Prokaryotes and eukaryotes differ in the presence of the nucleus and the organelles. Prokaryotes are small in size and can easily reproduce and adapt.

Prokaryotes are primitive simple cells that are characterized by single cells with no distinct nucleus and membrane-bounded organelles. Cyanobacteria and bacteria are examples of prokaryotes.

The simple structure of the prokaryotes makes them adapt to environmental changes faster than the complex eukaryotic cell. They have a quick reproduction rate and short life cycles, unlike plants and animals.

The simple and small system of the prokaryotic cell allows the movement and diffusion of the ions and molecules easily. They are extremophiles and can survive harsh environments.

Therefore, small and simple prokaryotic cells are advantageous over eukaryotic cells.

Answer: (B) Redi disproved spontaneous generation.

Explanation: EDGE 2022

Answer:

The radioactive decay causes emission of radiation. Unstable isotopes have a high number of neutrons or protons in their nuclei.

Charles Darwin’s theory of evolution states that evolution occurs by natural selection. Individuals in a species shows variation in physical characteristics. This variation is because of the differences in their genes.

Evolution is the process by which species adapt over time in response to their changing environment.

Individuals with characteristics best match to their environment are more likely to survive, finding food, avoiding predators and resisting disease. These individuals are more likely to reproduce and pass their genes on to their children.

Explanation:

B. Allele frequencies change randomly each generation

Answer:

B

Explanation:

Genetic drift is the alteration of different genotypes in a small population which can cause individuals and organisms getting wiped out, not being able to reproduce, and disappearance. Allele frequencies change randomly each generation in a gene pool (collection of different genes present in a particular population: species in this gene pool have a choice to leave the gene pool or die out).

Best guess is "The populations of the world would soon crowd one another out and make conditions unlivable."

Water pollution is the introduction of pollutants either naturally or due to human activities. Runoff from many farms can result in water pollution.

Water pollution is the contamination of water sources with some pollutants which make the water unusable for the purposes like drinking, cooking, cleaning, swimming, and other activities.

These substances can be chemicals, bacteria, parasites, etc. All sorts of pollution make go to the water directly or indirectly.

One of the prevalent sources of water pollution is runoff from many farms.

Taenia saginata and Taenia solium are the two taeniids of greatest economic and medical importance, causing bovine and porcine cysticercosis and taeniasis in humans. In addition, T. solium eggs can infect humans, often giving rise to fatal neurocysticercosis (12, 39).

Answer:

Annelids are segmented worms whereas roundworms are not segmented. Further, annelids have a true coelom while roundworms have a pseudocoelom. This means annelids have a well-developed mesoderm while roundworms lack a mesoderm.

Prolonged exposure to above-normal oxygen partial pressures, or shorter exposures to very high partial pressures, can cause oxidative damage to cell membranes, collapse of the alveoli in the lungs, retinal detachment, and seizures.

As the world changes, plants and animals change with it. Aside from a few living fossils, the species we see today are very different from species that lived in the past.

A living being that lived more than 11 thousand years ago is considered a fossil, that is, before the Holocene, which is the current geological epoch.

Ancient remains or evidence, but less than 11,000 years old, such as sambaquis, are classified as subfossils.

The dating of a fossil can be done based on the already known percentage of Carbon-14 (C14) in relation to Carbon-12 (C12) of living matter (without decomposition).

Thus, the fossil record can be used to show that organisms changed to meet new conditions.

alright bet I got this

Explanation:

Have you ever wondered what can happen to those plastic bottles you toss away? How do they decompose? What happens to them? Its simple really, they get eaten! No, not by people of course they are eaten by a tiny critter called a wax worm. The wax worms earn their name because they are often found living in beehives where they eat the beeswax.

Wax worms much like mealworms are used to break down things that would normally be endangering to our environment. These seemingly useless little animals do a whole lot for our environment especially with the amount of waste we produce! They really are a tiny secret hero to todays pollution problem.

After quite a few studies scientists are still unsure on how was worms can breakdown plastic with their tiny bodies but they appreciate the work these little recyclers do. They have a lot of theories on how these worms do this one of the theories is that bacteria can break it down, another theory is that enzymes in the worms intestines break down plastics. Though scientists believe it will take a while to figure this out they enjoy studying and learning more about this tiny helper.
