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

Answers

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, corn

When solar energy is more spread out, the sun is at an angle, What happens to the light energy??

Answers

Answer:

Explanation:

As the sun angle decreases, light is spread over a larger area and decreases in intensity (energy input per unit area). Figure 4.10 illustrates the effect of changing sun angle on the area illuminated and intensity of heating at different sun angles. hope i helped :)

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

Answers

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 sugar

The 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.

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

Answers

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.

This is most likely a plant because plant cells contain cell walls and chlorophyll for photosynthesis.

A ball bounces on the ground. How do the ball and the ground act on each other?

Answers

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.

Please give me an answer and don’t confuse me because everybody is giving me different answers :(

Answers

Answer:

In plants and some protists, such as algae

Explanation:

Chloroplasts are organelles found in cells of plants and some protists, such as algae. They contain a pigment called chlorophyll, which makes them green. Thanks to this protein, they conduct photosynthesis - a process in which energy from sunlight is converted into sugars, i.e. food. In this process, oxygen is being released.

A simple diagram of a DNA molecule is shown below. Which of the following is represented by X?
(photo above)

Answers

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.

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).
