The right answer is D.
The first phase of photosynthesis, called the light phase, requires the illumination of the sheet. This photochemical phase corresponds to the capture of light energy by light-absorbing pigments and its conversion into chemical energy in the form of ATP. In this reaction, the photosensitive pigments ("chlorophyll b", carotene and xanthophylls) absorb and then channel the light energy to the "chlorophyll a" whose electrons are brought to a higher energy potential. In this excited state, the electrons of chlorophyll are derived to a system that extracts and stores their energy for later use in the synthesis of sugars. The result of this electron transfer is the splitting of the water molecules to give hydrogen (H) and oxygen (0) atoms. Oxygen escapes in gaseous form O2 into the atmosphere through open stomata. This whole sequence is done in a fraction of a second.
The reaction is as follows:
H2O ==> 1/2 O2 + 2e- + 2H +
Answer: Option D. They were part of the water molecules (H2O) pulled in through the roots
Explanation:
Answer:
Photosynthesis defined as the process by which plants make there own food by trapping sunlight and using carbon-dioxide and water to produce glucose as energy.
During photosynthesis oxygen is formed as raw material along with glucose after utilizing carbon-dioxide and water.
Photosynthesis process take place in two stages light-dependent and light-independent process. During the light-dependent reactions, water molecule releases an electron and oxygen and hydrogen atoms gets free. The free oxygen atom combines with another free oxygen atom and forms diatomic oxygen (O2) that released to atmosphere.
This is how oxygen enters the plants as a part of water molecules. through roots.
B. Carbohydrates diffuse across the villus epithelium and are then actively transported into blood capillaries.
C. If intact proteins are transported across the villus epithelium, an immune response may be generated.
D. Amino acid transport is linked to chloride transport.
It considered that all terrestrial plant species that exist today have evolved from Rhyniophyta (a type of spore plants, compiled by the most primitive forms of vascular). Now terrestrial plants presents by the Moss family, psilotaceae, lycopsids, class of the Horsetail, fern, gymnosperms and flowering plants. Based on the cladogram, It assumed that the ancestors of all existing plants are algae, particularly green.
d.are made of RNA
Answer:
The correct answer would be option A. It can interact and influence a trait such as eye color.
Explanation:
Three or more alternative alleles of a gene that can occupy the same locus known as multiple allele condition. However, only two of the alleles can be present.
The ABO blood group system and human eye color are examples of the multiple allele condition.
Eye color is determined by multiple genes. OCA2 and HERC2 Both are located on human chromosome 15. A common polymorphism in the HERC2 gene is accountable for the blue eye. A person with homozygous TT predicts likely to have brown eyes, while a person with 2 copies of C allele at HERC2 rs1293832 will have blue eyes.
Thus, the correct answer would be option A.
B. A technological society has a completely positive impact on the environment
C. A technological society has both a positive and negative impact on the environment
D. A technological society has a completely negative impact on the environment
Answer:
C.A technological society has both a positive and negative impact of the environment
Explanation:
- unique phylogenetic lineages.
- abiotic factors that define the community.
- amount of primary productivity.
''Unique phylogenetic lineages.'' is the correct answer.
Biodiversity is the total number of species that are present in a place.
Biodiversity helps in the measuring of variation at the species, genetic, and ecosystem level. Phylogenetic lineage shows the relationship between different biological species so we can conclude that ''Unique phylogenetic lineages.'' is the right statement.

Answer:
Unique phylogenetic lineages. (Ans. B)
Explanation:
Biodiversity: It is defined as the total species or variety of species present in a place on earth. This variety common measurement is known as species richness, it is defined as the count of species present in an area.
It is helping in to measure variation at the species, genetic, and ecosystem level. Phylogenetic lineage showing the relationship (evolutionary) between different biological species. Their phylogeny is determined by the differences and similarities in their genetic characters.
