The term population dynamics would not be used to describe which of the following examples?
Α.
birth rates
B.
changes in population size
death rates
success of offspring reaching reproductive age
Answer:
Population size is influenced by the per capita population growth rate, which is the rate at which the population size changes per individual in the population. This growth rate is determined by the birth, death, emigration, and migration. Pretty much Birth rate or Death rate.

identify one organism from each of the six periods of the paleozoic era
Answer:
The Paleozoic is divided into six periods: the Cambrian, Ordovician, Silurian, Devonian, Carboniferous (in the U.S., this is divided into the Mississippian and Pennsylvanian Periods), and Permian. Most of these names derive from locations where rocks of these ages were first studied.

Give three reason why specialized systems are necessary in large multicellular organisms
Answer:
Specialized systems are necessary in large multicellular organisms since 1. there is a division of labor between cells, 2. many individual cells cannot work together without coordination, and 3. most of the cells are not in direct contact with the outside environment

Describe the relationship between the sickle cell phenotype and hemoglobin’s structure and function
Answer: Explanation:
Sickle hemoglobin differs from normal hemoglobin by a single amino acid: valine replaces glutamate at position 6 on the surface of the beta chain. Therefore the red blood cell bends differently giving it a sickle shape
Answer:
Explanation:
Sickle cell disease is a group of disorders that affects hemoglobin, the molecule in red blood cells that delivers oxygen to cells throughout the body. People with this disease have atypical hemoglobin molecules called hemoglobin S, which can distort red blood cells into a sickle, or crescent, shape.
Signs and symptoms of sickle cell disease usually begin in early childhood. Characteristic features of this disorder include a low number of red blood cells (anemia), repeated infections, and periodic episodes of pain. The severity of symptoms varies from person to person. Some people have mild symptoms, while others are frequently hospitalized for more serious complications.
The signs and symptoms of sickle cell disease are caused by the sickling of red blood cells. When red blood cells sickle, they break down prematurely, which can lead to anemia. Anemia can cause shortness of breath, fatigue, and delayed growth and development in children. The rapid breakdown of red blood cells may also cause yellowing of the eyes and skin, which are signs of jaundice. Painful episodes can occur when sickled red blood cells, which are stiff and inflexible, get stuck in small blood vessels. These episodes deprive tissues and organs, such as the lungs, kidneys, spleen, and brain, of oxygen-rich blood and can lead to organ damage. A particularly serious complication of sickle cell disease is high blood pressure in the blood vessels that supply the lungs (pulmonary hypertension), which can lead to heart failure. Pulmonary hypertension occurs in about 10 percent of adults with sickle cell disease.
A class is debating the advantages and disadvantages of different types of reproduction. One student argues that organisms that reproduce asexually, like bacteria, have no advantage over organisms that reproduce sexually.
Which of the following choices below represents an argument for the advantages of asexual reproduction?
A. Organisms that reproduce asexually are likely to find a mate at a faster rate than sexually reproducing organisms, which allows them to reproduce faster.
B. Organisms that reproduce asexually are more diverse and are more likely to pass on key genes for survival to future generations, which aids in maintaining beneficial genes for survival in the gene pool
C. Organisms that reproduce asexually gain variation through processes like crossing over, which allows survival in instances of ecological change
D. Organisms that reproduce asexually create a large amount of offspring in a short period of time in order to maintain their population
Answer: D. Organisms that reproduce asexually create a large amount of offspring in a short period of time in order to maintain their population.
Explanation:
When an organism is able to reproduce asexually as opposed to sexually, it means that they do not require a mate to make offspring. Offspring of such organisms will therefore receive all their genes from one source.
Such organisms are able to reproduce very fast when they are presented with adequate conditions especially because they do not need another organism to do so. They will neither have to waste much energy nor have to go through the whole sexual process so they will be able to produce lots of offspring.
Animals are known to have offspring through asexual and/or sexual reproduction. The choices that has an argument for the advantages of asexual reproduction is that Organisms that reproduce asexually create a large amount of offspring in a short period of time in order to maintain their population.
Asexual reproduction is simply known as a type of reproduction where offspring are genetically identical to the parent.The offspring are regarded as clones that derives its root from the original parent.
A single individual can have offspring asexually and also in large numbers quickly.

How did scientists begin to Mark divisions in the geologic time scale in response to a change they discovered in the geologic record
Answer:
Scientists began to mark division on the geologic time scale when patterns and similarities started emerging from archeological studies. Patterns such as the discovery of fossils that were formed within the same period.
Explanation:
Geologists who study matter that make up the Earth's crust (whether solid gaseous or liquid), as well as matter from other terrestrial planets and the processes that influence the formation and condition of this matter, are called geologists.
They have successfully calibrated history into various phases of time intervals. These intervals are event-based intervals. For example, you have Eons, Eras, and Periods.
An Eon is a billion years. An example is the Neoproterozoid Eon. Eons are made up of several Eras and Eras are made up of periods. An example of an era is the Mesozoic era. Whilst periods are smaller units of an era, eg. Triassic era.
As scientists deduced the causes for the formation of fossils and topographical remains/patterns, they collected events that occurred within the same time period and group them together.
This range of events became known as the geological time scale.
The age of fossils and rocks is also used to map out the calibrations on the scale.
The age of fossils and rocks is determined using the process of radioactive dating.

what is a tumor and what does it have to do with mitosis
ASAP
will give brainliest
Answer:
Tumors constantly undergo mitosis.
Explanation:
Tumors are (generally) considered to be cancerous; therefore, they divide uncontrollably. Tumors undergo mitosis just like any other cell in your body but can be dangerous over time if not dealt with.
Answer:
What is cancer and what does it have to do with mitosis?
Cancer: mitosis out of control
Mitosis is closely controlled by the genes inside every cell. Sometimes this control can go wrong. If that happens in just a single cell, it can replicate itself to make new cells that are also out of control. These are cancer cells.

The farmer realizes he could sell mini-dragons as pets, but doesn't want them to breathe fire, because that would be dangerous. Suggest two parental genotypes for parents that would produce mini, non-fire breathing dragons.
Answer:
ddff and DDFf
Explanation:
From the information given:
Let DD represents the dwarf traits and FF represents the ability for the dragons to breathe fire.
Also, if dd represents the normal traits and ff represents the inability of the dragons to breathe fire.
Then; we can cross a dominant trait for dwarfism which has a heterozygous trait for fire with a recessive trait of normal and nonfire.
The two parental gametes are: ddff and DDFf
Using a Punnet Square:
DF Df
df DdFf Ddff
df DdFf Ddff
From above; we could observe that the proportion of progenitors that will be dwarf and at the same time unable to breathe fire is 50%.
