What are the atomic masses of
protons, neutrons, and electrons?

Answer:

1. __pulse pressure_ is the calculated as systolic pressure minus diastolic pressure and indicates the additional pressure the artery when ventricles are contracting.

2. _systolic pressure_ is in the arteries at the peak of ventricular while

3. __diastolic pressure_ is the pressure in arteries during ventricular relaxation.

4. _MAP_ can be calculated as diastolic pressure plus one-third the pulse pressure because the ventricles spend more time in diastole.

5. __blood pressure_ is the force per unit area exerted a blood vessel wall by the blood, and it fluctuates with the alternating contraction and relaxation of ventricles

Explanation:

To study arterial pressure, two values are taken:

- Systolic pressure, SP, is the maximum pressure exerted by the heart while beating

- Diastolic pressure, DP, is the amount of pressure in the arteries between beats

Pulse Pressure, PP, refers to the difference between systolic arterial pressure and diastolic arterial pressure.  

PP = SP - DP

PP is an index of arterial distensibility. The main determinants for PP in each ventricular ejection are the cardiac output, heart rate, stiffness of large-caliber arteries, and the early reflection wave of the heartbeat. PP is a measure that reflects the vascular elasticity of the arterial wall.  

Generally speaking,  

Mean Arterial pressure, MAP, can be defined as the mean pressure during the cardiac cycle. It is usually a little bit lower than the mean between SP and DP.  

Blood pressure is the strength applied by the blood against the vessel walls as it flows.  This pressure is determined by the blood pumping force and its volume, and by the vessel size and flexibility.

A micromolecule is a small molecule with a molecular weight of less than 1000 daltons, while a macromolecule is a large molecule with a molecular weight of more than 1000 daltons.

Micromolecules are composed of a small number of atoms and include compounds such as sugars, amino acids, and nucleotides. They can be easily dissolved in water and do not require much energy to break apart. They also tend to be relatively stable and do not typically undergo significant changes in their structure.

Macromolecules, on the other hand, are composed of a large number of atoms and include compounds such as proteins, carbohydrates, and nucleic acids. They tend to be insoluble in water and require a significant amount of energy to break apart. They also tend to be less stable and are more prone to undergoing changes in their structure.

Another way to distinguish micromolecules and macromolecules is by looking at their chemical properties. Micromolecules are typically organic compounds, while macromolecules are typically polymers, composed of repeating units.

Therefore, the main difference between micromolecules and macromolecules is their size, macromolecules are larger than micromolecules, and their chemical properties, micromolecules are small organic compounds, while macromolecules are large polymers.

Answer:

answer is 10 cause formula is t= 1/f

The period of a wave traveling at a rate of 0.100 Hz is 10 sec.

A wave is a propagating dynamic disturbance of one or more quantities in physics, mathematics, and related fields.

Periodic waves occur when quantities oscillate repeatedly about an equilibrium value at some frequency.

A wave is a disturbance in a medium that transfers energy and momentum from one point to another.

The orientation of progression of the individual particles of the medium relative to the direction that the waves travel is one way to categorize waves.

This classification of waves results in three distinct categories: transverse waves, longitudinal waves, and surface waves.

We know that,

Frequency = 1/time

Here it is given that, frequency = 0.10 Hz.

So,

f = 1/t

0.1 = 1/t

t = 10 secs

Thus, the period is 10 sec.

The 3 postulates of the Cell Theory are:

-Every living being is composed of cells, therefore they are the minimal functional unit of life, in their different levels of structural complexity. One single

cell is enough to make up an organism, but also multiple cells can organize in colonies or in a single organism, diversifying their functions and having a margin of independence quite elevated as a whole.

-All of the vital functions of living organisms have a place inside the cell, through biochemical processes and are controlled by substances that the cell secrete. Each cell operates as a unique open system, that exchanges matter, and energy with its environment in a controlled way. Moreover, in each cell of an organism are present the same vital functions that are in the organism itself, that is birth, growth, reproduction, and death.

-Every existing cell comes from a previous cell, by cell division, or by formation from stem cells.

The unknown parent's genotype in the dihybrid cross is likely GgPp. This genotype would result in a 1:1 phenotypic ratio of green pod-purple flower to yellow pod-purple flower offspring.

In a dihybrid cross, we consider two independent traits. In this case, the traits are pod color (green or yellow) and flower color (purple). The known parent's genotype is GgPp, where G represents the dominant allele for green pod color, g represents the recessive allele for yellow pod color, P represents the dominant allele for purple flower color, and p represents the recessive allele for non-purple (white) flower color.

Therefore, the genotype of the unknown parent is likely GgPp, which produces the desired 1:1 phenotypic ratio of green pod-purple flower to yellow pod-purple flower in the offspring.

Your human anatomy is created and maintained by your DNA. Your unique physical characteristics are a result of your genes, which are parts of your DNA. DNA segments known as genes carry instructions for constructing proteins that influence physiology and support the development of particular traits or behaviors. Gene variations known as alleles vary according to the nucleotide base that is present at a specific chromosomal position. The genotype of a person consists of a set of alleles. Chromosomes, which resemble thread-like structures and house the molecule, are found in the nucleus of every cell. The DNA of each chromosome is tightly wrapped.

Mammals' skulls, as well as their dentition, may provide us with information about their diet. The skull of a mammal that lacks sharp canine teeth and has broad, flat molars, is likely to be herbivorous.

Furthermore, the molars' flat shape indicates that the mammal is probably a grazer that consumes grass or tough vegetation. In contrast to carnivorous mammals that use their sharp, pointed canine teeth to tear flesh and their molars to shear meat into smaller pieces, herbivorous mammals use their flat, wide molars to grind and crush tough vegetation.

The molars are often covered in ridges and crests, which increase the surface area of the teeth, allowing them to break down the fibrous plant material into smaller pieces that can be more easily digested. The molars are frequently continually expanding throughout the animal's life, allowing the animal to continue to grind up vegetation even as its teeth become worn down due to constant use.

The skull and teeth of a mammal provide important clues about its lifestyle, feeding habits, and ecology, and scientists can learn a lot about past animals by studying their bones.

The earliest land plants, such as liverworts, mosses, and ferns, were successful in the humid and moist ancient environment because they were well-adapted to absorb and retain water in their tissues. These plants have simple root systems and lack vascular tissue, which helps them to absorb water and nutrients from their surroundings more efficiently. They also have a high surface area to volume ratio, which allows them to absorb water through their leaves and stems as well.

However, these plants are not well-suited to thrive in drier climates because they lack the specialized structures that allow them to conserve water and protect themselves from desiccation. They also have limited capabilities for seed production and dispersal, which can make it difficult for them to colonize and establish themselves in new environments.

Angiosperms and gymnosperms, on the other hand, are more successful in drier climates because they have developed specialized structures and strategies to conserve water and protect themselves from desiccation. These include features such as thick, waxy cuticles on their leaves, stomata that can open and close to regulate water loss, and seed production and dispersal mechanisms that allow them to colonize new environments more effectively. These adaptations allow angiosperms and gymnosperms to thrive in a wider range of environments, including those with drier climates.

Answer: buuu

Explanation:

The two pieces of evidence that support the theory of the expanding universe are the red shift of light from distant stars and the existence of cosmic background radiation.

The correct answer is option B.

1. Red shift of light from distant stars: The observation of redshift in the light coming from distant galaxies provides evidence for the expansion of the universe. Redshift occurs when the light waves from an object moving away from an observer are stretched, causing a shift towards longer wavelengths. This phenomenon is consistent with the Doppler effect, where the wavelength of light appears to stretch as the source moves away. The redshift of light from distant stars indicates that galaxies are moving away from us and from each other, supporting the idea that the universe is expanding.

2. Existence of cosmic background radiation: The discovery of cosmic background radiation further supports the theory of the expanding universe. Cosmic background radiation is a faint, uniform microwave radiation that permeates the entire universe. It is believed to be residual radiation from the Big Bang, the initial event that is thought to have initiated the expansion of the universe. The presence of cosmic background radiation provides strong evidence for the hot, dense early stages of the universe and its subsequent expansion.

Explanation:

No, plants do not take in air with their roots. Roots are designed to absorb water and minerals from the soil. In order to get the air and carbon dioxide they need for photosynthesis, plants have specialized structures called stomata in their leaves and stems that allow air to enter and exit. These stomata regulate the movement of gases into and out of the plant, so the plant can take in the carbon dioxide it needs and release the oxygen it produces.

Answer:fter photosynthesis, plants release oxygen into the atmosphere. This is one of the most significant ways that plants contribute to the carbon cycle's oxygen cycling.

In the process of photosynthesis, plants create oxygen and glucose, a form of sugar, from carbon dioxide, water, and sunshine. Animals and other species use the waste product of photosynthesis, oxygen, which is discharged into the atmosphere, for breathing. Overall, photosynthesis and plant respiration are just two examples of the numerous creatures and natural processes that contribute to the intricate process of oxygen cycling in the carbon cycle.
