Answer:

The correct answer will be:

1. Mutualism

2. Competition

3. Commensalism

Explanation:

In an ecosystem the organism interacts with each other in one of the following ways:

1. <u>Competition</u>- interaction occurs when two or more than two species depend on the same resources, sharing the same habitat and niche. These species will fight for the resources and both will be negatively affected.

2. <u>Commensalism-</u> interaction takes place when one organism is benefited while the other is neither harmed nor gained. For example- the interaction between Remora fish and large fish in the ocean.

3. <u>Mutualism</u> -occurs when the species are dependent on each other for the resources and both benefits each other. For example- the plants and birds co-evolved benefiting each other like animals helps in pollination and plants provide nectar to them.

Thus, the selected options are the correct answer.

White a paragraph comparing the organices in a to the organs in your body.
Vlada [557]

Answer:

An organ is a part of the body of a living organism perform a specific role in the body such as the stomach, the liver and many more. Organelles on other hand are like organs of the cells that are contained in the cytoplasm of cell these also have a certain specialized roles to play for the cell, and they all depend on each other. The example of the organelles are nucleus, mitochondria and many more.

* Organelles are structures inside the cytoplasm of cells

* Organs are amde up of tissues composed of group of specialized cells that, has a particular role in the body

A transcriptional repressor that controls the transcription of gene A is not normally active unless bound by an effector molecul
iren [92.7K]

Answer:

Increase in transcription

Explanation:

Transcription is the process of forming RNA from DNA. It can be controlled by many factors like a repressor. Repressor can bind to the operator region of the promoter and hinder the movement of RNA Polymerase enzyme, halting the process.

Here, it is given that the repressor needs to first bind to an effector molecule X. Once it binds to X, it is activated and then it can bind to operator of gene A to inhibit its transcription. If the X binding domain on repressor is mutated it wont be able to bind to X. Thus it wont get activated and wont be able to attach to operator region to inhibit transcription. Hence, transcription process will keep going on uncontrolled.

A metal body of mass 81 g occupies a volume of 30 cm3. Identify the metal.
Cerrena [4.2K]

Answer:

Aluminum

Explanation:

The density of Aluminum is 2.7 g/cm3

We know the volume and mass of the unknown metal, as density is mass/volume:  81g/30cm3 = 2.7 g/cm3 which is the density of Aluminum :)

Shell-builders use calcium carbonate molecules (CaCO3) to build their shells. Which of the choices above could be a source for t
Fudgin [204]

Answer:

The question is incomplete, the correct question is;

Shell-builders use calcium carbonate molecules (CaCO3) to build their shells. Which of the following choices could be a source for the carbon atoms in the calcium carbonate (CaCO3) molecules?

respiration by organisms such as plants, animals and microbes

burning coal

calcium ions

car exhaust

wildfires

Answer is all of the above options except calcium ions.

The source for the carbon atoms in the calcium carbonate (CaCO3) molecules include respiration by organisms such as plants, animals and microbes , burning coal , car exhaust  and wildfires.

Explanation:

Shell-builders (coral, oysters, lobsters, sea urchins, phytoplankton) utilize calcium carbonate molecules (CaCO3) to build their shells. The respiration process by organisms such as plants, animals and microbes, burning of fossil fuels, vehicle exhaust, wild fire etc produces carbon dioxide (CO2) and release it into the atmosphere. Oceans absorb carbon dioxide in the air by diffusing and dissolving it into the surface water. The amount of CO2 that dissolved in the water depends on concentrations of CO2, temperature of the water, wind, etc.

Phytoplanktons (microscopic, one-celled organisms) also bring carbon into the ocean from the air through photosynthesis, where they convert the carbon dioxide and water into glucose and other carbon compounds. These carbon compounds are consumed by the marine organisms and some carbon eventually ends up in deep seafloor sediments. The other processes which involved in the transfer of carbon from the air into deep seafloor sediments include photosynthesis , decomposition , waste products, etc.

The CO2 dissolved in the ocean combines with water molecules to produce carbonate (CO3-) ions, which then combine with calcium ions in the seawater to form calcium carbonate (CaCO3). This calcium carbonate is used by shell building organisms to build their shells, plates, inner skeletons etc.
