Answer:
B. Proteins complexed with DNA to form nucleosomes- Histones
I. Used in chain terminator procedure to stop chain elongation- ddNTPs
H. Separation of DNA fragments based on polyanionic nature- Gel electrophoresis
F. Substrates for translation- mRNA
J. A DNA gel for sequencing shows the base sequence of GATCGGA reading from bottom to top. The template sequence can be determined using this information 5' - TCCGATC
Explanation:
1. The DNA in the chromatin is packaged and ordered into structural units known as nucleosomes by theirformation of complexes with proteins called Histones. Histones are small basic proteins rich in the amino acids arginine and lysine.
2. In the chain termination procedure of DNA sequencing, chain elongation is terminated at several points whenever the dideoxynucleotides, ddNTPs are added to the growing sequence of the newly synthesized DNA strand. Because the ddNTPs lack an OH group and 3' position, new nucleotides cannot be added.
3. Gel electrophoresis is a separation technique used to separate DNA fragments based on ability to migrate an electric field. The DNA molecules are negatively-charged (polyanionic) and are separated based on their size with smaller molecules migrating fastest than bigger ones.
4. The messenger RNA, is synthesized from the part of the DNA coding for a functional protein. They serve as the template from which the ribosomes read to make proteins. Thus, they serve as the substrates for translation.
5. The reading of the base sequence from an autoradiogram (DNA gel for sequencing) is from top to bottom in the 5' to 3' direction. Since the template is complementary to it, it will read in the 3' to 5' direction CTAGCCT or TCCGATC in the 5' to 3' direction.

• How does precipitation affect the topology of the earth?
Answer: Global Climate Change. comes from precipitation. Too little precipitation can result in dry soil, shallow streams, and shortages of municipal water supplies. However, too much precipitation can also have a negative impact on human activities, business and industry, agriculture, and the environment. As moist air is forced up the windward slope it expands and cools, eventually causing water droplets to condense when the air is saturated. These droplets form clouds and grow to produce rain or snow that typically falls out on the windward side of the range. ... As air approaches the topography, it slows down.
Explanation:
Precipitation affects the topology of the earth positively and negatively ( excess precipitation leads to soil erosion while moderate precipitation repairs broken/dry soil surfaces making it fertile )
Precipitation has a positive and negative effect on the topology of the earth because excessive precipitation like heavy rainfall causes flooding and the heavy movement of flood water, washes away the surface soil ( erosion ) which affects the topology of the earth negatively. while
Moderate precipitation repairs dry and broken soil surfaces making the topology of the earth fertile, supporting the growth of plants and inhabitation of animals .
Hence we can conclude that precipitation affects the topology of the earth positively and negatively.

A.O. is an 89-year-old woman with a long history of systolic heart failure secondary to a large left ventricular infarct when she was in her 70s. She had poor activity tolerance and required assistance with activities of daily living. Even minimal activity was associated with moderately severe dyspnea and exertional chest pain, which was relieved by rest. A.O. also exhibited marked pedal edema bilaterally. She is being treated with digitalis, furosemide (Lasix), KCl, and sublingual nitroglycerin.
What compensatory mechanisms are likely to be operative in A.O. to enhance cardiac output?
A. Prolonged stretch on the myocardium results in myocardial atrophy.
B. Baroreceptors detect low blood pressure and cardiac output and activate the parasympathetic system resulting in increased heart rate.
C. Renin-angiotensin system activation causes decreased glomerular filtration rate and fluid retention, which results in increased preload.
D. Baroreceptors detect low blood pressure and cardiac output and activate the sympathetic system resulting in decreased heart rate.
Answer:
The correct answer is ''C. Renin-angiotensin system activation causes decreased glomerular filtration rate and fluid retention, which results in increased preload.''
Explanation:
In states of low cardiac output, the renin-angiotensin-aldosterone pathway is activated as a compensatory mechanism, whose objective is to fundamentally modify the peripheral circulation, which operates in conjunction with the activation of the medullary neuro-adrenal system, to maintain blood pressure. These two mechanisms, which are totally different, are closely linked; thus, stimulation of beta-1 adrenoreceptors in the juxtaglomerular apparatus, as a consequence of a high adrenergic output, causes renin output in heart failure. On the other hand, the activation of baroreceptors in the renal vascular bed caused by a reduction in renal blood flow, is also responsible for the release of renin, it occurs in patients with severe heart failure managed with diuretics and salt restriction.

Explanation:
Energy pyramid accurately represents the amount of energy at each level of this food web Owls.
What is Energy pyramid?
The energy present within the trophic layers of an ecosystem is called an energy pyramid, sometimes referred to as a trophic or ecological pyramid.
The producers are located in the base of the pyramid, which is also its greatest level. The amount of energy diminishes and the levels get smaller as you progress up the pyramid, via the trophic levels to primary, secondary, and tertiary consumers.
Even though it cannot be produced or destroyed, energy is emitted as heat at each level. Only 10% of energy is essentially transferred from one level to the next.
Therefore, Energy pyramid accurately represents the amount of energy at each level of this food web Owls.

Bacterial DNA is a double-stranded helix that has to ___________ its strands during replication. The _______ of DNA strands at the replication fork creates twists farther down the helix that need to be ______ by DNA _______. Ciprofloxacin ______ this enzyme to block DNA synthesis and stop the deadly bacteria from growing.
Answer:
Bacterial DNA is a double-stranded helix that has to separate its strands during replication. The unwinding of DNA strands at the replication fork creates twists farther down the helix that need to be relaxed by DNA gyrase. Ciprofloxacin inhibits this enzyme to block DNA synthesis and stop the deadly bacteria from growing.
Explanation:
DNA which stands for deoxyribonucleic acid is the molecules that stores genetic information in most living organisms. For successive reproduction to take place as well as growth to occurs in organisms, the genetic information stored in the DNA must be copied into new cells. This is achieved through the process of DNA replication.
DNA is a double-stranded molecule that is helical in shape. For replication to occur, the double strands has to be separated so that the information stored within can be accessed and then copied. DNA helicases are enzymes which are essential during DNA replication because they separate double-stranded DNA into single strands allowing each strand to be copied. The unwinding of DNA strands at the replication fork creates twists farther down the helix that need to be relaxed otherwise, the DNA strands will break. The enzyme responsible for relaxation these twists is known as DNA gyrase. Thus, any drug like Ciprofloxacin than inhibits DNA gyrase will block the DNA replication process in bacteria thereby stopping the growth of the bacteria.

Tumor suppressor proteins can assist in slowing down the cell cycle under appropriate conditions.
a. True
b. False
Answer:
True
Explanation:
Tumour-suppressor proteins can be regarded protein that it's action
alleviate the potential for cancer as well as tumor formation, through modulation of cell growth by negative regulation of the cell cycle or through promotion of apoptosis. Mutation dysregulation of tumour-suppressor proteins could result to unregulated growth of cell as well as tumour development. In humans, tumor suppressor which is known as p53 is been encoded by TP53 gene. Some of the mutations that is seen in TP53 gene has mutant form of p53 as result, and there won't be room for longer function in slowing down cell cycle, and this will result in the cell becoming cancerous. Though some mutant forms of p53 has the ability to have increased resistance of cell to anticancer treatments. This is known as gain-of-function mutation.
Therefore, Tumor suppressor proteins can assist in slowing down the cell cycle under appropriate conditions

a. The distribution of the RNA-binding transcription factor called bicoid and the protein nanos localized in the anterior and posterior poles of the embryo, respectively
b. The distribution of a gene that codes for an RNA-binding protein called nanos localized in the anterior pole of the embryo and a transcription factor called bicoid localized in the posterior pole of the embryo
c. The distribution of a gene that codes for an RNA-binding protein called nanos localized in the posterior pole of the embryo and a transcription factor called bicoid localized in the anteror pole of the embryo
d. The distribution of the RNA-binding transcription factor called bicoid and the protein nanos localized in the posterior and anterior poles of the embryo, respectively
Answer:
c. The distribution of a gene that codes for an RNA-binding protein called nanos localized in the posterior pole of the embryo and a transcription factor called bicoid localized in the anterior pole of the embryo
Explanation:
When the Drosophila zygote develops, it goes through different stages until it gets to the blastula stage. At this point, there are pole cells that determine the axis of the organism -the anteroposterior and the dorsoventral axis-.
A two hours old embryo has already determined its two axes. A ten hours old embryo has already determined its body segments. And from there, each of them develops a structure that turns to be their identity.
Different genes determine the polarity of the egg.
Dorsoventral genes place in the superior and inferior parts of the egg and determine the development of dorsal and ventral tissues.
The same happens with anteroposterior genes.
The BICOID genes place in the anterior part of the egg and activate the hunchback genes that determine the development of the head and the thorax. The Bicoid mRNA distributes in the anterior region of the egg.The NANOS gene reprimes the hunchback genes, which promoted the development of the posterior structures of the body. The Nano mRNA places in the posterior region of the egg, and Nano proteins distribute in this area.The polarity genes of the egg are genes of maternal effects.
While the bicoid and nano genes are expressed in the ovary, the hunchback gene is expressed in the embryo. This last one is activated or inhibited by the foreign ones.
Bicoid and nano genes gradient regulate the expression of the gap, pair-rule, and segment polarity genes.

Which class of Lever is being described if you are standing on tiptoes and if: The Fulcrum is at the metatarsal and phalanges, which is at one end of this lever on the anterior side of the body. The Load is your body weight which is in the middle of this lever. The Effort is exerted by the gastrocnemius and soleus muscles at the calcaneal (Achilles') tendon on the other side of this lever on the posterior side of the body.
Answer:
Second class lever
Explanation:
A second class lever is when the resistance ( load/weight ) is placed in between the axis ( Fulcrum which is formed by the metatarsal and Phalanges ) and the force ( Achilles tendon ) that is applied to the lever. hence the class of lever being described is a second class lever
There are three classes of lever ( 1st class, 2nd class and third class ) but The most common lever found in Humans are the 3rd class levers. but standing on tiptoes by an individual is a perfect example of a 2nd class lever found in a Human.
The Load being the body weight being and in the middle of this lever is
referred to a the second class lever.
The second class lever has the load in between the effort (force) and the
fulcrum. A common example is the wheelbarrow which has the load in the
middle.
In this scenario, the load which is the body is between the
effort(gastrocnemius and soleus muscles) and the fulcrum is the phalanges
which is a characteristic of a second class lever.
