The energy absorbed by chlorophyll is not directly used
The energy absorbed by a molecule of chlorophyll b is not used directly for photosynthesis, but is passed by a resonance transfer mechanism to a molecule of chlorophyll a. A similar transfer of energy takes place when a carotenoid molecule absorbs a quantum of radiation.
Why is it important for a cell to perform checks after DNA replication?
A.
If errors are not removed from areas with a gene, then the resulting proteins could be affected.
B.
If errors are not removed from areas with a gene, then the resulting lipids could be affected.
C.
Errors in DNA replication that occur in any cell type will be passed to the offspring.
D.
Errors in DNA replication that occur in any cell type will always result in death of the cell.
Answer:
A. If errors are not removed from areas with a gene, then the resulting proteins could be affected.
Explanation:
Since the genes in DNA contain instructions for the synthesis of proteins, any mistakes in areas of a gene will change how proteins are made.
It is important for cells to perform checks in order to catch these mistakes, because otherwise, RNA will be carrying the wrong instructions to create a protein.
Answer:
A.If errors are not removed from areas with a gene, then the resulting proteins could be affected.
Explanation:
concentration:
the amount of a substance within a _______ of another
substance
Answer:
Volume
Explanation:
In chemistry, the CONCENTRATION of a solution is the amount of a substance present within a volume of another substance. In other words, the concentration refers to the amount of a solute dissolved in a particular volume of a solvent to make a solution.
Concentration can be expressed in mass per volume i.e. g/cm³ or mol per volume i.e. mol/L or mol/dm³ etc. The amount of a substance is measured in Mass or mole, while the volume of a substance in Litres (L).

The diagram below shows the process of translation.
What is represented by the structure labeled 2?
Answer:
The structure labeled 2 is tRNA, transfer RNA.
Explanation:
In this given diagram, the translation process is explained. The tRNA is represented by the lebel 2. tRNA carries the amino acid that makes the polypeptide chain .
What is the translation process?Translation is a process by which a polypeptide chain is formed using enzymes, energy sources such as ATP/GTP, mRNA, tRNA, and amino acids. It is an active process, so energy is used. The DNA, which consists of genes, codes for some characters. These characters are expressed in the form of proteins by the translation process.
In the given diagram, the mRNA is read by ribosomes, and tRNA reads the codons of mRNA. The ribosome reads from the 5' to 3' end of mRNA and adds amino acids.
Ribosomes have three sites: the A (acceptor site), the P (peptide site), and the E (exit site). Amino acid with tRNA is called charged tRNA. The charged tRNA binds at the A site, peptide bonds form at the P site, and the tRNA exits at the E site. Level 2 represents these tRNAs without amino acids.
Hence, lebel 2 explains the tRNA .

Define "Fracking" and ways it can alter/upset the water cycle.
Answer:
Fracking can contaminate water supplies if it is not done properly, because the fracking fluid injected into rock to enable gas to be released often contains chemicals. If the borehole is not properly cased to stop leaks, the fracking water can escape into the aquifer

A calico cat shows both the traits for orange fur and black fur.
What kind of allele expression is this?
Codominance
Explanation: Becuase both of the traits are showing.
The allele expression in the case of a calico cat which shows both the trait for orange fur and black fur is Codominance.
Codominance is a hereditary model that states that in the heterozygous there is no recessive allele, but on the contrary, both alleles behave as dominant and both manifest themselves without mixing.
Codominance is an important aspect of the crossing process because the two allele genes are expressed, but not joined. An example of this is calico cats that have two X chromosomes in each of their cells.
In calico cats, the gene for the orange fur is located on the X chromosome and they have one allele for the black fur. The only way that both alleles occur together and combined with white is that there are two X chromosomes and these are codominant or these express at the same time.

which statement best explains why correct protein folding is critical in the transmembrane protein shown above?
Answer:
- Interactions of the hydrophobic and hydrophilic amino acids help to anchor the protein in the membrane.
Explanation:
The above statement correctly defines that it is significant to fold protein correctly in the transmembrane protein as displayed above because the 'interactivity along the hydrophilic and the hydrophobic amino acids assist in harboring the protein in the membrane.' These 3-dimensional structures have a specific biological significance and promote better functioning. The incorrect folding of protein may give rise to numerous diseases.
Interactions of the hydrophobic and hydrophilic amino acids help to anchor
the protein in the membrane is the statement that best explains why correct
protein folding is critical in the transmembrane protein.
Protein consists of amino acids in a 3 dimension form and its correct folding
aids its optimal functioning. In a protein structure, there are interactions of
the hydrophobic and hydrophilic amino acids which acts as a strong anchor.
The hydrophobic parts of amino acids help to interact with the long chains
of the fatty acids in lipid bilayer while the hydrophilic part of amino acids
assist to interact with water on the surface of the cell membrane.

Please find the answers in the appropriate blank spaces in the sentence in BOLD.
Explanation:
As a result of photosynthesis, PLANTS synthesize organic compounds tha they use as a source of ENERGY. Photosynthesis converts SOLAR energy into CHEMICAL energy. Inside a CHLOROPLAST, chlorophyll pigments absorb LIGHT energy. This energy is then transferred to two chemical compounds; ATP and NADPH. These compounds are made in a set of reaction known as the LIGHT-DEPENDENT REACTION. These compounds are then used to drive another set of reactions known as the LIGHT-INDEPENDENT REACTION or CALVIN CYCLE. This second set of reactions changes CO2 into organic compounds known as SUGARS/CARBOHYDRATES.
The OXYGEN that is produced in photosynthesis comes from water molecules that split by LIGHT energy. As a result of photosynthesis, CO2 and WATER are changed into GLUCOSE and OXYGEN. The products of photosynthesis are used in another process called CELLULAR RESPIRATION, while photosynthesis is carried out only by PLANTS/AUTOTROPHS, respiration is carried out by both PLANTS/AUTOTROPHS and ANIMALS/HETEROTROPHS.
According to the question the answer in the blank space are as follow:
1. Plants
2. Energy
3. Solar
4. Chemical
5. Chloroplast
6. Light
7. ATP
8. NADPH

10. LIGHT-INDEPENDENT REACTION
11. Calvin cycle
12. Carbon dioxide
13. carbohydrates
14. Oxygen

What is do you mean by the terms photosynthesis and respiration?
Photosynthesis is the procedure by which plants utilise sunlight, water, and carbon dioxide to produce oxygen and energy in the form of sugar.
Respiration is a procedure in living organisms, that produce energy, generally with the intake of oxygen and the release of carbon dioxide from the oxidation of complicated organic substances.

A veterinarian conducts a study of meiosis in dogs. She observes that during anaphase I, there are 39 pairs of chromosomes being pulled toward opposite ends of the cell. Which of the following statements is false? A. Crossing over has already taken place. B. The diploid number for dogs is 78. C. There will be 39 chromosomes in each dog gamete. D. Each gamete will have two alleles for each gene.
Answer:
D. Each gamete will have two alleles for each gene.
Explanation:
Gametes are haploid (n) reproductive cells. In animals, female gametes are known as egg cells, while male gametes are sperm cells. Each gamete (either female gamete or male gamete) contains a complete set of chromosomes which in turn have a complete set of gene variants (i.e., alleles). In consequence, for each gene, the dog's progeny will inherit one allele from the father and one complementary allele from the mother, thereby having a diploid (2n) number of homologous chromosomes.
Answer:
D
