What are the benefits for blacktip sharks?
Answer:
Blacktip reef sharks are a critical source to help maintain the delicate balance of marine life in reef environments. They keep fish populations in check and the reefs healthy. However they are highly valued for their meat, fins, leather, liver oil, and fishmeal which makes them prone to overfishing and targeting, and they are endangered yet they are also highly valuable in tourism.
Explanation:
if an element has a half-life of 30 million years and there is 12.5% of it remaining in a rock, how old is that rock
Answer:
The half-life of a substance is the amount of time it takes for half of that substance to decay. However, after two half-lives, half of the half remaining will decay, leaving you with one quarter of the original substance.
So, after 1 million years you will have 50% of the original substance remaining.
And, after 2 million years you will have 25% of the original substance remaining.
After 3 million years you will have 12.5% of the original substance remaining.
And after 4 million years you will have 6.25% of the original substance remaining.

"Biological" redirects here. For other uses, see Biological (disambiguation).
Biology is the scientific study of life.[1][2][3] It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field.[1][2][3] For instance, all living organisms are made up of cells that process hereditary information encoded in genes, which can be transmitted to future generations. Another major theme is evolution, which explains the unity and diversity of life.[1][2][3] Finally, all living organisms require energy to move, grow, and reproduce, as well as to regulate their own internal environment.[1][2][3][4][5]
Biology deals with the study of life and organisms.

Biologists are able to study life at multiple levels of organization.[1] From the molecular biology of a cell to the anatomy and physiology of plants and animals, and to the evolution of populations.[1][6] Thus, there are multiple subdisciplines within biology, each defined by the nature of their research questions and the tools that they used.[7][8][9] Like other scientists, biologists use the scientific method to make observations, pose questions, generate hypotheses, and perform experiments to satisfy their curiosity about the world around them.[1]
Life on Earth, which emerged before 3.7 billion years ago,[10] is immensely diverse. Biologists have sought to study and classify the various forms of life, from prokaryotic organisms such as archaea and bacteria to eukaryotic organisms such as protists, fungi, plants, and animals. These various living organisms contribute to the biodiversity of an ecosystem, where they play specialized roles in the exchange of energy and nutrients.

Describe the traits that would have existed in early eukaryotes.
Answer:
Early Eukaryotes were single-celled organisms that were present more than 1.6 to 2.1 billion years ago.
Explanation:
-Eukaryotes could be found in a variety of shapes and had a nucleus, a flexible membrane, and a cytoskeleton.
-Early eukaryotes used oxygen in metabolism.
Answer: Many traits found in eukaryotic cells today would have been found in early eukaryotic cells. First, early eukaryotic cells would have had membrane-bound organelles. Also, DNA probably contained introns since this is seen in many eukaryotic cells today. Chromosomes were probably linear in shape. Lastly, these cells would have had mitochondria and membrane-bound organelles. Since these are seen in all eukaryotic cells today, we can infer that they would have been around in early eukaryotes as well.

Explanation:
The number of white-tailed deer in certain areas of Long Island, NY has increased significantly. Homeowners and farmers have put up tall fencing to protect their gardens and crops from the deer. One reason why the white tailed-deer might have increased significantly in certain areas of Long Island is * 3 points A the lack of natural predators B an increase in deer pathogens C a shortage of biotic resources needed by the deer D that carrying capacity has no effect on deer populations
Answer:
A. the lack of natural predators
Explanation:
The white-tailed deer inhabits a wide variety of environments. The species characterizes by its adaptation to different conditions, especially in contact with human beings and their activities.
Due to human action and the change in the environment, populations of white-tailed deer have expanded to Canada. Due to its adaptability capability, the deer have reproduced more than expected in some regions, up to the point of being detrimental for people.
In fact, In the United States and Canada, the overabundance of the species has brought consequences to people, such as plagues, accidents, diseases, material loss, among others.
Human action modified the deer habitat, but other species were affected too. It is the case of wolves or pumas, natural predators of the white-tailed deer. The natural habitats of these species have been destroyed, and they have been summited to extensive hunting for years. Habitat reduction and hunting drove these species to disappear.
One of the principal reasons for deer overpopulation is the absence of predators. Under natural conditions, pumas and wolves keep deer population growth under control. However, once these species were eliminated, the white-tailed deer was not affected by predation pressures anymore
The absence of natural predators and the adaptation capability to different environments and border effects made it possible for the white-tailed deer population to overgrowth.
The graph below shows changes in the populations of two species that interact only with each other over a period of time.
Which statement best describes these two species?
Species A is a producer and species B is its consumer.
Species A is a host and species B is its parasite.
Species A is a predator and species B is its prey.
Species A is a scavenger and species B is its decomposer.
The statement that best describes the two species depicted in the graph is option C) Species A is a predator and species B is its prey.
Option A indicates that species A is a producer and species B is its consumer. This means that species B requires the output from species A to survive. Knowing this, we would expect to show that species B increases in population as the population of A increases, due to increased food supply, the graph shows the opposite scenario. Thus, option A is false.
Option B states that perhaps Species A is a host and species B is its parasite. This provides the same conditions and dependencies as option a, so for the same reasons that a is false, we can conclude that option B is false as well.
The final incorrect option is D, Species A is a scavenger and species B is its decomposer. This would mean that as the population of species B dies off, it increases the food supply of Species A which feeds on the decomposing members of species B. We would expect in this case, that species A would flourish as B dies off, however, we see that as species B dies, species A follows shortly after. This tells us that option D is incorrect.
The correct option is C, Species A is a predator and species B is its prey. This would mean that species A consumes the members of species B to survive. Therefore we would expect to see
Species B thrive as the population of A remains lowFollowed by the steep decline of species B's population as more predators begin to appear. Once the population of species B reaches a critical point, species A will not have enough food supply to sustain its population, and both populations would decline.
This is exactly what the graph depicts, so option C is correct.

when a vegetable gets put in salt water and collapses why does this happen
Osmosis is defined as the movement of solvent (like water) from a region where the concentration of solute(like salt) is lower to a region where the concentration of solute is higher through a semipermeable membrane.
Salt water is a hypertonic solution as the concentration of salt ( solute) is higher. Therefore, in this case water from vegetable will move outside causing the cells to become fragile.

1. What is the independent variable in this experiment?
Answer:
Variables are given a special name that only applies to experimental investigations. One is called the dependent variable and the other the independent variable. The independent variable is the variable the experimenter manipulates or changes, and is assumed to have a direct effect on the dependent variable.
Explanation:
Answer:
The independent variable is the factor that doesn't rely / change based on another variable. Usually there is an independent, dependent, and constant variable. The dependent variable's "results" and values rely on the independent value.
For example if tomatos were to be grown the independent variable is the type of light the tomato plant is grown under. The dependent variable would be the rate of the growth of the tomato plant. (It relies on the type of light, the independent variable)

What is codominance?When two alleles codominate, neither can hide the manifestation of the other allele. However, neither allele is recessive in codominance, and both alleles' phenotypes are manifested.
When two alleles codominate, neither can hide the manifestation of the other allele. Codominant alleles are those that have an independent impact.
Both phenotypes are partially prevalent in codominance. Codominance is best illustrated by if a black cat is crossed with a white cat, all offspring will be black and white.
Therefore, if a black cat is crossed with a white cat, all offspring will be black and white.
