Into which structure is a human oocyte released upon ovulation?view available hint(s)into which structure is a human oocyte rele
devlian [24]
The correct answer is oviduct.

<span>When oocyte (female gamete) is released from the ovary during the ovulation, it travels down the fallopian tube (uterine tubes or oviduct) into the uterus, where it may become fertilised by a sperm. If fertilisation does not occur, the uterine wall and blood will be shed during menstruation.</span>

Incomplete dominance
Westkost [7]

Answer:

D

Explanation:

Incomplete dominance is a phenomenon in genetic inheritance that occurs when the two alleles of a gene seem equally effective in their influence on a trait. It is a form of Intermediate dominance in which one allele for a specific trait does not completely mask the expression of its paired allele, as opposed to Mendel's law of dominance. Incomplete dominance results in a third phenotype different from the parent phenotypes but a combination of both.

In incomplete dominance, the intermediate/resulting phenotype is the heterozygous genotype.

Gregor Mendel discovered this concept of incomplete dominance in the flower of four o'clock plants when he crossed a purebred (homozygous) red-flowered (RR) with a purebred (homozygous) white-flowered plant (rr) to get F1 offsprings that are all heterozygous but have pink flowers (Rr). He later self-fertilized the F1 offsprings to produce a phenotypic ratio of 1:2:1 consisting of 1 red, 2 pinks, 1 white flower respectively.

This showed that the allele for red flower (R) is incompletely dominant over the allele for white flower (r), hence, producing an offspring with a different trait that arose from the blending of the two phenotypes.

Incomplete dominance is similar but different from co-dominance in the sense that, in co-dominance, both alleles/traits are expressed completely in the new phenotype produced while in incomplete dominance, the new phenotype is just a blending of the two phenotypes.

In plant roots, the Casparian strip _ Group of answer choices (A) aids in the uptake of nutrients; (B) provides energy for the a
swat32

Answer:

Option-D

Explanation:

Casparian strips are the strips or band composed of a hydrophobic substance called the suberin which forms the ring-like structure in the endodermis of the vascular plants.

The Casparian strips are present around the vascular bundles in the endodermis to allow the uptake of the selective nutrients as the substance has to pass through the cell membrane before it enters the centre of the root or stele or vascular bundles.

The Casparian strips allow the movement of a substance through symplast mode only, therefore, is ensures the substance to pass through the cell membrane.

Thus, Option-D is correct.
