Answer: B heterotrophs
Explanation: animal-like protists (known as protozoans, or 'first animals') share heterotrophic behaviors, meaning they acquire their nutrients by exhibiting a very animal-like hunting behavior and consume bacteria or other smaller protists.

Which student will most likely overcome their nerves?
A.one who thinks positively and practices the speech in advance
B.one who thinks positively and stays up late to practice the speech
C.one who gets plenty of rest and eats sugary foods for energy
D.one who gets plenty of rest and avoids practicing the speech
Answer:
A.one who thinks positively and practices the speech in advance
Explanation:
It makes more sense
Student will overcome their nerves who thinks positively and practices the speech in advance
Positive behaviourThe person who thinks positively and practices the speech in advance will most likely overcome their nerves because the positive behaviour has good effect on the personality of an individual. Those people who think negative, they will not get success in their life.
Practice's benefitsThere is a saying that practice makes a man perfect. That person who regularly practice a specific topic, they can do the speech very well or other things in their life so we can conclude that student will overcome their nerves who thinks positively and practices the speech in advance.

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.

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.
Human cells have 46 chromosomes. Each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere.

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.

What is the relationship between boiling point and pressure?
The boiling point of a liquid is the temperature at which its vapor pressure is equal to the pressure of the gas above it. The normal boiling point of a liquid is the temperature at which its vapor pressure is equal to one atmosphere. Microscopic view inside a bubble in boiling water.
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.
