Describe the following methods of genetic engineering: gel electrophoresis,
Gel electrophoresis is a method of genetic analysis which involves seperating segments of DNA based on their size and charge.
It involves cutting DNA with various enzymes, then placing the DNA in an agarose gel. An electrical current is then run through the gel. Because DNA is a polar molecule the DNA segments will travel through the agarose cell as the current is applied. Larger fragments will travel shorter distances than shorter fragments. Two plates with 2 different DNA samples will be conducted and the orientation of the DNA strands will be used to make an analysis by comparing the 2 plates.

Q.2. Describe the different phases of meiotic prophase – I. Mention the chromosomal events during each stage.
Prophase-I occurs over a long duration and involves several complicated changes in meiotic cell division. It is important because genetic recombineiion and variation in sexually reproducing organism occurs due to the events of this phase.
EXPLANATION:❈ Leptotene —
➥ The chromatin network opens out and threads become clear.
➥ The chromosomes are thin, slender and long.
➥ Chromosome number is diploid.
❈ Zygotene —
➥ Corresponding chromosomes become intimately associated.
➥ The process of pairing is known as synapse. It is so exact that pairing is not merely between corresponding chromosomes but between corresponding individual units.
➥ The chromosomes become shorter and thicker.
❈ Pachytene or Pachynema —
➥ The synaptic chromosomes become very intimately associated.
➥ The pair of chromosomes becomes short and thick.
➥ Crossing over occurs at this stage. Chiasmata are clearly seen.
❈ Diplotene —
➥ Homologous chromosomes start separating from one another.
➥ Chiasmata tend to slip out of the chromosomes. This is known as terminalisation of chiasmata.
➥ Chromosomes start separating out but the separation is not complete.
➥ Nuclear membrane and nucleolus start disappearing.
❈ Diakinesis —
➥ The bivalents condense further and get randomly distributed.
➥ The separation of paired chromosomes is almost complete.
➥ Terminalisation of chiasmata is almost complete.
➥ Nuclear membrane and nucleolus disappear.

how do you know when a surface has produced more friction
Answer:
Rougher surfaces have more friction between them. Heavier objects also have more friction because they press together with greater force.
Hard Rough Surfaces and Plowing
More plowing will result in a higher the friction coefficient, uplow, and thus higher sliding friction force.
A sexually mature seahorse can produce thousands of offspring. What is the BEST reason overproduction of offspring by marine organisms is considered to be a reproductive advantage?
It increases competition.
It decreases competition.
It contributes to the organism’s biological success.
It causes stress on the environment which will apply stress to the creature to adapt.
Answer: D
Explanation:
There are large number of predators present in marine environment. Overproduction of offspring contributes the biological success of the organism.
What is overproduction?Overproduction is referred to the production of large number of species which can be physically supported by ecosystem.
Overproduction support survival of the fittest, by improving the genetic line.
Since the predators are more so, only that organism will survive who can adapt according to the that. This can contributes in organism's biological success.
Thus, the correct answer is C.

“Explain how chemical energy for use in the cell is generated by electron transport and chemiosmosis”
PLEASE HELP!!
*50 points to whoever can answer that question and draw a flowchart, thank you*
Answer: The ETC is the last part of cellular respiration. In the first steps of cellular respiration (glycolysis and Krebs cylce), electrons are freed from glucose derived molecules. In the ETC the electrons are passed on through a series of proteins in the inner membrane of the mitochondria. The electrons in a sense 'flow' to lower energy levels (see image), they lose energy in the process.
Energy produced by H+ travelling via ATP synthase and down a concentration gradient is used by chemiosmosis. ADP is phosphorylated with this energy to create ATP.
What is Chemiosmosis?Chemiosmosis is the passage of ions along their electrochemical gradient through a semipermeable transmembrane domain structure. Adenosine triphosphate is created when hydrogen ions pass a membrane during photosynthesis or cellular respiration. This is a significant example.
The process of ions (often H+ ions, commonly referred to as protons) diffusing across a membrane that is selectively permeable is known as chemiosmosis. Chemiosmosis produces a concentration gradient of a diffusing ion from across membrane, similar to osmosis. Potential energy that can perform work is present in concentration gradients.
Thus, energy produced by H+ travelling via ATP synthase and down a concentration gradient is used by chemiosmosis. ADP is phosphorylated with this energy to create ATP.

What type of reproduction involves forming offspring from two
parents?
a Asexual
b Sexual
C Mitosis
int?
d Replication
Answer:
Sexual
Explanation:
Sexual reproduction involves two parents and produces offspring that are genetically unique. During sexual reproduction, two haploid gametes join in the process of fertilization to produce a diploid zygote. Meiosis is the type of cell division that produces gametes.
Hope it helps
Answer: Sexual, I believe.
Explanation:
If it were Asexual, it'd only involve one parent. Mitosis has daughter cells have the same number of chromosomes as parent cells (heavy emphasis on cells as in plural cells.) And replication is just copying a cell.

Learning Competencies: 1. Explain how protein is made using information from DNA. 2. Explain how mutation may cause changes in the structure and function of a protein
Answer:
The correct answer is -
1. protein synthesis or central dogma
2. leads to changes in the structure by changing in the codes which results in a decrease or loss of function.
Explanation:
1, Protein is made from the information coded in DNA base sequences by the two process protein synthesis that is also called central dogma. The two-process involve in this are transcription involves encoding the information present in DNA by mRNA molecule that codes the information in complementary sequence to DNA. which is then moved out of the nucleus and perform the translation with help of tRNA and ribosome to code the amino acid with help of triplet codes present in mRNA. These amino acids chain are called proteins.
2. Mutations can lead to change in the base sequences or deletion of the base which affects the structure of the protein and also leads to changes in an encoded protein or to a decrease or complete loss in its function or expression. Mutation can damage the cell or organism as it affects the gene expression of all cells of organisms.

Decrease. Fewer energy storage molecules will be available to the fox population from the smaller rat population, so the fox population will reproduce less. This will lead to fewer births than deaths in the fox population.
Explanation:
In the trophic web occurs a process of energy transference through different organisms that places at different levels. Each level feeds on the preceding one and becomes food for the next one. The first link is an autotroph organism or producer. The following links are the consumers: herbivores are primary consumers and feed on producers. Carnivores are secondary consumers and feed on herbivores, and so on. The last links are the decomposers, microorganisms that act on dead animals degrading organic matter.
If any of the links change their population size (increasing it or decreasing it), it affects the superior links and the immediately anterior link.
Also, when two or more species are competing for the same source of food, a change in any of the population sizes will affect the other ones.
In the exposed example, foxes are affected by the increase in the opossum population size, that a direct competitor.
Both species, opossums and foxes, feed on the rats. As long as their population sizes remain stable, no species will be hardly affected by the other. However, when a change occurs, the size of any of the populations is altered, indefectibly affecting the other populations. In this example, the opossum population increased. The more opossums are in the region, the more they will prey on rats. Opossums will become stronger competitors to foxes, whose population remains the same. Rats´ population is also affected because they do not have enough time to reproduce at a higher rate recover. So we have
opossum reproducing at a higher rateopossum population increasingopossums strongly competing with foxesmore opossums feeding on more ratsrats not being able to reproduce at a necessary raterats decreasing in numberfoxes not having enough food (rats) to feed onfoxes survival and reproductive rates affectedfoxes death rate increasingfoxes population decreasing.As more opossums are feeding on more rats, and fewer rats are available for foxes, the fox population is affected. They do not have enough food to feed on and to survive. And they do not have enough energy to reproduce. So the survival and reproductive rates in the foxes population decrease. And as they do not have enough food, their death rate increases. Eventually, the fox population decreases in size.
