Proteins are the building blocks of tissues responsible for building and growth. Proteins are also an important nutrient that supplies different body processes. These are compounds that are composed of chains of amino acids that are crucial in DNA-coding during the processes of cell division. They are considered as the building blocks of life and are in every cell of organisms. Humans depend on protein from food sources, mostly meat and poultry, which are responsible for repair and energy in muscles.

Water, air pollution

Human activities: such as overfishing, rechanneling of the water for purposes such as irrigation, domestic or industrial use, or dredging of the bottom of the lake.

Explanation:

An ecosystem is composed of biotic and abiotic factors. Abiotic factors are non-living environmental factors such as water, air, soil, sunlight, and minerals. In aquatic ecosystems, abiotic factors include substrate type, water depth, nutrient levels, temperature, salinity, and waterflow. Biotic factors are the living organisms in the ecosystem and they include animals, birds, plants, fungi, etc.

In the image of the freshwater lake ecosystem given,

Biotic factors include: Fish (phytoplankton-eater, zooplankton-eater, predator)

, Crayfish

, Zooplankton

, Grasses, phytoplankton, herbivorous insect, worms.

Abiotic factors include: Sunlight, Rainfall, Sedimentation, Weather, Minerals, Temperature.

Changes that would impact the biotic factors include:

Pollution: pollution such as water pollution and air pollution will adversely impact the biotic factors.

Human activities: such as overfishing, rechanneling of the water for purposes such as irrigation, domestic or industrial use, or dredging of the bottom of the lake.

Which of the following processes occurs in eukaryotic gene expression?RNA polymerase requires tRNA to elongate the molecule.mRNA
nignag [31]

Answer:

A cap is added to the 5 end of the mRNA

Explanation:

In prokaryotes, the translation process takes place simultaneously with the transcription but the mRNA molecule after synthesis undergoes some post-translation modification which protects the mRNA from the cytosolic environment.

One of these modifications is known as capping which refers to the addition of the cap at 5' end of the mRNA. This cap is added by an enzyme called guanyl transferease and protects the end of the mRNA.

Thus, the selected option is correct.
