Answer: Epoch
Explanation: An epoch is the smallest unit of time on the scale, but still encompasses a period of millions of years. Chronologically, epochs are grouped together into larger units called periods. Periods are combined to make a subdivision called an era. An eon is the largest division of geological time.
The smallest division of geologic time is an epoch. Thus, the correct option is D.
What is an Epoch?The geologic time scale is a representation of the time based on the rock record of the Earth. It is a system of chronological dating which uses the process of relating strata to time and the scientific branch of geology that aims to determine the age of rocks.
An epoch or reference epoch is an instant in time which is chosen as the origin of a particular calendar era. The epoch serves as a reference point from which the time is measured.
An epoch is a division of the geologic period and it is the smallest division of geologic time which lasts for over several million years.
Therefore, the correct option is D.

Semi-conservative, daughter molecules have 1 old and 1 new strands, phosphate, 5 carbon sugar, nucleic acid
The pyrimidine bases are?
Answer:
Thymine and Cytosine
Explanation:
Genes are stored within DNA or deoxyribonucleic acids- these are long-chain, macromolecules that form a double helix. They are made up of nucleotides, special monomers made up of nucleotides comprise, 5-Carbon deoxyribose sugar, a nitrogenous base (adenine, guanine thymine, and cytosine) and a phosphate group.
The nitrogenous bases pair up via hydrogen bonding. The pyrimidine bases include cytosine and thymine. In base-pair formation, Adenine forms double bonds with thymine, and cytosine bonds with guanine. These pyrimidines are 6 carbon ringed molecules that contain a double bond.
Human cells have 46 chromosomes. Each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere. Once the chromosome has split, each chromatid is called a daughter chromosome. At the end of cytokinesis how many daughter chromosomes will be found in each cell

Alvin is propelled by ____ hydraulic thrusters and features an electrical system powered by lead-acid batteries. *
Answer:
Alvin is propelled by _gas or diesel___ hydraulic thrusters and features an electrical system powered by lead-acid batteries.
Explanation:
Technically, this implies that Alvin is working on motor-assist mode, using a hybrid engine. Alvin is, therefore, propelled by an internal combustion engine (given the presence of hydraulic thrusters) in addition to an electric motor, which uses energy stored in (lead-acid) batteries. Alvin must be a robot.

Red Blood Cell
Explanation:
Red Blood Cells (RBCs) are round and without a nucleus. It has no nucleus so that it has more space to accommodate oxygen molecules and it helps in diffusion due to the biconcave shape, and that biconcave shape is present because there is no nucleus present in the RBC.

Bart believes that mice exposed to radio waves will become extra strong (maybe he's been reading too much
Radioactive Man). He decides to perform this experiment by placing 10 mice near a radio for 5 hours. He compared
these 10 mice to another 10 mice that had not been exposed. His test consisted of a heavy piece of wood that
blocked the mouse food. He found that 8 out of 10 of the radio waved mice were able to push the wood away. 7 out
of 10 of the other mice were able to do the same.
Answer:
if 8/10 radio wave mice were able to move the piece of wood, and 7/10 of non-radio wave mice were also able to move the piece of wood, then the radio waves have no effect upon the result.

an eclectic approach.
unconditional positive regard.
psychoanalysis.
Answer:
An eclectic approach
Explanation:
An eclectic approach is an approach that combines multiple different approaches. In psychotherapy, an eclectic approach can be described as one that relies on multiple theoretical orientations and techniques. This allows the therapist to be flexible and use methods that best suit their client's individual needs.
An eclectic approach combines concepts from different techniques, generally using one of them as a frame of reference.
An eclectic approach consists of using techniques of different orientations.
A common criterion in technical eclecticism is the level of efficacy demonstrated empirically.In this case, we seek to find the most appropriate treatments for each situation, according to scientific research.Therefore, we can conclude that an eclectic approach refers to a therapeutic approach that consists of using a variety of techniques and procedures regardless of theory.

Hi there!
Photosynthesis involves carbon dioxide (CO2) and water (H2O) as the reactants with glucose (C6H12O6) and oxygen (O2) as the products. We can write a basic chemical equation:
[tex]CO_{2} + H_{2} O - (light) -> C_{6} H_{12} O_{6} + O_{2}[/tex]
The equation has to be balanced, so the final equation for photosynthesis would be:
[tex]6CO_{2} + 6H_{2} O - (light) -> C_{6} H_{12} O_{6} + 6O_{2}[/tex]
The chemicals in correct order are:
[tex]CO_{2}\\H_{2}O\\ C_{6}H_{12}O_{6}\\ O_{2}[/tex]

Proteins whose conformations change when they are bound to an effector molecule are called
A. activator proteins.
B. regulatory proteins.
C. enzymes.
D. allosteric proteins
E. Inhibitory proteins
Answer:
Inhibitory proteins
Explanation:
Allosteric site = a binding site on the protein other than the active site
Allosteric effector molecules don't resemble the structure of the substrate. So, they cannot bind to the active site. Instead, they bind to an allosteric site and alter the conformation of the protein such that the activity of the protein is affected.
Allosteric effectors can be activators or inhibitors, i.e. the conformational change in the structure can activate or repress the protein function.
Allosteric proteins can also be regulatory proteins (Activators or inhibitors) or enzymes.
Which of the following is not a product of cellular respiration?
a. CO2
b. Energy
c. C6H1206
d. H20
Answer:
The only molecule in the group that is not a product of cellular respiration is C₆H₁₂O₆ (option c).
Explanation:
C₆H₁₂O₆ is the glucose molecule, which is an energetic substrate and not a product of cellular respiration.
Cellular respiration is the process by which, through the oxidation of glucose and in the presence of oxygen, energy is obtained in the form of ATP. The reaction that summarizes this process is:
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + Energy (ATP)↑
As can be seen in the diagram, while glucose and oxygen are substrates of the reaction, the resulting products are CO₂, H₂O and energy.

How was the earths biosphere affected during the Precambrian era
Answer:
Some three billion years ago, the Earth's atmosphere was virtually devoid of oxygen. At about 2.4 billion years ago, oxygen was released from the seas as a byproduct of photosynthesis by cyanobacteria. Levels of the gas gradually climbed, reaching about one percent around two billion years ago.

What is the resulting amino sequence if the following mRNA molecule undergoes translation 5’ AUG AGU CCU CUU UGA 3’ ?
Answer:
From the translation of the mRNA molecule 5’ AUG AGU CCU CUU UGA 3’ results the amino acid sequence Met-Ser-Pro-Stop, that is, Methionine-Serine-Proline and the last triplet being a stop codon.
Explanation:
Messenger RNA (mRNA) molecule is in charge of conducting the encoded genetic information to produce the protein synthesis, organized in a sequence of nucleotides called the genetic code. The arrangement of the nucleotides is in triplets of bases or codons, which encode the synthesis of an amino acid (translation), determine the beginning of the synthesis and also establish the stop.
In the given sequence, 5’-AUG-AGU-CCU-CUU-UGA-3’ results the amino acid sequence Met-Ser-Pro-Stop:
5'-AUG Methionine (Met), being at the same time an initiating codon.AGU Serine (Ser).CCU Proline (Pro).UGA-3' is a stop codon.Stop codons do not code for amino acids, but their presence in a codon sequence marks the completion of peptide or protein synthesis.
