The vials were different shapes is the event could be a source of error. Hence option D is correct.
What is surface tension?Surface tension is defined as the tendency to reduce surface area produced by the tension of a liquid's surface film due to the attraction of the surface layer's particles to the liquid's bulk. Cohesive interactions between the liquid's molecule's cause the surface tension to develop. The molecules at the center of the liquid are surrounded by other molecules on both sides.
The forces that bind molecules of the same type together are known as cohesive forces. For instance, cohesive forces between molecules allow liquids to be kept in open containers. Adhesive forces are those that compel distinct types of molecules to come together. For instance, these pressures induce liquid drops to adhere to window panes.
Thus, the vials were different shapes is the event could be a source of error. Hence option D is correct.

Why would you see different species of animals a million years ago?
Answer:
The earth was completely different 1 million years ago so animals had different features to adapt to the earth. Consider the Wooly Mamoth very similar to an elephant but it had hair due to the cold temperature, now elephants live in Africa where there is no snow so no need for hair

Answer:
En mi opinión, pienso que habrá muchos más animales descubiertos al igual que muchos extinguidos, la verdad no conocemos el mundo completamente y todas sus propiedades, elementos o animales, quizás descubramos animales con dos cabezas o animales más terroríficos, en millones de años pueden ser hasta robots! Quizás, se dupliquen las especies.

Which energy-carrying molecule is produced by photosynthesis?
Answer:
Glucose
Explanation:
Glucose, C6H12O6, is the energy-rich product of photosynthesis, a universal food for life. It is also a six-carbon monosaccharide, or simple sugar.
Glucose.
Photosynthetic cells contain chlorophyll and other light-sensitive pigments that capture solar energy. In the presence of carbon dioxide, such cells are able to convert this solar energy into energy-rich organic molecules, such as glucose.

Explanation:
What would happen to an ecosystem if an invasive
species has no predators? Explain in detail.
Please help!!!!!!!!!!
Explanation:
the top predator is removed from the delicate balance of any particular ecosystem, there may be disastrous effects for the other plants and animals that inhabit the environment.
When a top predator is removed from an ecosystem, a series knock-on effects are felt throughout all the levels in a food web, as each level is regulated by the one above it. This is known as a trophic cascade. The results of these trophic cascades can lead to an ecosystem being completely transformed. The impacts trickle down through each level, upsetting the ecological balance by altering numbers of different animal species, until the effects are finally felt by the vegetation
When a top predator is no longer present, populations of their herbivorous prey begin to boom. Without a top predator to regulate their numbers, these animals put a great deal of pressure on the existing vegetation that they require for food and can destroy large amounts of plant life, such as grasses and trees. This then causes further problems, such as soil erosion and loss of animal habitat. Eventually, humans are also impacted due to the resulting lack of soil fertility and clean water that depend on these plants.
Another problem involving the loss of vegetation is the competition that is created between herbivorous species. Competition between species for the remaining plant life is high and weaker species lose out to stronger ones, leading to the potential loss of weaker animals, as well as plant species. Increased competition, therefore, leads to a lack of biodiversity. In contrast, top predators often have varied diets, which means they can pursue a new food source if one is running low, preventing the first source from being eradicated completely. This is one of the ways that top predators are able to maintain biodiversity and the balance of an ecosystem.
The presence of a top predator also helps to maintain balance in an ecosystem by influencing the behaviour and movements of its prey through the fear of being caught. Animals that are prey to a top predator will move around in order to avoid it. This prevents plants and animals in any particular area of an ecosystem from being over-consumed, preserving food sources and habitats. In the absence of top predators, this regulation disappears, allowing certain areas of vegetation to be destroyed completely.
Answer:
That species would likely run rampid, due to it having no predators. The ecosystem may eventually recover, but it won´t be the same.

A mother with the genotype
Aa displays the dominant
version of the trait. Her
husband displays the
dominant version of the trait.
What version of the trait
would their child display?
A. The child would display the recessive
trait.
B. The child would display the dominant
trait.
C. The child would display some of the
dominant trait and some of the recessive
trait.
D. We need more information about the
father's genotype.
More information is needed about the father's genotype before the version of the trait that would be displayed by the child can be predicted (option D).
What is genotype?Genotype is the part (DNA sequence) of the genetic makeup of an organism which determines a specific characteristic (phenotype) of that organism.
The genotype responsible for a trait in an organism is usually in pairs or versions called alleles. The allele can either be dominant or recessive depending on whether it is expressed or masked respectively.
According to this question, a mother with the genotype "Aa" displays the dominant version of the trait. Her husband also displays the dominant version of the trait.
However, the exact genotype of the father is required to be able to predict the genotypic outcome of their offsprings.
