What allows oxygen to create polar molecules?
Answer:
That the oxygen atom attracts electrons a little more strongly than hydrogen does. So even though the electrons from each atom are attracted by both the oxygen and the hydrogen, the electrons are a bit more attracted to the oxygen.
Which of the following best describes the hydrolysis of carbohydrates
Answer:
The addition of a water molecule breaks a covalent bond between sugar monomers
Explanation:
The digestion of carbohydrates by enzymes is an example of a hydrolysis reaction.
Carbohydrates are chains of monosaccharides. Hydrolysis involves the addition of a water molecule that cleaves the covalent bond between the molecules of sugar.
The reverse reaction is a condensation reaction, the joining of sugar monomers to create a carbohydrate releases a molecule of water.
media would growth provide evidence that genetic transfer had occurred between the two strains of bacteria? Select all that apply. Select all that apply. bio- leu- bio- trp- trp- leu- leu- trp- bio- none of the above
Answer:
bio- leu
leu- trp- bio
Explanation:
The media growth 'bio- leu ' and 'leu- trp- bio' would offer evidence that genetic transfer had taken place between the two strains of bacteria. These two strains of Escherichia Coli substantiate the genetic recombination through the conjugation of bacterial cells which was the prominent aim of experiment displayed by Lederberg and Tatum's genetic analysis. This mapping of chromosome E. coli assisted in recieving the ph.
Why have plants in the alpine biome adapted to survive on limited nutrients?
Answer:
The soil in the alpine biome is rocky and nutrient poor. Plants that live in the alpine biome must be suited to the nutrient poor soil.
Explanation:
The plants living in the alpine biome are adapted to survive on limited nutrients as the conditions in the alpine biome is harsh and not favorable. Hence, the plants have to adapt the mountain climate.
What are adaptations?An adaptation is any physical or behavioral feature of an organism that helps them to survive better in their environment. In other words, an adaptation is something that helps them in finding food, water, mates, and shelter.
The alpine climate is the typical climate for elevations above the tree line, where the trees fail to grow due to cold conditions. The climate of alpine biomes is also referred to as the mountain climate or highland climate.
Plants which are living in alpine biomes are typically low growing due to the extreme environmental conditions. There are only about 200 species of alpine biome plants which have adapted to life in cold temperatures and sparse rainfall.

Maltase is an enzyme that catalyzes the hydrolysis of the disaccharide maltose. This process occurs during human digestion when maltase is secreted by the intestine and then converts maltose into glucose. Which two classes of biomolecules are directly involved in this process?
A .proteins and carbohydrates
B. lipids and proteins
C. carbohydrates and nucleic acids
D. carbohydrates and lipids
Answer: D
Explanation:
Carbohydrates and nucleic acids are the two main classes of biomolecules which are involved directly in the process of digestion of maltose through maltase enzyme. Thus, the correct option is D.
What is Maltase?Maltase is a an enzyme which belongs to the alpha-glucosidase enzyme family. These are found in the small intestine's brush bordered cells. The hydrolysis of the disaccharide maltose into two simple sugars such as glucose is catalyzed through the enzyme maltase.
Maltose is a disaccharide which is produced by the enzymatic hydrolysis of starch, which is a homopolysaccharide and this is catalyzed by the enzyme amylase. Maltose sugar is further hydrolyzed by the enzyme maltase to produce two molecules of d-glucose.
Therefore, the correct option is D.

Identify the RNA bases that would pair up with the DNA sequence TGCACT
A. TGCACT
B. ACGTGA
C. UCGUGA
D. ACGUGA
RNA and DNA are two nucleic acids that differ in nitrogen bases. ACGUGA is the RNA base pair that will pair with TGCACT, of DNA. Thus, option D is correct.
What is complementary base pairing?The complementary base pairing has been defined as the pairing of the nucleotides with each other to form the RNA or DNA structures. The base pairs with each other through hydrogen bonding where the reaction occurs between the purines and pyrimidines.
The RNA and DNA structure differs as RNA is made of ribonucleic acid with four nitrogen bases, A, U, G, and C, whereas DNA is made of deoxyribonucleic acid with bases, A, T, G, and C. Both differ in sugar and one nitrogenous base.
According to Chargaff's base pairing rule the purines (adenine and guanine) pair with pyrimidines (cytosine, thymine, and uracil). A forms a double bond with T in DNA and U in RNA, and G forms triple bonds with C.
The given DNA sequence is: TGCACT
The RNA bases for the sequence will be: ACGUGA
Therefore, option D. ACGUGA is the complementary base pair.

C. A passenger walking down the train aisle O D. A tree outside
If someone is riding on a train, the object will appear to be stationary from the train seat, such as a poster on the train, which is present in option B, and this example explains the nature of the motion.
What is the significance of the motion?When traveling by train, some substances appear to be moving along with the train, while others appear to be stationary. This is due to the relative nature of motion, and due to this person inside the train, objects outside the train are moving because the train is in motion, whereas objects inside the train are stationary.

Which path shows how gravity causes water to move?(APEX)
Answer:
Stream , Tributary, River, and Lake
Explanation:
Stream tributary River and Lake is the path for gravity causes water to move.
What is Path for water?Evaporation, condensation, and precipitation are typically taught as three separate but interconnected stages of the water cycle. Although this is a useful model, the actual situation is far more nuanced.
Water moves through ecosystems on Earth in a variety of ways that are incredibly complicated and still not fully understood.
For better weather, climate, water resource, and ecosystem health forecasting, NOAA is working to increase understanding of the water cycle at all sizes, from the global to the local.
Evaporation, condensation, and precipitation are frequently taught as three basic, circular processes that make up the water cycle. This is a good paradigm, but in practice things are much more nuanced.
Therefore, Stream tributary River and Lake is the path for gravity causes water to move.

What is the function of the eukaryotic cell?
Answer: Eukaryotic cells have a true nucleus, which means the cell's DNA is surrounded by a membrane. Therefore, the nucleus houses the cell's DNA and directs the synthesis of proteins and ribosomes, the cellular organelles responsible for protein synthesis.
Explanation: Mark as brainllest

Describe the difference between the different forms of electromagnetic
radiation and how scientists classify the types of electromagnetic radiation.
Answer: Light is a form of electromagnetic radiation. Other forms of electromagnetic radiation include radio waves, microwaves, infrared radiation, ultraviolet rays, X-rays, and gamma rays. The only difference between them is their wavelength, which is directly related to the amount of energy the waves carry. Scientists classify them by the frequency of their wavelength, going from high to low frequency. When a wave has a lot of energy, it could be a gamma ray or x-ray. If it has low frequency, it has less energy and could be a TV or radio wave.
