c.Stomata are generally open during the day to remove excess water from the planet and closed at night to keep oxygen from escaping.
A generalist species is able to survive in a wide variety of environmental conditions and can make use of lots of different resources. Generalist species have a big niche. Humans, rabbits, house flies, and raccoons would all fall under the generalist species list.
A specialist species can only thrive is a small variety of environmental conditions and/or only has a limited diet. Specialist species have a small niche. Pandas, koalas, and salamanders would all fall under the specialist species list.
Answer:
it damages the earth's atmosphere and harm animals and the air we breath
Answer: C) density-dependent inhibition of growth.
Explanation:
Cancer cells divide rapidly and grow in number abnormally at a rapid rate. These cells are poorly differentiated and they have abnormal membranes, morphology and cytoskeletal proteins.
In density dependent inhibition the cell growth is inhibited and the density of the cells becomes low. The cancerous tumor cells usually loose the density-dependent inhibition.
Answer:
D) A and C
Explanation:
Gram staining is a laboratory technique used for bacterial species. It is used to differentiate between two groups of bacteria based on the components of their cell wall. Gram staining was developed by a scientist called Christian Gram in the year 1884. In the gram stain procedure, the following occurs:
- Due to the thick peptidoglycan component of their cell wall, GRAM POSITIVE bacteria retains the crystal violet due and stain VIOLET.
- On the contrary, due to the thin peptidoglycan component of their cell wall, GRAM NEGATIVE bacteria do not retain the crystal violet dye and hence stain, RED.
Based on this, a bacteria that has been gram stained has been tested for its GRAM REACTION and microscopic morphological characteristics, since it is a microbe.
