Charles Darwin was credited for writing the biological theory of __________________. The organisms that were used for the basis of his studies were ___________________.these are the answer choices
A) evolution by natural selection, sweet peas
B) inheritance by independent assortment, sweet peas
C) evolution by natural selection, Galapagos finches
D) inheritance by independent assortment, Galapagos finches

Answers

Answer 1
Answer:

Correct answer: C). Evolution by natural selection, Galapagos finches  

Charles Darwin gave the theory of natural selection in the year 1835 when he visits Galapagos Islands.

There he found several species of finches are adapted to different environmental niches. They have a different shape of the beak, food source they eat and the way they captured the food.

He observes that species vary from island to island, and based on these observations he gave the theory of natural selection.
Answer 2
Answer: The answer is C. He observed how the birds' beak sizes affected their ability to compete for food.

DNA in a solution is negatively charged; if you ran a sample of DNA, what would you predict about its migration?

Answers

Assuming that you ran the DNA sample on an agarose gel. And that you are performing gel electrophoresis. I would predict the sample of DNA moving away from the negative terminal or end and to the positive one. As it is being repelled due to its overall negative charge and thus attracted to the positive end. Both the magnitude of charge and size of DNA sample fragment act as factors and contribute to migration.

How can changes in trophic levels affect an ecosystem’s health and stability?

Answers

Answer:

Changes in the basal levels that are on the bottom of the food chain.

Explanation:

Trophic levels are represented by steps in the food chain. In a simplified diagram, the first basal level is represented by primary producer organisms that include plants and algae. The herbivores are localized in the second place, while in the final levels it is possible to find carnivores and predatory species. It is well known that the changes in the basal trophic levels of this chain (i.e., changes in the first and the second levels) may alter the equilibrium of the food chain and consequently have effects on the stability of the ecosystem.

Why do you think some flora and funna get extinct from the earth ​

Answers

Hey, there!!!!

The main reasons for the extinction of flora and fauna are:

Which two microscopes generate three-dimensional images? scanning electron microscope and scanning tunneling microscope transmission electron microscope and scanning electron microscope scanning tunneling microscope and transmission electron microscope compound light microscope and scanning electron microscope.

Answers

The correct answer is scanning electron microscope and scanning tunneling microscope.  

The SEM refers to a kind of electron microscope, which generates three-dimensional images of a specimen by scanning the surface with a focused beam of electrons. The electrons associated with the atoms in the specimen, generating different signals, which comprise data regarding the composition of the specimen and the surface topography.  

An STM refers to an apparatus for imaging three-dimensional image surfaces at the atomic level. In this, good resolution is regarded to be 0.01 nm depth resolution and 0.1 nm lateral resolution.  

The STM can be utilized not only in a high-ultra vacuum but also in water, air, and numerous other gas or liquid ambient, and the temperatures spanning from 1000 degree Celsius to zero Kelvin.

Absorption of water by a sponge is an example of a ……………..changeIs the given changes are 'reversible' or 'irreversible'?

Answers

⚫Absorption of water by a sponge is an example of a physical change.

⏩The given change (absorption of water by a sponge) is generally considered to be reversible because the absorbed water can be squeezed or evaporated out of the sponge, returning it to its original state.

Final answer:

Absorption of water by a sponge is an example of a reversible change.

Explanation:

Changes can be categorized as either reversible or irreversible. Reversible changes are those that can be undone or reversed, meaning the original state can be restored. On the other hand, irreversible changes are permanent and cannot be reversed to the original state.

Absorption of water by a sponge is an example of a reversible change. When a dry sponge comes into contact with water, it absorbs the water and expands. However, if the sponge is squeezed or left to dry, it releases the water and returns to its original state.

An organism that is heterozygous for a particular character will generally show the recessive trait.a. true
b. false

Answers

An organism that is heterozygous for a particular character will generally show the recessive trait,it is an False statement.

What are heterozygous organism?

  • An organism that has the same two copies of a gene is considered homozygous for that trait, while an organism that has different copies of a gene for a particular trait is considered heterozygous for that trait.
  • In plant and animal breeding, such organisms can be called homozygotes and heterozygotes.
  • For example, a pea plant might have both the alleles "Aa" in its genotype for seed texture, or round ("A") or wrinkled ("a") seeds.

In a heterozygous genotype, the dominant allele overrules the recessive one. Therefore, the dominant trait will be expressed. The recessive trait won't show, but you're still a carrier,so the given statement is considered as FALSE .
