1. What is the criteria necessary for organisms to be classified in the same species? (Choose all that apply)
A: offspring produced must look identical to the parents
B: must be capable of surviving in the same environmental conditions
C: offspring produced must be fertile
D: must be capable of interbreeding with one another
Answer:
c and D
Explanation:
Organisms who are capable of producing fertile offspring and can interbreed with one another are classified in the same species. Option (C) and (D) are correct.
What is classification of organism ?Classification in biology is the process of grouping species, both living and extinct, according to common traits. Taxonomy is the study of naming and categorizing living things. The word is a combination of the Greek words for arrangement and law, taxis and nomos.
A taxon is the term used to describe each group in biological categorization, or each level in the hierarchy (plural, taxa). A group of closely related organisms that can breed and generate children that can reproduce is known as a species, which is the most fundamental taxon.
Therefore, option (C) and (D) are correct option.

What do you think when you hear DNA? 13pts
Answer:
I think that DNA is like genetics, you share genetics (or you can call it DNA) with your family members, It's the genetic code that determines all the characteristics of a living thing. Basically, your DNA is what makes you, you! Each nucleotide contains a sugar and a phosphate molecule, which make up the 'backbone' of DNA, and, one of four organic bases.

Explanation:
Explain "Survival of the Fittest" and how it relates to natural selection.
"Survival of the fittest" is a popular term that refers to the process of natural selection, a mechanism that drives evolutionary change. Natural selection works by giving individuals who are better adapted to a given set of environmental conditions an advantage over those that are not as well adapted.
Answer:
the organisms that make it to the next generation are the fittest out of the natural selection
Explanation: Survival of the fittest refers to the one that makes it to the end of a race. So if an organism through natural selection has more offspring that make it to the next generation they are the "Survived of the fittest"

Heredity is the passing on of traits from parent to
offspring. Heritable information is important for life to
continue. What is the role of meiosis in heredity?
Explanation:
Perhaps the most fundamental property of all living things is the ability to reproduce. All organisms inherit the genetic information specifying their structure and function from their parents. Likewise, all cells arise from preexisting cells, so the genetic material must be replicated and passed from parent to progeny cell at each cell division. How genetic information is replicated and transmitted from cell to cell and organism to organism thus represents a question that is central to all of biology. Consequently, elucidation of the mechanisms of genetic transmission and identification of the genetic material as DNA were discoveries that formed the foundation of our current understanding of biology at the molecular level.

Genes and Chromosomes
The classical principles of genetics were deduced by Gregor Mendel in 1865, on the basis of the results of breeding experiments with peas. Mendel studied the inheritance of a number of well-defined traits, such as seed color, and was able to deduce general rules for their transmission. In all cases, he could correctly interpret the observed patterns of inheritance by assuming that each trait is determined by a pair of inherited factors, which are now called genes. One gene copy (called an allele) specifying each trait is inherited from each parent. For example, breeding two strains of peas—one having yellow seeds, and the other green seeds—yields the following results (Figure 3.1). The parental strains each have two identical copies of the gene specifying yellow (Y) or green (y) seeds, respectively. The progeny plants are therefore hybrids, having inherited one gene for yellow seeds (Y) and one for green seeds (y). All these progeny plants (the first filial, or F1, generation) have yellow seeds, so yellow (Y) is said to be dominant and green (y) recessive. The genotype (genetic composition) of the F1 peas is thus Yy, and their phenotype (physical appearance) is yellow. If one F1 offspring is bred with another, giving rise to F2 progeny, the genes for yellow and green seeds segregate in a characteristic manner such that the ratio between F2 pl

Answer: second
Explanation:Early humans most likely experienced changes in climate forcing migration to find animals for food, changes in climate alternating rivers with droughts and floods and changes in environment causing animal habits changes.
Explanation:
All the changes that early humans could have experienced, I think, are related to the changes that animals and the lands could have suffered. They lived much more closer to them than we do now; now we sometimes don't realize how global warming is affecting our planet because we are not that close to the lands and the crops and we don't usually raise animals for our consumption, we just buy at the shop. But, early humans could sense every change related with that because this was the way they lived. So, migration to find animals, changes in climate alternating rivers with droughts and floods and changes in animal habits are the ones I believe they could have suffered.

what are your thoughts about human population?
Answer:
As the human population continues to grow, the more resources we consume and use on earth. We need to slow it down, we highkey breeding like rabbits and in many places overpopulation is already a problem. As the population rises, all our problems we have grow as well. World hunger grows as there are more people on earth and we can't feed all of them. more people = more pollution.
Explanation:
Overpopulation is an undesirable condition where the number of the existing human population exceeds the actual carrying capacity of Earth. Overpopulation is caused by a number of factors. Reduced mortality rate, better medical facilities, depletion of precious resources are few of the causes which result in overpopulation. It is possible for a sparsely populated area to become densely populated if it is not able to sustain life.
Growing advances in technology with each coming year has affected humanity in many ways. One of these has been the ability to save lives and create a better medical treatment for all. A direct result of this has been the increased lifespan and the growth of the population.
In the past fifty years or so, the growth of the population has boomed and has turned into overpopulation. In the history of our species, the birth and death rates have always been able to balance each other and maintain a population growth rate that is sustainable.
At the root of overpopulation is the difference between the overall birth rate and death rate in populations. If the number of children born each year equals the number of adults that die, then the population will stabilize.
Talking about overpopulation shows that while there are many factors that can increase the death rate for short periods of time, the ones that increase the birth rate do so over a long period of time.
The discovery of agriculture by our ancestors was one factor that provided them with the ability to sustain their nutrition without hunting. This created the first imbalance between the two rates.
Fatal Effects of Overpopulation
1. Depletion of Natural Resources
2. Degradation of Environment
3. Conflicts and Wars
4. Rise in Unemployment
5. High Cost of Living
. Extinction
which is the one reason scientists produce transgenic organisms?
A. to control microorganisms in the soil
B. to treat certain types of diseases
C. to create new species of organisms
D. to prevent habitats from being destroyed
Answer:
its B
Explanation:
One reason scientists produce transgenic organisms is to treat certain types of diseases.
Transgenic organisms are known as all those living beings whose genetic material has been adulterated by human intervention as a result of genetic engineering.
This may involve artificial selection (the controlled crossing of species) or techniques for inserting genes into the genome of a species (known as transgenesis or cisgenesis).
They are used, to a greater extent, in the food industry (agriculture and livestock) and in medicine (for vaccines or to reverse or treat inherited diseases).For example, gene therapy, used to combat genetic diseases, consists of replacing a defective segment of individuals' DNA with a healthy copy, thus preventing congenital diseases from developing.Therefore, we can conclude that one reason scientists produce transgenic organisms is to treat certain types of diseases.
