Can blood cells replicate themselves?
Answers
Answer:
Blood cells cannot replicate themselves.
Explanation:
They do not replicate like other bodily cells because they cannot independently process and create proteins. Blood cells are instead formed in the bone marrow of bones. Depending on whether it is RBC or WBC, there are different types of bone marrow for producing that type of blood cell.
Find out two types of water purification and name and describe them here.
Answers
Answer:
1. Reverse Osmosis
Reverse Osmosis works by forcing feedwater through a semi-permeable membrane.
A pump is used to apply pressure to reverse the normal osmotic flow across a membrane, meaning purified water molecules (permeate) are forced through the reverse osmosis membrane and recovered in preference to contaminants in the concentrated side which are left behind (reject concentrate).
2. Oxidisation
Oxidisation in the form of chlorination has been used as a means of water purification since the beginning of the last century. Hypochlorite is the key agent, achieving a disinfection of water by oxidising bacteria to eliminate waterborne diseases. Several different methods can be used to provide oxidation, including ozonation, chloramination, UV, bromination & chlorine dioxide. During the treatment, hydroxyl radicals are generated to destroy bacteria cells.
In a DNA strand, you find that 20% of the bases are Adenine. What percentage of the DNA would be Cytosine?
Answers
Answer:
Yes
Explanation:Since adenine is 20%, then thymine is 20% as well. The total of both is 40%. From 100 remains 60% which is divided equally between guanine and cytosine, so each is 30%.

Why do offsprings look different from there parents?
Answers
Living things produce offspring of the same species, but in many cases offspring are not identical with each other or with their parents. Plants and animals, including humans, resemble their parents in many features because information is passed from one generation to the next.
Genes come in different varieties, called alleles. Somatic cells contain two alleles for every gene.
What is the energy source for producers, consumers, and decomposers?
Answers
Answer:
The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers such as plants, algae, and cyanobacteria use the energy from sunlight to make organic matter from carbon dioxide and water. This establishes the beginning of energy flow through almost all food webs.

What is an example of a codominate
phenotype?
Answers
Answer:
With a codominant trait, phenotypes like fur color are combined. For example, if a black-feathered chicken breeds with a white-feathered chicken, their offspring will be both black and white. They will not be gray; rather, there will be spots of both colors. Codominance means that neither allele can mask the expression of the other allele. An example in humans would be the ABO blood group, where alleles A and alleles B are both expressed. So if an individual inherits allele A from their mother and allele B from their father, they have blood type AB.

Briefly describe the layers of the atmosphere:Troposphere-Exosphere-Stratosphere-Mesosphere-Thermosphere-
Answers
Answer:
Explanation:
-Troposphere. It is the lowest layer and encompasses the Earth's surface up to an average height of 12 kilometers; about 17 kilometers in the equatorial regions and about 9 kilometers at poles
- Stratosphere.Separated from the troposphere by the tropopause is this layer containing 19 percent of the atmospheric gases, but very little amount of water vapour.
-Mesosphere. It is located above the stratosphere up to a height of 80-85 kilometers in the mid-latitudes, where the mesopause is located.
-Thermosphere. From the upper limit of the mesopause extends the thermosphere, known as the upper atmosphere.
-Exosfera. It is the last layer, the outerest until connected with the solar wind.

Which statement is TRUE?
1)Light waves always travel at a constant speed, but sound waves do not.
2)Waves travel at different speeds through different materials.
3)Wave speed depends on the amplitude of the wave.
4)Light waves and sound waves travel at the same constant speed.
Answers
Answer:
C. Is correct
Explanation:
For a sound wave it depends on how much compression the loud speaker or musical instrument creates. In other words, it depends on the energy the source put into the wave. It does not depend on frequency, wavelength, or velocity.
The correct answer is option 3 as it explains Wave speed depends on the amplitude of the wave.
In the case of sound waves, it depends on how much compression the speaker or instrument produces. In other words, it depends on the energy the source puts into the wave. It does not depend on frequency, wavelength, or speed.
Wave amplitude does not affect the speed at which the wave propagates. Wave velocity depends on both wavelength and wave frequency. Most wave velocities depend on the medium or substance through which the wave passes. Sound waves travel faster in air and water than in solids and gases.
What is wave amplitude?Amplitude, in physics, is the maximum displacement or distance that a vibrating object or point on a wave has moved, measured from an equilibrium position. This corresponds to half the length of the vibration path.
Hence it concludes that Wave speed depends on the amplitude of the wave.

Explanation:
other 2/4 will be carrier(Ss) and other 1/4 will have both dominant trait (SS)
Answer:
B. 1/2
Explanation:
The genotypes of the parents are Ss and Ss. We know this because Heterozygous basically means different alleles. The punnet square of this problem will show that the possible genes given to the offspring are SS (capital letters mean dominant. keep in mind that sickle-cell anemia is a recessive trait, meaning it is written in lowercase), Ss, Ss, or ss. So this means the offspring will have a 1/2 chance of becoming heterozygous (Ss).
