Answer:

Less plants grow in deserts.

Explanation:

Areas that have more plants have more nutrients. Plants receive and give of nutrients when they die. So areas with little water and plants have little nutrients. Also the sun damages organic matters.

<u>Answer</u>:

<em>Desert soils are poor in organic matter because there are very less plant remains in the soil. </em>

<u>Explanation</u>:

<em>A desert has extreme conditions which support less life.</em> Organic matter in soil called humus is formed by the deposition of dead plants and animals in the soil. <em>Soil contains decomposing microbes which act upon the dead plant and animal remains converting them to organic matter. </em>

In deserts the availability of water is very low which limits the growth of plants there. Animal population is also very less in desert areas.  <em>Above all that the extreme heat of the desert destroys the less amount of organic matter formed. </em>

Evidence suggests that first, ____________ were acquired when an aerobic bacterium was engulfed by larger cells and became mutua
leonid [27]

Answer:

1. Mitochondria

2. Chloroplast

3. the formation of eukaryotic cells

4. DNA

Explanation:

The theory of endosymbiosis was proposed by the Lynn Margulis in 1967 which suggested that the eukaryotic organelles like the mitochondria and chloroplast evolved when another prokaryotic cell engulfed the prokaryotic bacteria.

The mitochondria were formed when the chemosynthetic bacteria were engulfed by the bacteria and the engulfed bacteria formed a symbiotic relationship. Similarly, the chloroplast was originated in the same way when the photosynthetic bacteria were engulfed by another prokaryote.

The evidence which supports their ar:

1. The same size of the organelles to the bacteria

2. The presence of the circular DNA of the organelles like bacteria  

3. The similarity in the 30s and 70s ribosomal subunits.

For two autosomal dominant genes, what is the probability that a cross between two heterozygotes (i.e. AaBb x AaBb) will produce
oksian1 [2.3K]

Answer:

1 in 16

Explanation:

When two heterozygotes (AaBb x AaBb) for two autosomal genes are crossed the expected probability for the offspring is 9 A-B-, 3 A-bb, 3 aaB- and 1 aabb. In other words, out of sixteen offspring, 9 are expected to be dominant on both genes (either homozygous AA or BB or heterozygous Aa or Bb), 3 are expected to be dominant on the A gene but recessive on the b gene, 3 are expected to be recessive on the a gene but dominant on the A gene, and only 1 is expected to be recessive on both genes aabb.
