The Clean Water Act regulates pollutants in U.S. waters and establishes quality standards for ______.

Answer:

True

Explanation:

During prophase, the nuclear membrane is broken down and spindle fibers are formed while the chromosome condenses.

During anaphase, the chromosome pulls apart to the opposite side of the cell, and during telophase, the two newly formed nuclear membranes are reconstituted.

Nucleolus and nuclear membrane re-emerge and the nucleus returns to an interphasic state with chromatin as fine threads. The nuclear membrane re-emerges from fragments of the parent cell nuclear envelope and other parts of the intracellular membrane. This occurs during the telophase.

Answer:

B. Spring

Explanation:

When ground water, like the aquifer, rises to surface level it creates a spring.

An unconfined aquifer is found near the ground surface and is under the atmospheric pressure at the water table. It intersects with the earth's surface to create spring. Thus, option B is correct.

Spring is a natural water discharge from the earth's surface into the ground or another water body. They are formed when an unconfined aquifer intersects with the surface.

The unconfined aquifer is formed below the rivers and rises to the upper surface due to atmospheric pressure. It results in the formation of the spring from between the rock surfaces.

Therefore, an unconfined aquifer creates spring.

The cranial nerve that is purely sensory is the olfactory nerve. The olfactory nerve is the first cranial nerve. It is responsible for the sense of smell. It consists of sensory neurons that transmit the sensation of odor from the nose to the brain. The correct answer is option(c).

The olfactory nerve is purely sensory, while the rest of the cranial nerves have both sensory and motor functions. Compared to a coma, a patient in a permanent vegetative state lacks both awareness and wakefulness. A person in a permanent vegetative state has no awareness of self or their surroundings. They are also unaware of any pain or discomfort that they may be experiencing.

The brain stem continues to function in a person in a permanent vegetative state. However, the higher cortical functions of the brain, including awareness, are lost. The cerebral cortex is the outermost surface of white matter covering the cerebrum. It is composed of a thin layer of gray matter that contains neurons, dendrites, and axons. The cerebral cortex is responsible for the perception of sensory information, voluntary movement, and the integration of information from various brain regions.

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.

During dehydration, the plasma volume decreases.

Dehydration refers to a state of insufficient fluid intake or excessive fluid loss from the body, leading to a decrease in total body water content. One consequence of dehydration is a reduction in plasma volume, which refers to the liquid component of blood.

When the body becomes dehydrated, there is an imbalance between water intake and water loss, resulting in a decreased volume of fluid circulating in the bloodstream. This reduction in plasma volume can have several physiological effects. It leads to an increase in blood osmolality, which triggers mechanisms to conserve water and maintain fluid balance.

The body may respond by constricting blood vessels, redistributing blood flow to vital organs, and increasing the release of antidiuretic hormone (ADH) to reduce water loss through urine.

The theory that sees aging as a process whereby cells are assumed to have a limitation on the number of times they can reproduce to repair damage is called the "telomere theory of aging." This theory proposes that aging is caused by the shortening of telomeres, which are the protective caps at the ends of chromosomes.

Each time a cell divides, the telomeres become slightly shorter, eventually reaching a critical length at which the cell can no longer divide and becomes senescent or dies. This process is thought to contribute to the progressive decline in tissue function that is characteristic of aging.

The wear-and-tear theory of aging, on the other hand, proposes that aging is caused by the accumulation of damage and the failure of repair mechanisms over time, leading to the breakdown of tissues and organs. This theory suggests that aging is a result of the body's inability to keep up with the constant wear and tear of everyday life.

While both theories have some evidence to support them, the telomere theory is more specifically related to the limitations of cell reproduction, while the wear-and-tear theory is more broadly related to the accumulation of damage and failure of repair mechanisms.

Answer:

The cell membrane is selectively permeable, which controls the movement of materials in and out of the cell by passive and active transport.

Explanation:

According to this question, animal cells are made up of the following contents: 90% water and 10% protein, carbohydrates, nucleic acid, lipids and other molecules. The cell regulates this internal composition in a stable way via a process called HOMEOSTASIS.

The animal cell is able to regulate or maintain a stable internal composition by the possession of a selective permeable membrane called CELL MEMBRANE. The cell membrane is semi-permeable in the sense that it allows the entry of some molecules into and out of the cell and blocks others.

Some molecules are allowed by the cell membrane without the need for energy input in a transport called PASSIVE TRANSPORT while some requires energy input in a transport called ACTIVE TRANSPORT.

The correct answer is iterative evolution. A crocodile-like morphology evolved independently in a group of Triassic reptiles called phytosaurs, and later, after phytosaurs were extinct, in true crocodiles. This is an example of iterative evolution.

Iterative evolution is the development of similar structures or forms independently over time in separate lineages. This is frequently seen in unrelated lineages of organisms that evolve similar features through convergent evolution. The crocodile-like morphology that evolved independently in Triassic reptiles called phytosaurs and later in true crocodiles is an example of iterative evolution as they evolved independently in separate lineages. The ability of the phytosaurs to thrive in an aquatic environment likely contributed to the development of this morphology, which later allowed true crocodiles to similarly thrive.

The macromolecule that can accomplish the widest range of biological functions are Proteins. So, option B is correct.

Large biomolecules and macromolecules known as proteins are made up of one or more extended chains of amino acid residues. Among the many tasks that proteins carry out in living things include catalysing metabolic processes, replicating DNA, reacting to stimuli, giving cells and organisms structure, and moving molecules from one place to another. The primary way that proteins differ from one another is in the order of their amino acids, which is determined by the nucleotide sequence of their genes and typically causes a protein to fold into a certain 3D structure that controls its activity.

A polypeptide is an ordered sequence of amino acid residues. At least one lengthy polypeptide is present in every protein. Less than 20–30 residue polypeptides are frequently referred to as peptides and are rarely thought of as proteins.

The following steps occur during biosynthesis of a + strand rna virus.  The third step is Synthesis of viral proteins.

Viruses are tiny, nonliving particles that are unable to replicate on their own. Instead, they exploit a host cell's internal machinery to itself to proliferate and create new viruses.

A + strand RNA virus first goes through attachment and adheres to the host cell's surface before it can infect the cell. Second, it passes through penetration and uncoating, allowing its contents to enter the cytoplasm of the host cell. Third, host machinery translates the viral + sense RNA to create viral proteins. A RNA-dependent RNA polymerase is one of these proteins; it creates a complementary - strand of viral RNA before producing further + strand RNA viral genomes.

There, it discharges its sperm into the embry

Explanation:

The pollen tube enters into the ovule, through the micropyle. Inside the embryo sac, the tip of the pollen tube ruptures and the 2 male gametes are set free near the egg apparatus.
