Fossils usually occur in metamorphic rock. true or false?
Answer:
false
Explanation:
They can't survive the great pressures metamorphic rocks go through. They usually are only in sedimentary rocks. Hope this helps!
Answer:
false
Explanation:
Fossils are very fragile and metamorphic rocks go through some harsh changes, so i'd be impossible for fossils to stay intact or even form in metamorphic rocks

Based on an analysis of the data, describe the effect of karrikins on seed
germination in the autotrophic host plants and the obligate parasitic weed plants.
Answer:
It triggers seed germination by activating hormone.
Explanation:
Karrikins has a great effect on seed germination in the plants as well as the obligate parasitic weed plants because it trigger the germination of seed by signaling of hormone known as strigolactone which is responsible for the germination of see. Karrikins are the group of plant growth regulators which is present in the smoke of burning plant.

A primary air pollutant is put directly into air by human activity.What is a secondary air pollutant
Answer:
Acid Rain
Explanation:
Acid rain, which is made up of several acidic compounds, forms when sulfur dioxide and nitrogen dioxide react in the air with water, oxygen and other chemicals. On the ground, acid rain damages plants and trees and increases the acidity levels of soils and bodies of water, causing damage to ecosystems. Acid rain also causes decay to buildings and can irritate the eyes and airways.

William wanted to create a report on a geographical location with the greatest species diversity. Which ecosystem can he consider for his report?
Answer:
Forest ecosystem or marine ecosystem.
Explanation:
Forest ecosystem is considered for his report because large number of organisms are present in forest ecosystem. Species diversity is greatest in the geographical location of tropics, particularly in tropical forests. Marine ecosystem is also considered for his report due to the presence of large number of different types of species particularly in coral reef which is a habitat of large number of organism.
A environmental scientist buys 20 gallons of oil eating bacteria to help remediate an area affected by an oil spill. The volume of water the scientist wants to cover with this bacteria is 5 ft³. What volume of water can the scientist cover with the bacteria she purchased? (1 gal = 0.13 ft³)
Answer:
2.6 [tex]ft^3[/tex]
Explanation:
Using the conversion factor:
1 gallon = 0.13 [tex]ft^3[/tex]
Therefore,
20 gallons = 20 x 0.13
= 2.6 [tex]ft^3[/tex]
This means that only 2.6 [tex]ft^3[/tex] out of the 5 [tex]ft^3[/tex] total volume of water the scientist wants to cover can actually be covered by the bacteria that was purchased.
Which of the following could result if meiosis did not occur in the process of sexual reproduction?
What would happen if meiosis did not occur in sexually reproducing organisms?

What type of muscle has a primary purpose of animal movement?
A) cardiac muscle
B) smooth muscle
C) tendons
D) skeletal muscle
Answer:
B. Smooth Muscle
Explanation:
Medusae are among the simplest animals that use muscles to make rhythmic movements. In at least some medusae, the circular muscles, which do most of the work of swimming, are striated. In contrast, most of the other muscles of cnidarians are smooth.
Answer:
D) skeletal muscle
Explanation:
skeletal muscle cells join together to form fascicles, and fascicles form the skeletal muscle.

The middle of an mRNA molecule contains the nucleotide sequence shown here. Much more of the mRNA is translated. Assume that the sequence is translated from left to right.
AUUUAACUGUUCUGUCUAGAG
1.
Construct an Explanation Based only on the information provided, why could the mRNA section be translated into three different sets of amino acids, instead of just one set?
2.
Use Models Use the genetic code to translate the sequence into each of the three possible sets of amino acids.
3.
Draw Conclusions Which of the three sets of amino acids is the most likely to be included in the polypeptide? Explain your reasoning.
Answer:
TAA ATT GAC AAG ACA GAT CTC
1. The more bases there are per codon the more information you can code for. There are only 22 different amino acids, in consequence we need minimum 3 bases per codon.
2. codon
three nucleotides—called a triplet or codon—codes for one particular amino acid in the protein. The nucleotide sequence in the DNA is first transcribed into a molecule of messenger RNA (ribonucleic acid).
3. Known as alpha helices and beta sheets, these stable folding patterns make up the secondary structure of a protein. Most proteins contain multiple helices and sheets, in addition to other less common patterns (Figure 2). The ensemble of formations and folds in a single linear chain of amino acids — sometimes called a polypeptide — constitutes the tertiary structure of a protein. Finally, the quaternary structure of a protein refers to those macromolecules with multiple polypeptide chains or subunits.
OKAY I THINK EVERYTHING IS RIGHT BUT SORRY IF WRONG ;)
3. It is not possible to determine which of the three sets of amino acids is the most likely to be included in the polypeptide based solely on the information provided.
What is a nucleotide sequence?A nucleotide sequence is the order of nucleotides (the building blocks of nucleic acids) in a DNA or RNA molecule.
Nucleotides are composed of a sugar, a phosphate group, and a nitrogenous base, which can be adenine (A), cytosine (C), guanine (G), thymine (T) (in DNA) or uracil (U) (in RNA). The specific order of these nucleotides in a DNA or RNA molecule determines the genetic information that the molecule carries.
