The advantage for the reduced gametophytes in seed plant is that they gain nutrients from the sporophytes
Gametophytes are microscopic and have capacity to develop from spores retained in the sporangia of parental sporophyte. This kind of arrangement protect developing gametophyte from environment stress which enable it to gain nutrient from sporophyte.
Answer:
Answer: 2
Explanation:
I do not not know a VOC resource is, but it is not the answer. The answer is B, a rapidly renewable resource.
Somethings are by products. Silver and Gold can be byproducts of copper, but Bamboo is a primary resource. You use it as soon as you grow it.
Answer 2
For staining flagella of bacteria use actively motile organisms 20 to 24 hours old, allow to diffuse in sterile water 20 to 30 minutes, transfer droplets of the suspension to clean slides and let evaporate without spreading. Then treat 2 to 4 minutes with the following mordant: tannic acid 10 or 20%, 50 cc.; ferric chloride 5%, 10 to 15 cc.; carbol fuchsin (Ziehl-Nielson), 5 cc.; hydrogen peroxide 3%, 6 to 8 cc. Wash and stain 2 to 3 minutes with a mixture of basic fuchsin, saturated alcoholic, 10 cc.; anilin oil (1 part) and 95% alcohol (3 parts) mixed, 5 cc.; distilled water, 30 cc.; acetic acid, 4%, 1 cc. Wash thoroly with water.
Answer:
C. 25°
Explanation:
Prepare a sketch such that the first line with points VRS intersect the line with points TRW at R where ∠WRS and ∠VRT are vertical angles.
Because line TW intersect line SV at R, then ∠WRV and ∠SRT are vertical angles.
The sum of ∠SRT and ∠VRT =180°
Thus (25x +30)°+(5x)° =180°
25x +30° +5x =180°
30x= 180°-30°
30 x = 150°
x= 150/30
x= 5°
∠SRT = 25x+30 = 25*5 +30 =155°
∠WRS= 180°-155°=25°
There are two types of cells. One is an animal cell, which has the mitochondria, and the other is a plant cell, which I believe does not have the mitochondria.
Hope this helps!
