The mass of a cylinder of beetroot was 2.5 g. If its final
mass was 2.7 g, what was the
increase in mass in per cent?
Answer: The percent increase in the mass of cylinder of beetroot is 8%.
Explanation:
To calculate the percent increase in the mass of cylinder, we use the equation:
[tex]\%\text{ increase in mass}=\frac{\text{Final mass - Initial mass}}{\text{Initial mass}}\times 100[/tex]
We are given:
Final mass of the cylinder = 2.7 g
Initial mass of the cylinder = 2.5 g
Putting values in above equation, we get:
[tex]\%\text{ increase in mass}=\frac{2.7-2.5}{2.5}\times 100\\\\\%\text{ increase in mass}=8\%[/tex]
Hence, the percent increase in the mass of cylinder of beetroot is 8%.

Answer:A adenine could hydrogen-bond with thymine and guanine could hydrogen bond with cytosine to hold the helix together
Explanation:
The double helix model of DNA explained Chargaff's rules because adenine could hydrogen-bond with thymine and guanine could hydrogen-bond with cytosine to hold the helix together. The correct option is A.
What is Chargaff's rule?According to Chargaff's criteria, guanine and cytosine should be equal in amount in the DNA of every species and organism, and adenine and thymine should be equal in amount.
Additionally, the purine and pyrimidine bases should be in a 1:1 stoichiometric ratio.
The ratio of the several nitrogenous bases present inside the DNA molecule is described. It assists in figuring out the makeup and structure of DNA in various species.
Because adenine could hydrogen bond with thymine and guanine could hydrogen bond with cytosine to maintain the helix together, the double helix model of DNA provided an explanation for Chargaff's rules.
Thus, the correct option is A.

Which is a characteristic of diatoms?
Diatoms have two distinct shapes: a few (centric diatoms) are radially symmetric, while most (pennate diatoms) are broadly bilaterally symmetric.
What are Diatoms?Any member of the vast group of several genera of microalgae that can be found in the world's oceans, streams, and soils is referred to as a diatom.
Diatoms can photosynthesize, which allows them to change the dissolved carbon dioxide in the water into oxygen.
For higher-ranking organisms in the food chain, like invertebrates and tiny fish, they serve as a major source of food. In the energy and nutrition cycles of water resources, diatoms can also be vital players.
Diatoms can be divided into two shapes: pennate diatoms, which make up the majority, are broadly bilaterally symmetric, and central diatoms, which make up the minority.
Thus, these are the characteristics of diatoms.

Examine equations A and B below. Then answer the questions.
(A) 2H2 + O2 ® 2H2O (B) H2CO3 - H + HCO3
20. Which equation represents the formation of water?
21. Which equation represents the formation of an acid solution?
22. How many atoms of oxygen (O) are on both sides of equation
23. How many atoms of hydrogen (H) are on both sides of equation
24. How many atoms of hydrogen (H) are on both sides of equation
25. In which equation are carbonic acid molecules broken apart into
hydrogen ions and bicarbonate ions?
Answer: 20. A 21. B 22. A=2, B=3 23. A=4, B=3 25. B
Explanation: A has H2O (water). B has a hydrogen ion, so acidic.
In B H2CO3 is carbonic acid
The loss of hydrogen atoms leads to the formation of acids and the hydroxide forms bases. Equation A represents the formation of water, and equation B shows the acidic solution.
What is a chemical reaction?Chemical reactions are said to be involved in producing products from the reactants that undergo chemical changes. Water is formed by reacting the four hydrogens and one oxygen molecule as:
2H₂ + O₂ → 2H₂O
Equation B represents the formation of the acid as hydrogen ions are released along the product. The proton donation (hydrogen ion) is the characteristic property of the acids.There are 2 oxygen atoms in equation A, and 3 atoms of oxygen in equation B.There are 4 hydrogen atoms in equation A and 2 atoms of hydrogen in equation B.In equation B, carbonic acid breaks to form hydrogen ions and bicarbonate ions as:H₂CO₃ → H⁺ + HCO₃
Here, carbonic acid dissociates a proton that makes the solution acidic.
Therefore, the first equation represents the formation of water by oxygen and hydrogen atoms.

1.How does Nitrogen cycle through the enviroment?
2. Trace the steps that carbon cycles from plants,animal,and enviorment?
Answer: 1. The nitrogen cycle is a biogeochemical cycle.
2. The carbon cycle is a biogeochemical cycle.
Explanation:
1. The nitrogen cycle can be defined as the biogeochemical cycle in which the atmospheric nitrogen is utilized by the plants which is fixed by the soil bacteria. The nitrogen becomes the part of the biosphere as plants utilize it as an important development mineral. The nitrogen cycle involves the nitrogen fixation in which plants fix nitrogen by the help of bacteria into ammonia, nitrification in which the ammonia is converted into nitrite, nitrogen assimilation in which the plants assimilate and utilize the nitrogen for their growth and development, and denitrification involves the reduction of nitrite into atmospheric nitrogen. The conversion of nitrogen is carried out via physical and biological processes.
2. The carbon cycle involves the atmospheric carbon dioxide being circulated in plants as they utilize it for photosynthesis. The carbon dioxide is fixed by the plants in the form of carbohydrate which is consumed by the animals and on decomposition of plants and animals dead matter release carbon dioxide gas to the atmosphere. This allows the recycling of the carbon dioxide gas in the environment.

Feeding problems may develop during the preschool years partially because of:_______
a. decreased appetite associated with decreased growth rate.
b. increased appetite associated with increased growth rate.
c. increased metabolic rate.
d. increased need for finger foods.
Answer:
The correct option is A.
decreased appetite associated with decreased growth rate
Explanation:
Feeding problems may develop in preschool age because of decreased appetite associated with decreased growth rate and this is because at the preschool age, there is no rapid growth, the growth rate is reduced which is as a result of decreased appetite for food. We all know that food supply the body with energy and necessary nutrients for growth. When there is decreased appetite enough food needed for growth will not be consumed , hence decrease growth rate.
