THE NIGHTMARE

I woke up with a start, sweating profusely, my heart pounding erratically against my chest. My hands were shaking uncontrollably and I held my pillow close to my chest to clam my nerves. I had heard it. There was no doubt in it. A loud, high-pitched shriek, which sounded nothing like a human cry. It was surreal, making a shiver to creep up my spine. I twisted my hands together in nervousness, and murmured a prayer to god. The ghostly sound had resonated from beneath my bed. I had read way too many horror stories to not be scared by now. My throat felt dry and parched and I longed for a sip of water. But I had to go downstairs to fetch the jug. That meant I had to get down from my bed. And there was no way I would do that. Not now, when I was literally scared to death. I swallowed hard. My breathing had slowed down a bit but my heartbeat was still erratic. I perked up my ears and waited to see if the shrieks continued. I badly wanted to cover myself with my blanket but I was too scared to move an inch. I waited for about a minute and could hear no sound. This eased me a bit. Just when I mustered the courage to lie back down and go back to sleep, I felt a shadow whisk past me, sending the curtains flying. I brought my hands to my mouth to stop myself from crying out in terror. It was the silhouette of a girl, a tall, slender figure that I was sure by now was somewhere around me. I felt my eyes brimming with tears but I held my cries back. It was when the shadow reappeared, this time closer to me, near my nightstand. And before I could register what was happening or cry out loud for help, the figure advanced towards me, and all of a sudden, held me in a death grip. I felt myself being choked so tightly that no sound was escaping my mouth, black dots swimming in my vision. Soon enough, I plunged into darkness. After what felt like hours, I opened my eyes to be greeted with the golden rays of the sun streaming in through the window near my bed. I had a slightly blurry memory of yesterday night. I felt around my surroundings, and was met by relief when I could feel the blankets and my pillow beside me. Overjoyed by the fact that I was safe, and that it all had been just a silly nightmare, I thanked God and got out of bed to start my day.

The somatic and autonomic nervous systems differ in all of the following except D) all of the neurotransmitters

The peripheral nervous system is the nervous system consisting of pairs of cranial nerves and spinal nerves that leave the brain and spinal cord. The nervous system is divided into two, namely the somatic and autonomic nervous systems which have different functions.

The somatic nervous system works by controlling everything that is conscious and the autonomic nervous system controls activities that are carried out unconsciously. Therefore effector, efferent pathways, and their target responses differ except for neurotransmitters which carry and transmit messages between neurons. Neurotransmitters are chemical compounds in the body that carry messages across the synaptic gap from one neuron to another in the central nervous system.

The shape and size of the maxillary angle and palate can be related to the size of the mouth of a species. The maxillary angle, which is the angle on the side of the upper jaw between the midline and the cheekbone, can be used to predict the size of the muzzle of a species.

If the angle is larger, the proportionally larger mouth means the jaw can open and close more heavily, allowing for wider intake of food and larger incisors to cut larger pieces of food. Additionally, the shape of the palate affects the size of the mouth. Animal species with a longer and more narrow palate tend to have smaller mouths, while those with shorter and wider palates have larger mouths.

The shape of a palate also dictates how much space a species has for its teeth, thus affecting the size of its mouth. Overall, these two factors play major roles in determining how large the mouth of a species will be, as well as how much space it will have to fit in its teeth.

The spreading out of molecules in the air from a center of concentration is caused by diffusion. Diffusion is the movement of molecules from a region of high concentration to a region of low concentration.

This process occurs due to the random motion of particles, and it is driven by the natural tendency of particles to move from an area of high concentration to an area of low concentration.

Diffusion plays a vital role in many natural processes, including gas exchange in the lungs, transport of nutrients and waste products across cell membranes, and the release of odor molecules into the air.

In each of these processes, the molecules move from a region of high concentration to a region of low concentration due to the natural tendency of particles to spread out and become evenly distributed over time.

The rate of diffusion is influenced by several factors, including the concentration gradient, the temperature of the environment, and the size and shape of the molecules involved.

Diffusion can be a slow process, particularly over long distances or in areas where the concentration gradient is small, but it is a fundamental mechanism that underlies many of the processes that allow living organisms to function and survive.

Overall, the spreading out of molecules in the air from a center of concentration is an essential process that is driven by the natural tendency of particles to diffuse and become evenly distributed over time.

Genes linked on the same chromosome tend to be inherited together, violating the principle of independent assortment.

The relative position of genes is determined by calculating the frequency of crossing-overs between genes located on the same chromosome. The closer two genes are located to each other on a chromosome, the lower is the probability that the independent distribution in the next generation violates the principle of the opposite chromosomes.

Crossing-over between them is highly likely, resulting in the formation of recombinant chromosomes. The phenotype resulting from a genotype is determined by the same distribution.

The correct answer is d. maturity. In the product life cycle, a product goes through different stages, starting with the introduction or conception stage, followed by the growth stage, maturity stage, and finally, the decline stage.

The maturity stage is the stage when a product has reached its peak in terms of sales and market share, and profits level off or decline. This is because of increased marketing outlays to defend the product against competition.

During the maturity stage, competition is high, and companies need to invest in marketing and advertising to maintain their market share. This results in increased marketing costs and lower profit margins. Companies may also need to invest in product innovation or product differentiation to stay ahead of the competition.

In summary, the maturity stage of the product life cycle is characterized by increased marketing outlays to defend the product against competition, resulting in leveling off or declining profits.

A sequence of nucleotides in the eukaryotic gene that is transcribed but removed before translation is an: intron.

Eukaryotic genes contain both coding regions (exons) and non-coding regions (introns). During transcription, both exons and introns are transcribed into pre-mRNA. However, before translation, the introns are removed and the exons are spliced together to form a mature mRNA molecule that can be translated into a protein.

An intron is a non-coding sequence of nucleotides within a gene, and it is spliced out during RNA processing, leaving only the exons to be translated into a protein.

The removal of introns and splicing of exons is carried out by a complex molecular machinery called the spliceosome. The spliceosome recognizes specific sequences at the boundaries between introns and exons and cuts the pre-mRNA at the appropriate locations to remove the introns and join the exons.

This process of removing introns and splicing exons together is essential for the production of functional proteins from the eukaryotic gene. It allows for alternative splicing, which is the production of different mRNA molecules and proteins from a single gene by splicing its exons in different ways.

A and D are correct. Chromosomes are found in the nucleus of cells and contain pieces of DNA, known as genes.

Chromosomes are thread-like structures that are found within the nucleus of most cells and contain the genetic material of an organism. The word chromosome is derived from the Greek words chroma, meaning “color,” and soma, meaning “body.” Chromosomes are composed of DNA, a molecule that stores genetic information, and proteins that help to package the DNA and control its function. Humans have 23 pairs of chromosomes, for a total of 46 chromosomes, while other living organisms may have more or less. Chromosomes are important because they contain the genetic information that is passed from parent to offspring and enables them to develop.

DNA is made up of complementary base pairs, which are used to create chromosomes. Chromosomes are not made of DNA, but instead are made of RNA, which is a copy of the DNA.

The pollen and ovules of the pea plant flower are haploid cells.

Pollen and ovules are both forms of gametophytes found in the pea plant flower. Pollen grains are haploid cells that are formed by male reproductive organs containing sperm cells. They are discharged into the air and then travel to the reproductive organs of the female. Ovules are haploid cells generated by the female reproductive organ and containing egg cells. When pollen grains come into contact with ovules, they can combine to produce a diploid cell that will eventually develop into a seed. Pollen and ovules carry distinct genetic material that is used to make the seed. This genetic material is a blend of both the male and female parent's genetic material, allowing for genetic variety.
