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.

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.
The age of crustal rocks can be determined by the help of plate tectonics as the oldest rocks move away and deeper into the ridge.
How to determine age of crustal rocks?
Crustal rocks or Continental crust is the layer of igneous, sedimentary, and metamorphic rocks which are formed by the geological continents and the areas of shallow seabed that are close to their shores which is known as continental shelves.
The surface of continental crust mainly lies above the sea level, its existence allowed the land life to evolve from the marine life. Its existence can also provide broad expanses of shallow water known as epeiric seas and the continental shelves where complex metazoan life could become established during the early Paleozoic period, which is now called as the Cambrian explosion.
By using the magnetic polarity of the sea floor the age of crust rocks can be determined. Very little of the sea floor is older than 150 million years. This is because the oldest sea floor is subducted under other plates and replaces by new surfaces. Thus, the plate tectonics can help in determining the age of crustal rocks.

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.

How might the variety of traits affect the survival of the ladybugs?
Answer:
The variety of traits may cause the species of ladybugs to divert. Over time, if certain ladybugs were more adept at surviving on a certain plant or a different place, those ladybugs might survive, while others don't.
Another example is internal traits. For example, if pesticides that killed ladybugs were sprayed and there were some ladybugs that were resistant to it, more of those ladybugs would survive to reproduce.
Another impact could be the physical characteristics of the species. For example if there were yellow ladybugs and red ladybugs, and birds could see the yellow ladybugs better, since birds are predators of ladybugs, they could eat more of the red ladybugs. As a result, more red ladybugs would survive to pass on the gene that makes them red colored.
These are some examples. Hope this helps!

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.

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.

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.
