Some natural causes of deforestation are:
- Earthquakes (cutting down trees when in the higher scales);
- Biological pests;
- Dessertification process;
- Natural climates changes (seasonality and geological change can lead to natural climate change).
is neurofibromatosis 1 a dominant or recessive trait?
Neurofibromatosis 1 has an autosomal dominant inheritance pattern.
Unlike other types of autosomal dominant conditions, for which one copy of the dominant gene is enough to express the trait/ sickness, for this condition the individual should carry both dominant alleles to trigger the formation of the tumors.
4. Which of the following is most true of fungi?O a They are single celledO b. They are eukaryotesO c They are multicelledO d. They are prokaryotes
The correct option is b. They are eukaryotes
Read each example and decide what the resulting effect on the gene pool of that population would be.
A zebra migrates to join a different herd of zebras.
Competition for sunlight leads to taller trees.
The DNA of a snake changes to make its venom stronger.
A grassfire randomly sweeps through a population of buffalo
and kills most of the animals.
Being a migratory mammal, the zebra moves to several herds as it acquires newer alleles from other populations.
Taller trees result from the fight for sunlight, which may benefit particular alleles. New alleles may be produced from DNA when a snake's DNA is altered to make it deadly. Buffalo rushed across the grass, picking random alleles.
What impact do changes in a population's gene pool have?The size of a population's gene pool is assumed to have some bearing on its capacity for adaptation and evolution. For instance, a population's potential for future adaptability to shifting environmental conditions may be increased by a broad and diversified gene pool.
Genetic variety can be increased by new genes and alleles being created as a result of gene duplication, mutation, or other events.
When individuals leave their family unit or herd to join other populations, this is known as gene flow in animals. New alleles are introduced into populations when people move in and out.

How do humans obtain the minerals needed for the body to function properly?
A.They get them from the water they drink.
B.They take mineral supplements daily.
C.They eat small amounts of rocks to get what they need.
D.They eat healthy foods like meats, vegetable, fruits, and dairy
Answer:
Explanation:
You are supposed to pick D, but that does not eliminate B. Some people do take mineral supplements to keep their mineral needs balanced. Things like Magnesium, Iron Calcium, and others are not in every food you may choose has every ingredient you may need.
I think I would answer D, but don't be surprised if the poser of the question says it is B.
