If Adam and Eve were the only people on earth first ,then does that mean every one is like your 5,000th cousin?
Answer:been isolated for more than 1250 years (which would render the proposition false at a conservative rate of 4 generations per century)? Quite possibly. They don’t, for example, have any form of agriculture or even a means to make fire, and their language is unintelligible. Chances are you have no recent (a few hundred, generations at least) Sentinelese relatives.

Answer:
Mitosis
Explanation:
Rabbits and sheep both graze on shrubs, grasses, and other plants. The sharp rise in the population of rabbits in a region may result in a shortage of plants for sheep to graze upon.
This relationship between sheep and rabbits is an example of _______.
A.
parasitism
B.
predation
C.
commensalism
D.
competition
The answer is D) competition.
We can see from the problem that the two animals are competing with one another. As the number of rabbits increases, the competition between the food source increases. This is why predators are important for the environment, as the level out the playing field for both animals.

What evidence of climate change on continents supports the theory of continental drift?
signs that glaciers existed in South Africa
similar coal fields on different continents
change in atmospheric temperature over time
same animal fossils found on different continents
Answer:
A
Explanation:
Edge2022
The evidence of climate change on continents that supports the theory of continental drift is similar coal fields on different continents. Hence option B is correct.
What is continental drift theory?The theory of continental drift suggests that the Earth's continents were once joined together in a single landmass called Pangaea, which began to break apart around 200 million years ago.
This idea was first proposed by German scientist Alfred Wegener in the early 20th century, who noticed the striking similarities between the coastlines of Africa and South America.
Coal is formed from the remains of plants that lived millions of years ago, and its distribution can provide clues about how continents were once connected.
Coal fields found on different continents that match in age and composition indicate that the continents were once joined together in a larger landmass.
This supports the theory of continental drift, which states that the continents were once part of a single supercontinent that later broke apart and drifted into their present positions.
This evidence suggests that coal-forming swamps once existed in locations that are now separated by oceans and that these locations were once connected.
Hence option B similar coal fields on different continents is correct.

Scientists often use fruit flies as a method to test hypotheses about human genes. Why are fruit flies advantageous in the study of human inheritance?
They can self-pollinate.
They lack nucleic acids.
They are very different from humans.
They reproduce quickly and take up little space.
Fruitflies are advantageous in the study of human genes and inheritance because they reproduce quickly and take up little space.
Advantages of using Fruitflies in the study of human geneticsFruitflies are usually a subject for the study of human genes and inheritance for some reasons:
They have a simple genetic structureThey reproduce quicklyThey are quite small and hence take up very little spaceThe quick rate of reproduction makes fruitflies good subjects for studying mutation as well.

They reproduce quickly and take up little space.
What is inheritance?Fruit flies (Drosophila melanogaster) are advantageous in the study of human inheritance because they have several characteristics that make them well-suited for genetic research. One key advantage is their rapid reproductive cycle, with a generation time of about two weeks. This allows researchers to observe multiple generations in a short period, accelerating the study of inheritance patterns and genetic traits.
Additionally, fruit flies have a relatively small size, making it feasible to maintain large populations in a laboratory setting without requiring excessive space or resources. This allows for efficient experimental design and the ability to conduct large-scale genetic studies.
While fruit flies share some genetic similarities with humans, they are not identical to humans. However, their genetic and developmental processes have enough similarities to provide valuable insights into fundamental principles of inheritance and gene function, which can inform our understanding of human genetics.

what is the effect of telomere caps on cancer cells?
The telomere caps help to maintain genome integrity. In consequence, these repetitive sequences are fundamental to avoid the generation of cancer cells.
Cancer cells are a type of cells that proliferates in an uncontrolled manner, which is generally associated with mutations in the genome capable of altering normal gene expression patterns.
Telomere caps are repeated nucleotide sequences found at the end of chromosomes, which help to maintain genome integrity.
The elimination of these repetitive sequences (telomere caps) due to successive cell divisions triggers chromosomal (genome) instability and thus contributes to the emergence of genomic rearrangements that may lead to carcinogenesis.

why do heart cells have a higher percentage of mitochondria than liver and pituitary gland cells?
Answer:
This is because the heart requires large amounts of energy in order to pump blood to the rest of the body. The mitochondria produces ATP for energy, thus heart cells contain a higher percentage of mitochondria for energy to pump blood.
The heart cells have a higher percentage of mitochondria than liver and pituitary gland cells because the heart requires large amounts of energy in order to pump blood to the rest of the body. The mitochondria produces ATP for energy, thus heart cells contain a higher percentage of mitochondria for energy to pump blood.
What is the role of mitochondria in producing energy?The role of Mitochondria in producing energy are in charge of producing energy as ATP. The heart muscle has the highest energetical requirements. Several mitochondria compose these muscle cells because too much energy is needed to pump blood constantly.
Mitochondria are known as the one of the biggest organelles in the cell. They are semi-autonomous organelles surrounded by a double membrane that reproduce by binary fission and contain their own DNA, RNA, and ribosomes. Mitochondria are in charge of aerobic cell respiration, the process by which cells use organic compounds and turn them into energy.
Therefore, The mitochondria produces ATP for energy, thus heart cells contain a higher percentage of mitochondria for energy to pump blood.
