Name one sign a plant is deficient in nitrate

Answers

Answer 1

Symptoms include poor plant growth, and leaves become pale green or yellow because they are unable to make sufficient chlorophyll. Leaves in this state are said to be chlorotic. Lower leaves (older leaves) show symptoms first, since the plant will move nitrogen from older tissues to more important younger ones.

Answer 2

Answer:

the leaves will turn a pale green or yellow color

What is the flow of energy in a food web?

The flow of energy in a food web is the transfer of energy from one organism to another as they consume and are consumed by other organisms.

The energy flow in a food web typically starts with primary producers, such as plants, algae, and some bacteria, which convert sunlight or chemical energy into organic matter through photosynthesis or chemosynthesis.

For every higher level, only 10% of the energy of the lower level is transferred.

2. What does the atomic model teach you about the ability of scientists to
study things that cannot be directly observed?

Answers

Answer:

The atomic model is our understanding of how the atom is structured. At one point in history, people believed that any substance was simply made of that substance and would retain that property no matter how small a quantity it was reduced to. Later, some argued that all matter was made of tiny particles called atoms. While this is correct, later researchers found that even the atoms were made of smaller particles called electron, protons, and neutrons. More recently, scientists have discovered quarks, tiny particles that makeup protons and neutrons.

O A. Covalent bonds form from the attraction of positive ions and

freely moving electrons, while Van der Waals forces cause an

attraction between nonpolar molecules.

B. Covalent bonds form when there is an attraction between

nonpolar molecules, while Van der Waals forces cause two atoms

C. Covalent bonds occur when two atoms share valence electrons,

while Van der Waals forces cause an attraction between positive

Answers

Answer:

Covalent bonds form when two atoms share valence electrons,

while Van der Waals forces cause an attraction between nonpolar

molecules

Explanation:

A covalent bond is said to be formed when two atoms of the same or different elements share electrons. In an ordinary covalent bond, each bonding atom contributes one valence electron while in a dative covalent bond only one of the bonding atoms provides the shared pair of electrons.

Van Der Waals forces is the major intermolecular interaction between non polar compounds. Van Der Waals forces " are caused by correlations in the fluctuating polarizations of nearby particles"(Wikipedia).

Answer:

Covalent bonds form when two atoms share valence electrons, while Van der Waals forces cause an attraction between nonpolar molecules.

Answers

Answer:

Blood goes to lungs for the removal of carbondioxide and loading of oxygen whereas kidney filters the blood and sent the waste to urinary bladder.

Explanation:

Blood leaving the chambers and this blood goes to the lungs through pulmonary artery that carries deoxygenated blood. In the lungs, carbondioxide gas is removed from this blood and oxygen is added to the blood. This oxygenated blood goes to the heart through pulmonary vein and the heart pump this blood to all parts of the body. Waste products that is produced during metabolism in the liver will then be transported to the kidney for filtration by the tubules. After filtration the waste products are sent to the urinary bladder through ureters.

What determines the direction of gas movement?

Answers

Answer: The direction of gas movement is determined by partial pressure differences. 2) At the arterial end of the pulmonary capillaries, O2 diffuses from the alveoli into the blood, while CO2 diffuses from the blood into the alveoli.

Explanation:

→ Oxygen and carbon dioxide diffuse across a respiratory membrane.

Factors determining gas movement:

The concentration gradient of the gases and the partial pressure of the gases.The differences in concentration on either side of the cell membrane.

→ In diffusion of gases:

The amount of surface area available for diffusion.The distance the gas particles must travel.The higher the concentration gradient across the gas-exchanging surface, the faster the rate of diffusion across it.

How can poor nutrition lead to a change in trait expression?

Answers

Answer: Poor nutrition won't provide healthy amounts of energy to the body. The lack of nutritional vitamins that the body needs can lead to a change in hormonal signals, stimuli, and metabolites.

Hope this helps :)

In the overall health management, nutrition plays a very recognizable function, however, the role of genetics in nutritional impact is yet to be understood completely.

• Genetic variability in relation to nutrition may be partly accountable for differences among the individuals in metabolism, absorption of food, enzyme digestion, excretion, storage, and others.

• Nutrigenetics and nutrigenomics are the two areas of study regarding genetics and nutrition that looks for the effect of genetic variations on dietary responses, and the function nutrients perform in bioactive food compounds and expression of the gene.

• The three prime factors in nutrigenomics and nutrigenetics are ethnic diversity, malnutrition, and availability of food.

• In the existence of chronic malnutrition, the genomic stability and gene expression can be influenced, with genome stability sometimes resulting in mutations of gene sequences and mutations at the levels of chromosomes.

Thus, poor nutrition can result in the change in the expression of trait.
