What percent of the sunlight is actually converted into chemical energy via photosynthesis?
kirill115 [55]

Photosynthesis is a process in which green plants and few organisms use sunlight to synthesize their food from carbon di- oxide and water. In plants, during photosynthesis, green pigment known as chlorophyll is involved and oxygen is generated at a by product.

All the sunlight falling on plant is not absorbed. Only half of the falling light which lies in the right frequency to power photosynthesis is absorbed. Out of this falling light, only 8 % to 11% is absorbed by the plant and only 3 % to 6 % is actually used to form chemical energy.

The dominant allele is D and causes dimples and the recessive allele is d and causes no dimples. How would a geneticist describe
SSSSS [86.1K]

A geneticist describes the phenotype of an individual with the alleles dd as homo-zygous recessive. In heterozygous individuals, it is masked by the dominant allele.

<h3>Dominant and recessive alleles</h3>

In diploid organisms, an individual receives two gene forms or 'alleles' for the same gene locus.

An individual is heterozygous when receives two different alleles for the same gene locus, whereas an individual is homo-zygous when receives the same alleles for a gene locus.

In cases of complete dominance, the dominant allele completely masks the recessive allele in heterozygous individuals.

What effect would there be on the final daughter cell if the spindle fibers failed to pull a chromosome toward the pole, as in c
allochka39001 [22]

Aneuploidy can result in the final daughter cell if the spindle fibers fail to pull a chromosome toward the pole as in case of non-disjunction.  

Explanation:

Aneuploidy is a condition which arises when one or more chromosome is missing in the final daughter cells.

Non-disjunction refers to the failure of chromosomal or chromatid segregation or separation during cell division. This results in erroneous meiosis or mitosis leading to the formation of final daughter cells or gametes with an extra or missing chromosome. This condition is aneuploidy.  

Failure of separation or segregation of:

  • Homologous chromosomes occur in Anaphase I, affects four daughter cells.
  • Sister chromatids during Anaphase II, affects two daughter cells

This failure of separation leads to aneuploidy chromosomal abnormalities like monosomy, trisomy, etc which can cause diseases like Down’s syndrome, Turner’s syndrome etc.

Some bacteria live in the roots of plants like soybeans and peas.
PIT_PIT [208]

Answer:

Nitrogen is the most commonly limiting nutrient in plants. Legumes use nitrogen fixing bacteria, specifically symbiotic rhizobia bacteria, within their root nodules to counter the limitation. Rhizobia bacteria convert nitrogen gas (N2) to ammonia (NH3) in a process called nitrogen fixation.

How does a polymer form
liq [111]

Answer:

When many molecules of a simple compound join together, the product is termed a polymer and the process polymerization. The simple compounds whose molecules join together to form the polymers are called monomers. The polymer is a chain of atoms, providing a backbone, to which atoms or groups of atoms are joined.
