Due to the decrease of energy at the higher levels of the pyramid, lesser organisms tend to appear at the top of the pyramid.

What is the energy pyramid?

The energy pyramid shows the flow of energy in the ecosystem from one trophic level to another within an ecosystem. We know that from one trophic level to another, only about 10% of energy is transferred among biomass.

The energy that is not transferred is utilized for the metabolic activities of the organisms at that level and then lost as heat. Due to the decrease of energy at the higher levels of the pyramid, lesser organisms tend to appear at the top of the pyramid.

A wheat plant that is light green in color is found growing in a field. Biochemical analysis reveals that chloroplasts in this plant produce only 50% of the chlorophyll normally found in wheat chloroplasts. Propose a set of crosses to determine whether the light-green phenotype is caused by a mutation in a nuclear gene or in a chloroplast gene.

Answers

Answer:

Set of crosses:

Wild-type male x light-green female

Light-green male x wild-type female

Explanation:

Chloroplast genes are inherited maternally and, therefore it would be expected to observe this mode of inheritance:

- Wild-type male x light-green female >> offspring 100% light green

- Light-green male x wild-type female >> offspring 100 % wild-type

Moreover, nuclear genes are inherited from both parents, and, therefore, in the case of complete dominance, it would be expected to observe the following results:

1- When wild type is dominant:

- Wild-type male x light-green female >> offspring 100% wild type

- Light-green male x wild-type female >> offspring 100% wild-type

2- When light-green is dominant:

- Wild-type male x light-green female >> offspring 100% light-green

describing the process of photosynthesis) The process of photosynthesis

Answers

Photosynthesis is the process through which plants obtain their food from sunlight, also,many plants take light energy and convert into chemical energy with the help of chlorophyll pigment (green pigment)......

The process through which green plants and other organisms convert light energy into chemical energy is known as photosynthesis. Light energy is gathered and utilized during photosynthesis in green plants to transform water, carbon dioxide, and minerals into oxygen and energy-rich organic substances.

During this process, water is taken from the soil by the root hairs and transported to the leaves through the xylem vessels. Carbon dioxide enters through the stomata. The chlorophyll breaks water molecules into hydrogen and oxygen by absorbing the sun's light energy.

To produce glucose, carbon dioxide from the air and hydrogen from water molecules are combined. Additionally, as a waste material, oxygen is emitted into the atmosphere through the leaves.

While the rest is stored in the roots, leaves, and fruits for further use, glucose serves as a source of nourishment for plants, giving them the energy they need for growth and development.

Other essential biological elements of photosynthesis include pigments. They are the compounds that give color and absorb light at a certain spectrum while reflecting the light that was not absorbed. Chlorophyll and carotenoids, found in the membrane of chloroplasts, are the main components of all green plants. Its main purpose of it is to absorb light energy.

4. The ATP yield from 2 moles of mitochondrial NADH under aerobic conditions in a eukaryotic cell would be: which option is correct a) 1 mole of ATP b) 2 moles of ATP c) 3 moles of ATP d) 4 moles of ATP e) 6 moles of ATP

Answers

The ATP yield from 2 moles of mitochondrial NADH under aerobic conditions in a eukaryotic cell is approximately 4 moles of ATP.

During oxidative phosphorylation, each mole of NADH can generate around 2.5 to 3 moles of ATP. Therefore, for 2 moles of NADH, the total ATP production would be in the range of 4 to 6 moles of ATP. While the more precise estimate falls within the 4 to 6 moles range, the closest option provided is 4 moles of ATP. It is important to note that the exact ATP yield can vary depending on factors such as the efficiency of the electron transport chain and the specific conditions within the cell.

Since there are 2 moles of mitochondrial NADH, the total ATP yield would be around 4 to 6 moles of ATP. However, the most accurate option among the given choices is 4 moles of ATP.

Answer:

1) This happens in the nasal cavity or nostrils. The cilia (nasal hairs) are the ones responsible for this in which the particles are filtered. Then in the back of the throat is where the nasal cavity and mouth meet is the pharynx.

2) This is the correct function. There are four stages of gas exchange that occur when oxygen is breathed into the body: ventilation, pulmonary gas exchange, gas transport, and peripheral gas exchange. The processes of gas inhalation, exhalation, exchange at the alveoli, transportation to the blood, and subsequent diffusion through different cellular membranes situated in body tissues are described. The lungs contain millions of alveoli, which are surrounded by capillaries. Each bronchiole ends with a collection of tiny air sacs known as alveoli. Capillaries, which are very small blood arteries, surround alveoli. These air sacs are filled with oxygen-rich air from the air you breathe in. The exchange of gases takes place here.

3) It travels down both, not just one. The air travels passed the larynx and into the trachea. The trachea is divided into two tubes which are known as the bronchial tubes. The left one leads to the left lung and the other to the right lung. From here the air is brought to even smaller tubes known as bronchioles.

4) Air enters from the outside during inhalation to either these two openings: nostrils or external nares. The cilia serve the purpose of capturing large inhalation particles. The internal nares are the openings between the nasal cavity and the pharynx. Hence, air enters into the nasal cavity.

5) From the pharynx, air flows through the glottis to the trachea and the cycle continues. The glottis and two or three other cartilages form the larynx, a simple tubular structure in most reptiles.
