The easiest and most effective way to prevent foodborne illnesses is to
True or false? leaves appear green because they absorb green wavelengths of light.
The correct answer is false
Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light.
Do leaves absorb green wavelengths?In the absorption spectra, chlorophyll absorbs light in the red (long wavelength) and the blue (short wavelength) regions of the visible light spectrum. Green light is not absorbed but reflected, making the plant appear green.
Why can leaves absorb green light?In conclusion, plant leaves are green because green light is less efficiently absorbed by chlorophylls a and b than red or blue light, and therefore green light has a higher probability to become diffusely reflected from cell walls than red or blue light. Chlorophylls do not reflect light.

A change in allele frequencies in a population over a span of generations is
A change in allele frequencies in a population over a span of generations is called microevolution.
What is microevolution?
Microevolution is the change in allele frequencies that occurs within a population over time. This variation is the result of four distinct processes: mutation, selection, gene flow, and genetic drift. When compared to macroevolutionary changes, this change occurs in a relatively short period of time.
Pesticide resistance, herbicide resistance, and antibiotic resistance are all examples of natural selection at work. The enterococci bacteria depicted here have developed resistance to a variety of antibiotics.

how could floodwater runoff from the land negatively impact the biodiversity of the great barrier reef lagoon ecosystem?
Answer:
Increase nutrient concentration
Explanation:
Flood water runoff can take with it material from areas occupied by industries and crops. These areas have a large amount of chemical and organic waste arising from the result of agricultural and industrial activities. In this way, when the floodwaters carry this type of wastewater and flow into an aquatic environment with the presence of coral reefs, it causes an increase of nutrient concentration in that environment. This causes negatively affects the aquatic environment, causes eutrophication and harms coral reefs.

The human body can protect itself from infection. the ability to resist infection related to
age, strength of immune system, health, personal hygiene, diet.
Our body has many ways to protect itself from infections. It needs us to know and understand the normal ways your body does this, and how cancer and cancer treatment change this process. This may assist us appropriate understand why infections can expand so quickly and be so serious in people with cancer.
If we get infected through the skin or mucous membranes, the job of protecting the body shifts to our immune system. Our immune system is a composite grid of cells, signals, and organs that work jointly to help kill germs that cause infections. Many of these are special blood cells that travel in the blood until they find germs to attack. Others fill part of their moment in the blood and the rest of their time in immune system body part.
White blood cells are part of the immune system. (Red cells and platelets are not.) There are different types of white blood cells, and they each have a key role in the body’s defense against germs:

Which of the following best explains why the number of kingdoms increased
Final answer:
The number of kingdoms in the Linnaean system increased due to the discovery of new species and advancements in understanding of biochemistry and genetics, leading to a more accurate classification system that includes the addition of domains and more kingdoms.
Explanation:
The reason the number of kingdoms in the Linnaean system of classification increased from 3 to 5 by the mid-1900s is primarily due to two factors: the discovery of many new species and the advancements in our understanding of organisms' biochemistry and genetic makeup. Carolus Linnaeus, the Swedish botanist who developed the system in the 1700s, initially classified organisms based on their morphological traits. However, as science progressed, especially with the advent of molecular biology, scientists recognized the need to revise Linnaeus's system to more accurately reflect organisms' evolutionary relationships and biochemical differences. This led to the expansion of the classification system and the addition of new taxa such as the domain, which is more inclusive than the kingdom and divides life into three categories: Bacteria, Archaea, and Eukaryota. Under Eukaryota, organisms are further classified into kingdoms including Animalia, Plantae, Fungi, and Protista.

Growing new plants from other plant parts is _____. propagation agronomy triticale synthesis
Ans.
Growing of a plant from other plant, such as from seeds, cutting, or tubers is known as plant propagation. It can be divided into sexual propagation and asexual propagation. Sexual propagation involves development of new plants from spores and seeds.
Asexual reproduction involves development of new plants from vegetative plant structures, such as stem, nodes, or bulbs. It is an inexpensive and easy method to get new plants from old plants.
Thus, the correct word to be filled in the blank is option). 'propagation.'
What is the medical term for the ventral fold of tissue that attaches the foreskin to the glans?
How does the melting of the ice caps affect the amount of salt in the water?
Melting glaciers and polar ice caps add fresh water to the ocean, potentially decreasing its salinity. The amount of change in salinity varies regionally and is influenced by various factors, including thermal expansion of water and increased acidity of the seas due to carbon dioxide absorption.
Explanation:As glaciers and polar ice caps melt due to global warming, a significant amount of fresh water that was previously frozen is added to the oceans. This influx of meltwater can dilute the seawater, potentially decreasing the overall salinity of the ocean. However, because the ocean is vast, the change in salinity is not uniform and can vary in different regions.
Melting sea ice, such as icebergs already floating in the ocean, does not directly contribute to changes in salinity since this ice is already part of the ocean's water volume. In contrast, the melting of land-based ice, such as glaciers, adds fresh water not previously accounted for in the sea level, which can reduce the salinity of the seawater around the melting points.
Meltwater from glaciers, combined with the thermal expansion of seawater as it warms, contributes to the rise in global sea levels. This phenomenon not only affects global circulation patterns by altering the density and thus the buoyancy of seawater but also poses a threat to marine ecosystems and coastal communities through increased acidic seas and changing shorelines.
is the earth getting larger and wider when plates drift away from each other?explain
The Earth does not get larger when plates drift apart because new crust formation at divergent boundaries is balanced by crust destruction at subduction zones.
The theory of plate tectonics explains how continent drift is caused by slow motions in the Earth's mantle moving large portions of the crust. A divergent boundary occurs when two tectonic plates move away from each other. Especially along mid-ocean ridges, where magma rises to form new seafloor, this process can indeed result in the formation of new crust. However, this new crust is balanced by the destruction of the old crust at subduction zones, where one plate moves beneath another and is reabsorbed into the mantle. As a result, the Earth is neither getting wider nor larger.MULTIPLE CHOICE VERY EASY!!!!!

Final answer:
The correct answer to the question is A, suggesting that members of a population that live long enough to reproduce are the ones best adapted to their environment as per the theory of evolution by natural selection.
Explanation:
The question you've asked relates to how traits are passed on within a population in the context of the theory of evolution by natural selection. Drawing from the concept of natural selection, the correct option that is consistent with the theory is: option A. They are the ones that are best adapted to survive in their environment.
This is because individuals in a population that possess advantageous traits are more likely to survive and reproduce. These advantageous traits are then inherited by their offspring. Over time, the population evolves as these traits become more common, and the population as a whole becomes better adapted to its environment.

________ is the term used to describe the crossing over of a tract to the side of the nervous system opposite to where the axons originated.
Nerve cells send electrical impulses along the _____. when these impulses reach the end of the neuron, they cause a release of neurotransmitters across the _____.
Answer: Nerve cells send electrical impulses along the axon. when these impulses reach the end of the neuron, they cause a release of neurotransmitters across the synapse.
Explanation:
There are three main parts of neurons:
1) Axon
2) Dendrites
3) Cell body
Axon in a nerve cell send electrical impulses which is known as action potentials from the nerve cell.
When these impulses reach the end of the neuron , they cause of release of neurotransmitters across the synapse.
Since synapses is the gap between two neurons to allow faster transmission of electrical impulses.
Hence, Nerve cells send electrical impulses along the axon. when these impulses reach the end of the neuron, they cause a release of neurotransmitters across the synapse.
