They are constantly filtered by the nose, which prevents lung absorption
Answer:
B
Explanation:
The role the ultrafine particles play in dirty air is that they can worsen symptoms for people with breathing difficulties. The correct answer is b).
What are ultrafine particles?The term "ultrafine particles" (UFPs) refers to particles with a dimension of less than micrometers and more than 0.1 micrometres (100 nanometers), also known as nanoscale particles. The majority of the ultrafine particles are found on motorways and are mostly produced by vehicle emissions.
It has been demonstrated that ultrafine pollution particles may play a crucial role in igniting extra pathways or inflammation, which worsens asthma disease. The ultrafine particles released by motor vehicles and other sources of combustion are covered with an organic chemical coating that can be inhaled.
By oxidizing cells and tissues, these substances create free oxygen radicals that activate the immune system in the lung. For those who have asthma, oxidation exacerbates the allergic inflammation in their lungs.
Therefore the correct option is b).

One conclusion drawn from the experiment was that life span differences were independent of reproductive investment. If that is the case, then which of the following statements is true? Females that exhibited catch-up growth and produced many eggs had longer life spans than females that exhibited catch-up growth and produced few eggs. Females that exhibited catch-up growth and produced few eggs had longer life spans than females that exhibited catch-up growth and produced many eggs. Females that exhibited slowed growth and produced many eggs had longer life spans than females that exhibited slowed growth and produced few eggs. Females that exhibited slowed growth and produced few eggs had longer life spans than females that exhibited slowed growth and produced many eggs. Females that exhibited slowed growth and produced few eggs had similar life spans to females that exhibited slowed growth and produced many eggs.
Answer:
The correct answer is - Females that exhibited slowed growth and produced few eggs had similar life spans to females that exhibited slowed growth and produced many eggs.
Explanation:
According to the question, the life span differences were independent of reproductive investment, on the basis of this experiment, it is clear that the sexual gametes or egg which is a reproductive investment are independent of the lifespan of a female.
The life span of females could be slow growing or not but it will not affect the production of the gametes or eggs. Eggs production is dependent upon hormones produced.

Select an organism of your interest! Research to see if that organism undergoes asexual or sexual reproduction. Describe why that type of reproduction is advantageous for your organism.
Answer:
Many fungi and plants reproduce asexually. Some plants have specialized structures for reproduction via fragmentation.
Explanation:
This allows them to adjust to conditions in the environment. They can spread quickly through asexual reproduction when conditions are stable. They can increase their genetic variation through sexual reproduction when conditions are changing and variation may help them survive.
Reproduction is a method by which the genetic material from the parent is transferred to offspring and in this way the character and traits are passed from generations.
I will select plants for my research purpose.
Plants are species that reproduce sexually. They have male and female organs that produce cells for reproductions. They sexually reproduce through the process of pollination.
This method of reproduction helps in genetic variation and in forming recombinant species that are more variant.
This variation helps the plant species to survive better compared to less competent species.
Sexual reproduction is beneficial for plants as it increases varieties and helps plants in fighting against a common population disease.

n 2000, Bob Harmon discovered the best-preserved Tyrannosaurus rex skeleton ever found. The fossilized dinosaur was sticking out of the wall of a canyon in Montana. Many scientists were eager to study the fossils.
Dr. Mary Schweitzer got one of the leg bones to analyze. Dr. Schweitzer’s assistant dissolved the bones in acid and discovered that some soft tissue had survived even after 68 million years. The discovery was a shock to the scientific community. No one had ever found such old tissues.
Before laying eggs, female birds store calcium inside their bones that they will need to make eggshells. This layer of bone is called medullary bone. In the T. rex leg bone, Dr. Schweitzer found tissue just like the medullary bone of birds. The dinosaur was a female! If Dr. Schweitzer’s hypothesis is right, she is the first scientist to identify the sex of a T. rex. Which organ system includes the bones?
A. skeletal system
B. muscular system

According to this question, some students looked at pond water with a microscope and saw both prokaryotic and eukaryotic organisms. The organism displayed in the attached image is EUKARYOTIC simply because it has a NUCLEUS.
how proteins are made
Proteins are an important class of molecules that carry out most of the work inside cells. The building blocks of proteins are smaller organic molecules called amino acids. Most organisms, including humans, use only 20 different amino acids to assemble the vast multitude of proteins needed to build and run a cell.
To build proteins, cells use a complex assembly of molecules called a ribosome. The ribosome assembles amino acids into the proper order and links them together via peptide bonds. This process, known as translation, creates a long string of amino acids called a polypeptide chain.
After the polypeptide chain is synthesized, it will sometimes undergo additional processing. For example, some proteins will have certain amino acids removed. Or extra molecules such as sugars or phosphates may be attached to some of the amino acids in a protein.
Answer:
proteins are made of large numbers of amino acids joined end to end. The chains fold up to form 3d molecules with complex shapes - you could think of it as origami with very long and thin piece of paper

Answer: hello your question is in complete below is the complete question
A fiber reinforced composite contains e-glass fibers in an epoxy matrix. E for the glass is 72 GPA, E for the epoxy is 2.4 GPa. Find the elastic modulus of a composite that contains 5% fibers in the longitudinal direction, Ecl = ViEi + EmVm? (note Vi + Vm= 1.) O 5.88 GPa O 5.66 GPa O 2.52 GPa O 6.74 GPa
answer : 5.88 GPa
Explanation:
Fiber reinforced composite containing e-glass fibers
E for the glass ( Ei ) = 72 GPa
E for the epoxy ( Em ) = 2.4 GPa
Determine the Elastic modulus of a composite containing 5% fibers
percentage of glass = 5% = Vi = 0.05
∴ percentage of epoxy = 95% ; Vm = 0.95
using the relation included in the question
Ecl = Ei Vi + Em Vm
= ( 72 * 0.05 ) + ( 2.4 * 0.95 )
= 3.6 + 2.28 = 5.88 GPa

with 75% of their mass being hydrogen and 25% helium.
Celestial objects that are formed mostly of the elements hydrogen and helium are gas giants and dwarf planets. Gas giants are large planets, such as Jupiter and Saturn, which are composed primarily of hydrogen and helium.
What is the reason of calling them Jovian planets ?These planets are also known as Jovian planets, and they are much larger than the terrestrial planets, such as Earth, that are made up of rock and metal. Gas giants have no solid surface and are composed mostly of gas and liquid.
Dwarf planets are smaller than gas giants and are made up of a combination of rock and ice. These objects are too small to be considered full-fledged planets, but they still have characteristics of planets such as an atmosphere, moons, and an orbit around the sun.
Although these objects are composed of different materials than gas giants, they still contain significant amounts of hydrogen and helium. In contrast, rocky planets and asteroids are composed of materials such as rock, metal, and ice. Rocky planets, such as Earth, are composed mostly of iron, silicon, magnesium, and other elements
Hence, . Asteroids are small, rocky objects that are found in the asteroid belt between Mars and Jupiter. These objects are composed of rock, metal, and ice, and contain very little hydrogen and helium.
