Explanation:

because thats the mane function off muscle tissues and they dont really do any other things

The function of muscle cells is to contract to cause movement in the body. So the correct option is C.

Muscle tissue is composed of muscle cells. These cells have the unique ability to ability to contract and relax which results in movement of the parts of our body.

The muscle is compact with muscle cells. It is well supplied with blood vessels. These are long and slender and thus they are sometimes also referred to as muscle fibres.

These cells are arranged usually in the form of bundles or layers. They are surrounded by connective tissue. There are two contractile proteins present in the muscle tissue called Actin and myosin.

They are categorized as skeletal muscle tissue, smooth muscle tissue, and cardiac muscle tissue.

Therefore the correct option is C.

Explanation:

two ATP molecules are required to start the process. initially when glucose is phosphorylated it requires energy which is provided by the hydrolysis of ATP so 2 molecules are used up.

Glycolysis does not yield four molecules of ATP because two ATP molecules are required to start the process. Hence option C is correct.

ATP stands for adenosine triphosphate. It is defined as an organic substance that fuels a variety of functions in living cells, including chemical synthesis, condensate dissolution, nerve impulse transmission, and muscular contraction. When the cell needs energy, ATP can be taken out and used to fuel processes or stored for use in later ones.

Glycolysis is defined as the pyruvic or lactic acid is produced as a result of the enzymatic breakdown of a carbohydrate using phosphate derivatives, and energy is stored in ATP's high-energy phosphate bonds. A linear metabolic process called glycolysis uses enzymes to catalyze reactions that break down glucose into two molecules of pyruvate or lactate depending on whether oxygen is present.

Thus, Glycolysis does not yield four molecules of ATP because two ATP molecules are required to start the process. Hence option C is correct.

Deglutition (swallowing) is coordinated by the swallowing center in the medulla oblongata of the brainstem.

The medulla oblongata is a vital part of the brainstem responsible for controlling many essential functions, including respiration, heart rate, and swallowing. Within the medulla oblongata, the swallowing center consists of a group of neurons that orchestrate the complex sequence of muscle movements involved in swallowing.

When food or liquid is ingested, sensory receptors in the oral cavity and pharynx send signals to the swallowing center, triggering the coordinated series of events that allow for safe and efficient swallowing. The swallowing center coordinates the contraction and relaxation of muscles involved in the movement of the tongue, soft palate, pharynx, and esophagus to propel the bolus of food or liquid from the mouth to the stomach.

No energy input is necessary to transport big proteins through the nuclear pore complex as opposed to nucleotides. Option B is Correct.

When a cell increases the amount of secreted proteins it produces, the size of the Golgi apparatus shrinks. Native folding of mitochondrial proteins should occur twice: once in the cytoplasm and again inside the organelle. Independent of the TOM complex, -barrel proteins, which are prevalent in the mitochondrial outer membrane, are imported from the cytoplasm.

These studies established the secretory pathway—rough ER, Golgi, secretory vesicles, and cell surface—as the route taken by proteins that are secreted. A protein travels via the endoplasmic reticulum, the golgi complex, and finally secretory vesicles before leaving the cell. Endoplasmic reticulum, Golgi complex, and secretory vesicle are the proper order. Option B is Correct.

a ciliate. Ciliates are a type of single-celled organism belonging to the Ciliophora.

They are characterized by the presence of numerous hair-like structures called cilia, which are used for locomotion and feeding. Cilia are short, hair-like projections that cover the entire outer surface of the cell membrane.

These cilia beat in a coordinated fashion, creating a wave-like motion that allows the ciliate to move through the water.

Ciliates exhibit a wide range of shapes and sizes, but they are typically oval or elongated in form.

They have a well-defined nucleus and often possess other specialized structures such as contractile vacuoles for osmoregulation and oral grooves for feeding.

Ciliates are also known for their ability to undergo complex cell division processes, including conjugation, which involves the exchange of genetic material between two individuals.

Observing a single-celled organism with moving cilia under the microscope is a common sight in freshwater environments such as ponds, lakes, and streams, where ciliates are abundant.

In some angiosperm plants, pollen grains express spikes on their surface that help them stick to the pollinator's body and incrceases the chances of cross-fertlization. Option B. Angiosperm.

Different families among the Angiosperm group produce pollen with spikes on their surface.

This is a strategy developed by these plants to ensure cross-fertilization. Let us remember that pollen is the masculine cell released by the masculine organ of the plant. This cell meets the ovocell and fertilize.

In cross-fertilization, pollinators play an important role since they carry pollen from one plant to another one.

To ensure pollen sticks to the pollinator's body and succesfully get to another flower, Angiosperm developed spikes that help the grain to  cling to the pollinator's body. Once the insect get to the new flower, pollen is deposited, increasing the chances of cross-fertilization.

The blood is collected by the renal veins. Option B is correct.

The efferent arteriole drains blood from the glomerulus, which is a network of capillaries in the kidney that filters waste products from the blood to form urine. The blood that leaves the efferent arteriole enters the renal circulation, where it is collected by the peritubular capillaries and the vasa recta.

These capillary networks surround the renal tubules and loop of Henle in the kidney, where they exchange nutrients, electrolytes, and waste products with the surrounding tissues. From there, the blood is collected by the renal veins, which drain into the inferior vena cava and ultimately return the blood to the heart.

The following are thought to be two key adaptations for running in humans: c. loose shoulders and big buttocks.

Loose shoulders allow for a greater range of motion and rotational movement, which is crucial for maintaining balance while running. The swinging motion of the arms counterbalances the rotation generated by the legs, enhancing stability and preventing energy loss. Additionally, the presence of larger buttock muscles, specifically the gluteus maximus, plays a significant role in running efficiency. These muscles help stabilize the trunk and provide powerful propulsion during each stride, increasing overall running speed and endurance.

While other mentioned adaptations, such as a four-chambered heart, binocular vision, and tetrapod body design, do play essential roles in human evolution and various functions, they are not considered as key adaptations specifically for running. Knees and elbows do contribute to locomotion but are not unique adaptations for running.

If the herbivore population in an ecosystem increased, the Carnivore population would also increase.

It is likely that the size of the ecosystem's carnivore population would also grow if the number of herbivores increased. This is due to the fact that carnivores frequently rely on herbivores as their primary food source in an ecosystem. More carnivores would survive to maturity and breed if there was more food for them to eat, which would result in a greater number of newly born carnivores the following season. The number of carnivores would also begin to decrease when their food supplies ran out if this increase caused a decrease in the herbivore population as a result of increased hunting by the increased number of carnivores.

The process of respiration can be divided into the cellular view to the general (cellular respiration to external respiration). Going from the cellular till the external we have:

1- Cellular respiration

Is the aerobic process by which living cells break down glucose molecules to form energy in the from of ATP, that can be divided in three stages, these are: glycolisis (break of glucose into pyruvate), Citric Acid Cycle (Krebs Cycle), and electron transport chain. In this respiration the cell machinery is responsible for from glucose and oxygen form water and carbon dioxide. All the process is intracellular.

2- Internal respiration

The internal respiration is the process of the exchange of gases between the cells and the tissues (internal environment of the body) by the blood vessels and the circulation od red blood cells that carry these gases (oxygen and carbon dioxide). The path of this process is: nose/mouth, pharynx, larynx, and trachea will have the cells oxigenated, the trachea branches and the bronchi will lead to the lungs when the gases exchanges in the tissue will happen. The red blood cells will do the local capture of the gases and the circulatory system will make those cells go to all the tissues in the body.

3- External respiration

The external respiration is the exchange of gases with the external environment. That process occurs in the lungs where the oxygen diffuses into the blood and carbon dioxide into the alveolar air. The internal and external respiration work together in the overall respiratory process, but one happen in the tissues and the other between external environments.

4- How they work together?

The three process are essential for breathing, that's because they work into different levels of tissue and systemic organization. The cellular is the one in the cells that provide the biochemical reactions necessary to the synthesis and conversion of molecules, being the metabolic basis for the respiration to take place, the internal respiration is responsible to distribute the gases into the tissues to make the cellular step possible, while the external respiration makes possible the exchange outside the tissues levels and makes possible to balance the distribution and concentration of the gases in the body.

The life cycle of trematodes and cestodes requires an intermediate host for its larval stage. This differs from nematodes, as nematodes can have direct life cycles without an intermediate host.

In the case of the dog tapeworm (Dipylidium caninum), the intermediate host is the flea. The adult tapeworm resides in the small intestine of the definitive host, which in this case is the dog or other canids. The adult tapeworm produces proglottids that contain eggs, which are released through the feces of the definitive host.

The eggs of Dipylidium caninum are ingested by flea larvae, typically within the environment where the dog resides. Inside the flea larvae, the eggs hatch, and the released tapeworm larvae (cysticercoids) develop. When the flea larvae mature into adult fleas, they can then transmit the infective tapeworm larvae to the definitive host (dog) when the dog ingests the flea while grooming itself.

Thus, the intermediate host (flea) plays a crucial role in the life cycle of the dog tapeworm by facilitating the development and transmission of the larval stage of the parasite.

To determine the most likely genotypes of Spot's parents, we need to consider the inheritance patterns of coat spotting in dogs.

Coat spotting is typically controlled by a single gene, where the "S" allele represents the spotting allele, and the "s" allele represents the solid coat allele.

Let's evaluate the potential genotypes of Spot's parents based on the given scenarios:

ss X ss:

If both parents have a solid coat and are homozygous for the recessive "s" allele, their genotypes would be ss. In this case, it is highly unlikely that all the puppies would have spotted coats since both parents lack the spotting allele.

Ss X ss:

If one parent is heterozygous with one spotting allele (Ss) and the other parent has a solid coat (ss), the possible genotypes of the parents would be Ss and ss, respectively. In this scenario, the offspring have a 50% chance of inheriting the spotting allele (S) from the heterozygous parent and potentially have a spotted coat.

Ss X Ss:

If both parents are heterozygous for the spotting allele (Ss), the possible genotypes of the parents would be Ss and Ss. In this case, there is a higher likelihood of the puppies inheriting the spotting allele and having spotted coats.

SS X ss:

If one parent has two spotting alleles (SS) and the other parent has a solid coat (ss), the possible genotypes of the parents would be SS and ss. In this scenario, all the puppies would inherit one spotting allele (S) from the homozygous parent, and they are likely to have spotted coats.

Based on these evaluations, the most likely genotypes of Spot's parents to produce all puppies with spotted coats would be:

Option 4: SS X ss, where one parent is homozygous for the spotting allele and the other parent has a solid coat.
