The image shows an energy pyramid. Vulture Coyote Prairie dog Grass Which statement about how energy flows through this ecosystem is supported by this ecological pyramid? OA. The highest trophic level has the most available energy because vultures are a tertiary consumer. B. The organisms of the second trophic level obtain their energy from the coyotes located in the third trophic level. C. The grasses' trophic level has the most energy, but only some of that energy moves to the second trophic level. D. The third trophic level is made up of prairie dogs that get their matter and energy from the grasses.
Answers
The third trophic level is made up of prairie dogs that get their matter and energy from the grasses (option d).
The energy pyramid depicted in the image illustrates the flow of energy through an ecosystem. In an energy pyramid, each level represents a trophic level, indicating the position of organisms in a food chain. The pyramid narrows as it ascends, indicating the decrease in available energy at higher trophic levels.
In this specific pyramid, the lowest trophic level is occupied by the grass. This makes sense because grass is a producer that captures energy from the sun through photosynthesis. As a result, it possesses the most energy within the ecosystem.
Moving up the pyramid, the second trophic level is occupied by the prairie dogs. They are herbivores that primarily consume grass for their energy needs. This demonstrates that the prairie dogs acquire their matter and energy from the grasses, supporting option D.
The third trophic level contains the coyotes, which are tertiary consumers. Tertiary consumers feed on other consumers, not producers. Therefore, option A is incorrect since vultures, not coyotes, are tertiary consumers in this ecosystem.
Option B is also incorrect because the coyotes do not obtain their energy from other coyotes located in the third trophic level. They acquire their energy indirectly from the grasses through the prairie dogs.
Finally, option C is incorrect as it states that the grasses' trophic level has the most energy. While the grasses are indeed the primary producers and possess the most energy, not all of that energy moves to the second trophic level.
Thus, the correct statement supported by the ecological pyramid is option D: The third trophic level is made up of prairie dogs that get their matter and energy from the grasses.

The placenta is formed by the end of the first trimester
The heart beats and organs are formed during the first trimester.
Teeth and fur develop during the second trimester.
Three-quarters of all growth occurs during the third trimester.
Answers
Answer:
Three-Quarters of all growth occurs during the third trimester.
Explanation:
D is the only option that has anything to do with the last trimester which is what the question was asking about. Furthermore, because so much growth is occurring during this time the cow will need more food to support this growth. So, D is the best option.

The interior of the phospholipid bilayer is _______ meaning it repels polar molecules, such as water
Answers
The cell membrane's inside is hydrophobic, meaning that water won't cling to it. In order to effectively separate fluid inside the cell from fluid outside the cell, phospholipids form a two-layer cell membrane.
Why do polar molecules repelled by the phospholipid bilayer?Large hydrophilic polar or ionic molecules find it difficult to pass through the phospholipid bilayer. The cell membrane prevents the passage of any size charged atoms or molecules.
What component of the phospholipid bilayer is water-repellent?While the tails (the lipid component) are non-polar, the heads (the phospho part) are polar. The tails, which face the inside of the cell membrane, are "hydrophobic" (fearful of water), whereas the heads, which make up the exterior and inner linings, are "hydrophilic" (lovers of water).

the membrane depolarizes.
Answers
When X fires 10 times and Y fires 10 times, the result will be a subthreshold summation.
Subthreshold summation happens when two or more presynaptic inputs that are sub-threshold (i.e., they cannot create an action potential) combine their effects on the postsynaptic neuron.
Here, the postsynaptic neuron has an RMP of -70mV and a typical threshold of -55mV. When neuron X is stimulated, it depolarizes by 0.5 mV.
When X and Y are stimulated simultaneously, the postsynaptic neuron depolarizes by 1 mV, which is sub-threshold (below -55mV).
Therefore, when X fires 10 times and Y fires 10 times, the postsynaptic neuron will experience subthreshold summation and no action potential will be fired.

In 1882, Theodor W. Engelmann carried out an experiment using filamentous green algae, oxygen-requiring bacteria, a light source, and a prism. He placed the algae and bacteria together in liquid medium in a glass tank. Then he placed the prism next to the tank and the light source a bit farther away. When he directed the light onto the prism, it dispersed into its component wavelengths as shown in the diagram. He found that if one filamentous alga lined up along the distribution of wavelengths of light coming into the tank, the bacteria tended to congregate in specific areas around the algal cell. These areas correlated to the wavelengths of light striking the algal cell. Pose a scientific question that Engelmann might have asked about an algal cell after making his observations from this experiment.

Explain how membrane receptors transmit messages across the cell membrane.
Answers
The activated receptor can trigger the opening of ion channels, allowing charged particles to flow into or out of the cell, which can change the electrical properties of the cell. Alternatively, the activated receptor can activate intracellular signaling pathways by binding to and activating intracellular proteins, such as enzymes or transcription factors. These intracellular signaling pathways can lead to changes in gene expression, protein synthesis, or the activity of other intracellular proteins, resulting in a cellular response to the original signaling molecule.
Overall, membrane receptors play a critical role in transmitting messages across the cell membrane by converting extracellular signals into intracellular signaling events that ultimately result in a cellular response.

Two organisms with striped fur mate and produce offspring. Three of the offspring have striped fur but one has no stripes. The non-striped coat is probably what type of trait?
Answers
The non-striped coat is likely a recessive trait. If both parents have striped fur, it is likely that they are both heterozygous for the striped trait.
That means they each carry one dominant and one recessive allele for this trait. When they mate, there is a 25% chance that their offspring will inherit two copies of the recessive allele, resulting in a non-striped coat. This pattern of inheritance is consistent with a recessive trait.
Dominant traits can express themselves. While recessive traits cannot express themselves in the presence of dominant traits.

Answers
Water soluble hormones, such as glycoproteins or peptide hormones, cannot cross the lipidic membrane. The cell receptors for this hormones are located on the surface of the cell membrane. So, this hormones have their main activity on the cell surface.
Fat soluble hormones, for example steroids (cortisol, testosterone, estrogen), can easilly pass through the cell membrane, the receptors for these hormones are found within the cell, in the cytoplasm and the nucleus. These hormones act directly by estimulating the transcription of DNA to produce determined proteins.

What is the cell process of mitosis?The cell process of mitosis is a cell division phenomenon that generates two genetically identical daughter cells as the parental cell, while meiosis generates four daughter cells that have half genetic material when compared to the parental cell which are called gametes or germinal meiotic cells that fuse during the process of fecundation in order to develop a diploid cell and thus restore the normal number of chromosomes in somatic cells.
Therefore, with this data, we can see that the cell process of mitosis and meiosis are different in the sense mitosis involve one division cycle while meiosis involves two division cycles and it generates 4 daughter cells.

What is ridge push?
Answers
Answer:
Ridge push (also known as gravitational sliding) or sliding plate force is a proposed driving force for plate motion in plate tectonics that occurs at mid-ocean ridges as the result of the rigid lithosphere sliding down the hot, raised asthenosphere below mid-ocean ridges. Although it is called ridge push, the term is somewhat misleading; it is actually a body force that acts throughout an ocean plate, not just at the ridge, as a result of gravitational pull. The name comes from earlier models of plate tectonics in which ridge push was primarily ascribed to upwelling magma at mid-ocean ridges pushing or wedging the plates apart. Brainliest?
