Which statement best describes the relationship of photosynthesis and energy?
The process of photosynthesis is energy-storing because the process converts light energy into chemical energy,
which is stored in the bonds of glucose.
The process of photosynthesis is energy-releasing because the process converts light energy into free energy that
can be used for cell functions.
The process of photosynthesis is energy-conserving because no energy is used throughout the process of forming
glucose and oxygen molecules.
The process of photosynthesis is energy-wasting because photosynthesis is an inefficient process that depletes the
cell of energy stored in the bonds of glucose.
Answer: The process of photosynthesis is energy-conserving because no energy is used throughout the process of forming glucose and oxygen molecules.
Explanation: Plants create glucose through sunlight for food, which conserves energy

Which of the following relationships is incorrect
Chloroplast is not a site of lipid synthesis, it is the site of performing photosynthesis Therefore, option A is correct.
What are chloroplasts and their functions?An organelle found in the cells of plants and some algae called a chloroplast is where photosynthesis, the process by which solar energy is transformed into chemical energy for growth, takes place.
All green tissues in plants and algae contain chloroplasts in their cells. In photosynthetic tissues that don't appear green, such as the brown blades of gigantic kelp or the red leaves of some plants, chloroplasts are also present.
Thus, the cell wall provides support and protection to the cell, rough ER is the site of protein synthesis, the nucleus holds genetic material, and the chloroplast is the site of photosynthesis. Therefore, option A is correct.

Which of the following plant structures allows plants to take in the carbon used in photosynthesis?
Which of the following plant structures allows plants to take in the carbon used in photosynthesis?
roots
vascular bundles or veins
stomata
cuticle
chloroplasts
Answer:
Stomata
Explanation:
Photosynthesis is a unique phenomenon in certain organisms like plants. It is the process whereby they produce their food, in form of an organic compound called GLUCOSE. To synthesize this sugar, plants need a carbon source.
Plants utilize carbon dioxide (CO2), which is an inorganic carbon compound as CARBON SOURCE to synthesize glucose molecule in the process of photosynthesis. This carbon dioxide (carbon) is taken in by the plants via their STOMATA, which is a pore or opening present on their leaves.
The STOMATA opens and closes in order for gaseous exchange to occur i.e. take in CO2 (carbon dioxide), expel O2 (oxygen).

stomata

Explanation:
Filled-in symbols in the pedigree that follows designate individuals suffering from deafness.a. (2 points) Study the pedigree and explain how deafness is being inherited.b. (2 points) What is the genotype of the individuals in generation V
Answer:
According to the pedigree, It is clear that the F1 generation is not affected but their offspring are affected in F2, which explains that the deafness presented with the pedigree is recessive. It should be an Autosomal recessive inheritance as it is found in both male and female offsprings.
As it is found that the parents are affected in 5th gen and 6th generation but their offspring are not affected which means there must be more than one genes controlled this disorder
B. In 5th generations mentioned above offspring is unaffected but parents are affected, to find the genotype of the individual let assume there are two genes responsible for it A and B, and mutation in any one of them can result in deafness.
So in IV generation Individuals 5 and 6 have genotypeAAbb and aaBB; both are deaf.
gametes:- Ab & aB.
So, the genotype of all offsprings will be AaBb means all are normal.
Deafness is an autosomal recessive disorder as the first generation is unaffected and the genotype of the fifth generation is AaBb.
What are pedigree and genotype?Pedigree is a chart representation of the phenotype of specific genes of the organism and its inheritance from the ancestral family. The pedigree can be used for the analysis of the heritable disease and illness in the family root.
The deafness illness in the pedigree is recessive as the first generation of the pedigree remains unaffected but the later generation is affected and is diseased.
From the chart, deafness can be said to be an autosomal recessive disorder as some generations are unaffected and in some the disease is present. More than one gene is controlling the disease as the fifth and sixth generations are affected but not their offspring.
The parent of the fifth generation are affected but their progenies are normal to know the genotype let's assume the genes A and B to be responsible for the disease and the mutation in any one of the alleles will result in deafness.
Hence, the genotype of the parents 5 and 6 in the fourth generation will be AAbb and aaBB as both of them diseased or deaf, the offsprings produced from their cross will be AaBb that is all the offspring of the fifth generation will be normal and unaffected.
Therefore, the genotype of the fifth generation in the pedigree is AaBb.

Explanation:
It will compare that neither has an affect on the population and it will also compare that both will be equal to one another.
What is population?The term "population" refers to all citizens who are either permanently residing in a country or who are just passing through. This indicator reveals how many people typically reside in a certain area.
Growth rates are the population changes that occur each year as a result of births, deaths, and net migration.
The total population also includes national military forces deployed overseas, merchant mariners at sea, diplomatic staff based abroad, civilian foreign nationals residing in the nation, and internally displaced people residing in the nation. Demographic tools like population predictions are frequently used.

Answer:
System that receives and transmits information and responses, in addition to work with electrical impulses is the Nervous system.
Explanation:
The nervous system (NS) is responsible for the control of all the organs and functions of the body. The neuron is the functional unit of this system, allowing the transmission of information through nerve impulses, generated by the difference in potential of its cell membrane.
NS is divided into:
Central nervous system (CNS) —where the brain, spinal cord and other structures are located— in charge of receiving, processing and sending information. Peripheral Nervous System (PNS), a network of nerve fibers in charge of receiving the stimuli and conducting the information to and from the CNS.The integration of both NSC and NSP allows an organism to fulfill all its functions, both voluntarily and involuntarily.

What is the importance of carbon?
The most common chemical element present on our Earth is carbon. It has the symbol C and an atomic number of 6. The carbon atom is a member of the fourteenth group present on the periodic table.
The word carbon is derived from the Latin word 'carbo', which means coal. Carbon is also the 15th most abundant element that is present in the crust of the Earth. On the earth, carbon is the fourth most abundant element ranked after hydrogen, helium, and oxygen.
Carbon atoms, when bonded together in different ways, are called as allotropes of carbon. Diamond, graphite, and amorphous carbon are the three allotropes of carbon.
They have different properties. Graphite is one of the softest known substances while diamond is the hardest known substance.
