Although bipedalism is unusual, humans are not the only living bipeds. For example, some flightless birds are also bipedal. Identify a living nonprimate animal that is also a biped. Then, compare its bipedalism with our bipedalism. Try to consider how it moves and some of its possible adaptations (such as limb length). Use resources in your classroom, credible online sources, or books to help you if necessary.
Explanation:
In simple terms, the term bipedalism refers to a term used to classify organisms that are equipped and use two legs or limp to walk, stand, jump or run.
One other nonprimate animal that is also a biped is the ostrich. When we compare the bipedalism of an ostrich with our (humans) bipedalism we discover that in terms of
Speed; an ostrich can move faster than an average human, reaching speeds of up to 70 km/h (43 mph).
limb length; its limb length can range from 10 to 16 feet (120 inches to 192 inches) which is far greater than the average length of an adult human's legs.
What other cofactors or cosubstrates does the pyruvate dehydrogenase complex require to function?
Answer:
Pyruvate dehydrogenase (PDH) is a very high molecular weight mitochondrial multienzyme complex.It includes three types of enzymes that need the participation of five coenzymes to develop their activity, three of them catalytic cofactors (TPP, lipoamide, FAD) and two stoichiometric (NAD and CoA). Two enzymes involved in regulating its activity are also part of the enzyme complex.
Explanation:
PDH is a multienzyme complex formed by multiple copies of three catalytic proteins (E1, E2 and E3) and other structural and regulatory (phosphatase, kinase). It requires, in turn, different coenzymes (thiamine, lipoic acid) for its proper functioning. Given its enormous importance at a key point in energy production, it is highly regulated. E1 depends on thiamine pyrophosphate and catalyzes 2 stages: 1) decarboxylation of pyruvate, forming a hydroxyethyl-thiamine-diphosphate intermediate; 2) reductive acetylation of the lipoyl group, covalently linked (amide) to E2. E2 catalyzes the transfer of the acetyl group to CoA (3). E3 regenerates the oxidized lipoyl, transferring its electrons first to FAD and then to NAD.
how does phosphorus enter the phosphorus cycle?
Answer:
Phosphorus moves in a cycle through rocks, water, soil and sediments and organisms. Over time, rain and weathering cause rocks to release phosphate ions and other minerals. This inorganic phosphate is then distributed in soils and water. Plants take up inorganic phosphate from the soil.

Which of the following describes a way that decomposers are important to an ecosystem?
Answer:
Decomposers recycle essential nutrients back into an ecosystem.
Explanation:The decomposers are the small microorganisms which can be found in the soil habitat. These organisms obtain energy by break down of organic matter generated after the death of plants, animals and their residual matter. Through the process of decomposition the decomposers release nutrients such as nitrogen and carbon back to the environment. These nutrients are absorbed by the plants through soil. This way the nutrients are recycled in an ecosystem by decomposers.

Answer:
a.) 12 Newtons
b.) Same Direction
c.) Unbalanced
Explanation:
The system shows 2 individual forces:
A force of 5 N pulling the box LEFT
A force of 7N pushing the box LEFT
Both forces are LEFT, so they have the same direction.
Since the parallel forces both have the same direction, regardless of whether it's a push or pull or what side of the box the force acts upon, the resultant force will be the sum of the two forces in their direction:
Resultant force's magnitude is then: 5N + 7N = 12N
Resultant force's direction: unchanged = LEFT
Since the resultant force's magnitude is not 0, the system is unbalanced.
Which of the following best explains the most likely method by which this antitumor drug works
The platypus bill has a multitude of receptors on it. Initially, researchers thought that the receptors were all mechanoreceptors (i.e. for sensing textures, shapes) because platypus can not smell or detect odors underwater. The scientific community was shocked (pun intended) when it was reported that some of the receptors were actually electroreceptors. Design an experiment to determine if platypus prefer to hunt for prey through mechanoreception or electroreception
Answer:
Experiment: to put insect preys with different textures (but of the same group, for example, moths) into two conditions: 1-pure water and 2-ion-rich water solution. For this experiment, it is important to highlight that the platypus is a semiaquatic mammal that eats insects that fall into the water. Pure water is a poor conductor of electricity, while water containing charged ions (and also impurities) is a good conductor of electricity. In consequence, if the platypus prefers to hunt through electroreception, it is expected that the ability for hunting will be better in an ion-rich water solution than in pure water. Second, if the platypus prefers to hunt through mechanoreception, it is expected that the ability for hunting will vary depending on the type of texture that exhibits insect preys (in this case, moths).
Explanation:
Mechanoreception can be defined as the ability to detect and respond to a stimulus by using sensory cells (neurons) that respond to mechanical pressure and/or distortion, while electroreception is the ability to respond to electrical stimuli, thereby detecting weak electric fields in water. In the experiment above described it is possible to determine the hunting preferences under differential electroreception/mechanoreception conditions. Statistical scores such as p-value can be used to determine the outcome of the experiment.

this is you're answer please give me thanks
Answer:
In cells, oxygen is needed for aerobic respiration, which allows for the extraction of energy from ingested foods. Thus supplemental oxygen at home and in hospitals is vital for those with breathing disorders such as emphysema.
Compressed oxygen tanks are used by mountaineers at high elevations to counteract the decreased O2 pressure at these altitudes.
Supplemental oxygen is needed for surgical patients intentionally rendered paralyzed for medical procedures, in which "heart-lung machines" keep their vital functions going.
Oxygen can be used as a sterilizing agent to kill certain anaerobic bacteria that are killed by sufficient exposure to the gas.
Industrial Uses of Oxygen:
Oxygen is needed for the reaction that converts carbon to carbon dioxide gas in steel working, which takes place under high temperatures in a blast furnace. The carbon dioxide produced allows for the reduction of iron oxides into more pure iron compounds.
Oxygen is used in other applications involving metal and requiring high temperatures, such as welding torches.
Aerospace Uses of Oxygen:
In liquid form, oxygen is used widely as an oxidizing agent for use in missiles and rockets, where it reacts with liquid hydrogen to produce the terrific thrust needed for take-off. Astronaut spacesuits include a nearly pure form of oxygen.
Oxygen is used to degrade hydrocarbon compounds, which are broken apart by heating them. This is used to create combustion that usually liberates water and carbon dioxide, but can also produce the hydrocarbons acetylene, propylene and ethylene.
Oxygen is used in sewage-treatment and water-purification plants. It is forced through water to increase the production of bacteria that metabolize waste products in the water.
Oxygen gas (O2) is needed to produce energy in things not linked to an electrical supply of their own, such as generators and vehicles (e.g., ships, airplanes and cars).

Why is the hydrolysis of water required for photosynthesis?
Hydrolysis is a chemical process in which a water molecule is inserted.
In light-based reaction, which occurs in the thylakoid layer, chlorophyll absorbs energy from the sun and converts it into chemical energy through water. Light-dependent reactions release oxygen to water hydrolysis as a by-product.
Hope it helps!
Water is one of the most important components of photosynthesis. The hydrolysis of water is required to provide the Electrons and protons( Hydrogen ions) in photosynthesis.
Light Reaction photosynthesis:
It is the phase in which plant cells produce NADPH and ATP via the energy of the electron transport chain.
In this phase,
The water hydrolyzes to produce, electrons and Hydrogen Ion. Electrons move in from protein to protein and release their energy.This energy is used to pump the more hydrogen ion into the thalakoid lumen. The final electron is used to reduce the NADP molecule.Therefore, the hydrolysis of water is required to provide the Electrons and protons( Hydrogen ions) in photosynthesis.

Meerkats live together in groups to help raise and protect their offspring. Meerkat pups are most vulnerable when they are away from their burrow foraging for food. Adult meerkats exhibit sentinel behavior, standing upright and making alarm calls to warn other members in the group that predators are nearby. In a study of meerkat behaviors, scientists observed meerkat foraging groups and recorded the presence or absence of pups along with the frequency of adult sentinel behavior. The scientists determined that sentinel behavior increased when pups were present in the foraging group. Which of the following correctly identifies the dependent and independent variables in the described study? A. The frequency of sentinel behavior is the independent variable, and the presence of pups is the dependent variable. B. The presence of pups is the independent variable, and the frequency of sentinel behavior is the dependent variable. C. The number of predators is the independent variable, and the presence of pups is the dependent variable. D. The distance from the burrow is the independent variable, and the number of predators is the dependent variable.
Answer:
The correct answer is - option B. The presence of pups is the independent variable, and the frequency of sentinel behavior is the dependent variable.
Explanation:
The independent variable in a study or experiment is a variable that is subject to change or manipulated to see the effect on the result of the study by influencing the dependent variable. In this study, the independent variable that is manipulated is the presence of the pups to see what is led to the behavior of meerkats.
The dependent variable is a variable that is influenced in a study by the independent variable and led to the result of the study as the frequency of sentinel behavior is influenced by the presence of the pups so the dependent variable here is the frequency of sentinel behavior.
