Answer:
The type of mutation that occurs when one nucleotide in the DNA strand is replaced by another, but the change results in the same amino acid to be placed next in the protein is a silent mutation.
Explanation:
Silent mutations are molecular mutations where, despite a change in one of the DNA nucleotides, this change has no impact on the amino acid sequence that a synthesized protein will have.
An example of a silent mutation is the change in a DNA sequence TTC where a thymine replaces the cytosine, obtaining the TTT sequence:
Normal With mutation
DNA TTC TTT
mRNA AAG AAA
Amino Acid Lys Lys
There was a nucleotide change in the DNA, but the encoded amino acid was the same, which is a silent mutation that does not affect the amino acid sequence of a protein, its structure or function.

What would happen if a cell couldn't make catalase?
Answer:
If hydrogen peroxide is not broken down by catalase, additional reactions convert it into compounds called reactive oxygen species that can damage DNA, proteins, and cell membranes. ... A shortage of this enzyme can allow hydrogen peroxide to build up to toxic levels in certain cells
If hydrogen peroxide is not broken down by catalase, it can be converted into reactive oxygen species, which can damage DNA, proteins, and cell membranes.
What is catalase?Catalase is an important enzyme that uses hydrogen peroxide, a non-radical ROS, as a substrate.This enzyme breaks down and neutralizes hydrogen peroxide to maintain optimal molecular levels within cells.It is also essential for cell signaling processes. The catalase enzyme breaks down hydrogen peroxide (H2O2) into water and molecular oxygen, protecting cells from oxidative damage by reactive oxygen species.Commercially available catalase is produced from Aspergillus niger by a solid-state fermentation process.Peroxidase or catalase is an enzyme of the oxidoreductase class. The peroxidase enzyme catalyzes the breakdown of hydrogen peroxide into water and molecular oxygen as shown.Catalase is a tetrameric heme protein that detoxifies H2O2 into oxygen and water.It is a metalloprotein oxidoreductase and when present in high concentrations he efficiently removes H2O2.To learn more about catalase, refer

Brown-eye color is dominant and blue-eye color is recessive. A brown-eyed man marries a blue-eyed woman and they have a son that has Green eyes. SC.912.1.16.1
What Pattern of inheritance is that?
sex-linked
Co-dominant
Incomplete dominance
O polygenic recessive
Answer: Polygenic recessive
Explanation: Because polygenic dominance describes a relationship between the alleles of a polygenic trait where some alleles are dominant and others are recessive.
This is the pattern of inheritance of Polygenic recessive. So, the correct option is (D).
What is Polygenic inheritance?Polygenic inheritance can be described as the inheritance of traits that are governed by different genes and not just a single gene, and can also be referred to as non-Mendelian inheritance, where traits run like a bell. distributes the sizes and shows the different combinations such as dominant and recessive alleles.
Polygenic traits express several different phenotypes, or displayed characteristics where this inheritance is a type of incomplete dominance inheritance, where the expressed phenotype is a mixture of inherited traits.
Thus, this is the pattern of inheritance of Polygenic recessive. So, the correct option is (D).

Which optical phenomena are formed by cloud droplets?
Answer:
Cloud iridescence
Sunlight travels through the cloud and is diffracted by the droplets, creating the rainbow effect. It can appear as a patch or band at the cloud's edges and changes as the cloud evolves.

Answer:
Cloud iridescence
Sunlight travels through the cloud and is diffracted — or spread out — by the droplets, creating the rainbow effect. It can appear as a patch or band at the cloud's edges and changes as the cloud evolves. Iridescence is mostly seen when part of a cloud is forming and when it is closer to the sun.May 11, 2018

Limestone form as ocean water evaporates and leaves calcium carbonate behind, which is the deposited in the seabed. What type of rock can be formed this way?
Answer:
Sedimentary rock.
Explanation:
Limestone form as ocean water evaporates and leaves calcium carbonate behind, which is then deposited in the seabed. Thus, the type of rock that can be formed this way is a sedimentary rock.
The texture of inorganic land-derived sedimentary rocks is fragmental or clastic. Sediments come from land to form inorganic sedimentary rocks.
Some examples of inorganic land-derived sedimentary rocks are conglomerate, brescia and sandstone.

Bear in mind the biological definition of a species and also the appearance and distribution of the named populations of Ensatina. Which populations could be considered a species separate from E.e. eschscholtzii?
Answer:
E.e. oregonesis
E.e. platensis
E.e. xanthoptica
E.e. croceater
E.e. eschscholtzii
E.e. klaubori
Explanation:
The species mentioned above are probably separate species from E.e. eschscholtzii. this separation occurred due to geographic isolation, where each group of E.e. eschscholtzii evolved creating new species. This type of speciation is called "ring species" and refers to an evolution that is capable of providing species with extremes of variation that are not intercrossed, due to geographic isolation.

Microscopes use lenses to magnify objects. A simple microscope uses only one lens; a magnifying glass could be called a simple microscope. The magnification of a simple microscope doesn't need any calculation because the single lens is usually labeled. A hand-lens, for example, might be labeled with 10x, meaning the lens magnifies the object to look ten times larger than the actual size.

In the wild, the plant Knoxiensus prairieii displays a dimorphic trait for fruit color. The plants will bear either purple or yellow fruits. You find and collect several wild plants from around campus and decide to perform some experiments to determine the relationship between the purple and yellow gene traits. You either perform self-crosses (selfing) or you carefully perform cross-pollination experiments between two plants and obtain the following results:
Pollination Purple Progeny Yellow Progeny
Purple (self) 87 0
Purple (self) 76 24
Yellow (self) 0 95
Purple x Yellow 98 0
Purple x Yellow 52 56
Purple x Yellow 85 0

Copper sulfide is found written as both CuS and Cu2S. Why are there two forms for writing this chemical formula?
SELECT AN ANSWER
This is an example of a combination reaction: CuS is the halfway stage, before the second copped atom joins the molecule.
Copper is a transition metal with two possible ionic states (copper I, or 1+, and copper II, or 2+).
This is a synthesis reaction and so the formula will continue changing until all the atoms have conglomerated.
One of the versions is a mistake, the correct form should be Cu2S.
Answer:
option 3
Explanation:
Copper is a transition metal with two possible ionic states (copper I, or 1+, and copper II, or 2+).
There are two forms for writing the chemical formula because copper is a transition metal with two possible ionic states (copper I, or 1+, and copper II, or 2+)
Copper is a transition metal with variable oxidation states. The oxidation states of copper is what determines the name of CuS and Cu₂S.
Now, we shall determine the oxidation states of copper in each compound.
For CuS:
CuS = 0
S = –2
Cu =?Cu + S = 0
Cu + (–2) = 0
Cu – 2 = 0
Collect like terms
Cu = 0 + 2
Cu = +2For Cu₂S:
Cu₂S = 0
S = –2
Cu =?2Cu + S = 0
2Cu + (–2) = 0
2Cu – 2 = 0
Collect like terms
2Cu = 0 + 2
Divide both side by 2
Cu = 2/2
Cu = +1From the calculations made above, we can see that copper has oxidation state of +2 in CuS and +1 in Cu₂S
Thus, we can conclude that Copper is a transition metal with two possible ionic states and this accounts for the different names of CuS and Cu₂S

Answer:
Predation involves an indivudal creature hunting, killing, and then consuming an animal. An example of this would be a fox hunting a rabbit and then eating it. A parasite is something that can live on or inside another organism, feeding off of it without outright killing it (at least not right away). An example of a parastie would be a tapeworm.

Which statement is true regarding the transmission of sex-linked traits in a population?
O Males cannot carry recessive alleles for sex-linked traits.
O Males cannot express dominant alleles on the X chromosome.
O Males cannot express recessive alleles on the X chromosome.
O Males cannot pass alleles for sex-linked traits to their daughters.
Answer: none of the statements are true
Explanation: Males can have a recessive copy of a X-linked gene, and can pass that on in the X containing gamete and so pass it on to daughters, but not to male offspring. Males will express whichever allele, dominant or recessive that they carry.
