17. Pedro and Denise were sharing a snack. Pedro drank some hot tea while Denise drank ice water. Which best explains the difference between the molecules in the hot tea and the ice water?
A. The molecules in the ice water move faster than in hot tea.
B. The molecules in the ice water move slower than in the hot tea.
C. The molecules in the hot tea have less energy than in the ice water.
D. The molecules in the hot tea have the same amount of energy as in the ice water.
Pedro and Denise were sharing a snack. Pedro drank some hot tea while Denise drank ice water: (B) The molecules in the ice water move slower than in the hot tea.
Why do molecules move slower in cold water?The molecules in hot and cold water are the same. Each molecule consists of one oxygen atom and two hydrogen atoms. The difference is the rate at which the molecules bounce about.
Because they contain energy, molecules are continually moving. Water molecules travel faster and are literally bouncing off one another when they are in a liquid state as opposed to a solid state. The quantity of potential energy in the liquid decreases as it cools, and the molecules begin to move more slowly.
Option (B) is the correct answer.

D. It packages all the genes in a living thing.HeLP asap please
DNA is a polymer composed of several nucleotides. Genes are the inheritable subunits that carry genetic information and are composed of a varying number of nucleotides. D) It packages all the genes in a living thing.
What is DNA?
DNA is the deoxyribonucleic acid. It carries all the genetic information needed for the organism to accomplish its functions.
This polymer is composed of several monomers known as nucleotides, which joined by their extremes compose the DNA linear molecule.
Genes are DNA fragments that transmit the information needed to specify traits and are inheritable. These fragments are transmitted as units from generation to generation.
Genes are located in the DNA molecule and are composed of varying numbers of nucleotides.
During the cell cycle, when DNA is lax, it is called chromatin. But when cell division occurs and DNA condensates it forms the chromosomes.
DNA is intimately associated with two types of proteins:
histones, which are structural proteins, and non-histone proteins, which mediate different functions of DNA.According to this framework, Option D is correct. It packages all the genes in a living thing.

Explain the ages of crustal rock using evidence of the past and current movements of continental and oceanic crust and the theory of plate tectonics.
Crustal rocks are found on the Earth's crust. Their age can be determined by measuring how far they have moved from the ridge.
What are Crustal rocks?Crustal Rocks are the rocks which are found on the earth's crust. The continental crust layer is made up of three different types of rocks. These rocks include Sedimentary, Metamorphic, and Igneous rocks.
Most of the crustal rocks are formed before 2.5 billion years ago and are located in cratons. Such an old continental crust is less dense than elsewhere in the Earth and are not readily destroyed by any kind of subduction.
These rocks get older as they move away from the ridge layer, indicating the crust is moving which is explained in plate tectonic theory. The oldest rocks could be found near the edges of the continent.

anyone know of any free anatomy classes i can take or free onlive live classes for all categories
Answer:
Answer below
Explanation:
Many states offer free virtual programs that allow you to co-enroll and access advanced courses for free. Check with your local virtual programs to see which ones you can qualify for.
If you are unable to attend virtual programs, then you can likely find a online service (it will not be live most the time) that can teach you. Channels like CrashCourse are good, but I believe Khan Academy also provides videos, articles, and practice tests on anatomy.

What does circulation look like in an newborn?
Answer:
During pregnancy, the unborn baby (fetus) depends on its mother for nourishment and oxygen. Since the fetus doesn’t breathe air, his or her blood circulates differently than it does after birth:
The placenta is the organ that develops and implants in the mother's womb (uterus) during pregnancy. The unborn baby is connected to the placenta by the umbilical cord.
All the necessary nutrition, oxygen, and life support from the mother’s blood goes through the placenta and to the baby through blood vessels in the umbilical cord.
Waste products and carbon dioxide from the baby are sent back through the umbilical cord blood vessels and placenta to the mother's circulation to be eliminated.

Maya lives near the sea and likes to have picnics with her friends on the beach. The beach is home to many gulls that carry the bacteria for the disease psittacosis. During one of these picnics, a gust of wind scatters sand and water, which is contaminated with gull droppings, into the air. Five days later, Maya and her friends all develop symptoms of psittacosis. Which mode of disease transmission could have infected Maya and her friends with the psittacosis bacteria?
A.
aerosol
B.
direct contact
C.
vector
D.
oral
Reset
Answer:
A. Aerosol
Explanation:
Aerosol transmission is when the pathogen is spread through the air, either by the transmission from the air to the person directly or by the pathogen being stored in the environment the infected organism was in.
Lets check the other answers just in case.
B. Maya and her friends did not directly contact the infected seagulls, so this is incorrect.
C. Vector transmission is by utilizing insects in order to transport the pathogen. While this was the cause of the bubonic plague, this is not the case for this transmission.
D. Oral is also not the answer, as they were not exposed by close contact with the infected seagulls. Unless they tried CPR on a seagull or ate an infected seagull, this is unlikely.

The genetic material is located in which part of the cell
Answer:
The Cell Nucleus
Explanation:
Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or (mtDNA). Mitochondria are structures within cells that convert the energy from food into a form that cells can use.
The cell's genetic material is contained in the nucleus.
Cells, frequently referred to as the "building blocks of life," make up all living organisms, ranging in number from the single cell of bacteria to the trillions in humans.
Each of these cells is a distinct entity enclosed in a cell membrane and containing a viscous liquid substance known as cytoplasm.
The majority of the DNA in human cells is located in a region of the cell called the nucleus. It's referred to as nuclear DNA.
DNA's primary role in a cell is to store the genetic data necessary for an organism to grow, function, and reproduce. Each creature is unique because of the information that is stored in its DNA and can be handed down from one generation to the next.
Therefore, the nucleus of the cell contains genetic material.

The inheritance pattern of one gene will not affect the inheritance pattern of another gene. This is known as (1 point)
O independent assortment.
O genetic variation.
O crossing over.
O random distribution.
Independent assortment occurs only in independent genes that are far away from each other. A) Independent assortment states that the inheritance pattern of one gene will not affect the inheritance pattern of another gene.
What is independent assortment?
Independent assortment is a law that establishes that the alleles from two or more different genes distribute in gametes independently from each other. In other words, a gamete receives an allele from a gene that does not depend on nor influence the allele of another gene in the same gamete. This can only be applied to independent genes.
Many genes segregate independently after crossing over because they are located far away from each other. But some other genes are too close and they do not segregate independently. These are the linked genes that do not exhibit an independent distribution, and they inherit together more frequently.
Option A is correct. Independent assortment states that the inheritance pattern of one gene will not affect the inheritance pattern of another gene.
