After examining the fossil record, scientists have determined that scorpions today are much
smaller than their extinct ancestors. For example, Jaekelopterus rhenaniae, a giant scorpion
species that lived 255 million to 460 million years ago, was 2.5 meters long. Which of the
following conclusions is supported by this information?
F Scorpions living today have increased their numbers since they first appeared.
G Scorpions in the fossil record are smaller than their descendants are.
H Scorpions have changed as a result of natural selection,
J Scorpions do not appear in their original state in the fossil record.
After examining the fossil record, scientists have determined that scorpions today are much smaller than their extinct ancestors. Scorpions in the fossil record are smaller than their descendants. Thus option G is correct.
What is fossil ?A fossil is nothing but the impression living organism, commonly observed fossils are from bones, formed from shells, exoskeleton, hairs, skin imprints, and even petrified wood.
Animal footprints, tracks, trails and become fossilized, if a specimen is older than 10,000 years, it qualifies as a fossil. From evolutionary perspective fossils provide the important information and insight about an organism and its habitat.
The bodies of the organisms do fossilize under right environmental conditions, these fossils are called as soft-fossils and leave an imprint of their bodies on the rock.

Amino acids, long considered simply substrates for protein synthesis, have been recently shown to act as modulators of intracellular signal transduction pathways typically associated with growth-promoting hormones such as insulin and insulin-like growth factor-1.
Explanation:
The correct tRNA with the anticodon (complementary 3 nucleotide sequence UAC) binds to the mRNA using the ribosome. This tRNA delivers the correct amino acid corresponding to the mRNA codon, in the case of the start codon, this is the amino acid methionine.
They have been shown to act as modulators of intracellular signal transduction pathways typically associated with growth-promoting hormones such as insulin and insulin-like growth factor-1.

2.Ocean systems:
The ocean is a global, interconnected system that has regions, or basins. Water and ocean life move between these basins and up and down the water column. Ocean water circulates around the globe through ocean currents that are either wind-driven currents or density-driven currents.
3.Proteins:
a class of nitrogenous organic compounds which have large molecules composed of one or more long chains of amino acids and are an essential part of all living organisms, especially as structural components of body tissues such as muscle, hair, etc., and as enzymes and antibodies.
4.Saturated fat molecules:
Saturated fat, a fatty acid in which the hydrocarbon molecules have a hydrogen atom on every carbon and thus are fully hydrogenated. (By way of comparison, the hydrocarbon molecules of unsaturated fats have two carbons that share double or triple bonds and are therefore not completely saturated with hydrogen atoms.)
5.Enzymes:
a substance produced by a living organism which acts as a catalyst to bring about a specific biochemical reaction.
6.Prokaryote:
a microscopic single-celled organism which has neither a distinct nucleus with a membrane nor other specialized organelles, including the bacteria and cyanobacteria.
7.Eukaryote:
an organism consisting of a cell or cells in which the genetic material is DNA in the form of chromosomes contained within a distinct nucleus. Eukaryotes include all living organisms other than the eubacteria and archaea.
8.Hemoglobin:
a red protein responsible for transporting oxygen in the blood of vertebrates. Its molecule comprises four subunits, each containing an iron atom bound to a haem group.
9.Active Transport:
the movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy.
10.Phospholipids:
a lipid containing a phosphate group in its molecule, e.g. phosphatidylcholine.
11.Facilitated diffusion:
Facilitated diffusion (also known as facilitated transport or passive-mediated transport) is the process of spontaneous passive transport (as opposed to active transport) of molecules or ions across a biological membrane via specific transmembrane integral proteins.
Explain three ways classification is helpful.
- It helps in the identification of living organisms as well as in understanding the diversity of living organisms.
- To understand and study the features, similarities and differences between different living organisms and how they are grouped under different categories.
- It is essential to understand the inter-relationships among the different groups of organisms.

A motorcycle weighs 2,009 newtons. The mass of the motorcycle is
kilograms. Use g = 9.8 N/kg for gravity.
Answer: 2009 N / 9.8 N/Kg = 205 Kg.
The mass of the motorcycle is approximately 205 kilograms.
Mass refers to the amount of matter in an object, and it remains constant regardless of the location (e.g., on Earth or in space).
Mass (kg) = Weight (N) / Acceleration due to gravity (N/kg)
Given that the weight of the motorcycle is 2,009 newtons and the acceleration due to gravity is 9.8 N/kg, we can calculate:
Mass (kg) = 2,009 N / 9.8 N/kg ≈ 205 kg
So, the mass of the motorcycle is approximately 205 kilograms. The weight of an object is the force with which it is pulled towards the Earth due to gravity. In this case, the motorcycle weighs 2,009 newtons, which means it experiences a force of 2,009 newtons due to the gravitational pull of the Earth.

What types of substances do not dissolve easily in water?
Answer:
Many substances do not dissolve in water easilyand that is because they are non-polar and do not interact well with water molecules. A common example is oil and water. Oil contains molecules that are non-polar, thus it doesn't dissolve in water so easily.

The main source of energy for both plants and animals is
A. water
B. fertilizer
C. glucose
D. carbon dioxide
Answer:
None of the above.
I'm pretty sure the Sun is the main source of energy.
Explanation:
Here is what I found:
Energy from the sun is the primary source of energy for the earth's ecosystem. The sun's energy is collected and processed by plants through photosynthesis and converted into food for animals. Without the sun, animals would not exist. Food is stored energy and essential elements like carbon, nitrogen and hydrogen.
The main source of energy for both plants and animals is glucose. Therefore, the correct option is option C.
The process of photosynthesis, which plants use to transform solar light energy into chemical energy, makes plants one of a kind. Here, plants use the energy from sunlight to change water and carbon dioxide into glucose, a simple sugar, and oxygen. Plants require glucose as a vital source of chemical energy in order to grow, reproduce, and perform other metabolic functions. The majority of life on Earth gets its energy mostly from this conversion of solar energy into chemical energy. On the other hand, sunlight cannot be used by animals as a direct source of energy. They instead rely on eating plants or other animals to meet their energy needs.
Therefore, the correct option is option C.

Explanation:

That question got me thrown off
Answer:
Dominant
Explanation:
If both of the parents don't express the trait and the child does, then the pedigree is recessive. According to Mendel's law, the recessive trait will only show if there are two recessive alleles. If both of the parents of have the trait and their child does, that means that the parents are heterozygous.
If one of the parents have the trait and the child does or doesn't, then the pedigree is dominant.
