Amino acids are similar to carbohydrates and lipids as they all contain carbon, oxygen, and hydrogen.

Amino acids are the organic compounds involved in the synthesis of proteins. The basic structure of amino acids is composed of an amino group, a carboxylic group, a hydrogen atom and a variable R group all bonded with a common α-carbon atom.

Lipids are the organic molecules that consists of fats and oils. The general structure of lipid is composed of a glycerol backbone, with 2 long fatty acid chains attached to each hydroxyl group and a terminal hydroxyl group attached to phosphate group.

Which statements describe planetesimals? Select three options. They are the origins of planets. They formed from gas and dust. T
Anika [276]

A solid minute object that is said to come together for the formation of the planet and are believed to produce cosmic dust are called planetesimal.

The options that best describes the planetesimals are:

  • Option A. They are the origins of planets.

  • Option B. They formed from gas and dust.

  • Option D. They are believed to have developed in debris disks.

The descriptions can be explained as:

  • It is believed that planets formation occurred through planetesimals. The formation happened from gas, dust particles and debris.

  • By the process of accretion, the discs coalesced and became bigger and solid over time. This bigger mass started attracting other matters towards each other because of gravitational force.

  • This pull resulted in either breaking or creation a bigger mass of pieces known as planetesimals. The collision continued to become bigger and solid planets we know today.

Therefore, options A, B and D are correct.

Consider the following hypothetical population and compute the statistical measures below: #births = 50,000; #deaths = 10,000; #
777dan777 [17]

Answer:

The birth rate refers to an average number of births in one year per thousand individuals in the population at mid-year.  

BR = (total birth in an annum / total population in mid year) * 1000

BR = (50000 / 1000000) * 1000 = 50

Death rate refers to an average number of death in an annum per thousand individuals in a population at mid year. Thus,  

DR = (total death / total population in mid year) * 1000

DR = (10000 / 1000000) * 1000 = 10

Annual population growth rate or APGR is calculated as:  

APGR = (Birth rate - Death rate) / Death rate

APGR = (50 - 10) / 10 = 4.0 %

Doubling time is the whole sum time needed for a population to get double in size. It is calculated as DT = ln (2) / growth rate

70 / 4.0 = 17.5 years

Thus, population will get double in 17.5 years.  

Adjusted (true) growth rate is equal to APGR + (NMR / Death rate)

And NMR = [(immigrants -emigrants) / total population] * 1000

NMR = [(5000 - 20000) / 1000000] * 1000 = -15

Thus, Adjusted (True) growth rate = 4.0 + (-15 /10) = -6%

The adjusted (true) doubling time = ln (2) / Adjusted growth rate  

= 70 / -6 = -11.66

This negative sign shows that it will never get double in such situation.
