Answers
Answer: Homologous structures.
Explanation: The bones labeled A have similar structural arrangement in all the organisms but perform different functions in each organism
The bones labeled as A are known as homologous structures. Therefore, option D is correct.
What are homologous organs?Homologous organs are those present in several creatures that share a common ancestor and fundamental structure but differ in the roles they perform. The man's forelimbs, a cat's forelimbs, a whale's flippers, and a bat's wings are all examples of homologous organs.
Homologies are characteristics shared by two or more species and derived from their common ancestor. For instance, our common ancestor who lived more than 300 Mya ago left us with both the human five-fingered hand and the lizard's five-toed foot.
The forelimbs of penguins, bats, alligators, and humans are examples of homologous organs. Therefore, option D is correct.

Answers
Answer: If some of the species in the coral reef are destroyed, (The coral reef would begin to deteriorate without the variety of fish and plants necessary to maintain balance)
Explanation:
CORAL REEFS is a ocean habitat that provides shelter for a variety of aquatic animals such as clownfish, sea anemone, coral, sea urchins, sponges, and parrot fish which are just a few examples of the large variety of organisms that can be found in a coral reefs. These animals are responsible for building the reefs which takes different forms and helps in maintaining balance. This habitat is important to marine life as it provides food and shelter for them.
Recently, many human activities has posed a threat to the coral reef and it's inhabitants These activities include:
--> Pollution: this is cause any agricultural run offs, Chemical and oil spills which can damage coral growth and reproduction.
--> coastal development: an unplanned coastal development has a damaging effect on the coral reef habitat.
--> Sedimentation: This can lead to increase in turbidity of coastal waters which in turn reduces light availability to the coral reef.
--> Destructive fishing practices: inadequate management of different fishing practices has led to the depletion of key reef species and habitat damage.
From the above explanation, the aquatic species found in the coral reef are responsible for building and maintaining the reef. If they are DESTROYED due to the above mentioned human activities, the reef will begin to deteriorate.

Many years ago a scientist Group E plants that produce wrinkled peas the peas from the plants produce new plants that also produce wrinkled peas the scientist concluded that something in the para plan will be transmitted to the next generation this discovery is known as
Answers
Answer:
This discovery is known as heredity.
Explanation:
In the question above, we can see an example of heredity, which is the process where a trait is passed from an ascendant to a descendant. As seen above, the wrinkled seed is a characteristic that was passed on to a plant through its parent, the plant that gave rise to it. The characteristics passed by heredity are transmitted through the continuous transfer of genetic material, present in the DNA. Since the descendants have the DNA of their parents, it is possible that the characteristics are transmitted as the generations advance.
Despite the best efforts of scientists to create an all-encompassing system of names for relationships between organisms, some still fall in a grey area. Some species of wasp are known as "parasitoids" and not true parasites. These wasps kill caterpillars to reproduce but do not harm any other caterpillars until they need to reproduce again. Why aren't these wasps considered true parasites?
Answers
Answer:
Wasps only use the caterpillars when producing offspring which kills the caterpillars.
Explanation:
'True parasites' are generally defined as organisms which live off 'host' organisms of another species at the expense of that organism by harming them in some way. They do this in a variety of ways for different reasons, the most common ones being as a source of food or favorable living conditions. Their lives are almost always entirely dependent on their host. Conventional parasites also usually don't kill their hosts as it is in their best interest that their host stays alive for them to gain the most advantage from them.
Wasps do not fit the true definition of a parasite because:
1. They don't rely on living off the caterpillars to live normally. Wasps are able to find their own sources of food and live on their own without other species. It is only when reproducing that they use and harm the caterpillars.
2. This process kills the caterpillars as the wasp larvae eat them when they emerge and grow which is unconventional for parasites.
It is because of these exceptions that these wasps are classified as 'parasitoids' and not conventional parasites.
Note: Wasps like these have been introduced many times because of this symbiotic relationship they have to help control caterpillar populations.

In the early 1900s, the Florida panther was found all over Florida. By 1967, the population had dropped to only 30 panthers statewide, and the panther was listed as an endangered species. What is the most likely reason for the decline in the panther population?
A. Florida's climate changed dramatically.
B. Panthers were hunted by humans for many years.
C. The panthers moved north into Georgia and South Carolina.
D. Alligators stopped eating other animals and started eating panthers.
Answers
Answer:
B.
Explanation:
Florida's climate itself hasn't particularly changed a bunch, but in the 20th century the population of Florida has increased. Plus D and C are easy to rule out. The easiest explanation for the panther's decline is the fragmentation of their habitat, and human interaction with the environment, not hunting per se. Good news is that the Florida panther's population has gone up to over 100!
Best of luck, and feel free to ask for any clarification.

Which explains how interference is avoided between the signals that cordless phones receive and the signals that they broadcast?
Answers
Answer:
the signals have different frequency
Explanation:
The way that interference is avoided in these cases is that the signals have different frequency. Cell phone signals travel in a very specific wavelength, how often this wave repeats in a given span is called the frequency. By having these signals in different frequencies it prevents the signals from mixing with each other and instead allowing them to reach their destination intact. Otherwise, the signals would combine into a mess of uncomprehensible data, which is what we call interference.

D.anywhere its service broadcasts and it can receive a signal.

Explanation:
A mutation is defined as any alteration in the genetic material of a cell of a living organism. Moreover, a silent mutation refers to any mutation that does not alter the phenotype of the cell/organism (they are evolutionary neutral mutations). Silent mutations are base substitutions that do not alter the amino acid sequence of the resulting protein, and therefore these mutations do not alter protein function.
