two similarities between mesozic and Cenozoic era on the basis of evolution
Answer:
Similarities between mesozoic era and cenozoic era are defined below :
- Mesozoic era and Cenozoic era both started to evolve right after the mass extinct according to the sources of evolution.
- Mass extinction is stated as (K-extinction) and many of the major life forms evolved during these two eras.
- Fossils of birds and reptiles were found in Mesozoic era and Fossils of mammals were found in the Cenozoic era.

What happens to the amount of energy as it moves up through an energy pyramid?
A. Some of the energy is lost.
B. Organisms double their energy as they move up the pyramid
C. Energy is transferred from the top to the bottom
D. The energy levels stay the same
Answer: some energy is lost from the pyramid, energy is transferred from bottom (producers) to top, but in decreasing amounts.
Explanation: total energy is conserved, but not necessarily within the energy pyramid, which is an open system where energy is lost from the pyramid, mainly as heat but also as sound.
Energy is transferred up the pyramid but the amount transferred at each stage is less because of losses outside the pyramid.

October 1, 2017 marks 27 years since the beginning of the Human Genome
Project. The goal of the group was to map the entire 3 billions bases and
80,000 genes in the human genome. On April 14, 2003, it was announced
that the goal was accomplished. Using this information, scientists have been
able to predict the risk of genetic diseases and understand the process of
inheritance. Which of the following statements best describes the process of
using the genetic code to produce polypeptides (proteins)?
Translation is used to produce a strand of RNA and proteins from a single strand of DNA.
O RNA produces a strand of DNA through transcription, then the DNA builds a protein molecule
through translation
O A single strand of DNA is used to make mRNA using translation, then the mRNA provides the
template for producing a protein through transcription
O A single strand of DNA is used to produce mRNA through transcription, then translation provides
the code for bonding amino acids to make a protein.
Answer:
The last one. A single strand of DNA is used to produce mRNA through transcription, then translation provides the code for bonding amino acids to make a protein.
Explanation:
Educated guess, but also. Translation is the process by which mRNA is decoded and translated to produce a polypeptide sequence, otherwise known as a protein. This method of synthesizing proteins is directed by the mRNA and accomplished with the help of a ribosome, a large complex of ribosomal RNAs (rRNAs) and proteins.

Explain the basis for the great diversity of proteins in living organism.
Answer:
Explanation:
Protein functions are so diverse because of the many unique three-dimensional structures protein polymers form. Despite such variety, proteins also share several specific structural characteristics in their monomers, the amino acids. Structural similarities among amino acids make protein synthesis a uniform and regulated process; however, each amino acid contains a unique structural component as well. Specific differences between each amino acid interact to create unique three-dimensional protein structures. Combined, the similarities and differences between amino acids explain how cells can build a diverse pool of proteins from the same set of building blocks. Protein synthesis involves building a polymer of amino acids with complex three-dimensional structure. Dehydration synthesis forms a peptide bond between amino acids and releases a water molecule.

Explanation:
True or false Solutions of equal solute concentration are isotonic.
Answer:
Explanation:
now you have two mixtures of different solute concentrations. In comparing two solutions of unequal solute concentration, the solution with the higher solute concentration is hypertonic, and the solution with the lower solute concentration is hypotonic. Solutions of equal solute concentration are isotonic.
How are living things put together?
Answer:
All living things are made of cells; the cell itself is the smallest fundamental unit of structure and function in living organisms. In larger organisms, cells combine to make tissues, which are groups of similar cells carrying out similar or related functions.
Explanation:
The cell cycle has a regular system of checks and balances that prevents damaged or mutated cells from proceeding to the next phase. One way an organism deals with the problems is to kill the damaged cell before it passes on the problem to its daughter cells. This is a normal process called apoptosis.
a. True
b. Fale
Answer:
A. True
Explanation:
Apoptosis is a normal cellular process in which the cell inherently programs the death of a mutated or damaged cell without affecting the healthy condition of the other surrounding cells by proliferating.
Apoptosis is a system of checks and balances that the cell uses to prevent damaged or mutated cells from proceeding to the next phase in the cell cycle. This curbs or prevent the damaged cell from passing on the problem to its daughter cells. Hence, according to this question, it is TRUE.

1. Which of the following is an example of a mutation?
ANSWER: a. A red blood cell loses its nucleus
b. A zygote receives two X chromosomes
c. A strand of mRNA is produced from DNA
d. A nucleotide is missing in a replicated DNA
Answer:
A
Explanation:
Quite simple actually. When a blood cell loses its nucleus it has no type of genetic code in order for it to function. With no DNA or Nucleus, the organelles inside the cell serve no purpose. This causes the cell to either swole or shrink. This is a form of mutation. This happens when there is no activity in the cell and it loses its proteins in the cell membrane, which leads the cell to use passive homeostasis more often than active. With no genetic code for it's cell transport, the cell gives out more necessary molecules, or takes in more necessary molecules.
If a nucleotide is missing in a replicated DNA, it would lead to a change in the gene expression which would lead to mutation. The correct answer is option d.
An alteration in the DNA sequence is known as a mutation, which can happen spontaneously or as a result of toxins or radiation. An organism may experience no effect, negative consequences, or positive effects as a result of a mutation.
Option d here refers to a mutation in which a nucleotide is absent from a DNA molecule that has been duplicated. The building components of DNA are called nucleotides, and if one is absent, the genetic code can be changed. This alteration in the DNA sequence may have serious repercussions, including the development of hereditary illnesses or disorders.
Therefore, a nucleotide is missing in a replicated DNA is an example of mutation i.e. Option D.

What happens during Prophase I? You will need to think about what you learned during mitosis to fully answer the question.
DNA coils into chromosomes
Crossing over
Nuclear Membrane disappears
Chromosomes line up in the middle of the cell
Answer:
Crossing over
Explanation:
Prophase I is the first stage of meiosis I, it is the longest phase of meiosis. Crossing over (also known as recombination) can be defined as the process of exchange of genetic material between non-sister chromatids that occurs during Prophase I. Crossing over represents a critical source of genetic variation in offspring (the other one is the random orientation of the homologous chromosomes pairs). After crossing over, the resulting haploid (n) gametes aren't genetically identical to one another.
