An igneous rock contains one half of its original amount of K(potassium)-40. how old is the rock
Answer: 1.251 billion years

Complete question:
A population of bats feeds on flying insects. Some of these bats have a gene that results in much stronger flight muscles than those of the other bats in the area. Explain how this variation could lead to evolutionary change within this species of bat. In your answer, be sure to include an explanation of
Competition within the bat populationSurvival of various individuals within the bat populationHow the frequency of the trait for stronger flight muscles would be expected to change within the bat population over time.Answer:
Animals with the gene of stronger muscles are better competitors, which means more chances to survive and to reproduce. When they reproduce they pass the gene to the progeny, increasing the allele frequency in the population, probably until fixating it.
Explanation:
Within a population occurs competition among individuals for different resources such a food, territory, refuge, access to females, among others. Feeding habits result in a very important factor that models the species structures, and that might even result in the differentiation of the species into subspecies. Competition for food acts as pressure for animals leading them to develop new strategies for food access. In the exposed example, one of these new strategies is related to a better flight, which is possible due to the gene that results in much stronger flight muscles. Individuals that develop stronger flight muscles are more competitive and probably improve their social status, not only because they can get access to more and better food, but also because this means a better genetic charge which makes them better for mating. These animals have more chances to survive and reproduce: they are stronger and they feed better than the other individuals. The stronger flight muscles are not only useful for feeding, but also for avoiding predators, and for competition. Animals with this gene probably live longer.
Natural selection is the result of the phenotype-environment interaction which determines gene destiny in space and time, selecting beneficial alleles and increasing their frequency in the population. The mutation in the gene of muscle development turns to be beneficial for the species. Animals that carry the gene have more chances to mate and reproduce, and hence to pass the gene to the progeny. In this way, the allelic frequency will increase within the bat population over time.
The study of an environment is called ecology.
The difference in the genes in the given population is called variation and this variation leads to the formation of a new character that has a higher chance of surviving in nature.
These variants have the tendency to choose naturally for the environmental condition.
According to the question, if the bats have the stronger muscle to fly they will reach the prey easily and eat them, before the slow-flying.
This leads to increase competition and the inferior species will extinct due to the higher rate of competition.
Hence, the fast-flying bats are selected naturally and inferior species will extinct.

how do flowering plants reproduce ( secually, asexually, or both
Answer: Flowering plants can reproduce both by sexual and asexual means of reproduction. Sexual reproduction involves the fusion of male and female gametes which takes place through pollination by birds, insects, and water. This pollination causes the fertilization and the female ovules grow into seeds.
Explanation: No need to thank me
Answer: Both, depending on what type of flower the plant is. Some plants reproduce asexually, while other reproduce sexually. Some plants reproduce both ways. Therefore, it depends on the type of flower/plant the flowering plant is.

Answer:
Simple.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Cell staining can be defined as a method used by scientists to view the cells of living organisms and its cellular components with the aid of microscope.
A simple stain uses only one dye to enable the viewer to observe the size, shape, or arrangement of cells. It typically involves the process of soaking a smear (thin film of living microorganisms) in dye and then rinsing it afterwards in order to visualize size, shape or arrangement of cells and other cell organelles such as mitochondria, cytoplasm, nucleus, golgi apparatus etc.

When reproducing, Robins (a species of bird) typically lay four eggs. Laying more eggs might result in malnourished chicks and laying fewer eggs might result in no viable offspring. This is an example of
Answer:
stabilizing selection
Explanation:
The illustration is an example of stabilizing selection.
Stabilizing selection is an evolutionary mechanism in which the extremes of traits are selected against, leading to an increase in the frequency of such traits in the population.
Laying too many eggs would lead to reduced fitness of the population of the bird as a result of malnutrition while laying too few eggs would lead to a reduction in the population. Reproduction needs to be optimized for maximum fitness.
There are different types of natural selection. One of them is stabilizing selection that favors the intermediate phenotype. The exposed scenario is an example of stabilizing selection.
Balancing selection, also called Stabilizing selection, decreases the frequency of individuals with extreme traits, and favors individual that exhibit medium-range characteristics, that gets to survive. Selective pressure is against h0m0zyg0tes, promoting genetic diversity. Genes expressing extreme characteristics in a h0m0zyg0sis are kept in a heter0zyg0us state, as a favorable adaptation to environmental conditions. In a graph, you will see that
→ The curve gets higher and thinner in the middle of the horizontal axe, indicating an increase in the heter0zyg0us genotype frequency.
→ The tails of the curve that coincides with h0m0zyg0us dominant and recessive genotypes frequencies will be near zero.
In the exposed example,
laying more than four eggs and less than four eggs are extreme phenotypes. laying four eggs is an intermediate favored phenotype.
The intermediate phenotype results in the species' fitness increase, so it is favored by natural selection.
Laying four eggs leads to well-nourished chicks, and all of them get to survive. Parents ensure their reproductive success.

Answer:
Nature
Explanation:
Natural selection is when nature decides who survives and who doesn't. Therefore, option A is correct.
What is natural selection?The process through which populations of living things adapt and change is known as natural selection. A population's members are naturally varied, which means that they are all distinctive in some ways. This variety indicates that some people have characteristics that are more environment-appropriate than others.
For instance, giraffes' long necks have allowed them to consume plants that other animals cannot.
Natural selection happens when people with a particular genotype have a higher chance of surviving, reproducing, and passing on their alleles to the following generation than individuals with a different genotype. Hence, option A is correct.
