Answer:

B.

Explanation:

Glucose is an organic molecule that stores ATP or energy while Adenosine triphosphate (ATP) is an energy-carrying molecule.

ATP used as an active energy source over glucose because ATP is a shorter process and releases energy in a single reaction as glucose first converted into ATP and then used as energy in cellular respiration.

Hence, the correct option is "B".

Answer:

directional selection

Explanation:

The directional selection is a type of Darwinian selection where a particular phenotype is favored in the population, thereby modifying the allelic frequencies to increase the proportion of the favored phenotype. Biston betularia, also known as peppered moth, is a species that was influenced by directional selection in its recent past. Before the industrial revolution, the frequency of light-colored moths was predominant compared to the darker-colored phenotypes, because this color has higher adaptive fitness in a clean, no pollution environment, thereby light-colored moths were able to avoid predatory birds. However, during the industrial revolution, the frequency of dark-colored moths increased in response to pollution (i.e. darker environment), thereby conferring a higher adaptive fitness to darker phenotypes.

Answer:

The two strands of DNA are replicated in different ways

Explanation:

DNA replication is a process that occurs during the S phase of the cell cycle that consists of making two identical copies of the double-stranded DNA molecule, which subsequently are distributed in the daughter cells during cell division. During this process, DNA polymerase can add nucleotides in 5' to 3' direction, but not in 3' to 5' direction. In consequence, the DNA strand that has 3’ to 5’ directionality can be synthesized directly, while the DNA template strand that has 5’ to 3’ directionality can't be synthesized in a continuous manner and thereby it is created by adding small DNA fragments, which are known as Okazaki fragments (150-200 nucleotides in size).

Explanation:

I selected Panel 1 as the ideal incubation site for culturing microbes because the environmental conditions such as temperature, humidity and nutrients medium etc are optimum. Microbes need a specific environmental conditions for its growth and development. If the environmental conditions are not suitable so it adversely affected the growth and development of microbes.

Answer:

The correct answer is B

Explanation:

Transposons need to regulate their copy number to avoid errors with chromosomal pairing during meiosis and mitosis such as unequal crossover.

A typical example of this error is called the Alu Sequence or Elements. Alu elements contain more than one million copies found everywhere in the genome of human beings.

Many inherited human diseases such as cancer are related to Alu insertions.

Answer:

Speciation is defined as an evolutionary process in which one population evolves into a distinct species.

Speciation in reverse, or despeciation is defined as the extinction of an old species due to combining with evolved species to produce hybrid species but it conserves biological lineage.

In the given research, the term used despeciation or speciation in reverse is appropriate as hybrid species resulted from interbreeding of Galapagos two finch species conserved the biological lineage but also loss one of the species Darwin discovered.

Answer:

Speciation is the method by which unique species evolve from a common ancestor. In this case, two of these species that split from a common ancestor interbred and created a hybrid. This hybrid was apparently stronger and possibly better adapted to the environment, which led to extinction of a species formed by the initial speciation event.

No sign of testicular development in boys and breast development in girls.

Explanation:

Complications like no sign of testicular development in boys and breast development in girls occurs if an organ develop very late. There are many causes of this type of complications such as long term illness, eating improper food and disorder of sexual development. Sometime these complications  also occurs due to genetically. These complications should be treated well with medication and use of nutritious food. These medicines increases the performance of sex hormones in order to initiate puberty.

Answer:

The correct answer is - option B. They are small because they lack a nucleus.

Explanation:

Red blood cells or erythrocytes are specialized cell that produce in bone marrow and have specific role such as carrying oxygen from lungs to deliver it to the various organs and carry out carbon dioxide.

In mammals these cells lack cell organelles such as nucleus and mitochondria, a major factor that determined its smaller size. The size of RBC are move through narrow vessels throughout a organism because of its specific size and shape that provide it space for hemoglobin and allow to be flexible and bend to move through narrow vessels.

Thus, the correct answer is : option B. They are small because they lack a nucleus.

The Middle Latitudes have cyclones and anticyclones

Explanation:

The Middle Latitude is a spatial region of the earth which are found between the tropics and the polar circles.

The climate in this region of the earth is usually very windy thereby forming cyclones and in serious conditions typhoons and hurricanes. The Middle Latitude is thereby characterized by cyclones and anticyclones.

Answer:

The purine ring is built onto ribose-5-phosphate of PRPP for its de-novo nucleotide biosynthesis, while the ring structure of the pyrimidine bases are synthesized separately and then coupled to ribose-5-phosphate via the C-N glycosidic bond.

Explanation:

Purines are produced as bases attached to the ribose 5-phosphate (pentose sugar). The adenine and guanine nucleotides derive from inosine monophosphate (IMP), which is synthesized on an existing ribose-phosphate. Thus, purine bases are built on a ribose sugar that is directly attached to the pyrimidine ring. On the other hand, pyrimidines are produced from the carbamoyl phosphate precursor. In this case, the ribose-5-phosphate pentose sugar is attached after the pyrimidine ring is made.

Answer:

This question seem incomplete

Explanation:

This question seem incomplete. However, if the strand of the second fragment is what is provided above, then the answer is 51

This strand/fragment is definitely a DNA strand because of the absence of uracil (U) or because of the presence of thymine (T). The four bases in a DNA are adenine (A), Thymine (T), cytosine (C) and Guanine (G). These bases also bind to one another in the pattern described below

A ⇆ T

G ⇆ C

Hence, the adenine (A) on one strand can only bind to thymine (T) on the complementary strand (and vice versa) while the guanine (G) on one strand can only bind to cytosine (C) on the complementary strand (and vice versa).

Hence, the letters seen is the question are representations of bases in a DNA strand/fragment. The number of letters/bases here are 51

Material Safety Data Sheet (MSDS) contains information related to occupational safety and health. The MSDS provides knowledge on the safe handling of chemicals. Thus, option A is correct.

Material Safety Data Sheet (MSDS) is the data safety sheet that states the rules and details of handling and using the laboratory chemicals that are related to health. It is of great importance as it allows the learning of chemical hazards.

Before entering the lab and using the chemicals one should read the MSDS book so to get aware of the handling and precautions that have to be taken while performing any experiments. To work safely one should know its danger and should be prepared for emergencies.

Therefore, the MSDS provides knowledge on the handling of hazardous chemicals.

All of the following are examples of organic matter soil except

A. Decaying plants

B. Bacteria

C. Fungi

D. Water

The answer to this question is D. Water

Explanation:

Organic matter derives from living beings, due to this, organic matter is considered as a biological product. In this context, materials such as decaying plants are organic matter because they derive from living organisms and contain biological molecules (most contain carbon). This category does not apply to water, which is composed of hydrogen and oxygen and does not derive from living beings. Thus, the one that is not organic matter is water.

Answer:

a. Reduced siRNA-mediated mRNA degradation

Explanation:

The TRBP (transactivation response element RNA-binding protein) is an RNA-binding protein that forms the Dicer complex, which is involved in epigenetic pathways such as those mediated by the RNA interference (RNAi) mechanism. RNAi is a key process where small non-coding RNAs such as, for example, small interfering RNAs (siRNAs) and microRNAs (miRNAs) can inhibit target gene expression at posttranscriptional level by different mechanisms (including the degradation of target mRNAs). A null mutation of this cofactor will alter the Dicer complex, thereby also affecting RNAi pathways mediated by small interfering RNAs.

Answer:

The options are

A.heat exchange between two solids

B.the decomposition of a compound into its constituent elements

C.the precipitation of a solid

D.none of the above

The answer is

C.the precipitation of a solid

Dispersal of matter involves the process whereby there is more space occupied by the resulting element/compound than the initial one. For example the conversion of liquid to gas means that it has an increase in the dispersal of matter as the gas particles will contain more space when compared to a liquid.

Precipitation of a solid means conversion of a liquid to a solid. A liquid is known to contain more space which means there is a decrease in the dispersal of matter.

The process that involved the reduction in the dispersal of matter should be the precipitation of a solid

It refers to the process in which it contains the additional space that should be occupied. Like the conversion of the liquid to gas represent there should be increment in the disperson of the matter since the particles of the gas comprise more space at the time when the comparison is to be done with the liquid. Here, precipitation of the solid represent the transformation of the liquid to the solid.

Answer:

genetic variation

Explanation:

Genetic variation refers to the difference in genetic content of organisms within a population. The genetic makeup of living organisms are made up of GENES, which exists in contrasting pairs called ALLELES. Each allele is responsible for variation in traits exhibited by the organisms. Differences in the allelic content of organisms of the same species leading to the display of varying phenotypic characteristics is referred to as GENETIC VARIATION.

This is the case in the example given in which four birds in a population possess a range of wing and feather colors i.e light brown feathers with darker wings, dark feathers with lighter wings, medium brown feathers with light wings, and medium brown feathers with very dark wings, all resulting from a variation in their genetic content. Hence, this is an example of GENETIC VARIATION.

Answer:

During intense exercise:

lung capacity increases

vital capacity increases

respiratory capacity increases

functional residual capacity increases

tidal volume increases

the inspiratory and expiratory reserve volumes decrease as does the residual volume.

Explanation:

Residual volumes decrease because having better lung capacity, better development of the secondary skeletal muscles that collaborate in expiration and inspiration, these are given in a better way, and more effectively.

If these processes take place more efficiently, their potentiality increases and expiration and inspiration move a large current of air into the lungs, thus leaving less reserve airs.

Those people who have increased exhalation or inspiration reserve, have a weak activity of the musculature in the processes and function as "stagnant air" which is synonymous with a lack of physical activity or aerobic capacity.
