Darwin hypothesized that new species could appear gradually through small changes in an ancestral species. What experiment did he conduct to test this hypothesis?
Answer:
Darwin conducted an experiment with breeding pigeons.
Explanation:
The pigeons provided the perfect animal to test his theory of selection for quite a number of reasons including its trait diversity from wing structures to color patterns to size to flight patterns. From these experiments he concluded that by natural selection of randomly occurring traits that make species better suited for survival and reproduction, evolve in the astounding diversity of organisms on Earth today.

Does the volume increase with trial number, decrease with trial number, or stay about the same? Explain why you think the results are the way there are. There are many possible reasons for the data trend you see. Give some that you think are reasonable.
Hi. You have not informed the experiment that this question refers to and this makes it difficult for your question to be answered. However, I researched your question on the internet and was able to find a question like yours that featured an experiment that assesses the volume of balloons that have been inflated by people's breath.
With the reading of the experiment, we can see that the volume of the balloons remains the same through the number of tests. This is because our lungs tend to express the same amount of air when we blow, just as we tend to breathe the same amount of air in normal situations. This probably happened because all the balloons were filled with air, while the individuals were in the same physical and mental state, that is, they were relaxed and still, which did not change the amount of air they breathed and expelled. This volume of air would be different if the participants in the experiment were exerting some physical effort or were stressed and anxious.

Which process results in the formation of structure X?
A) mitosis
B) meiosis
C) recombination
D) cloning
The process that leads to the formation of structure X in the diagram would be meiosis.
The diagram is that of the female's reproductive structure showing the uterus, ovary, and fallopian tubes.
The structure marked X is an ovum or egg.The ovary produces ovum or eggs through a division known as meiosis.The ovary is diploid (2n), but gives rise to haploid (n) eggs by meiotic division. Thus, meiosis is referred to as reductional division.

Which statement describes seismic waves?
Answer:
Seismic waves are the waves of energy caused by the sudden breaking of rock within the earth or an explosion. They are the energy that travels through the earth and is recorded on seismographs. There are several different kinds of seismic waves, and they all move in different ways.
Three reasons that might have influenced authorities in the department of agriculture to use a higher percentage of Nguni on the communal and emerging sector of livestock farmers in South Africa in 2003
Answer:
Tolerance to heat, light and parasite.
Explanation:
Characteristics of tolerance to heat, light and parasite are the three reasons that might use a higher percentage of Nguni on the sector of livestock farmers in South Africa in 2003. The temperature of South Africa is extremely high which can be tolerated by the Nguni cattle due to its good characteristics. The Nguni cattle can bear extreme temperature, high intensity of light and resistance to parasites make it best suited for that environment.

All life shares the same evolutionary heritage from an ancestor that appeared 3.8 billion years ago.
A. True
B. False
Answer:
A. True
Explanation:
The last universal common ancestor or last universal cellular ancestor (LUCA), also called the last universal ancestor (LUA), is the most recent population of organisms from which all organisms now living on Earth have a common descent—the most recent common ancestor of all current life on Earth.

The survival of a living organism occurs when what?
Answer:
Every organism has a unique ecosystem within which it lives. This ecosystem is its natural habitat. This is where the basic needs of the organism to survive are met: food, water, shelter from the weather and place to breed its young. All organisms need to adapt to their habitat to be able to survive.

Without knowing the genetic differences of the birds, how can we know that cardinals and finches are likely more closely related to each other than cardinals and finches are to woodpeckers? Cardinals and finches live in more similar habitats. There is no difference in their relatedness; because they are all birds, they all evolved at the same time from a common ancestor. Cardinals and finches have more morphological similarities. Fossil records show that cardinals have been around longer than woodpeckers and sparrows.
Answer:
The correct answer is - Cardinals and finches have more morphological similarities.
Explanation:
To find out the relatedness of the different species or organisms one can use genetic mapping to find precise relatedness, however, if one can not find the genetic differences of the organism one can use the morphological similarities and differences to find out how closely they are related.
Homologous structures and analogous structures are two major morphological characters to find how closely related cardinals and finches are than cardinals and finches are to woodpeckers.

7. What biological process occurs after there has been a disturbance such as a flood, or a tornado-in an established ecosystem?
Answer: Ecological disturbance, an event or force, of nonbiological or biological origin, that brings about mortality to organisms and changes in their spatial patterning in the ecosystems they inhabit. Disturbance plays a significant role in shaping the structure of individual populations and the character of whole ecosystems.

Which region in the brain we can find the Neural stem cells? --> Are they SGZ ( Subgranular Zone) and SVZ( Subventricle Zone)?
Answer:
Subgranular Zone.
Explanation:
Subgranular Zone is the region in the brain where neural stems are located. These neural stem cells are found in two zones of the dentate gyrus which is a part of the hippocampus in the brain, as well as in the striatum that is the part of the basal ganglia located deep within the cerebral hemispheres. So according to this information we can conclude that Subventricle Zone is the region where Neural stems cells are not located.
