Answer:
1: Light-dependent reactions:
Reactants: H2O, ADP, NADP
Products: O2, ATP, NADPH
Location: Thylakoid membranes of chloroplasts in cells of leaves
2: Light-independent reactions
Reactants: CO2, H2O, ATP, NADPH
Products: C6H12O6 (glucose), ADP, NADP
Location: Stroma of chloroplasts in leaf cells
Explanation:
Photosynthesis takes place in two stages:
1: Light-dependent reactions: This stage includes splitting of water in the presence of sunlight and release of electrons and oxygen gas. The electrons are channeled into the electron transport chain and result in the formation of ATP and NADPH. This stage includes photosystem I and II present in the thylakoid membrane. Hence, light-dependent reactions of photosynthesis occur in the thylakoid membrane of chloroplasts and form ATP and NADPH.
2: Light-independent reactions: Also called as Calvin cycle, the light-independent reactions use ATP and NADPH formed during light reactions of photosynthesis to fix CO2 into glucose. The enzymes of the Calvin cycle are present in the stroma of chloroplasts and hence, this stage of photosynthesis occurs in the chloroplast stroma.
Answer:
C - motion
Explanation:
The definition of motion is "the action or process of moving or being moved."
Answer:
1. D (In population genetics, gene flow is the transfer of genetic material from one population to another.)
2. C (Genetic drift may cause gene variants to disappear completely and thereby reduce genetic variation. It can also cause initially rare alleles to become much more frequent and even fixed. When there are few copies of an allele, the effect of genetic drift is larger, and when there are many copies the effect is smaller.).
3. A and also E (Individuals with inherited characteristics that allow them to best compete for limited resources will survive and have more offspring than those individuals with variations that are less able to compete. Because characteristics are inherited, these traits will be better represented in the next generation.)
4. D (Gene flow can increase fitness but if it happens in another environment, it decreases the adaptability. If alleles are advantageous, the offsprings' inheritance increases.
5. B (Mutations are the main source of alleles)
Integument (Skin) has an outer (superficial) epidermis and in inner (deep) dermis. The epidermis is a stratified, squamous epithelium which contains keratin. The dermis is a connective tissue layer, containing an outer loose areolar connective tissue and a deeper dense irregular connective tissue.
After staining endospores will be green in a parent cell.
Staining endospore is difficult as the bacteria do not allow stains to be
attach to the spore. This is why there is a need to use heat to let the main
stain which is Malachite green into the endospore.
