What is the wavelength of an X-ray whose frequency is 2.0 × 1018 Hz? Hint: An X-ray is an electromagnetic wave, so its velocity is equal to the speed of light (3.0 × 108 m/s).
A.
1.5 × 10-10 m
B.
3.0 × 10-8 m
C.
6.0 × 10-9 m
D.
0.6 × 10-11 m
Answer:
A. 1.5 × 10-10 m
Explanation:
Given the following data;
Frequency = 2.0 × 10^18 Hertz.
Speed of light = 3.0 × 10^8 m/s
To find the wavelength;
Wavelength = speed/frequency
Substituting into the equation, we have;
Wavelength = 3.0 × 10^8/2.0 × 10^18
Wavelength = 1.5 × 10-10 meters.

Sequence of dna that is not involved in coding for a protein
Answer:
Transfer RNA, Ribosomal RNA, and Regulatory RNAs
Explanation:
Non-coding DNA sequences are components of an organism's DNA that do not encode protein sequences. Some non-coding DNA is transcribed into functional non-coding RNA molecules.
Answer: Ribosomal RNA, Transfer RNA, and Regulatory RNAs.
Explanation: The introns do not code for any protein and are removed from the mRNA before it is made into protein.

There are so many microbes in a single mL of culture, it is very difficult to perform one dilution to produce countable cells. Microbiologists need to perform a dilution series, where multiple dilutions are performed in sequence to arrive at the correct dilution. Dilutions are cumulative. Multiply the series of dilutions together to find the final dilution value. If 6 serial dilutions are performed, each with a dilution of 0.1, what is the cumulative dilution
Answer:
cumulative dilution = 0.000001
Explanation:
A serial dilution is a stepwise kind of dilution repeated a certain number of times, in which the concentration reduces exponentially each time.
The cumulative dilution is the final dilution gotten depending on the number of times dilution has been done and the dilution factor. The formula is given as:
Cumulative dilution = (F)ⁿ
where:
F = dilution factor = 0.1
n = number of serial dilutions = 6
∴ cumulative dilution = (0.1)⁶ = 0.000001
leaves of cactus are modified into thorns
Answer:
To reduce loss of water through transpiration leaves of cactus plants are modified into spines.
Explanation:
Answer:
leaves are reduced to spines in a cactus , so that the water does not get evaporated with the heat of the SUN. 1. They are present in hot deserts which are scarce in water so in order to reduce the loss of water by Transpiration from the surface of the leaves, its leaves are reduced to spines

In a population of 239 pea plants in equilibrium, 47 individuals have white petals, while the rest have purple petals. Color is controlled by a single gene with two alleles. Purple is dominant to white. How many individuals in the population should be heterozygotes if the population is in Hardy-Weinberg equilibrium
Answer:
The number of heterozygous individuals in this population is 120.

Why do many plants have specialized cells that produce strong odors?
A. To attract prey
B. To scare off predators
C. To attract insects
D. To collect more sunlight
SUBMIT
Answer:
c
Explanation:
some plants use this as a way so they could pure insect to trap them and digest them
Plants have specialized cells that produce strong odors to attract insects.
Example:- The inflorescence of the titan arum plant attracts specific pollinators by emitting an intense, carrion‑like odor.Why plants attract insects?Flowering plants attract pollinating insects with scent from their flowers and bright colors. If they have become infested with herbivores like caterpillars, they attract beneficial insects like parasitic wasps with the help of scent signals from their leaves.Flowers attract insect for pollination too.

How is cellular respiration and photosynthesis linked to specific organelles within the eukaryotic cells?
Answer:
Respiration. The energy collected in the chloroplasts is used during cellular respiration. ... The carbon dioxide and water produced are transferred back to the chloroplast where they are again used for photosynthesis. Cellular respiration takes place in another organelle called the mitochondria.
Explanation:
The mitochondria and cytoplasm is responsible for cellular respiration and the chloroplast is responsible for pjotosynthesis. Scientists theorize that mitochondria were once bateria themselves since they have their own Dna. They incorporated themselves into our cells to help us make energy. The chloroplast uses sunlight to break the hydrogen off the water and use the hydrogen to transfer electrons.

?Which form of energy is NOT correctly associated with the related example
kinetic energy: fat molecules O
potential energy: water held behind a dam o
kinetic energy: movement of muscles
chemical energy: glucose o
Answer:
kinetic energy: fat molecules
Explanation:
Fats store energy so it would be potential.
Kinetic energy: fat molecules
Kinetic energy is the energy that an object or particle uses during its motion. Potential energy is the stored form of energy already present in the object or particle. Chemical energy is the energy stored in the bonds of chemical substances. Water held behind the dam will have potential energy the water currents store energy within them which can be used to move the turbine in the water dam to produce electrical energy. Movement of muscles during walking, running, or performing any other activity which can be seen in the form of displacement from one region to another is due to kinetic energy. Glucose is a chemical molecule whose bonds when broken releases energy in the form of ATP or adenosine triphosphate which is a chemical energy. Fat molecules store energy in the adipocytes in the form of potential energy not kinetic energy. Hence, option kinetic energy: fat molecule is incorrect.Learn more about kinetic energy:
