Which hormone helps prevent excessive drops in blood pressure/volume? Not B.

Answer:

nitrogen fixation

Explanation:

Nitrogen in the atmosphere can be transformed into a plant-usable form, a process called nitrogen fixation, by lightning. Each bolt of lightning carries electrical energy that is powerful enough to break the strong bonds of the nitrogen molecule in the atmosphere.

Answer: Well, cytokines happens after mitosis so you wouldn't see the daughter cells dividing yet. 

Explanation: Onion root-tip cells divide once every 24 hours, or roughly two hours after sunrise, and go through a cell cycle that lasts for about 24 hours. Therefore, in order to harvest the greatest amount of proliferating cells, water-grown roots should only be removed at that time.

pH: Each enzyme has an optimum pH range. Changing the pH outside of this range will slow enzyme activity. Extreme pH values can cause enzymes to denature. Enzyme concentration: Increasing enzyme concentration will speed up the reaction, as long as there is substrate available to bind to.

Answer:

7>ph<14

Explanation:

if ph is 7 then its neutral, if ph lower than 7 and higher than 0 its acidic, if it's higher than 7 and lower than 14 its basic.

Answer: Poison Dart Frog, Jaguar, Sloths

Explanation:

The energy transfer that occurred between the lanuch of a rocket and its continuing flight out of the atmosphere is that the chemical energy stored in the fuel of the rocket is transformed into heat energy.

Energy transfer is defined as the process by which a form of energy is being transformed to another form without destruction of the energy.

There are various ways by which energy can be transferred and it includes the following:

When a rocket is being launched, the chemical energy in its fuel would be converted to another form of energy called heat energy through the actions of mechanical and heating processes of the rocket engine.

If there is no skeletal system, the person will not be able to move at all or breathe.

The skeletal system not only serves as a support and lever for the movements of the body, it also serves as protection for the internal organs so that in the face of an impact it does not cause them any damage.

Also the thorax, apart from supporting all the thoracic organs and protecting them, will have a function in breathing so that they inflate while the diaphragm contracts. If all this is not done simultaneously, breathing will not be possible and this will be incompatible with life.

As for the skull, there will not be the correct separation of nerves and brain fluids and this will not be sustainable for life either, since a certain support is needed that gives the cerebrospinal fluid to the structures of the central nervous system and the intracranial pressure that also occurs.

Therefore, we can confirm that if there is no skeletal system, the person will not be able to move at all or breathe.

Entry-level encyclopedia vocabulary An ecosystem is a region where a bubble of life is created by plants, animals, and other organisms interacting with the weather, environment, and other factors. Abiotic variables, or nonliving components, coexist with biotic components in ecosystems.

The interactions between species and the environment produce a natural ecosystem. An ocean, for instance, is categorized as a marine ecosystem since it contains algae, consumers, and decomposers. This kind of ecosystem goes through a cycle that starts with algae producing energy through photosynthesis.

The eruption was preceded by a two-month series of earthquakes and steam-venting episodes produced by an injection of magma at shallow depth below the mountain.

A wave of diminishing pressure traveled down the volcanic conduit until it reached the underground magma reservoir. The magma reservoir then started to rise, produce bubbles (degas), and erupt explosively, which drove a Plinian eruption that lasted for 9 hours. Mount St. Helens's summit crater saw a steam-blast eruption recently.

An injection of magma at a shallow depth below the mountain caused an enormous bulge and a fracture system on Mount St. Helens' north slope before the eruption, which was preceded by a series of earthquakes and steam-venting episodes that lasted for two months.

Nitrous oxide, neon, helium, methane, xenon, ozone, iodine, carbon monoxide, and ammonia are also present. As the most prevalent element in the Earth's atmosphere, it is also the primary ingredient of all biological stuff.

Herbage provided more dry matter and energy to tortoises than grass. Although herbage provided more N and retained more of it than grass, amino acid compositions and actual N digestibilities were comparable between diets. Herbage had more Ca than grass, particularly in respect to P (Ca:P 14.5 vs. 1.9), although this was mitigated by the herbage's decreased absorption of Ca. K intakes from herbage were higher than from grass, and this was related to the digestive loss of Mg from herbage. The low Na concentration of both forages resulted in net Na losses.

It is possible to have a warning system for volcanoes because most volcanoes issue warnings before erupting.

As a volcanologist, certain volcanoes on the map will be monitored more than others because some volcanoes are more explosive than the others.

Monitoring volcanoes enables volcanologist to understand its activities during an unrest through seismicity, deformation and degassing. Some volcanoes are explosive while others are not so the volcanologist has to monitor the type of magma that flows from it.

The volcanologist also uses the map as an indicator to know when any volcano is scheduled to erupt because some volcanoes provide warnings before eruption.

Answer:

By examining the pace of change in the gases released, the rate of change in seismic activity, the rate of change in ground deformation, and other variables, a volcanic eruption can be predicted. These are early warning indicators of an eruption. Volcanologists should concentrate on Kilauea and Shishaldin when studying the map because these two volcanoes are at the watch alert level and are more likely to erupt.

The percentage of offspring that will have yellow fruit if a homozygous dominant (RR) fruit is crossed with a heterozygous (Rr) fruit is 0%.

A punnet square is the graphical representation used to determine the probability of an offspring expressing a particular genotype.

According to this question, in tomato plants, red fruit (R) is said to be dominant to yellow fruit (r). This means that the homozygous dominant genotype will be RR while the heterozygous fruit will have a genotype of Rr.

Hence, if a cross between RR (red) × Rr (red) occurs, the following offsprings will be produced:

Based on the above genotype of the offsprings, it can be observed that none of them have a yellow fruit phenotype, hence, the percentage will be 0%.
