A student placed a rock in a graduated cylinder containing water causing the water level in the cylinder to increase by 20 mL. This increase represents the rocks

Answers

Answer 1

This growth corresponds to the volume of the rocks. According to the displacement caused by the boulder, the water in the grade cylinder rises.

What features does water have?

Water molecules have a twisted, polar shape with partial p-sides on the hydrogen atoms and partial electrostatic force on the oxygen atoms. This is due to oxygen's greater electronegative nature, which draws electrons more potently than hydrogen does. Water is a fantastic solvent.

Why are the water so important?

A water molecule is consisting of two hydrogen bonds bound to a carbon atom and has a bend overall structure. This is due to the fact that in addition to bonding with both hydrogen bond, the oxygen molecule also carries 2 sets of lone electrons. maintain the same temperature.

Data was collected concerning Galapagos bird beak size over time. There are several species finches, and they are also known as

Darwin's Finches. These finches share the same habits and characteristics except for one; they all have different shaped and sized

beaks. The differences in their beaks might be the most important aspect of their survival. Around 1977, there was a huge drop in

finches with small beaks while there was a great increase in large-beaked birds. How can you explain this?

A)

The small-beaked finches were prey for larger animals.

B)

The large-beaked birds preyed on the small-beaked birds.

Available food changed and the small beaked birds could not readily adapt.

D)

Competition for food favored large beaks; the small beaked birds died off.

Answers

The struggle among Darwin's Finches, which is especially fierce during dry spells due to food scarcity, benefits those who are most adapted to their environment, according to the best conclusion.

Different finches species have nutritional specializations that are characterized by variations in their beaks due to diverse ecological settings on the same island.

Additionally, it has been demonstrated that finches that live in highly planted zones have a distinct call than those that reside in less vegetated areas, expanding their spectrum of mating calls.

A couple that belongs to the same milieu (environment) is more likely to be discovered as a result of this event, and it is from that point that the stabilization of genetic traits unique to the ecological environment occurs.

With this information, we can conclude that competition, which is particularly severe in periods of drought due to food shortages, favors the individuals most adapted to their environment. Because they have a greater chance of survival and, therefore, of reproduction, their particular genetic characteristics tend to be passed on to subsequent generations.

why does breathing become faster during exercise​

Answers

Explanation:

When you exercise and your muscles work harder, your body uses more oxygen and produces more carbon dioxide. To cope with this extra demand, your breathing has to increase from about 15 times a minute (12 litres of air) when you are resting, up to about 40–60 times a minute (100 litres of air) during exercise.

Your body needs more oxygen and creates more carbon dioxide while you exercise because your muscles are working harder.

A molecule that can be used as a molecular clock has a neutral mutation rate of one mutation per 40 million years. How many years ago did two species share a common ancestor if the molecules found in these two species differ by a total of eight mutations

Answers

The two species must have shared a common ancestor 320 million years ago, since the neutral mutation rate of the molecular clock is one mutation per 40 million years and the two species differ by a total of eight mutations.

A molecular clock is a tool used by scientists to estimate the time since two species have shared a common ancestor. This is done by measuring the number of genetic differences, or mutations, between the two species. The molecular clock is based on the assumption that the mutation rate is constant.

In this case, we know that the neutral mutation rate of the molecule being used as a molecular clock is one mutation per 40 million years. This means that for two species to have a difference of eight mutations, it must have been at least 320 million years ago that they shared a common ancestor.

To arrive at this conclusion, we can use the following formula:

Number of mutations × Neutral mutation rate = Time since common ancestor

In this case, 8 mutations × 40 million years = 320 million years. This means that two species must have shared a common ancestor at least 320 million years ago for them to have a difference of eight mutations.

The molecular clock can be a powerful tool for scientists to estimate the time since two species have shared a common ancestor. In this case, the neutral mutation rate of the molecule was known and used to calculate that two species must have shared a common ancestor at least 320 million years ago.

What is the difference between cellular respiration and getting energy from a log by burning it?

Answers

The stored chemical energy is eventually released during cellular respiration through a sequence of enzyme-aided processes. When a log burns, chemical energy that has been stored is swiftly released as heat and light.

     

Living cells need respiration, a biological process, to release energy. A chemical reaction called combustion takes place outside of living organisms or cells. A controlled biological process, respiration. It is impossible to control combustion. When there is oxygen present, substances undergo a chemical reaction known as burning, which produces significant amounts of heat and light. Similarities between burning and respiration For the creation of energy, both processes need oxygen. As a byproduct, they emit carbon dioxide. The metabolic process known as respiration is when an organism obtains energy from the breakdown of glucose molecules in the form of ATP molecules.

Yes, both arrangements of chromosomes in late prophase I are equally likely during the formation of tetrads. This is because, during meiosis, the homologous chromosomes replicate and then line up in pairs, known as tetrads.

During this process, the chromosomes can line up in any order, as long as the homologous chromosomes are paired together. Since the two arrangements of chromosomes in late prophase I consist of homologous chromosomes, they are both equally likely during the formation of tetrads.

How is most ATP formed during respiration?

Answers

Most of the ATP produced by aerobic cellular respiration is made by oxidative phosphorylation

Oxidative phosphorylation is responsible for the majority of the ATP generated by aerobic cellular respiration. Protons are pumped through a membrane to produce a chemiosmotic potential using the energy released. Then, ATP synthase is engaged by this potential to synthesis ATP from ADP and a phosphate group. During aerobic respiration, glucose and oxygen combine to produce ATP, which the cell can utilise. As products, water and carbon dioxide are produced. In the general equation for aerobic cellular respiration, glucose and oxygen combine to create ATP. Oxidative phosphorylation is the biochemical cycle that generates a most net ATP per molecule of glucose.

The current neonatal resuscitation guidelines recommend to start chest compression in a newborn infant if the heart rate remains <60 beats per minute despite adequate ventilation for 60 s .

A small percentage (less than 10%) of newborn babies need active resuscitative measures in order to establish a loud cry or consistent breathing, keep their heart rates over 100 beats per minute (bpm), and acquire acceptable color and tone.

The establishment of proper ventilation has to be your top priority. If stimulation does not result in the prompt commencement of spontaneous respirations or the heart rate is below 100 bpm, give assisted ventilation while paying close attention to oxygen delivery, inspiratory time, and effectiveness as determined by chest rise.

To obtain roughly 90 compressions and 30 breaths per minute, time chest compressions with ventilations at a 3:1 ratio at a rate of 120 events per minute.
