Answer:
Fibrin
Explanation:
The name of the element that is critical for initiating the formation of a blood clot is fibrin.
Fibrin is a fibrous, non-globular protein that is formed by the polymerization of fibrinogen as a result of the reaction with protease thrombin. The threads from fibrin form a network of fibers around the platelet plug at the area of damaged blood vessels in the process of injuries, thereby forming the initial clot.

Explanation:
Excretion refers to the removal of waste products that is produced from amino acids metabolism.
Carbon dioxide is formed in living organisms in the process of both aerobic respiration and anaerobic respiration and can be removed from the body through lungs.
Urea is produced in the liver and then the blood is to be sent to the kidney and which is excreted from the body.
Urea is compounds of nitrogen which is formed from amino acids that contains toxic substances which the body does not need.

Many rain forest plants are prone to developing fungal infections on their leaves. Fungi can grow rapidly in moist environments, and a serious infection can kill plants
Answer:
Resistance plants increase in number whereas non-resistant plants decreases.
Explanation:
The environment of rain forest is suitable for the fungal growth because of the presence of humidity in the environment and we know that fungi needs moist places for its growth. These fungus attached on the leaves and takes nutrients from that plant that leads to the stunted growth and many cases death of the plant occurs. Some plants have no effect of this fungus due to the presence of resistance in them so if the fungus spreads in the whole forest so the plants which are prone to these fungal infections eliminated from that environment and resistant plants are increase in number.
Answer:
Part B
Many rain forest plants are prone to developing fungal infections on their leaves. Fungi can grow rapidly in moist environments, and a serious infection can kill plants. One rain forest plant species has a genetic variation that affects its leaf structure. The traits and the descriptions of the plant’s leaves are listed in the chart.

The cactus has a specialized fleshy stem that is specialized to store water for long periods of time. Which plant tissue most likely makes this action possible?
I know the answer is Ground, but i need to know WHY the answer is ground tissue. I WILL MARK BRAINLIEST
(on EDGE)
Answer:
If I were to guess its probably Vascular
Explanation:
Cactuses can store water nearly four months mainly in the winter and watering is not required for them frequently during that time. The stem acts as a reservoir for the amount of water it holds. The ground tissue of cactus has lots of parenchymal cells that store water.
What is parenchyma?The ground tissue system comes from a ground meristem which has three tissues, namely parenchyma, collenchyma, and sclerenchyma.
The ground tissue of cactus has many parenchyma cells that store water.
Thus, it can be concluded that the ground tissues helps cactus to store water for a long time.

Explanation:
have you pooped today?
The option which describes the function of RNA polymerase is that it forms an RNA strand using a DNA strand as a template. Thus, the correct option for this question is D.
What is RNA polymerase?RNA polymerase may be defined as a multi-unit enzyme that synthesizes RNA molecules from a template of DNA through a process called transcription. This enzyme is responsible for copying a DNA sequence into an RNA sequence, during the process of transcription.
RNA polymerase binds to DNA, separates the strands, then uses one of the strands as a template from which to assemble nucleotides into a complementary RNA strand.
It uses a single-stranded DNA template to synthesize a complementary strand of RNA. Specifically, RNA polymerase builds an RNA strand in the 5' to 3' direction, adding each new nucleotide to the 3' end of the strand.
Therefore, the option which describes the function of RNA polymerase is that it forms an RNA strand using a DNA strand as a template. Thus, the correct option for this question is D.
