Answer:
adaptations are the development of new characteristics that improve the survival and fitness of an organism. these adaptations comes from either mutation or recombination.
those organisms which have adapted can better survive and compete with the other members of population. in case of any disastrous change only those survive which have been adapted all others will die. these adaptation increase their struggle for existence.

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.

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.

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.

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.

Explanation:
Data from embyros can be used to help establish evolutionary relationships. True or false
Answer:
True
Explanation:
The study of the formation and development of the embryo is very useful in evolutionary biology in order to determine similarities derived from a common ancestor (i.e. homologies). In consequence, embryology is a discipline used to establish relationships between species and higher taxa. For example, vestigial organs and/or tissues (e.g., tails in humans) can be observed in the embryos during the first stages of development. In this regard, embryology has been an important aspect of the evolutionary theory proposed by Darwin (1859) by evidencing the process of species radiation from their ancient ancestors.
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.
