In the process of photosynthesis, the light-dependent reactions produce energy-storing compounds that are used during the dark reactions. What are these energy-storing compounds? I NEED HELP QUICKKKKKK
The energy-storing products of the light-dependent reactions of photosynthesis are ATP and NADPH.
What is Photosynthesis?Photosynthesis may be defined as a process through which green plants and other photosynthetic algae synthesize their own food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.
The light-dependent reaction of photosynthesis occurs in the presence of light. It runs in the thylakoid membrane of the chloroplast. This type of reaction involves the flow of electrons. The final products of this reaction are ATP and NADPH which serve as the energy-storing compounds.
Therefore, the energy-storing products of the light-dependent reactions of photosynthesis are ATP and NADPH.

If both parents are black, which is a recessive trait, their offspring will be black. All of the 100% offspring will be black in nature, having the ff genotype. option 5 saying 100% is true for this.
How are the traits inherited?The traits are passed on from the parents to the offspring by sexual reproduction, which happens during the meiosis process. In the fur color of the dog, the dominant allele is F, which codes for the grey color, and the recessive allele is f, which codes for the black color.
The FF will show gray and the Ff will produce gray too, as the F is dominant over the f. Because it is recessive, the ff will have black fur.The cross of two purebred dominant (FF) parents will always form purebred gray offspring, and the heterozygous Ff parents will produce all types, such as grey and black offspring. The punnett square is explained below in the image.
As a result, all of the puppies will be black (ff) and 100% black.

Earth's oceans are salty as a result of water being able to dissolve minerals. When water dissolves a substance, weak charges on water molecules attract oppositely charged portions of the substance, pulling them out into solution. Which property of water accounts for this occurrence?
Answer:
b
Explanation:
The answer to it is called as solubility which accounts for the property where the salt gets dissolved in water. The salts get dissolved in water such that the water is having a property to solubilise the salts in it.
What is a type of solvent is water like ?It is the type of polar solvent which is hydrogen ion that is positive in nature with the hydroxide ion which is negative in charge.
Water molecules just pulls sodium and the chloride ions that are just apart which are just breaking the ionic bond that are holding them just together. After salt compounds which are just pulled apart from each other , sodium and chloride atoms are although surrounded by the water molecules . Once this happens then salt is just dissolved which is just resulting in the homogeneous solution.
Water dissolves the salt because positive part of the water molecules attracts negative chloride ions and negative part of the water molecules attracts the positive part that is the sodium ions. The amount of the substance which can dissolve itself in liquid at the particular type of temperature which is called as solubility of substance.

Cancer is a disease related to the cell life span and cell division. If cancer cells were added to the data table, predict what would be written under the columns headed “Life Span” and “Cell Division.” Explain the reasoning underlying your predictions.
Many people live much longer than 5 years after their cancer diagnosis. The term does not mean a person will only survive for 5 years.
For example, 90% of people with breast cancer will be alive 5 years after the diagnosis of cancer.
Cell Division:Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.
Cancer is a disease caused when cells divide uncontrollably and spread into surrounding tissues.

Puromycin is an antibiotic. Its effect is to force the ribosome to detach from the mRNA chain before reaching the stop codon. Explain why this would have a harmful effect on a bacterium.
Answer:
Please find the explanation below
Explanation:
Transcription and translation are the two proocesess involved in gene expression. These two processes are important because the end result is a PROTEIN responsible for the phenotypic characteristics of that organism. Transcription involves synthesis of mRNA from DNA while translation involves synthesis of protein from mRNA.
In this question, an antibiotics called Puromycin forces the ribosome to detach from the mRNA chain before reaching the stop codon. This means that the antibiotics "Puromycin" abruptly truncates the translation process. Hence, proteins will not be produced. This means that the organism (bacteria) will not be functionally active because of lack of necessary PROTEINS.

Explanation:
Brown hair is dominant over light colored hair. Cross two light haired people.
Answer:
All of the offspring will inherit light hair.
Explanation:
This is due to there being no presence of the dominant brown hair genes.
When a monohybrid cross is made between two parents which are homozygous light haired then all of the offspring in the F1 generation will inherit light hair color.
What is Monohybrid cross?A monohybrid cross is the cross of two pure line individuals with homozygous genotypes which result in the occurrence of opposite phenotype for a certain genetic trait. The monohybrid cross between two corresponding traits such as TT and tt is called a Monohybrid Cross.
For the hair-color trait, the brown hair color (B) is dominant over white hair color (b). If a cross is made between a brown-haired individual and a light-haired individual then it turns out that brown hair is dominant and all the offspring will have brown hair. And, when two homozygous recessive light-colored parents (bb) are crossed then the filial 1 generation will have all the individuals with light- hair color as none of the parents carry the allele for brown hair color.
The punnett square for this cross is attached with it.

Throwing a silver dollar across a river may have been quite a feat for a young man, but there is one fact that proves this story wrong. Silver dollars didn’t exist when Washington was a boy. The legend appears to come from a story explained by his biographer (you’ll meet him in a minute). Washington grew up north of Fredericksburg, Virginia, on Ferry Farm. This is very close to the Rappahannock River. His biographer wrote that George and his friends would throw rocks across the river while waiting for the ferry. The Rappahannock was only about 300 feet wide during Washington’s time. Throwing a rock across it would have been easy.Washington grew up north of Fredericksburg, Virginia, on Ferry Farm.

Could someone help : how does the number of offspring that are produced by an individual typically compare with the fecundity of that individual? What factors create this (think of reproductive potential)
Answer:
The number of offspring produced is often related to the amount of parental care. Typically, the higher fecundity, the lower the amount of time parents devote to caring for the offspring.
The number of offspring that are produced by an individual typically varies with the fecundity, as the higher the fecundity, the lower the parental care per offspring, while a lower fecundity leads to more parental care.
What is parental care in the animal kingdom?Parental care refers to the behaviors of parents for the care of their offspring, and in the animal kingdom, parental care can take many forms, ranging from simple behaviors like providing food and shelter to more complex behaviors like teaching and training offspring and parental care is important for the survival and development of offspring, as it can improve an offspring's chances of survival by providing them with resources, protection, and guidance.
Hence, the number of offspring that are produced by an individual typically varies with the fecundity, as the higher the fecundity, the lower the parental care per offspring, while a lower fecundity leads to more parental care.
