Nady [450]3 years ago
5 0

Answer:

In explanation.

Explanation:

Causes: most veld fires are a result of human actions that emanate from the disposal of cigarettes, the burning of vegetation when preparing fields, the use of fire by hunters, smoking out bees and the making of fires by motorists along highways.

Effects:  land management and sustainability posed by veld fires include property damage, reduced soil fertility, destruction of vegetation, air and water pollution, and destruction of wildlife.

Practical solutions:

1. Prepare fire breaks on their side if there is a reasonable risk of veld fires.

2. Have the necessary equipment, protective clothing, and trained personnel to extinguish these fires.

3. Avoid throwing cigarettes butts on the ground.

4. Have grass beaters handy to extinguish the fire.

5. Always have the emergency number handy to call emergency services 10177 on Telkom landlines or 112 on your cellphones.

6. Sand can be a very effective method of veld fire control since water will not be readily available.

7. Visit your nearest Basic Emergencies, Safety And Fire (Besafe) center for more information on fire safety education.

Saprophytes are fungi that feed on dead and decomposing organisms
UNO [17]

Saprophytes are fungi that feed on dead and decomposing organisms they secrete enzymes that digest additives of cell walls, including cellulose and lignin.

<h3>Why are fungi called as the saprophytes?</h3>

Fungi purpose decay through liberating enzymes onto the lifeless animal or plant. These smash down complicated compounds into easy soluble ones that may be absorbed through decomposers. Organisms that feed on lifeless on this manner are referred to as saprophytes.

Saprophytes are residing organisms that stay and feed at the stays of different organisms i.e on lifeless and decaying organisms. Saprophytes, additionally called saprotrophs. They are immensely crucial for soil biology.

As a small change in a person's DNA can cause a genetic disorder
zzz [600]

Affirmative, that is correct.

A genetic disorder is nothing more than an abnormal occurrence in a genome, which means that if you change DNA you'll change the genome, and if the change isn't acceptable, genetic disorders can occur easily.

Genetic disorders is a fun field within genetics, and it isn't easy. The functioning of a gene might be an easy concept now a days, but we haven't mastered it. For example, it's not like maths:

- Somebody comes up with a new, unsolved problem, and tries to solve it, and while doing that, the person can create laws, theorems, equations, etc.

Once you come up against a genetic disorder (you can't just create a genetic disorder to study it) you have to study the genetic disorder itself, what caused it and why.



Hope it helped,
