In what way is surface area more important for cells than volume?
Answer:
As a cell grows in size, the surface area gets bigger, but the volume gets bigger faster. Thinking about this as a ratio (division), the volume is the denominator and the surface area is the numerator. If the volume is getting very big, then the ratio itself will be getting very small.
When the codon and anticodon connect.... What does it build ?
Answer: A tRNA with the complementary anticodon is attracted to the ribosome and binds to this codon. The tRNA carries the next amino acid in the polypeptide chain. The first tRNA transfers its amino acid to the amino acid on the newly arrived tRNA, and a chemical bond is made between the two amino acids.

What is the role of operons in prokaryote gene expression?
Blocks of DNA called operons are used to encode proteins that are required for a certain task or that are part of the same metabolic pathway.
What is operon?Operons are frequently found in bacterial genes. An operon is a collection of genes that all share a single promoter during transcription.
There are regulatory DNA sequences in every operon, and these sequences serve as binding sites for regulatory proteins that either encourage or inhibit transcription. Genes involved in lactose metabolism are found in the lac operon of E. coli. It only expresses itself when lactose and glucose are both absent.
A lactose sensor is the lac repressor. When lactose is present, it ceases to function as a repressor, blocking transcription of the operon in its usual state. Through its isomer allolactose, the lac repressor indirectly detects lactose.
Therefore, Blocks of DNA called operons are used to encode proteins that are required for a certain task or that are part of the same metabolic pathway.

5. The model includes a wavy arrow to show light striking the thylakoids. Which
label for the wavy arrow would be MOST USEFUL for communicating the role of
light in photosynthesis?
a. Light is radiated from the chloroplast during the light-independent reactions.
b. Light energy is cycled within the thylakoid.
c. The chloroplast reflects the green wavelengths of light.
d. Light is the energy source for converting ADP to ATP, and NADP+ to NADPH.
Answer:
There is no model in this question but the question can be answered based on the provided information and general knowledge of photosynthesis. The answer is:
d. Light is the energy source for converting ADP to ATP, and NADP+ to NADPH.
Explanation:
Photosynthesis, which is being described in this question, is the process by which autotrophic organisms synthesize their food in the presence of sunlight. The photosynthetic process occurs in the CHLOROPLAST. However, photosynthesis occurs in two stages namely: light dependent and light independent reaction.
Light dependent reaction occurs specifically in the THYLAKOID of the chloroplast where the photons of light is absorbed by chlorophyll molecule (photosynthetic pigment). The light energy that hits the chlorophyll makes it excited, hence, providing the energy to produce ATP from ADP and NADPH from NADP+.
These products are pivotal in the next stage of photosynthesis (light independent stage). Hence, light plays a very crucial role in photosynthesis by providing the energy source for converting ADP to ATP, and NADP+ to NADPH.

The water cycle describes how water evaporates from the surface of the earth, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls again to the surface as precipitation. ... The cycling of water in and out of the atmosphere is a significant aspect of the weather patterns on Earth.Question 3. Hydropower plants capture the energy of falling water to generate electricity. A turbine converts the kinetic energy of falling water into mechanical energy. Then a generator converts the mechanical energy from the turbine into electrical energy. Question 4. Hurricanes often bring with them a storm surge, which is a broad dome of higher sea level, lifted up by the low pressure in the storm center. ... So, in summary, tsunamis are caused by earthquakes shifting the ocean floor, and hurricanes are big storms that form in the atmosphere over warm ocean waters Question 5 - . Water is generally classified into two groups: surface water and groundwater. In general: Groundwater is located underground in large aquifers and must be pumped out of the ground after drilling a deep well. Surface water is found in lakes, rivers and streams and is drawn into the public water supply by an intake. Question 6: If the material has high permeability than pore spaces are connected to one another allowing water to flow from one to another, however, if there is low permeability then the pore spaces are isolated and water is trapped within them. Question 7 : What's the difference between observational and experimental studies? ... a observational study is where nothing changes and just record what you see, but an experimental study is where you have a control group and a testable group.

If purple flowers are dominant in a plant and white flowers are recessive in that plant, then when purple-flowered
plants with two dominant genes are mated with white-flowered plants with two recessive genes, the first
generation of offspring should have
A
100% white flowers
B
75% purple flowers and 25% white flowers
с
50% purple flowers and 50% white flowers
D
100% purple flowers
im pretty sure it would be c
If purple-flowered plants with two dominant genes are mated with white-flowered plants with two recessive genes, the first generation of offspring should have 100% purple flowers.
Genes are defined as units of inheritance that occur in the chromosomes. Usually, genes occur in pairs called alleles and these alleles control the expressed traits (phenotype) of an organism.
In this case, we have a flowering plant having a dominant gene for purple flowers (R) and a recessive gene for white flowers (r). Using a punnet square, we can see that the first generation will have all purple flowers since it is the dominant gene as shown.
