How could the nostril and mouth movements of a frog be described when it is using its lungs to breathe?

Answers

Answer 1
Answer: To breath in the air, frog lowers the floor of the mouth. That causes throat to expand and nostrils to open. The air enters the mouth through nostrils and after that nostrils close. The floor of the mouth contracts to push the air into the lungs. To breath out the air, the floor of the mouth is lowered again and the air is pushed into the mouth. Nostrils open again and the air leaves the mouth.

Explain incomplete dominance using snapdragon flowers as an example

Answers

Incomplete dominance is a type of inheritance pattern that occurs in snapdragon flowers.

When none of the factors of a gene is dominant, the phenotype of a heterozygous dominant individual is a blend of dominant and recessive traits called incomplete dominance inheritance pattern.

  • flower color in Mirabilis jalapa (Snapdragon)
  • The red flower is the dominant character and the white flower is the recessive character.
  • There is the blending of the two alleles.
  • The flowers in the F1​  a generation will be pink in color due to the mixing of the alleles

Thus, Incomplete dominance is a type of inheritance pattern that occurs in snapdragon flowers.

Answer:

Pink snapdragons are a result of incomplete dominance. Cross-pollination between red snapdragons and white snapdragons result in pink when neither the white or the red alleles are dominant.

Explanation:

when plants have a red color the dominant trait  the snapdragon flower is crossed with a plant having white color the recessive trait it resulted with a production of the plants with pink flowers you get the intermediate of a red and white flower.

Another Answer:

Incomplete dominance is seen in offspring that have a third phenotype not seen in the parents. Snapdragons are an example. The third phenotype results when a snapdragon with the red pigment protein crosses with a snapdragon with a defective gene that produces no pigment, resulting in a white snapdragon. The offspring receive one allele from each parent, resulting in half the amount of pigmentation for red color being expressed. The offspring will be pink snapdragons instead of red or white.

I need help before 12 o'clock please Which of the following statements describes rill erosion?
A. The population increases next to a shoreline.
B. Sand along a shoreline is repeatedly picked up by waves.
C. Sediment is deposited by a river.
D. Running water cuts small channels into a slope.

Answers

The correct answer is D. Running water cuts small channels into a slope. That's because the running water's force is stronger than the resistance of the land. This causes erosion to occur and the water to carry the material from the land with it, creating a little channel that is usually not that deep but it can go to great lengths.
