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.

Describe how the genetic code found in DNA bases is used to synthesize a polypeptide chain.
Answer:
The genome of an organism is inscribed in DNA, or in some viruses RNA. The portion of the genome that codes for a protein or an RNA is referred to as a gene. Those genes that code for proteins are composed of tri-nucleotide units called codons, each coding for a single amino acid.

What are some advantages of asexual reproduction when compared to sexual reproduction? (In your own words please for brainliest!!)
Answer And Explanation:
The advantages of asexual reproduction compared to sexual reproduction include the population being able to increase rapidly when the conditions are in their favour, only one parent is needed, it is more time and energy-efficient due to not needing a mate and it is faster than sexual reproduction.

Which of the following is an example of a physical variable of water quality *
Answer: Physical properties of water quality include temperature and turbidity. While chemical characteristics involve parameters such as pH and dissolved oxygen. These parameters are relevant not only to surface water studies of the ocean, lakes and rivers, but to groundwater and industrial processes as well.
I hope this is the answer if not I apologize :P
Answer:
One of the physical variables that affect the properties of water is temperature
Explanation:
I assume that by physical properties you mean external factors that affect the properties of the water correct? well depending on the temperature of the air that the water is exposed to the war can shift from either a liquid to a solid if it if the air is cold or it can change from a liquid to a gas when the air is hot. I'll explain how this works when the temperature of the air is hot the water will under go an exo thermic reaction (A reaction that causes things to emit heat and become hot) and because water boils at a certain point as the water gets hotter and hotter it will evaporate into mist. If the air around the water is cold then it produces an endothermic reaction which will cause the ice to get colder and colder as time goes on until it transitions from being a liquid to a solid in the form of ice. Hope this helps:)

Explanation:
which two body systems interact to expel the waste product carbon dioxide
a urinary system
b nervous system
c excretory system
d circulatory system
Answer:
excretory system and circulatory system
Explanation:
Blood is part of circulatory system and as it move through various organs it exchanges the gases i.e give oxygen to the cell and take carbon dioxide from them. After taking CO2, the blood becomes impure and hence it passes through the kidney before going to the heart. Kidney is part of excretory system which removes carbon dioxide from blood and thus purifies it.
Scientist observed an organism X and noted down the mode of nutrition as follows X secretes enzymes outside its body and digests food with these enzymes. It then absorbs the digested food. Which organism was observed by the scientist?
Answer:
Hydra
Explanation:
The mode of nutrition being described in this question is EXTRACELLULAR DIGESTION, in which a food substance is chemically broken down externally. The organisms being portrayed is HYDRA. Hydra is an animal that secretes digestive enzymes that work on the food extracellularly (outside the organism), then absorb the digested food.
Therefore, the organism X observed by the scientist whose mode of nutrition is to secrete enzymes outside its body and digests food with these enzymes, then absorbs the digested food is the HYDRA.

How does the process of gel electrophoresis produce DNA fingerprints? An electric current sorts DNA nucleotides according to their bases. O An electric current cuts a DNA strand into segments of various lengths O An electric current causes segments of DNA to move at different rates O An electric current supplies a charge to uncharged segments of DNA
Answer:
Gel electrophoresis
Explanation:
Gel electrophoresis is a technique used to separate DNA fragments according to their size. DNA samples are loaded into wells (indentations) at one end of a gel, and an electric current is applied to pull them through the gel. DNA fragments are negatively charged, so they move towards the positive electrode.

2. When calculating the recombinant frequency of two genes, what is
the most important factor?
O A. how close they are to each other
OB. how close they are to the end of the chromosome
Oc. whether they are on the X or Y chromosome
OD. which one is higher on the chromosome
Answer:
A
Explanation:
The most important factor is how close they are to each other.
• The physical swapping of the pieces of chromosomes at the time of meiosis is responsible for the recombination of genes.
• The swapping can take place anywhere along the length of the chromosome, that is, in any part of the gene.
• The recombination frequency between the two genes is equivalent to the ratio of offspring in which the event of recombination took place between the two genes at the time of meiosis.
• The determination of the recombination frequency is done by the frequency of the recombination events between the two genes in meiosis.
• The more the physical distance between the two genes, the more is the probability that the recombination take place during any meiosis event.
Thus, the correct answer is option A.
