"Deforestation is the permanent destruction of forests in order to make the land available for other uses. An estimated 18 million acres (7.3 million hectares) of forest, which is roughly the size of the country of Panama, are lost each year, according to the United Nations' Food and Agriculture Organization (FAO)"
The conversion of forests into agricultural plantations is a major cause of deforestation. The increase in global demand for commodities, such as palm oil and soybeans, are driving industrial-scale producers to clear forests at an alarming rate. Indonesia, the largest producer of palm oil, was named the “Fastest Forest Destroyer,” in the 2008 Guinness World Records. Even when efforts are made to replenish barren plantations, the depleted soil is not able to produce the same biodiversity it once was."
Forest clearing for livestock ranching is another contributor of deforestation. Since 1990, Brazil, a top exporter of beef, has lost an area of forest that is three-fourths the size of Texas. A strong global demand for beef, supported by governments such as in Brazil, is expanding this kind of deforestation.

What is the expected phenotype of F1 progeny from a cross between two homozygous recessive mutants disrupted in different genese
LenaWriter [7]

Answer:

The correct answer would be - wildtype.

Explanation:

Let assume there are four genes which are :

A-B-C-D

In mutant first, the genotype would be:---a-b-C-D

In the mutant second, the genotype would be:--A-B-c-d

If both of these genotypes are crossed with each other, the recessive genes a, b of mutant first is dominated and masked the expression by the dominant genes present in the mutant second.

Similarly, the recessive genes of the mutant second are dominated and masked expression by the dominant genes of mutant first.  This is possible only due to different genes are present in mutants.

Thus, the correct answer is - The correct answer would be - wildtype.

I need help with a dang Mono Lake ecosystem thingy
jeyben [28]

Nestled at the edge of the arid Great Basin and the snowy Sierra Nevada mountains in California, Mono Lake is an ancient saline lake that covers over 70 square miles and supports a unique and productive ecosystem. The lake has no fish; instead it is home to trillions of brine shrimp and alkali flies. Freshwater streams feed Mono Lake, supporting lush riparian forests of cottonwood and willow along their banks. Along the lakeshore, scenic limestone formations known as tufa towers rise from the water's surface. Millions of migratory birds visit the lake each year.

From 1941 until 1990, the Los Angeles Department of Water and Power (DWP) diverted excessive amounts of water from Mono Basin streams. Mono Lake dropped 45 vertical feet, lost half its volume, and doubled in salinity.

The Mono Lake Committee, founded in 1978, led the fight to save the lake with cooperative solutions. We continue our protection, restoration, and education efforts today with the support of 16,000 members --and we host this Website.

In 1994, after over a decade of litigation, the California State Water Resources Control Board ordered DWP to allow Mono Lake to rise to a healthy level of 6,392 feet above sea level--twenty feet above its historic low. It is rising toward that goal -- click here for the current lake level, or visit one of the other links on this page for more of the Mono Lake story.

Which of the following is NOT true of enzyme activity? a. enzyme shape may change during catalysis b. the active site on an enzy
Jobisdone [24]

Answer:

D. Each enzyme can catalyze a wide variety of different reactions

Explanation:

Each enzyme can only catalyze a few, specific types of reactions.

Since enzymes and substrates are very specific to one another, enzymes cannot catalyze a wide variety of reactions.

If a substrate is not the correct one that fits in the enzyme's active site, a reaction will not occur.

So, each enzyme can only assist in a few reactions.

The correct answer is D. Each enzyme can catalyze a wide variety of different reactions
