Light and Water both are among the ecological factors .
Ecological factors are those components of environment which determine the variation in the chemical and physical nature of different ecosystem.
A balanced ecosystem needs to have all its ecological factors in adequate amount.
Thus, too much water, too much light, not enough light or not enough water , any of these condition can upset the balance of ecosystem.

Which of the following is not an essential role of the liver? Which of the following is not an essential role of the liver? prot

True [87]

Answer: urea disposal

Explanation:

<u>The liver, which is the largest organ in the human body, performs three vital functions of the organism: detoxification, synthesis and storage. </u>

The liver acts as an authentic filter that collects and eliminates numerous toxins, such as ammonia, or toxins that we ingest, such as alcohol (it performs a biotransformation of toxins). Our liver is also responsible for the metabolism of carbohydrates, lipids and proteins, secreting bile, an essential element for the digestion. It also prevents bleeding through a coagulation process. And it is a container of vitamins (A, D, E, K) and glycogen (carbohydrates), while energy is stored in the form of sugar, made available to our organization.

The urea cycle takes place primarily in the liver. Organisms convert ammonia to a less toxic substance, such as urea, via the urea cycle. <u>Then it is released into the bloodstream where it travels to the kidneys and is ultimately excreted in urine. </u>

So, the liver is involved in the production of urea, but the kidney is responsible of its disposal.

Which of the following is not a way that sexual reproduction increases genetic diversity?

cricket20 [7]

Answer:

Combined parenting leads to faster reproduction

Explanation:

Genetic diversity or variations in the physical appearance of organisms is caused by genetic or environmental factors. Reproduction brings about variation through gamete formation, fertilization and mutations.

During prophase 1 of meiosis, homologous chromosomes pair to form bivalents. The crossing over at the chiasmata results in new gene combination and variations.

Fertilization permits parental genes to be brought together. This causes variations in members of the same family.

Mutation is the spontaneous change in genetic make-up. These changes may be inherited by offspring bringing variations. However, combining parenting does not increase genetic diversity.
