law;
Gay Lussac law states that when the volume of an ideal gas is kept constant, the pressure of the gas is directly proportional to the absolute temperature of the gas.
Mathematically, Gay Lussac's law is given by;
[tex] PT = K[/tex]
[tex] \frac{P1}{T1} = \frac{P_{2}}{T_{2}}[/tex]
Making T2 as the subject formula, we have;
[tex] T_{2}= \frac{P_{2}}{P_{1}} * T_{1}[/tex]
Substituting into the equation, we have;
[tex] T_{2}= \frac{2.7}{1} * 911[/tex]
[tex] T_{2}= 2.7 * 911 [/tex]
Final temperature, T2 = 2459.7 ≈ 2460 Kelvin.

molecule and another atom, such as oxygen, with a partial negative charge on an adjacent molecule.
Answers
Answer:
Due to difference in the values of electronegativities.
Explanation:
A covalent bond is formed between hydrogen atom with a partial positive charge on it and another atom, such as oxygen, have a partial negative charge on an adjacent molecule. This is because of the difference in the values of electronegativities. The hydrogen atom has lower electronegativity value as compared to oxygen so the shared pair of electron is slightly attracted by oxygen atom towards itself and formed partial positive charge on hydrogen and partial negative charge on oxygen atom.

B.A decrease in necessary resources.
C.An expansion of suitable living space.
D.A series of severe weather events in the habitat.
Answers
Answer:
a series of severe weather events in the habitat
An increase in the population of an organism would most likely be associated with a series of severe weather events in the habitat. The correct option is D.
What is the population?A collection of creatures from the same species that can interact to create fertile progeny. It is on a level above organisms but below the ecosystem and community.
An ecosystem is a level of organization where several communities of various species and the associated abiotic elements interact. It is the place where different population interacts with each other.
A biosphere and a biome are larger organizational levels than this one. Communities are levels of the organization where various populations coexist and engage in social interactions.
Therefore, the correct option is D. A series of severe weather events in the habitat.
