Biology
1 answer:
larisa86 [58]3 years ago

The correct answer is:

In moss, sperm and egg cells are produced after haploid spores are separated from the sporophyte plant.

Explanation:

The life cycle of most mosses starts with the discharge of spores from a capsule, which begins when a small, lidlike structure, called the operculum, degenerates. A single spore develops to form a branched, filamentous protonema, from which a leafy gametophyte forms.

choli [55]

Answer:

Sulfur; nitrogen.

Explanation:

Acid precipitation results when sulfur and nitrogen compounds react with water in the atmosphere.

This acid precipitation is also known as acid rain and it is typically caused by the chemical reaction between sulfur oxide and nitrogen oxide which are released into the air as a result of burning fossil fuels, with water and other chemical elements present in the atmosphere.

Generally, acid precipitation (acid rain) usually have a pH of about 5.1 or below and as such, it is very acidic nature i.e possessing a large amount of hydrogen ions.

Hence, acid precipitation (acid rain) when washed to the earth has negative or harmful effects on various living and non-living organisms such as animals, plants, cars, buildings etc.

What are the different methods of transport across a membrane ?
dusya [7]
If I remember correctly, there are two main types of transport—passive and active. Passive transport does not require energy or ATP, whereas active transport does.


Types of passive transport include diffusion and osmosis, both of which involve moving down a concentration gradient and thus not requiring energy.


Active transport moves up the concentration gradient and does require energy.

What are the 3 characteristics SIM Media looks for?​
weeeeeb [17]

Answer:

3 characteristic

Explanation:

1- it contains sulfur when bacteria found sulfur in the media then it produces H2S (hydrogen sulfate). It causes the blackening of the media which acts as an indicator that bacteria can produce H2S.

2- Indol is the second characteristic. If bacteria is indol positive than it changes color from yellow to pink when the reagent is added.

3- Motility: if bacteria are motile than it's motility is easily visible in the media.
