5. Explain how the discovery of Earth's true age, and the banning of leaded gasoline in the United States,
are connected?
Answer:
The best estimate for Earth's age is based on radiometric dating of fragments from the Canyon Diablo iron meteorite. From the fragments, scientists calculated the relative abundances of elements that formed as radioactive uranium decayed over billions of years.The U.S. Congress adopted the Clean Air Act in 1970 and created the U.S. Environmental Protection Agency. Effective January 1, 1996, leaded gasoline was banned by the Clean Air Act for use in new vehicles other than aircraft, racing cars, farm equipment, and marine engines.Explanation:
1. Which of the following statements best describes how genes relate to traits? a. Genes code for the production of specific proteins. These proteins lead to different traits. b. Genes and traits function together to produce proteins c. Traits contain instructions for making proteins, and genes are the observable outcome of such proteins. d. Genes are expressed according to instructions in traits.
PLS TELL ME THE ANSWER NOWWWWWW >:(
Genes code for the production of specific proteins. These proteins lead to different traits. The correct option is a.
What are traits?A trait, as it relates to genetics, is a unique feature of an individual. Genes, environmental factors, or a combination of both can influence traits.
Qualitative traits (such as eye color) and quantitative traits (such as height or blood pressure).
A gene is the most fundamental physical and functional unit of heredity. DNA is the building block of genes.
Some genes serve as blueprints for the creation of proteins. Many genes, however, do not code for proteins. Genes in humans range in size from a few hundred DNA bases to over 2 million bases.
Genes encode instructions for the production of specific proteins. These proteins result in various characteristics.
Thus, the correct option is a.

Is chromosome number a good predictor of organism complexity? Explain.
[PLEASE EXPLAIN WHY OR WHY NOT ALONG WITH YES OR NO]
Answer:
No, the number of chromosomes is actually barely related to complexity at all. For instance, humans have 46 chromosomes (2 sets of 23) whereas small deer have 6 chromosomes, and carp have over 100
Explanation:
PLEASE MARK ME AS BRAINLIEST
No, the number of chromosomes is not related to the complexity of an organism. For example, humans have 23 pairs of chromosomes while amoeba has 27 pairs of chromosomes.
What is a chromosome?They are thread-like genetic material present inside the nucleus. They are hereditary material, they pass from one generation to another. They are made up of deoxyribonucleic acid (DNA) and protein (histone protein). DNA is tightly coiled around the histone protein.
They carry all kinds of genetic information. They play important role in cell division, mutation, variation, regeneration, and heredity.
Different organisms have different numbers of chromosomes, humans have 23 pairs, fruit flies have 4 pairs, and yeast has 16 pairs of chromosomes. Therefore, their number does not have any correlation with the complexity of any organism.

Even though scorpions are related to spiders, there are many differences between the two organisms. One difference is that scorpion young do not hatch from eggs as spiders do. Scorpions are born live, two at a time, and they immediately crawl onto the mother's back for protection and care. They remain there for two weeks as they grow big enough to take care of themselves. The skin cells of a scorpion organize together to make a hard covering called a carapace, which helps protect the scorpion. Which term names a group of similar cells working together? Question 2 options: Organism Tissue Organ System
Answer:
The correct answer is - tissues.
Explanation:
The tissue is an organization of the cells to work together to perform a specific type of function in an individual organ or body system of an organism. The skin cells of the scorpion also organize together to play the role of hard covering that helps the scorpion to be protecting.
This organization of cells is known as carapace which is a tissue made up of cells together to protect scorpion as tissue is a group of similar cells working together.

An air mass forms over the water of the Gulf of Mexico and moves from the equator up toward us. What is it called?
Answer:
The word that describes humidity (maritime or continental) is paired with the word that describes temperature (equatorial, tropical, polar or arctic). For example, if an air mass forms over a tropical ocean, it is called maritime tropical. If an air mass forms over land in the far north it is called continental polar.

Its science! Give at least three sentences please and thank ya ill give brainliest Explain how precipitation happens. Use complete sentences and give at least two supporting details.
Answer:
Precipitation happens as a result of water evaporating and condensing. When water evaporates the water molecules transfer to a gas state into the atmosphere as water vapor. This water vapor then condenses due to cooler air temperatures because of this condensation larger water droplets form. Once these droplets become so large they can no longer be considered water vapor they will fall back down to earth. The act of these droplets falling is what is known as precipitation.

During DNA replication what occurs
Answer:
What happens during DNA replication?
How is DNA replicated? Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin.

Explanation:
Plants and animals that are very similar do toyear around one in the mositure.
Answer:
A.
Explanation:
Rainforests are forests characterized by high and continuous rainfall, with annual rainfall in the case of tropical rainforests between 2.5 and 4.5 meters and definitions varying by region for temperate rainforests.
Most rainforests are structured in four layers: emergent, canopy, understory, and forest floor.
Emergent Layer
The top layer of the rainforest is the emergent layer. Here, trees as tall as 60 meters (200 feet) dominate the skyline. Foliage is often sparse on tree trunks, but spreads wide as the trees reach the sunny upper layer, where they photosynthesize the sun’s rays. Small, waxy leaves help trees in the emergent layer retain water during long droughts or dry seasons. Lightweight seeds are carried away from the parent plant by strong winds.
Canopy Layer
Beneath the emergent layer is the canopy, a deep layer of vegetation roughly 6 meters (20 feet) thick. The canopy’s dense network of leaves and branches forms a roof over the two remaining layers.
Understory Layer
Located several meters below the canopy, the understory is an even darker, stiller, and more humid environment. Plants here, such as palms and philodendrons, are much shorter and have larger leaves than plants that dominate the canopy. Understory plants’ large leaves catch the minimal sunlight reaching beyond the dense canopy.
Forest Floor Layer
The forest floor is the darkest of all rainforest layers, making it extremely difficult for plants to grow. Leaves that fall to the forest floor decay quickly.
