The diagram below shows a stack of rock layers. These layers have not changed position since they formed. Examine the diagram and answer the question that follows. If the age of Layer 4 is 400 million years and the age of Layer 1 is 500 million years, then the age of Layer 3 is A. older than 500 million years. B. between 400 million and 500 million years. C. 500 million years. D. younger than 400 million years.
The age of layer 3 will be between 400 million and 500 million years. Therefore, option (B) is correct.
Why rock dating is important?Finding estimates of the ages of rocks is essential for identifying the speeds of geological processes as well as the history of geological occurrences. Some rocks may be used to determine the relative sequence of events. The most well-known methods are uranium-lead dating, potassium-argon dating, and radiocarbon dating.
Radiometric dating, which considers the ratio of two distinct isotopes in a sample, establishes the age of rocks. Geologists may use tools like these to assess the age of a material since radioactive isotopes degrade over a predictable period of time. mass spectrometer for thermal ionisation

Which statement best describes the relationship between protein, amino acids, and DNA? (1 point)
O DNA codes for proteins. Proteins are made up of amino acids.
O Amino acids code for DNA. DNA is made up of protein.
O DNA codes for amino acids Amino acids are made up of proteins.
O Amino acids code for protein. Protein is made up of DNA.
Answer:
Explanation:
The major relationship between protein and nucleic acid is the reproduction of DNA which contains the information on how cells are used together with RNA which helps to make protein. Both nucleic acid and protein they have four biomolecules which are common in both of them.
Short answer: Using a binary code, genes (DNA) specify how proteins (among other things) are to be synthesized.
Analogy: If DNA is a cooking book, genes are recipes, and proteins the dishes resulting from processing the recipe ingredients.
The relationship between protein, amino acids, and DNA is defined by the DNA codes for proteins. Proteins are made up of amino acids.As DNA codes for proteins.
DNA, RNA, and protein are all intently related. DNA carries the records vital for encoding proteins, even though it does now no longer produce proteins directly. RNA includes the records from the DNA and transforms that records into proteins that carry out maximum cell functions.
What is DNA function?The essential process of DNA is to make the proteins that residing matters want to grow.
Thus it is well explained.

A dominant gene that codes for white hair is represented by the symbol W. If a parent with the genotype WW is crossed with a parent of genotype Ww, what percent of their offspring will have white hair?
A. 25%
B. 50%
C. 75%
D. 100%
Answer:
D
Explanation:
Seeing as the gene is dominate, the hair would still be white evening it's Ww. For the hair to be a different color both parent would need a recessive gene (w), though neither does, meaning all the kids would have white hair.

might Nation A have trouble getting that resource from Nation B?
Why is energy conservation beneficial?
List 5 ways that natural resources can be conserved.
Answer: Nation A might be overusing their natural resources causing them to need it from Nation B. However Nation B knows this which might cause Nation A the trouble of getting that source.
1. To force laws in preventing the overuse of natural resources
2. Making recycling must be necessary and used.
3. Making electric cars and putting gas restrictions.
4. To create forests in certain areas making sure laws prevent people from cutting it down.

In animals sexual reproduction requires
Answer:
The placement of sperm within female's reproductive track.
Explanation:
In animals, sexual reproduction requires sperm of male has to be placed in the reproductive track of female where eggs are present. The sperm of male fuse with eggs of female produces zygote which turns into an offspring. The sperm of male and egg of female are haploid in nature means having half number of chromosomes but when they fused together then the zygote which is formed is diploid i.e. double number of chromosomes. The gametes are formed through meiosis not mitosis. Mitosis cell division occur in body cells.

In an effort to maintain homeostasis, the organ systems of the human body work to keep the body's internal water level constant. Which of the following statements describe how the human body responds when its internal water level drops too low?
(I’ll give brainliest)
A. The skeletal system produces more circulating blood cells that insecure the body’s water intake
B. The excretory system signals the kidneys to retain more water and produce more concentrated urine to decrease water loss.
C. The nervous system signals the muscles to constrict , holding more water in the digestive track and decreasing water loss .
D.The excretory system signals the kidneys to release more water into the bladder to increase water loss .
Answer:
B.
Explanation:
When we are dehydrated, our urine tends to be more yellow, right? That's because our urine contained less water to dilute the chemical compounds causing the yellow color — when we're dehydrated, our kidneys decide to pull less water out of the bloodstream than normal.

The correct answer is A. The brain realizes that a ball is coming toward you.
Explanation
The optical components of the eye are those that allow the formation of the image on the retina and are the following: the cornea, the lens, the pupil, the aqueous humor, and the vitreous humor that allow the formation of an image on the retina.
