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.
Each nucleotide is composed of three parts. The picture to the right shows a strand of DNA nucleotides linked together. What is the correct name of the molecule indicated?
Answer
F
Deoxyribose sugar
G
Nitrogenous base
H
Phosphate group
J
Hydrogen bond
Answer:
G. Nitrogenous base
Explanation:
Double-stranded DNA (Deoxyribonuclease) molecules store genetic information. Their 5-carbon deoxyribose sugar, phosphate and one of four nitrogenous bases from which nucleotides derive their name:
Adenine (A)Guanine (G)Cytosine (C)Thymine (T).The nucleotides on a single strand are bonded together via covalent bonding. Base pairs are formed between nucleotides on opposite strands, due to hydrogen bonding between bases. For instance, Adenine forms double bonds with thymine, while cytosine forms triple bonds with guanine.
Identify one organism, one population, and one community
Answer:
The study of organisms, populations and communities examines how organisms interact with each other and their environment at individual, population and community levels. To characterize these interactions, NEON quantifies and observes interactions among multiple organisms and their environments. By sampling a variety of organisms in aquatic and terrestrial systems, NEON provides data on individual traits, population dynamics and the composition of communities. Integrated with other data collected across NEON sites, the project produces data in the areas of biodiversity, infectious diseases and invasive species.

Which of the following phrases describe the function of the digestive system?
l. Smooth, muscular tube connects the mouth to the stomach
ll. Muscular action in the esophagus pushed food to the stomach
lll. Structures called the microvilli to increase the surface area of the intestines
lV. Nutrients are made available to the body's cells
A. l and ll
B. ll and lll
C. ll and lV
D. lll and lV
Answer:
B. ll and lll
Explanation:
The question above is asking for the "function" of the Digestive System. Function refers to how the digestive system actually works.
I is not related to the function of the digestive system. It only describes the "esophagus."
II is called the "Peristalsis." This is one of the functions of the digestive system. This allows the food to move down the GI tract.
III is part of the process called "Segmentation." This is one of the functions of the digestive system. The increase surface area of the microvilli expands 25 times and this allows greater absorption of food.
IV is not related to the function of the digestive system.

How do Limiting factors affect biotic potential? Please hurry and help me
Biotic factors that a population needs include food availability. Abiotic factors may include space, water, and climate. The carrying capacity of an environment is reached when the number of births equal the number of deaths. A limiting factor determines the carrying capacity for a species.
What happened when there was not enough carbon dioxide in the atmosphere to trap the sun's heat about 600 mya?
Answer:
Decreased Temperatures
Explanation:
Because carbon dioxide traps heat in the atmosphere, a lessening of atmospheric carbon dioxide concentrations would mean that more heat could escape into space. This would result in a net decrease in the Earth's average temperature, assuming other factors remain the same.

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
Explanation:
Compare the structure and function of each type of biological macromolecule.
Explanation:
Proteins, carbohydrates, nucleic acids, and lipids are the four major classes of biological macromolecules—large molecules necessary for life that are built from smaller organic molecules. 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.

Judy 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.

The process of forming ATP is? A) Digestion. B) Cellular Respiration. C) Metabolism. D) nutrition.
Answer:
[tex]\boxed {\boxed {\sf B. \ Cellular \ respiration}}[/tex]
Explanation:
First, let's analyze each process.
A. Digestion
This is the process of breaking down food.
B. Cellular respiration
This is the process of converting glucose and oxygen to carbon dioxide, water, and ATP.
C. Metabolism
This isn't really a process. It's the collection of all the chemical reactions in the body to keep the body functioning.
D. Nutrition
This term also isn't a process. Nutrition involves food, nutrients, and health.
We are looking for the process that forms ATP. Therefore, the best answer choice is B. Cellular respiration
The process of forming ATP is Cellular Respiration. Therefore option B is correct.
The process of forming ATP (Adenosine Triphosphate) is primarily through Cellular Respiration.
ATP is the main energy currency in cells, providing the energy needed for various cellular activities.
Cellular respiration is a series of metabolic reactions that occur in the mitochondria of cells, where organic molecules (such as glucose) are broken down and oxidized to release energy.
This energy is used to synthesize ATP from ADP (Adenosine Diphosphate) and inorganic phosphate (Pi).
Through cellular respiration, cells efficiently convert the energy stored in food molecules into a readily usable form of energy (ATP).
Which powers essential cellular processes, including muscle contraction, active transport, and synthesis of macromolecules.
Therefore option B Cellular Respiration is correct.
