Explanation:
What can you infer if the fossil of a marine organism is found in an area that is now dry land?
Answer:
Fossils also help us to infer why dinosaurs and other organisms became extinct. Fossils tell us that there was a mass extinction at the time of the dinosaurs. They died out about 65 million years ago, along with more than half of all the other animal and plant species. ... Without plants, dinosaurs could not survive.

How is genetic variation introduced into a population? Choose all that apply.
I NEED ANSWER ASAP
Answer: Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
Explanation: hope this helps
Gene variants, sometimes known as mutations, can cause genetic differences, or a normal process in which genetic information is rearranged as a cell prepares to divide can also cause genetic variations. Different phenotypes can be introduced into an organism by genetic changes that change gene activity or protein function.
What is mutation ?An alteration in the nucleic acid sequence of an organism's, virus's, or extrachromosomal DNA is referred to as a mutation. DNA or RNA can be found in the viral genome.
Mutation, chance mating, chance fertilization, and recombination between homologous chromosomes during meiosis can all result in genetic variation. Genetic variety is primarily caused by mutations, although it is also influenced by other processes, including genetic drift.
A single nucleotide base can change in a genetic mutation known as a point mutation. DNA mutation, gene flow, and sexual reproduction are the main causes of genetic variation.
Thus,Mutation and genetic recombination are two of the many processes that cause genetic variation.

Would a saturated fatty acid hold more potential energy or less potential energy than an unsaturated fatty acid
Answer:
Yes, it is a fact that saturated fats contain more gross energy due to higher H+ concentration. However, unsaturated fats are more digestible and have higher absorption rate, and therefore the metabolizable energy that unsaturated fats provide is higher than that provided by saturated fats.
Explanation:
28.5g of iron shot is added to a graduated cylinder containing 45.50 mL of water. The water level rises to the 49.10 mL mark, from this information, calculate the density of iron.
Explanation:
this is a very easy question, you just need to know the formula of density, the mass and volume.
you're given the mass of the iron which is 28.5g and when it is submerged into a cylinder containing 45.50 ml, it rises to 49.10 ml. the volume of water displaced gives you the volume of the iron. thus,
V² - V¹ = 49.10 ml - 45.50 ml
V of iron = 3.6 ml
now that you know both the mass and volume, you can work out the question.
density (ρ) = mass / volume
ρ = m/v
ρ = 28.5 g / 3.6 ml
ρ = 7.916666...
ρ = 7.92 g/ml (3 sf)
hope this helps you!
