When 2 or more organisms compete for the same resource there can be a variety of outcomes. What would be one of those outcomes?

Answers

Answer:

The biology branch deals with the relations between and physical environment of organisms.

Explanation:

The principle of competitive exclusion states that if two species occupy the same niche, they cannot exist together (competing for identical resources). Two species whose niche overlap can evolve to have different niches through natural selection, resulting in the distribution of resources.

In ecology, interspecific competition is a form of competition where individuals from different kinds compete in an ecosystem for the same resources (e.g. food or space)... There may be interspecific competition if people of two separate species share a limited resource within a single area.

Explain the difference between exponential growth models and logistic growth models and insert a picture of each model.

Answers

Answer:

When the per capita rate of increase ( r) takes the same positive value regardless of the population size, then we get exponential growth. When the per capita rate of increase ( r) decreases as the population increases towards a maximum limit, then we get logistic growth.

Explanation:

Exponential population growth: When resources are unlimited, populations exhibit exponential growth, resulting in a J-shaped curve. When resources are limited, populations exhibit logistic growth. In logistic growth, population expansion decreases as resources become scarce.

When the stimulus voltage is increased, _______. When the stimulus voltage is increased, _______. sodium permeability into the cell decreases sodium permeability into the cell increases to overcome the potassium exiting a greater-than-threshold depolarization results a greater-than-threshold depolarization results and sodium permeability into the cell increases to overcome the potassium exiting.

Answers

Answer:

a greater-than-threshold depolarization results and sodium permeability into the cell increases to overcome the potassium exiting.

Explanation:

The occurrence of action potential requires the existence of active voltage-dependent channels to open and close in response to the membrane depolarization.  

When depolarization reaches and supers the threshold point, voltage-dependent Na+ channels open and the ion gets into the cell. The entrance of Na+ decreases the electric charge difference between the cellular interior and exterior. Membrane depolarizes and produces the action potential that tends to reach a potential equilibrium for Na+ = +60mV. The higher the Na+ input is, the greater is the depolarization and the greater is the Na+ permeability.

Once Na+ channels are closed, voltage-dependent K+ channels open, increasing the membrane permeability to the ion, letting K+ get out of the cell, following the electrochemical gradient.  

The closure of Na+ channels and opening of K+ channels are responsible for membrane repolarization.

A sequence of chemical processes known as cellular respiration convert glucose into ATP, which can then be used as energy for a variety of bodily functions.

What is cellular respiration?

Glycolysis, the citric acid cycle, and oxidative phosphorylation are the three basic processes that take place during cellular respiration. The citric acid cycle happens in the mitochondrial matrix, oxidative phosphorylation happens on the inner mitochondrial membrane, and glycolysis happens in the cytoplasm.

Glucose, ATP, and NAD+ are the initial reactants and ATP and H2O are the end products of cellular respiration. The enzymes phosphofructokinase-1, pyruvate dehydrogenase, and isocitrate dehydrogenase control the rate of cellular respiration.

Disorders that interfere with cellular respiration often impair one or more of the enzymes necessary for it, such as succinyl-CoA synthase or pyruvate kinase.

Therefore, A sequence of chemical processes known as cellular respiration convert glucose into ATP, which can then be used as energy for a variety of bodily functions.

What is the structure of a Triglyceride?
A. A glycerol head with 3 fatty acid tails
B. 3 Glycogen heads connected to a Hydroxyl tail
C. 3 Hydroxyls connected to a glyceride
D. A glycerol head with 2 fatty acid tails

Answers

Answer:

A. A glycerol head with 3 fatty acid tails

Explanation:

One glycerol attached to 3 fatty acids each

The structure of a Triglyceride is  a glycerol head with 3 fatty acid tails. Hence the correct option is A.

The structure of a triglyceride consists of a glycerol molecule bonded to three fatty acid tails. Glycerol is a three-carbon alcohol with a hydroxyl group attached to each carbon, while fatty acids are long hydrocarbon chains with a carboxyl group at one end. Through a condensation reaction, the hydroxyl group of each glycerol molecule combines with the carboxyl group of a fatty acid, resulting in the formation of an ester bond.

This process is repeated three times, with each fatty acid binding to a different carbon of the glycerol molecule, thus forming a triglyceride. The three fatty acid tails provide energy storage and insulation properties, while the glycerol molecule serves as a backbone for their attachment. Triglycerides are the main storage form of fat in animals and plants.

Hence the correct option is A.

In the early days of the solar system, many planetesimals orbited the Sun. The theory has it that one large planetesimal the size of Mars struck a glancing blow to the molten Earth. How did this event contribute to the formation of the Moon?

Answers

Answer:

This event led to the breaking away of a part of earth and the part was held on by earth’s gravity and this part became the moon.

Explanation:

The formation of moon was after the formation of the earth. In the initial years of the formation of earth it was affected by several asteroid hits and comets. Small planets referred to as planetesimals  also kept continuously affecting the earth. Before 4.5 billion years ago a planetesimal which was about the size of Mars hit earth.

This hit led to the breaking away of a part of earth. The part which was sent to space by the hit was caught by the gravity of the earth and the part started orbiting around the earth. The similarity of the rocks in moon to that of earth is attributed to the fact that moon was actually formed from earth.

The moon and earth keeps influencing each other. The moon’s effect reduced the speed of earth’s rotation and the moon keeps moving away from the earth due to the influence of earth.

Answer:Molten rock broke off from Earth following the impact. The rock coalesced (gathered) into a ball, which formed the Moon.

The carrying capacity for a population of frogs in a rainforest ecosystem is 840 frogs, and the maximum rate of increase for this population is 1.0 per individual per year. Using the logistic population growth model, what is the approximate population growth rate for 212 frogs?

4 frogs per year
29 frogs per year
158 frogs per year
314 frogs per year

Answers

Answer:

4 frogs per year is the answer

In logistic growth, a population's per capita growth rate gets smaller and smaller as population size approaches a maximum imposed by limited resources in the environment, known as the carrying capacity (K).

Formula used:  dN/dT= rN{1-N/K}

Given: k= 840 frogs

            N= 212, r= 1 year

To find: r=?

Solution:

putting value in equation:

                          dN/dT= rN{1-N/K}

                          dN/dT = 1 x 212 {1-212/840}

                   so,    dN/dT= 158.57 ( approx)

                   

Final answer: The correct option is (c)

158 frogs per year

Thus, we can conclude that 158 frogs per year will be the population of frogs.

ou have isolated a previously unstudied protein, identified its complete structure in detail, and determined that it catalyzes the breakdown of a large substrate. You notice it has two binding sites. One of these is large, apparently the bonding site for the large substrate; the other is small, possibly a binding site for a regulatory molecule. What do these findings tell you about the mechanism of this protein

Answers

Answer:

These findings tell us that possibly this protein has an enzymatic function, that is, it is an enzyme.

Its function can be catalytic as well as analytical.

The substrate binding site should be the largest, while the other regulatory site is the smallest.

Explanation:

This happens since hormones regulate their enzymatic activity through inhibitory sites.

They have another smaller binding site, where when an inhibitory molecule binds, it deforms the morphology of the protein causing it to no longer bind to its substrate at the binding site, therefore they inhibit the chemical reaction that is happening within the enzyme. both catalytic and analytical.
