Answer and Explanation:
Type C3 plants absorb CO2 through the stomata located on the leaves. Upon entering the plant, CO2 will be reduced into smaller molecules, which are simpler sugars and are easier to be metabolized. These sugars are glyceraldehyde-3-phosphate and dihydroxyacetone-phosphate. All of this transformation is done using ATP and NADPH + H + as energy currencies.
Upon entering the plant, CO2 is carboxylized by the enzyme ribulose 1,5-bisphosphate carboxylaseoxygenase, also called Rubisco. It is important to note that C3 plants have a very large variety of leaves, since this group has a very large variety of members such as beans, soybeans, cotton, all woody plants, arros, wheat, most grasses, among others.
C4 plants have some differences in the photosynthesis process. This is because to minimize losses and energy expenditure with photorespiration, which has as one of its functions, the capture of CO2 from the atmosphere, these plants have modified their leaf anatomy. These plants can separate the sheath of the vascular females and the cells of the mesophile (this separation does not exist in C3 plants). This type of plant has a concentration of carbon in the cells of the sheath, this causes RUBISCO to limit its performance only to the CO2 carbylation process and does not participate in photorespiration. We can mention as examples of C4 plants corn, sugarcane, sorghum Euphorbiaceae, among others.

3) The oceans and the atmosphere work together through global currents that do what?
A. Cycle energy and matter to support the biosphere
B. Cycle energy and matter to support plate tectonics
C. Cycle energy and matter to provide nutrients to secondary consumers
D. Cycle energy and matter to support the biosphere as a closed energy system
Answer:
The correct answer is D)
Cycle energy and matter to support the biosphere as a closed energy system
Explanation:
The earth as we know it is a closed energy system that is, matter cannot be introduced or removed from it. Sometimes, rare meterites enter into the system with minimal or no disruption.
Also, energy can enter and leave. The energy mostly referenced here is the sun.
Within the earths system, the lithosphere, hydrosphere, and biosphere materials and energy go through a cycle which helps to support life.
For example, water when heated up by the sun rises as vapour from the earth and oceans into the atmosphere where it cools and condenses. When it cools and condenses, it , in the form of rain, comes down on the earth and oceans. As rain falls down to the earth and runs off the rocks, rocks are broken down into smaller fragments and soils. The hydrosphere comprises of all water bodies on earth. Besides the vapours which are evaporated from the same into the atmosphere, when volcanoes erupt they also send vapourised water into the atmosphere.
So because the earth is a closed system, a change in one sphere effects a change in others. An example is a change in the water cycle.

Both mitosis and meiosis begin with a diploid cell that contains replicated chromosomes. What are the main differences between these two processes, and what types of daughter cells produced by each?
Answer:
Hope this helps :)
Explanation:
Mitosis is the process by which cells duplicate.
Meiosis is a similar process which is just used to make reproductive cells such as eggs or sperm.
In mitosis, the cell DNA arranges into 46 chromosomes, duplicates, and then divides into two new cells.
In meiosis, the same duplication occurrs except four cells are created, each with only 23 chromosomes. (You know how you get half of them from each parent? This is so that the offspring have genetic variation.)
Another thing to notice about meiosis is that the cells are not identical like in mitosis, which simply duplicates them. Furthermore, in males all four sex cells are used as sperm but in females only one of these cells develops into an egg whereas the rest, called polar bodies, are reabsorbed into the body.
Answer:
Meiosis has two cell divisions and results in four haploid daughter cells with genetic variation, while mitosis has one cell division and results in two identical daughter cells.

Why is the process for developing a vaccine usually lengthy? A. Obtaining the necessary supplies for testing is complicated. B. Recruiting scientists to work on a vaccine project can be difficult. C. Ensuring that a vaccine is safe requires multiple rounds of human testing. D. all of the above
Answer:
C. Ensuring that a vaccine is safe requires multiple rounds of human testing
Explanation:
Vaccination is the process whereby a substance called a VACCINE is administered in order to prevent a particular disease. The vaccine is actually a substance given to help the body's defense system combat a particular infection or disease. A vaccine, which is usually a harmless strain of a pathogen, prepares the antibodies of an organism to fight against the actual pathogenic organism.
As rightly said in the question, developing a vaccine can be a very long process. This is because the vaccine has to go through series of testing on healthy humans before releasing to the public in order to ascertain that there are no risks or dangers attached to the usage. The process of ensuring that a vaccine is safe requires multiple rounds of human testing, which is time-consuming.

Answer:
The process represented is photosynthesis and the primary source of
energy for the process is the Sun.
Explanation:
The given diagram shows the process known as Photosynthesis and the primary source of energy for this process is the Sun. Thus, the correct option is D.
What is Photosynthesis?
Photosynthesis is a process by which plants make their food. Plants and other organisms convert light energy into chemical energy by this process that later can be used to fuel the organism's activities.
In this process, plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar. Plants transform carbon dioxide into oxygen with the help of sunlight and animals need oxygen to survive. Plants also fix carbon dioxide by checks the air quality.
In plants, photosynthesis takes place in chloroplasts, which contain a pigment called the chlorophyll. Chloroplasts are surrounded by double membrane and contain a third inner membrane, called the thylakoid, which forms long folds within the organelle.
Therefore, correct option is D.

J.S. Hart (Can. J. Zool. (1956) 34, 1, pp. 53-57) described seasonal changes in insulation of the fur of nine species of arctic and North temperate zone mammals. Relative seasonal changes ranged from 12 to 52% of the winter coat insulation value. Absolute changes were greatest in the largest mammals with thickest fur. Indicate if the following statements that are true or false.a. Increasing fur thickness would reduce conduction between the animal and the environment True or Falseb. Animals with thicker fur compared to those with thinner fur have different metabolic rates when measured at the same ambient temperature below the thermal neutral zone (TNZ). True or falsec. Endothermic mammals are most often classified as homeotherms. True or falsed. Fur does not affect the rate of convective and conductive heat loss in the cold. True or falsee. Changes in fur thickness is associated with an expression of a unique phenotype that optimizes fitness for a given environmental temperature.
True or false
Answer:
a. True
b. True
c. True
d. False
e. True
Explanation:
The fur plays a critical role as an insulator and it may be a greater thickness during the winter. The fur allows the animals to reduce their heat loss, thereby thicker fur may serve as an additional layer of insulation during the winter. Endothermic animals such as birds and mammals are capable of maintaining a constant body temperature independent of the environmental conditions. In a similar way, the homeothermic animals are able to maintain stable body temperature by regulating their metabolic processes (i.e., also mammals and birds can be classified as homeothermic animals). The study above cited (Hart, 1956) was aimed at collecting comparative information to support the role of fur as insulation in Canadian mammals and thus understand seasonal acclimatization in general. In this regard, Hart concluded that although seasonal differences could be observed in all species analyzed, the greatest absolute changes were observed in larger animals (that is, animals having the thickest fur).

When an ionic compound such as sodium chloride (NaCl) is placed in water, the component atoms of the NaCl crystal dissociate into individual sodium ions (Na+) and chloride ions (Cl-). In contrast, the atoms of covalently bonded molecules (e.g., glucose, sucrose, glycerol) do not generally dissociate when placed in aqueous solution. Which of the following solutions would be expected to contain the greatest number of solute particles (molecules or ions)?
A) 1 L of 0.5 M NaClB) 1 L of 0.5 M glucoseC) 1 L of 1.0 M NaClD) 1 L of 1.0 M glucoseE) C and D will contain equal numbers of particles.
Answer:
The correct answer is C) 1 L of 1.0 M NaCl
Explanation:
NaCl is a ionic compound so it dissociates in water into Na⁺ and Cl⁻ ions. Glucose is a covalent solute so it does not dissociates into ions. So, when we dissolve NaCl we have twice the amount of particles in solution in comparison with glucose. According to this:
A) and B) are solutions with the same concentration (0.5 M) but NaCl solution will have more solute particles than glucose.
C) and D) are solutions with more solute amount because they are more concentrated (1 M), but NaCl solution will have more solute particles than glucose solution ( 1 mol of Na⁺ ions + 1 mol of Cl⁻ ions).
The solution with the greatest solute particle number is C).
