it is entirely normal for one testicle to be bigger than the other. Many people find that the right testicle is slightly larger and the left hangs lower. A difference in size is usually nothing to worry about, though it can occasionally indicate a problem.

This is perfectly normal and nothing to worry about. Either side may be slightly larger or hang lower. But be sure to tell a parent (who will let your doctor know) if you have any pain, swelling, or lumps in your testicles.

When a vein in a testicle becomes enlarged, it's called a varicocele. Varicoceles affect up to 15 percent of males. Like varicose veins in your legs, varicoceles may appear bulgy under the skin of your scrotum. They tend to form in the left testicle because the vein on the left side hangs lower.

The correct answer is C. That coffee quality is the best possible.

Explanation

A cooperative is a term that refers to a society made up of several individuals who group for the common benefit of its members. These associations are organized democratically and are administered according to the agreement established by their partners. For example, in this case, the coffee producers formed a cooperative to sell their products directly to consumers and eliminate intermediaries. In addition, they were accredited with a social certification by an accredited agency, which supports their products by indicating to consumers that their coffee is of the best quality. Therefore, the correct answer is C. That coffee quality is the best possible.

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.

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 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.

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.

Answer:

Nuclear fusion

Explanation:

Nuclear fusion is a process whereby the nuclei of two smaller atoms combine to form a much larger atom, accompanied with the release of energy. This is opposed to nuclear fission where a larger atom splits into simpler and smaller atoms.

According to this question, the process of releasing energy when two stoms combine to form a larger atom is called NUCLEAR FUSION. A very common example of nuclear fusion is the combination of hydrogen atoms in the sun to produce Helium atom, with the release of heat energy.

Answer: Mutation can affect an organism by resulting to a change in the number and structure of chromosomes (chromosomal mutation). A typical example of this type of mutation is Down's syndrome where the individual contains 47 instead of 46 chromosomes.

Mutation can also result to a change in the nucleotide sequence of the DNA molecule in a particular region of a chromosome(Gene mutation) an example of genetic mutation is sickle cell anemia

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.

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.

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

Energy pyramid accurately represents the amount of energy at each level of this food web Owls.

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.
