Ecosystem is that it is a community or group of living organisms that live in and interact with each other in a specific environment.

For instance, tropical forests are ecosystems made up of living beings such as trees, plants, animals, insects and micro-organisms that are in constant interaction between themselves and that are affected by other physical (sun, temperature) or chemical (oxygen or nutrients) components.

An ecosystem consists of a community of organisms together with their physical environment.
Ecosystems can be of different sizes and can be marine, aquatic, or terrestrial. Broad categories of terrestrial ecosystems are called biomes.
In ecosystems, both matter and energy are conserved. Energy flows through the system—usually from light to heat—while matter is recycled.
Ecosystems with higher biodiversity tend to be more stable with greater resistance and resilience in the face of disturbances, or disruptive events.

Question 5

pantera1 [17]

Answer:

The solubility of a gas in a liquid occurs faster if the liquid is cooled. Hence the correct answer is option B.

Explanation:

The solubility of a gas in a liquid occurs faster than a solid. Solid solute takes much time to be dissolved in a solvent. This is because of the bonding. The bond of the solid is is much stronger when compared to the gaseous state. This is one of the reasons of gaseous dissolving faster than solid.

A gaseous state is defined as a material whose atoms are not closely attached with one another and is free to move in any direction. And when we have to mix gas in a liquid in a faster rate the liquid temperature should be lowered.

Answer:

D Independent assortment occurs when chromosomes separate during meiosis and causes variations that can be beneficial or harmful to a species

Explanation:

During meiosis, the homologous chromosomes separate and segregate independently of each other. This process is referred to as 'independent assortment'. In consequence, different gene variants or 'alleles' localized in homologous chromosomes segregate independently of each other during gamete formation, thereby one particular gamete has an equal probability to carry either of these segregating alleles. Independent assortment generates genetic variation in the gametes, which can be beneficial or deleterious in a given environment.

fenix001 [56]

Answer:

A = Activator

B = Effector

Explanation:

An activator is a protein which typically binds to a short (50–1500 bp) region of DNA which might be located either upstream (mainly) or downstream of a gene so as to cause increased transcription. This particular region of DNA is known as enhancer and activator is also known as transcription factor. Activator is a trans-acting factor which binds to the cis-acting factor which is enhancer so as to enhance transcriptional expression.

But another protein named as effector may restrict activator from binding to the enhancer leading to a decrease in transcriptional expression by binding to the activator allosterically. Allosteric binding of effector to the activator causes conformational change in activator so it can no longer bind the enhancer.
