Some plants have specialized tube-like structures that transport nutrients, minerals, and water. Water and dissolved ions are transported by xylem tubes. Phloem tubes transport nutrients. The picture below is a cross-section of a celery stalk with the xylem showing in the red bundles . In which direction would the water be moving in this celery stalk?A) The water would be flowing upwards towards the leaves.B) The water would be flowing downwards towards through the stem and to the roots.

All of the options are correct.

The products of one process are the reactants of the other. We can conclude that cellular respiration is the direct opposite of photosynthesis.

We have to consider that capillaries are blood vessels where our blood can move throughout our whole bodies nourishing each tissue with oxygen, but also carrying other nutrients, such as glucose to perform metabolic processes, like cellular respiration, so we can say that capillaries both oxygen and reabsorb nutrients. This can be done because the cells after performing those processes, can send out those products present in the intracellular media outside the cells via vesicles done by the Golgi apparatus. Eventually, these materials will be conducted through specialized capillaries known as lymphatic vessels, suspended in a fluid known as lymph, which is a liquid our bodies produce to carry out these substances, such as proteins and fats, but also white blood cells. And in this metabolic process of nourishment, enzymes produced in the pancreas but also in the small intestine, such as lactase, and sucrase will be crucial to catabolize the aliments that will give start to these set of reactions. This can be graphically represented as the following picture does, especially focusing in the stomach, the pancreas, and the small digestive intestine:

The type of natural selection that a single average phenotype is favored is the stabilizing slection (d), since an single average phenotype is favored being the individual trait the most present in the population.

An observational study means that the researchers observe the data without changing anything, while in an experimental study the researchers change something to observe the effects of what they changed.

A survey of the preferred food of the guest is not changing anything, just asking for preferences, so this is an observational study.

During a chemical reaction the total mass remains the same. This means that the mass of the consumed reactants equals the mass of the created products. The number of atoms also remains the same but the molecules change.

Many meals have in their composition starch, a molecule that is formed by glucose monomers. When the human body uses glucose it transformes this carbon based molecule into water, carbon dioxide and energy.

The chemical reaction of this process is the following:

As we can see the number of each atom that conforms the reactants equal those of the products:

in total (both in the reactats and the products):

6 carbon atoms

12 hidrogen atoms

18 oxigen atoms

In this reaction glucose and carbon dioxide are both carbon based molecules

The correct option is C. "Sprouting seeds and growing roots can cause rocks to break." When seeds sprout and their roots start to develop, they start a complex chemical process. This process along with their physical increase is capable of weathering, specially if we consider this in trees which have deep roots.

Answer:

True

Explanation:

Yes the statement is true since the air flows from higher pressure to lower pressure and the rate of flow is directly proportional to pressure difference.

So increase in pressure difference will cause increase in rate of flow of air which means the winds will ne stronger.

In this case, we need to remember how we detect an optimum in enzyme activity. As the reaction accelerates and reaches the slope the optimum has been reached, when conditions keep changing after the optimum, the curve descends.

2a, here we have a thermophilous bacteria that lives at a high temperature so is natural that the optimum of an enzyme of this bacteria be at high temperatures as is the case of curve 3.

b. For this curve we have a slope around 30°C so this is the optimum temperature.

c. Here the curve is generated with a pH range, and the dynamics is the same that with temperature. The human stomach has a pH around 2, so the most likely slope that corresponds with human enzyme is curve 4.

In the diagram, part 11 corresponds to the pulmonary alveoli, which is where the gas exchange occurs, given that they are surrounded by capillaries and the oxygen and carbon dioxide can diffuse between the capillaries and the alveoli.

So, capillaries are the part of the circulatory system that interacts with alveoli.

The types of respiration in humans are:

• Pulmonary ventilation,: the process of, taking air in and out of the lungs, (inhalation and exhalation). ,This involves the nasal cavity, pharynx, larynx, trachea, bronchi, bronchioles, alveoli, and lungs, as well as the diaphragm (structures 1 to 11)

• External respiration ,is the ,gas exchange, that, occurs in the alveoli (structure 11),, where the carbon dioxide diffuses from the blood cells in the capillaries to the alveoli, and the oxygen goes from the alveoli to the capillaries.

• Internal respiration ,is the exchange of oxygen and carbon dioxide that occurs ,between the blood cells and all the other cells in the body,.

• Cellular respiration, is the set of metabolic reactions that takes place in the mitochondria of each cell to break glucose to obtain energy in the form of ATP, which requires the presence of oxygen.

Parkinson's disease occurs due to the lower level of dopamine in brain. It causes unnecessary tremors that originate especially from the region called thalamus. Therefore, thalamus is the correct answer.

In Parkinson's disease the tremors are different from any other kind of tremors, they are especially known as essential tremors. It is the disorder that causes the rhythmic contraction of muscles in an uncontrolled way, causing difficulty to the person in performing simple tasks.

There are some possibilities that can cause Parkinson's disease such as - Mercury poisoning, anxiety disorder, any kind of brain disease. Even though, there are evidence that 60 - 80% of cases are due to sudden reduction in the dopamine producing cells.

Parkinson's can be diagnosed by observing the person's symptoms. A neurologist can give the most correct diagnosis for Parkinson's. It has tremors in many places of the body, but most commonly affected areas are- hand and fingers, mouth or tongue, legs.

Growing urbanization can lead to deforestation mainly in two ways. When people move from rural areas to the cities they tend to consume in a higher rate, because the ways of living in cities are different from those in rural areas. For people to consume more and to attend their urban needs (which includes electricity, piped water, constructions, etc), there is a need to extract more materials from nature that will be used in the processes that will make those things available. The second major impact of urbanization on deforestation is that the cities need to grow, and they grow taking land from natural forests and such. So, deforestation occurs to give place to the constructions and infrastructure needed in urban cities.

DNA replication is the process by which new copies of DNA are produced, and it normally occurs prior to cell division.

DNA is made of two complementary chains or strands, and during replication, each of these strands is used as a template for the synthesis of a new strand. This means that each molecule of DNA produced in replication has one "old" strand and one "new" strand, and is because of this that replication is considered a semi-conservative process.

Given that DNA has a double helix structure, this helix must be unwound to allow replication to occur. This unwinding is performed by an enzyme called helicase, and after that, the DNA polymerase proceeds to add the complementary nucleotides to each DNA strand.

Carrier proteins moving from low to high concentration requires the use of energy to transport substances. This is called active transport and uses transmembrane proteins, pumps and vesicles, which is cell membrane.

Active transport is the type of transport where molecules are transported using energy. This energy can be in the form of ATP or the energy released during co-transport. In active transport, the solute is transported against the concentration gradient, i.e., from lower to higher concentration.

Vesicles are the single membranous self-made structures. These are actually small spherical buds formed due to the pinching off of the cell membrane. They are actively involved in transport across various organelles of the cell.
