An example of a severe disruption to an ecosystem is (1 po O repurposing a building in a downtown area O a thunderstorm that knocks down some trees o the loss of a river system due to contamination O seasonal flooding of a river
Answers
Answer:
C
Explanation:
All of these pose major danger and disruption, but most can be fixed or don't pose long-term effects. Destroying an entire water source can cause drought or death of water-dwelling species, which can affect the other parts of the ecosystem and maybe even eliminate the whole ecosystem, if not dealt with soon enough.

(A) True or (B) False: Two species of lizard with the same thermal niche could coexist in the same range.
Answers
Explaining: False
The statement "two species of lizard with the same thermal niche could coexist in the same range" is true.
What is species?Species is the term that is used to classify different organisms. Species is the second last classification, which means most similar organisms are present in this classification. The traits are mostly similar in these organisms.
Two species of lizards are given the same thermal niche. So these lizards have similar characteristics of thermal niches. So these lizards can live in the same range because they can coexist. But in these organisms, there can be competition between them.
The statement can be true as it can coexist in the same range as they have a similar thermal niche. They can live in the same temperature.
Therefore, the statement is false.

How do flowers attract pollinators
Answers
Answer:
Explanation:
Plants produce nectar to attract pollinators. As the pollinator moves from flower to flower collecting nectar, they are also moving pollen from flower to flower. Certain fruits and seeds will not be produced if their flowers are not pollinated.
Flowering plants need to get pollenDust-like grains that contain male sex cells (gametes) of flowering plants (angiosperms) and cone plants (gymnosperms). Pollen is made on the anthers of flowering plants. from one flower to another, either within a plant for self-pollination or between plants of the same species for cross-pollination to occur. However, pollen can’t move on its own, so animals or the wind (and water in rare cases) move the pollen for plants.

How does carbon dioxide concentration affect photosynthesis rate?
Answers
Answer:
An increase in the carbon dioxide concentration increases the rate at which carbon is incorporated into carbohydrate in the light-independent reaction - and so the rate of photosynthesis generally increases until limited by another factor.
Explanation:
CO2 concentration is directly proportional to rate of photosynthesis.
CO2 is raw material for process of photosynthesis.
CO2 + H2O → C6H12O6 + O2
Increase in CO2 concentration increases rate of photosynthesis.
Decrease in CO2 concentration decreases rate of photosynthesis.
Therefore, CO2 concentration is limiting factor for rate of photosynthesis.
What observations and evidence support the theory of evolution?.
Answers
Answer:
direct observation, the existence of homologies and fossils, and certain biogeographical patterns.
Explanation:
These provide solid evidence that organisms from the past are not the same as those found today, and fossils show a progression of evolution. Scientists determine the age of fossils and categorize them from all over the world to determine when the organisms lived relative to each other. The resulting fossil record tells the story of the past and shows the evolution of form over millions of years.
Molecular Biology:
Like anatomical structures, the structures of the molecules of life reflect descent with modification. Evidence of a common ancestor for all of life is reflected in the universality of DNA as the genetic material and in the near universality of the genetic code and the machinery of DNA replication and expression. Fundamental divisions in life between the three domains are reflected in major structural differences in otherwise conservative structures such as the components of ribosomes and the structures of membranes. In general, the relatedness of groups of organisms is reflected in the similarity of their DNA sequences—exactly the pattern that would be expected from descent and diversification from a common ancestor.

Explanation:
PLZ give a crown
Answer:
plants are called photosynthetic autotrophs...
WHY ARE THEY CALLED PHOTOSYNTHETIC...?!? because they convert light energy (i.e. sunlight) to chemical energy (i.e. glucose) this process is called photosynthesis. The Photosynthetic formula is 6CO2 + 6H2O ---> GLUCOSE + 6O2......
WHY ARE THEY CALLED AUTOTROPHS....?!? because they make their own food by using inorganic sources that is Water and Carbon dioxide. they are fully independant from other organism. So they do not feed on any other organism for survival hence they are found on the bottom of the energy pyramid so if they wouldn't convert light energy into chemical energy all the animals would be dead because we are not autotrophs we can not make our own food by using inorganic sources we need already made organic food thats why those organisms which can not make their own food are called heterotrophs

Answers
Glycogen storage after physical activity will be accelerated by taking a high carbohydrate snack within two hours of exercise.
What is Glycogen?Glycogen is a polysaccharide that forms glucose after hydrolysis has taken place.
They exists as substance which are deposited in bodily tissues and serve as a store of carbohydrates.
When one consumes a high carbohydrate snack within 2 hours of exercise, muscle tissue which are spongelike will rapidly soak up glucose from the high-glycemic carbohydrates.

B. Oxygen molecules are broken down and converted into pyruvic acid.
C. High-energy electrons and hydrogen ions are passed to NAD+ forming NADH.
D. Carbon atoms in glucose are transferred to ADP, forming ATP.
Answers
Answer:
C. High-energy electrons and hydrogen ions are passed to NAD+ forming NADH.
Explanation:
The sixth step in glycolysis is the first of the two-energy-conserving reactions of glycolysis which results in the formation of ATP. This step involves the oxidation of glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate.
In the oxidation of glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate, high-energy electrons and hydrogen ions are passed to NAD⁺ forming NADH.
Glyceraldehyde-3-phosphate + inorganic phosphate + NAD⁺ ----> 1,3-bisphosphoglycerate + NADH + H⁺
The NADH produced in this reaction transports the high-energy electrons passed to it through the electron transport chain to produce ATP in oxidative phosphorylation.

Only animals being modified genetically is not true of GMOs. Genetically
modified organisms(GMOs) usually undergo some changes to their DNA in

The infused trait through DNA alteration helps to increase the quality and
yield of crops thereby making them readily available for the population.
Plants and animals undergo this process and isn't restricted to animals
