Bacteria from the soil absorb nitrogen from the air and convert it into ammonium. This is an example of _____.the hydrologic cycle
nitrogen fixation
assimilation
carbon cycle

Answers

Answer: Nitrogen Fixation

Explanation:

The bacteria that is present in the soil converts the atmospheric nitrogen into the form that can be used by the plants.

The form of nitrogen that is present in the atmosphere is not used by the plants has to be first converted in the form which can be used by the plants.

These bacteria are found in the roots of the legumes which gets food from the roots of the plant and fixes nitrogen for the plant.

Hence, the correct answer is option B
nitrogen fixation

The Mute Swan is a species of bird with an orange-reddish bill and white feathers. It is naturally found in Europe and Asia but can sometimes be found in the United States as a result of the importation of these non-native birds.Mute Swans are one of the heaviest flying birds and consume up to 8 pounds of vegetation each day. How will the migration of Mute Swans into an area most likely affect the birds native to that area?

Answers

the native birds will decrease in numbers because there is not enough food for all the birds.
First off, because the bird is non native it may introduce new diseases. Second, because it eats so much vegetation, birds may lack materials to build nests or dens.

Which individuals in the pedigree are identified and labeled carriers for red-green color blindness?

Answers

Do you have the pedigree to share? Red green color blindness is an x linked trait, which means that it is found on the X chromosome. X linked traits are often recessive, and this is why they usually show up in males, such as the case of red green colorblindness. A male has only one copy of the X chromosome, so if a recessive x linked trait is present, he does not have the option of the dominant version of the trait to show up. A recessive X linked trait can present itself in a female, but since she has two X chromosomes, she would need to have two copies of the recessive trait for it to present itself. This is why color blindness is less common, but still possible in females. I hope this helps you with your pedigree.

Given the mRNA sequence GGU-GCU-CCU-AUU, what would be the sequence of tRNA anticodons?

Answers

Answer:

CCA-CGA-GGA-UAA

Explanation:

The sequence of the tRNA anticodons will be complementary to the mRNA coding sequence. This complementary pairing is very necessary for the correct protein to be transcribed as it allows the right amino acid to be supplied.

The sequence for tRNA anticodons would be CCA-CGA-GGA-UAA. This is because the base Guanine (G) always pairs with the base Cytosine (C). The base Adenine (A) pairs with Thymine (T) in case of DNA and Uracil(U) in case of RNA.

Answer:the answer is b
