A group of students is investigating whether silver is a better thermal conductor than copper. The students take a silver wire a

nd a copper wire of the same length and diameter. They put equal lengths of wax on one end of each wire and dip the other end into a beaker of hot water. The length of wax left on the wires after 10 minutes is shown. Experimental Observations Silver Copper Original length of wax 3.5 cm 3.5 cm Length of wax after 10 minutes 1.2 cm 2 cm What was a control variable in this experiment?

What are the different types of DNA that make up the human genome (one example ""DNA transposons"") Name at least 5 types.
Diano4ka-milaya [45]

Answer:

The correct answer will be-

1. Mobile elemests- LINEs and SINEs

2. Exons

3. Non-coding RNA genes

4. Introns

5.  Repetitive DNA sequence

Explanation:

The human genome represents the total nucleic acids present in the Homo sapiens packaged in 23 chromosome pairs and contains 3 billion DNA base pairs.

The human genome comprises of protein-coding genes and non-protein-coding genes. The protein-coding sequence accounts for only a very small proportion that is 1.5% whereas the rest non-coding sequence accounts for 98.5%.

The non-coding sequence includes the  Non-coding RNA genes( microRNA, small nuclear RNA), Introns which accounts for 26%, Repetitive DAN sequence (50%), mobile elements like LINEs and SINEs and exons.

Thus, Mobile elements- LINEs and SINEs, Exons, Non-coding RNA genes, Introns and Repetitive DNA sequence are the correct answers.

Which factors tend to promote higher biodiversity in an ecosystem? Check all that apply.
aleksandrvk [35]

Answer: diversity of niches

, large area and warm climate

Explanation:

An ecosystem is a biotic community in which the living beings interact with their non-living physical environment. The following factors which are responsible for higher biodiversity in an ecosystem:

Diversity of niches: A niche can be define as the functional role an organism performs in an ecosystem so as to sustain it's life. For example the type of habitat, food and breeding season chosen by the organism. With the increase in the differences in the diversity of niches the organism exhibit variations and differences from the members of the same species or from the members of the other species.

Large area: The large area can support the reproduction and abundance of members which belongs to different species hence will help in promoting higher biodiversity in a region.

Warm climate: The warm climatic range will offer the chances of adaptations to the living organisms to sustain their lives in harsh environmental conditions. This will lead to evolution of  new species from the parent species.
