Frequency is defined as the number of cycle of waves that occur in one second.
Here the total number of cycle is equal to 10
The total time in which these 10 cycles occur is equal to 5 seconds
Now, mathematically frequency is equal to

A species of organism has survived in a mild environment for thousands for years. Suddenly, the climate changes and the area becomes a cold and barren tundra. Which of the following traits might help the species survive?
A-short neck to help keep heat inside the body
B-thick fur to keep the organism warm
C-small size so the organism requires less food
D-all of the above
The trait that might help the species survive is ; ( B ) Thick fur to keep the organism warm
Tundras are barren land with harsh weather conditions such as extreme cold. and the most important factors any species that lives in a tundra is shelter and insulation.
For the species to survive in Tundra they need to keep warm because certain species can survive without food for long periods. To keep warm the species will have to develop a thick fur and a larger body size.
Hence we can conclude that the trait that might help the species survive is thick fur to keep the organism warm.

Why do cells need to replicate their DNA?
Answer:
Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell. ... Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.
Explanation:
DNA is the genetic material, which is found in every living cell. The DNA is made up of a pentose sugar, nitrogenous base, and phosphate backbone.
DNA is a genetic material that transmits the information from parent cell to daughter cell using DNA replication.
DNA replication is an essential process in which the daughter cells inherit information from the parent cell.
Cell division is a process through which a DNA copies its genetic material and delivers it to the newly forming daughter cells.
The genetic information in the daughter cell must contain the same set of rules and instructions to carry out the vital processes. The information is present in the original copied form of DNA from the parent.
Thus, DNA replication is necessary for the continuity of life and similar genetic information presents the daughter cells.

Smallpox is a virus that causes a rash that then turns into painful blisters. The last known case of smallpox was in 1977. What is the best explanation for the eradication of smallpox?
People are exercising more than they used to.
Genetic testing determines who is more prone to smallpox.
There was an increase in antibacterial products.
An effective vaccine was developed.
Answer:
An effective vaccine was developed
Explanation:
(I actually learnt about this is history!)
Smallpox was around 75-100 years before 1977, and people continued to die from it especially when there were severe outbreaks (thousands of people lost their lives). The main technique for vaccination was to make a small cut in the patients arm or wrist, and then to rub a smallpox scab into the open wound (inoculation). However this was not as effective as it sometimes, brought infections into the wound, but the success rate was still pretty high.
Edward Jenner was convinced that there could be a more effective way of vaccinating people against the smallpox. Jenner discovered (from a milk maid!), that those that have been infected with cowpox won't catch small pox, as they are from the same family. Instead of small pox being the vaccine, Jenner used weakened cowpox pus instead. This was much effective as the side effect of having cowpox mild, and the patient made a full recovery.
Jenner put this cowpox vaccine in injections so that an open wound is not needed.
By the 1850's the vaccine was made compulsory, but many were against it: still believing that miasma (foul air) was the cause of the small pox. It was made compulsory or face a fine in the mid 1950's, hence small pox was eradicated by 1977

Due to climate change, places that used to be colder are now warming up, allowing new invasive species to establish themselves. What is one way that warming conditions are beneficial to invasive species?(1 point)
Warm weather allows animals to travel farther and longer because they do not need to hibernate for winter.
Warming leads to longer life spans for the animals because none die due to exposure to the cold.
There is more food and shelter available since the growing season is year round.
If the location used to be too cold for non-native species, it is now warm enough to allow them to exist.
(Q1)An introduced species is not necessarily harmful to the environment; an invasive species has a negative effect.
(Q2) the number of species in a community
(Q3) If the location used to be too cold for non-native species, it is now warm enough to allow them to exist.
(Q4) It reduces biodiversity by reducing successful mating in native species.
(Q5) Large because it has led to several significant changes, including new invasive species and loss of natives.
Explanation:
i just did the quick check
Warming conditions are beneficial to invasive species because if the location used to be too cold for non-native species, it is now warm enough to allow them to exist. Option D is correct.
What are invasive species?When species move and establish in a new area, out of their original distribution range, they might be considered exotic or invasive, according to their
• reproductive rate,
• population growth, and
• interaction with native species.
When a new species stablishes and overgrow in a new area, negatively affecting native ecosystems dinamics, they are considered invasive species.
The introduction of invasive species has ecological, economic, socio-cultural consequences.
In the new areas, these species have less environmental pressure and better conditions than in their origin area -fewer predators, more resources, better nitches-.
These factors favor their establishment because they are adapted to surviving under harder conditions.
They interact with native species by
Competing for resources such -water, place, radiation, exposure, shelter, food, etcetera-.Predating on native species, consuming a wide diversity of prey items, and in many cases, there are no native species that may prey on them.They provoke significant damages in the structure of native ecosystems, causing severe damage in endemic species.
They produce ecological imbalances in the trophic chains and the dynamics of communities. Invasive species are uncontrollable.
Areas that get warmer due to climate change provide a propicious environment for invasive species to stablish and overgrow.
Temperature is not a limmiting factor any more for these species, so they can move and stablish in these areas.
Warming conditions are beneficial to invasive species because if the location used to be too cold for non-native species, it is now warm enough to allow them to exist.
Option D is correct.
