Answer:
Clastic sedimentary rocks are made up of pieces (clasts) of pre-existing rocks. Pieces of rock are loosened by weathering, then transported to some basin or depression where sediment is trapped. If the sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock.
Magma forms from the partial melting of mantle rocks. These little blobs of melt migrate upward and coalesce into larger volumes that continue to move upward. As they rise, gas molecules in the magma come out of solution and form bubbles and as the bubbles rise they expand (as outside pressure gets lower).

What is the chemical reaction that lactase catalyzes?
Answer:
galactose and glucose
Explanation:
Lactase catalyzes the hydrolysis of the glycosidic bond in the disaccharide lactose, releasing galactose and glucose hope this worked :)
The chemical reaction that is catalyzed by the enzyme lactase is the breakdown of lactose into glucose and galactose. The reaction is as follows:
Lactose → Glucose + Galactose. (in the presence of Lactase). What is a Chemical reaction?A chemical reaction may be defined as a process through which one or more substances known as the reactants are significantly transformed into one or more different substances known as the products in the presence of enzymes of energy.
Lactose is a type of disaccharide which dissociates into glucose and galactose. It is similar to maltose which in presence of an enzyme maltase gives two different compounds of glucose and sucrose in presence of an enzyme sucrase converts into glucose and fructose.
Therefore, the chemical reaction that is catalyzed by the enzyme lactase is the breakdown of lactose into glucose and galactose.

D. Translate the sequence in the other five reading frames.
The answer is D)Translate the sequence in the other five reading frames. Gene localization by sequencing analysis. Since genes are not just a random collection of nucleotides
How may the genes be located in a DNA sequence?Gene localization by sequencing analysis. Since genes are not just a random collection of nucleotides but instead contain recognizable characteristics, sequence inspection can be used to find them.
These characteristics define whether a sequence is a gene or not, and non-coding DNA does not have them.

Where are steroid receptors generally located and where do they bind the steroid hormone once it enters the cell:____________
A. They are located and bind the steroids in the middle of the cell membrane
B. They are located and bind the steroids in the cytoplasm
C. They are located and bind the steroids on the intracellular membrane surface
D. The receptors are located in the cytoplasm but they bind their ligands in the lysosomes.
Answer: B. They are located and bind the steroids in the cytoplasm
Explanation: Steroid hormones are a class of organic compounds, typically lipids. They bind to protein receptors in the cytoplasm or nucleus of the target cell and thus, their receptors are located inside target cells where they function as ligand-dependent transcription factors. This is to say that hormone-receptor complex formed on binding to DNA activates specific genes that increases production of proteins.
1. John observed bacteria at 100X under the oil immersion and then decided to go back to 40X
objective by raising the oil objective a little to avoid the damage to objective lens. Critique his
technique. (1 pt.)
Answer:
See the answer below
Explanation:
In the first instance, the 100X objective does not have any business touching the slide on the stage so that there would not be any reason to raise it a little in order to go back to a lower objective. At higher objectives, only the fine adjustment should be used to bring the object into focus so as to avoid the objective lens from touching the slide which can damage the objective and or break the slide on the stage.
For the X100 objective to be raised in order to avoid a damage to it, it means John allowed the objective to come too close to the slide in the first place. This should not have been so.

At which point during meiosis do haploid cells first appear?
A. metaphase I
B. anaphasel
c. metaphase II
D. anaphase II
Answer:
D. anaphase II
Explanation:
The telophase is followed by short interphase in which, however, no DNA synthesis takes place, so this phase is not real interphase, which is why it is also called interkinesis. It is followed by another meiotic division, which also consists of four phases marked as prophase II, metaphase II, anaphase II when the spindle fibers pull the chromatids for the opposite poles and telophase II and represent a true mitotic division.
D. anaphase II
Haploid gametes are produced during meiosis, which is a type of cell division that reduces the number of chromosomes in a parent diploid cell by half.
The telophase is followed by short interphase in which, however, no DNA synthesis takes place, so this phase is not real interphase, which is why it is also called inter-kinesis.
It is followed by another meiotic division,
Prophase II: Starting cells are the haploid cells made in meiosis I. Chromosomes condense. Metaphase II: Chromosomes line up at the metaphase plate. Anaphase II: Sister chromatids separate to opposite ends of the cell. Telophase II: Newly forming gametes are haploid, and each chromosome now has just one chromatid.Therefore, correct option is D.

In your Punnett Square activity, you chose beads which represented
genes and used Punnett Squares to determine possible offspring. If
your first parent genotype was yellow bead and blue bead and the
second parent genotype was blue bead and blue bead, how many
offspring out of 4 have the yellow kernel phenotype?
please please!!
Answer:
Two out of four offsprings have the yellow kernel phenotype.
Explanation:
The information that we have is that one parent's genotype is yellow bead (Y) and blue bead (B), and the other parent's genotype is blue bead (B) and blue bead (B).
Parent 1: YB
parent2: BB
If we make a Punnett Square, we can see that two out of four offspring will have the yellow phenotype.
║ B ║ B ║
Y║ YB ║ YB ║
B ║ BB ║ BB ║
The offspring out of 4 have the yellow kernel phenotype in the given case would be - two or 50%
We are given that the kernel color is represented by two beads, yellow and blue beads.
Let us consider yellow bead be represented as Y and blue bead be represented as y. Yellow color is dominant over blue kernel color.parent 1 has a genotype of a yellow bead and a blue bead represented as Yy.parent 2 has a genotype of the blue bead and blue bead, i.e, yy.The cross can be given as,
Genotype Y y
y Yy yy
y Yy yy
Now, two of the four offspring have Yy genotypes.
Thus, 2/4 or 50% of the offspring have a yellow kernel phenotype.

A. Diffusion
B. Endocytosis
C. Exocytosis
D. Osmosis
An amoeba expels large particles by EXOCYTOSIS (Option C).
Exocytosis is the process by which large macromolecules are released from the cytoplasm to the cell exterior.Exocytosis occurs via secretory regions of the cell membrane which are able to excrete waste products and other large macromolecules.Conversely, endocytosis is the inverse process by which a cell takes macromolecules from its surrounding environment.The types of active transport that amoebas use to transport macromolecules are endocytosis (in) and exocytosis (out).In conclusion, an amoeba expels large particles by EXOCYTOSIS (Option C).

Answer:
C The correct sequence of the transfer of information in most organisms is DNA to RNA to protein.
Explanation:
Gene expression involves the flow of information from DNA molecules to the formation of proteins. Information first flows from DNA molecules to RNA through a process called transcription. Transcription is the first step of gene expression in which an RNA especially the mRNA is synthesized from a DNA molecule by RNA polymerase enzyme. Then the synthesized mRNA is taken to the cytoplasm where it undergoes the translation process to form proteins.
