Based on phylogenetic bracketing, knowledge that both birds and crocodiles have four-chambered hearts would lead us to conclude that ornithischian dinosaurs and saurischian dinosaurs also have four-chambered hearts.

ornithischian, a certain member of the humongous taxonomic group of herbivorous dinosaurs that includes Triceratops and all dinosaurs related to it more closely than birds. The saurischians make up one of the two primary types of dinosaurs, the other being the ornithischians. Ornithischians were so named because their hip bones were superficially similar to those of birds, with a large portion of the pubic bone pointing down and toward the tail rather than down and forward as in other reptiles. Ornithischians, despite their name, are not related to birds, which evolved from theropod saurischian dinosaurs.

Theropods and sauropodomorphs are the two major groups of saurischians. Theropods were two-legged carnivores that evolved into birds at least 144 million years ago from theropods. Like all other tetrapods, saurischian, or "lizard-hipped," dinosaurs had pelves (hips) made up of three elements: the ilium, ischium, and pubis. The saurischians are divided into two groups. Sauropoda were large herbivores that included Apatosaurus and Diplodocus.

To become a fossil, an animal must remain buried for thousands or millions of years until it (and the layer around it) turns to rock. hence option a is correct answer.

The record of life preserved in stone monuments is preserved in fossils. Nearly all living things have the ability to leave behind fossils, but typically only the tough components of plants and animals do so. Animals' muscles, skin, and soft internal organs disintegrate quickly and are rarely preserved, but their bones and shells are suitable candidates for fossilization. Soft animals like jellyfish and worms have almost no fossil records. There are several ways that fossils are created, but the majority occur when an animal or plant dies in a wet environment and is buried in mud and silt. Fast-decomposing soft tissues leave behind hard bones or shells. Sediment accumulates on top of it and forms rock over time.

Answer:

DENSITY is a physical property of matter, as each element and compound has a unique density associated with it.

Density is the number of things—which could be people, animals, plants, or objects—in a certain area.

The density of an object is the mass of the object compared to its volume. The equation for density is: Density = mass/volume or D = m/v.

A measure of the quantity of some physical property (usually mass) per unit length, area, or volume (usually volume).

Mass density is a measure of the mass.

High glycogen stores and low in mitochondria-  is true of fast glycolytic fibers.

What is glycolytic fiber?

Anaerobic glycolysis, which yields less ATP per cycle, is the main method used by glycolytic fibers to make ATP. As a result, glycolytic fibers lose energy more quickly. The structural components of slow oxidative fibers maximize their capacity to produce ATP via aerobic metabolism.

Anaerobic glycolysis is the main source of ATP for fast glycolytic fibers. They have a lot of glycogen, which allows them to produce ATP quickly. These fibers have extremely few mitochondria due to their dependency on anaerobic metabolism, which results in poor oxygen availability.

The concentration of protons (H+) increases if oligomycin, an inhibitor of ATP synthase, is added to mitochondria suspended in a buffered medium.

The Krebs cycle, oxidative phosphorylation, and glycolysis are the three primary phases of cellular respiration.

In the cytoplasm, glycolysis produces pyruvate. For every molecule of glucose produced during this process (glycolysis), two molecules of pyruvate are produced.

Additionally, during glycolysis and the Krebs cycle, Nicotinamide Adenine Diphosphate (NADH) is created in its reduced form.

The electron transport chain consumes NADH during oxidative phosphorylation. By pumping protons (H+) across from the mitochondrial matrix to the intermembrane gap, NADH is employed to establish an electrochemical gradient.

An ATP synthase uses this electrochemical proton gradient later on to create ATP. In conclusion, oligomycin DOES NOT CHANGE the concentration of pyruvate or NADH, but it DOES INCREASE the concentration of protons (H+) in the mitochondria.

The transmission of specific epigenetic markings to offspring is referred to as epigenetic inheritance.

Generally speaking, epigenetics refers to changes in a cell's gene expression profile that are not brought on by modifications to the DNA sequence. In some circumstances, the paternal contribution is the primary source of epigenetic inheritance. It is crucial to demonstrate that the inherited phenotype requires passing through the gametes when considering transgenerational epigenetic inheritance (i.e., sperm and eggs). The fact that stressed-out moms generate stressed-out offspring is an instructive illustration.

Only the fourth generation can be deemed "event-free" and unblemished since a pregnant woman's exposure to a given environmental factor may even directly damage the germ cells of the kids.

An ecosystem's overall energy content must be less than that of the lower trophic levels if there are any great white sharks present.

The fundamental framework of interaction in all biological communities, the trophic pyramid is defined by the way that food energy is transferred from one trophic level to the next throughout the food chain.

The autotrophs, which are the ecosystem's main producers, make up the base of the pyramid. Other organisms in the ecosystem are consumers called as heterotrophs, but they all rely, either directly or indirectly, on the primary producers for food and energy. Energy is lost as heat at every trophic level in all biological ecosystem as organisms need energy for metabolic tasks like keeping warm and digesting food. The amount of energy available decreases with the trophic level of the organism. For instance, the tremendous quantity of solar energy that plants and other autotrophs (primary producers) have access to is only partially converted into food energy. The biomass of the plants that herbivores and detritivores (principal consumers) eat limits how much accessible energy they can absorb. As a result, carnivores that eat herbivores, detritivores, and other carnivores, as well as those that consume other carnivores, have access to the least amount of energy.

Neuroligins induce presynaptic differentiation and neurexins induce postsynaptic differentiation. Recent protein interaction assays and cell culture studies demonstrate the selectivity of function conferred on either partner by alternative splicing. Insertion of β-neurexin into site 4 selectively promotes GABAergic synaptic function, whereas insertion of neurolysin-1 into site B selectively promotes glutamatergic synaptic function. Although early knockdown and knockout studies suggest that neurexins and neuroligins play important roles in synaptic transmission, particularly GABAergic synapses, assessing the in vivo function of these complex protein families needs further research.
