A sample of Carbon-14 originally contained 100 g. After three half-lives have
passed, how much Carbon-14 is left?
Answers
Answer:
After 3 half lives 12.5 g of C-14 left
Explanation:
Given data:
Mass of C-14 = 100 g
After 3 half lives mass left = ?
Solution:
At time zero = 100 g
At first half life = 100 g/2 = 50 g
At second half life = 50 g/ 2 = 25 g
At third half life = 25 g/2 = 12.5 g
Thus, after 3 half lives 12.5 g of C-14 left.

Answers
Answer:
Bottle-necking effect.
Explanation:
Like in the picture below the bottlenecking effect works the same way in nature. When we shake the bottle some kinds of candies may fall out and some may not. This doesn't represent the whole bottle. Some type may not even fall out because the bottle wasn't wide enough for it to fall out. This can happen in nature too. In a forest fire where some animals survive they didn't survive because they were adapted to fire. They just weren't in the part of the forest that was on fire. So with the new allele frequency in the new population, this is a bottleneck effect.
Sea turtles spend most of their lives at sea feeding on jellyfish. When it is time to lay their eggs, mature females come ashore. They dig nests in the sand along the coast, lay their eggs, and then return to the sea. The data below show the changing sea levels since the late 1800s.
If the current trend shown in the graph continues, what prediction is most likely regarding the future of sea turtles?
a. Fewer jellyfish will wash up on the beach for the turtles to feed on.
b. More predators will be found on the beaches to threaten the baby turtles.
c. The baby turtles will have to travel farther to reach the ocean.
d. The beaches on which turtles currently lay their eggs may go underwater.
Answers
Answer:
d. The beaches on which turtles currently lay their eggs may go underwater.
Explanation:
According to the graph, the beaches on which turtles currently lay their eggs may go underwater due to increase sea level with the passage of time. In the graph, we can see that sea level increases from 1880 to 2014 and the main reason for this increase is the climate change. Due to global warming the water present on the glacier starts melting and thus increase in sea level occurs so the beaches on which turtles currently lay their eggs may go underwater.

the number of consumer can never exceed the number of producer in nature why
Answers
Answer:
The number of consumer can never exceed the number of producer in nature because there is a limited amount of producer in the nature so the consumers is the one who eats a producer !
When the number of consumers increases, producers disappear due to overconsumption and consumers disappear due to lack of food and the ecosystem is destroyed. Therefore, in nature the number of consumers can never exceed the number of producers.
What are Producers and Consumers?Producers are plants that make their own food, the energy they need to grow, reproduce, and survive. They are making their own food which makes them special. These are the only living things on Earth that can make their own source of food energy with the help of sunlight, water and air.
Consumers make up the upper trophic level. Unlike producers, they cannot make their own food. They obtain their food by eating plants or other animals, while some eat both.
Scientists distinguish between several types of consumers. Primary consumers form the second trophic level.
Thus, when the number of consumers increases, producers disappear due to overconsumption and consumers disappear due to lack of food and the ecosystem is destroyed. Therefore, in nature the number of consumers can never exceed the number of producers.

What are some of the ways that parasites have adapted to transmission between hosts and resisting the host’s attempts to get rid of the parasite? How do these particular developments help the parasite?
Answers
Organisms depend on other species for resources such as nutrients. Parasites live in or on another organism, which is called the host. The parasite takes what it needs from the host but the host receives nothing in return and often suffers as a result. An example of parasitism is the relationship between fleas and dogs. Fleas live on dogs and feed on their blood. The dog receives no benefit but the fleas are provided with food and a habitat. Fleas attach themselves to hairs and can spread from one host to another by jumping huge distances.
During an experiment to determine if people with more symmetrical body features have a lower incidence of disease, a researcher first measures the length of several bones in the subject's hands and arms. The device used to measure length does not display a readout of the measurement taken. Instead, a wire connects the measuring device to a computer that records the data. The computer monitor is kept out of sight of the subject and the researcher. Why is such an elaborate device used?a. So that the subject will not know if he or she is part of the control group.b. So that the experiment will be repeatable.c. So that the subject will not be injured by the experiment.d. So that the identity of the subject will remain anonymous.e. So that the measurements are not biased by the researcher.
Answers
Answer:
e
Explanation:
The main reason such an elaborate device was used would be to eliminate any element of bias by the researcher.
It is important to eliminate biases when taking measurements so as to ensure the accuracy of the data and the overall outcome of the experiment. If a simpler device had been used in which the researcher manually records the length of the bones, it is possible to knowingly or unknowingly introduce biases or random error into the experiment which will impact the integrity of the data and the outcome of the experiment.

Answers
Answer:
D
Explanation:
To copy original DNA strands into complementary strands
The option (D) is correct. To copy original DNA strands into complimentary strands.
What are complementary strands of DNA?Complementary DNA (cDNA) is a DNA copy of a messenger RNA (mRNA) molecule produced by reverse transcriptase, a DNA polymerase that can use either DNA or RNA as a template.
Moreover, the complementary strand for DNA must follow the base pairing and polarity rules. Pairing means that A=T and G=C. Polarity means that the strands have to run in opposite directions. First write the correct base pairing below the original sequence and label the 5' and 3' ends.
Therefore, the upper strand of DNA is the "mRNA-like" strand. The lower strand is the strand that is complementary to the mRNA.

A powerful windstorm moves through a densely populated white oak forest. The oaks in this forest have either smooth or rough bark. The storm randomly knocks down 50% of the white oak trees. The remaining oaks grow and produce seeds that germinate and fill in spaces in the forest. All of the new oaks have smooth bark. Which of these processes is described in this example?
Answers
Answer:
Secondary succession.
Explanation:
These processes is known as Secondary succession because disturbance occurs in the environment due to powerful windstorm which eliminates rough bark oak tree while no damaged happen to the smooth bark oak tree. So the next time the plants grow in the place of rough bark oak tree because rough bark oak tree can't withstand in that type of environmental condition and all population is available of smooth bark oak tree due to their survival mechanism.

how does increasing the size of the habitat affect carrying? explain your answer. recall the scenarios: 0-15 years, little land; 15-30 tears, moderate land;30-45 years, ample land
plzzz helpp
I meant years not tears
Answers
Answer:
so basically carrying capacity is "the amount of organisms a specific environment can support", so if the environment is increased, most likely, more space and food will be available, which means the environment can hold more organisms, causing the carrying capacity to increase
Explanation:
what I just said lol
Answer:
Increasing the habitat size will increase the carrying capacity. Carrying capacity is the maximum amount of organisms a habitat and its resources can carry. So if the habitat expands and more resources become available, the population would expand. As you can see for the first 15 years, when it was the little land, there was only about () rabbits, but as the land grew throughout the years, the rabbit population grew. 15-30 years with moderate land had around () rabbits, and the ample land in years 30-45 had around () rabbits, a little over two times the amount the little land had.
