When marking an animal for the mark/recapture technique, what can a scientist do to ensure the mark does not lower the organism’s chance of survival, and thus throw off the population estimate?

Answers

Answer 1

Answer: You should make it unobtrusive to avoid it attracting attention or hindering it in any way. What you can do is shave a small patch of fur from underneath the animal, and this couldn't be noticed by predators from sides but could easily be noticed by a scientist that captures it.

Which of the following statements about paper recycling is not true?a. Recycling one ton of newspaper can save 100 trees.
b. Recycling paper can lead to 74% less air pollution.
c. Paper recycling can save on the use of water resources.
d. Recycling paper can lead to 35% less water pollution.

Answers

The statement presented above that is not true about paper recycling is; A) Recycling one ton of newspaper can save 100 trees.

Paper recycling are the processes of reprocessing waste paper such as old newspapers and magazines into new paper products for reuse. Apart from saving trees from being cut, paper recycling has many other significant benefits such as reducing water and air pollution, saving on the use of water resources and energy. For every ton (200 pounds) of newspaper that is recycled, 17 trees are saved.

The false statement here is that; "recycling paper can lead to 35% less water pollution." The idea of recycling a huge environmental conservation effort.

What is recycling?

The term recycling has to do with the process of using a material for the same or another purpose rather than simply disposing the material after it has been used. The idea of recycling a huge environmental conservation effort.

The false statement here is that; "recycling paper can lead to 35% less water pollution."

Which of the following statements helps support the endosymbiotic theory?Choose 1 answer:
A

B

If isolated from a eukaryotic cell, mitochondria can no longer survive and reproduce on their
own.
If isolated from a plant cell, a chloroplast can survive and reproduce on its own.

Answers

Answer:

C. If isolated from a eukaryotic cell, mitochondria can no longer survive and reproduce on their own.

Explanation:

The endosymbiotic theory proposes that early eukaryotic cells evolved from endosymbiotic interactions among prokaryotic cells. This theory states that mitochondria and chloroplasts were once primitive bacterial cells that were ingested by large anaerobic prokaryotic cells, and then these cells benefited from living and working together. The most important lines of evidence that support this theory are that mitochondria and chloroplasts contain their own genetic material (circular DNA) and their own protein biosynthesis machinery (ribosomes).

Final answer:

The statement supporting the endosymbiotic theory claims chloroplasts can survive and reproduce on their own when isolated from a plant cell. This suggests these organelles, once independent prokaryotic cells, retain certain autonomous features despite integration into the eukaryotic cells.

Explanation:

The endosymbiotic theory proposes that certain organelles in eukaryotic cells, such as mitochondria and chloroplasts, originated as independent prokaryotic cells that were engulfed by a host cell. This event allowed a symbiotic relationship to develop, which subsequently led to the development of eukaryotic cells. The option that best supports this theory is: 'If isolated from a plant cell, a chloroplast can survive and reproduce on its own.'

This statement suggests that chloroplasts, like the bacteria from which they evolved, maintain some ability to live independently. Yet, although they contain their own DNA and ribosomes (symbols of their independent past), they are no longer 'free-living'. Similarly, mitochondria are also likely to have been independent entities because they too contain their own DNA and ribosomes. However, having been integrated into the host cell, they can no longer survive on their own, contrary to what might be inferred from the third option. The first and second options simply represent characteristics of all cells and provide no specific support for the endosymbiotic theory.
