deficiency of nitrate ions in plants
Answer:
Plants absorb nitrates in water through their roots. ... Without nitrates, the amount of chlorophyll in leaves reduces. This means leaves turn a pale green or yellow colour. This reduces the plant's ability to photosynthesise and grow properly, which reduces the farmers' crop yield .

if I subtract 20 from my number, then square the result, I get the same answer as if I square my number, then subtract 20 from the result
What is my number and how do you work it out?
The value of the unknown number is 10.5.
Let the unknown number = x
When 20 is subtracted from the number and the result is squared which is equal to the square of the unknown number minus 20:
(x - 20)² = x² - 20
expand the equation;
x² - 40x + 400 = x² - 20
collect similar terms together;
x² - x² - 40x = -20 - 400
-40x = -420
[tex]x = \frac{420}{40}\\\\ x = 10.5[/tex]
Thus, the value of the unknown number is 10.5.

Summarize the lytic cycle. (1 point)
The viral DNA incorporates itself with the host cells and replicates whenever the host cell replicates itself.
A virus copies its genetic material and then splits its cell membranes in half to form identical viruses.
A virus lays eggs on the host cell’s protein coat, which then hatch and move on to infect other cells.
A virus injects its genetic material into the host cell, copies itself, and then forms new viruses that burst out of the host cell.
Answer: A virus injects its genetic material into the host cell, copies itself using the host's structures and resources, and then forms new viruses that burst out of the host cell
The lytic cycle is one of the two main life cycles of viruses, the other being the lysogenic cycle. In the lytic cycle, a virus infects a host cell and hijacks its cellular machinery to replicate and produce new virus particles, or virions.
The correct option is D .
The lytic cycle is rapid and results in the destruction of the host cell. It is often associated with acute infections, where the symptoms of the infection are more severe and appear relatively quickly. Examples of viruses that follow the lytic cycle include the flu virus (influenza), the common cold virus (rhinovirus), and many bacteriophages that infect bacterial cells.
The lysogenic cycle, on the other hand, is characterized by the integration of the viral genetic material into the host cell's genome, allowing the virus to remain dormant for a period before switching to the lytic cycle.
Hence , D is the correct option

How is cytokinesis different in plants and animals?
Answer:
The main difference between plant cell and animal cell cytokinesis is the formation of new cell wall surrounding the daughter cells. Plant cells form a cell plate between the two daughter cells. In animal cells, a cleavage furrow is formed between the two daughter cells.

At the end of binary fission, the two daughter cells that result are genetically _________ to each other and to the parent cell.
A. different
В. identical
C. similar
D. opposite
Answer:
B. identical
Explanation:
In binary fission, the parent cell divides into two. The genetic material (DNA) of the parent cell is duplicated in the daughter cells. Having the same genetic composition makes the cells genetically identical.
Changes in water pressure within guard cells cause the cells to open or close the stomata. This response helps the plant maintain homeostasis by
Answer:
reduced water loss
Explanation:
When the water enters the cells, they swell and become bowed. This causes the guard cells to bend away from each other, thereby opening the stomata. Conversely, when guard cells lose potassium ions, water diffuses out of the cells by osmosis.
The response helps the plant maintain homeostasis by regulating water levels that plants lose during transpiration.
What is cellular homeostasis?The expression cellular homeostasis makes reference to the processes by which an organism maintains an internal state of equilibrium.
Cellular homeostasis is fundamental for the survival of the cell and the organism.Cellular homeostasis in this case indicates the mechanism to maintain concentration and gradients used by the plant to carry out metabolic functions.In conclusion, the response helps the plant maintain homeostasis by regulating water levels that plants lose during transpiration.

1. Why does the angle of the sun at noon seem to change at different months throughout the year?
2. How does this create seasons?
Answer:
1. The earth orbit is slightly elliptical, and the earth axis is tilted by roughly 23.5° to the orbit. These to factors combine to make the an analemma. But in the winter, When the Earth is on the other side of orbit, the Earth's north pole is tipped away from the Sun, so at noon the sun doesn't get as high.
2. The earth's spin axis is tilted with respect to it's orbital planet. This is what causes the season. When the earth's axis points towards the sun. it is summer for that hemispheres. Midway between these two times in spring and autumn, the spin axis of earth points 90 degrees away from the Sun.

Which of the following adaptations helps alpine animals survive the cold winter? a. Reduced lung size b. Low levels of hemoglobin c. Hibernation d. Large legs, ears, and tails.
Hibernation is an adaptation that helps alpine animals to survive the cold winter. Hibernation helps to store energy.
Hibernation is an adaptation that helps to store energy by decreasing the metabolic rate.
This adaptation (hibernation) is observed in animals living in extremely cold conditions (e.g., alpine animals).
The hibernation adaptative strategy is characterized by an excessively low temperature in the body, slow breath rate, slow beats (heart rate), and low metabolic rate.

Answer:
The disadvantages for both cells are that neither is an accurate representation of the cell themselves, or the processes. The first cell doesn't tell us exactly what phases the cell is currently going through, and the cell doesn't go through is phases through grey arrows either. However, it does tell us what the phases look like, and the process of how the cell goes through them. The disadvantages of the second map is that, it doesn't show what the phases look like, the advantages are that tells us what the phases are and what comes before and after them, while showing how this occurs in a cycle and keeps going until senescense.

what part does chlorophyll play in photosynthesis?
Answer:
Explanation:
Chlorophyll's job in a plant is to absorb light—usually sunlight. The energy absorbed from light is transferred to two kinds of energy-storing molecules. Through photosynthesis, the plant uses the stored energy to convert carbon dioxide (absorbed from the air) and water into glucose, a type of sugar

what conditions prompt hemoglobin to release oxygen? select the three answers that are correct.
The conditions that prompt hemoglobin to release oxygen are:
Decrease in pH (high acidity)ExerciseUnloading of oxygen from haemoglobinHaemoglobin is the blood protein that is used to carry oxygen in our body and gives blood its red colour. The ability of this protein to carry oxygen depends on some factor. These factors include:
Decreased pH: Upon the production of carbondioxide in the tissue cells, carbonic acid is produced which leads to decrease in pH of the blood. Exercise: During exercise, the temperature of muscle increases secondary to its utilisation. This will cause the release of unloading of oxygen from haemoglobin.Therefore, conditions that prompt hemoglobin to release oxygen are decrease in pH (high acidity) and exercise.
