How do television stations broadcast live video across the entire world simultaneously? Please me help!!!
Answer:
Television broadcasting
The transmission of visual images of moving an stationary objects, generally with accompanying sound, in the form of electromagnetic waves that when received can be reconverted into visual images.
Very high frequency (VHF)
A band of radio frequencies falling between 30 and 300 MHz; VHF signals are widely employed for television and radio transmissions. In the United States and Canada, television stations that broadcast on channels 2 through 13 use VHF frequencies, as do FM radio stations. Many amateur radio operators also transmit on frequencies within the VHF band.
Telecasting on television electromagnetic transfer of moving or still objects' visual pictures, usually accompanied by sound, which, when received, can be transformed back into visual images, they broadcast on VHF and UHF frequency channels.
What is VHF in television broadcasting?Very high frequency (VHF), They broadcast on VHF and UHF frequency channels. Due to the fact that radio waves at these frequencies travel along lines of sight, their reception range is constrained by the horizon to between 40 and 60 miles, depending on the height of the transmitter station.
VHF signals, a range of radio frequencies between 30 and 300 MHz, are often used for radio and television transmissions. VHF frequencies are used by FM radio stations as well as television stations that broadcast on channels 2 through 13 in the United States and Canada.

with reference to evolution of long neck in giraffe explain how natural selection brings about adaptation of species to its environment
Answer:
Explanation:
In order to reach specific items of food that meet the dietary needs of the giraffe, they must reach for food up in the trees. Giraffes with longer necks are open to a wider array of food whereas the short necked giraffes are limited. The longer neck is seen to be more favorable. When a trait is more favorable, it has a higher likelihood of being passed on. The less favorable traits are eliminated or "weed" out and the taller giraffes mate with other tall giraffes, generating a greater population with this trait. Again, it is solely dependent on what is available around them and their surroundings.

Question 2: Symbiosis Symbiosis is another type of two-species interaction. It literally means living together, and refers to pairs of species that live in close physical proximity with the other species for a major part of their life cycles. Some examples of symbiosis: You and the microorganisms that live in your intestines; bark beetles burrowing in pine tree trunks; Monarch butterfly caterpillars and milkweed plants; and algae living in coral tissues. Can you think of any symbiotic interactions that are commensal or parasitic
Answer:
Commensal= mites and larger insecta who fly. Hermit crabs and shells of other organisms. Remora fish and whales. tree frogs and plants.
Parasitic= tick and dogs, tapeworm in humans, Barnacles and whales
Explanation:
Commensalism is when one species benefits and the other is neither helped or harmed. Parasitism is when one benefits and the other is harmed.

what are osteoblasts and osteoclasts? Describe how these cells work together in a healthy person. What can occur if these processes are unbalanced?
Answer:
Osteoblast and osteoclast are the two main cells participating in those progresses (Matsuo and Irie, 2008). Osteoclasts are responsible for aged bone resorption and osteoblasts are responsible for new bone formation (Matsuoka et al., 2014). The resorption and formation is in stable at physiological conditions.Answer:
Osteoclasts are cells that dissolve bone and osteoblasts are cells that form new bones.The building up and breaking down of the bone tissue aids in strengthening bones. If bone destruction by osteoclasts happens faster than new bone tissue is built by osteoblasts, this can cause problems for a person.

Fossils of the same type and same age have been found on different continents. If we were to put South America and Africa together, these fossils would even be in the same area! What does this tell us? How could this happen?
Can some one help me plz
Answer:
there have been several cases where fossils of the same type and age where found on different continents.
For example:-
"The Mesosaurus" which is an extinct genus of reptile from the Early Permian and was found in the continents of southern Africa and South America.
This seems to point to the fact that once all the continents were togethe, and they are now separate due to the Continental drift. ( the theory that states that all the continents were earlier one big form of landmass, but they have moved away from each other thus appearing to have "drifted" across the ocean bed."
But again these are all just theories and speculations but findings like these strengthen them and make people believe in these theories. They haven't exactly been confirmed. Like the evolution theory.

Explain why it is important to the crabs that they can regulate the osmolarity of their tissues.
Answer:
To maintain homeostasis.
Explanation:
It is important for the crabs that they can regulate the Osmoregulation of their tissues because they needs to maintain the homeostasis of the organism. This osmoregulation also maintains the concentration of water content and solutes in the body of crabs.

A local population of bobcats has decreased by 10% over the last 10 years. Is this change in population significant enough for the bobcat species to be considered for the Endangered Species List and protection from the government?
Yes, because any change in population even if it has a wide habitat range and large global population is cause for concern and the government should help that population recover.
Yes, because the local population decrease means the other populations are also decreasing even though the species has a wide habitat range and large global population.
No, because a small change in a local population of a species with a wide habitat range and large global population is not cause for concern.
No, because it will probably just go extinct and another predator will take over it's habitat even though it has a wide habitat range and large global population.
Answer:
No, because a small change in a local population of a species with a wide habitat range and large global population is not cause for concern.
Explanation:
Population change can be defined as the change in the number of individuals of a given species in an area during a specific time interval. Local populations may suffer small changes in their size but it generally does not represent an important problem for the survival of these species. A species is classified as endangered when its population size is reduced in a percentage from 50% to 70% within a period of time of ten (10) years. These values and the corresponding list of endangered species have been developed by The International Union for Conservation of Nature (IUCN), which represents the opinion of more than 8,000 researchers worldwide.

Explanation:
You are now trying to map a new gene locus (Gene X) on chromosome 9. You have determined that the recombination frequency between Gene X and Gene A is 12.5%, recombination frequency between Gene X and Gene B is 25%, and the recombination frequency between Gene X and Gene C is 31.25%. Use this information to determine the location of Gene X. Show your work and explain your reasoning.
Answer:
The correct order of genes might be: C, B, A, X (or X, A, B, C)
--C------------B--------------------A-------------------X----
∫-----------------------31.25mu---------------------∫
∫-----------------25mu-----------------∫
∫-----12.5mu----∫
Explanation:
Available data:
the recombination frequency between Gene X and Gene A is 12.5%,the recombination frequency between Gene X and Gene B is 25%, the recombination frequency between Gene X and Gene C is 31.25%.We need to know that 1% of recombinations = 1 map unit. The map unit is the distance between the pair of genes for which one of the 100 meiotic products results in a recombinant one.
The recombination frequencies between two genes determine their distance in the chromosome, measured in map units. So, if we know the recombination frequencies, we can calculate distances between the four genes in the problem and we can figure the genes order out. This is:
Recombination frequencies:
1% of recombination frequency = 1 map unit (MU)
A-X = 12.5% = 12.5 mu
B-X = 25% = 25mu
C-X = 31.25% = 31.25 mu
We do not know the distances between A-B, A-C, and B-C, so we can just estimate the location of the gene X by its distances from genes A, B, and C. To do this we need to think about it as additions. We know that A-X = 12.5 mu, a distance duplicated by B-X = 25 mu (12.5 + 12.5 = 25), and X is farther away from B than from A, so, this might tell us that A is located between B and X.
---B--------------A--------------X------
∫-------------25mu----------∫
∫--12.5mu----∫
Now, we know that X-C = 31.25 mu. And, assuming that these are linked genes, the maximum recombination frequency is always 50%. So the distance between two genes can not exceed 50%. According to this, we might assume that the C gene is near B, because if it was on the other side of X, the distance between B-C would sum 56.25 mu (25 + 31.25), meaning that they would not be linked. So, the correct order might be
--C------------B--------------------A-------------------X----
∫-----------------25mu-----------------∫
∫-----12.5mu-----∫∫-----12.5mu----∫
∫-----------------------31.25mu-------------------∫
∫6.25mu∫
∫------------18.75mu---------∫
The location of Gene X is closest to Gene A located 12.5
Given that :
The recombination frequency between Gene X and Gene A is 12.5%
The recombination frequency between Gene X and Gene B is 25%
The recombination frequency between Gene X and Gene C is 31.5%
The recombination frequency represents the map distance between the genes on the linkage map and the lesser the value of the recombination frequency the more linked are the genes.
The sequence in the linkage map is attached below
Hence we can conclude that the location of Gene X is closest to Gene A located 12.5

What goes into a cell during Cellular respiration? Give me a simple answer, I'm in 6th grade!
Answer:
Oxygen and glucose.
Explanation:
Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage.
Additionally, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.
Basically, oxygen goes into the body of a living organism such as plants, humans and animals when they breathe while glucose is absorbed by the body when they eat.
Hence, oxygen and glucose goes into a cell during Cellular respiration and as such are known as the reactants.
