Estrogen :thickens the endometrium,inhibits the action of FSH & LH
Progesterone :thickens the endometrium ,inhibits the action of LSH&LH in the luteal phase and stimulated LH secretion in follicular phase

Uterus lining (endometrium ) thickens during the proliferative phase of the cycle due to progesterone,if there’s no pregnancy the level of progesterone and estrogen decreases (due to breakdown of corpus luteum ) hence resulting into degeneration of the endometrium (Ischemic phase )

Answer:

Estrogen and Progestrone harmone help in the thickening of the inner wall of the uterus i.e. endometrium layer,for the reception of fertilized eggs and their development.

Progestrone prepares the uterus for a fertilizef egg to implant.

The uterus lining sheds if no fertilization occured because the sperm passes through the uterus so.the lining of the uterus again starts to break down and shed ,and new mestural period begins

Quién propuso el primer mecanismo de herencia a partir de la observación y la experimentación con plantas?
marusya05 [52]

Answer:

Gregor Mendel

Explanation:

Gregor Mendel fue un naturalista, biogista y matemático que demostró por primera vez los principios de la herencia utilizando su trabajo sobre las plantas de guisantes.

Publicó su trabajo en "Experiments in Plant Hybridization" en el año 1866. Al controlar la polinización, Mendel pudo cruzar plantas de guisantes con diferentes formas de rasgos. En el primer conjunto de experimentos de Mendel, experimentó con solo una característica a la vez. Los resultados de este conjunto de experimentos llevaron a la primera ley de herencia de Mendel llamada ley de segregación (Bio Libretexts).

hichkok12 [17]

Answer:

a.  occurs right before the best growing season

Explanation:

Seed dormancy prevents seeds from germinating in unsuitable conditions such as competing for light and water with other plants or being able to be eaten from a high population of herbivores species during certain seasons.

If a dormant seed is broken after prolonged cold treatment, then this cold part of the year occurs right before the best growing season for this dormant seed. The native habitat of the plant must have an undetermined and cold season that breaks seed dormancy.

zzz [600]

Answer:

Social issues such as poverty and to fulfill basic needs etc.

Explanation:

Social issues such as poverty, lack of awareness and to fulfill basic needs etc affected the problem or its solution in the stories i.e. "Using forests wisely"  and "Community conservation" because these issues forced people to cut the forest and use the lands unwisely to fulfill their basic needs and betters their social status in the society. Due to poverty, people cut the trees in the forest and sold them to earn money in order to buy food and other necessary items for their family. If these social issues are solved, there is no need for cutting of trees and land use.

Match the following items. 1. insertion inner, light-sensitive layer of the eye 2. sympathetic system point where a muscle is at
Sergeu [11.5K]

Answer:

1. Inner, light-sensitive layer of the eye. Retina

2. Point where a muscle is attached to the more movable part. Insertion

3. Outer, fibrous layer of the eye. Sclera  

4. Translates sound vibrations into nervous impulse. Cochlea

5. Prepares the body for activity. Sympathetic system

6. Sense of balance. Semicircular canals

7. Coordinates our muscular movements. Cerebellum

8. Point where the muscle is attached to the less movable bone. Origin

9. Active when the body is resting. Parasympathetic system

10. In the brain stem, controls the activity of internal organs. Medulla oblongata

Explanation:

  • The retina is the internal layer of the eye. It receives the light from the exterior and transforms these stimuli into nervous stimuli, which travels to the brain to give an image.
  • The sclera is the outer layer of the eye. It protects the eye and keeps the eye's shape.
  • A muscle has an origin and an insertion. The first one is the part attached to the less movable bone and the second one to the more movable part. These two parts can be in different bones. When the muscle contracts, the bone attached to the insertion moves towards the origin of the muscle.
  • The cochlea and the semicircular canals are in the inner ear. The cochlea is the organ responsible for transforming the sound's vibrations into nerve impulses that will travel to the brain so that we can hear. In its interior, there are cells that have hairs, which move with the vibrations and transmit this message to the nervous system.

The semicircular canals are three and with liquid that moves as we move. The movement of this liquid moves hair cells that are in the canals. These hair cells inform our brain about our location in space and give us a sense of valance.

  • The cerebellum is part of the central nervous system. It involves the coordination of movements, learning new movements, and controlling them.
  • The sympathetic and parasympathetic nervous systems are part of the autonomic nervous system. The first one prepares our body for an emergency or an activity. It is the one that increases our respiratory frequency, our heart rate, dilates our pupils, makes us more alert, amongst other things. On the other hand, the parasympathetic system relaxes our body, slowing our heart rate, is involved in the digestion and the relaxation of our muscles. It activates, for example, after we eat.
  • The medulla oblongata is part of the brainstem. It controls involuntary actions such as heart rate, respiration, and vasoconstriction. As it controls these functions, it affects internal organs like the heart, lungs, arteries, etc.
