Dendrochronology, or tree-ring dating, provides absolute dates in two different ways: directly, and by calibrating radiocarbon results. Cross-dating determines the age of undated wood by directly matching ring patterns with trees of known age.

What is the primary focus of evolutionary psychology?
a. The universal patterns of behavior and cognitive processes that are different between humans and animals
b. The universal patterns of behavior and cognitive processes that stay the same over time
C. The universal patterns of behavior and cognitive processes that are similar between humans and animals
d. The ways in which universal patterns of behavior and cognitive processes have evolved over time
Answer:
I believe the answer is D. The ways in which universal patterns or behavior and cognitive processes have evolved over time.
The primary focus of evolutionary psychology is the ways in which universal patterns of behavior and cognitive processes have evolved over time. The correct option is D.
What is evolutionary psychology?Evolutionary psychology is the study of behavior, thought, and emotion through the evolutionary biology lens.
According to evolutionary psychologists, all human behaviors are influenced by physical and psychological predispositions that helped human ancestors survive and reproduce.
Evolutionary psychologists believe that the human brain evolved in response to specific problems that early humans faced.
One central tenet of evolutionary psychology is that understanding modern human behavior requires considering the environment in which early humans evolved.
The study of how universal patterns of behavior and cognitive processes have evolved over time is the focus of evolutionary psychology.
Variations in cognition and behavior would affect an individual's ability to reproduce and pass on those genes to their offspring.
Thus, the correct option is D.

Heredity is the transfer of genetic information from one generation to anther.
Explanation:
The statement that best describes heredity is ''Heredity is the transfer of genetic information from one generation to anther.'' Genetic information can be transfer from one generation to another through the process of reproduction in which the sperm of male fuse with egg of female with each other forming zygote that have some characteristic of male parent and some of female parent.

I personally think that all the methods could potentailly work but I would have to go with "A" as usaully GPS's are used as they are more simple and easier to have in a collar, as radio technology is probably the number one most used by people such as scientists
What is does the Law of Dominance state?
3. PI of a protein is dependent on the number of acidic and basic amino acid residues in the protein.
Answer:
The study of proteins is important because all the genes in cellular DNA house the program or code for a unique protein structure.
Explanation:
Within the science parlance, pl is the short way to write Isoelectric Point. It is the pH (that is the acidity or basicity) of a solution at which the net charge of a protein becomes nil.
The surface, in most cases, is likely going to be negatively charged when the pH of that same solution is above the pl. When this occurs, molecules that have similar negative charges will tend to move away or be repelled.
It is useful to note that the structure of proteins comprises of 20 amino acids all of which are connected by peptide bonds.

Which of the karyotypes shown is from a normal female?
A
B
C
D
Answer: c
Explanation:
Females have two X chromosomes and males have an x and a Y chromosome. The Y chromosome is significantly shorter because it doesn’t carry as many genes. C is the only option that has two X chromosomes
The karyotype of a normal female is in diagram c. The correct option is c.
What is a karyotype?A karyotype is an individual's complete set of chromosomes. The phrase might refer to an image created in a lab showing a person's chromosomes separated from each individual cell and organized in numerical order.
If a person has a mutation, the karyotype can tell whether they are a man or a mulcher. This is so because a person's chromosomes are represented by a karyotype.
A 23-pair karyotype, one of which is made up of sex chromosomes that are XY for males and XX for women, is required for a person to be considered to be mutation-free.
Males have an x and a Y chromosome, while females have two X chromosomes. The Y chromosome is considerably smaller because it contains fewer genes. The only choice with two X chromosomes is C.
Therefore, the correct option is C.

Which of the following is a correct DIFFERENCE between sexual and asexual reproduction?
A. Sexual Reproduction creates genetically different offspring.
B. Sexual Reproduction creates genetically identical offspring.
C. Asexual Reproduction creates genetically different offspring.
D. Asexual Reproduction creates no offspring.
Answer:
A. Sexual Reproduction creates genetically different offspring.
Explanation:
Sexual Reproduction is created through 2 different opposite parties, in which the product takes around half of the genes from each individual parties. The traits that are shown are then decided on whether or not they are dominant or recessive or non-existent.
In a Asexual Reproduction, the reproductive capabilities of both parties are found inside one organism. The organism is able to produce both the sperm and egg, and therefore do not need a partner to reproduce. This means that the DNA inside the body is the only source for production, and that there will be very little variation in the DNA.
~
Asexual reproduction involves one parent and produces offspring that are genetically identical to each other and to the parent. Sexual reproduction involves two parents and produces offspring that are genetically unique

Transcribe the DNA sequence into mRNA: TAC CCA AGT

Answer:
AUG GGU UCA
i think im not sure
umm im trying to figure it out tho i think its A
Explanation:
Answer:
AUG GGU UCA
Explanation:
To transcribe the sequence, we first must find the complementary sequence of the DNA sequence. To do this, we must know that "A" pairs with "T", and "G" pairs with "C". What this means is we replace A with T,G with C, and vice versa. We get ATG GGT TCA. Now all we have to do is replace all the "T"'s with U's as Thymine is replaced by Uracil in RNA. Doing this we get AUG GGU UCA, which is the answer.
