Answer:
When two people heterozygous for the trait of a bent pinky finger have a child, the possible genotypes CC, Cc and cc -in a ratio of 1:2:1- being the phenotypes bent pinkies: straight pinkies in a ratio of 3:1.
Explanation:
Bent pinky finger is due to a condition called Camptodactyly, characterized by sustained bending of a finger due to a deformity in an interphalangeal joint. Pinky finger camptodactyly is a trait that is inherited in an autosomal dominant pattern.
With camptodactyly (bent pinky finger) C Without camptodacilia (straight pinky finger) cThe parental generation is made up of two heterozygous individuals with bent pinky fingers:
♂ Cc
♀ Cc
The offspring of this hybrid cross, according to Mendelian heritage, can be seen in this Punnett Square:
Alleles C c
C CC Cc
c Cc cc
According to this the offspring will have:
Genotypes:
CC: 25%
Cc: 50%.
cc: 25%
Phenotypes:
Bent pinky finger: 75%
Straight pinky finger: 25%

Red blood cells need iron. They store iron and typically contain more iron than the fluid around them does. Which
action would show the blood cells doing active transport?
O pushing iron out
O bringing iron in
O swelling
O shrinking
Answers
Answer:
pushing iron out
Explanation:
Excess iron will be push out of the cell to regulate the internal environment of cell, this active transport involve osmosis.
if this type of reaction occur in a plant cell, the plant cell will shrink which may/will leads to death of the plant.

In essence, DNA is a thin and very, very long organic molecule. It is a polymer, and each of the monomers that constitute it are called ______
Answers
Answer:
nucleotides
Explanation:
DNAs are long-chain, helical macromolecules that store genetic information They are made up of varying sequences of covalently bonded monomers called nucleotides. Four types of nucleotides make up the nucleic acid DNA, these include Adenine, Guanine, Cytosine and Thymine.
Unlike other macromolecules, these are typically not used as an energy source and only encode protein synthesis. They comprise a 5-Carbon deoxyribose sugar, one nitrogenous base (adenine, guanine thymine, and cytosine) and a phosphate group.
Nitrogenous bases encourage base-pair formation through hydrogen bonding. Adenine forms double bonds with thymine, while cytosine forms triple bonds with guanine.
Nucleotides in a row on mRNA determine a specific amino acid in the polypeptide
Answers
Answer:
This statement is true. Nucleotides in the mRNA strand determine a specific amino acid, and its position, in the polypeptide.
Explanation:
Messenger RNA (mRNA) contains the information it has received from the DNA transcription, arranged in a nucleotide sequence, necessary to perform protein synthesis.
The sequence of nitrogenous bases in the mRNA can be distributed in trios of bases, called triplets or codons. Each of the codons encodes an amino acid, the beginning of the synthesis of a polypeptide or the completion of such synthesis. The order in which the nucleotides are found also determines the order or sequence of amino acids in a polypeptide.
A researcher is investigating the of effects a chemical that makes thylakoid membranes permeable to hydrogen ions (H+). Which of the following is most likely direct effectof adding the chemical to plant cells?
Answers
Answer:
B. The chloroplasts will generate less ATP
Explanation:
Photosynthesis, occurs in the chloroplasts of plants. Solar energy is converted into chemical energy in the form of stable carbohydrates.
6 CO2 + 6 H2O + light → C6H12O6 + 6 O2
Carbon Dioxide + Water + Light Glucose + Oxygen
Chloroplasts, are small membrane-bound organelles of multi-folded membranes containing pigments, enzymes, and other molecules that facilitate the process. The thylakoid contains multiple folded membranes called granum stacked together. They contain light-absorbing pigments like chlorophyll.
Here, absorbed light is used in photolysis, to split water produce H+, O2 and high-energy electrons for the high-energy producing electron transport chain.
Protons are pumped into the stroma within granum, producing ATP. ∴ Without ATPase, less ATP is produced.
Chloroplasts are the membrane-bound organelles, which carry out the process of photosynthesis. The correct answer is:
Option B. The chloroplasts will generate less ATP.
Photosynthesis is the process of preparing the food in presence of sunlight. It occurs in the plant. The chloroplasts are the membrane-bound organelles, which consists of pigments, enzymes, and other molecules. The thylakoid membrane consist of stacked membranes, known as grana. The light-absorbing pigment, chlorophyll is found in grana.
The following points can be used to explain photosynthesis:
The absorbed light initiates photolysis, which is the breakdown of water molecule into hydrogen and oxygen. During photolysis, high-energy electrons are also released. These electrons are utilised in the electron transport chain to provide energy.Therefore, the permeability of the protons into the granum will yield ATP. The less ATP will be produced without ATPase.

how is atmospheric carbon in the form of CO2 converted into a molecule that is usable to all organisms?
Answers
Answer:
The carbon-dioxide exists in the atmosphere, and it is dissolved in the water.
Explanation:
With the process of photosynthesis, it becomes organic, and by breathing, the organic gas goes back to carbon-dioxide.
The assimilation of carbon is the process when the carbon-dioxide converts to organic carbon with the help of living organisms. This organic carbon is then used for energy.

Answers
Answer:
Option C
Explanation:
The answer to this question is option C or "the leaves." The major site of photosynthesis in a plant is where the chloroplasts are located because it contains chlorophyll which is where photosynthesis takes place, chloroplasts is in all the green parts of a plant stem, leaves, and even the branches but it takes place mainly in the leaves of a plant because there is more leaves then roots or branches.

Proteins are the building blocks of enzymes, and proteins are made up of amino acids that are linked together in one or more polypeptide chains. Therefore, option (D) is correct.
What are enzymes?Enzymes are proteins that aid in the acceleration of metabolic processes, also known as the chemical reactions that take place in our bodies. They are responsible for the creation of some chemicals while also decomposing others. Enzymes are present in everything that is alive. Enzymes are something that are produced by our bodies spontaneously.
Enzymes regulate most biochemical reactions in animals, plants, and microbes, thus there are many examples. Animal digestive enzymes are well-known. Gastric juices break down food with the enzyme pepsin. Salivary amylase turns starch into sugar, starting digestion.

Which part of photosynthesis is represented by the diagram to the right
Answers
Answer:
Light-dependent reactions
Explanation:
Photosynthesis occurs in two stages: light-dependent reactions and light independent-reactions. This last stage is often called Calvin cycle.
The diagram shows reactions occurred in the thylakoid membranes which are located inside the chloroplasts. Therefore, we can identify that these reactions are the light-dependent reactions. During this part of photosynthesis, the energy from the sunlight is absorbed by a pigment called chlorophyl (Chl). Then, it is sequentially coverted into chemical energy stored in the form of molecules: NADPH (nitotinamide adenine dinucleotide phosphate) and ATP (adenosine triphosphate).

water
ATP
Answers
Answer:
Oxygen
Explanation:
........... ......
Oxygen and glucose are the reactant in process of cellular respiration. ATP is the primary product of cellular respiration, and carbon dioxide and water are waste products. Thus, option A is correct.
What is the importance of cellular respiration?During the process of photosynthesis, which creates glucose from water and carbon dioxide, solar energy is transformed into chemical energy. The byproduct is the emission of oxygen.
In the process of breaking down glucose during cellular respiration, oxygen is consumed, which also produces heat and chemical energy.
The terminal electron acceptor in cellular metabolism is oxygen. H2O is produced when oxygen takes hydrogen ions and electrons.
After passing via ATP synthase, hydrogen ions from the intermembrane space move from the mitochondrial matrix to produce ATP.
Therefore, oxygen molecule is a reactant in cellular respiration.
