Most Important Contraception Methods
Male Condoms: These are worn over the penis and prevent sperm from entering the vagina.
Female Condoms: These are inserted into the vagina and create a barrier to prevent sperm from reaching the cervix.
Contraceptive Patch: A small patch containing hormones that is applied to the skin once a week.
Contraceptive Injection: A progestin injection administered by a healthcare professional every three months.
Intrauterine Devices (IUDs):

Sexual reproduction is a process by which two parents of opposite sexes produce reproductive cells that fuse to form genetically diverse offspri
Sexual reproduction involves the fusion of gametes from two parents of opposite sexes.
During sexual reproduction, the male produces sperm and the female produces eggs.
Fertilization occurs when the sperm fertilizes the eggs, resulting in the formation of a fertilized egg or zygote.
The offspring resulting from sexual reproduction have genetic characteristics of both parents.
Sexual reproduction is common in many animal and plant organisms and allows for the creation of genetic diversity within a population, which in turn increases the chances of survival in changing environments and provides opportunities for adaptation and evolution.

There are several important contraception methods available to individuals who wish to prevent pregnancy. The choice of contraception method depends on factors such as personal preferences, health considerations, and individual circumstances. Here are some of the most common and effective contraception methods:
Rhizomes
Example: bamboo
Characteristics: underground stems that produce new plants at the nodes; new plants separate when mature
Luisa Alejandra Parra Ruiz - STIs
Three main types of STIs? Viral, bacterial, and ectoparasitic
Viral
Endoparasitic
In general, today's generations do not worry about the possible infections that can be avoided with these methods, but they worry more about avoiding pregnancy to avoid having children, in my opinion the fact of having children is a miracle and people should worry more about infections than to be able to have a child.
Bacterial
Tratable with antiviral drugs but cannot be cured

Bulbs
Example: tulip
Characteristics: underground structures that contain a bud and nutrients; when divided into two or more parts, each part can grow into a new plant
Treatable and curable

Fragmentation
Example: leaves that produce roots and form new plants
Characteristics: the plant is divided into parts and each part grows to form a new plant
treatable and curable with antibiotics
Herplex Virus,Type 1:
-usually causes oral herpes.
-can be transferred to genitals by hands or oral-genital contact.
*Herplex Virus, Type 2:
-painful, shallow sores and blisters of genitals.
-can be transferred to mouth through oral-genital contact.
Human Papilloma (HPV)
-Warts around genitals and anus.
- One of most common STIs, especially for 20-24 year olds.
-Can be prevented with a vaccination, but there is no cure.
Hepatits B Virus (HBV)
-Inflammation of liver.
- Jaundice.
- B, C, D transmitted sexually or through contact with blood.
Viral Infections
Human immunodeficiency virus (HIV)
- Destroys white blood cells, leaving body vulnerable.
- Transmittable through exposure to fluids.
Acquired immunodeficiency syndrome (AIDS)
- Destroys immune system, body unable to fend off disease.
Prevalece of HVI / AIDS
- Male-female sexual contact is fastest growing exposure.
- About 35 million people living with.
Bacterial Intections
Chlamydia
- Most common bacterial infection.
- Most people asymptomatic (especially women).
- Easily treated with drugs if caught in early stages.
Gonorrhea
- Highly contagious.
- Similar to chlamydia but more severe.
Syphilis
- Very easily treated during primary and secondary stages.
- Penicillin is standard treatment.
- Starts w sore and then attacks CNS.
Public Lice
- Are small insects found in genitals.
- They got their nickname because their bodies resemble small crabs.
Scabies
- It causes a lot of itching caused by a small plowing mite.
- Scabies is contagious and spreads rapidly through physical contact in homes, educational institutions, and nursing homes.
- The most common symptom of scabies is intense itching in the areas where the mites reside.

Characteristics: horizontal stems that produce roots and leaves at the nodes; new plants grow along the stolons and separate when mature
Example: strawberry
Stolons
Angiosperms (flowering plants): Angiosperms have flowers, which are reproductive structures that contain male and female sexual organs. The pollen produced by the stamens (male organs) is carried by the wind or by pollinators (such as bees, butterflies, birds, etc.) to the stigma of the carpels (female organs). There, the pollen germinates and the male reproductive cell fuses with the female reproductive cell, forming a zygote that develops into a seed.
Gymnosperms (non-flowering plants): Gymnosperms do not have flowers, but produce cones or strobili that contain reproductive organs. The male cones produce pollen, which is carried by the wind to the female cones. There, the pollen germinates and the male reproductive cell fuses with the female reproductive cell, forming a zygote that develops into a seed.

Rose (Rosa spp.): Roses are flowering plants that belong to the Rosaceae family. Its flowers have petals and sepals that protect the male and female reproductive organs.
Corn (Zea mays): Corn is an angiosperm plant that produces an inflorescence called a spike that contains separate male and female flowers.
Apple tree (Malus domestica): The apple tree is an angiosperm plant that produces flowers with five white or pink petals and a calyx at the base that protects the reproductive organs.

Pine (Pinus spp.): Pines are coniferous trees that produce separate male and female cones. The male cones produce pollen and the female cones produce ovules.
Fir (Abies spp.): Fir trees are coniferous trees that produce downward-hanging female cones and upward-growing male cones on the upper branches.
Cypress (Cupressus spp.): Cypresses are coniferous trees that produce separate male and female cones on distinct branches. The female cones are round and small, while the male cones are elongated and egg-shaped.

Human reproduction is the way in which a new baby is reproduced and born, this is formed through a process in which a man and a woman are needed, and several requirements of those for a correct process.
asexual reproduction (Isabella Gutierrez)
Asexual reproduction is that which does not need two progenitors, but allows to obtain a new organism only with the part of an old organism.
One of the advantages of asexual reproduction is that no energy is expended to find a partner, no waiting 9 months for pregnancy, and the future of the offspring is more secure. another advantage is that no sexual diseases or infections are encountered.
The disadvantages are that genetics is much more effective through sexual reproduction, and they have a lower probability of survival due to time change.
Examples:
FRAGMENTATION:
is when the parent (the old organism), breaks into different pieces, and from that piece comes out a new organism, as it usually happens with starfish.
BINARY FISSION:
is when the DNA of a cell replicates and from that new DNA another organism arises, it is found in bacteria or anemones.
GEMMATION: is that method of asexual reproduction of plants which includes a branch or a piece of the flower.

- both males and females have to produce gametes, as it is an important part of the beginning of the process.
- then comes the action part, in which the man has to insert his penis into the woman's vagina, better known as coitus.
- when they finish the act and the man ejaculates inside the woman, the sperm will be left looking for the egg, when an egg finds and penetrates one it will be called fertilization.
- The embryo begins to divide rapidly as it travels toward the uterus. During this journey, it develops into an embryo composed of several cells.
- when the embryo reaches the uterus, it attaches to the wall of the uterus and a structure called the placenta is formed and is vital for providing oxygen and nourishment to the embryo.
- the embryo begins the process of becoming a fetus.
- after 9 months or 40 weeks the fetus will be fully developed and ready for birth and life.
- and finally there will be the life of the fetus outside the breast.
