Propuso la teoría catastrofista, según la cual habían sucedido varios episodios de extinción, debidos a grandes cataclismos, seguidos siempre de nuevos periodos de creación
Answer:
Georges Cuvier.
Explanation:
Georges Cuvier (1769-1832) fue un zoólogo quien propuso que la evolución era el resultado de extinciones producidas por catástrofes a las cuales les sucedían nuevas creaciones con distintas especies. Los ecosistemas con las catástrofes eran destrozados y en los suelos de estos quedaban los restos de los animales extintos formando parte de los estratos de la tierra.

Some protozoans have special organelles called contractile vacuoles that continually eliminate excess water from the cell. The presence of these organelles tells you that the environment Group of answer choices is hypotonic to the protozoan. contains a higher concentration of solutes than the protozoan. is isotonic to the protozoan. is hypertonic to the protozoan.
Answer:
is hypertonic to the protozoan.
Explanation:
The presence of contractile vacuoles tells us that the environment is hypertonic to the protozoan that contains a higher concentration of solutes in the outside environment than the protozoan. The water moves outside the cell if its concentration is higher inside the cell so due to diffusion and no need of extra water, the water removes by the contractile vacuole to the outside environment so we can say that the environment is is hypertonic to the protozoan.
In the electron transport chain, which structure forms a channel in the inner membrane of the mitochondria and adds phosphate to ADP
Answer: ATP synthase
Explanation:
The ATP synthase complex is an enzyme located in the inner membrane of the mitochondrion that catalyzes the synthesis of ATP from ADP, a phosphate group and energy supplied by a proton (H+) flux. This ATP synthesis occurs during cellular respiration, which is a set of biochemical reactions by which certain organic compounds are completely degraded by oxidation to inorganic substances. This process provides usable energy to the cell in the form of ATP.
During cellular respiration, ATP synthesis is termed oxidative phosphorylation and the proton flux takes place between the intermembrane space and the mitochondrial matrix. ATP synthase produces ATP when protons flow through it. The proton flow creates a pH gradient and an electrochemical gradient. This proton gradient is used by ATP synthase to form ATP via oxidative phosphorylation. ATP synthase acts as an ion channel that "returns" protons to the mitochondrial matrix. During this return, the Gibbs free energy produced during the generation of the oxidized forms of electron transporters is released. This energy is utilized for ATP synthesis. It must then be considered that the electron transport chain and oxidative phosphorylation are coupled by the proton gradient.
Which of the following is NOT true of
autotrophic protists?
A. these organisms can start food chains as producers
B. examples are like phytoplankton, dinoflagellates, and euglena
C. they feed off of other organisms
Answer:
C. they feed off of other organisms
Explanation:
Autographs, as the word auto suggests (auto : self) , produce their own food. So they wont feed on other organisms for their survival.
Therefore, option C is incorrect and since we have to find the incorrect option that is the answer.
Answer: C. they feed off of other organisms
Explanation:
describes the study of microbes in their natural habitats and the relationships between the microbes and that habitat.
Answer:
The study of microbes in their natural habitat and their relationship with each other and their environment is termed as Microbial ecology. It mainly constitutes of Viruses, Eukaryotes ,Bacteria and Archaea as its living entities.
Being omnipresent in the biosphere they impact the other life-forms up to a significant extent.
They also help maintaining biogeochemical cycle by nitrogen fixation, sulfur metabolism and methane metabolism. Microbes also play a vital role of availing energy in the ecosystems where sunlight is scarce and hence photosynthesis is not good means of energy trapping, in such ecosystems the microbes actively engage in fundamental ecological processes including production, decomposition, and fixation inside the host organism.
how to identify oxygen and carbon dioxide?
Answer:
Place a glowing splint in the test tube, and if it reignites, it could be oxygen. Place a burning splint into a test tube, and if it goes out, it could be carbon dioxide. Or, place carbon dioxide gas in limewater, and if it turns milky and gets chunks, it is carbon dioxide.
Answer: Place a glowing splint in the test tube, and if it reignites, it could be oxygen. Place a burning splint into a test tube, and if it goes out, it could be carbon dioxide. Or, place carbon dioxide gas in limewater, and if it turns milky and gets chunks, it is carbon dioxide.

Cattle ranchers would rely on which forecast to best care for their livestock?
Wet Bulb Globe Temperature Forecast
Heat Stress Forecast
Heat Index Forecast
Precipitation Forecast
Answer:
Heat Index Forecast
Explanation:
Weather forecasts help the farmers to lower plant productive and pests. Applying disease control and controlling the crops pest and unwanted guests. The heat index forecast is an index that combines the use of temperatures and humidity. It is condition that is expressed in outdoor activity. Livestock ranchers have to find places to keep their cattle can freely graze hence forecast method is important for taking care of their livestock.Answer: heat stress forecast
Explanation:
First of all go vegetarian, don’t eat precious cows. Second of all it’s heat stress forecast that’s what comes up when you search it ( meat industry- ew)

After ATP donates a phosphate group to a coupled reaction, then it becomes ADP. The ADP Group of answer choices can be recharged in an equilibrium reaction to form ATP. can be recharged in an oxidation reaction to form ATP. can be recharged with the release of energy to form ATP. is a waste product that will be broken down. can be recharged with the uptake of energy to form ATP.
Answer:
can be recharged with the uptake of energy to form ATP
Explanation:
The correct answer would be that the ADP can be recharged with the uptake of energy to form ATP.
ADP is converted to ATP within a cell when free energy is available. The free energy is stored by coupling a phosphate group to ADP to form ATP, such that:
ADP + P (inorganic) + Free Energy ------> ATP
Hence, ADP can only be recharged with the uptake of energy to form ATP, a kind of reaction generally referred to as endergonic reaction.

The scientific method is the process that scientists use to find out new information. It involves a question, a hypothesis, a prediction, collecting data, and analyzing that data to make a conclusion. How would you use the scientific method to answer this question: Do mice live longer when they are fed high-sugar diets? (15 points)
Answer:
Science deals with emperical to finding solutions to problem

This research should be subject to case study. You will select two groups of mice. One group with high feed of sugar diet and second group with a minimum diet of sugar. You will study the two groups in order to know which one lives longer
All of the given answer options represent organisms that could coexist in an ocean
ecosystem. In this hypothetical ecosystem, which organism will receive the least amount of
energy in the food pyramid?
Tuna
Great white shark
Seal
Anchovy
Answer:
B. Great white shark
Explanation:
In any food pyramid, the organism at the top of the food pyramid usually gets the least amount of energy in the food pyramid, while those at the bottom have the highest energy in the food pyramid. This is because, as energy moves up the pyramid, some are lost.
In an hypothetical ecosystem, the great white shark will top the food pyramid. Therefore, it would get the least amount of energy in the food pyramid.
