After large scale fishing, which populations of organisms are
becoming more rare? Why?
A hurricane passes through the Gulf of Mexico and destroys many of the coastal regions of Northwest Florida. Which of the following is a likely impact of this catastrophic event on biodiversity?
Group of answer choices
Species brought in by the storm surge will displace species native to the coastal wetlands.
Excessive salt from the storm surge will flood coastal wetlands and raise salinity to intolerant levels for the local species, causing a decrease in biodiversity
Coastal wetlands will grow exponentially with the input of nutrients from storm upwelling and biodiversity will increase in these areas.
Species reliant on coastal wetlands for survival may experience a decline in population due to loss of habitat.
Answer:
Species reliant on coastal wetlands for survival may experience a decline in population due to loss of habitat.
Explanation:
A hurricane destroys many coastal regions of Northwest Florida which leads to the loss of habitat of many species that lives on the coastal region of Northwest Florida. This hurricane destroy the habitat that leads to decrease in population of organisms that lives in that coastal region so we can conclude that the population of organisms decreases due to this hurricane.

is a rotting log considered living or non living? why?
Answer:
A rotting log is nonliving. However, it can have mold, lichen, or fungus growing on it, which is not the log itself. Those three things are living. And though the log was once a living tree, at it's current state, it is nonliving.

please help me
Earth is a beautiful planet that revolves around a star called Sun, which is located in one of the arms of our Milky Way Galaxy. It is the only planet known to support life in the Solar System. Humans are the most intelligent civilization on this planet. It's blue when seen from space. Recently, Earth 29 spacecraft was able to land on this planet, after 28 unsuccessful landings of Earth series of spacecrafts. We were able to learn many things about humans, most important of these was the most spoken language of them, which they call English. According to experts, humans are not yet ready to know about our existence. It can take about 1 or 2 more centuries, until they are ready to know about us.

How can you tell if an atom has a negative charge? What type of Ion is this?
If an atom has more electrons as compared to the proton then we can say that the atom has a negative charge.
What is an electric charge?Charged material experiences a force when it is exposed to an electromagnetic field due to the physical property of electric charge.
You can have a positive or negative electric charge (commonly carried by protons and electrons respectively).
We may say that an atom has a negative charge if there are more electrons in it than there are protons.
The positively charged atom is known as the cation while on the other hand the negatively charged atom is known as the anion.
Thus, If an atom contains more electrons than protons, we may say that it has a negative charge.

Not all traits are determined solely by genes. Many traits have been found to exhibit phenotypic plasticity, which
occurs when individuals with the same genotype exhibit different phenotypes in different environments. Which of the
following is an exampleof phenotypic plasticity?
Well-maintained hedges can be shaped into artistic displays.
O A person who experienced malnutrition as a child is short in stature as an adult.
O Bears living in the arctic developed white fur and cold tolerance over many generations.
Certain breeds of dog have been bred for specific traits, such as poodles being bred for intelligence.
Answer:
O A person who experienced malnutrition as a child is short in stature as an adult.
Explanation:
Height is a quantitative trait, i.e., a phenotypic trait that depends on the combined action of many genes and the environment. Moreover, phenotypic plasticity can be defined as the ability of one genotype to produce different phenotypes in different environments. In consequence, quantitative traits are influenced by environmental factors and exhibit phenotypic plasticity. Quantitative traits are characterized to have a large variety of phenotypes and follow a normal distribution (a bell-shaped curve) when they are drawn.
Elements such as carbon can move through the
environment and organisms in a cycle because
living and nonliving things interact in _______.
A. cells
B. species
C. organisms
D. ecosystems
Elements such as carbon can move through the environment and organisms in a cycle because living and nonliving things interact in ecosystem. The correct option is D.
What is an ecosystem?An ecosystem is made up of all the organisms and the physical environment in which they live.
These biotic and abiotic elements are linked by nutrient cycles and energy flows. Photosynthesis introduces energy into the system, which is then incorporated into plant tissue.
Healthy ecosystems clean even our own water, purify our air, keep our soil in good condition, regulate the climate, recycle nutrients, and provide us with food.
They supply raw materials and resources for pharmaceuticals and other uses. They are the foundation of all civilization and the lifeblood of our economies.
Because living and nonliving things interact in an ecosystem, elements such as carbon can move through the environment and organisms in a cycle.
Thus, the correct option is D.

What's a node on a cladogram?
Answer:
The node therefore represents the end of the ancestral taxon and the stems , the species that split from the ancestor. The two taxa that split from the node are called sister taxa.
Explanation:
Answer:
A n0de corresponds to a hypothetical ancestor. A terminal node is the hypothetical last common ancestral interbreeding population of the taxon labeled at a tip of the cladogram. ... Each internal n0de is also at the base of a clade, which includes the common ancestral population (node) plus all its

1. The pollutants in our atmosphere have the ability to change the entire planet’s
2. is a theory that states that the increasing carbon dioxide in the atmosphere is causing the climate to warm up.
Answer:
Ans1 Not only does it contain the oxygen we need to live, but it also protects us from harmful ultraviolet solar radiation. It creates the pressure without which liquid water couldn't exist on our planet's surface. And it warms our planet and keeps temperatures habitable for our living Earth
Ans.2 The carbon dioxide theory states that, as the amount of carbon dioxide increases, the atmosphere becomes opaque over a larger frequency interval; the outgoing radiation is trapped more effectively near the Earth's surface and the temperature rises.
what type of mutation has the least amount of impact on a protein ?

How does meiosis create four daughter cells from one parent cell?
Answer:
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. ... The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell.
Explanation:
Unlike in mitosis, the daughter cells produced during meiosis are genetically diverse. Homologous chromosomes exchange bits of DNA to create genetically unique, hybrid chromosomes destined for each daughter cell
How does air flow when a low-pressure center occurs in the atmosphere?
Answer:
A low pressure system has lower pressure at its center than the areas around it. Winds blow towards the low pressure, and the air rises in the atmosphere where they meet. As the air rises, the water vapor within it condenses, forming clouds and often precipitation.
