2) in an egg cell the DNA from Mum and the DNA from that is mixed up rather than kept separate

3) egg cells are very large compared to the other cells

Answer:

➢ egg cells only have half the DNA of the organism.

➢ in an egg cell the DNA from mom and the DNA from dad is mixed up rather than kept separate.

➢ egg cells are very large compared to the “other cells.” Although still very small, in humans it's actually the only individual cell you can see without a microscope.

Embryo's nourishment

An embryo in the uterus gets the necessary nutrient through its connection to the placenta by the umbilical cord.

The necessary nutrients get to the embryo by diffusion from the placenta while waste materials from the embryo diffuse to the opposite side.

A network of blood vessels on the placenta makes the diffusion of nutrient/waste materials possible.

During which of the following processes would carbon most likely be required? Breaking of rocks Generation of electricity Making of glucose Running of cars.

Answers

Carbon is non-metal and is one of the constituents of atmospheric gases and is used for various purposes. It is an element needed in glucose production.

What are the uses of carbon?

Carbon is one of the major reactants of the photosynthesis process. Carbon along with the water vapours yields glucose which is a simple sugar. It is used from carbon dioxide in photosynthetic reactions.

Breaking of rocks, running cars and the generation of electricity does not need carbon necessarily. The process of breaking rock and electricity generation uses electrical and chemical forces, while the running of cars can use some carbon in their fuel structures.

Therefore, option C. making of glucose most likely requires carbon.

What happens during the carbon fixation stage of the calvin cycle.

Answers

Answer:

The Calvin cycle, light-independent reactions, bio synthetic phase, dark reactions, or photosynthetic carbon reduction (PCR) cycle of photosynthesis are the chemical reactions that convert carbon dioxide and hydrogen-carrier compounds into glucose. The Calvin cycle is present in all photosynthetic eukaryotes and also many photosynthetic bacteria. In plants, these reactions occur in the stroma, the fluid-filled region of a chloroplast outside the thylakoid membranes. These reactions take the products (ATP and NADPH) of light-dependent reactions and perform further chemical processes on them. The Calvin cycle uses the chemical energy of ATP and reducing power of NADPH from the light dependent reactions to produce sugars for the plant to use. These substrates are used in a series of reduction-oxidation reactions to produce sugars in a stepwise process; there is no direct reaction that converts several molecules of CO₂ to a sugar. There are three phases to the light-independent reactions, collectively called the Calvin cycle: carboxylation, reduction reactions, and ribulose 1,5-bisphosphate (RuBP) regeneration.
