Answer:
Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma. The goal of every living organism, including plants, is to create offspring for the next generation. One of the ways that plants can produce offspring is by making seeds.
Fertilization is the process by which male and female gametes are fused together, initiating the development of a new organism.
The correct answer is option B, that is, all living organisms are composed of one or more cells, which came from pre-existing cells.
A scientific theory refers to a well-substantiated illustration of some characteristic of the natural world, on the basis of a number of facts, which have been repeatedly confirmed via the experiment and observation. Such fact-supported theories are not hypotheses, however, are reliable explanations of the real world.
During the late 1830s, the zoologist Schwann and the botanist Schleiden were examining tissues and postulated the unified cell theory. According to the unified cell theory, all the living things comprises of one or more cells, the cell is the fundamental unit of life, and the new cells originate from the pre-existing cells.
Answer:
Syphilis is a sexually transmitted disease
Explanation:
Syphilis is a sexually transmitted infection caused by <em>Treponema pallidum</em>, a spirochaete gram-negative bacterium with various subspecies. This disease is transmitted through direct contact (person to person) by different types of sexual acts. A chancre is an infectious genital lesion that is considered to be the first stage (and symptom) of syphilis. The incubation period of syphilis is 14-21 days. Syphilis can be divided into four stages: primary, secondary, latent, and tertiary. Primary syphilis produces chancres on the genitals, mouth, rectum, etc. Secondary syphilis causes rashes that occur from 2-8 weeks after the chancres. The third (latent) stage is a latent/hidden phase without noticeable symptoms. Finally, the tertiary (late) stage causes large sores within the body that affects the heart, nervous system, etc. The best manner to prevent syphilis is by practicing safe sex (e.g., by using condoms). It has been suggested that syphilis has an estimated transmission rate of 0.5–1.4% per sexual act. Syphilis doesn't have an effective treatment, but this disease can be cured in its early stages with one dose of benzathine penicillin G (administered intramuscularly).
The cup like structure, in which the femur fits into the hip bone is known as Acetabulum.
the acetabulum is referred to a concave shapoed surface of the pelvis, which have a cup like groove. This groove helps in the binding of the femur head to the hip or the pelvic bone.
The round head of the femur gets fits into this cup shaped structure and forms the hip joint. The acetabulum is formed by the contribution of ischium, ilium and the pubis.
hi there
your answer to this is :
fossil fuels are being broken down by the a natural process faster than they can it can form. Energy resources such as fossil fuels must be transported to power stations before they are be used to generate electricity to power up the place. The transportation significantly adds it up to the cost of power production.
I hope this helps out
have a great morning
