If a population's per capita growth rate is 0.02 and its population is 100000000, the size of the population after 5 years is equal to 110,408,080.
What is the Population growth rate?The population growth rate may be defined as the process that significantly involves the annual average rate of change of population size, for a given state, country, territory, or any geographic region, during a definite time period.
According to the question,
Per capita growth rate (λ)= 0.02 = 1+0.02 = 1.02.
The initial population size is (No) = 100000000.
Time duration (Nt+5) = ?
Now, Nt+5 = (λ)^5 × No = [tex]1.02^5[/tex] × 100000000 = 110,408,080.
Therefore, if a population's per capita growth rate is 0.02 and its population is 100000000, the size of the population after 5 years is equal to 110,408,080.

The differences between two molecules include the type of sugar that forms a section of the molecules and the identity of one of the four nitrogenous bases that make up another section of the molecules. These two molecules are DNA and RNA. They differ in their sugar components (ribose in RNA, deoxyribose in DNA), and in one of the nitrogenous bases (RNA has uracil instead of thymine which is in DNA). This sets the stage for their different roles in the cell.
Explanation:Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are the two molecules that you are referring to. DNA and RNA are both nucleic acids, which are made up of smaller units called nucleotides. Each nucleotide is made up of three parts: a sugar, a phosphate group, and a nitrogenous base.
The type of sugar and the nitrogenous base can vary between the two. In DNA, the sugar is deoxyribose and the nitrogenous bases are adenine, cytosine, guanine, and thymine. In contrast, RNA has ribose as the sugar and its nitrogenous bases are adenine, cytosine, guanine, and uracil instead of thymine.
Furthermore, DNA usually exists as a double helix with two strands running in opposite directions and complementary to each other, while RNA is usually single-stranded. These differences in structure and composition account for their distinctive roles in the cell, with DNA storing genetic information and RNA playing a key role in protein synthesis.

Place the steps for the formation of the enzyme pepsinogen in the correct order.The DNA strands unwind, and
RNA polymerase binds to the
template strand.
The mRNA undergoes intron
splicing and exits the
nucleus.
The tRNA moves through mRNA
with the activated amino acids
attached to it.
The synthesis of mRNA begins.
The amino acids assemble
to form peptide.
The pepsinogen is a protein. All the proteins in the body are coded by the DNA present in the genome. The DNA's 5' -3' strand or the template strand is transcribed by the process of transcription and result in the formation of the mRNA (messenger RNA). the formation of the mRNA by the help of RNA polymerase.
Then the mRNA undergoes the process of maturation. During maturation, splicing of the introns, capping and tailing takes place. The mRNA undergoes translation and forms the amino acids, with the help of tRNA molecule. The tRNA molecules brings the amino acid according to the codon present and these amino acids form a sequence, which later assemble to form a protein.
Hence, the correct sequence would be:
1. The DNA strands unwind, and RNA polymerase binds to the template strand.
2. The synthesis of mRNA begins.
3. The mRNA undergoes intron splicing and exits the nucleus.
4. The tRNA moves through mRNA with the activated amino acids attached to it.
5. The amino acids assemble to form peptide.

Cells have blank of enzymes to act as biological
Cells contain numerous enzymes acting as biological catalysts to speed up essential biochemical reactions. These enzymes interact with specific substrates, and their activity is crucial for sustaining life, exemplified by the health issues arising from enzyme deficiencies in conditions like Sanfilippo Syndrome type B.
Explanation:Cells have a plethora of enzymes to act as biological catalysts. Enzymes are essential proteins in cells that catalyze biochemical reactions by lowering the activation energy required for the reactions to proceed. They are not consumed in the reaction, hence they can be used repeatedly. Substrates are the specific molecules that enzymes act upon, and each enzyme is specific to its substrate. For instance, the enzyme urease catalyzes the reaction involving the substrate urea. Without these biological catalysts, many necessary reactions would not occur rapidly enough to sustain life. An example of this is individuals with Sanfilippo Syndrome type B, who lack a particular enzyme, leading to cellular damage and severe health consequences.
Furthermore, enzymes can be classified according to their function: catabolic enzymes break down substrates, anabolic enzymes build complex molecules from substrates, and catalytic enzymes affect the rate of the reaction. All enzymes serve to increase the rate of chemical reactions, making them vital organic catalysts in living organisms.

Which of the following is FALSE about protein molecules?
A.Their function is a result of their shape and folding.
B.Proteins are made up of strands of glucose and joined together in specific sequences.
C.Protein molecules perform many different functions in the body.
D.The order of the amino acids in the protein is important and helps determine its eventual function.
Answer:
B.Proteins are made up of strands of glucose and joined together in specific sequences.
Explanation:
Proteins are made up of amino acids. An amino acid consists of an alpha carbon connected to an amino group (NH2) and a carboxyl (COOH) group. It also has a side chain 'R' which defines its many properties.
Amino acids link to each other via peptide bonds to form a protein. Two amino acids form peptide bond when amino group from one amino acid forms bond with carboxyl group of another amino acid and a water molecule is released in the process. This reaction is called as condensation or dehydration reaction.
Eventually the function and properties of a protein are determined by the amino acids in it and the way the protein has folded and taken a specific shape. Hence, the statement that proteins are made up of strands of glucose is false.

Materials generally become warmer when light is
Materials warm up when light hits them due to energy transfer. The light energy is absorbed by the material and transformed into heat energy, similar to how sunlight warms the earth or a car's interior.
Explanation:Materials typically get warmer when light is shined onto them due to a process called energy transfer. Light carries energy, which is absorbed by the material's atoms and converted into heat. This is similar to how sunlight warms the earth.
For instance, when sunlight hits a car's windshield, the car interior heats up. This is because the light energy is absorbed by the car's interior surfaces and transformed into heat energy.
This principle is also used in solar panels, where light energy is transformed into electrical energy. The warmth you feel when light hits an object is an indicator of this energy transformation.

when animals excrete nitrogenous wastes into the soil certain soil bacteria convert these wastes into nitrates, which are absorbed by plants. These soil bacteria function as
A) autotrophs
B) secondary consumers
C) Decomposers
D) Abiotic factors
The correct answer is C. Decomposers
Explanation:
In ecology, decomposers are organisms such as bacteria that mainly decompose or break in smaller particles dead organism or waste produced by them and by doing this, they return nutrients of the living organisms to the soil. Due to this, decomposers are essential for the natural cycle of many substances and they are in the last stage in many food chains. According to this, the soil bacteria described has the function of a decomposer because this breaks down the wastes returning essential nutrients such as nitrates to the soil.
