To solve this, we must be knowing each and every concept related to speed, acceleration and its calculation. Therefore, the given statement is false.
What is speed?Speed may be defined as the distance traveled by an item in the amount of time it requires to travel that distance. In other words, it measures how rapidly an item travels but does not provide direction. The term "velocity" refers to the combination of direction and speed.
Acceleration is defined by the rate at which an object's velocity changes with respect to time. When an object's velocity changes, it is referred to as accelerating or to have acceleration. Speed does not include the direction of an object's motion. Acceleration include the direction of an object's motion.
Therefore, the given statement is false.

What is the glacial retreat?The glacial retreat is when the terminal does not extend as far.
When the ice melts quicker than the snow falls, the retreat of glacial occurs.
When the glacier loses its ice more it gains, than water level rises.
Sometimes, the pieces of ice rocks float in between the water.

Which statement correctly explains the weight you would experience on each
planet?
OA. You would weigh the same on both planets because your mass
would be the same on both.
OB. You would weigh more on planet A because it has less mass than
planet B.
OC. You would weigh the same on both planets because the planets
are the same size.
OD. You would weigh less on planet A because it has less mass than
planet B.
The statement that would correctly explains the weight you would experience on each planet is You would weigh less on planet A because it has less mass than planet B. Option D
How does mass affect weight?Weight is the force experienced by an object or person due to gravity. Since it is as a result of gravitational force, it depnds on both the mass of the objct or person and the level of gravity of the planet.
Gravity is dependent on th mass of the planet, and if planet A has lesser the mass of planet B, its gravitational force will be most likly be weaker.
This therefore means a person is going to weigh less on planet A than on planet B, even though both planets have the same size.

With respect to mammalian cell culture, which of the following statements is true? During the establishment of a cell line, senescence is the last stage of the cell's life. Rodent cells cultures undergo spontaneous transformation with similar frequency to human cell cultures. Media used for cell growth contain proteases and a divalent cation chelator to help cells adhere to the surface. Embryonic cell lines do not undergo senescence nor do they have a finite life span.
Answer:
Media used for cell growth contain proteases and a divalent cation chelator to help cells adhere to the surface.
Explanation:
Mammalian cell structure is the process where animals cells are grow in vitro in a flask or dish. The methods, equipments, reagents and supplies use in this type of culture prevent contamination and maintain cell culture purity. Protein enzymes like Serine protease breaks the cellular matrics interaction between the cells. In cell culture, the focal adhesions that are anchoring the cell to the culture dish is cut away. Most trypsin solutions for cell culture also contain EDTA which acts as a chelator for calcium. When calcium is remove from a solution, cadehrin that hold cells to each other break down and cells become separated from each other.

The three main components of a transport system are the Heart, Blood, and Blood vessels.
The function of the first main component, the heart, is to pump oxygenated blood throughout the body and receive the deoxygenated blood from the other various parts of the body. This impure blood is then sent to the lungs for oxygenation. The function of the blood is to transport the gases oxygen and carbon dioxide between the lungs and the rest of the body.
Blood also transports nutrients absorbed in the digestive system to all the other organs in the body. The function of the blood vessels is to act as the vessels required to transport blood throughout the body.

What happened to the “good” and antibiotic-resistant bacteria when they were exposed to the antibiotic (1-3 sentences)? What was the population's antibiotic resistance level like after antibiotic treatment (1 sentence)?
Answer: A diverse population of bacteria that is treated repeatedly with the same antibiotic and not all of them die will eventually lead to the emergence of antibiotic-resistant bacteria that will thrive and become dominant. The population's antibiotic resistance level before being exposed to the antibiotic was low or non-existent. The "good" bacteria will die while the antibiotic-resistant bacteria will survive and reproduce. After antibiotic treatment, the population's antibiotic resistance level will be higher than before.

12. Given the human pedigree to the right, is the trait indicated by
the darkened shapes a dominant or a recessive trait? How can
you tell?
Answer:
Darkened shapes are recessive
Explanation:
In the pedigree shown, we can see that 2 parents that are unshaded shapes have 2 children that are shaded shapes. This would be impossible if shaded shapes were dominant and unshaded shapes were recessive. This is because parents that have a recessive trait have 2 of the same alleles. So if 2 parents that both have a recessive trait have a child, the child will definitely have that trait. But we can see that this is not the case, the parents have 2 offspring that have different phenotype from the parents. This must mean the parents are heterozygous, meaning that they both have 2 alleles that are different. The dominant allele masks the recessive allele, so the dominant allele is expressed. In this case, the children inherited 2 recessive alleles, 1 from each parent, making them have a different phenotype from the parents.

1. Describe specific anatomical characteristics for typical cervical, thoracic, and lumbar vertebrae
2. Describe the structure of an osteon.
1.) Specific anatomical characteristics of typical cervical, thoracic, and lumbar vertebrae:
- Cervical vertebrae: There are seven cervical vertebrae in the human spine, located in the neck region. They are smaller and more delicate than the thoracic and lumbar vertebrae. Cervical vertebrae have a bifid (split) spinous process and transverse foramina, which allow passage of the vertebral arteries and veins that supply blood to the brain. They also have small, oval-shaped vertebral bodies and relatively large vertebral arches.
- Thoracic vertebrae: There are twelve thoracic vertebrae in the human spine, located in the upper back region. They are larger and more robust than the cervical vertebrae. Thoracic vertebrae have long, downward-pointing spinous processes and costal facets for articulation with the ribs. They also have heart-shaped vertebral bodies that are larger than those of the cervical vertebrae, but smaller than those of the lumbar vertebrae.
- Lumbar vertebrae: There are five lumbar vertebrae in the human spine, located in the lower back region. They are the largest and strongest of the vertebrae. Lumbar vertebrae have short, thick spinous processes and large, kidney-shaped vertebral bodies. They also have broad, flat transverse processes and no costal facets, as they do not articulate with the ribs.
2.) Structure of an osteon:
An osteon (also called a Haversian system) is a cylindrical unit of compact bone tissue that forms the basic structural and functional unit of bone. It consists of concentric layers of bone tissue called lamellae, which are arranged around a central canal called the Haversian canal. The Haversian canal contains blood vessels and nerves that supply nutrients and oxygen to the bone cells (osteocytes) and remove waste products. The osteocytes are located in small spaces called lacunae, which are connected by tiny channels called canaliculi. The canaliculi allow the osteocytes to exchange nutrients and waste products with each other and with the blood vessels in the Haversian canal. The osteons are interconnected by perforating canals called Volkmann's canals, which allow blood vessels and nerves to penetrate the bone tissue and connect adjacent osteons. Together, the osteons form a strong and flexible matrix that gives bone its characteristic strength and resilience.

2. Relative dating methods help scientists to
determine the age of the fossils within each layer
identify what rock types are present

assign a numerical date to each rock layer studied
Answer:
The correct answer is "identify the order in which rock units formed".
Explanation:
Relative dating methods are experimental approaches that allow to identify the relative order of past events. Instead of determining the absolute age of samples such as rocks or fossils, relative dating methods correlate which samples are older. Therefore, relative dating methods help scientists to identify the order in which rock units formed.
