There is a supply of undeveloped eggs in the ovaries. At the beginning of the menstrual cycle, between 6 and 12 undeveloped eggs in the ovaries start to mature. A layer of cells grows around them. At around day 5 of the menstrual cycle, the biggest follicle will continue to grow for another week. At around day 14, the follicle breaks apart, and the wall of the ovary ruptures. The egg is released from the ovary into the fallopian tube, where it can get fertilized. This process is called ovulation. The uterus also changes during the course of the menstrual cycle. It has a lining of cells on the inside, kind of like a cushion with a lot of blood vessels. Fallopian tubes connect the ovaries and the uterus. The uterine cycle begins with menstruation. This is the process through which most of the lining and blood from the last uterine cycle are cleared out of the uterus to prepare for a new attempt at pregnancy. Starting at around day 5, the lining starts to grow. It builds back up to prepare a place for the egg to grow if it gets fertilized. After ovulation, the egg reaches the oviduct. If sperm cells have entered the vagina during intercourse, fertilization may occur at any time in the next two weeks. Then the fertilized egg will move into the uterus and implant itself into the lining, where development will begin.

The events in the menstrual cycle are primarily triggered by hormonal signals from the body. The menstrual cycle is a complex process regulated by the interplay of hormones produced by the hypothalamus, pituitary gland, and ovaries.
1. Hypothalamus: The hypothalamus, a region of the brain, releases gonadotropin-releasing hormone (GnRH) in a pulsatile manner. GnRH stimulates the pituitary gland.
2. Pituitary gland: In response to GnRH, the pituitary gland secretes two important hormones: follicle-stimulating hormone (FSH) and luteinizing hormone (LH).
3. Follicular phase: At the beginning of the menstrual cycle, FSH stimulates the growth and maturation of ovarian follicles, which contain the developing eggs (oocytes).
As the follicles grow, they produce estrogen, a hormone that helps prepare the uterus for a possible pregnancy.
4. Ovulation: As the estrogen levels rise, it triggers a surge in LH production by the pituitary gland. The LH surge leads to the release of a mature egg from the ovary, a process called ovulation.
5. Luteal phase: After ovulation, the ruptured follicle in the ovary transforms into a structure called the corpus luteum. The corpus luteum produces progesterone, which prepares the uterus for potential implantation of a fertilized egg.
6. Menstruation: If pregnancy does not occur, the levels of estrogen and progesterone decline. This drop in hormone levels triggers the shedding of the uterine lining, resulting in menstrual bleeding.

An object in motion tends to stay in motion and an object at rest tends to
stay at rest unless an outside force act on it is called
Kinetic energy
Potential energy
Newton's First Law
Acceleration
Answer:
Newton's first law
Explanation:
The focus of Lesson 1 is Newton's first law of motion - sometimes referred to as the law of inertia. An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Your teacher gives you a task in science class. You must decide which of the five samples you are given are alive or were once alive. One specimen is a crust gray-green object. What is the BEST clue you could use to decide: living thing or not a living thing.
A) Does it move?
B) Does it have DNA?
C) Is it made of cells?
D) Can it make its own food?
The best clue that can be used to decide living thing or not a living thing is the observation of living or dead cells present in the specimen. All the living or dead organisms exhibit cells. Cell is a structural and functional unit of life. The growth and metabolism of living organism are dependent upon a cell. A cell in a life form exhibit organelles and components which are not found in non-living objects
The BEST clue you could use to decide: living thing or not a living thing- is option C. is it made of cells and
The living things have some basic characteristic features of life in them that help in determining if an object or thing is living or nonliving thing. these characteristic can be present in all or some, are as follows:
Cellular organization - made of cell is very basic trait of life of every living being.the ability to reproduce - it is present in almost every living thing it could be sexual or asexual.growth & development - living things grow and developenergy use - use energy to perform various functionshomeostasis - regulate according the environmentGenetic material : it can have DNA as genetic materialthus, there is two options only that present in every living organism that are made of cells and presence of DNA, but for DNA one need to investigate thoroughly so the correct answer is - C) Is it made of cells?

During glycolysis, the molecule glucose is broken down into pyruvate. What type of reaction is this?
Explanation:
Glycolysis is a set of anaerobic reactions, ones that does not need oxygen to be performed. It takes glucose and breaks it down into pyruvate. This has the result of creating two ATP, which can release energy.
Overall, this process creates four ATP, but it uses two ATP early in the reaction. This means that there is a net gain of two ATP.
The overall equation for this pathway is:
1 glucose + 2 ATP ⟶ 2 pyruvate + 2 NADH + 4 ATP + 2 H2O

Explanation:
Describe the connection between limiting factors and invasive spicies
Answer: factors that limit a population size are limiting factors. Biotic potential is the amount of organisms that could be supported in an ecosystem if plenty of resources were available. Factors that cause a population to increase are 1)births: the number of births in a population in a certain period of time. 2) immigration: when organisms move INTO a population.
Explanation:
some examples of limiting factors are natural hazards, amount of food, amount/quality of water and air, predators deforestation.

Number 8. was colorblind just like his father: Where did the son at 8 get his allele for colorblindness?
Answer:
son 8 inherited it from her.
Explanation:
Given that Son 8's mother is a carrier of the blindness allele
Assuming that the father is colorblind due to a genetic mutation, there are a few possible scenarios for how the son inherited the allele for colorblindness.
What is genetic inheritance?Genetic inheritance is the study of how certain inherited traits are passed down from generation to generation.
Assuming the father is colorblind due to a genetic mutation, there are a few possibilities for how the son inherited the colorblind allele:
His father's colorblindness allele was passed down to his son. The son in this case inherited the mutation from his father.The mother carries the colorblindness allele, which she passed on to her son. In this case, the son inherited the mutation from his mother, who is not colorblind but carries the gene.The colorblindness mutation is present in both the mother and father, and the son received one copy from each parent. This is a less likely scenario, but it is possible if both parents carry the gene.Thus, in any of these scenarios, the son inherited the allele for colorblindness from one or both of his parents.
