B Because Cellulose is a polysaccharide consisting of linear chain of numerous linked D-glucose units whereas proteins are formed of number of amino acids linked together by peptide linkage.
Cellulose is a polysaccharide and a structural component of the plant cell. It is a carbohydrate made of many monomers linked together. Thus, B is the correct option.
What is cellulose?Cellulose is an organic chemical that is insoluble in water and is a tough structure classified as carbohydrates. Cellulose is a structural component of plant cells.
It is made by monomer units linked by the beta-1,4 glycosidic bonds and is a biodegradable, tasteless organic compound with the chemical formula (C₆H₁₀O₅)ₙ.
It is the main component of the plant cell wall that provides support and shape due to its fibrous structure. It is made of linear chains of D-glucose units that makes the polysaccharide.
Therefore, option B. cellulose is a carbohydrate.

Answer:
Hemoglobin, or red blood cells, are primarily transporters of oxygen. These cells receive oxygen as air is breathed in through the lungs. Oxygen binds itself to these cells, which then carry it to the heart. The heart circulates the oxygenated blood to cells throughout the body in the process of cellular respiration.

explain how a gis can model the ways that changes in climate can influence human activity
Answer: a Gis helps locate areas where temperatures are high or erratic in comparison to global averages which can help show global warming as well
GIS aids in the identifying the places where temperatures are unusually high or irregular and influences human activity about changes in climate.
What is GIS?"A Geographic Information System (GIS) is a computer program that analyses and displays information that is geographically referenced." It uses data which it gets from the device that have enabled its location.A GIS helps us in gaining a scientific understanding of earth systems on a large scale, allowing us to make more careful and calculated decisions.What is climate?"The long-term weather pattern in a certain location is referred to as climate."Long-term shifts in temperature and weather patterns are referred to as climate change.Hence, GIS tells about the prevailing climatic condition of an area.

Answer:
This question is incomplete
Explanation:
This question is incomplete but there are some general facts that can be made.
Firstly, mitosis only occurs in meristematic tissue of plants which includes apical and lateral meristems
There are 4 phases in a cell cycle
1) G1 (gap 1) phase: This is the first phase of the cell cycle that has to do with an increase in the size of the cell. Major cellular components duplicate in size here.
2) S-phase: DNA replication occurs here.
3) G2 (gap 2) phase: This is the gap phase that comes after the S-phase. The cell undergoes further growth here and the organelles of the cells are also prepared for cell division.
4) Mitotic phase: There are four stages here
i) prophase: Chromosome condenses and becomes visible at this stage. And there is the emergence of spindle fibre from centrosomes.
ii) metaphase: Spindle fibre develops and sister chromatids are attached to
separate spindle.
iii) anaphase: Cohesin, which holds two sister chromatids (of chromosomes) together, breaks down and are pulled towards opposite poles.
iv) telophase: Chromosomes begins to decondense at opposite poles and actual cell division starts as mitotic spindle breaks down.

Mitosis is responsible for growth, repair, and maintenance in an organism because
A. it occurs at a faster rate than meiosis
B. The chromosomes number is reduced by half
C. exact duplicates of each mother cell are produced
D. it is the only process involves replication of genetic material
Mitosis is responsible for growth, repair and maintenance of an organism because it produces all the daughter cells that are genetically identical to one other and therefore creates new available cells that are specific to each tissue for growth and repair.

Geothermal electricity-generating plants are located in regions that often have
droughts
heat waves
volcanoes
tornadoes
Answer: volcanoes
Explanation: geothermal electricity- generating plants are most commonly located around the Ring of Fire, which is a hotspot for volcanoes.
Geothermal electricity-generating plants are located in regions that often have volcanoes. The correct option is c.
What is geothermal electricity?Deep below, hot water is pushed under strong pressure through a well. Therefore, the pressure decreases as the water reaches the surface. When water becomes steam.
A turbine that is connected to an electricity-generating generator is spun by steam. Electricity is produced by geothermal power plants by harnessing the thermal energy of the planet.
The steps that must be taken are as follows.
Deep below hot water is pushed under strong pressure through a well.The creation of thermal energy involves heating water and forcing it through a turbine.It is then transformed into electricity.A generator that aids in the generation of energy is activated by the steam rotating the turbine.Therefore, the correct option is c. volcanoes.

In a paramecium, the nucleus divides first and then the cytoplasm divides, forming two identical daughter cells. Which type of reproduction takes place in paramecia?
Answer:
This type of reproduction is called binary fission.
Explanation:
Binary fission is a type of reproduction in paramecium that involves producing two identical daughter cells from one mother cell. These daughter cells are called clones, and are not genetically distinct from their progenitor. No genetic exchange is involved and they are genetically indequingishable.
The resulting DNA is identical to the original copy and newly copied chromosomes separate into two identical daughter cells with the same chromosome number. All offspring remain identical.
The offspring of a particular cross are 100 percent heterozygous for the trait of plant height. What were the most likely genotypes of the parents? Tt ´ tt Tt ´ Tt tt ´ tt TT ´ tt
Answer:
TT x tt
Explanation:
If the offspring of a particular cross are 100 percent heterozygous for the trait of plant height. the most likely genotypes of the parents is TT and tt.
HETEROZYGOUS:Heterozygosity is a condition in which the genotype of an individual consists of two different alleles of a gene.
According to this question, a gene coding for plant height is involved. The tall allele (T) is dominant over the short allele (t).
This means a heterozygous offspring will have the following genotype: Tt. This genotype will only arise totally i.e. 100% in the offsprings if the parents are both homzygous for the trait i.e. TT and tt.

how the structures of the different chambers and vessels of the heart relate to their functions.
Answer:
Explanation:
The heart can be found at the center of the chest, underneath the sternum in a thoracic compartment. It is made up of four chambers and several valves that regulate the normal flow of blood within the body.
Two chambers called atria are located in the upper portion of the heart and receive oxygen-free blood. The valves that separate these chambers are called atrioventricular valves which is composed of the tricuspid valve on the left and the mitral valve on the right.
On the other hand, ventricles are chambers found on the lower portion of the heart; they pump oxygen-enriched blood into all organs of the body, reaching even the smallest cells. Similar to the atria, the ventricular chambers are also separated by valves. Collectively-termed as semilunar valves, these are comprised of the pulmonary and aortic valve.
The heart also has a wall that is composed of three layers: the outer layer epicardium (thin layer), the middle layer myocardium (thick layer), and the innermost layer endocardium (thin layer). The myocardium is think because it is made up of cardiac muscle fibers.
The structure of the heart is made more complex because of the mechanisms that allow blood to be distributed throughout the body and to return into the heart. Facilitating this continuous process are two types of blood vessels: veins and arteries (16jacktwinwritters). The vessels that bring oxygen-free blood back into the heart are called veins; those that bring oxygen-rich blood away from the heart and to other body parts are called arteries. Functioning in the left ventricle, the largest artery is called aorta. The aorta is considered a main artery in the body. It further splits into two smaller arteries called common iliac arteries.
With regular functioning, the heart is continuously able to supply sufficient amount of oxygen to all parts of the body.
