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.

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).

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.

Answer:

Decomposers recycle essential nutrients back into an ecosystem.

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:

The correct answer is - neurulation

Explanation:

The neural groove is a groove of the neural plate which is a thick plate that is enclosed by the neural folds of an embryo. The neural grove forms the neural tube which expands and develops into the spinal cord and brain.

The development of the neural grove is taken place during the process known as neurulation which is characterized by all characteristic development related to the neural groove and ventricular system.

Answer:

4 grams

Explanation:

If in an experiment, we have 4g of reactants, the mass of the products will also be 4g.

This is in compliance with the law of conservation of mass in a chemical reaction.

According to this law,

  "in a chemical reaction, matter is neither created nor destroyed but changed from one form to another".

If:

      A + B →  C

         4g        4g

mass of A and B must be equal to the mass of the product according to the law of conservation of mass.

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.

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.

Answer:outer core

Explanation:

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.

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.
