Explanation:
Answer:
An ancestor, also known as a forefather, fore-elder or a forebear,[1] is a parent or (recursively) the parent of an antecedent (i.e., a grandparent, great-grandparent, great-great-grandparent and so forth). Ancestor is "any person from whom one is descended. In law the person from whom an estate has been inherited."[2]
Two individuals have a genetic relationship if one is the ancestor of the other or if they share a common ancestor. In evolutionary theory, species which share an evolutionary ancestor are said to be of common descent. However, this concept of ancestry does not apply to some bacteria and other organisms capable of horizontal gene transfer. Some research suggests that the average person has twice as many female ancestors as male ancestors. This might have been due to the past prevalence of polygynous relations and female hypergamy.[3]
Assuming that all of an individual's ancestors are otherwise unrelated to each other, that individual has 2n ancestors in the nth generation before him and a total of 2g+1 − 2 ancestors in the g generations before him. In practice, however, it is clear that most ancestors of humans (and any other species) are multiply related (see pedigree collapse). Consider n = 40: the human species is more than 40 generations old, yet the number 240, approximately 1012 or one trillion, dwarfs the number of humans who have ever lived.
Some cultures confer reverence to ancestors, both living and dead; in contrast, some more youth-oriented cultural contexts display less veneration of elders. In other cultural contexts, some people seek providence from their deceased ancestors; this practice is sometimes known as ancestor worship or, more accurately, ancestor veneration.

Which of the following best describes the structural relationship between genes, chromosomes and DNA?
A.Genes consists of two long strands of chromosomes, and each of these two strands consists of molecules called DNA.
B.Each DNA molecule consists of a number of pairs of genes, and each pair of genes on the DNA molecule is made up of chromosomes.
C.Each chromosome consists of number of DNA molecules, and each DNA molecule is made up of one to four different genes.
D.Each chromosome consists of a single long DNA molecule, and each gene on the chromosome is a particular segment of that DNA.
Answer:
D.Each chromosome consists of a single long DNA molecule, and each gene on the chromosome is a particular segment of that DNA.
Explanation:
A closed DNA molecule contains two strands of linear nucleotide sequences, and both DNA strands contain genes. These genes are DNA sequences that may be transcribed in messenger RNAs (mRNAs).
The cell nucleus contains chromosomes in which the double-stranded DNA molecules are packaged by specialized proteins (histones). Moreover, there are organelles (mitochondria and chloroplast) that also contain genes which are transcribed in an analog mode to genes contained in the nuclear chromosomes.
The correct statement is "Each chromosome consists of a single long DNA molecule, and each gene on the chromosome is a particular segment of that DNA"
Chromosomes are condensed strands or rings of DNA and have a double structure, composed of chromatids, in these the genes are located, in the same position with respect to their homologous.
Genes are found within chromosomes (which in turn make life in the nucleus of our cells).Each gene occupies a specific position, called a locus, along the gigantic chain of sequences that makes up DNA.Therefore, we can conclude that chromosomes are structures composed of DNA and genes are short segments of DNA, which is found within the chromosome always located in the same place.

The amino acids bond together to form which type of complex molecule?
1. Protein
2. Starch
3. Fat
4. Sugar
Answer:
Protein
Explanation:
Answer:
PROTIEN
Explanation:
Proteins are linear polymers formed by linking the α-carboxyl group of one amino acid to the α-amino group of another amino acid with a peptide bond (also called an amide bond). The formation of a dipeptide from two amino acids is accompanied by the loss of a water molecule (Figure 3.18).

As Darwin was developing his ideas about evoution, he applied ideas from many fields, including geology, economics, and biology. Why was this approach important?
Answer:
Explanation:
Darwin's use of many different fields of study including geology, economics, and biology was incredibly important as it allowed him to make connections between them that ultimately led to ground breaking discovery. Such as animals that that migrated to different areas and were interconnected through their geological footprints that were left behind.
Answer:
Darwin's theory of natural selection is important because it enables us to understand the forces driving evolution in living organisms. This evolutionary mechanism may also be used in different research fields ranging from molecular biology to economy.
The evolution theory states that the organisms that are better adapted to the environment have more chances to survive and to reproduce, thereby perpetuating their own genes in future generations. This idea of selection can also be applied to other disciplines. For example, in the economics field, it has been proposed that Darwin's theory may explain why those traits related to morality (such as fairness, honesty and integrity) which are beneficial for one particular group but not for the individual are not selected in real life.

Answer:Adenine always bonds with thymine, and guanine only bonds with cytosine. In RNA however, uracil (U) is substituted for thymine instead. So, in translation, adenine turns into thymine, and guanine turns into cytosine, and vice-versa. So, the complementary would be read as taagct
Explanation:
In which TWO ways will a dog contribute to the carbon cycle?
It will release carbon dioxide in the atmosphere through respiration.
It will take in carbon dioxide from the atmosphere.
Its feces will contain carbon that will enter the geosphere.
It will convert carbon to a form that will be used by plants for energy.
It will decompose the body of plants to release carbon dioxide.
Answer:
a and c
Explanation:
A dog can contribute to the carbon cycle in two ways, which are by releasing carbon dioxide into the atmosphere through respiration process and its feces contains carbon that will enter the geosphere. Therefore, option A and option C are correct statements.
What are the two ways of contributing to the carbon cycle by a dog?Dogs releases carbon dioxide during respiration process into the atmosphere, thereby, contributing to the carbon cycle. During cellular respiration, Dogs inhale oxygen and exhale carbon dioxide as a byproduct.
The feces of dogs also contain carbon that enters the geosphere. When dogs defecate, their waste contains carbon in the form of organic matter. The feces when decompose releases carbon dioxide into the soil which then enters the geosphere, thereby, contributing to the carbon cycle.
However, there are also other natural processes or human activities that play a very important role in the carbon cycle as compared to the dog activity, but still the role of a dog in contributing to the carbon cycle is measurable, and a big part of the carbon cycle.

Answer:
The other person is correct I did a test on plato and got it right. Shoutout to whoever it was that answered the question, I thank you!
Explanation:
The three types of muscle fibers are B) slow-twitch, intermediate-twitch, fast-twitch.
What are these muscle fibers?Slow-twitch fibers are also known as type I fibers. They are fatigue-resistant and have a high oxidative capacity. Slow-twitch fibers are used for activities that require endurance, such as long-distance running or swimming.
Intermediate-twitch fibers are also known as type IIa fibers. They are less fatigue-resistant than slow-twitch fibers, but they have a higher oxidative capacity than fast-twitch fibers. Intermediate-twitch fibers are used for activities that require both endurance and power, such as sprinting or jumping.
Fast-twitch fibers are also known as type IIb fibers. They are the least fatigue-resistant of the three types of muscle fibers, but they have a high glycolytic capacity. Fast-twitch fibers are used for activities that require short bursts of power, such as sprinting or weight lifting.

The definition of theory says that it is a hypothesis or group of hypotheses. In your own words, explain why a theory is also a hypothesis, using the definitions as a starting point. In your answer, provide an example of a theory that is a hypothesis supported by repeated experimentation.
Answer:
An in-depth illustration of a natural process that takes place in nature is termed as a scientific theory. After performing a scientific method the formation of a theory takes place. The generation of a good scientific theory takes place after proving, testing, and linking different kinds of ideas that are not just assumptions.
A theory can also be considered as a well-illustrated hypothesis as a scientific theory is a deeply illustrated and a well-substantiated idea that overpowers the restricted illustration of a suggested hypothesis. A theory is an amalgamation of various ideas.
The theory of relativity, which was postulated by Einstein in 1915 is a good illustration of a scientific theory that has been repeated several times. After the emergence in 1915, the theory was again examined in 1919 during the solar eclipse and was afterward examined and tested by different other scientists.

Estelle makes a Venn diagram to compare the fast- and slow-flowing areas of rivers and streams.
Which label belongs in the region marked X?
Fewer plants
Warmer
Cloudy water
Less oxygen
Image is not provided in the question, so the image is attached below.
Answer:
Fewer plants
Explanation:
The region X in Venn diagram represents fewer plants in the region.
As the regions marked X represents fast-flowing areas of rivers and streams which can be possible if the flow of water get less obstruction in its way, so if their will be fewer plants, river will get less resistance and can flow faster.
Other option do not affects the flow of water.
Hence, the correct option is fewer plants.
Answer:
Because lakes are often large and deep, little sunlight reaches the bottom. The lack of sunlight and resulting cold temperatures limit the number of plants that can grow beneath the water. Therefore, most of the plant growth in lakes is limited to shallow areas near the shore, where there is a lot of sunlight.
