3. Carbohydrates, Proteins, Lipids, and Nucleic acids
4. Carbohydrate provide energy; Proteins serve as structural elements;
Lipids serve as structural components of membranes;
Nucleic acids store and transmit genetic information
5. Proteins are considered polymers while Lipids are not because proteins are composed of monomeric subunits of amino acids whereas lipids do not have monomeric subunits.
Explanation:
1. The major elements of life are Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorus and Sulfur as they are found in many structures of living organisms- in proteins, carbohydrates, nucleic acids and lipids.
2. Carbon has the ability to form different large and complex structures because:
(I) its ability to catenate which is the ability to combine with one another to form straight, branched chain or ring compounds containing many carbon atoms.
(ii) carbon can form single, double and triple with itself and other life elements.
(iii) the relative stability of the covalent bonds formed by carbon.
3. Four groups of organic compounds found in living things are Carbohydrates, Proteins, Lipids, and Nucleic acids.
4. Carbohydrate provide energy; Proteins serve as structural elements;
Lipids serve as structural components of membranes;
Nucleic acids store and transmit genetic information
5. Polymers are large molecular weight compounds built up from subunits called monomers.
Proteins are considered polymers because they are large molecular weight molecules composed of monomeric subunits of amino acids.
Lipids are not considered polymers because individually, they are not very large molecules and do not have monomeric subunits rather are composed of long fatty acids chains linked to a glycerol molecule.
When solar energy is more spread out, the sun is at an angle, What happens to the light energy??
Answer:

A simple diagram of a DNA molecule is shown below. Which of the following is represented by X?
(photo above)
Answer:
From the diagram X = base pairs
Explanation:
Genetic information stored within DNA is used for growth, reproduction, and cell repair. DNA, deoxyribonucleic acids, are long-chain, helical macromolecules made of specific sequences of covalently bonded monomers called nucleotides.
Nucleotides comprise:
a 5-Carbon deoxyribose sugar, one nitrogenous base (adenine, guanine thymine, and cytosine) and a phosphate group.Nitrogenous bases cause nucleotides to form hydrogen bonds with other nucleotides as base-pairs. The four types of bases each make the nucleotides Thymine and Cytosine (pyrimidine bases) along with Guanine, and Adenine, (purine bases). In base-pair formation, Adenine forms double bonds with Thymine, and cytosine forms triple bonds with guanine.
Candice is examining a cell under a microscope. She has identified a cell wall, a nucleus, and chloroplast. What type of organism does this cell most likely belong to.
1.plant
2.fungus
3.animal
4.bacterium
Answer:
1. Plant
Explanation:
Only a plant has a cell wall, chloroplast, and nucleus. Since eukaryotes are the only ones with a nucleus, that cancels out bacteria and fungi. Since there is a chloroplast, you can tell that the cell has to be one of an autotroph which gives you plant.

Answer: They don't go through photosynthesizes in winter.
Answer:
Photosynthesis actually occurs in the green parts of the leaf called chloroplasts. These chloroplasts are what give leaves their color. But as leaves start to lose their green colors in fall and winter, they can no longer do photosynthesis. However, there are some deciduous trees, such as aspens, that have green stems

A scientist extracts a molecule from a cell that includes phosphorus, a nitrogen base and a sugar. What macromolecule did the scientist most likely extract to
study?
A. Carbohydrate
B. Protein
C. Triglyceride
D. Nucleic Acid
Answer:
D
Explanation:
The correct answer would be Nucleic Acid.
A typical nucleic acid has 3 components which include:
A purine or pyrimidine nitrogenous baseA phosphate groupA 5-carbon sugarThe purine base includes adenine and guanine while the pyrimidine base includes thymine/uracil and cytosine. The 5-carbon sugar could be ribose or deoxyribose depending on if the nucleic acid is ribonucleic or deoxyribonucleic acid.
The only macromolecule that contains the 3 components of the options A to D is the nucleic acid. Hence, the correct option is D.
Seeds that are planted upside down are still able to grow into mature plants. Which explanation
best explains this phenomenon (a)The roots change into branches in the branches turn to roots(b) The roots grow towards the force of gravity and the stem goes away(c)The plant will become a smaller version of a mature plant(d) roots always grow toward the dark and the stem grows toward the light
The explanation that best explains this phenomenon is: the roots grow towards the force of gravity and the stem goes away
WHAT IS GEOTROPISM?The parts of a plant can be divided into shoot and roots. The root of the plant is the part that grows below the ground surface in order to anchor the plant.
When a seed germinates, the root part of that seed grows towards gravity i.e exhibits geotropism while the shoot part grows away from gravity i.e. upwards.
Hence, if a seed is planted upside down, it will still grow into an erect mature plant because the root will grow downwards towards gravity (positive geotropism) while the stem grows upward away from gravity (negative geotropism).

Root systems are classified as fibrous root systems and taproot systems.
Which property distinguishes the two types of root systems from each other?
A)
the method of water absorption
B)
the branching pattern of the roots
C)
the presence of xylem and phloem
D)
the growth rate of the roots
Answer:
B) the branching pattern of the roots
Explanation:
Plant roots function as anchors, food storage and aid in the uptake of water and minerals- other modifications include gas exchange and chemical signaling.
Root systems are mainly classified as taproots, usually found in dicots or fibrous roots found in monocots - some plants are a varying combination of the two systems. While tap roots consist of a larger, vertical main root surrounded by smaller lateral roots, fibrous roots are typically a dense network of roots that grow near the surface of the soil.
Taproots are thought to be more common in plants inhabiting regions experiencing water scarcity, while fibrous roots are thought to grow in more lush, water-abundant regions.
Examples of these roots systems include...
taproots: dandelions, carrots, turnipsfibrous roots: grasses, cornJudy used the following soil triangle to identify a sample of soil as silty clay.
Soil texture triangle. Clay soil is approximately 45 percent or less sand, 50 percent or more clay, and 40 percent or less silt. Silty loam soil is approximately 50 percent or less sand, 30 percent or less clay, and 50 percent or more silt. Sandy clay soil is approximately 45 to 65 percent sand, 35 to 55 percent clay, and 25 percent or less silt. Sandy clay loam soil is approximately 45 to 80 percent sand, 20 to 35 percent clay, and 35 percent or less silt.
Which description of soil likely allowed Judy to make this identification? (2 points)
a
Mostly large particles, with a gritty texture, 75% clay, 15% sand, and 10% silt
b
Mostly large particles, with a sticky texture, 65% clay, 10% sand, and 25% silt
c
Mostly small particles, with a sticky texture, 50% clay and 5% sand, and 45% silt
d
Mostly small particles, with a smooth texture, 30% clay, and 25% sand, 45% silt
Answer:
its C
Explanation: I worked it our w/ the triangle and this seemed the most logical answer. plus had the same question on a test ~5min before this post so I know for sure its right.
Soil texture or Soil profiling is referred to as the proportion of primarily three different types of particles, clay, sand, and silt.
The description that is similar to Judy's soil triangle is that most small particles, with a smooth texture, are 10% sand, 50% clay, and 40% silt.
The soil profiling can be explained as:
1. Clay is one of the smoothest and fine particles of the soil. It has a diameter of fewer than 0.2 millimeters. Clay soil is 40% or more is clay, less than 40% is silt, and 45% or less is sand.
2. Sand is a coarse particle and is the largest mineral in the soil. The particle is gritty and has a diameter of 0.05 to 0.02 mm.
3. Silt is found in a high percentage of the soil and gives a smooth texture to the soil.
Thus, the correct answer is Option C.

Macromolecules are made up of single units known as monomers that are joined by covalent bonds to form larger polymers.
A ball bounces on the ground. How do the ball and the ground act on each other?
Explanation:
It will continue to fall under the influence of gravitational acceleration, but now, a normal force from the ground surface, opposing the force due to gravity, will act on the ball.This all means that the ball is pushing on the ground with a force greater than its own weight, so acceleration must point upward.
