Explanation:
Plants usually absorb nitrogen from NO3- and NH4+
Nitrogen oxides released into the atmosphere by burning fossil fuels and organic matter is not a source of nitrogen which is available to plants. Thus, the correct option is D.
How does plants take nitrogen?Plants require nitrogen as it is a macronutrient. The deficiency of this nutrient can cause many diseases. However, plants cannot themselves obtain the nitrogen from air but they rely mainly on the supply of combined nitrogen atom in the form of ammonia molecule, or nitrate molecule, resulting from the nitrogen fixation through free-living bacteria in the soil or the bacteria living symbiotically in the nodules on roots of legumes.
Plants can take nitrogen through absorbing the soil by their roots. Plants cannot get this nitrogen directly from the air. Although, the nitrogen element is abundantly available in air. Nitrogen is unreactive atom, and it cannot be used by the green plants to make proteins. Nitrogen gas needs to be converted into nitrate compounds in the soil through nitrogen-fixing bacteria in soil, root nodules or lightning. Every nitrogen atom is triple-bonded to another nitrogen atom to form the molecular nitrogen, N₂.
Therefore, the correct option is D.

Explain whether continuing to increase light intensity will increase the rate of photosynthesis. Please help!
Answer:
So in the case of a plant, a higher light intensity means more packets of light called “photons” are hitting the leaves. As you rise from low light intensity to higher light intensity, the rate of photosynthesis will increase because there is more light available to drive the reactions of photosynthesis.
Explanation:
If you continue to increase the intensity of light that a plant receives, what happens? The rate of photosynthesis increases with light intensity. The rate of photosynthesis decreases with light intensity. The rate of photosynthesis increases and then levels off.As light intensity increases (distance between lamp and plant decreases) the volume of oxygen (or the rate of bubble production) increases. This indicates that the rate of photosynthesis increases with light intensity.

Complete the following table comparing and contrasting diploid and haploid cells.
Diploid
Haploid
Description
Homologous chromosome pairs
Designated N
Designated 2N
Has one member of each
homologous chromosome pair
Includes gametes
Includes somatic cells
Heart and liver cells
Sperm and Egg cells
Answer:
Please find the description and it's pair below:
Homologous chromosome pairs - DIPLOID
Designated N - HAPLOID
Designated 2N - DIPLOID
Has one member of each
homologous chromosome pair - HAPLOID
Includes gametes - HAPLOID
Includes somatic cells - DIPLOID
Heart and liver cells - DIPLOID
Sperm and Egg cells - HAPLOID
Explanation:
1. Diploid organism is an organism with two sets of chromosomes, with each set contributed by each male and female parent. Chromosomes from the male parent is found side by side with chromosomes from the female parent to form HOMOLOGOUS CHROMOSOME PAIR in a diploid organism. Diploidy is denoted by 2N, where N represents number of one set of chromosomes. Diploid cells include somatic or body cells such as heart and liver cells.
2. Haploid organisms are organisms that contain one set of chromosome, formed as a result of meiotic division of diploid cells. Hence, a haploid cell contains one member of each homologous chromosome pair. Haploidy is denoted by N, meaning number of one set of chromosome. Haploid cells include gametes or sex cells such as sperm and egg cells.

What are two ways that variation can be described?
Answer:
varyatio of somthing and multiple varitons of it
Explanation:
The two ways that variation can be described are meiosis and evolution, because in the meiosis process, sexual reproduction occurs, and in the evolution process, changes in animals are seen and variation is observed.
What is variation?When sexual reproduction occurs, there is variation seen because in meiosis genes cross over and recombinate, resulting in variation in offspring from their parents, but it is absent in asexual reproduction that is caused by mitosis or binary fission because here there is no variation in the offspring and the parents. The process of evolution introduces variation because, along with environmental factors, the animal genes are influenced too.
Hence, the two ways that variation can be described are meiosis and evolution, because in the meiosis process, sexual reproduction occurs, and in the evolution process, changes in animals are seen and variation is observed.

Some differentiated cells become senescent almost immediately, leaving the cell cycle and undergoing terminal differentiation. Other cells have a high need to proliferate in order to grow and repair the organ or tissue, so they do not enter senescence for a long period of time. Which cell type would be most likely to put off senescence and terminal differentiation so it could continue to replicate in order to grow and repair?
brain cells
lung cells
skin cells
heart cells
Answer:
skin cells.
Explanation:
for connexus friends
The cell that will most likely put off senescence and terminal differentiation so it could continue to replicate in order to grow and repair would be skin cells.
The skin is a tissue whose cells are constantly dividing to replace old, damaged, or worn-out cells.
Damaged, and worn-out cells are frequent on skin tissues because they directly interact with the environment, exposing them to mechanical, chemical, and other forms of damages.
Thus, the skin cells cannot afford to go into senescence or terminal differentiation due to the fact that they need to constantly divide and replace damaged ones.

TRUE OR FALSE: The molarity of a flaccid plant is equal to the molarity of the solution. The molarity of a turgid plant is greater than the molarity of the solution. The solute potential of a turgid plant is lower than the solute potential of the solution. The molarity of an plasmolyzed plant cell is greater than the molarity of the solution.
Answer:
1. The first statement is true because water movement takes place until it reaches an equilibrium.
2. The second statement is false because the concentration inside the cell will be greater until water moves inside the cell.
3. The third statement is true because solute concentration is high outside.
4. The fourth statement is true because it loses water in a hypertonic solution.

After an ionic bond is formed, what is the charge of the atom that gained an electron?
Answer: Negative
Explanation:
This is called an anion. Whenever an atom gains a electron, it becomes negative. When an atom loses an electron, it becomes postitive. Positive atoms are called cation.
After an ionic bond is formed, the charge of the atom that gained an electron will be negative.
What is an ionic bond?An ionic bond, also widely recognized as an electrovalent bond, is a category of interconnection established by the electrostatic attraction of ions with opposing charge in a chemical substance.
When the valence (outermost) electrons of one atom are permanently transferred to another atom, a bond is formed.
An ionic bond is formed between a metal and a nonmetal, whereas a covalent bond is formed between two nonmetals.
An ionic bond is formed by the complete transfer of electrons from one atom to another. When an atom loses one or more electrons, it becomes a cation, or positively charged ion.
When an atom gains one or more electrons, it becomes an anion, a negatively charged ion.
Thus, the atom is negatively charged as it gained electron.
