Answers

Plants have evolved to respond to critical changes in the environment by either growing their roots, or leaves towards/away from any stimulus. This response, is called a tropism.

For example, The plant's stem and leaves bend toward sunlight. Their roots grow toward Earth's gravity.

Plants have complicated systems to detect and then respond to changes in light, gravity, temperature, and or even physical touch.

enzymes that cleave nucleotides from the ends of a dna molecule are known as what?

Answers

Restriction enzymes. These enzymes are commonly found in bacteria and are able to cleave DNA at specific parts within DNA

Enzymes that cleave nucleotides from the ends of a DNA molecule are known as Restriction endonucleases.

What are Enzymes?

Enzymes may be defined as the type of biocatalysts that significantly increase the rate of a chemical reaction without being changed in the overall process. It is thought that all cellular reactions and processes are mediated by enzymes.

Restriction endonucleases are the enzymes that are also called molecular scissors which are responsible for cutting DNA at specific sites. These enzymes are present in bacteria in order to provide a defense mechanism called the restriction modification system.

There are various types of restriction enzymes are known. For example, BamH1, EcoRI, Hind III, etc.

Therefore, restriction endonucleases are the enzymes that cleave nucleotides from the ends of a DNA molecule.

i got the answers off a quiz let

At the most basic level, schizophrenia is best conceptualized as a neurodevelopmental disorder.

It is characterized by a complex interplay of genetic, environmental, and neurobiological factors that disrupt brain development and function during early stages of life.

While the exact causes are not fully understood, research suggests that abnormalities in brain structure, neurotransmitter imbalances, and genetic predisposition contribute to the onset of schizophrenia.

These disruptions may affect cognitive processes, emotional regulation, and perception, leading to symptoms like delusions, hallucinations, disorganized thinking, and social withdrawal.

Understanding schizophrenia as a neurodevelopmental disorder highlights the importance of early detection, intervention, and holistic treatment approaches to improve outcomes and quality of life for individuals affected by this condition.

Parasitism is the type of symbiosis that occurs between a deer and the tick. So, the correct option is C. This is because bacteria infect their host cell which is found in Deer.

What do you mean by Symbiosis?

Symbiosis may be defined as a relative ecological association between the individuals of two or more different species.

The type of symbiotic relationship found between oxpecker and zebra is Mutualism. This is because oxpecker is able to get its prey (food), while zebra is benefitted from the removal of insects from their body. So, the correct option is A.

The type of symbiotic relationship between Humans and bacteria living in their digestive tract is Mutualism. This is because Humans are benefitted from bacteria as they assist in digesting food, while bacteria also benefit to find a proper place where unlimited food is available. So, the correct option is A.

The type of symbiotic relationship between Barnacles and whales is Commensalism. This is because Barnacles are benefitted from excess food and easy transportation, while whales are neither benefitted nor harmed by this relationship. So, the correct option is B.
