times of the year.

What causes this change in fur color?
J Gene expression for fur color is regulated by temperature
G Gene expression for fur color is regulated by latitude.
H The arctic fox has two traits for fur color that are determined at birth.
F The alleles for fur color change as the arctic fox grows older."
Answer:
the correct answer is "J The gene expression for coat color is temperature regulated"
Explanation:
Animals present for the same physical characteristic different phenotypic expressions of the same genome according to the environment in which they are submitted and their affection on them.
The different temperatures makes the fox present different phenotypic manifestations of the same genome, for that reason it is why it changes color and could even change in thickness or quantity.
Which statement best describes the relationship of photosynthesis and energy?
The process of photosynthesis is energy-storing because the process converts light energy into chemical ene
stored in the bonds of glucose.
The process of photosynthesis is energy-releasing because the process converts light energy into free energy
used for cell functions.
The process of photosynthesis is energy-conserving because no energy is used throughout the process of for
glucose and oxygen molecules.
The process of photosynthesis is energy-wasting because photosynthesis is an inefficient process that deplet
energy stored in the bonds of glucose.
Answer:
The process of photosynthesis is energy-releasing because the process converts light energy into free energy
used for cell functions.
which of the following steps happens first during transcription?
Answer:
RNA polymerase attaches to the promoter.
Explanation:i just did it
The following steps happen first during transcription: the RNA polymerase reaches the beginning of a gene that is the second option (B), as the beginning of a gene is the promoter.
What is the significance of the transcription initiation?Transcription initiation has many implications, such as the fact that prokaryotic initiation is different from eukaryotic initiation, where the RNA polymerase first binds at the promoter site of the gene, where it starts moving towards the gene, and then after reaching the termination site, the transcription stops. In this process, the final product is mRNA from DNA.
Hence, the following steps happen first during transcription: the RNA polymerase reaches the beginning of a gene that is the second option, as the beginning of a gene is the promoter.

What happens to an organisms energy storage molecules when it reproduces
An organism's energy storage molecules decrease when it reproduces.
How does energy decrease?As a transfer molecule, ATP, between exergonic and endogenic reactions, energy is quickly depleted.
When cells divide during mitosis or meiosis, ATP and NADPH are used to power the processes.
As mitochondria are randomly distributed, their ATP generation continues because ATP is not stored but is constantly used.
The hydrolysis of ATP results in the formation of ADP, inorganic phosphate ion, and the release of free energy.
To carry out life processes, ATP is constantly broken down into ADP, and ADP, like a rechargeable battery, is constantly regenerated into ATP through the reattachment of a third phosphate group.
Thus, we can conclude that energy decreases when organisms reproduce.

Base your answers to question 8 on the information below and on your
knowledge of biology. Evolution leads to changes in how frequently
certain traits appear in a population. 8) Describe how the process of
natural selection can result in an increase in frequencies of certain traits
found in a population *
Answer:
Natural selection refers the effect of selection pressure on the frequency of allele in the population.
Generally,natural selection increases the chances that certain allele will survive for long period of time, and therefore the chances of successive reproduction. Therefore organisms with these alleles with higher chances of reproduction have high selective advantages, and therefore better adapted to withstand the selective pressure and therefore undergo directional selection within the organisms in the population.
Consequently, they are better reproduced, and thus well populated.The r frequency of their traits is well expressed from generation to generation, and therefore naturally selected, and evolve over long period.

How is water introduceed into rivers and streams
Answer:
As the water flows down, it may pick up more water from other small streams, springs or or from rain or snow melt. ... Small rivers and streams may join together to become larger rivers. Eventually all this water from rivers and streams will run into the ocean or an inland body of water like a lake.Water can be introduced into rivers and streams through surface runoff, springs, groundwater discharge, melting ice and snow, and precipitation. ... The water at the source of the river has high oxygen content, but the width and depth are typically less than they are in the middle sections. The most simplistic answer is that all the water in a river comes from the sky—and that is certainly true, as streamflow is one part of the water cycle. It is also true that most of the water flowing in rivers comes from precipitation runoff from the surrounding landscape (watershed).

During dna replication the wrong nucleotide was inserted in the DNA sequence. Which of the following terms describes the situation? Mutation, translation, regeneration, or transcription.
The situation in which the wrong nucleotide was inserted during DNA replication is referred to as a mutation.
DNA replication is the process by which DNA makes an identical copy of itself. This is critical for cell division during growth or repair of damaged tissues. DNA replication is a highly regulated process that occurs in three stages. Initiation, elongation, and termination are the three stages. The replication of DNA occurs in the nucleus of eukaryotic cells, and it is carried out by several enzymes in a semi-conservative manner.
During DNA replication, the two strands of the double helix unwind and separate. Each single strand then serves as a template for the formation of a new complementary strand. DNA polymerase is the primary enzyme involved in DNA replication. The addition of new nucleotides to the growing strand in a complementary manner occurs in the presence of DNA polymerase.
DNA Replication and Mutation During DNA replication, mistakes may occur. These errors, which can result from damage to the DNA molecule or mistakes made during DNA synthesis, are referred to as mutations. When a mistake is made during DNA replication, the incorrect nucleotide is inserted into the growing DNA strand. This can cause a mutation in the DNA sequence, which can have a wide range of effects, from none at all to severe genetic disorders.
The wrong nucleotide's insertion into the DNA sequence causes a mutation. DNA replication errors can result in a variety of mutations, including base pair substitutions, deletions, and insertions. These mutations can have a range of effects, from none at all to severe genetic disorders, depending on their location and severity.
