What characteristics of the lungs of infants and small children creates increased risk of respiratory disorders
Answer:
The internal diameter of the airways in a child is smaller. Any inflammation or obstruction may cause more severe distress. In general, pediatric airways are smaller, less rigid, and more prone to obstruction. Children also have higher respiratory rates than adults making them more susceptible to agents in the air.

Denaturation of protein is the phenomenon where all the structures of proteins are disrupted except the primary structure. This happens because the primary structure is made up of covalent bonds that cannot be broken down easily. But the secondary or tertiary structures are made of non-covalent structures that are relatively easier to disrupt.
Enzymes are the proteinaceous agents that alter the rate of reactions. The enzyme activity is active when the protein exhibits the tertiary or quaternary structure. This is the reason why when protein denatures the enzyme activity also changes.

continue to grow year after
year without dying fall into
which of these categories
of angiosperms?
A. millennials
B. annuals
C. perennials this is answer
Answer:
perennials
Explanation:
Plants that persist for many growing seasons. Generally, the top portion of the plant dies back each winter and regrows the following spring from the same root system (e.g. Purple Coneflower). Many perennial plants do keep their leaves year-round and offer attractive borders and groundcover (e.g. Tickseed, Shasta, and Ox-Eyed Daisy).

Would the lac operon work if the repressor protein could not bind to lactose?
Answer: no
Explanation:
because binding of lactase to the repressor protein always the RNA polymerase to bind to promoter thus the structural genes could the production of enzyme lactase however if lactase doesnt bind the active repressor protein binds to the operator hindering the rna polymerase from binding on the promoter so there will be no genes for lactase production transcribed

Look at this map of current volcano hazards. Click a few volcanoes to determine their warning levels. Why is it possible to have a warning system for volcanoes? If you were a volcanologist, would you watch certain volcanoes on the map more than others?
It is possible to have a warning system for volcanoes because most volcanoes issue warnings before erupting.
As a volcanologist, certain volcanoes on the map will be monitored more than others because some volcanoes are more explosive than the others.
Why do volcanologist monitor volcanoes?Monitoring volcanoes enables volcanologist to understand its activities during an unrest through seismicity, deformation and degassing. Some volcanoes are explosive while others are not so the volcanologist has to monitor the type of magma that flows from it.
The volcanologist also uses the map as an indicator to know when any volcano is scheduled to erupt because some volcanoes provide warnings before eruption.

#SPJ1
Answer:
By examining the pace of change in the gases released, the rate of change in seismic activity, the rate of change in ground deformation, and other variables, a volcanic eruption can be predicted. These are early warning indicators of an eruption. Volcanologists should concentrate on Kilauea and Shishaldin when studying the map because these two volcanoes are at the watch alert level and are more likely to erupt.

If mitosis but not cytokinesis occurred in onion root tip cells, what would you expect to see on a slide of these root cells?
Answer: Well, cytokines happens after mitosis so you wouldn't see the daughter cells dividing yet.
Explanation: Onion root-tip cells divide once every 24 hours, or roughly two hours after sunrise, and go through a cell cycle that lasts for about 24 hours. Therefore, in order to harvest the greatest amount of proliferating cells, water-grown roots should only be removed at that time.
In tomatoes, red fruit (R) is dominant to yellow fruit (r). Cross a homozygous dominant fruit with a heterozygous fruit. What percentage will the offspring have yellow fruit?
The percentage of offspring that will have yellow fruit if a homozygous dominant (RR) fruit is crossed with a heterozygous (Rr) fruit is 0%.
What is a punnet square?A punnet square is the graphical representation used to determine the probability of an offspring expressing a particular genotype.
According to this question, in tomato plants, red fruit (R) is said to be dominant to yellow fruit (r). This means that the homozygous dominant genotype will be RR while the heterozygous fruit will have a genotype of Rr.
Hence, if a cross between RR (red) × Rr (red) occurs, the following offsprings will be produced:
RRRRRrRrBased on the above genotype of the offsprings, it can be observed that none of them have a yellow fruit phenotype, hence, the percentage will be 0%.

If pH affects enzyme activity, then...
pH: Each enzyme has an optimum pH range. Changing the pH outside of this range will slow enzyme activity. Extreme pH values can cause enzymes to denature. Enzyme concentration: Increasing enzyme concentration will speed up the reaction, as long as there is substrate available to bind to.
Answer:

When a neuron is not processing information:
O It is negatively charged
O It has no charge
O It is positively charged
O It is sometimes positively charged, sometimes negatively charged
When a neuron is not processing information It is negatively charged.
The correct option is A.
What is the role of neurons?Signals are sent and received by neurons, often referred to as nerve cells, from your brain. Although they share many characteristics with other cell types, neurons are physically and functionally distinct. Neurons are able to communicate electrical and chemical messages to other cells via specialised extensions known as axons.
Where are neurons found?The bulk of neurons in vertebrates are found in the central nervous system, however some are found in peripheral ganglia and many neurones are found in sensory organs like the retina and ear.
What is a neuron made of?Three basic components make up a neuron: a cell body, two extensions known as an axon, as well as a dendrite (3). The nucleus (2), which regulates the functions of the cell and houses its genetic material, is located inside the cell body. The axon resembles a tail and carries signals out of the cell.
