what property of water makes water so helpful in riding the body of wastes?
A) Water is versatile solvent.
B) Water is expands upon freezing
C) Water cohesive forces surface tension upon its surface
D) Water has a high specific heat.
Answer:
A) Water is versatile solvent.
Explanation:
Water is a chemical compound consisting of one atom of oxygen (O) bonded chemically to two atoms of hydrogen (H). It is a unique substance due to its properties. Water is a polar molecule i.e. has both positively and negatively charged ends, hence, making one of its properties of being a UNIVERSAL SOLVENT possible.
Water is said to be a universal solvent because it can dissolve more solid substances than any other liquid. This outstanding property of water is key to its function in getting rid of wastes because these wastes readily dissolve in water and are transported or carried to sites of exit from the body. For example, urea is a waste in humans, which gets dissolved in water to form URINE that is excreted.

7. Which of the following processes DOES NOT produce new genetic combinations?
crossing over during meiosis
b. fertilization in sexually-reproducing organisms
c. independent assortment in gamete production
d. replication of DNA in mitosis
Replication of DNA in mitosis does not produce new genetic combinations. The correct option is d.
In mitosis, DNA replication does not result in novel genetic combinations. Somatic cells go through a process called mitosis, which produces two identical daughter cells with the same genetic makeup as the parent cell.
The DNA is properly duplicated during mitosis while keeping the same genetic sequence. Therefore, during this procedure, no new genetic combinations or variants are introduced.
The other processes, including crossing over during meiosis, fertilisation in sexually reproducing organisms, and independent assortment in gamete formation, all help to produce novel genetic combinations by recombining genetic material.
Thus, the correct option is d.

Explanation:
A group of students placed small objects in a ripple tank and observed
the path of the water waves as they approached the obstacles. They
observed the waves bending around the objects. This phenomenon can
be observed in a harbor as waves bend around small boats. In order for
this to occur, the wavelength of the waves must be larger than the
objects they encounter.

¿Qué efecto tiene para las cadenas tróficas la tala y deforestación de los organismos productores?
Answer:
tiene un efecto devastador sobre las cadena tróficas de ecosistemas terrestres
Explanation:
En una cadena trófica, los organismos productores, también conocidos como autótrofos, son aquellos capaces de convertir la energía proveniente del Sol (organismos fotosintéticos) o de la oxidaxión de compuestos inorgánicos (organismos quimiosintéticos) en nutrientes a través de la formación de enlaces de carbono que componen moléculas orgánicas tales como, por ejemplo, carbohidratos (es decir, celulosa, azúcar, etc). Por ejemplo, los árboles son organismos productores que usan la fotosíntesis para convertir la energía lumínica solar en energía química la cual es utlilizada por consumidores primarios (hervívoros) de la cadena trófica. Los árboles son organismos productores los cuales juegan un papel clave en ecosistemas terrestres, representando la principal fuente de alimento y nutrientes para diferentes consumidores primarios. Además, estos organismos autótrofos son también fundamentales porque generan oxígeno (O2) y capturan el dióxido de carbono (CO2) de la atmósfera, lo cual es un proceso clave para el sostenimiento de la vida en la tierra.

Cancer is a disease related to the cell life span and cell division. If cancer cells were added to the data table, predict what would be written under the columns headed “Life Span” and “Cell Division.” Explain the reasoning underlying your predictions.
Many people live much longer than 5 years after their cancer diagnosis. The term does not mean a person will only survive for 5 years.
For example, 90% of people with breast cancer will be alive 5 years after the diagnosis of cancer.
Cell Division:Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.
Cancer is a disease caused when cells divide uncontrollably and spread into surrounding tissues.

what causes the movement of wind and water to the right or left on Earth?
Answer:
The Coriolis effect describes how Earth's rotation steers winds and surface ocean currents. Unlike land, air and water move freely (in the absence of obstacles). The Coriolis effect causes the path of a freely moving object to appear to curve. This is because Earth is rotating beneath the object.

Identify the correct amino acid sequence for the mRNA strand ACG using the codon chart below.
Threonie
Serine
Lysine
Arginine
Answer:
option 4 is your answer
Explanation:
The correct amino acid for the ACG sequence is Threonine (Thr).
During translation, a messenger RNA (mRNA) sequence is read in the ribosomes to synthesize a polypeptide chain (i.e., a protein).
The correct order of triplets of nucleotides or 'codons' in the mRNA determines the order of amino acids in the nascent polypeptide chain.
Each codon determines a specific amino acid. In this case, the codon ACG encodes for the amino acid Threonine.
In conclusion, the correct amino acid for the ACG sequence is Threonine (Thr).

Rohit read an interesting fact that if diffusion were to move oxygen in our body, it is estimated that it would take 3 years for a molecule of oxygen to reach our toes from our lungs. Then what is the reason that it travels so fast?
Answer:
See the answer below
Explanation:
Oxygen moves fast around the human body due to the fact that there is a transportation system for it. The blood serves as the transporting medium for oxygen. Haemoglobin in the red blood cells picks up the oxygen and delivers them to places where they are needed in the body.
If an organism had 20 chromosomes, how many chromosomes would the daughter cell have after mitosis? After meiosis?
Answer:
After mitosis, the daughter cell has 20 chromosomes and after meiosis, the daughter cell has 10 chromosomes.
So the answer is 20 and 10
Answer:
[tex]\boxed {\boxed {\sf Mitosis: 20 \ chromosomes}}[/tex]
[tex]\boxed {\boxed {\sf Meiosis: 10 \ chromosomes}}[/tex]
Explanation:
Mitosis and meiosis are both types of cell divisions, but they are different.
Mitosis
1 cell division that results in 2 daughter cells used for growth, repair, and developmentThe cells are genetically identical with the same number of chromosomes as the parent cell.Meiosis
2 cell divisions resulting in 4 daughter cells for sexual reproduction The cells are genetically different and have half the number of chromosomes as the parent.The organism has 20 chromosomes.
Mitosis: same number of chromosomes=20 Meiosis: half the chromosomes= 20/2= 10After mitosis, the daughter cell has 20 chromosomes. After meiosis, the cell has 10.
What is the correct order to make a protein?
Answer:
The correct sequence of events in protein synthesis is transcription, then translation.
The correct order to make a protein is DNA >> RNA >> protein.
During gene transcription, a specific fragment of DNA (i.e., a gene) is used as a template to create a complementary RNA molecule known as a messenger RNA molecule.
Subsequently, this messenger RNA is then used as a template to create a polypeptide chain (i.e., a protein) in the ribosomes by a process called translation.
In conclusion, the correct order to make a protein is DNA >> RNA >> protein.
