Answer:

Intertidal zone

Explanation:

Intertidal zone is present between low and high tide and hence, it can be above or below water. The zone is characterized by presence of nutrients and abundant oxygen as well as availability of light. The zone exhibits fluctuations in salinity and temperature as caused by waves.

The question is incomplete. The complete question is - A student poured a solution of bromthymol blue indicator into three test tubes. Then, he placed and aquatic plant in two of the test tubes, as shown below. He placed a stopper on each test tube and placed them all in the dark for 24 hours. Brothymol blue turns from blue to yellow in the presence of CO2.

Which process would you expect the organisms in the test tubes to carry out-- cell respiration, photosynthesis or both? When would you expect each process to occur?

Answer:

Photosynthesis is the process of the formation of the food in case of plants in the presence of sunlight with the help of carbon dioxide, water and soil. The light energy is converted into the chemical energy.

The beaker is blue because plants uses carbon dioxide for their food preparation. When the beakers are kept in the dark place, instead of photosynthesis cellular respiration occur that made energy from the food for their survival.

Suggest appropriate sources of food to meet their requirements for a Newborn baby and child aged 6.

pashok25 [27]

Explanation:

Calcium . Helps build strong bones and teeth.

Fat. Creates energy, helps the brain develop, keeps skin and hair healthy, and protects against infections.

Folate. Helps cells divide.

Iron. Builds blood cells, and helps the brain develop. Breast-fed babies should receive iron supplements.

Protein and carbohydrates. They provide energy and fuel growth.

Zinc. Helps the cells grow and repair themselves

Your baby also needs vitamins such as:

Vitamin A. Keeps skin, hair, vision, and the immune system healthy.

Vitamin B1 (thiamine). Helps the body turn food into energy.

Vitamin B2 (riboflavin). Helps the body turn food into energy, and protects cells from damage.

Vitamin B3 (niacin). Helps the body turn food into energy and use fats and protein.

Vitamin B6. Keeps the brain and immune system healthy.

Vitamin B12. Keeps nerve and blood cells healthy, and makes DNA -- the genetic material in every cell.

Vitamin C. Protects against infections, builds bones and muscles, and helps wounds heal.

Vitamin D. Helps the body absorb calcium from food, and keeps bones and teeth healthy. Breast-fed babies may need a D supplement.

Vitamin E. Protects cells from damage, and strengthens the immune system.

Vitamin K. Helps the blood to clot.

In Oompa Loompas, gray face (G) is dominant to orange recessive face (g). If two gray faced Oompas have an offspring with an ora

Neko [114]

Answer:

The genotype for each of the parents must be

parent 1 : Gg

parent 2 : Gg

Explanation:

Please note that a dominant trait is a trait that is expressed phenotypically in a heterozygous state, while a recessive trait is a trait that can only be expressed in a homozygous state.

Now, since gray face (G) for Oompa Loompas is dominant, and orange face (g) is recessive, for an offspring to be orange faced, it means that the genotype of the offspring must be 'gg'. Also, since both parent contribute an allele in the pair of alleles in the offspring, both parents must have the recessive (g) in their genotype. Moreover, we are told that both parents are gray-faced, meaning that their genotypes were 'Gg' and 'Gg'. To confirm, let me do the cross

G g

G GG Gg

g Gg gg

from the cross above, we find out that out of 4 offspring, 3 were gray face (GG, Gg ) while one was orange face (gg).
