Explain how fitness can change the allele frequency of a population. PLZ no link
Answer:
Natural selection can cause microevolution (change in allele frequencies).
Explanation:
With fitness-increasing alleles becoming more common in the population.
Fitness can affect the survival and reproduction rates of individuals with different alleles, leading to differential contribution to the next generation and changes in the frequency of these alleles in the population.
What is fitness?Fitness is a measure of the reproductive success of an individual within a population. The fittest individuals are those that are most successful at passing their genes on to the next generation. When the environment changes, the selective pressures on a population also change. This can lead to changes in the relative fitness of different individuals, and thus changes in the allele frequencies of a population over time.
For example, if a population of birds lives on an island with small seeds, those birds with small beaks may be more fit than those with larger beaks. This is because they are better adapted to the environment and can more easily obtain food. Over time, the frequency of the small-beaked allele will increase in the population, while the frequency of the large-beaked allele will decrease.
Thus, fitness can drive changes in the allele frequency of a population over time by favoring those individuals with alleles that are better adapted to the environment.

muscle cells are said to have what characteristic because they can respond to stimulation from the nervous system?
Answer:
Muscle cells are excitable; they respond to a stimulus. They are contractile, meaning they can shorten and generate a pulling force. When attached between two movable objects, in other words, bones, contractions of the muscles cause the bones to move.

6. Identify the type of climate data that has the longest data range. 1. microscopic organism 2. data sediment core 3. data tree ring 4. data ice core data
Complementing data, taken from different sources such as tree rings, sediments, and ice, provides significant information about global climatic changes. However, ice core data has the longest data range. (4) is correct.
-------------------------------
Ice core data refers to the information obtained from a sample of ice taken from a glacier or a mountain.
Information kept in the ice is mostly about gases concentration at different moments though time.
Analysis of retained gases in Antarctic ice, through perforations of over 2000 meters deep, has allowed knowing the CO₂ atmospheric concentrations and other gases involved in the greenhouse effect for at least 150,000 years.
These concentrations have varied in the temporal scale of glaciation, showing low concentrations during glacial periods with low temperature and relatively high concentrations during interglacial periods with high temperature.
Between these two periods, abrupt variations in temperature and gas concentration are detected, meaning that changes in CO₂ cause changes in temperature.
The increase in CO₂ is a highly significant component in global climatic change and possibly the best documented.
This information is the best paleoclimatic documents.
Complementing it with marine sediments core and data tree rings makes it possible to know about the principal traits of terrestrial weather in the lasts 420,000 years, practically four glacial-interglacial cycles.

View Available Hint(s)for Part A increase the free energy of the reactants to make the reaction go faster provide activation energy for the reactions they facilitate can alter the free energy change (ΔG) for a chemical reaction are proteins increase the rate of a reaction without being consumed by the reaction
Answer:
Enzymes are proteins that are able to increase the rate of a reaction without being consumed by the reaction. They are also called natural catalysts.
Explanation:
Enzymes increase the rate of chemical reactions inside cells by lowering the activation energy required for the reaction to proceed.
