Electron microscopy has enabled the greatest advances in understanding law of inheritance. Thus, option D is correct.
Inheritance can be defined as the process by which an offspring can carry genetic information from their parent.
Gregor Mendel who first postulated laws of inheritance while doing hybridization experiment on garden pea plant.
He proposed three laws
First Law of Dominance states that In an organism, a character express in two forms or allele.
In F1-progeny the allele which is expressed is called dominant, while the other remain masked is called recessive allele.
Second Law of segregation which states the alleles do not show any mixing and both the traits are appeared in F2-generation.
Third Law of Independent Assortment states that when two pairs of characters are combined, separation of one pair of trait is independent of other pair segregation of one pair of character.
Thus, option D is correct.

Answer:
DNA Analysis
Explanation:
Mold is a biotic component of the environment. It's a living organism that contributes significantly to the decomposition of dead matter. While molds are influenced by abiotic factors such as sunlight and salinity, they are themselves living and thus part of the biotic factors.
Mold is a biotic component, which means it's a living part of the environment. It consists of multicellular organisms that play critical roles in the decomposition of dead plants and animals. While they can be found in various environments, molds are categorized by their ability to grow as long filaments that form visible colonies.
Molds are critical to the life cycle and energy exchange in many ecosystems, contributing to critical biological processes. Abiotic factors, such as salinity and sunlight, influence the distribution and prevalence of molds in various ecosystems, but these are non-living components of the environment.
Simply put, molds are important organisms that contribute to the decomposition process and are considered part of the biotic factors in an environment due to their living nature, unlike abiotic factors such as water, air, soil, sunlight, and salinity.

Answer:
C. 10 inches per day
Explanation:
Kelp plants start by growing underwater then expand to the surface to obtain sunlight and continue expanding.
b. includes nucleic acids.
c. could only be made of triglycerides.
d. could only be made of carbohydrates.
e. does not include proteins or nucleic acids.
Answer:
d
Explanation:
The correct answer would be that the food could only be made of carbohydrates.
Proteins contain other elements such as nitrogen and sulfur in addition to carbon, hydrogen, and oxygen while nucleic acids and triglycerides contain phosphorus in addition to carbon, hydrogen, and oxygen.
The only chemical substance that contains carbon, oxygen and hydrogen is carbohydrates.
Correct option: d
The 'wonder food' contains only carbon, hydrogen, and oxygen, so it could only be made of carbohydrates. The correct answer is option d.
Based on the information given that the 'wonder food' contains only carbon (C), oxygen (O), and hydrogen (H), the most probably statement would be that 'it could only be made of carbohydrates'.
Carbohydrates are biologically important molecules composed of these three elements. They provide energy for the body and are crucial in numerous biological processes.
However, whereas proteins contain nitrogen and nucleic acids which have both nitrogen and phosphorus, this 'wonder food' does not appear to contain those elements, which rules out the presence of proteins and nucleic acids.
That said, without more specific information, it's also possible that it could contain triglycerides or other compounds like fats or oils, which also contain carbon, oxygen, and hydrogen. So while it's not certain, the best answer probably is 'it could only be made of carbohydrates' (option d).

O 1.2kg
120kg
Answer:
Explanation:
The amount of protein a lion gets from 2kg of beef depends on the protein content of the beef. The protein content of beef can vary, but on average, it is around 20%. To calculate the amount of protein in 2kg of beef, you can multiply the weight of the beef by the protein content:
2kg of beef x 20% protein = 0.4kg of protein
So, the lion would be getting 0.4kg of protein from 2kg of beef.
Remember, the protein content can vary, so it's important to check the specific protein content of the beef you are considering.
