Answer:
The correct answer is option - C. The tomato yield at the end of the growing season
Explanation:
The dependent variable in research or an experiment is the factors that are being affected by the independent variables. The dependent variable is being tested or measures in an experiment and its measurement alter with the change in an independent variable.
In this research amount of the fertilizer is an independent variable that effect different dependent factors such as temperature, plant size, and sunlight but the tested variable that is tomato yield at the end of the growing season tested by weighing.
Thus, the correct answer is option - C The tomato yield at the end of the growing season.
- Sheet erosion is a type of surface water, and runoff is any water that does not soak into the ground.
Answer:
See the answer below
Explanation:
<em>The DNA of eukaryotic organisms being present in the nucleus while the protein-synthesizing organelle, the ribosome being present in the cytoplasm poses a spatial problem. It means that transcribed DNAs (messenger RNA) in the nucleus would have to somehow be transported to the ribosome in order for the cell to successfully synthesize proteins.</em>
The problem of transporting the messenger RNA is solved by two features of the cell:
- The presence of pores in the nuclear envelop
- The presence of transport proteins in the nucleus
<u>The mRNA binds to the transport proteins to form mRNA-protein complexes and is transported through the nuclear pores, often with the assistance of ATP. </u>
In ecology, the law of conservation of mass is applied by the principle of taking energy from the lower trophic levels and passing it to the higher trophic level by any means.
<h3>What is the law of conservation of mass?</h3>
The law of conservation of mass states that the actual mass in an ecosystem is neither created nor destroyed. Overall remains constant in a system.
In ecology, it illustrates that when an organism is ingested by other organisms, its mass is conserved. Some of the organisms may also be dependent on the waste products like urine and feces to make proteins and other compounds.
Therefore, the energy or mass is neither lost in any form. It simply is taken by other organisms through any means.

Answer: Tightly wound chromosomes, composed of DNA, must unwind before replication. Cell replication splits a cell into two parts, both of which become new, fully functioning cells. Before this can happen, however, cells require a full complement of DNA for each of the new daughter cells that will form as a result of the split. Because of this, DNA makes a copy of itself in a process known as replication during interphase, a stage that occurs before cells divide.
Cell Phases: Mitosis is the process by which parent cells each divide into two identical daughter cells. However, this majority of the cell's time is spent in interphase, during which it performs normal metabolic functions necessary for the organism, such as manufacturing protein. DNA occurs during the S phase of interphase, sandwiched between the G1 and G2 phases. The cell uses checkpoint signals to ensure at the end of G1 that it is big enough to replicate and at the end of G2 to determine whether or not DNA replication has succeeded. If so, the cell can undergo mitosis, at which point DNA winds up tightly for easy transport during the process.
DNA Replication: Replication begins with DNA unwinding and unzipping, its two strands coming apart. While only one side is the “correct” code, containing the actual genetic information used to build the organism’s proteins, both can be the base for a new strand of complete DNA. The enzyme DNA polymerase matches up each base with the correlating base: adenine with thymine and guanine with cytosine. When each pre-existing base has been matched to a nucleotide, which also contains the sugar and phosphate of the DNA’s backbone, the strand is complete.
