A red Corvette is traveling down Broad St. At 45mph. The speeld limit is 25 mph. The car is captured on camera speeding, how many miles per hour was the car traveling over the speed limit?
Answer:
The answer is 20 mph
Explanation:
This question is more technical than it is of actual calculation. The car was travelling at a speed of 45 miles per hour when the actual speed limit that should be observed is 25 miles per hour. His excess speed can be calculated as
45 mph - 25 mph = 20 mph
Thus, the car was travelling at a speed of 20 mph more than the actual speed limit of the road which is 25 mph
What happens to biodiversity
and ecosystems when the
environment changes?
the ball is pushed so it begins to roll down the hill . it now has _______
A) kinetic energy
B) a rest position
C) more potential
D) no energy
Hi there!
[tex]\large\boxed{\text{A) Kinetic Energy}}[/tex]
When an object begins at rest but a force acts upon it to cause it to be in motion, energy transfer occurs.
In this instance, the ball was initially at rest, so it had potential energy. Once the ball begins is in motion, however, the potential energy is converted into Kinetic Energy.
3 reasons why bringing back extinct animals would help preserve the planet
Answer:
3 reasons why to bring back extinct animals would help preserve the earth is:
1.) Revived species could also assist conservation by acting as a “flagship species”.
2.) People may be excited to see a formerly extinct species, and are more willing to engage in conservation.
3.) At the same time, extinct species could also reinforce the preservation and protection of natural habitats.

DNA replication results in two separate DNA molecules. How are the DNA molecules at the end of the process related to the DNA molecule at the beginning of the process.
The DNA double helix. Helices open as hydrogen bonds disintegrate. The creation of a new, complementary strand uses the template provided by each DNA strand.
What is the regulation of DNA replication process?A new and an old chain of nucleotides is combined to form two DNA molecules as a result of DNA replication.
Because half of the chain is made up of the original DNA molecule and half is new, DNA replication is referred to be semi-conservative.
With one new and one old strand in each, replication creates two identical DNA double helices.
The production of a primer, a brief section of RNA that serves as the beginning point for the synthesis of fresh DNA, follows.
Therefore,DNA helicases unwind DNA during DNA replication at locations known as origins where synthesis will begin.

Hypothesize what the results would be if a large cell managed to divide, despite the fact that it had grown beyond an optimum size
Answer:
Hypothesize what the result would be if a large cell managed to divide, despite the fact that it had grown beyond an optimum size. The resulting cells could not sustain themselves if the plasma membrane to cell contents (SA to Volume) ratio was too small a difference.
Explanation:
It is likely that the resulting daughter cells would be smaller than normal and may not function properly, potentially leading to impaired growth or viability of the organism.
What happens when cells divide after growing beyond an optimum size?If a large cell managed to divide despite the fact that it had grown beyond an optimum size, it is likely that the resulting daughter cells would be abnormal in size or function. Cells that are larger than the normal range for their type tend to have problems with DNA synthesis and cell division. The DNA may not be accurately replicated, leading to genetic errors and abnormal gene expression. The cell division process may also be impaired, resulting in cells that are larger or smaller than normal.
The consequences of these abnormalities could be serious and potentially harmful to the organism. Abnormal cells may be unable to perform their normal functions, leading to deficiencies or malfunctions in the tissues or organs where they are located. In extreme cases, abnormal cells may become cancerous and contribute to the development of tumors. For these reasons, it is important for cells to divide when they are at an optimal size, in order to ensure that the daughter cells are healthy and functional.

Where does the energy come from that makes the movement of air and water possible?
Answer: Solar energy
Explanation:
The water and wind cycle is driven by the solar energy. The solar energy evaporates the water from the water bodies like oceans, rivers, lakes, and ponds and from other sources of water.
The earth's surface absorbs the heat radiations from the solar energy and the air above the earth's surface get hotter due to absorption of heat.

What role do enzymes play in the chemical reactions of living organisms?
Answer:
Enzymes are proteins that act as biological catalysts. They speed up chemical reactions that take place in cells. Enzymes act by lowering the activation energies, which has a dramatic effect on how quickly reactions completed.
Explanation:
basically they lower the activation energy and increase the rate of chemical reactions.
What is the genetic code of the Reading strand
Answer:
DNA
Explanation:
The genetic code reads DNA sequences in groups of three base pairs, which means that a double-stranded DNA molecule can read in any of six possible reading frames--three in the forward direction and three in the reverse. A long open reading frame is likely part of a gene.
The genetic code (genome) of the reading strand is ATGACG, The DNA sequence is read in the 5′-3′ direction. Genes or other sites can be positioned upstream (towards the 5′ ends) or downstream (towards the 3′ ends) on a DNA strand.
What is genetic code?A double-stranded molecule that makes up the majority of chromosomes and holds the genetic code is DNA, sometimes referred to as deoxyribonucleic acid.
The nucleotides of DNA or RNA are arranged in the genetic code. Codons are made up of three-base groups and each one represents an amino acid (or start or stop).
Once a stop codon is reached, the codons are read in order starting with the start codon. Universal, clear-cut, and redundant describe the genetic code.
Therefore, the genetic code (genome) of the reading strand is ATGACG.

What might an elevated skin temperature indicate beside a fever from a cold, flu, or other typical viral disease? How might you test for an elevated temperature?
Answer: Fever is a common symptom of illness. The Centers for Disease Control and Prevention (CDC) defines fever as a temperature above 100.4° F, though children often run higher fevers than adults.
Many types of infection can cause fever, as your body will increase temperature to effectively fight off the virus or bacteria causing the infection. These fevers will usually resolve themselves as your body works to get rid of the foreign invader.
Explanation:
Fever is one of the common symptoms of different illnesses and is also a defense mechanism of the body. A temperature above 100.4° F is considered as fever.
Fever can be caused due to:
1. The rise in the skin temperature is generally due to the infection from bacteria or viruses that can result in the flu, cold, or certain viral diseases. The fever can be an indication of any infection or inflammation in any part of the body.
2. The activities like exercising can also lead to an increase the body temperature. The contraction of muscles releases 20% energy and the rest 80% is converted into heat energy. The heat is then circulated to different parts of the body, causing an increase in the temperature.
3. The rise in the temperature can be measured by the thermometer. It is a device that measures body temperature either digitally or traditionally.
Thus, the cause of fever can be a defense mechanism, exercise, and infection from the pathogen.

Answer:
The ratio will be 3:1
Explanation:
edge 2020
The ratio of the purple to white flowers produced from a cross between two heterozygous purple flowers will be 3:1. Thus, the correct option will be A.
What is a Genetic cross?A genetic cross is the deliberate breeding of two different individuals which results in the production of offspring that carry part of the genetic material from each of the two parents. The parent organisms must be genetically compatible to each other and may also be from different varieties or two closely related species.
Genetic cross diagrams are made using Punnett squares that show how likely the offspring are to inherit the characteristics from both of their parents.
In the given condition, two heterozygous purple flower parents are crossed. Here, the purple flower color is dominant over white flower color and from this cross, the organisms produced in 3:1 ratio with three purple flower plants and one white flower plant.
Therefore, the correct option will be A.
