Answer:
erosion is the action of surface processes that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location. Erosion is distinct from weathering which involves no movement.
Some cnidarians are unique in exhibiting polyp and medusa forms. How might their two body forms give them an advantage over species that have only one body form?
Answer:
Explanation:
cnidarians are mostly marine animals. they exibit alternation of generation with two different body forms. their larval stage is polyp and the maturation stage is madusa. these two different forms help them to survive. polyp stage is sessile while medusa stage is free swiming. they can get food migrate and do sexual reproduction. their are also some cniderians that exhibit only one body form. these are less suited to environment as compared to the others that haae two body forms.

Which 2 events during meiosis increase GENETIC
VARIATION by ensuring that each egg and each
sperm will be unique?
Answer:
(three) crossing over, mutations caused during crossing over, and independent assortment.
Explanation:
Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote. Recombination or crossing over occurs during prophase I.

what is the probability that a mother with type O blood and a father with type AB blood will have a child with type B blood
Answer:
So, without being given any more information (like that another child is already A, B, or O) then there are 16 possible combinations that can be had, but only one of them is type O, so there’s a 6.25% chance the child could be O.

What is the source of energy behind the carbon cycle?
4
O decomposition
sun
O combustion
O consumers
Answer:
B. Sun.
Explanation:
The carbon cycle can be defined as the cycle in which carbon atoms travel from the atmosphere to earth and back to the atmosphere. As carbon is the source through which all life on earth exists.
The source of the carbon cycle is solar energy. During the process of photosynthesis, it is the sun that plays an integral role in taking carbon dioxide from plants.
Therefore, option B is the correct answer.
A forensics expert has obtained a sample of human blood from a crime scene. How can DNA fingerprinting be useful for identifying the person who left
the blood at the crime scene?
A by identifying the sequence of nucleotides in the DNA of blood cells
B. by comparing DNA from the blood cells with DNA from suspects
C. by identifying certain genetically controlled traits of suspects, such as eye shape and blood type
D. by comparing karyotypes made from blood cells at the crime scene and blood cells from suspects
Answer:
B - by comparing DNA from the blood cells with DNA from suspects!
Explanation:
DNA fingerprinting is a laboratory technique used to establish a link between biological evidence and a suspect in a criminal investigation.
A DNA sample taken from a crime scene is compared with a DNA sample from a suspect.
If the two DNA profiles are a match, then the evidence came from that suspect. (from www.genome.gov )
Hope this helps! :]
A forensics expert has obtained a sample of human blood from a crime scene, DNA fingerprinting may be useful by comparing DNA from the blood cells with DNA from suspects, which is option B.
What is DNA fingerprinting?DNA fingerprinting is a technique used to identify individuals based on their unique DNA profiles, and by analyzing the sequence of nucleotides in an individual's DNA, forensic scientists can create a DNA profile that is unique to that individual. So to identify the person who left the blood at the crime scene, forensic scientists would analyze the DNA in the blood sample and create a DNA profile, and then find out the criminal based on the DNA fingerprinting.
Hence, DNA fingerprinting may be useful by comparing DNA from the blood cells with DNA from suspects, which is option B.

What kinds of diseases can vaccinations prevent?
genetic diseases only
bacterial diseases only
viral diseases only
any infectious disease
Any infectious disease (genetic, bacterial, and viral) can be prevented by vaccinations. Therefore, option D is correct.
Vaccinations are primarily designed to stimulate the immune system and provide protection against specific pathogens that cause diseases. They work by introducing harmless components of the pathogen, such as inactivated or weakened viruses or bacteria, or their components (antigens), into the body.
This exposure allows the immune system to recognize and mount an immune response against the pathogen without causing the actual disease.

How can an organism's environment affect its traits?
First, I read that so incorrectly. Awkward.
An organism's environment affects its physical and self traits by making them adapt. Charles Darwin had discovered this theory with the finches. Places that were harder to get food would make these finches physical change over evolution to help them survive. It changes the animals habits depending on their resources. If a bird eats berries but there is no berries then the bird will have to change its diet or it will die.

C. It is more than 2.1 million years old.
D. It is exactly 1.4 million years old.
Answer:
B
Explanation:
It is less than 1.4 million years old
Based on the absolute dating of the rock layers in this photograph, a scientist could conclude about a fossil found in area A is that it is less than 1.4 million years old.
What do you mean by Fossils?Fossils may be defined as the dead and organic remains of the past organisms which are preserved deep in the soil over a long period ago.
The fossil found in area A is very recent from the evolution point of view. The deeper the layer, the oldest is the fossil.
Area A of the fossil is synthesized after the time period of 1.4 million years ago, hence the fossil present in that area would be less than 1.4 million years old.
Therefore, based on the absolute dating of the rock layers in this photograph, a scientist could conclude about a fossil found in area A is that it is less than 1.4 million years old.

Explanation:
A geneticist is trying to recreate a strand of DNA from a crime scene investigation. The strand of DNA recovered from the scene was 1800 bases long. The geneticist has determined that the strand contained 425 thymine
nucleotides. Based on this information, identify the number of cytosine nucleotides
Answer:
475
Explanation:
The strand is only made up of Adenine, Thymine, Cytosine and Guanine. There will be the same number of Adenine as there are Thymine and the same number of Cytosine as there are Guanine.
We know there are 425 Thymine. This means there are also 425 Adenine. Therefore, you would subtract 850 (425x2) from 1800 to find the amount of Cytosine and Guanine left, which is 950.
Out of the 950, half will be Cytosine and half Guanine. 950/2 is 475.
