Answer:

The higher the velocity of a fluid (liquid or gas), the lower the pressure it exerts. This is called Bernoulli’s Principle. Fluid pressure is caused by the random motion of the fluid molecules. When the fluid speeds up, some of the energy from that random motion is used to move faster in the fluid’s direction of motion.

Answer and Explanation:

During the whole biota history, there occurred extinctions due to different reasons.  

During the Cretaceous, which took place between 145-65 million years ago, there occurred a massive extinction that eliminated most of the species on the Earth. Many of the characteristic groups of this period were affected. Dinosaurs, Plesiosaurs, Ammonites, Tricodonts, Cycas, Gynkgos, Conifers, the recent angiosperms, birds, and mammals.  

The extinction was caused by the volcanic eruptions, and the unusual fall of many different asteroids, which caused important changes on the Earth´s surface. The consequent climatic change was what ended affecting all the species directly. The extinction was gradual, although it occurred in a short geological lapse of time.

Overview of answer:

-First, your digestive system is involved in the hunger pains you feel because your stomach is empty and your body needs more energy.

(-Since you are alive and breathing, your respiratory system is also involved.)

-Getting up involved the muscular and skeletal systems, which allow movement and bodily structure, and the nervous system, which commands the muscles and bones to move.

-Eating and drinking involves the digestive system again as saliva and enzymes break down the food travelling from the mouth to the stomach.

Explanation:

I think that is all involved but there may be more depending on how you look at it. Hope this helps! :)

Digestive system is involved in the hunger pains you feel because your stomach is empty and your body needs more energy.

The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion. Digestion involves the breakdown of food into smaller and smaller components.

he digestive system breaks down food into nutrients such as carbohydrates, fats and proteins.

They can then be absorbed into the bloodstream so the body can use them for energy, growth and repair. Unused materials are discarded as faeces.

Answer:

El protozoo se encogerá mientras que las algas no se hincharán ni encogerán.

Explicación:

El protozoo se encogerá debido a la condición hipertónica del medio porque todo el líquido presente en el cuerpo sale al exterior debido a una mayor concentración de solutos fuera de la célula, mientras que por otro lado, para un alga es isotónico, lo que significa que no hay hinchazón. o se produce un encogimiento en el cuerpo de las algas debido a la solución salina del medio.

Answer:

By crossing plants with purple flowers, dominant, with plants with white flowers the offspring will be 100% purple because all the offspring will receive at least one dominant allele.

Explanation:

The crossing of two plants of pure line, one dominant and one recessive, for a trait —the color of the flowers— will produce a hybrid offspring which will express the dominant trait in its phenotype.

Parental generation:

Cross: PP X pp

Punnett Square :

Alleles       P       P

p              Pp     Pp

p             Pp     Pp

Offspring: 100% Plants whose phenotype is purple flowers and Pp genotype.

According to this, the descendants will be 100% plants with purple flowers, hybrids, since all the offspring received at least one dominant allele.

Answer:

supplies energy and fiber

Explanation:

Carbohydrates are what provides the body with fast, immediate energy, vs fats which are long term energy.

Carbohydrates are the source of energy thus the molecules that are used here are the energy molecules in the process of food metabolism as well.

It is the whole grains, fruits and vegetables.

Along with the  proteins and fats there are  carbohydrates that are one of  these three main nutrients that are in the foods and drinks. Our body is breaking  down into the carbohydrates into the glucose. Glucose or blood sugar is main source of the  energy for our body's cells, tissues and organs.

The primary role of  the carbohydrates is to supply out the energy to  the all  of the cells in body.  Many cells are  preferred as the  glucose that are a source of the  energy where the other compounds as the fatty acids. Certain cells such as red blood cells are only there to produce out  cellular energy out  from glucose.

Answer:

Nitrogenous base

Explanation:

Phosphate and deoxyribose create the "backbone" of a DNA molecule.

Think of the molecule as a ladder.

These(deoxyribose and phosphate) are the sides of the latter.

The nitrogenous bases(A,G,C,T) are the rungs of the ladder.

As the arrow points to the "rung" of the ladder, that means it is a nitrogenous base.

Answer:

phototropism

Explanation:

Auxins promote stem elongation, inhibit growth of lateral buds (maintains apical dominance). They are produced in the stem, buds, and root tips. ... This produces a curving of the plant stem tip toward the light, a plant movement known as phototropism. Auxin also plays a role in maintaining apical dominance.

Phototropism made possible by a high concentration of auxins in a plant's shoot and root

The correct answer is C

A plant can maximize photosynthetic light absorption in the aerial portion and water and nutrient uptake in the roots by using phototropism, or the differential cell elongation displayed by a plant organ in response to directed blue light.

What occurs during phototropism?

Positive phototropism, or growing toward the light, is the term for how a plant stem reacts to light. A negative phototropism, or root growth away from the light, is the term used to describe how a plant root reacts to light.

Answer:

Water separates polar molecules from each other by forming hydrogen bonds.

Explanation:

A polar molecule is a molecule in which the distribution of electrons between the covalently bonded atoms is not even. This means that one end of the bond is slightly more positively charged, while the other end is slightly more negatively charged.

An example of a polar molecule is a molecule of water (H2O). Substances with similar chemical characteristics dissolve in each other. This means that polar molecules will dissolve in water. The partially negative part of a water molecule will interact with the partially positive part of another polar molecule. This results in the formation of hydrogen bonds, which occur when a hydrogen atom is located between a pair of other atoms that have a high affinity for electrons.

Answer:Acids and bases In the human body, both blood and the cytosol (watery goo) inside of cells have pH values close to neutral. ... A base, in contrast, raises pH by providing hydroxide (OH −start superscript, minus, end superscript) or another ion or molecule that scoops up hydrogen ions and removes them from solution.

The correct answers are

The formation of foam is a process when the small bubbles of the gas get trapped inside a solid or a liquid a form is made and gets made by the tapping of millions of small bubbles and can be seen in marshmallows. The process of foam formation is thus through dispersed medium and in general gas is present.

The foam is thus evidence that respiration, is taking place as carbon dioxide is a product of respiration.

It is critical that we sustain an optimal temperature for our body's enzymes. When it gets too hot, our enzymes denature and become inactive/lost their function. If the temperature is too low, the enzymes will become ineffective.

Homeostasis is the state of constant internal, physical, and chemical assumption is supported by living systems in biology.

This is the state of the organism's optimal functioning, and it includes many variables, such as core temperature as well as fluid balance, getting kept within certain pre-set limits.

Enzymes can only function when the body's temperature remains constant. As a result, homeostasis becomes an important part of the body's metabolism.

Homeostasis maintains optimal conditions for enzyme action and all cell functions throughout the body.

It is the preservation of a constant internal environment in the face of changing internal and external conditions. These include blood glucose concentration control in the human body.

Thus, having an optimum temperature is essential in functioning of enzymes.
