Independent variables cause change. Your independent variable would be acceleration.
Your dependent variable is what is effected. Your dependent variable would be the mass of a cart.
Answer:
When we look at a population, we see that an individual trait may have multiple phenotypes due to <u>genetic</u> variation in the type of protein produced.
Explanation:
The phenotype constitutes the observable traits of an individual, such as height, eye color, and blood group. The genetic contribution to the phenotype is called genotype. Some traits are largely determined by genotype, while other traits are largely determined by environmental factors. Genetic variation is the raw material from which the diverse populations of a species adapt to changes in their environment. New genetic variations arise within populations from spontaneous mutations of a gene or by immigration of individuals from genetically distinct populations. Each chromosome contains many genes, the basic functional and physical units of genetic inheritance. Genes are specific sequences of the bases that encode instructions to form proteins. The DNA sequence is the specific longitudinal arrangement of the bases in the DNA chain. Each gene has a specific DNA sequence. From a common heritage that is the gene endowment of each cell, identical in all of them, the endowment has diverse mechanisms that make it possible to express it differently in each cell and in each individual. That is, although the genetic code and the systems for decoding are basically universal, there are complex differential regulation phenomena that constitute the basis by which each individual responds differently to the environment, and by which each living cell is identified, that is , that the action of a gene, then, is subject to multiple influences external to it, capable of modifying its expressive capacity from the first step, the transcription, to the last, the post-translational transformation of the protein.
Answer;
-Helicase enzyme
Explanation;
-Helicases are enzymes that bind and may even remodel nucleic acid or nucleic acid protein complexes. DNA helicases are essential during DNA replication because they separate double-stranded DNA into single strands allowing each strand to be copied.
-DNA is double stranded. Enzymes that are responsible for replication of DNA can only bind to a single strand of DNA. Helicase is the enzyme that unwinds the DNA by breaking hydrogen bonds between the two strands.It forms the so called replication fork. Other proteins assist helicase to keep the strands apart as long as required for the replication process.
Answer:
Explanation:
'There used to be a number of theories about how the Moon was made and it was one of the aims of the Apollo program to figure out how we got to have our Moon,' says Sara.
Prior to the Apollo mission research there were three theories about how the Moon formed.
Capture theory suggests that the Moon was a wandering body (like an asteroid) that formed elsewhere in the solar system and was captured by Earth's gravity as it passed nearby. In contrast, accretion theory suggested that the Moon was created along with Earth at its formation. Finally, according to the fission scenario, Earth had been spinning so fast that some material broke away and began to orbit the planet.
What is most widely accepted today is the giant-impact theory. It proposes that the Moon formed during a collision between the Earth and another small planet, about the size of Mars. The debris from this impact collected in an orbit around Earth to form the Moon.

<h3>What is
chromatophore?</h3>
The integument and internal organs include pigment-containing cells called chromatophores. Depending on the circumstance, their role is to adapt the body's hue to its environment (e.g., protection, mating behavior, antagonistic displays). The term "disseminated state" refers to the state of the pigment granules when they are dispersed along the chromatophore extensions. The granules are most noticeable in this form, which also gives the chromatophore its distinctive hue. The granules are concentrated and less noticeable when they are removed from the chromatophore extensions.
Crustacean eyestalk ablation causes a significant darkening or lightening of the body color in addition to accelerating the molt (Koller, 1927).
