Answer:
second trimester
Explanation:
The second trimester, which is week thirteen to week twenty four, the foetus would have develop enough to be picked up by the ultrasound scan. At this stage, the doctor can easily determine the sex of the foetus whether it is a boy or a girl.
The second trimester, which is week thirteen to week twenty four, the foetus would have develop enough to be picked up by the ultrasound scan. At this stage, the doctor can easily determine the sex of the foetus whether it is a boy or a girl.
What is Second Trimester?During this trimester, morning sickness typically subsides as well as the acute fatigue and breast discomfort. Your fetus has completed the development of all of its organs and systems and is about to start expanding in size.
For most women, the second trimester is the most physically satisfying. During this time, morning sickness typically subsides, and the intense fatigue and breast discomfort usually go away.
Human chorionic gonadotropin levels have decreased, and estrogen and progesterone levels have changed, which can be linked to these alterations.
Therefore, The second trimester, which is week thirteen to week twenty four, the fetus would have develop enough to be picked up by the ultrasound scan. At this stage, the doctor can easily determine the sex of the fetus whether it is a boy or a girl.

the potential for antibiotic resistance was recognized in the early 1940s, almost immediately after the first large-scale clinical use of penicillin, the first antibiotic. mass production of penicillin was part of the war effort of world war ii, when the drug was used widely by military populations to treat the wounded. however, even before the war had ended, resistance to penicillin was already being reported. in 1940, british biochemists sir ernst boris chain and sir edward penley abraham published a report about a bacterial enzyme capable of destroying penicillin. in the following decades, overuse and repeated exposure to antibiotic agents favored the selection and replication of numerous strains of antibiotic-resistant bacteria. select all of the statements that accurately portray the role of natural selection in antibiotic resistance. a) when bacteria are repeatedly exposed to antibiotics, they learn how to avoid the antibiotic and survive to reproduce. b) when people overuse antibiotics, the bacteria get resistant to the antibiotic and it is no longer an effective treatment. some bacteria possess a gene for bacterial resistance. these bacteria are likely to survive a course or antibiotics and reproduce. 09 d) bacteria containing the gene for antibiotic resistance can share a plasmid of the gene with other bacteria, allowing the population of bacteria with antibiotic resistance to survive and reproduce. when someone quits taking an antibiotic when they are feeling better, they likely kill only the weaker bacteria. the bacteria with a gene for antibiotic resistance survive, giving them the opportunity to reproduce. e
Answer: c,d,e
Explanation:
I did this and this is correct
Answer:
The following Statements accurately portrays role of natural selection in antibiotic resistance
c) some bacteria possess a gene for bacterial resistance. these bacteria are likely to survive a course or antibiotics and reproduce.
d) bacteria containing the gene for antibiotic resistance can share a plasmid of the gene with other bacteria, allowing the population of bacteria with antibiotic resistance to survive and reproduce
e) when someone quits taking an antibiotic when they are feeling better, they likely kill only the weaker bacteria. the bacteria with a gene for antibiotic resistance survive, giving them the opportunity to reproduce
Explanation:
When bacteria are initially exposed to an antibiotic, those most susceptible to the antibiotic will die quickly, leaving any surviving bacteria to pass on their resistant features to succeeding generations.
As in option C , bacteria possessing better gene will b selected by the nature and hence portrays Natural selection
In option d Bacteria reproduce by plasmid (extra chromosomal DNA ) transfer . Bacteria with antibiotic resistant gene with pass these genes to the succeeding generations.
When bacteria are initially exposed to an antibiotic, those most susceptible to the antibiotic will die quickly, leaving bacteria possessing gene resistant against antibiotics. Here, Darwin’s theory of natural selection comes in. This gives the bacteria an advantage over other(which do not possess antibiotic resistant gene) this bacteria will grow better than its neighbors and can increase in numbers
In option e When one quits antibiotics before completing the entire course of any prescribed antibiotic. The antibiotic resistant bacteria survives. Bacteria that are not controlled or killed by antibiotics. They are able to survive and even multiply in the presence of an antibiotic.

The photo shows a cross between a plant with white flowers and a plant with red flowers. The offspring is a plant with flowers that have both colors. X / Which pattern of inheritance is shown? 1/4 O A. Codominance B. Incomplete dominance O C. Recessiveness D. Multiple gene
Answer:
The correct answer is - A. codominance.
Explanation:
Codominance is an inheritance pattern that develops if there are two alleles of a particular gene in an organism and both are expressed together. It is not common as normally dominant allele masks the effect of recessive allele but here both traits occur.
Codominance is different from incomplete dominance as incomplete dominance expresses the dominant allele more than the recessive allele and expresses a mix of both.

The importance of the forest is that roots of the trees in forests reduce soil erosion, forests are a source of a great amount of biodiversity, and also trees in forests play an important role in the hydrologic cycle. Thus, the correct options are a, c, and d.
What is hydrologic cycle?The hydrologic cycle is the ongoing movement of water in the Earth-Atmosphere system. The water cycle is outlined as the movement of groundwater to the atmosphere and back again.
Since the vertical growing floor and resulting canopy shade create micro-niches by altering locally available light, heat, and moisture, forests have a high biodiversity.
The forest is important because the roots of trees in forests reduce soil erosion, forests provide a large amount of biodiversity, and trees in forests play an important role in the hydrologic cycle.
Thus, the correct options are a, c, and d.

Which step of protein synthesis does the lac operon stop and how ?
Answer:
Explanation:

The particle in the ice will have low energy and vibrate in a fixed position. The correct option is B.
What is freezing?The process by which something changes from liquid to solid as the temperature drops is known as freezing. Water basically freezes at 0 degrees Celsius.
The process of changing a substance from a liquid to a solid is known as freezing. When a liquid's molecules slow down enough, their attractions cause them to arrange themselves into fixed positions as a solid.
The average energy of the molecules in a liquid decreases as it cools. At some point, the amount of heat removed is great enough that the molecules' attractive forces draw them close together, and the liquid freezes to a solid.
The particles in a liquid eventually stop moving and settle into a stable arrangement, forming a solid.
Thus, the correct option is B.

Which statement regarding DNA packing in eukaryotes is false?
A Tight DNA packing tends to promote gene expression
B) Euchromatin can be highly expressed
с
none of the answers are false
D
A nucleosome consists of DNA wound around a core of 8 histone
molecules.
E Highly compacted chromatin is generally not expressed at all.
Answer:
The correct answer is - A. Tight DNA packing tends to promote gene expression.
Explanation:
Euchromatin which is less packed or condensed is highly expressed as it participates in the transcription whereas highly compacted chromatin - heterochromatin not expressed at all as these does undergoes the transcription process.
DNA binds around a core of 8 subunits of Histone protein in a nucleosome in which DNA is negatively charged and histone protein is positively charged protein .
DNA packing decreases its transcription and hence no expression.
In Drosophila, the linked mutations ebony body color (e), rough eyes (r), and brevis bristles (b), are autosomal recessive. A test cross yielded the following results:
wild type 169
ebony 619
ebony, rough 9
brevis 14
rough 93
ebony, brevis 97
rough, brevis 621
ebony, rough, brevis 165
Total 1787
1: Which locus is in somewhere between the other two?
a. ebony
b. rough
c. brevis
d. wild type
e. can not be determined from the information provided
2: What is the percentage of double cross overs?
Answer:
The correct answer is - 1) rough
2) [(9+14)/1786]* 100 = 1.2877 percentage
Explanation:
In this case there is mutated genes are :
mutated : ebony (e), rough (r) and brevis (b)
wild type: e+, r+ and b+
Given: wild type 169 (e+ r+ b+)
ebony 619 (e b+ r+)....... parent
rough, brevis 621 (e+ b r) .... parent
ebony, rough, brevis - 165 (e r b)
rough - 93 (e+ r b+)
ebony, brevis - 97 (e r+ b)
ebony, rough - 9 (e r b+) ....... double cross
brevis - 14 (e+ r+ b) ..... double cross
solution:
In this question, there is the three-point cross is performed, in such case, if one is mutated then the other two are normal. For instance, here ebony is mutated then the rest two are norma - e r+ b+.
We know the most frequent genotypes in such case, are parental and least frequent are double crossover genotypes. We can get the correct order of genes by the double-cross of parental genotypes and if we get double cross over then the gene order is correct.
(e b+ r+) -----------> (e r b+)
(e+ b r) ------------> (e+ r+ b)
double cross double crossover
between
parental gentype
Thus, the correct order is e r b that means rough is between ebony and brevis.
The percentage of double cross over =
(number of first double-cross + second double-cross over/1787)*100
[(9+14)/1786]* 100 = 1.2877 percentage
