When multiple transitional fossils are found in many rock layers, they provide evidence of —
A) seasonal variation in the diet of a species
B) gradual change of a species over time
C) DNA functioning as the genetic material of organisms
D) an unchanging environment
Answer:
your Answer is B:)
Explanation:
When multiple transitional fossils are found in many rock layers, they provide evidence of the gradual change of a species over time.
What do you mean by Fossils?Fossils may be defined as the preserved remains, or traces of remains, of ancient organisms. They are dead and organic remains of past organisms.
Transitional fossils are fossils that exhibit characteristics of both ancestral and derived forms During the past 30 years, new discoveries and reinvestigations of long-forgotten specimens have coalesced into a flood of transitional fossils.
Therefore, when multiple transitional fossils are found in many rock layers, they provide evidence of the gradual change of a species over time.

A river has historically had a large population of wetland grasses growing near the shore. Which statement describes the most likely long-term effect of introducing an aggressive, nonnative aquatic plant species into the river?.
Answer:
The grasses will adapt to live on dryer soil.
Explanation:
The statement describes the most likely long-term effect of introducing an aggressive, nonnative aquatic plant species into the river is the grasses will adapt to live on dryer soil.
What is nonnative species?The nonnative species also known as non-indigenous species. The any species which is not found in ecosystem is called nonnative species. The species introduced naturally and not by human agency.The non-native species that causes harm to the environment or ecosystem is called invasive species.
The most likely effect these nonnative flathead catfish could have on the ecology of the Yadkin river is that they could cause a decline in the population of native fish species that they prey on.
Nonnative refers to any species that is not native to a particular area or ecosystem. Nonnative species can be referred to as exotic, alien, or introduced species.

12. A farmer is struggling to control the population of a certain insect on his farm. After researching population control techniques, he discovers that a particular bird is a predator of this insect. The farmer purchases a number of these birds and releases them onto his farm. How might the farmer's action most likely have a negative impact on the ecosystem
The farmer's action most likely have a negative impact on the ecosystem because may be there is no predator or controlling agent of that bird.
Why introduction of new bird cause problem?We know that one organism is responsible for controlling the population of other organism so if such type of controlling agent is present, the organism grow rapidly and can harm the whole ecosystem.
So we can conclude that farmer's action have a negative impact on the ecosystem due to presence of no predator or controlling agent of that bird.

How do stem cells relate to the cell cycle?
Answer:
Murine, primate and human embryonic stem cells (ESCs) exhibit a very unusual cell cycle structure, characterized by a short G1 phase and a high proportion of cells in the S-phase.
Explanation:
Normally, embryonic stem (ES) cells proliferate quickly during differentiation and do not differentiate simply by cell cycle slowing. In this paper, it is shown that the role of the cell cycle in terminal stages of differentiation can be adapted for and extended into ES cells.

7)Explain how Muslims can understand DNA from the Islamic Worldview
Answer:
DNA
DNADNADeoxyribonucleic acid is a polymer composed of two polynucleotide chains that coil around each other to form a double helix carrying genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses. DNA and ribonucleic acid are nucleic acids.
2) (i) A pentose sugar is a monosaccharide with 5 carbon atoms. Pentose sugars are the deoxyribose sugars, which are part of nucleotides in DNA
(Ii) a phosphate is an anion, salt, functional group or ester derived from a phosphoric acid. It most commonly means orthophosphate, a derivative of orthophosphoric acid H ₃PO ₄. The phosphate or orthophosphate ion [PO ₄]³⁻ is derived from phosphoric acid by the removal of three protons H⁺
Formula: PO₄³⁻

(III) Nucleobases, also known as nitrogenous bases or often simply bases, are nitrogen-containing biological compounds that form nucleosides, which, in turn, are components of nucleotides, with all of these monomers constituting the basic building blocks of nucleic acids.
3) purine nitrogenous bases:-
Purines and Pyrimidines are nitrogenous bases that make up the two different kinds of nucleotide bases in DNA and RNA. The two-carbon nitrogen ring bases (adenine and guanine) are purines, while the one-carbon nitrogen ring bases (thymine and cytosine) are pyrimidines.
pyrimidine nitrogenous bases
Pyrimidine: A nitrogenous base similar to benzene (a six-membered ring) and includes cytosine, thymine, and uracil as bases used for DNA or RNA.
The pyrimidine bases are thymine (5-methyl-2,4-dioxipyrimidine), cytosine (2-oxo-4-aminopyrimidine), and uracil (2,4-dioxoypyrimidine)
4) Explain Chargaff's rules for base -pairing
Chargaff's rules state that DNA from any species of any organism should have a 1:1 stoichiometric ratio of purine and pyrimidine bases (i.e., A+G=T+C ) and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine.
5)Identify what objects/colors you used for your DNA Model
The four nitrogenous bases that compose DNA nucleotides are shown in bright colors: adenine (A, green), thymine (T, red), cytosine (C, orange), and guanine (G, blue).
6)Twist your model and explain how it is a helix
Double helix is the description of the structure of a DNA molecule. A DNA molecule consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating groups of sugar (deoxyribose) and phosphate groups.
The double helix of DNA is, like its name implies, in the shape of a helix which is essentially a three dimensional spiral. The double comes from the fact that the helix is made of two long strands of DNA that are intertwined—sort of like a twisted ladder.

In conditioning, during the sequence of delaying the stimulus, the dogs often displayed____ anxiety or excitement
In conditioning, during the sequence of delaying the stimulus, the dogs often displayed anticipatory anxiety or excitement. Therefore, the correct option is (C).
During the sequence of conditioning, as the stimulus is delayed, dogs often display anticipatory anxiety or excitement. This phenomenon is known as the "anticipatory response" and is a form of classical conditioning. The dogs have learned to associate the delayed stimulus (e.g., the sound of a bell) with the upcoming reward or punishment. As a result, they exhibit a conditioned response, expressing their anticipation of the outcome even before the actual stimulus is presented.This anticipatory response is a crucial aspect of classical conditioning, demonstrating the learned association between the conditioned stimulus (the bell) and the unconditioned stimulus (the reward or punishment). It reflects the dog's ability to predict the forthcoming event based on their prior experiences and conditioning history.Therefore, the correct option is (C).
