Sia ? 4 years, 3 months ago

G6PD deficiency occurs when a person is missing or does not have enough of an enzyme called glucose-6-phosphate dehydrogenase. This enzyme helps red blood cells work properly. Too little G6PD leads to the destruction of red blood cells. This process is called hemolysis.

The name papilionatae and cruciferae is based on :-

Posted by Aahana ❄❄ 4 years, 3 months ago

CBSE > Class 12 > Biology

2 answers

Sia ? 4 years, 3 months ago

Both of the families Papillionaceae and Cruciferae are named in this way due to the characteristics of their corolla. The corolla or the petals are the portions of the plant that is present behind the calyx of the plant. This whorl is usually colored.
Papilionaceae: Another name for this family is Fabaceae. This is the pea family. The corolla of this family resembles a butterfly because of its arrangement. The name ‘papilio’ is Latin for butterfly. Therefore the name of the family is based on the shape of the corolla.
Cruciferae: Cruciform refers to a shape that is like a cross. This is the cabbage family. The flowers of this family all have four flowers that are positioned in a cross-like formation. The petals are positioned at right angles to each other which is what gives them this shape.

Define ‘oestrus’ and ‘menstrual’ cycles.

Posted by Priya Rani 4 years, 3 months ago

CBSE > Class 12 > Biology

1 answers

Sia ? 4 years, 3 months ago

Oestrous cycle	Menstrual cycle
Species with oestrous cycles, females are generally only sexually active during the estrus phase of their cycle	In contrast, females species with menstrual cycles can be sexually active at any time in their cycle even when they are not about to ovulate
The oestrous cycle occurs in reptiles	The menstrual cycle occurs in mammals
The oestrous cycle is determined by FSH hormone	The menstrual cycle is determined by LH hormone
Oestrous cycles resorb the endometrium if conception does not occur during that cycle	Animals with menstrual cycles shed the endometrium through menstruation
The oestrous cycle is the reproductive system in most mammals where reproductive hormones cause the cycles to start after puberty in sexually mature females	The menstrual cycle is the regular natural change that occurs in the female reproductive system that makes pregnancy possible

This is because a cry gene introduced by GE, produces certain crystal proteins in inactive form. As any concerned insect eat that plant, the inactive protein gets activated in the presence of alkaline ph of it's gut and binds with the midgut epithelial cells and cause swallowing and lyses when water enters into it. And the insects dies
