The factor that would least affect photosynthesis is Nitrates in the soil.
Photosynthesis is the process by which plant make their own food by utilizing energy from sunlight, water and carbon dioxide. The limiting factors that affect photosynthesis are the light intensity, carbon dioxide concentration, temperature and water. Without enough light, a plant cannot photosynthesize very quickly, even if there is plenty of water and carbon dioxide.
Answer:
The function of a root hair is to increase the surface area available for absorption in plant roots
Explanation:
Root hairs are located mostly near a plant's root tips. Most water absorption occurs through the root hairs due to its large surface area for absorption of water. The root hairs acts as a protective mechanism to prevent harmful bacterial organisms from infecting the plant via the xylem vessels.
Answer:
C
Explanation:
The dependent variable is always the outcome, data, or what is being measured in an experiment.
<h3><u>Answer;</u></h3>
Chromatin
<h3><u>Explanation</u>;</h3>
- Prophase is the first phase of mitosis, which a type of cell division that takes place in the somatic cells, that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells.
- During this stage the genetic material is called chromatin, which is the complex of DNA and proteins contained in the nucleus.
- During prophase the chromatin is condensed and the chromosomes become more visible. DNA molecules are progressively shortened and condensed by coiling.
Answer:
1/8
Explanation:
The following cross is done:
GGHhmm X GghhMm
If genes are unlinked they assort independently, and we can analyze one at a time to obtain the proportions in the offspring, and then multiply those probabilities to get the proportion of appearance of the GgHhmm genotype.
<u>Gene G/g</u>
P: GG x Gg
F1: 1/2 GG, 1/2 Gg
<u>Gene H/h</u>
P: Hh x hh
F1: 1/2 Hh, 1/2 hh
<u>Gene M/m</u>
P: mm x Mm
F1: 1/2 Mm, 1/2 mm
Total proportion of GgHhmm genotype = 1/2 x 1/2 x 1/2 = 1/8
