The first amphibians evolved about 400,000 years ago.
True or False?
Answer:
False
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.

Suppose a scientist identifies a rocky planet with a thin atmosphere in a different solar system. Based on the characteristics of planets in our solar system, what might the scientist predict?
A. Like Neptune, the planet has a layer of methane gas
. B. The planet is likely to have
many moons
.
C. The planet is close to its sun the way Mercury is close to the sun in our solar system
D. A year on the planet is likely to be many times longer than a year on Earth.
Answer: The correct option is C.
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.
Analogous structures often develop through the process of _____ evolution, rather than a close evolutionary relationship.
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.

Is the definition of synthetic? Is it not real or a copy
Answer:
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.
What part of the cell is selectively permeable and critical for maintaining homeostasis?
Answer:
The cell membrane
Explanation:
One way that a cell maintains homeostasis is by controlling the movement of substances across the cell membrane. The lipid bilayer is selectively permeable to small, nonpolar substances. Proteins in the cell membrane include cell-surface markers, receptor proteins, enzymes, and transport proteins.
What happens when rainwater hits sand?
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.

Explain how electron microscopes work and why some scientists might prefer to use electron microscopes instead of light microscopes.
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.

Give an example of an organ that is included in more than one organ system. How does the organ's functions offer a unique contribution to each system?
Answer:
The correct answer is - ovaries.
Explanation:
Ovaries are organ which plays a distinct role in two different organ system and both roles of the organ are essential. Ovaries not only produces egg in the reproductive system but also produces the hormone which is part of the endocrine system.
The endocrine system is a system of chemical messengers which depends on the feedback loop to release the chemical messenger or hormone directly to the circulatory system, ovaries are part of this system as it produces a hormone.
Which of the following characteristics suggests that whales evolved from terrestrial animals?
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).
Distinguish between the fossils of ice age mammals found in the La Brea Tar Pits and the organisms that make up the
fossil fuels of the tar.
Answer:
Explanation:
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.

In an ECG pattern, the P wave is caused by?
Answer:
Depolarization of atrial muscle fibers
The P wave in an electrocardiogram (ECG) pattern is caused by the depolarization (contraction) of the atria.
What does this represent?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.

Compare and contrast what happens in mitosis and meiosis.
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:
Both types of cell division take place in the nuclei of the cell.Both involve some common stages like prophase, metaphase, anaphase, and telophase. Both forms of cell division initiate from a diploid parental cell. The occurrence of DNA synthesis happens in both sorts of cell divisions.What is Meiosis?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:
Mitosis produces two daughter cells of diploid nature from a parental cell. These daughter cells are genetically identical to their parental cells. Meiosis produces four daughter cells of haploid nature from a parental cell. These daughter cells are genetically different from their parental cell.Therefore, it is well described above.
