Explanation:

Synthetic is something that is not made from natural materials but rather made from the synthesis of other materials in a lab. This is mostly done in clothing where you have some natural materials like cotton and other materials that are synthetic. This doesn't mean it is not high quality. It is actually preferable for some sports for example to wear synthetic clothing instead of cotton.

Answer:

Electron microscopes differ from light microscopes in that they produce an image of a specimen by using a beam of electrons rather than a beam of light. Electrons have much a shorter wavelength than visible light, and this allows electron microscopes to produce higher-resolution images than standard light microscopes.

Answer:

B procaryotes

Explanation:

I just got it right

Bacteria are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large domain of prokaryotic microorganisms. Therefore, option (B) is correct.

Bacteria are minute, single-celled creatures found in millions.

Bacteria come in a wide variety of varieties. One approach to categorize them is according to form. The fundamental forms are three.

Every form group contains a wide range of variants.

Therefore, option(B) is the correct answer.

Answer:

The correct answer is - convergent evolution.

Explanation:

The convergent type of evolution involves the process in which non-related organisms evolved independently and still develop similar kinds of traits or structures due to factors such as ecological or environmental conditions. This environmental condition could be an ecological niche or issues faced by the organisms which force them to adapt accordingly.

For example, dolphins and shark look similar but are different organisms. Analogous organs or structures arise due to the convergent evolution as they have different ancestry still shows structures similar to one another.

Answer:

When we mix sand and water, no reaction takes place. The sand simply settles down at the bottom of the water container. This is because sand is heavier than water and hence cannot float in water. The sand can be separated from the water by simple filtration and can be obtained in its original condition after drying.

Answer:

The traditional hypothesis of cetacean evolution, first proposed by Van Valen in 1966, was that whales were related to the mesonychids, an extinct order of carnivorous ungulates (hoofed animals) that resembled wolves with hooves and were a sister group of the artiodactyls (even-toed ungulates).

Explanation:

Amphibians evolved about 365 million years ago from a lobe-finned fish ancestor. As the earliest land vertebrates, amphibians were highly successful for more than 100 million years until reptiles took over as the dominant land vertebrates. The earliest well-known amphibian, Ichthyostega, was found in Late Devonian deposits in Greenland, dating back about 363 million years. The earliest amphibian discovered to date is Elginerpeton, found in Late Devonian rocks of Scotland dating to approximately 368 million years ago.

Answer:

Depolarization of atrial muscle fibers

The P wave in an electrocardiogram (ECG) pattern is caused by the depolarization (contraction) of the atria.

It represents the electrical activity that initiates the contraction of the atrial muscles, which is responsible for pumping blood into the ventricles.

The depolarization wave starts at the sinoatrial (SA) node, also known as the natural pacemaker of the heart, and spreads throughout the atria, leading to their contraction.

The P wave is the first deflection seen on an ECG and signifies the initiation of the cardiac electrical cycle. It provides valuable information about the atrial function and can help diagnose certain cardiac conditions.

Mitosis and Meiosis-their differences and similarities

Similarities: both mitosis and meiosis are multistage processes. The stages are interphase, prophase, metaphase, anaphase and telophase. The same general processes occur in each of these stages for mitosis and meiosis. Interphase is cell growth and DNA replication in preparation for cell division

Differences:(please find it attached below)

The similarities between mitosis and meiosis are as follows:

Meiosis may be defined as the type of cell division that occurs in the germs cells of an individual. In this type of cell division, one parental cell produces four haploid daughter cells. It is also known as reductional division.

The differences between mitosis and meiosis are as follows:

Answer:

C-K theory describes and explains the reasoning of a designer as he thinks of and designs a new object – a new product, service, or process. In addition to its explanatory power, this theoretical framework provides powerful generative mechanisms to overcome cognitive obstacles, thus improving our ability to innovate.

Explanation:

C-K design theory or concept-knowledge theory is both a design theory and a theory of reasoning in design. It defines design reasoning as a logic of expansion processes, i.e. a logic that organizes the generation of unknown objects.

The planet is close to its sun the way Mercury is close to the sun in our solar system.

Explanation:

Solar system consists of the Sun and the eight planets, dozens of moons, asteroids,comets, meteoroids. The names of the eight planets includes:

-- Mercury

-- Venus

-- Earth

-- Mars

-- Jupiter

-- Saturn

-- Uranus and

-- Neptune.

Mercury is a rocky planet with a thin atmosphere. It is the smallest terrestrial planet and the closest to the sun. It is said to have a thin atmosphere because it lacks hydrogen. The atmosphere gets thinner as one moves further away from the planets surface.

Mercury is a rocky dense planet because its composed mainly of iron and nickel with an iron core. It is also covered by a thin layer of tiny particle silicates.

Therefore the rocky planet with a thin atmosphere identified by the scientist must be a planet that is close to its sun the way Mercury is close to the sun in our solar system.

The tar located in the La Brea tar pits is today a fossil fuel that began its formation many hundreds of millions of years ago from the bodies of marine organisms. During the last ice age that ended a few tens of thousands of years ago, some animals got trapped in the tar and left their bones behind. They are not something that created it but only got trapped in preexisting tar.

Answer:

The tar in the La Brea Tar Pits is a fossil fuel that began forming hundreds of million years ago from the bodies of marine organisms. During the last ice age, a few tens of thousands of years ago, mammals like mammoths and sabertooth cats, became trapped in the tar, leaving their bones behind. The mammals became trapped in the tar that already existed, and were not in fact part of what created it.
