Explanation:
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.

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.

a liquid that exits the scrotum once meet with high friction and or sexual action that has properties to create a live egg capable of birth
Answer:
semen/seminal fluid
Explanation:
The "semen" consists of sperm cells and other secretions. These secretions come from the seminal vesicles, prostate gland, testicles, epididymis, bulbourethral and urethral glands.
Once the male is aroused (through sexual action), the penis gets larger and this causes the release of the semen from the scrotum (regulates the temperature of the testes). Such process is known as "ejaculation." This fluid has a high potential to make a woman give birth.
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.

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.
How does a cell maintain homeostasis?
A. Regulates what enters and leaves the cell
B. Structure and support
C. Flexibility
D. Protective barrier
Answer:
A
Explanation:
In order to maintain balance within the cell, it has a plasma membrane that is able to regulate what substances enter and leave the cell.

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.
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).
which of the following best describes C-K Theory
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.
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.
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.
