In the interphase, they are really thin, just one strand which is only a few atoms wide (very challenging for an optical microscope and not too easy for the electronic one)
Answer:
c. the height of radish seedlings is measured
Explanation:
Quantitative measurements revolve around the quantity of things and exact measurements. The measured height of a radish seedling is the perfect example of that.
Memory technique:
- <u>Quantit</u>ative observations involve <u>quantit</u>y (numbers).
- <u>Qualit</u>ative observations involve <u>qualit</u>y (descriptions, features, i.e. color, smell, shape)
Answer:
c
Explanation:
Deforestation is a particular concern in tropical rain forests because these forests are home to much of the world's biodiversity. For example, in the Amazon around 17% of the forest has been lost in the last 50 years, mostly due to forest conversion for cattle ranching.
Answer:
2Mg + O₂ → 2MgO
Explanation:
<u>Given reaction is:</u>
Mg + O₂ → MgO
<u>On the right side, we have:</u>
1 Mg, 1 O
<u>On the left side, we have:</u>
1 Mg, 2 O
- Add 2 as a coefficient with Mg on the right side of rxn. (Will make it 2 Mg, 2 O)
- Now, Add 2 as a coefficient with MgO of the left side of rxn. (Will make it 2 Mg, 2 O)
Hence, the reaction is balanced now!
<u>Final and balanced reaction is:</u>
2Mg + O₂ → 2MgO

Two systems most directly interact in the fuzzy millipede's defense against ants are :
<u>muscular and integumentary</u>
<u></u>
Explanation:
- The fuzzy millipede, Polyxenus fasciculatus, is found in Texas and is preyed upon by most species of ants.
- Most millipedes defend themselves with a variety of chemicals secreted from pores along the body, although the tiny bristle millipedes are covered with tufts of detachable bristles.
- Due to their lack of speed and their inability to bite or sting, millipedes' primary defence mechanism is to curl into a tight coil – protecting their delicate legs inside an armoured exoskeleton.
- Reproduction in most species is carried out by modified male legs called gonopods, which transfer packets of sperm to females.
- Millipedes overwinter, so they may hide in cracks or crevices throughout the whole winter and emerge in the spring.
- These insects live in dark, damp places and feed on decaying plant life, sometimes damaging crops. But they can serve a good purpose too.
- To protect itself against the ants, it ejects fibers from a tuft located at the tail end of its body. When an ant attacks, the millipede flexes its back end toward the ant and wipes the tufts against it.
