The geological time scale/species scale is divided into different units of time depending on changes in the rocks and fossils. So the statement is true.
What is the geological time scale?
The lengthy period of time that the Earth's geologic history has taken up is known as geologic time. Starting at the beginning of the Archean Eon (4.0 to 2.5 billion years ago), formal geologic time runs to the present.
The Hadean Eon, an informal time period that runs from around 4.6 billion years ago (corresponding to Earth's first creation) to 4.0 billion years ago, is also frequently included in modern geologic time scales. The period of Earth's history that is reflected by and preserved in the planet's rock layers is known as geologic time.
Events throughout Earth's history are "calendared" according to the geologic time scale. It divides all of the time into named units of abstract time known as eons, eras, periods, epochs, and ages, in declining order of duration. Those geologic time units are counted according to stratigraphy, the correlation, and the categorization of rock layers.
Therefore, the geological time scale is used for dividing different units of time according to changes in rocks and fossils. Hence the statement is true.

Match the following enzymes involved in DNA replication with their functions.
a. DNA ligase
b. DNA polymerase
c. DNA gyrase
d. helicase
Answer:
DNA ligase is an enzyme which can connect two strands of DNA together by forming a bond between the phosphate group of one strand and the deoxyribose group on another.
DNA polymerase is an enzyme that synthesizes DNA molecules from deoxyribonucleotides, which are the building blocks of DNA. The enzymes play an essential role in DNA replication, usually working in pairs to produce two matching DNA stranges from a single DNA molecule.
DNA gyrase is an essential bacterial enzyme that catalyzes the ATP-dependent negative super-coiling of double-stranded closed-circular DNA
Helicases are enzymes that bind and may even remodel nucleic acid or nucleic acid protein complexes. There are DNA and RNA helicases. DNA helicases are essential during DNA replication because they separate double-stranded DNA into single strands allowing each strand to be copied.
Explanation:
DNA ligase seals the fragment, DNA polymerase adds a new nucleotide, DNA gyrase unwinds the DNA, and helicase makes a dent in double helix.
What is DNA replication?DNA replication is the physiological method that generates two identical replicas of DNA from a single original DNA molecule in molecular biology.
DNA replication takes place in all living organisms and is the most important component of biological inheritance.
Helicase, primase, DNA polymerase, and ligase are the four main enzymes that aid in DNA replication.
Many proteins and enzymes play a role in DNA replication, including: Topoisomerase: This enzyme relaxes the super-coiled nature of DNA. Helicase: Helicase is a protein that separates the two strands of DNA at the replication fork.
The fragment is sealed by DNA ligase, a new nucleotide is added by DNA polymerase, the DNA is unwound by DNA gyrase, and a dent in the double helix is made by helicase.
Thus, this can be the match for the given scenario.

Examples of ovoviviparous animal
Answer:
sharks, rays, snakes, fishes, and insects
Explanation:
These ovoviviparous animals produce eggs, but instead of laying eggs, eggs develop inside the mother's body. The eggs are laid in the mother. After rocking, they stay in the mother for a while and feed there. Then the young are born live.
Ovoviparity is, therefore, a mixture of oviparous (animals that lay eggs) and viviparous (animals that develop in the mother’s body).

The population size was constant for a period of time, increased rapidly, and then became constant again. an unlimited food supply a natural disaster a population crash a reduction in predators
Answer:
A reduction in predators
Explanation:
I just took the test
A reduction in predators could explain the curve in this population growth graph.
How does reduction in number of predators lead to curve?The prey species soon degrades and overruns its area since there are no predators to regulate the population and modify feeding behavior.When food becomes scarce, people grow unwell and famished, and they either flee or crash.When predator populations grow, putting more pressure on prey populations and acting as a top-down control, pushing them toward extinction. As a result, the size of prey populations is influenced by both resource availability and predation.

The IQ range that indicates moderate mental *********** is A. 70-79.
What is an IQ?
IQ stands for Intelligence Quotient and is a measure of cognitive abilities and intellectual potential. It is determined through standardized tests that assess various cognitive skills, including problem-solving, memory, and analytical thinking.
The average IQ score is set at 100, with scores ranging from 70 to 130 considered to be within the normal range. Scores below 70 indicate varying degrees of intellectual disability, while scores above 130 suggest above-average intelligence.
While IQ scores can provide insight into a person's cognitive abilities, they do not account for other factors, such as emotional intelligence or creativity, that may contribute to overall success in life. It is essential to recognize that IQ tests have limitations and should not be used to label individuals or limit their potential.
This range is considered to be a mild to moderate intellectual disability, indicating limitations in adaptive functioning and potential need for support in daily life activities.

Describe your diagnosis for the patient. How did the chlorine gas affect concentration difference, diffusion distance, and surface area in the patient’s lungs? Explain how these affected the diffusion rate.
The concentration difference and surface area lead to decrease but the diffusion distance increases due to application of chlorine.
The difference in the concentration of a substance between two regions is known as the concentration gradient.
Surface area is the total area that the surface of the object occupies.
Diffusion rate is defined as the change in the quantity of diffusing molecules inside the cell in a specific period of time.
The chlorine gas greatly affected the concentration difference because it lowers the value. The gas increases the diffusion distance but decreases the surface area of the patient's lungs. The decrease in the concentration difference leads to slower the diffusion rate.
It is because there is less difference in the concentration of both regions i.e. lungs and the surrounding atmosphere and when there is equal amount on both sides the diffusion of gas molecules stopped so we can say that decrease occur in the concentration difference and surface area but increase occur in the diffusion distance

Over various spans of time, human populations have increased, decreased, or remained the same, and at both global and local levels. Which statement best explains this observation?
Answer:
C. Like other populations, the human population is affected by a variety of factors in the environment
Note: The options are found in the attachment below
Explanation:
Factors that affect population in the natural world include; availability of food, water, shelter, space, competition for resources, predation, as well as disease.
These factors also affect human population resulting in an increase, decrease or stability in population.
Regarding decrease in population, factors like competition for scarce resources has resulted in wars which greatly reduced human population. Also disease outbreaks, droughts, famines, etc have resulted in decrease in population.
Availability of food, water, shelter and space on the other hand makes for an increase in population by increasing the birth rate, reducing competition and bringing stability.
In some other instances, overtime, there is a balance between birth and death rate, so human population will remain relatively unchanged at these times.

B. Space in the lungs increases
C. Lung pressure decreases
D. Air moves from low pressure (in the lungs) to high pressure (outside)
Answer:
Conversely, exhalation moves the diaphragm up into the chest cavity and reduces the space in it. This forces the air, which is dense with carbon dioxide at that point, out of the lungs and windpipe. It then exits the body either through the nose or mouth. Usually, this requires no physical effort from the body.
