the first evidence of primitive cellular life was the 1977 discovery of microbial fossils in the swartkoppie chert, a type of granular sedimentary rock rich in silica. why is this evidence not considered definitive?
A short chain of the cyanobacterial cells found in the Bitter Springs Chert in northern Australia (about 1 billion years old). The bulk of modern genera really resemble cyanobacteria that are closely related to those that are living today. Unlike this fossilized cyanobacterium.
The fact that microorganisms can even leave fossils may surprise you. The oldest cyanobacteria-like fossils, which are among the oldest fossils ever found, are from the Precambrian, but one specific type of bacterium, the cyanobacteria or "blue-green algae," has left a fossil record that extends all the way back to that time. Larger than other bacteria, cyanobacteria have the ability to produce a thick cell wall. More crucially, cyanobacteria have the ability to form enormous, layered structures known as stromatolites or oncolites, depending on whether or not they resemble domes (if round).

People who are lactose intolerant lack the lactase enzyme. They often experience digestive problems when they eat dairy products. Do the results of demetri’s experience support this scenario? Explain your response
Answer:
Yes, the results of demetri's experience support this scenario.
Explanation:
A milk allergy is an immune response which involves the production of antibodies specific to substances in milk, such as casein. Lactose intolerance does not involve the immune system but is the result of an inability to produce the enzyme lactase. People with milk allergies suffer from different symptoms than people who are lactose intolerant. The symptoms of a milk allergy include hives, wheezing, and vomiting, whereas the symptoms of lactose intolerance are gastrointestinal distress, including gas and diarrhea.
While mRNA strands are being created a sequence is sometimes miscopied.
What will be the effect of this on the cell?
a
Translation may not take place.
b
Future transcription will not take place.
c
Ribosomes may be destroyed.
d
The damaged mRNA may cause cell death.
Answer:
a . Translation may not take place.
Explanation:
The mRNA or messenger RNA holds the Exton which is the coded section of the RNA meant to be translated to protein. When a mismatch or miscopy of the strands takes place, the section becomes unfit for translation (the section is similar to the intron which is not coded for translation), hence, translation does not take place.

What would be a correct unit of measurement for velocity?
Meters/second
North Meters / second
North
hours
Answer:
meter per second
Therefore, velocity is expressed in meters/second or m/s. The SI unit of velocity is meter per second (m/s). Alternatively, the velocity magnitude can also be expressed in centimeters per second (cm/s).
Explanation:
Brainliest please?
A correct unit of measurement for velocity is meters/second. Velocity is the rate at which an object changes its position in a specific direction over time.
The standard unit for measuring velocity in the International System of Units (SI) is meters per second (m/s). It represents the distance traveled in meters divided by the time taken in seconds, indicating both the magnitude and direction of the object's motion.
The options "North Meters/second" and "North" are not appropriate units of measurement for velocity. "North" represents a direction but does not provide information about the speed or magnitude of the object's motion. Additionally, "hours" is a unit of time and not directly related to measuring velocity.
Therefore, the correct unit of measurement for velocity is meters/second.

select each of the nervous system structures that are part of the central nervous system. a. brain stem b. spinal nerves c. cerebral hemispheres d. cerebellum e. cranial nerve ii
All of the given structures are the part of the central nervous system.
What is Nervous System?According to biology's classical idea of the nervous system, an animal's nervous system is a highly sophisticated component that coordinates its movements and sensory data by sending and receiving signals from and to various regions of the body. In order to react to such occurrences, the nervous system and endocrine system collaborate to detect environmental changes that have an effect on the body.
Around 550–600 million years ago, worm-like invertebrates were the first to develop nervous tissue. The discovery of electrical impulses in plants and their utilization in recent decades, however, has called into question this conventional wisdom. These findings have led some researchers to suggest that plants have neural systems and that the science of plant neuroscience should be established.

Option C: A tree and its physical environment alter each other are the most accurate statement about interaction.
As Charles Darwin concluded in his book “Origin of Species” which influenced much scientific development later. That the 'variations in living organisms around the world can be explained by differences in the natural environment.’ It simply means that the physical environment influences the nearby living organism. Later on, it was added that the living organism also influences the physical environment.
For example, to explain Human-Environment Interactions due to human actions, there is a rise in global warming and with the rise in global warming, ice caps are melting and affecting humans.

as ambient temperature decreases, metabolic rate in an ectotherm decreases to maintain body temperature.
The order is False.
In Ectotherms, decrease in ambient temperature causes body temperature to decrease, that causes a decrease in Metabolic rate.
What are ectotherms?Any animal that is considered to have cold blood, or whose ability to regulate body temperature depends on environmental factors like sunlight or a heated rock surface. Ectotherms are organisms whose internal physiological sources of heat play a small or almost insignificant role in regulating body temperature. Such organisms depend on heat sources in their surroundings, which enables them to have incredibly efficient metabolic rates. Fish, amphibians, reptiles, and invertebrates are all ectotherms. Endothermic organisms include human. This suggests that humans are less dependent on the external environmental temperature than ectothermic (poikilothermic) animals like fish and reptiles.Learn more about the Ectotherms with the help of the given link:
