Answer:
The correct answer is - would be double which is 1472 mm Hg.
Explanation:
According to Boyle's law that says the relationship between volume and pressure of a gas at constant pressure shows an inverse relationship which means if volume will increase then pressure will be decrease and vice versa.
P1V1 = P2V2 .........Boyle's law
Given: P1 = 736 mm Hg
V1 = 50 mL
P2 = ?
V2 = 25 mL
Solution:
from the Boyle's law
(P1V1)/V2 = P2
736×50/25 = P2
P2 = 1472
So the decreasing the volume to half increases the pressure double. It proves it follows Boyle's law

Okay, so the female's eyes will be Xx because she carries it and I am not sure if the male is a carrier as well or not so if he is it will be Xx on the top and Xx on the side of the male is not then it will be XX and Xx and it does not matter which is on top which is on the bottom. If the male is a carrier then the outcomes will be XX, Xx, Xx, xx so they will have a 1:4 chance of getting white eyes if the male is NOT a carrier then it will be XX+Xx = XX, XX, Xx, Xx with no chances of having white eyes
5. What does EGS stand for in geothermal energy?
A) Engraved Geothermal System
B) Enhanced Geothermal System
C) Exhaust Gas System
D) Engineered Geophysical System
(EGS) stands Enhanced Geothermal Systems which can greatly increase geothermal energy utilization. Therefore, option (B) is correct.
What is EGS?Enhanced Geothermal Systems (EGS), which are also referred to as engineered geothermal systems on occasion, present a significant opportunity for significantly broadening the application of geothermal energy.
In an EGS, fluid is injected into the subsurface under conditions that are carefully regulated. This causes previously closed cracks to reopen, which in turn creates permeability in the rock. The increased permeability of the rock makes it possible for fluid to move freely within the newly fractured rock and for heat to be transported to the surface, where it can be used to create electricity.

Compare and contrast autotrophs and heterotrophs
Answer:
Autotrophs are organisms that can produce their own food from the substances available in their surroundings using light (photosynthesis) or chemical energy (chemosynthesis). Heterotrophs cannot synthesize their own food and rely on other organisms — both plants and animals — for nutrition.
autotrophs are known are known as producers because they are able to make their own food from raw materials and energy, such as plants, algae and some types of bacteria.
heterotrophs are known as consumers Because they consume producers or other consumers such as dogs, birds, fish and humans.

C) They have variations in the primary DNA but have the same set of plasmids.
D) They have the same primary DNA and the same set of plasmids.
Answer:
A
Explanation:
They have the same primary DNA but may have different plasmids.
The two daughter cells which are formed after the binary fission of a bacterial cell have the same primary DNA but may have a different set of plasmids. Thus, the correct option is B.
What is Binary fission?Binary fission is a type of asexual reproduction where a cell body is separated into two different bodies.
During binary fission, the genetic material of an organism is duplicated in the parent cell which enables the two new organisms formed to be able to contain the separate copy of DNA in their nucleus.
In a bacterium cell, when the two daughter cells are formed after the process of binary fission, they contain the same primary DNA but have different plasmids.
Therefore, the correct option is B.

In the logistic growth model, as a population approaches the carrying capacity, what happens to its growth rate?
A
becomes exponential
B
doubles
C
increases
D
slows to zero
In the logistic growth model, as a population approaches the carrying capacity, the growth rate of the population will slow down to zero. Thus, the correct option is D.
What is Logistic growth model?The logistic growth model is a parameter which represents the rate at which the population would grow if it were unencumbered by the environmental degradation. A second parameter, that is K, represents the carrying capacity of the system of species which are being studied.
In logistic growth, a population's per capita growth rate gets smaller and smaller as the population size when it approaches a maximum imposed by the limited resources in the environment, known as the carrying capacity (K). Exponential growth model produces a J-shaped curve, while logistic growth produces an S-shaped curve.
Therefore, the correct option is D.

Describe DNA synthesis in detail
Answer:
DNA synthesis is the biological process by which a deoxyribonucleic acid (DNA) molecule is created. In the cell, each of the two strands of the DNA molecule acts as a template for the synthesis of a complementary strand.
Answer:
The discovery of the double-helical nature of DNA by Watson & Crick explained how genetic information could be duplicated and passed on to succeeding generations. The strands of the double helix can separate and serve as templates for the synthesis of daughter strands. In conservative replication the two daughter strands would go to one daughter cell and the two parental strands would go to the other daughter cell. In semiconservative replication one parental and one daughter strand would go to each of the daughter cells.
Through experimentation it was determined that DNA replicates via a semiconservative mechanism. There are three possible mechanisms that can explain DNA's semiconservative replication.
(a) DNA synthesis starts at a specific place on a chromosome called an origin. In the first mechanism one daughter strand is initiated at an origin on one parental strand and the second is initiated at another origin on the opposite parental strand. Thus only one strand grows from each origin. Some viruses use this type of mechanism.
(b) In the second mechanism replication of both strands is initiated at one origin. The site at which the two strands are replicated is called the replication fork. Since the fork moves in one direction from the origin this type of replication is called unidirectional. Some types of bacteria use this type of mechanism.
(c) In the third mechanism two replication forks are initiated at the origin and as synthesis proceeds the two forks migrate away from one another. This type of replication is called bi-directional. Most organisms, including mammals, use bi-directional replication.

The TAS2R38 gene encodes a receptor protein that influences the ability to taste bitterness. The gene has two alleles: a dominant, wild-type allele that enables an individual (taster) to taste bitterness and a recessive, mutant allele that interferes with the ability of an individual (nontaster) to taste bitterness. In a sample of 2,400 people, 1,482 were found to have the dominant (taster) phenotype. Assuming that the population is in Hardy-Weinberg equilibrium, approximately how many individuals in the sample are expected to be heterozygous for TAS2R38
Answer:
The correct answer is - 1133.
Explanation:
According to H-W equilibrium;
p2 +2pq + q2 = 1 ........... eq.1 and
(p+q)2 = 1 ..............eq.2
Here q = frequency of the recessive allele,
and p = frequency of the dominant allele in the population
The genotype of p2 + 2pq shows the dominant(taster) phenotype.
The genotype of q2 shows the recessive(non-taster) phenotype.
q^2 = (2400 - 1482)/2400
= 0.3825
= 0.618
using eq. 2 we get p= 1-q
=0.382
2pq = No. of heterozygotes/2400
No. of heterozygotes = 1133.1648

g It was noted in the Experimental Pathways feature in Section 10.4 that at least two- thirds of the human genome is derived from transposable elements. The actual number could be much higher, but it is impossible to make a determination about the origin of many other sequences. Why do you suppose it is difficult to make assignments about the origin of many of the sequences in the human genome
Answer:
TEs are repetitive and mobile elements, thereby it is hard to trace their origins
Explanation:
Repetitive elements are patterns of nucleotide sequences in the DNA characterized to have multiple copies throughout the genome. DNA mini-satellite and Transposable Elements (TEs) are some examples of highly repetitive DNA. TEs are repetitive mobile elements that have the ability to jump within the genome and occupy a major part of eukaryotic genomes. For instance, there is a type of TEs called retrotransposons which mobilize through a copy-and-paste mechanism, thus increasing their number in a genome. In consequence, TEs represent highly repetitive and dynamic genomic sequences, and thereby it is hard to trace their evolutionary histories.
The stages of mitosis were originally defined by cellular features observable through a light microscope.
a. True
b. False
Answer: TRUE
Explanation:
The cell division that takes place during the growth and development of an organism is in an as MITOSIS. Mitosis takes place in somatic cells that is, body cells that are not involved in the production of gametes. The difference stages of mitosis were originally defined by cellular features observable through a LIGHT MICROSCOPE. These stages includes:
--> PROPHASE: when viewed under a light microscope, each chromosome shortens and thickens and is seen to consist of two chromatids. The Centriole begin to separate.
--> METAPHASE: The nuclear membrane disappears, a spindle forms, the chromosomes line up across the middle of the cell and become attached to the spindle fibres at their centromeres.
--> ANAPHASE: The sister chromatids are pulled apart to opposite ends of cell as the spindle fibres contract.
--> TELOPHASE: A nuclear membrane forms around each set of chromatids, and the cell divides into two daughter cells.
