Thus, water absorbs or releases a great deal of_______ , helping to moderate temperatures. Because_______ is less dense than liquid water, it floats and protects lakes and oceans from freezing solid. Water is a versatile . Blood and other biological fluids are aqueous solutions with a diversity of dissolved .
Answer:
The correct words that film in the blanks are;
Polarity
Cohesion
Hydrogen bonds
Heat
Ice
Solvent
Solutes
Explanation:
Water is a highly polar molecule. Its polarity allows it to form strong intermolecular hydrogen bonds which accounts for the forces of cohesion in the water.
The hydrogen bonds form and break with evolution of heat hence accounting for the role of water in temperature regulation.
Ice is less dense than water due to spaces in the solid. Water is regarded as a universal solvent for polar solutes. Blood and other aqueous body clouds usually contains many dissolved solutes.

1. cross-breeding; a method that unionizes gametes of differing genes to create a new individual
recombinant DNA
2. cultured DNA molecules from different biological sources
hybridization
3. a process of breeding organisms because of their specific traits
selective breeding
Answer:
Hybridization - a method that unionizes gametes of differing genes to create a new individual
Recombinant DNA - cultured DNA molecules from different biological sources
Selective breeding - a process of breeding organisms because of their specific traits
Explanation:
In biology, hybridization is the process of creating a hybrid by combining gametes of different species or varieties. An example of a hybrid is a liger - an offspring of a lion and a tiger.
Recombinant DNA is DNA created in the process of genetic recombination. Genetic material from multiple sources is combined, creating sequences that do not occur in the genome naturally.
Selective breeding is the process of breeding organisms with desirable characteristics. For example, a good dog breeder will breed only two completely healthy dogs in order to make sure that the puppies don't have any health issues often associated with the breed.

How might the digestive system and the immune system interact to help protect the body?
Please i need a correct and accurate answer. ++ giving brainliest
Answer:
Around 70% of our immune system dwells in our digestive tract in the form of gut-associated lymphoid tissue (GALT). An important component of our immune system called plasma cells (which give rise to invader-defending antibodies) also reside within the GALT. Our gut is the major channel between the external environment and the internal systems of our body. It is exposed to plenty of germs and harmful invaders such as bacteria and viruses present in food particles on a daily basis. [1] These toxic agents are perceived by the immune system in the gut as being harmful to our body and attacked. That being said, our body does not reject everything we put into it. This process is known as tolerance. When our immune system rejects an otherwise harmless substance, we are labeled as being sensitive or allergic to that food/food ingredient.

After a workout, the muscles in a basketball player's legs are very sore. Which of the following statements best explains why the basketball player experiences this muscle soreness after a workout?How are the processes of photosynthesis and cellular respiration interrelated?
Answer:
1. There is an increase in the amount of lactic acid being produced in the muscle cells during the process of anaerobic respiration.
2. Photosynthesis removes carbon dioxide from the atmosphere and cellular respiration releases carbon dioxide into the atmosphere
Explanation:
Note, medical professionals consider lactic acid a byproduct released when we are engaged in intense physical exercise. Although it is still believed that the increase in the number of lactic acids causes muscle soreness, some medical findings have revealed they have no such effect on muscles.
Put simply, photosynthesis involves a natural cycle where carbon dioxide is released into the atmosphere by humans and animals for plants, and green plants undergo a process where they convert carbon dioxide into oxygen for humans. It is interrelated with cellular respiration in the sense that, cellular respiration also involves a convertion (of glucose) to carbon dioxide released into the atmosphere.

Explanation:
Chloroplasts are double membrane organelles with a smooth outer membrane and an inner membrane that is folded into disc-shaped sacs called the thylakoid. Thylakoids contain chlorophyll and other pigments (red, orange, yellow, brown) and are found in stacks
called granum (grana, plural.)
This organelle is used to:
A. perform the process of cellular respiration.
B. expell O2.
C. create ATP.
D. covert solar energy into chemical energy.
Answer:
D. convert solar energy into chemical energy.
Explanation:
Chloroplasts are the organelles that carry out photosynthesis. They contain chlorophyll, which traps light energy from sunlight to power chemical reactions that produce glucose.
The solar energy is converted into chemical energy, which is used to synthesise glucose, along with carbon dioxide and water. The reactions produce glucose and release oxygen as a byproduct.

Explanation:
Krusty was told that a certain itching powder was the newest best thing on the market; it even claims to cause 50 % longer lasting itches. Interested in this product, he buys the itching powder and compares it to his usual produce. One test subject (A) is sprinkled with the original itching powder, and another test subject (B) is sprinkled with the Experimental itching power. Subject A reported having itches for 30 minutes, Subject B reported to have itches for 10 hours.
Hi, you've asked an incomplete question. The full question reads;
1. Identify the:
Control GroupIndependent VariableDependent Variable2. Explain whether the data supports the advertisement's claims about its product.
Answer:
Subject AThe "certain itch powder"The time of itchinessExplanation:
1. Remember, the Control group in research often refers to the group in a research experiment that who are not subjected to any treatment, rather they are used as a comparison scale to see how other tested subjects perform.
We also need to note here that the independent variable here refers to a variable or factor that does not change (ie it is independent), but which results in changes in other variables. From the study, the "certain itch powder.""The time of itchiness" is a dependent variable because it does change, or can be affected by the independent variable.2. Remember, the advertisement of the "certain itching" "claims to cause 50% longer lasting itches". Hence, we can conclude that the data support the advertisement claims since subject B did itch over 50% longer than subject A. In fact, we are subject B itched for 10 hours, not the 30 minutes subjet A itched.

Which statement best describes the significance of meiosis to sexual reproduction?
A. It produces haploid gametes, with half the number of chromosomes.
B. It creates organisms with better adaptability to the environment.
C. It allows all types of cells to produce two sets of identical chromosomes.
D. It produces up to eight diploid cells, each with the same number of chromosomes.
In meiosis sexual reproduction produce haploid cells to produce gametes and chromosome number is reduced, hence option a is correct.
What is meiosis in sexual reproduction?Gametes or sex cells, which are needed for sexual reproduction are created during meiosis.
It deactivates the sporophytic information while activating the genetic information for the production of sex cells.
Meiosis is a kind of cell division that results in the production of four gamete cells and a 50% reduction in the number of chromosomes in the parent cell. To develop egg and sperm cells for sexual reproduction, this procedure is necessary.
Therefore in sexually reproducing organisms meiosis is important to produce gametes, hence option a is correct.

A. True
B. False
8. Carbon is a relatively large atom allowing it to bind to more atoms than smaller atoms would, thereby making it more versatile.
A. True
B. False
Answer:
Explanation:
Carbon is a non- metallic element with tetravalent, which means carbon posses four electrons which is available to form covalent chemical bonds. it is a chemical element with chemical symbol "C" , it has atomic number of 6, and it is categorized as a member of group 14 in the periodic table. It can form up to 4 covalent bonds, in term of electronegativity, non- metal like Oxygen and nitrogen have a stronger electronegativity compared to carbon which means there is a strong pull on a shared electron. The carbon backbone of a molecule is made up of a string of carbon atoms held together with either single or double bonds.
1)A carbon atom can form up to four covalent bonds.
A. True
2. A carbon atom has six electrons in its outermost shell.
B. False
3. The bond between a carbon and hydrogen atom is a polar bond.
B. False
4. Oxygen and nitrogen have a stronger electronegativity than carbon (e.g., a strong pull on a shared electron).
A. True
5. Bonds between carbon and other atoms are relatively unstable and readily dissociate, resulting in the formation of new molecules.
B. False
6. The carbon backbone of a molecule is made up of a string of carbon atoms held together with either single or double bonds.
A. True
7. The carbon backbone of a molecule comes in a variety of shapes: linear, ring-like, or highly branched.
A. True
8. Carbon is a relatively large atom allowing it to bind to more atoms than smaller atoms would, thereby making it more versatile.
B. False
It is true that carbon atom can form up to four covalent bonds. It is false that carbon atom has six electrons in its outermost shell. It is also false that the bond between a carbon and hydrogen atom is a polar bond. The answers are A. True, B. False, B. False, A. True, B. False, A. True, A. True, and A. True.
Up to four covalent connections can be formed by a carbon atom. The reason for this is that carbon possesses four valence electrons, which enable it to share electrons with other atoms to complete its octet and create durable covalent bonds.
The outermost shell of a carbon atom only contains four electrons, not six. With a total of six electrons—two in its inner shell and four in its outer shell—carbon has an atomic number of six.
A nonpolar, not a polar, bond forms between an atom of carbon and an atom of hydrogen. Due to their identical electronegativities, carbon and hydrogen share the same number of electrons, resulting in a nonpolar covalent connection.
Compared to carbon, oxygen and nitrogen have larger electronegativities, which means that they exert more of a pull on the shared electrons in chemical bonds.
Under normal circumstances, bonds between carbon and other atoms are typically stable and do not easily dissolve.
A chain of carbon atoms bound together by single or double bonds makes up the carbon backbone of a molecule.
A molecule's carbon backbone can take on a variety of forms, such as straight, ring-like, or extremely branched ones.
Compared to lesser atoms, carbon is a comparatively big atom, which enables it to make numerous bonds and attach to more atoms.
Carbon's adaptability is a significant property that contributes to the complexity and diversity of organic compounds.
Thus, the answers are A. True, B. False, B. False, A. True, B. False, A. True, A. True, and A. True.

How does natural selection lead to the development of antibiotic-resistant bacteria?
Answer:
Antibiotic resistance is a consequence of evolution via natural selection. The antibiotic action is an environmental pressure; those bacteria which have a mutation allowing them to survive will live on to reproduce. They will then pass this trait to their offspring, which will be a fully resistant generation.
Survival of the Fittest (Natural Selection):
When bacteria are initially exposed to an antibiotic, those most susceptible to the antibiotic will die quickly, leaving any surviving bacteria to pass on their resistant features to succeeding generations.
Answer:
This is super easy. In every population you have differences between the individuals in that population. If you apply a selection pressure to that population (like antibiotics to bacteria), you will kill all the bacteria that do not have the ability to withstand the drug. Thus, you have selected for those bacteria that happen to have a better ability to withstand it.
How is prey different in wet/dry seasons in Zimbabwe?
Answer:
In the dry season, the animals congregate here freely and happily.
