Explain how the turtle’s evolutionary process evolved the function of turtles shells?
Answer:
The explanation for the turtle's evolutionary process was quite a challenging one for evolutionists.
Two categories of paradigms have come to offer their ideas about how they think the turtle came about its amour.
Palaeontologists (that is, those who examine and report on the history of life here on earth using fossil records) state that the turtle's shell developed into what it is now over time from bony scales same as those which can be found on armadilloes and crocodiles.
Development biologists have a very different opinion. They theorize that the shell evolved out of ribs. The ribs, according to them due to the need for environmental adaptation, became wider, and flatter and eventually merged to form shells.

Humans have the most urgent need for a continuous supply of ________. Group of answer choices d. water a. food b. nitrogen c. oxygen
Answer:
Option "C" Oxygen is the correct answer to the following question:
Explanation:
We know that, Just as a human absorbs oxygen into the body through inhalation, the oxygen enters into the whole body also in the blood and is used in the body by cells, so we can say that the human body needs a constant supply of oxygen. therefore, the appropriate option is true

Explanation:
Allison and Heather are going to conduct an experiment to see whether salt affects the growth of plants. They gather five groups of identical plants and give the plants in each group water with a different salt concentration. What is the outcome variable (dependent variable) for their experiment?
Answer:
The dependant variable is the growth of the plants.
Explanation:
The independent variable is what changes the dependent variable.
for example, the type of salt concentration ( Independent variable ) is/ isn't going to change the growth ( dependant variable ) of the plant.
The dependant variable is the growth of the plants.This is the outcome of the experiment in which salt affects the growth of plants.
What are plants?Plants are the eukaryotes means they are multicellular organisms and they belong to the kingdom Plantae. So, the scientific name of plants are Plantae and its domain is Eukaryota.
The plants are of many types such as shrubs, herbs, mosses, ferns, trees and they grow on a particular place by absorbing inorganic substances and water from the soil through the roots.
Plant are also known as autotrophs as they prepares there own food in the presence of sunlight. Due to chlorophyll present in them the plants shows green colour.
Plants are also known as producers because they produce food to feed others.
Therefore, the dependant variable is the growth of the plants.This is the outcome of the experiment in which salt affects the growth of plants.

What is the endosymbiotic hypothesis?
Answer: What does the endosymbiont hypothesis propose? It proposes that early eukaryotic cells acquired the precursors of mitochondria and chloroplasts by engulfing certain types of bacteria. ... Mitochondria, chloroplasts, and centrioles in eukaryotic cells each contain their own minute and unique supply of DNA.
Explanation:
The first piece of evidence that needed to be found to support the endosymbiotic hypothesis was whether or not mitochondria and chloroplasts have their own DNA and if this DNA is similar to bacterial DNA. This was later proven to be true for DNA, RNA, ribosomes, chlorophyll (for chloroplasts), and protein synthesis.
Why is a Mango tree more evolved than a Bacteria or a Mushroom.
Answer:
Mango tree is more complex and evolved because, it is eukaryotic, autotrophic, terrestrial and a sporophyte with covered seed. The bacteria is a unicellular prokaryote and fungi is heterotrophic, simple thallophyte with no tissue system.
If you pumped contaminated water from an aquifer, cleaned the water and pumped it back in what would happen?
Question 2 options:
The water would be re-contaminated by rock and soil in the aquifer
The water would clean the aquifer
It’s impossible to know what would happen
The water would be clean and stay clean
Answer:
It’s impossible to know what would happen
Explanation:
If contaminated water is pumped form an aquifer, cleaned and pumped back, it would be impossible to know what would happen unless the source of the contaminant is known.
If the source of the contaminant is known and removed before the water is pumped back into the acquifer, the water would be clean and stay clean provided that all the water was initially pumped off. If the source of the contaminant is not known, it would be difficult to predict what would happen.

b. scientific modeling
c. genetic engineering
d. genomics
Answer: b
Explanation:b
Answer: A
Explanation:
Modeling usually involves a simulation to make some kind of prediction or comparison. Genetic engineering involves changing the genetic makeup of an organism. Genomics is a new field dealing with gene mapping. The use of quinine for medicinal purposes is an early form of biotechnology. Four hundred years ago they were not mapping the genes of the cinchona tree.

Need help. ASAP What are considered characteristics of science? Select all that apply. - Scientific experiments are not falsifiable. - Scientific experiments are peer-reviewed. - Scientific conclusions are based on anecdotal evidence. - Scientific phenomena are observable. - Scientific hypotheses are testable.
Answer:
- Scientific experiments are not falsifiable.
- Scientific experiments are peer-reviewed.
- Scientific hypotheses are testable
Explanation:
The scientific method refers to the process of examination of scientific hypotheses. This method is rigorous and requires 1-to raise questions about an observed phenomenon, 2-to produce an experiment and 3-to confirm this hypothesis by analyzing the results. The last step of scientific research is the peer review process, where independent researchers (usually 2-3 researchers) review the observed evidence in order to confirm or reject the results obtained from the experimentation. This hypothesis must also be testable, ie, it is imperative that it can be confirmed in further experiments.

Being able to respond to change (irritability) is one of the necessary life functions. Which body system is mostly responsible for this function
Answer:
The correct answer is : nervous system.
Explanation:
Irritability is one of the key aspect life which is deal with being able to response or change according to the stimuli that is occur and disturbs the homeostasis of the body which is maintaining the body environment for living.
Nervous system is deal with the irritability by sensing the stimuli in which change occur it can be physical stimuli such as temperature, light, or sound or chemical stimuli such as pH, ions, amount of required chemical or biological stimuli such microbes in body. All these stimuli are sense b the sensory neurons and then send these signals to brain or spinal cord in order t act and respond accordingly to maintain homeostasis.
Thus, the correct answer is : nervous sytem.
