The organisms that harness non-biological energy and convert it to biologically relevant/useful energy are called __ 1 __ _. The organisms that consume these are called __ 2 __ _ (it should end in -ores) which occur at the ___ 3 ___ trophic level. The number of trophic levels that any ecological system will primarily dependent on the __4__ organisms.

Answers

Answer:

The organisms that harness non-biological energy and convert it to biologically relevant/useful energy are called __autotrophos or producers_. The organisms that consume these are called _herbivores_ (it should end in -ores) which occur at the __second_ trophic level. The number of trophic levels that any ecological system will primarily dependent on the _consumer_ organisms.

Explanation:

 In the trophic web occurs energy transference through organisms occupying different levels in the chain. Each level feeds on the preceding one and becomes food for the next one. The first link is occupied by autotroph organisms, which are the producer. The following links are the consumers: herbivores are primary consumers and feed on producers. Carnivores are secondary consumers and feed on herbivores, and so on. The last links are the decomposers, microorganisms that act on dead animals degrading organic matter.  

Every link has an effect on the superior links and the immediately anterior link, meaning that whenever one of the links changes, the other ones will be affected.  

Autotrophs or producers synthesize inorganic substances, such as light, and turn them into organic matter according to their own needs. These organisms are photoautotrophs, such as plants, or chemoautotrophs. They occur at the first trophic level.

Heterotrophs are those incapable of producing their own organic matter, so they feed on producers, depending on them to get proteins and energy. In the trophic chain, heterotrophic organisms occupy the first, second, or third consumer level, after producers. These animals can be herbivorous, carnivorous,  omnivorous, hematophagous, ichthyophagous, and etcetera. All of them depend on autotrophic organisms.

In the particular case of herbivores, they occur at the second throphic level feeding on producers and being eaten by carnivores.

In general, most trophic chains are composed of 4 or 5 levels, depending on the number of consumers present, and the energy transference between levels.

Amoeba sisters video recap Biomagnification

Answers

I suggest you watch the Amoeba Sisters video again, 1-2x and take notes.

Biomagnification is when toxins / heavy metal are present in small amounts in fish, but accumulate as you move into higher trophic levels. This is one reason why it can be toxic for humans to eat tertiary or quaternary consumers, such as swordfish, shark, etc.

Biomagnification refers to the presence of higher concentration of chemical toxins as a result of the accumulation of toxins in organisms.

What is biomagnigication?

Biomagnification is best explained as a condition in which the chemical concentration of a toxin is amplified in an organism compared to the environment in which the organism is found.

Biomagnification usually is observed as one goes higher in the trophic levels of organisms.

For example, chemical pollutant found in water may be present at tolerable levels. However, in organisms, living in the water, the concentration of the pollutant is higher as these organisms accumulate these toxins in their tissues.

Therefore, biomagnification refers to the accumulation of toxins in organisms higher than found in their environment.

What is photosynthesis???? ​

Answers

Explanation:

The process of green plants make their own food by present sunlight is called photo synthesis

I don't need follow or thanks but please subscribe to my mom channel

Hey there!

Photosynthesis is the reaction that converts light energy to chemical energy in sugar and carbohydrates. Humans can't eat sunlight, so we eat plants. Plants convert the energy in the sunlight into chemical energy using chlorophyll. Chlorophyll is a molecule produced by plants, algae, and cyanobacteria, which aids in the conversion of light energy into chemical bonds. It is the green pigment found in the chloroplasts of higher plants. They are a part of our ecosystem, and they are lower on the food chain.

scientists believe the earth likely warmed between 0.65 celsius and 1.05 celsius with an average value of 0.85 celsius between years 1880 and 2012. what was error bar for the increase in temperature over that period?

Answers

Answer:

The lower limit is 0.65°C

The upper limit is 1.05°C

the average is 0.85°C

The difference between the average and the lower limit is:

0.85°C - 0.65°C = 0.20°C

the difference between th average and the upper limit is:

0.85°C - 1.05°C = -0.20°C

Then we can write the change in temperature as:

T = 0.85°C ± 0.20°C

Now we want to find the error bar.

The error bar would be the total distance between the lowest value and the largest value.

Then the error bar is:

1.05°C - 0.65°C = 0.40°C

notice that the error bar is twice the error, which makes a lot of sense because the error (± 0.20°C) goes up and down.

Then the error bar in this measure has a magnitude of 0.40°C.

A suspension of yeast cells is being grown under anaerobic conditions such that glucose is metabolized to ethanol and carbon dioxide. An inhibitor of alcohol dehydrogenase is added to the suspension, the cells rapidly die. Explain.

Answers

Answer:

The correct answer is - NAD needed to keep glycolysis going is not being recycled so the entire process is shut down and no ATP is produced

Explanation:

Alcohol dehydrogenase plays role in metabolizing the bulk of ethanol consumed as part of the diet and their activities contribute to the rate of ethanol elimination from the body.

Inhibitor of this zinc enzyme prevents it to perform its function which results in NADH generated during anaerobic conditions glycolysis cannot be recycled back to NAD+, So the ATP production pf anaerobic condition through glycolysis cannot be maintained.

Question 19
How would the carbon cycle be influenced by an increase in aerobic respiration?

Answers

Answer:

Cellular respiration does not affect the carbon cycle but is part of the carbon cycle. The 2 carbon cycles. carbon ( C ) is taken up by the plants and trees in the form of carbon dioxide ( CO2 ). Plants converts this CO2 into organic compounds such as glucose ( C6H12O6 ).

Explanation:

Increase in aerobic respiration will lead to increase in the amount of CO2 released into to the atmosphere due to respiration.

Aerobic respiration occurs when oxygen is combined with glucose to yield carbon dioxide and water. This is one of the major ways through which carbon dioxide enters the carbon cycle.

Note that the carbon cycle shows the movement of carbon in nature. Increase in aerobic respiration means that more carbon will be introduced into the atmosphere as carbon dioxide.

The nitrogen cycle is the using and reusing of nitrogen in an ecosystem. True or false?

Answers

Answer:

True

Explanation:

Nitrogen is a fundamental component of both inorganic and organic compounds, where it is the main constituent of biomolecules such as nucleic acids (DNA, RNA) and proteins. The nitrogen cycle refers to the biogeochemical processes by which nitrogen circulates between the components of an ecosystem, i.e., between organisms (like plants and decomposers), and non-living things (i.e., soil, water, air). This cycle consists of several processes which include, among others, nitrogen fixation (i.e., the process by which nitrogen in the atmosphere is converted into ammonia), nitrification (i.e., the oxidation of ammonia is oxidized into nitrite and subsequent transformation of nitrites into nitrates), denitrification (where nitrate is reduced), anaerobic ammonia oxidation and putrefaction.

Glycogen is an important and quickly mobilized source of stored glucose. Glucose is mobilized for ATP generation in muscle in response to epinephrine, which activates Gs. How would inhibitors of cAMP phosphodiesterase affect glucose mobilization in muscle

Answers

Answer:

Glucose mobilization would continue

Explanation:

The GTP-bound alpha subunit (Gαs) is a subunit of the heterotrimeric G protein which is required for stimulating the cAMP-dependent pathway through the activation of the membrane-associated enzyme adenylyl cyclase, which in turn catalyzes the synthesis of the second messenger cyclic-3′,5′-adenosine monophosphate (cAMP) from ATP. Moreover, cAMP phosphodiesterase is an enzyme that hydrolyzes cAMP, thereby negatively regulating the levels of this second messenger, which is fundamental for the termination of the signal. In this case, the epinephrine signal initiates glycogen breakdown (glucose mobilization) in muscle cells. In consequence, if the cAMP phosphodiesterase enzyme is inhibited, the concentration of cAMP will persist high even beyond the termination of the signal, thereby glucose mobilization would continue.

1. Describe the purpose of mitosis.
2. Describe what is happening in each stage and what each stage looks like:
Prophase
Prometaphase
Metaphase
Anaphase
Telophase
Cytokinesis

Answers

Answer:

1) The purpose of mitosis is growth and repair of cells

Explanation:

Prophase:

-DNA condenses (supercoiled, chromatids are visible under light microscope);

-Nuclear membrane begins to disintegrate (by the end of prophase  it is completely gone)

-Centrioles move to opposite ends of the cell

-Splinde fibers start to form from the centrioles and grow

Metaphase:

-Spindle fibers, departing from both poles, are attached to each centromere, on opposite sides

-The spindle fibers pull the chromosomes back and forth until they align in a plane along the equator of the cell, which is called the equatorial plane

Anaphase:

-The spindle fibers shorten

-The centromeres of sister chromatids split

-Chromatids move apart, pulled by the spindle fibers

-Chromatids become chromosomes

-Half of the chromosomes move to one cell pole, half to the other

Telophase:

-The chromosomes reach the cell pole

-Nuclear membrane reforms

-Spindle fibers break down and disappear

-The chromosomes begin to uncoil, which makes them diffuse and less compact

Cytokinesis:

-The cell membrane pinches inward until the cell divides in two;

-There are two daughter cells with the same structures and number of chromosomes as the parent cell

-Chromosomes decondense
