In transformation, a special sex pilus is required to connect two bacterial cells.
Answers
Answer:
In binary fission, the two new cells that are formed are susceptible to the same antibiotic.
Explanation:
Binary fission is the most common type of asexual reproduction in bacteria. Binary fission involves the duplication of the genetic information (i.e., bacterial DNA) and the subsequent separation into two cells during cytokinesis. It is a type of prokaryotic asexual reproduction where replication and segregation are simultaneous processes. Binary fission does not involve the incorporation of new genetic material, thereby the resulting daughter cells will inherit the same genetic information of the parental bacterium, being in this case susceptible to the same antibiotic.

A the top answer is correct on ENG 2022
Explanation:
Select the statements that explain why duplication is a driving force for evolution and the generation of new genes.
a. Genes duplicate and then diverge from the original sequence to create multigene families.
b. Duplication of a chromosomal region always results in novel gene functions.
c. Changes in gene function can occur when random fixed mutations are introduced into a new chromosomal environment.
d. Duplicated genes provide extra copies of DNA that are not constrained by an essential function.
Answers
Answer:
The correct statements are - a, c, and d.
Explanation:
Gene duplication delivers new genes and families of genes due to some arbitrary changes over some undefined time frame.gene duplication at various locations can create new genes with either advantageous or unsafe impacts. Arbitrary changes can prompt an additional duplicate of DNA bringing about dosage compensation where the deciding mutations can be lost.
Gene and genome duplications give a source of hereditary material for mutation, float, and selection to work on, making new evolutionary opportunities conceivable. Accordingly, many have contended that genome duplication is a prevailing element in the development of the evolution of complexity and diversity.
Thus, the correct answer is - a, c, and d.

b. increased use of personal vehicles, telephones, and computers.
c. increased number of meals eaten outside the home
Answers
Answer:
c. increased number of meals eaten outside the home
Explanation:
Environment is the surrounding of living organism, where he gets to survive by meeting its needs.
Environmental factors are factors in the environment that are associated to growth and development example is temperature.
The environment an individual stays have a great influence on the physical expression and character of the individual.
For a fat person the environment had played out his role which should be controlled to achieve a significant weight loss. Increasing number of meals eaten outside the house is one major factor that would not allow such individual to loose weight. Intake of food should be greatly controlled and watched to achieve weight loss.
In Lake Victoria (the largest freshwater lake in Africa), researchers recently found that in one cichlid species, male fishes with brighter red coloration maintain large territories. Red males are at an advantage because female cichlids tend to choose males with brighter color and larger territory size. Assuming that red coloration is heritable, what do you expect would occur if some females of this species began to prefer male cichlids with blue coloration?
Answers
Answer:
The population of cichlids with blue coloration increases.
Explanation:
If the female prefers blue colored cichlids, so they mate with each other and increase occurs in the population of blue colored cichlids and with the passage of time bright colored cichlids decrease in number due to less reproduction with female cichlids. So those cichlids becomes dominant in the lake to which more female mate and those which receive less female are less in number and having lower territory size.
Cichlid is the fish variety found diversely in South America and Africa. They are primarily herbivores and feed on plants and algae. Cichlids mate both with single or multiple partners.
Speciation would occur if some females of this variety began to prefer male cichlids with a blue coloration. The population of blue colored fishes will increase.
The explanation for the answer is:
Female mate choice plays a major role in speciation. They play important role in differentiation and speciation.After several generations of mating with the blue parent, all the offspring will become blue.Change in the recurrence of variation or the genetic drift where red-coloured fishes are preferred will result in the fixation.This female choice would act as a barrier to the gene flow.The mutation rate in genes coding for the colour will increase.

) Recall what you know about crossing over, independent assortment, and random joining of sex cells during sexual reproduction.
Answers
Answer:
Crossing over is the process of interchange of genetic information among non-sister chromatids of homologous chromosome pairs during meiosis (specifically during synapsis in prophase I). During this process, the synaptonemal complex enables the interchange of chromosome fragments between non-sister chromatids through crossing over. Moreover, in sexual reproduction, the zygote diploid cell can be generated by the random joining of fully differentiated haploid gametic cells (male and female gametes). The combination of random joining with the phenomenon of crossing over is known to considerably increase the genetic variation of the resulting offspring. After zygote formation, the successive cycles of cell divisions during embryonic development will develop an organism that during its adult stage will reproduce via sexual reproduction.

a. three embryonic germ layer
b. pseudocoelom
c. bilateral symmetry
d. protosome development
e. true tissues
Answers
Answer:
b. pseudocoelom
Explanation:
A pseudocoelom is a false body cavity of some invertebrates which occupies the space localized between the mesoderm and the endoderm of the gut. This false cavity is found in nematodes.
Arthropods exhibit:
1- Bilateral symmetry because both opposite sides of the body are similar,
2- they are protostomes because the blastopore becomes the mouth during embryonic development,
3- they have true tissues because tissues are formed by groups of cells which share a common function, and finally,
4-arthropods are triploblastic because they are formed by three germ embryonic layers (endoderm, mesoderm and ectoderm).

If a small drop of tiny particles such as pollen grains are dropped into a drop of water on a microscope slide, they will appear to vibrate and spread out. The primary reason for this is
Answers
Answer:
The primary reason is that the pollen grains are being struck by water molecules that move in different directions. These strikes fluctuate and sometimes are uneven.
Explanation:
This vibration and spread out of molecules in water is called Brownian Motion. It is the result of the collision of small particles of water with big particles of pollen. As the particles of water move randomly hitting different sides of the pollen particle, at times, there will not be a coordinated movement, but as the movement of water particles is random, there will be moments when one side of the pollen particle will collide with more water particles, when this happens there is an unbalanced force that makes the pollen particle moves in a direction.

a) List three examples of ruminant livestock. b) Describe how ruminant cattle digest food? c) Why do cattle produce more methane than other types of animals?
Answers
Answer:
a)Ruminants include cattle, sheep, goats, buffalo, deer, elk, giraffes and camels. These animals all have a digestive system that is uniquely different from our own. Instead of one compartment to the stomach they have four. Of the four compartments the rumen is the largest section and the main digestive centre.
b)Digestion in ruminants occurs sequentially in a four-chambered stomach. ... The mass is finally passed to the true stomach, the Abomassum, where the digestive enzyme lysozyme breaks down the bacteria so as to release nutrients.
c)The difficult-to-digest grass ferments in the cows' stomachs, where it interacts with microbes and produces gas. Thus,cattle produce more methane than other types of animals.

In his deletion mapping experiments, Benzer coinfected bacteria with one phage that contained a point mutation and one phage that contained a deletion mutation. Assume that the point mutation and deletion mutation are not in overlapping regions of the phage genome. What phage recombinants would you expect if a crossing-over event occurred between the regions of the two mutations?
Answers
Answer:
The correct answer would be - there will be wild type and double mutant (contains both the deletion mutation and the point mutation)
Explanation:
It is mention that the deletion mutation and point mutation are non-overlapping or no overlapping regions in the phage genome. A crossing-over event between the regions of these two mutations would get wild-type which means there would be neither point mutation nor deletion mutation and other would be a double mutant that contains both mutation - the point mutation and the deletion mutation.
Thus, the correct answer is - there will be wild type and double mutant (contains both the deletion mutation and the point mutation)

D. Chitin is a heteropolymer, whereas starch, cellulose, and glycogen are homopolymers.
Answers
Answer:
Option A
Explanation:
All four types of polysaccharides are homopolymers ie they are made up of repeating units of only one type of monomers.
Starch, glycogen and cellulose are made up of repeating monomeric units of glucose with the number of glucose units and the different linkage types different these molecules. E.g the linkage between glucose units in glycogen is alpha 1-4 linkages and in cellulose, we have glucose in beta 1-4 linkages.
In chitin, a derivative of glucose is present in repeating units, here, we have N-acetyl-D-glucosamine in beta 1-4 linkages.

The correct answer is D) The codon AUG must be identified.
What must occur for protein translation to begin is that the codon AUG must be identified.
The process starts when the 5AUG or start codon is identified. In the polypeptide chain, the 5AUG is the first amino acid. We are talking about Transition, the process when the genetic code in an RNA molecule has to be decoded in a polypeptide chain in order to deliver an amino acid sequence. In this complex transition system, there are important components included such as ribosomes, transfer RNA, and mRNA.

HELP!! PLS O.o Looking at the heat circulation in the ocean, what might happen to it if large amounts of cold water are added in the Polar Regions as glaciers melt? (3 points) Based on your response above, what effect could this have on the climate in your area?
Answers
Answer:
The warm upper waters towards the poles from the tropic is done by surface circulation. If large amounts of cold water are added in the Polar regions as glaciers melt then the hot water cannot flow to the poles, the cold water will make the water very dense, which won’t allow warm upper waters to flow.
The effect it would have in the climate of my area is that it will increase the temperature of the local areas because of the rise in temperature of the surface ocean water.
