Which one of the following interspecies relationships has a negative effect on the abundance of both species?A. Commensalism
B. Parasitism
C. Predation
D. Competition
(I know that B is wrong)

Answers

Answer 1

Answer: D. Competition. Competition is a negative type of interaction among organism of the same (intraspecific) and different (interspecific) species. Organisms often compete when there is less resources in the environment. Because other organisms may be consuming or defending a resource, other organisms that need it need to compete, thus reducing the growth and survival of both competing organisms.

c. photosynthesis and respiration.
d. aerobic and anaerobic respiration.

Answers

The two main processes by which plant cells absorb, release, and useenergy are photosynthesis and respiration. The answer is letter C. Theprocess of photosynthesis is present in the chloroplasts of a pant cell.Photosynthesis uses the sun’s rays in the form of electromagnetic energy toconvert it into chemical energy to be used for the plants. It needs proteinsthat are present in the plants to perform a series of necessary conversions. Moreover,the energy from the sun is the main catalyst to convert the carbohydrates inthe plant into simpler sugars. And then a series of complex reaction takesplace that their end product is oxygen. The oxygen produced is the cellularrespiration.

Answer: C. photosynthesis and respiration.

Explanation:

Suppose that while the reverse osmosis system is running tank B becomes contaminated with salt water such that it ends up with a higher salt concentration than tank A. What would happen if the reverse osmosis system was turned off?A) There would be a net flow of water from tank A to tank B.B) There would be a net flow of water from tank B to tank A.C) Water would flow in equal amounts in both directions.

Answers

Answer:

The correct answer is: A) There would be a net flow of water from tank A to tank B.

Explanation:

Osmosis can be defined as the process by which molecules of a substance (water) tend to move from a region where its concentration is high to a region where is concentration is low across a semi-permeable membrane.
The force which causes this movement is called the Osmotic Pressure.
Reverse Osmosis can be defined as the process by which molecules of a substance (water) move from a region where its concentration is low to a region where its concentration is high, due to the application of a hydrostatic pressure which is more than the osmotic pressure.
In the given example, water is is being separated from the salt dissolved in it by the process of Reverse Osmosis.
This results in the accumulation of salt in Tank B and accumulation of pure water in Tank A. Reverse osmosis promotes the movement of water from Tank B (where the water concentration is low but salt concentration is high) to Tank A (where the water concentration is high but salt concentration is low) due to the hydrostatic pressure.
Stopping Reverse Osmosis will cause normal Osmosis to occur.
Hence, the water will move from tank A (where its concentration is high) to tank B (where its concentration is low) until water concentration in both the tanks become equal.

Where has the population reached the carrying capacity in the Graph shown above? (need help quick!)A. point C
B. point B
C. point A
D. point D

Answers

Answer:

The correct answer is option D. point D.

Explanation:

Carrying capacity is characterized as the maximum populace size that a domain can continue inconclusively. For most species, there are four factors that factor into figuring the carrying capacity of an individual population: food accessibility, water resources, habitat, and ecological conditions.

In a graph representation of population size in a time period increases until it reaches carrying capacity, carrying capacity is representing in the graph where the increase in curve becomes stable and makes a plateau.

Thus, the correct answer is option D. point D.

An organism has the following characteristics: cell wall, heterotrophic, unicellular, and prokaryote. What kingdom does it belong in?

Answers

Answer:

Bacteria

Explanation:

Bacteria are unicellular microorganisms, in other words, they have a single cell, with the genetic material spread by the cytoplasm.

In addition, bacteria have no nuclear envelope or specialized organelles, these are characteristics of prokaryotes.

There are autotrophic bacteria, capable of synthesizing their own food, while heterotrophic bacteria (parasitic bacteria) get food from living things, causing disease to them.

In addition, bacteria have a protection on the outside of the plasma membrane called cell wall (usually composed of amino acid-bound sugars).

Note: Bacteria were formerly part of the monera kingdom, however, the term "monera" is not currently used (except for some books) and the kingdom has been divided into Bacteria and Archaea.

How many total hydrogen (H) atoms are present in the reactants side of the equation C2H5OH+3O2→2CO2+3H2O?

Answers

there are 6 hydrogens on the reactants side

Final answer:

The reactant side of the given chemical equation C2H5OH + 3O2 → 2CO2 + 3H2O contains six hydrogen atoms.

Explanation:

The chemical equation in question is C2H5OH + 3O2 → 2CO2 + 3H2O. This refers to the reaction of ethanol (C2H5OH) with oxygen (O2), producing carbon dioxide (CO2) and water (H2O). From the chemical equation, the reactants side contains one ethanol molecule containing six hydrogen atoms. Hence, in terms of reactants, the number of hydrogen atoms involved in the equation is 6.
