The point at which the trachea (windpipe) divides into right and left primary bronchi may be determined by locating the sternal angle.

Answers

Answer 1
True.

The trachea is about 10 cm long and it has an approximate diameter of 2 cm. It is located anterior to (in front of) the esophagus and posterior to (behind) the isthmus of the thyroid. The right and left main bronchi are branches of the trachea. This division occurs at the level, or just below the level, of the sternal angle, also known as the manubriosternal joint.

Lipids are ___ molecules because they have no negative and positive poles

Answers

Lipids are nonpolar compounds that are insoluble in water due to their hydrophobic nature, providing various functions such as energy storage, insulation, and participation in cellular structures.

Lipids are a diverse group of compounds that are largely nonpolar in nature. They are hydrocarbons, consisting mainly of nonpolar carbon-carbon or carbon-hydrogen bonds. This nonpolar characteristic makes lipids hydrophobic ("water fearing"), meaning they are insoluble in water. Lipids serve various crucial functions in cells, ranging from energy storage in the form of fats to providing insulation for plants and animals. They also play an essential role in the formation of cellular membranes and are the building blocks of many hormones.

During the course of successful prenatal development, a human organism begins as a(n) _____ and ends up as a(n) _____.

Answers

The correct answers are zygote and fetus. This is correct because the initial joining of the sperm and the egg is called the zygote. The zygote is the first step in prenatal development that grows and transforms over months into the final form, a fetus. The fetus is the last form of the zygote prior to birth.
Final answer:

Throughout prenatal development, a human organism begins as a zygote and becomes a newborn. The fetus stage spans from the ninth week of gestation until birth, during which vital development and differentiation occur.

Explanation:

During the course of successful prenatal development, a human organism begins as a (n) fertilized egg (zygote) and ends up as a (n) newborn. Throughout prenatal development, specifically starting from the ninth week of gestation, the organism is referred to as a fetus. This is an important stage in human development that continues until birth, marked by immense cell growth and the differentiation necessary to fully develop the structures and functions of the immature organ systems that were formed during the embryonic stage.

The entire prenatal journey encompasses several stages, starting with the germinal stage immediately after fertilization, proceeding through to the embryonic stage which lasts until the eighth week, and finally entering the fetal stage from the ninth week to birth. Significant development occurs during these stages, including sexual differentiation within the fetal period, organogenesis, and other crucial processes. The result of this intricate process is the birth of a human capable of survival outside the womb.

Transmission electron microscope - The transmission electron microscope uses electrons instead of light. a light microscope is limited by the wavelength of light. TEMs use electrons as "light source" and their much lower wavelength makes it possible to get a resolution a thousand times better than with a light microscope. The possibility for high magnifications has made the TEM a valuable tool in both medical, biological and materials research.Compound light microscope - Microscope with more than one lens and its own light source. There are ocular lenses in the bonicular eyepieces and objective lenses in a rotating nosepiece closer to the specimen. To ascertain the power of magnification of a compund light microscope, it's needed to take the power of the objective lens and multiply it by the eyepiece which is generally 10x. Although sometimes found as monocular with one ocular lens, the compound binocular microscope is more commonly used today. The first light microscope dates back to 1595, when Zacharias Jansen created a compound microscope that used collapsing tubes and produced magnifications up to 9X.

Which would feel warmer to the touch a bucket of water at 50 or a bathtub filled with water at 25?

Answers

A bucket of water at 50 degree of bathtub will feel warmer to the touch than a bathtub filled with water at 25. This is because, the water at 50 degree has more temperature compare to the one at 25 degree. The water at 50 degree has higher temperature because its molecules possess more kinetic energy and are moving at faster rate.

In a test cross, peas of an unknown genotype are crossed with peas of a known genotype. in this example, smooth peas are the unknown and wrinkled peas are the known (rr). if half of the offspring from that cross are smooth and half are wrinkled, what is the genotype of the unknown plant?

Answers

Final answer:

The unknown genotype for smooth peas that produces half smooth and half wrinkled offspring when crossed with wrinkled (rr) peas must be heterozygous (Rr). If the parent plant is heterozygous, the probability of getting three round pea offspring in a single sample is 27/64.

Explanation:

In genetics, a test cross is used to determine the genotype of an individual expressing a dominant trait when crossed with an individual expressing a known recessive trait. In this case, smooth peas have a dominant phenotype and wrinkled peas have a recessive phenotype (rr).

Considering the scenario where the unknown genotype for round peas produces offspring that are half smooth and half wrinkled when crossed with rr peas, it suggests that the unknown plant is heterozygous (Rr). This is because a homozygous dominant plant (RR) would not produce any wrinkled progeny when crossed with a rr plant, as R is dominant over r and all offspring would display the dominant round phenotype. On the other hand, a heterozygous plant (Rr) crossed with a homozygous recessive plant (rr) would produce offspring with a 1:1 ratio of round to wrinkled peas, explaining the observed results.

If the round pea parent plant is heterozygous (Rr), the probability that a random sample of three progeny peas would all be round can be calculated. Since the round pea (R) is dominant over the wrinkled pea (r), each offspring has a 3/4 chance of being round. Therefore, the probability of all three being round is (3/4) × (3/4) × (3/4) = 27/64.

Why is it important to constantly swirl the contents of the beaker after the catalase has been added to the hydrogen peroxide?

Answers

Catalase is an enzyme which breaks down hydrogen peroxide into water and oxygen. Hydrogen peroxide is a toxic by-product of metabolism, so it is essential for it to be broken down quickly, or else,  it would cause damage to cells. Without the aid of catalase, decomposition would take much longer, thus, would not be fast enough to sustain human life. Some experiments are done to determine the rate of an enzymatic reaction between catalase and peroxides. In decomposition reaction of peroxide by catalase , the easiest molecule to measure would be oxygen as a final product. While certain procedures are applied in determining the amount of oxygen, the techniques of swirling are applied for accuracy of reactions. Swirling is important because it makes it possible for further collisions to take place between the catalase enzyme and the hydrogen peroxide. More collisions mean the reaction is occurring to the fullest achievable extent.

The limiting factor of a desert biome is its _____.

Answers

if you are in a desert the limiting factor would be water

Answer: The limiting factor of a desert biome is its 10 cm of annual rainfall.

A desert is a biome which receives less than 10 inches of rainfall per annum and has no or sparse vegetation.

In ecological terms, the limiting factor refers to any natural resource or condition which limits the population size. The rainfall received by a desert biome is very less and the water received as precipitation either gets evaporated or gets frozen in hot and cold deserts respectively. Very few plant and animal species can adapt to such harsh conditions for their survival.

Therefore, water becomes a limiting factor of a desert biome apart from the extreme temperatures and food scarcity.
