one is relative to whats happening now and the other is what happened in the past hope this helped!
Answer:
Relative dating and radiometric dating are used to determine age of fossils and geologic features, but with different methods. Relative dating observes the placement of fossils and rock in layers known as strata. While Radiometric dating, or numeric dating, determines an actual or approximate age of an object by studying the rate of decay of radioactive isotopes

By looking at a plant, how can you tell if it is a cycad and not a palm?
A. look for pollen
B. look for leaves
C. look for roots
D. look for cones
Answer: Look for the cones
Explanation: I took the test and I got it correct.
Cycads are non flowering plants and palms are flowering plants . Therefore, option (D) look for cones.
What are palms and cycads ?Gymnosperms known as cycads are characterised by their massive, pinnately complex leaf crowns and their cones, which are usually carried at the end of the trunk in the middle of whorled branches. Others have partially submerged stems with inflated (tuberous) trunks and tall, unbranched trunks that resemble armor.
There are three different types of palm tree leaves, known as fronds: fans, feathers, and whole leaves. Typically green, palm tree fronds can have a range of textures, such as waxy, smooth, matte, etc.
In gymnosperms, a leafy green sporophyte produces cones with male and female gametophytes. Female cones are larger and higher up the tree. Male gametophytes (pollen) are produced in male cone microsporophylls and carried by wind to female gametophytes.
Therefore, option (D) is correct about palms and cycad.

36. What are the functions of proteins?
37. What foods contain high amounts of protein?
38. What are the four levels of structure found in proteins?
30.Water molecules are polar because they have positive and negative ends, rather like little magnets. Most lipids are non-polar (having no charged areas) or only slightly polar, with a very few charged areas. Water mixes with hydrophilic (water-loving) compounds by sticking to their charged groups.
31.Lipids are detected using the emulsion test. This is what happens: The test substance is mixed with 2 cm 3 of ethanol. An equal volume of distilled water is added.
32.In addition to carbon, hydrogen, and oxygen atoms, all proteins contain nitrogen and sulfur atoms, and many also contain phosphorus atoms and traces of other elements. Proteins serve a variety of roles in living organisms and are often classified by these biological roles.
33.amino acids
For example, proteins are composed of monomers called amino acids. They are linked together to form a polypeptide chain, which folds into a three dimensional (3D) structure to constitute a functional protein
34.Peptide Bonds
Section 3.2Primary Structure: Amino Acids Are Linked by Peptide Bonds to Form Polypeptide Chains. Proteins are linear polymers formed by linking the α-carboxyl group of one amino acid to the α-amino group of another amino acid with a peptide bond (also called an amide bond).
35.A polypeptide is a single linear chain of many amino acids (any length), held together by amide bonds. A protein consists of one or more polypeptides (more than about 50 amino acids long). An oligopeptide consists of only a few amino acids (between two and twenty).

For larger distances such as the distance between objects in the far reaches of our galaxy astronomers ensure in units of?
Answer:
Lightyears
Explanation:
When dealing with very large interstellar distances, astronomers do not use the regular miles, kilometers, or meters we are used to. This is because they are just too small to be used as a metric when measuring such large distances. As a matter of fact, the earthly number system will quickly be exhausted when trying to measure some of these interstellar distances.
Instead, astronomers make use of Lightyears. Lightyears are defined by the distance traveled by an object moving at the speed of light if it was moving constantly at that speed for one year.
This can properly be used to estimate interstellar distances. since its value is very large. 1 lightyear = 9,461,000,000,000 Km
If we say that our closest star is 9 lightyears away, we are saying that it will take an object moving at the speed of light 9 years to travel from that star to our planet.

What is the approximate temperature of the troposphere, mesosphere, and stratosphere.
Answer:
Heat is produced in the process of the formation of Ozone and this heat is responsible for temperature increases from an average -60°F (-51°C) at tropopause to a maximum of about 5°F (-15°C) at the top of the stratosphere. This increase in temperature with height means warmer air is located above cooler air.

Infrared waves have _____ than microwaves. A. More energy B: lower frequency C: longer wavelength D: all of the above
Answer:Option A
Explanation:
Even though microwaves have a little more energy than radio waves, infrared wave has more.
Infrared waves have lower frequency than microwaves. Even though microwaves have a little more energy than radio waves, infrared wave has more.
What is electromagnetic waves?Electromagnetic waves are waves which can travel through the vacuum. electromagnetic waves have electrical and magnetic component associated with them. They all travel with the speed of light. Radio waves, micro waves, infra red and ultraviolet are all electromagnetic waves.
It is visible that wavelength and frequency follow inverse relation. For increase in wavelength, the value of frequency decreases and vice-versa for higher wavelength, the electromagnetic wave will also have lower frequency.
Therefore, Infrared waves have lower frequency than microwaves. Even though microwaves have a little more energy than radio waves, infrared wave has more.
