Describe how the state of matter will affect the usefulness of materials used in a stepping stone

Biology
1 answer:
andrew11 [14]3 years ago
6 0

Answer: The states of matter can be solid, liquid, and gas.

Explanation:

The change in the state of matter can change the utility of the materials. Like, water in the liquid state when changed into solid ice can be used as ice cube and in the gaseous vapors can be used for steaming food items.

The stepping stone is a stone which is used for roadside pavements. It is used for walking. It can be prepared using liquid mixture of cement and concrete into a mold and it is converted into solid mass on drying.

An important physical characteristic of urine is its specific gravity or density, which is?
Maru [420]

Urine's specific gravity, which is somewhat greater than that of water, is a crucial physical property.

Characteristics of urine:

  • Osmolarity is typically harder to quantify than specific gravity, which measures the amount of solutes per volume of a solution. Because there are solutes in urine, its specific gravity is always higher than that of pure water (water = 1.0). Since specific gravity is a less precise predictor of urinary solutes, laboratories may now directly detect the osmolarity of urine.
  • Osmolarity, or mOsmol/L, is the measure of how many osmoles or milliosmoles are present in a litre of a fluid. The osmolarity of urine can range from 50 to 100 to 1200 mOsmol/L of water.

Therefore, it is concluded that the correct solution is an option (D), i.e., slightly higher than water.

The complete question is:

An important characteristic of urine is its specific gravity or density, which is ________.

A. the same as water

B. less than water

C. much higher than water

D. slightly higher than water

Propose an experiment that would test if the RNA component of telomerase serves as a template to extend telomeres. A cell free s
IceJOKER [234]

Answer:

To study the importance of the RNA telomer element, we can evaluate it by generating an in vitro state where all the purified components are included, organizing two groups, one of them will have an RNAase and the other will not, if it is observed that the telomeres extend to the component of the RNA, in the set where there is no RNAase, longer telomeres could be observed, if there were no influence of the RNA, the length in both groups would be the same

Which is not characteristics of all mammals?
alexgriva [62]

Answer:

b. giving birth to live young (viviparous)

Explanation:

Monotremes include duck-billed platypus and few other mammalian species that are oviparous. These mammalian species do not give birth to young ones, that is, they are not viviparous. Rather they lay eggs and are oviparous.

These species are also characterized by the absence of teeth. The primitive monotremes also exhibit external fertilization.

Examples of egg-laying mammals include anteaters or echidnas and the duck-billed platypus. The laid eggs are carried by females in an abdominal ouch to keep them warm.
