Answer:
Option A, Substrate binding may induce a conformational change in the enzyme, which them brings catalytic groups into proper orientation.
Explanation:
Induced fit concept refers to introduction of continuous change of enzyme conformation on substrate binding. This change in the shape of enzyme either inhibit or enhance the activity of enzyme. This makes the enzyme catalytic and hence lower the activation energy thereby increasing rate of reaction.

You have a circular plasmid containing 9 kb of DNA, and you wish to map its EcoRI and BamHI sites. When you digest the plasmid with EcoRI and run the DNA on a gel, you observe a single band at 9 kb. You get the same result when you digest the DNA with BamHI. When you digest with a mixture of both enzymes, you observe two bands, one 6 kb and the other 3 kb in size. Explain these results. Draw a map of the restriction sites.
Answer:
A nick is created between G and A in GAATTC when using Eco R1 site while a nick is generated between G and G in GGATCC when Bam H1 is used. The difference in the nicks created is the main reason you observe two bands when you digest the circular plasmid with a mixture of both
Explanation:
Circular plasmid containing : 9 kb of DNA
Eco R1 and Bam H1 are known as restriction sites in DNA ( i.e. special sequences found in a DNA ) hence they can be specifically cleaved by the restriction enzymes enabling the insertion of a gene. that is why you will get a same result when you digest the Plasmid with either Eco R1 or Bam H1
but A nick is created between G and A in GAATTC when using Eco R1 site while a nick is generated between G and G in GGATCC when Bam H1 is used. The difference in the nicks created is the main reason you observe two bands when you digest the circular plasmid with a mixture of both

ability of a cell to form the whole organism
Answer:
Totipotency
Explanation:
Totipotency can be regarded as
capability of single cell to divide,develop as well as to form differentiated cells in a living body. This could be found in Meristematic plant cells since they posses the ability to develop into complete plants. Totipotent cells can be formed during sexual and asexual reproduction and these could include spores and zygotes. Some organism can experience totipotency in the sense that cells can dedifferentiate as well as regaining totipotency. Instance of this is plant cutting which used in growing an entire plant.

Describe at least two abiotic and two biotic factors found in this biome. (Desert Biome) How
do these abiotic factors interact with the biotic factors?
Abiotic: the sunlight and water.
Biotic: Plants and insects
Explanation:
Plants such as cactuses can absorb and conserve water in their roots and use the sunlight to grow taller
Insects such as Desert beetles can trap moisture in their thick exoskeletons so they are parched or burned by the sun. They sometimes bury themselves deep in the sand where it's cooler.
The abiotic factors in the desert help the biotic factors survive

Which of the following statements about cell respiration is true?
A In the electron transport chain, Oz is converted to CO2.
B Glycolysis splits sugar to produce pyruvate and FADH2-
C Electrons leave the electron transport chain in a molecule of water (H20).
D
Both B and C are correct.
The statement which is true about cell respiration is; Choice B: Glycolysis splits sugar to produce pyruvate and FADH2-
Definition of terms:
Cellular respiration is a process used by all living organisms to convert glucose into energy.
Cellular respiration is a collection of three unique metabolic pathways: glycolysis, pyruvate oxidation, the citric acid cycle, and the electron transport chain.
Glycolysis; This pathway is anaerobic and takes place in the cytoplasm of the cell. This pathway breaks down 1 glucose molecule and produces 2 pyruvate molecule. A process which releases FADH2- in the process.Pyruvate Oxidation: In eukaryotic cells, the mitochondria is the site of pyruvate oxidation. The release of CO2 is a characteristic of this step.The Electron transport chain: The electron transport chain is the final component of aerobic respiration and is the only portion of glucose metabolism that uses atmospheric oxygen.Electrons are rapidly transferred from one component to the next to the endpoint of the chain, where the electrons reduce molecular oxygen, O2 producing water in the process.

In the oceans on either side of the Isthmus of Panama are 30 species of snapping shrimp, 15 species on the Pacific side and 15 different species on the Atlantic side. Species live at different water depths. Morphological and genetic data show that Atlantic and Pacific species that live at similar depths are sister species. Geological evidence indicates that the Isthmus of Panama started rising about 10 million years ago and the oceans were completely separated by the isthmus about 3 million years ago. If the isthmus indeed formed gradually, which of the following patterns of genetic differences is most likely in these species pairs?
A) similar percentages of difference in DNA sequences between all pairs of sister species
B) greater percentage of difference in DNA sequences between sister species that inhabit deep water than between sister species that inhabit shallow water
C) greater percentage of difference in DNA sequences between sister species that inhabit shallow water than between sister species that inhabit deep water
D) greater percentage of difference in DNA sequences among Atlantic species than among Pacific species
Answer:
B) greater percentage of difference in DNA sequences between sister species that inhabit deep water than between sister species that inhabit shallow water
Explanation:
The isthmus formed gradually. About 10 million years ago, the isthmus began to separate the waters from the bottom, and snapping shrimp individuals inhabiting the deepness were separated for the first time. Since their separation, both groups evolved according to their new environment and the pressures acting on them. They started to gradually differentiate from each other, probably suffering many mutations through the years.
About 3 million years ago, the oceans were completely separated by the isthmus, meaning that those animals inhabiting the shallowest areas were the last ones to separate from each other on each side of the isthmus. Since then, they probably also suffered many mutations that drove them to differentiation.
However, as animals inhabiting the shallowest areas were the last ones to separate and, considering the time-lapse between both divergences, the highest degree of genetic difference is expressed by the sister groups inhabiting the deepest areas. Being separated from each other for a much longer time than shallow animals gave them more time to suffer more mutations and differentiate more.
The sister species at the depth of the ocean possesses a greater difference as compared to the sister species in shallow regions. Thus, option B is correct.
Evolution is the process of inheritable changes in the species with natural selection. The species in the close generation have a higher level of similarity in the traits.
What is the relation between the sister species?The sister species are the ones with the similarity in the traits. Thus, have the same ancestors and exhibit a greater percentage of trait similarity.
Atlantic and Pacific species are sister species and have similarities in the DNA sequence.
The isthmus separation is formed later in the ocean. The species present at the deeper range are older and are evolved. The species in the shallow region have less evolution as they are separated later.
Thus, the sister species at the depth of the ocean possesses a greater difference as compared to the sister species in shallow regions. Thus, option B is correct.

Answer:
Like chromosomes, genes also come in pairs. Each of your parents has two copies of each of their genes, and each parent passes along just one copy to make up the genes you have. Genes that are passed on to you determine many of your traits, such as your hair color and skin color.
