Hydras and jellyfish both live in a freshwater lake that is slowly being acidified by the runoff from a chemical plant built upstream. Which population is predicted to be better able to cope with the changing environment

Answers

Answer 1

Answer:

Hydras

Explanation:

Algae support hydras because they provide hydras oxygen. Hydras have regenerative ability; they do not appear to die of old age, or to age at all. But sometimes, disease, predators and water contamination kill off hydras before they can achieve "immortality".

Jellyfish need to stay in the water to survive. They get their oxygen from their really thin skin. In some cases, it has been found that jellyfish have an immune system that presents bacterial-specific responses.

In the absence of an adaptive immune system, Hydra polyps employ an elaborate innate immune system to detect and interact with microbes using their two cell layers as efficient defense barriers, making them survive longer or have better defense against the chemicals.

Also take into consideration, what chemicals/acids are being put into the lake and the "age" of the hydra/jellyfish.

Answers

The vesicle that originates from the Golgi apparatus and contains a variety of digestive enzymes is the lysosome.

What is the function of the lysosome?

The lysosome is a spherical structure rich in enzymes. Lysosome is a cellular organelle found only in eukaryotic cells that acts in intracellular digestion, ensuring the degradation of materials captured by the cell, as well as the recycling of some cellular components (autophagy).

With this information, we can conclude that Lysosomes are cellular organelles, formed in the Golgi complex and full of digestive enzymes such as proteases, lipases and nucleases.

Which type of training would most likely lead to increased levels of testosterone, insulin-like growth factors, and growth hormone

Answers

Overload training that is of a high intensity with limited rest periods would most likely lead to increased levels of testosterone, insulin-like growth factors, and growth hormone.

Roles and Integration for Cellular Development and Growth With Exercise:

The integrated communication of numerous physiological systems that control cellular growth and development is substantially facilitated by hormones. Three important hormones—testosterone, the growth hormone superfamily, and the insulin-like growth factor (IGF) superfamily—are regarded as the "anabolic giants" in cellular growth and repair, though the precise hormonal influence must be taken into account in the context of the entire endocrine system and its relationship with other physiological systems. Glucocorticoids, particularly cortisol, must also be taken into account in addition to these anabolic hormones because they frequently have a profoundly opposing effect on human skeletal muscle anabolism.

three events on the earth where solar energy is used for natural phenomena​

Answers

Answer:

Solar phenomena are the natural phenomena occurring within the outer atmosphere of the Sun. These phenomena take many forms, including solar wind, radio wave flux, solar flares, coronal mass ejections, coronal heating and sunspots.

Answer:

Sunspots, Solar flares, and Coronal mass ejections (CMEs).

Explanation:

Sunspots:

Sunspot pair surface phenomena occur when a magnetic flux tube breaks the star's surface, loops about, and then re-enters the star. These tubes have broken the surface after rising buoyantly from the internal depths. The lengthy response is substantially more difficult because the entire procedure is so challenging! Let's start with the most basic question: Why do magnetic flux tubes rise to the surface buoyantly at all? If you visualize a star in thermal equilibrium with a single, isolated horizontal (i.e., perpendicular to the direction of gravity) magnetic field tube. With the subscripts I for within the tube and e for outside the tube, the fluid's attributes are pressure, density, and temperature. Since stars are essentially in a state of hydrostatic equilibrium, the pressure inside and outside of the tube must be identical. However, because of the magnetic field, there is also magnetic pressure inside the tube. Thus, p e = p e + p m, where p m is the magnetic pressure, is what we have. Now that we are in thermal equilibrium, we can assume that T i = T e = T, the temperature inside and outside, is the same since thermal diffusion moves far more quickly than ohmic (magnetic) or viscous molecules. Since rho e > rho i must be true for these two sides to be in balance, the region with the magnetic field will rise since it is less dense and buoyant than the other side. In two truly outstanding publications published in 1955, Eugine Parker originally defined this process. He basically came up with a lot of theories about how the Sun's various aspects would develop, and after decades of testing, nearly all of these theories have proven to be accurate. He inspired the Parker Solar Probe, which I think is the first and only mission NASA has launched into orbit with his name attached. The reason why a tube of magnetic flux might ever form at the surface is solely explained by this one step (the answer being that it rises there from the deep interior due to a mechanism known as magnetic buoyancy). There is much more to this, including why the Sun even has a magnetic field, how it maintains the field, why sunspots are dark, why they behave in such a predictable way (see the butterfly diagram, which depicts the 11 or 22-year solar cycle by which sunspot pairs reverse polarity, migrate, and cycle in occurrence rate) and much more!

Solar flares:

An enormous, unexpected burst of energy from the Sun is known as a solar flare. They don't pose a serious threat to humanity since the Earth's atmosphere effectively shields us from them. However, they could be harmful to people and spacecraft beyond the Earth's atmosphere. A far greater event known as a Coronal Mass Ejection (CME), which involves the emission of a tremendous amount of energy as well as matter, can occasionally occur alongside solar flares. Again, the atmosphere and magnetosphere of the Earth provide protection for us people on the ground. Theoretically, if a CME orders of magnitude larger than anything we've ever seen were to be directed at Earth for some reason, it could overwhelm the magnetosphere and atmosphere and have a significant negative impact on biological life. However, at that point, you're not talking about a solar flare or a CME; rather, you're talking about some other mechanism that is disrupting the Sun.

Coronal mass ejections:

Strong, protracted solar flares and filament eruptions can cause large clouds of solar plasma, known as coronal mass ejections (or CMEs), to be flung away from the Sun. The OSO 7 spacecraft's coronagraph observations between 1971 and 1973 provided the first evidence of these dynamic occurrences. A tiny disk placed over the Sun by a coronagraph causes a solar eclipse. Because they are so weak, coronal mass ejections cannot be seen in any other way. White-light coronagraphs are equipped with the SOHO and STEREO spacecraft to find coronal mass ejections. Strong geomagnetic storms are mostly caused by coronal mass ejections, making them crucial to monitor. A coronal mass ejection is seen in the animation below as viewed by LASCO on board the SOHO satellite.

Answers

The answers is All of the choices

The source by which carbon atoms may return to the atmosphere or water is respiration, combustion, as well as erosion. The correct option is B.

What is carbon cycle?

The carbon cycle describes the continuous movement of carbon atoms from the atmosphere to the Earth and then back into the atmosphere.

Because our planet and its atmosphere form a closed system, the amount of carbon in this system remains constant.

It is critical for our planet's climate and carbon balance to remain stable. Carbon is the lifeblood of the Earth, and the carbon cycle regulates it naturally. The Earth would be frozen if it didn't have it.

The maximum amount of carbon is usually stored in rocks and sediments, with the remainder in the ocean, atmosphere, and living organisms.

Carbon atoms can return to the atmosphere or water through respiration, combustion, or erosion.

Thus, the correct option is B.

A beta barrel is a beta sheet made of tandem repetitions that twists and coils to form a closed toroidal structure in protein structures. The first strand of the beta barrel is connected to the last strand (hydrogen bond). Many beta-barrels have an antiparallel arrangement of the beta-strands. The majority of them are proteins that are soluble in water and typically bind hydrophobic ligands in the middle of the barrel, like lipocalins. More than 600 proteins with a variety of functions have been shown to include the beta barrel shape.

In many cases, the strands contain alternating polar and non-polar (hydrophilic and hydrophobic) amino acids. As a result, the polar residues are oriented toward the solvent-exposed surface of the barrel and the hydrophobic residues are oriented into the interior of the barrel to form a hydrophobic core.

IgG antibodies are monomers and do not agglutinate immediately (termed non-agglutinating antibodies).IgG antibodies are powerful molecules that have the special capacity to connect foreign particles to innate immune cells. IgG antibodies attach to cellular Fc receptors with a low affinity while recognizing antigens with a high affinity. Immune complexes are formed during these encounters, producing high-avidity interactions.

Answer:

Glycolysis is the metabolic pathway (process) that converts one molecule of glucose into two molecules of pyruvate. In the process the pathway forms two molecules of ATP and one molecule of NADH from two molecules of ADP and phosphate and one molecule of NADH.

The importance of glycolysis is that it provides the cell with a small amount of readily accessible energy in the form of ATP and it provides the mitochondria with a source of pyruvate. There, the pyruvate can be completely oxidized to CO2 and H2O and form a large amount (~28 molecules) of ATP from ADP and phosphate. More importantly, it provides red blood cells with there only source of ATP (since they have no mitochondria).

Germinal cells can most likely divide indefinitely due to the activity of an enzyme called ________.

Answers

Germinal cells can most likely divide indefinitely due to the activity of an enzyme called Telomerase.

The telomeric sequences are extra sequences which are reduced during several rounds of replication. However, these are restored by the enzyme telomerase which keeps the length of the telomere sequence enough to undergo several rounds of replication. Generation after generation, germ cells must precisely transmit genetic information. They have a lot of telomerase activity to stop the genetic material from being lost during meiosis. The parents' genetic material is kept intact thanks to the high level of telomerase.The primary region of the chromosome, which contains the genes necessary for life, would become shorter without telomeres with each cell division. Telomeres thereby permit cell division without gene loss.

Crabs are omnivores. The smaller crabs can eat seaweed, worms, shrimp, algae, etc while the larger ones can eat mussels, snails, and squid. Crabs can change their feeding grounds because of environmental changes. Mussels being the prey of crabs were forced the development of new traits to ensure their survival. They started to produce thicker shells. This allowed the mussels with thicker shells to survive as they would not get eaten by the crabs, thus undergoing natural selection. The development of said trait improved the survival rate of mussels and prevented them from going extinct due to predation.

What type of amino acids would you expect to find at the core of a water-soluble globular (solid-spherical) protein

Answers

Hydrophobic amino acids are buried at the core of a water-soluble globular protein.

What makes globular proteins water soluble?

Numerous hundreds to thousands of amino acids are used to make proteins. The arrangement of amino acids within a protein molecule determines its ultimate form. A protein molecule is classified into two classes—fibrous proteins and globular proteins—based on its final shape.

The structure of globular proteins resembles a ball or a globe. A globular structure is created by the folding of different amino acid chains. The two most significant globular proteins present in the human body are hemoglobin and myoglobin. The hydrophobic side chains of the amino acids are hidden inside the cores of the domains whereas the hydrophilic side chains are located on the surface of the molecule thanks to the arrangement of the amino acids.

The hydrophobic amino acids can be buried in the center of globular proteins due to interactions between the hydrophobic groups in their side chains. This is the fundamental property of globular proteins that makes them water soluble.

Examples of hydrophobic amino acids are phenylalanine,  alanine, valine, etc.
