Answer:
B. The rating number means it will protect you that many times longer than without sunscreen
Explanation:
The sun protection factor is a comparison between the length of time it will take for a skin that has no sunscreen to begin reddening compared to a skin with sunscreen applied. Therefore, the ratings is an indication of the length of time a person will be protected from ultraviolet rays than when the individual has no sunscreen applied.
While higher SPF's are believed to offer more protection against UV rays, the added protection is usually just a negligible amount. They are very important for the skin and protect the body against diseases like cancer.
how are electromagnetic waves and mechanical waves the same?
bots get mass reported, no bad answers bad answers get reported, you get brainlyest if you answer first
Answer:
Both electromagnetic and mechanical waves are the movement of energy. They can be measured in the same ways too. The amplitude, frequency, and wavelength are ways to represent the measurements of waves. Additionally, they both have crests and troughs. Finally, both can be reflected, absorbed, or transmitted.

The offspring in binary fission are
identical
different
Answer:
Identical
Explanation:
Binary fission is a form of asexual reproduction. This is when only one parent is involved in creating offspring. Since there is only one parent, two sets of DNA cannot be combined into a new offspring; so, it must be identical.
How does the energy produced by the sun travel to Earth?
o A. by the convection of heat through particles in space
B. by the magnetic fields between the sun and Earth
0 C. by the radiation of electromagnetic waves through space
D. by the process of conduction of heat between the sun and Earth
Explanation:
Energy is radiated from the sun, through the vacuum of space at the speed of light. When this energy arrives at Earth, some of it is transferred to the gases in our atmosphere.
HELP I GIVE BRAINLEST Which of the following is true about an
estuary?
It is all fresh water.
It is all salty water.
It has very few organisms.
It is affected by tides.
Answer:
The last one since estuaries are highly affected and are dependent on tides
Answer:
all fresh
Explanation:
Some factories have started using large tanks of bacteria to remove carbon dioxide from the atmosphere. As more factories start to do this, the amount of carbon dioxide in the atmosphere could decrease over time. If this happens, and if energy coming from the sun and the amount of carbon dioxide being put into the atmosphere otherwise stay the same, what would happen to the total amount of energy in the Earth system and to global average temperature
Answer:
The carbon dioxide in the atmosphere will be reduced if more factories started using bacteria to capture carbon dioxide
Explanation:
There will be more that will reach the Earth System than exited as combustion introduced carbon dioxide to the atmosphere, so the total amount of energy in the system will increase.

what is the geological carbon cycle
Answer:
Geologic carbon sequestration is the process of storing carbon dioxide (CO2) in underground geologic formations. The CO2 is usually pressurized until it becomes a liquid, and then it is injected into porous rock formations in geologic basins.

In humans Attached earlobes (A) is dominant to unattached earlobes (a). Write all three possible genotypes and phenotypes below.
Answer: genotype Aa AA aa
Phenotype unattached earlobes, attached ear lobes
Explanation: genotype will be the combination of the genes. you have dominant (AA) recessive (aa) and heterozygous (Aa) the phenotype will be the expression from the genotype so for both dominant and heterozygous the phenotype is attached earlobes and for recessive the phenotype is unattached earlobes

Case summary
Diagnosis
Using Anthony's symptoms and initial lab results, describe how you diagnosed that the
problem was kidney failure.
Treatment Goals
Describe the treatment goals for dialysis.
Answer:
Through symptoms.
Explanation:
We diagnosed the problem was a kidney failure due to the decreased urine output , swelling in your legs, ankles or feet, shortness of breath, fatigue, confusion, Nausea and Weakness. The main symptom is the swelling in legs, ankles or feet that tells about kidney failure. The treatment goal of Hemodialysis is to filter waste products and water from your blood. I works just like the kidneys. This treatment is used when the kidney fails to filter waste materials inside the body.
Usually for the initial diagnosis of possible renal failure, there are complaints of pain in the lower back and little urine.
What is dialysis and how does it work?Hemodialysis is the procedure by which a machine filters and cleans blood, doing some of the work that the diseased kidney cannot do. The procedure removes harmful waste from the body, such as excess salt and fluids.
Among the tests that make the diagnosis of acute renal failure are:Measurements of urine outputUrine testsBloodtestsImaging tests, such as ultrasound and CT scanRemoval of a kidney tissue sample for testing (biopsy).With this information, we can conclude that normally for the initial diagnosis of possible renal failure, there are complaints of pain in the lower back and little urine.

Why do asexually reproducing organisms not benefit from recombination? Explain.
Answer:
Explanation:
While asexual reproduction only involves one organism, sexual reproduction requires both a male and a female. Some plants and unicellular organisms reproduce asexually. Most mammals and fish use sexual reproduction. Some organisms like corals and komodo dragons can reproduce either sexually or asexually. But in the long term (over several generations), lack of sexual reproduction compromises their ability to adapt to the environment because they do not benefit from the genetic variation introduced by sexual reproduction.The key difference between sexual and asexual reproduction is that sexual reproduction involves two parents of the opposite sex while asexual reproduction involves a single parent.
The ability to reproduce and produce a new generation of the same species is one of the fundamental characteristics of a living organism. It involves the transmission of the genetic material from the parental generation to the offspring generation, ensuring the characteristics of the species and perpetuating the characteristics of parental organisms. Before a new individual reaches its own reproductive stage, it normally has to go through a period of growth and development. Some members of the species will die before they reach reproductive age due to predation, disease and accidental death. So the remaining species will only able to produce more offspring and contribute to the continuation of the species. There are two basic types of reproduction; namely, asexual and sexual reproduction.
Answer:
Recombination only occurs when 1/2 of the strand from each parent is used, in which parts of the strand may be used to create the new strand. Asexually reproducing organisms don't benefit rom recombination, because frankly there is no other strand in which recombination can be used. Instead, the most the recombination can occur is within it's own strand, which means that essentially there is less combinations then if two strands are used. As such, asexually reproducing organisms would look more or less the same.

What type of organisms do scientist usually agree that birds are descended from?
A) reptiles
B) fish
C) amphibians
D) mammals
Answer:
A) reptiles
Explanation:
Many scientists are convinced that birds evolved from dinosaurs. Numerous finds in recent years have seemed to support the hypothesis that birds descended from two-legged, running dinosaurs called theropods. So, theropods are reptiles and the correct answer is reptiles.
During the process shown above, the two strands of one DNA molecule are unwound. Then, DNA polymerases add complementary nucleotides to each strand which results in the formation of two identical DNA molecules.
\
Answer:
This question is incomplete as it lacks image, however, it can be answered based on the description. The complete part of the question is:
" This process is known as dna _______. A.) transcription B.) translation C.) cloning D.) replication
The answer is D. replication
Explanation:
DNA replication is the process whereby a DNA molecule is duplicated to form to identical copies of itself. The process of DNA replication is very pivotal and must occur prior to any cell division.
This process follows the semi-conservative model in which the double-stranded DNA molecule unwounds into two separate single strands. The single strands are then used as template for the synthesis of another complementary strands by DNA polymerase enzyme. At the end, the two DNA molecules are identical in base sequence.
