A Punnett square would help here.
Let's say (R) is dominant red and (r) is recessive red, aka yellow.
You start with F1 hybrid flowers that are all (Rr) - these are all <em>orange</em>. So when they reproduce, both parents are (Rr). When you create a Punnett square, you'll see that the results for the F2 generation are (RR), (rr), and (Rr) twice.
(RR) is red, (rr) is yellow, and (Rr) is orange, just like the F1 generation.
Answer:
The correct answer is plants have two parts life cycle spending one part of their life in diploid phase and the other part in the haploid phase,human spending their lives in diploid phase and produces gamets that are haploid.
Explanation:
There are two stages in the life cycle of plant one is gametophyte stage which is haploid and the other is sporophyte stage that is diploid.
but in case of humans the overall life cycle proceed in diploid phase and produces gamets that are haploid.
In case of human male produces haploid gamet known as sperm and the female produces haploid gamet know as ovum. The sperm and ovum fuses to form diploid zygote,
The answer is b, decrease the oxygen gas pressure
D. Cones
Cycads are basically composed of woody plants which have roots, a stem, leaves and reproductive structures called Cones. These cones differ from each other depending on the plant whether it is female or male. These cones vary from shape, size, color, etc. based on the sex of the plant.
Answer:
1. Merocrine
2. Holocrine
Explanation:
Merocrine glands are the exocrine glands that synthesize their secretions on ribosomes attached to rough ER. These secretions are packaged by the Golgi complex into the secretory vesicles and are released from the cell via exocytosis. Tear glands, salivary glands are some examples of merocrine glands.
The cells of holocrine glands do not have vesicles but accumulate a secretory product in their cytosol. The mature secretory cells rupture to release the secretory product. This results in the presence of large amounts of lipids from the plasma membrane and intracellular membranes in secretions of these glands. One example of a holocrine gland is an oil-producing gland of the skin.
