How does the acidity of soil affect flower growth?

Biology
1 answer:
Vilka [71]3 years ago

Soil pH can affect plant growth in several ways. Bacteria that change and release nitrogen from organic matter and some fertilizers operate best in the pH range of 5.5 to 7.0 making this the optimum pH range. Plant nutrients leach from the soil much faster at pH values below 5.5 than from soils within the 5.5 to 7.0 range. In some mineral soils aluminum can be dissolved at pH levels below 5.0 becoming toxic to plant growth. Soil pH may also affect the availability of plant nutrients. Nutrients are most available to plants in the optimum 5.5 to 7.0 range. PH can also affect the structure of the soil, especially in clay soils. In the optimum range clay soils are granular and easy to work with. However, if the soil is either extremely acid or alkaline clay, soils tend to become sticky and hard to cultivate.

A pH soil test will tell you whether your soil is within the optimum range or whether it will need to be treated to adjust the pH level. Although the optimum range is 5.5 to 7.0 some plants will grow in a more acid soil and some at a more alkaline level.

PH is not an indication of fertility, but it does affect the availability of fertilizer nutrients. The soil may contain adequate nutrients yet plant health may be limited by an unfavorable pH level. On the other hand, builder’s sand, which is devoid of nutrients, may have optimum pH for plant growth.

Drinking alcoholic or caffeinated beverages increases urine output more than drinking an equivalent amount of water.
olga2289 [7]

Answer:

A) ADH secretion decreases. B) Urine osmolarity decreases.

Explanation:

Antidiuretic Hormone or ADH is responsible for the reabsorption of water through the kidneys.

A) Drinking alcoholic and/or caffeinated beverages decreases the release and effect of ADH so the water does not get absorbed as much as it should, which in turn results in more urination.

B) Osmolarity is a term used to express the concentration of a solution in terms of a certain particle. Since less ADH secretion results in more water being in the urine, this lowers the concentration of the urine. So urine osmolarity would be decreased.

I hope this answer helps.

Which of the following hormones is not produced by the anterior pituitary?
Anarel [89]

Answer:

oxytocin

Explanation:

The pituitary gland is a small gland that divides into two distinct portions, the anterior and posterior lobes, and is located at the base of the brain.

The anterior pituitary, also known as the adenohypophysis, secretes six important peptide hormones, they are:

  • The growth hormone;
  • Adrenocorticotropin;
  • The thyroid stimulating hormone;
  • Prolactin;
  • Two gonadotropic homons - FSH and LH;

Oxytocin is not a hormone produced by the anterior pituitary but by the posterior pituitary, which is known as the neurohypophysis.

PLEASE HELP!!!! A Carp fish has 104 chromosomes. Explain why its germ cells CANNOT go through MITOSIS to create egg or sperm cel
I am Lyosha [343]

Answer:

Mitosis can be described as a type of cell division in which the daughter cells are exactly similar to the parent cell. On the other hand, as a result of meiosis, the daughter cells made have half the number of chromosomes as compared to the parent cell.

The egg cells and the sperm cells divide by meiosis instead of mitosis because when the egg cell and the sperm cell will unite, the resulting zygote will maintain the stable number of chromosomes. For example, the egg cell of the carp fish will have 52 chromosomes, the sperm cell will also have 52 chromosomes. When this egg cell and the sperm cell unite, then only a stable zygote with 104 chromosomes will be formed.

If the zygote had 104 chromosomes and the sperm had 104 chromosomes (if they divided by mitosis), then the resulting zygote would have  208 which will not be stable.
