In healthy individuals, friction is a major factor affecting pulmonary ventilation

Answers

Answer: Infant Respiratory Distress Syndrome occurs when there is a lack of surfactant  produced. This is common in premature infants.

Explanation:

Respiratory distress syndrome (RDS) is a well-known breathing disorder that is common in premature infants. It happens when there is a lack of surfactant produced in the baby's lungs which is quite bad because surfactant enables babies to breathe when they are born by keeping the lungs expanded.

It is common in premature infants because the lungs only begin to produce surfactant in the third trimester so babies that are born prematurely did not get to produce sufficient quantities. If not treated immediately, brain damage could follow.

Blood type analysis is used frequently as evidence in paternity suits. Consider the following
hypothetical cases presented in the table. The blood type of the mother and child are given; indicate which
blood type(s) MUST be the father's for each situation.

Answers

Answer:

Row 1: Any blood type except AB

Row 2: Blood type A/AB

Row 3: Any blood type except AB

Row 4: Any blood type

Row 5: AB/B

Explanation:

1. If the blood type was AB for the first one (two dominant alleles) then O could not appear as it is recessive.

2. The blood type must contain at least one A allele as AB is obtained from I^A and I^B (already provided by the mother).

3. Once again, the blood type must carry at least one recessive O allele for the O blood type to occur in this child.

4. As long as the blood type either carries a recessive O or another B, the blood type will result in a B.

5. The blood type of the father must contain at least one B for the child to have a B blood type.

Fibroblasts can be placed on thin sheets of silicone rubber. Under normal circumstances, fibroblasts exert sufficient tension on the rubber so that it visibly wrinkles. Explain how the ability of fibroblasts to wrinkle rubber would change if the cells were treated with a permeable form of C3 transferase, a toxin (from the bacterium Clostridium botulinum) that covalently modifies an amino acid in Rho. The modification renders Rho unable to bind to proteins that it would normally bind to when active.

Answers

Answer:

C3 transferase decreases Rho activity and contractility by decreasing the number of stress fibers and thus also reducing wrinkles

Explanation:

Rho protein is a small GTPase, i.e., an enzyme that binds GTP to hydrolyze it to GDP, which is known to mediate the formation of stress fibers and focal adhesion. Rho protein is involved in diverse cellular functions including, among others, adhesion, motility, and division by reorganization of the actin cytoskeleton. The bacterial toxin C3 transferase derived from Clostridium botulinum is able to lock Rho in an inactive state. C3 transferase adds an ADP-ribose to Rho, thereby leading to the accumulation of a Rho-guanine nucleotide dissociation inhibitor (GDI) complex in the cytoplasm. In consequence, C3 transferase functions to decrease contractility by blocking Rho activity, decreasing the number of stress fibers and leading to a reduction in wrinkles.

How do divisions in the geologic time scale differ from the way we organize time using a clock?

Answers

Explanation:

The Earth's geologic past is divided into hierarchical time periods. This hierarchy comprises eons, eras, times, epochs, and ages, from largest to smallest. The Cenozoic, Mesozoic, and Paleozoic Periods are the three main divisions of the Phanerozoic.

The geological timescale is the official earth clock and differs from the way we organize time using a clock, as the planet's time is too long for us to use measures of hours.

Geologic timescale

Planet Earth is about 4.5 billion years old. To better understand its history, scientists divide geologic time into five levels of classification, called chronostratigraphic units:

EonsErasPeriodsEpochsand ages.

Eons are large and indeterminate spans of time and are divided into four classifications:

Phanerozoic (last 542 million years)ProterozoicArcheanand Hadean.

Of them, only the Hadean is not divided into ages. The ages are characterized according to the different positions of continents, oceans and their living beings. Within the ages are divided in the periods. Epochs, in turn, are divisions within periods and are divided into ages. According to the researchers, we currently live in the Quaternary period of the Cenozoic era.

To get a rough idea of ​​how much the existence of the human being is a mere recent episode in Earth's geological time, we use some analogies. For example, if the entire history of the planet were summarized in the twenty-four hours of a day, the existence of humanity would have occurred in the last three seconds of that same day.

Understanding the dimension of geological time and its scales of measurement becomes a fascinating mental exercise to better understand the role of man in relation to this temporality and his role as heir of all the transformations that have taken place in terrestrial space throughout the geological ages.

Lower the amount of sea ice in polar areas. This will warm the water,

Increase the temperature difference between the upper and lower parts of

Winds blowing in opposite directions form a cylinder that might get tipped up by a supercell’s ________.

Plz Help!!! God Bless You

Answers

B eye like the eye of a hurricane storm but the answer is not a or d or c

Winds blowing in opposite directions form a cylinder that might get tipped up by a supercell’s updraft.

What do you mean by updraft?

Updrafts are found when a wind blowing at a hill or mountain has to rise to climb over the hill. Updrafts can also be caused by the sun heating the ground. The heat from the ground warms the surrounding air, which causes the air to rise. The rising pockets of hot air are called thermals.

The definition of an updraft is a strong upward current of air. When a big gust wind comes along and catches on the umbrella on your outside table from underneath, knocking your umbrella and table over with its power, this big gust of wind is an example of an updraft.

When warm, moist air moves upward in an updraft, puffy cumulus clouds may form in the atmosphere. The moisture in the air condenses into water droplets as it rises. The cloud will continue to grow as long as warm air from below continues to rise.

Answer:

Explanation:

An abiotic factor is a part of an ecosytem, but it is not alive. Some examples include water, rocks, sunlight, and the atmosphere.

On the other hand, a biotic factor is a living part of an ecosystem. Some examples are animals, plants, and fungi.

Let's look at the answer choices.

A creosote plant (choice A) kangaroo rat (choice C) and coyote (choice D) are all living organisms. Therefore, they must be biotic factors.

However, rocky desert soil (choice B) is not living. It's a part of the ecosystem, but since it's not alive it must be abiotic.

Answers

Wind because you can always get it make with photosynthesis

Wind is the natural resource which is renewable. Therefore, option (B) is correct.

Wind energy is considered a renewable resource because it comes from the natural flow of air masses caused by the sun and the Earth's rotation. Wind turbines turn the kinetic energy of the wind into power, and as long as there is wind, this process can keep going forever.

Wind doesn't run out like coal and oil (options A and D), which are both solid fuels. Topsoil (choice C) is an important resource for agriculture, but it can be worn down or eroded over time, making it non-renewable in the short run if it is not managed well.

Examples of physical properties include density, index of refraction, magnetization and chemical composition. A simple description is that a phase is a region of material that is chemically uniform, physically distinct, and (often) mechanically separable. In a system consisting of ice and water in a glass jar, the ice cubes are one phase, the water is a second phase, and the humid air is a third phase over the ice and water. The glass of the jar is another separate phase. (See state of matter § Glass)
