Explanation:
toxins such as pyrrolizidine alkaloids. By evaluating the risk to livestock from chemical contaminants … ) and the influence of chemical contaminants on livestock production efficiency
Erosion is brought about by the forces of nature or human activity: water, wind, earthquakes, mining, quarrying, etc. In the desert, there is very little water that can cause weathering or erosion, so the most probable answer is wind or maybe even animal activity.
Answer: Glucose
Explanation: Photosynthesis is a set of chemical reactions that uses energy from the sun and carbon dioxide to produce sugar and oxygen. The sugar provides plants with energy to grow.
Answer:
The correct answer is non-disjunction at the time of meiosis.
Explanation:
A disorder, which takes place in males exhibiting an additional X-chromosome and is an outcome of an error in cell differentiation resulting in anomaly known as the Klinefelter's syndrome. Due to non-disjunction the egg or the sperm may acquire an additional X-chromosome. When these unusual cells take part in the genetic makeup of a person, then that individual most probably suffers from the condition termed as Klinefelter's syndrome.
In the majority of the circumstances, the division of the cells takes place generally during the development of the sperm, and at the same time, there may be certain errors at the time of egg development. Generally, the condition is mostly seen in the offspring of women that conceive after the age of 35.
DNA polymerase is an enzyme which is needed for the synthesis of new DNA strand on the old DNA template. In order to synthesize new DNA strand, DNA polymerase requires many other enzymes or molecules such as:
1. All four deoxyribonucleotides triphosphates
2. Single stranded DNA template
3. Inorganic phosphate 3')H end of new DNA strand
During DNA replication, the double stranded DNA molecules mush unwind and form single stranded structures so the both the strands can be replicated simultaneously.
