True. A transient ischemic attack (TIA) can result from embolization of atheromatous material from an internal carotid artery plaque that lodges in the brain.

An atheromatous plaque is a buildup of fat, cholesterol, and other substances on the inner walls of the arteries. When a piece of this plaque breaks off, it can travel through the bloodstream and get lodged in a smaller blood vessel in the brain, causing a TIA. A TIA is a temporary blockage of blood flow to the brain, which can cause symptoms such as weakness, numbness, or tingling on one side of the body, slurred speech, or temporary loss of vision.

It is important to seek medical attention immediately if you experience these symptoms, as a TIA can be a warning sign of an impending stroke. Treatment may include lifestyle changes, medication, or surgery to remove the plaque and prevent future TIAs or strokes.

Answer:

its called asexual reproduction

When a single-celled organism reproduces, asexual reproduction takes place.

Asexual reproduction is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes.

Asexual reproduction is a mode of reproduction in which a new offspring is produced by a single parent. The new individuals produced are genetically and physically identical to each other, i.e., they are the clones of their parents.

In asexual reproduction, one parent copies itself to form a genetically identical offspring. Sea turtles are an example of an animal that reproduces sexually, a volvox (green algae) is an example of an organism.

Sea-level rise as the last ice age drained river valleys to get rid of bays, and sediment now is transported to the coast rather than being trapped in bays.

What is sediment deposition?

Deposition is the act of depositing sediment that has been carried by wind, water, or ice. Pebbles, sand, mud, and salts dissolved in water are all examples of sediment movement. Later on, salts may be accumulated through evaporation or organic activity (such as the formation of seashells).

If the sediment is not restored, beaches will shrink because they lose it to deep sea. The heads of bays like the Chesapeake Bay, which were created when the lower portion of the Susquehanna valley was flooded by sea level rise at the end of the ice age, are today home to a lot of silt. As a result, the sediment from the Susquehanna does not reach the Atlantic beaches. As a result, the beaches get narrower as silt is lost to deep water, and during storms, waves cross the beaches to erode the land behind the beaches in order to collect sediment. Historically, there was a global sea level fall; however, this has no current impact on beaches. And if the ground were rising due to injection wells, the land would be expanding rather than contracting.

Bioaccumulation is the total accumulation of certain chemicals/contaminants in an organism, coming from diverse sources such as water, air, and diet. Therefore the case of mercury occurs when mercury is accumulated in an organism, for example, fish. The most common pathway for this to happen is through the food chain, nonetheless can occur through abiotic means, an example is in fish, where methylmercury is acquired through the gills.

When methylmercury is absorbed through the gastrointestinal tract & enters the bloodstream and goes rapidly to other parts of the body.

Mercury is a persistent substance, which can bioaccumulate, in living organisms, inflicting increasing levels of harm on higher-order species such as predatory fish and fish-eating birds and mammals through a process known as "biomagnification"

The release of processed mercury can lead to a progressive increase in the amount of atmospheric mercury, which enters the atmospheric-soil-water distribution cycles where it can remain in circulation for years. Mercury poisoning is the result of exposure to mercury or mercury compounds resulting in various toxic effects depending on its chemical form and route of exposure.

The major route of human exposure to methylmercury (MeHg) is largely through eating contaminated fish, seafood, and wildlife that have been exposed to mercury through the ingestion of contaminated lower organisms.

King mackerel, marlin, orange roughy, shark, swordfish, tilefish, ahi tuna, and all contain high levels of mercury.

Human activity is the main cause of mercury release, especially coal-fired power stations, residential coal burning for heating and cooking, industrial processes, waste incinerators, and as a result of mining for mercury, gold, and other metals.

Explanation:

Answer:

The Plasma membrane.

sorry, i know this is late.

Proteins are directed to the ER by the amino acid sequence Leu-His-Leu-Asp-Ala-Gln-Ser-Lys-Leu-Ser-Ser. This statement is true.

This signal sequence is usually located at the N-terminus of the protein and is recognized by the signal recognition particle (SRP), which binds to the sequence and targets the ribosome-nascent chain complex to the ER membrane.

Once the ribosome-nascent chain complex reaches the ER membrane, the SRP binds to its receptor on the ER membrane, and the nascent polypeptide chain is translocated across the ER membrane through a protein channel called the translocon. The signal sequence is then removed from the protein by a signal peptidase enzyme located in the ER membrane.

The presence of this signal sequence is essential for the correct localization and function of many secreted and membrane proteins, making it an important element of protein trafficking and secretion pathways in eukaryotic cells.

Oil spill has detrimental effects on the environment.

During transportation of oil, the leakage of oil that occurs in the water bodies, specifically in the oceans and seas is referred to as oil spill.

This spilled oil floats on the surface of water. This oil has effects on aquatic animals as well as the birds that hover around the water bodies. For instance, if the feathers of the seabirds get oiled, the birds can die of hypothermia. Many fishes and planktons die because of the oil spilled.

The oil droplets present on the surface are degraded by the process of photooxidation that happens due to exposure to light and oxygen. This also results in the formation of free radicals that are harmful to the water body as well as to the organisms present in water.

During exercise, there are various physiological changes that occur in the body, which can affect blood pressure. These changes include an increase in heart rate, cardiac output, and peripheral vascular resistance.

As a result, there is an increase in systolic blood pressure and mean arterial pressure (MAP). This is due to the increased demand for oxygen and nutrients by the working muscles, which requires a greater supply of blood. Additionally, the release of adrenaline during exercise also contributes to the increase in blood pressure.

However, with regular exercise, the body becomes more efficient at delivering oxygen and nutrients to the muscles, resulting in a reduction in peripheral vascular resistance and a decrease in blood pressure. Therefore, regular exercise can help to lower blood pressure and improve cardiovascular health.

Answer:micro organism.

Explanation:

Energy transfer among antenna pigment molecules occurs through a process called resonance energy transfer or Förster resonance energy transfer (FRET).

In light-harvesting systems, such as photosynthetic organisms, antenna pigment molecules, like chlorophyll or other light-absorbing pigments, capture photons of light. These pigments are organized in protein complexes called antenna complexes. When a pigment molecule absorbs a photon, it gets excited to a higher energy state.

Within the antenna complex, energy transfer occurs through FRET. The excited pigment molecule (donor) transfers its energy to a neighboring pigment molecule (acceptor) without direct contact. This transfer happens due to the overlap between the emission spectrum of the donor and the absorption spectrum of the acceptor. The excited donor molecule transfers its energy to the acceptor by a non-radiative dipole-dipole interaction.

The energy transfer process continues from one pigment molecule to another until it reaches a specialized reaction center, where the captured energy can be utilized for photosynthesis. This efficient energy transfer mechanism ensures that energy absorbed by the antenna complex is effectively channeled to the reaction center, enhancing the overall efficiency of light harvesting in photosynthetic organisms.

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.
