D. Complementary strands of mRNA
In transcription, RNA is made from RNA.
The final product of DNA transcription is complementary strands of mRNA.
What do you mean by transcription?Transcription is the process of copying a segment of DNA into RNA. The segments of DNA transcribed into RNA molecules that can encode proteins are said to produce messenger RNA. Other segments of DNA are copied into RNA molecules called non-coding RNAs.
During transcription, a piece of DNA that codes for a specific gene is copied into messenger RNA (mRNA) in the nucleus of the cell. The mRNA then carries the genetic information from the DNA to the cytoplasm, where translation occurs.
The purpose of transcription is to make RNA copies of individual genes that the cell can use in the biochemistry. The purpose of translation is to synthesize proteins, which are used for millions of cellular functions.

The Punnett square above shows a cross between two sweet pea plants in Mendel's greenhouse. Both parents have blue flowers (Bb). Which statement describes the offspring expected from this cross? A) 50% white-flowered and 50% blue-flowered B) 75% white-flowered and 25% blue-flowered C) 75% blue-flowered and 25% white-flowered Eliminate D) 100% blue-flowered and 0% white-flowered
Answer:
C) 75% blue-flowered and 25% white-flowered Eliminate
Explanation:
A square representation of a cross between the gametes of the parent allele for a specific trait is called a Punnett square. A cross between a single trait among the parental generation is called a monohybrid cross.
75% blue-flowered and 25% white-flowered is expected from this cross.
The Punnett cross between the flowers can be explained as:Given,
The allele for the blue parent plant = Bb
See the attached image below for the cross.
Phenotypic ratio = 2:1Genotypic ratio = 1:2:1The physical attribute of flower colour will be seen as 75 % blue coloured and 25% white coloured flower as the cross was between two heterozygous species.

Can nonrenewable resources be used sustainably?
A. Yes, nonrenewable resources are always beneficial for the environment
B. No, there are only negative effects of using nonrenewable resources
C. No, there's a finite amount of nonrenewable resources
D. Yes, as long as use doesn't exceed availability
is the correct answer
D. Yes, as long as use doesn't exceed availability
Answer:
C
Explanation:
we know non renewable resources once used up can't be replenished, the question of can it be used sustainably certainly does not present a good picture of its use. It is certainly more difficult to replace such resources.
D. Yes, as long as use doesn't exceed availability.
Nonrenewable resources, such as fossil fuels (coal, oil, natural gas) and minerals (like metals), are finite in nature and cannot be replenished over short timescales. However, they can be used sustainably if their extraction and consumption rate do not exceed their natural rate of formation or replenishment over geological timeframes.
Option D is the correct statement because it highlights the possibility of using nonrenewable resources sustainably by ensuring that their usage does not deplete them faster than they can naturally be replaced. Sustainable use involves managing the extraction and consumption of nonrenewable resources in a way that considers their finite nature, seeks efficiency in utilization, and promotes the development and adoption of alternative, renewable, or more sustainable energy and material sources.
On the other hand, options A and B are incorrect. Nonrenewable resources can have both positive and negative effects depending on their usage and management. While they have been essential in driving modern industrial development and economic growth, their use is associated with environmental impacts like greenhouse gas emissions, air and water pollution, habitat destruction, and climate change.
Option C is partly true as nonrenewable resources are indeed finite, and their quantities are limited. However, just because they are finite doesn't mean they cannot be used sustainably. Sustainable use involves making informed decisions about their utilization, maximizing efficiency, and exploring alternatives to ensure a balance between meeting current needs and conserving resources for future generations.

Which mineral test is shown in the image?
Hardness mineral test is shown in the image. The right answer is c.
The hardness of a mineral is a measure of its resistance to scratching or abrasion. It is one of the fundamental physical properties used to identify and classify minerals. The most commonly used scale for testing mineral hardness is the Mohs Scale of Hardness, which was developed by Friedrich Mohs in 1812.
The scale ranks minerals from 1 (the softest) to 10 (the hardest) based on their ability to scratch each other. Talc, with a hardness of 1, is the softest mineral and can be easily scratched by a fingernail while Diamond, is at the top of the scale with a hardness of 10, is the hardest mineral and can scratch all other minerals.

Which macromolecule forms a double layer as the primary structure of cell membranes?
A.fats
B.oils
C.phospholipids
D.steroids
Phospholipids form a double layer that acts as the primary structure of cell membranes. They align naturally in a bilayer due to their unique structure, where one part is attracted to water while the other part is repelled.
Explanation:The macromolecule that forms a double layer as the primary structure of cell membranes is phospholipids. These are a type of fat molecule that has a phosphate group in its structure. They have a unique property, where one part of the molecule is attracted to water (hydrophilic) and another part is repelled by water (hydrophobic). In a water-based environment, phospholipids naturally arrange themselves in a double layer, or bilayer, with their hydrophilic phosphate heads facing the water and their hydrophobic fatty acid tails tucked away in the middle. This double layer forms a barrier that separates the inside of a cell from its surrounding environment, hence forming the primary structure of cell membranes.

Four locations on Earth receive sunlight at different angles. At which of the following angles will the intensity of sunlight received be the least? 90° 75° 50° 25°
Answer:
25°
Explanation:
The Intensity of sunlight is greatest when the sun is overhead, that is when the sun is directly above, thus the rays strike the surface at right angles. In this way the intensity of sunlight will be concentrated over a smaller region compared to when the rays strike the surface at a much smaller angle like 25 degree.
Answer:
25°
Explanation:
The intensity of solar reaches the earth with greater intensity when the sun is in a position that allows the sun's rays to reach the earth at right angles. This is possible when the sun is well above the earth, at a 90º angle. The farther from this angle, the lower the intensity of the sun's rays on the earth, in that house, when the sun is at 25 ° the intensity of the sunlight received will be less.

Decide whether each statement describes the life cycle of a low-mass star or a high-mass star.
When a _____-mass star leaves the main sequence, it becomes a red giant before creating a planetary nebula and becoming a white dwarf.
When a _____-mass star leaves the main sequence, it becomes a red supergiant before creating a supernova and becoming either a neutron star or black hole.
Answer:
For the first blank ; low
For the second blank ;high
Explanation:
When a low-mass star leaves the main sequence, it becomes a red giant before creating a planetary nebula and becoming a white dwarf.
When a high-mass star leaves the main sequence, it becomes a red super-giant before creating a supernova and becoming either a neutron star or black hole.
Answer: "Low mass star" and 'High mass star"
Explanation: A low mass star is one whose mass is less than half of the sun's entire mass. Here, the size is very small, temperature is very much cold and exist for a quite long period of time. It eventually dies out becoming a white dwarf, after exiting the main sequence.
A high mass star is the one whose mass is thrice more than the sun's entire mass. Here, the size is very big, temperature is significantly high and exist for a shorter period of time. It subsequently becomes a reddish colored enormous star and dies out forming a black hole or it could form a neutron star, after coming out of the main sequence.

What is a difference between systemic and pulmonary circulation? A. Systemic circulation carries oxygenated blood to the lungs and pulmonary circulation carries deoxygenated blood to the body. B. Systemic circulation carries deoxygenated blood to the lungs and pulmonary circulation carries oxygenated blood to the body. C. Systemic circulation carries deoxygenated blood to the body and pulmonary circulation carries oxygenated blood to the lungs. D. Systemic circulation carries oxygenated blood to the body and pulmonary circulation carries deoxygenated blood to the lungs.
Your answer would be D, Systemic circulation carries oxygenated blood to the body and pulmonary circulation carries deoxygenated blood to the lungs.
These two circulations are part of the circulatory system, with the pulmonary circulation taking deoxygenated blood to the lungs and returning it oxygenated with the oxygen we breathe in, then that oxygenated blood going around the body delivering that oxygen and coming back deoxygenated.
Hope this helped!
In pulmonary circulation, deoxygenated blood is pumped from the heart's right ventricle, while in systemic circulation, oxygenated blood is pumped from the heart's left ventricle. thus option D is correct.
What are pulmonary and systematic circulation?Pulmonary circulation begins with the right ventricle sending deoxygenated blood to the lungs, where it is oxygenated before returning to the heart in the left atrium. while in the systemic circulation, oxygenated blood is pumped from the heart's left ventricle.
The pulmonary circulation's major purpose is to exchange gases (CO2 and O2) between the blood and the air.
The vascular system that distributes blood from the left ventricle to all of the body's tissues is known as systemic circulation.
The systemic circulation is in charge of maintaining a consistent blood flow via the capillaries in order to facilitate nutrient diffusion.
Finally, deoxygenated blood is pumped from the right ventricle of the heart in pulmonary circulation, whereas oxygenated blood is pushed from the left ventricle in the systemic circulation.

B Sea stars are the prey of seagulls.
O
C
Sea stars are the predators of seagulls.
D Sea stars are the hosts of seagulls.
Answer:
B. Sea stars are the prey of seagulls
Explanation:
Seagulls eat sea stars, meaning that sea stars are their prey (the organism that is eaten).
Predator: an organism that eats (preys on) another organism
Prey: an organism that is eaten by another organism (creatures can be both predator and prey. For example, a rabbit is a predator to grass, while they are prey to foxes)
Host: An organism that is fed on by a parasite. Think of a dog with a tick. The dog is the host, the tick is the parasite.
Incorrect answers (and why):
A. Sea stars do not eat seagulls
C. If a sea star was a predator to a seagull, that would mean that they eat seagulls. They do not.
D. A host is an organism that a parasite preys on. Not only are sea stars not parasites, but they definitely do not prey on seagulls.

2.) Would a plant grow better in a room painted blue or in a room painted green? Explain your answer.
Answer:
A blue room
Explanation:
Green light is the least effective for plants because they are themselves green due to the pigment Chlorophyll.. Blue light helps encourage vegetative leaf growth, and red light encourages flowers. this happens because the amount of blue, red and far red spectrum of light that reaches the planet changes with the seasons. As days start to get longer, more blue spectrum light reaches the surface of the earth. This initiates a vegetative growing stage for most plants leading into the spring and early summer. As the days start to grow shorter, and more of the red and far red spectrum reaches the surface, it leads into the late summer and fall reproductive season.

Which image models the action of the enzyme helicase in the DNA replication process?
The action of the enzyme helicase in the DNA replication process can be best represented by a zipper. Therefore option B is correct.
Helicase is responsible for unwinding the double-stranded DNA helix by breaking the hydrogen bonds between the complementary base pairs.
Like pulling apart the teeth of a zipper, helicase separates the two DNA strands, exposing the template strands for replication.
This unwinding is a crucial step as it allows the DNA replication machinery to access the individual strands and create new complementary strands.
The analogy of a zipper accurately captures the dynamic and sequential nature of helicase's role in DNA replication.
Therefore option B is correct.
