Once a plant obtains carbon dioxide from the atmosphere it produces __________ as an energy source through photosynthesis.
A. Water
B. Glucose
C. Carbon
D. Carbon Dioxide
answer:
B
Explanation:
6CO2+6H2O+energy from sun=C6H1206+6O2
C6H12O6 is a form of glucose
Once a plant obtains carbon dioxide from the atmosphere it produces glucose as an energy source through photosynthesis. Thus, option B is correct.
What is photosynthesis?Photosynthesis is the process by which green plants prepare there own food in the presence of sunlight and during this process heat energy converted into chemical energy.
Leaf is known as site for photosynthesis it means the process of photosynthesis that occurs in leaf. The main function of leaf is to produce food material for plants which will help plants to get nourished.
Plants absorb nitrates in water through their roots without nitrates, the amount of chlorophyll in leaves reduces.
Nitrate is a common inorganic ion found in plants that is required for proper growth and development. Many growers include the addition of nitrates in their nutrient regiment to stimulate plant growth. Plants acquire nitrate through root intake from the soil and water around them.
Therefore,Once a plant obtains carbon dioxide from the atmosphere it produces glucose as an energy source through photosynthesis. Thus, option B is correct.

Which statement best describes a difference between saturated fats and unsaturated fats?
A. Unsaturated fats tend to have higher melting points because they have only single carbon-carbon bonds, which allow the molecules to be straight.
B. Unsaturated fats tend to have lower melting points because they have at least one carbon-carbon double bond, which causes the molecule to bend.
C. Unsaturated fats tend to have lower melting points because they have only single carbon-carbon bonds, which allow the molecules to bend.
D. Unsaturated fats tend to have higher melting points because they have at least one carbon-carbon double bond, which causes the molecule to be straight.
Answer:
B.
Explanation:
Unsaturated fats are fats that have one or more carbon-carbon double bond in their chain. The double bond causes the molecule to bend. The molecules do not stack well, which causes the intermolecular forces to be much weaker than those of saturated fats. This causes the melting points to be lower for unsaturated fats.
Hope that helps.
The statement that differentiates unsaturated and saturated fats is "Unsaturated fats tend to have lower melting points because they have at least one carbon-carbon double bond, which causes the molecule to bend".
WHAT IS SATURATED AND UNSATURATED FATS?
Saturated fats are a type of fats that lack carbon to carbon double bonds in their structure, however, in unsaturated fatty acids, there is at least one double bond in the chain. Due to the double bonds possessed by unsaturated fats, their molecules tend to bend structurally. Unsaturated fats are mostly liquids at room temperature, as opposed to saturated fats which are solids. Hence, unsaturated fats will possess a low melting point compared to saturated fats.Therefore, Unsaturated fats tend to have lower melting points because they have at least one carbon-carbon double bond, which causes the molecule to bend.

The chemical known as Adenosine triphosphate is used by cells to grow and function.
What is Adenosine triphosphate?The most abundant energy carrier molecule in cells is adenosine 5'-triphosphate, or ATP. This molecule is comprised of three phosphate groups, a nitrogen base (adenine), and a ribose sugar.
Adenosine triphosphate (ATP) is the cellular power source for use and collection. ATP is a nucleoside triphosphate with the structure of a nitrogenous base (adenine), a ribose sugar, and three serially bonded phosphate groups.
Thus, the chemical known as Adenosine triphosphate is used by cells to grow and function.

The habitat of a rattlesnake is the hot, dry desert. Could this organism live in the
cold, Artic habitat? *
Answer:
No, a rattlesnake would not be able to survive in the Arctic. This reptile is specially equipped with features suited to a hot desert, which would be a hinderance in a cold desert rather than an advantage. Also cold-blooded organisms must be able to bask in the sun to maintain a stable body temperature, but in the Arctic, that wouldn't be possible.

C .
Explanation:
They perform a valuable service as Earth's cleanup crew. Without decomposers, dead leaves, dead insects, and dead animals would pile up everywhere. Imagine what the world would look like! More importantly, decomposers make vital nutrients available to an ecosystem's primary producers—usually plants and algae.

Some organelles, such as the endoplasmic reticulum and Golgi bodies, have a large and folded structure. What is an advantage of these organelles having a folded structure?
Answer:
Explanation:
In endoplasmic reticulum, many folds leads to an increase in surface area for ribosomes to attach which allows for protein synthesis to occur at an efficient rate.
mitochondria has two membrane,
It has an inner membrane which is folded inside the other. The fold create cristae, which is the site for a portion of cellular respiration.
The folds also enables a large surface area that makes chemical process to occur in an efficient way.

What are the functions of root system?A fibrous root system forms a dense network of roots that is closer to the soil surface. An example of a tap root system is a carrot. Grasses such as wheat, rice, and corn are examples of fibrous root systems.
The roots of the plants are found underground, and their important functions are water and nutrient absorption. Root systems are classified into 3 they are: Tap Root systems, Fibrous Root systems, and Adventitious Root systems.
Its primary functions are anchorage of the plant, absorption of water and dissolved minerals and conduction of these to the stem, and storage of reserve foods.

Human gametes should contain chromosomes each. This number would be considered the
(haploid/diploid) number for humans. The symbol for this is
Answer:
Human gametes should contain 23 chromosomes each. This number would be considered the haploid number for humans. The symbol for this is n.
Explanation:
Gametes are an organism's reproductive cells. Female gametes are called egg cells, and male gametes are called sperm.
In most organisms, somatic cells (all cells except for gametes) are diploid, whereas the gametes tend to be haploid. Haploid cells have a single set of chromosomes, while diploid cells have two sets of chromosomes.
When it comes to human cells, somatic cells have 46 chromosomes. This means that each gamete has 23 chromosomes. This is called the haploid number and is marked by a lowercase n. This number refers to the total number of chromosomes found in a gamete (for human cells n=23).
- What is the ultimate process that moves the tectonic plates?
A. Gravitational Forces
B. Convection
C. Solar Winds
D. Unknown - Still Investigating
Answer:
I would say B - Convection
Explanation:
it is volcanos and earthquakes that move the tectonic plates... but those act like convection currents...
-Solar Winds come from the Sun and they are reflected off of Earth's magnetic shield so that can't be correct.
-Gravitation does play a role yes but I can not say that it actually causes it... (Gravity holds everything in orbit and also together... and it helps keep things on Earths surface -it is the reason why we can still breath-)
-Unknown - Still Investigating, The reason why the tectonic plates move "was" discovered... or at least it is believed to have been. But I do not doubt that they are still studying it... because they probably are still investigating
-The convection currents move the plates. Where convection currents diverge near the Earth's crust, plates move apart. Where convection currents converge, plates move towards each other.

Water molecules have select answer a lesser a greater an equal attraction for sodium and chloride ions than sodium and chloride ions have to each other.
Answer:
A greater attraction
Explanation:
Water molecules have A GREATER ATTRACTION for sodium and chloride ions than sodium and chloride ions have to each other.
This is because when salt is added to water, it dissolves, which depicts the level of the covalent bond of water is stronger by separating the ionic bond between sodium and chloride, otherwise, the salt would not have been able to dissolve.

Answer:
A. Genes are found within chromosomes.
Explanation:
A chromosome is a single linear, coiled DNA molecule that contains part or even all the genetic material of an individual. On the other hand, genes are chromosomal segments that contain the instructions required to encode a specific protein, which is stored in the form of a sequence of nucleotides. In consequence, a chromosome may have many genes. In biology, a gene is considered to be the basic physical and functional unit of heredity.
