Answer:
Symbiosis and ecosystem relationship
Explanation:
Symbiosis and ecosystem interaction is depicted here.
Clown fish live along with sea anemone in a mutual relationship where both the species give some benefit to each other. For instance, clown fish protect the sea anemone from predators and in return to this, the sea anemone provide food and shelter to the clown fish. Clown fish being a consumer consumes the food provided by sea anemone (producer). Hence, they form a small ecosystem while being into a symbiotic relationship also.
A concentration gradient is the process of particles or solutes moving through a solution from areas of greater particle concentration to areas of low particle concentration.
The importance of a concentration gradient is that it is what makes osmosis and diffusion to happen. If there were no gradient, there would be no movement of anything from high to low concentrations. Because cells are either hypertonic or hypotonic, nutrients and materials are able to flow either in or out of the cell and life is sustained. If all cells were isotonic, then there would be no flow of nutrients and materials and cells would not survive.
B. Human-environment interaction has to occur in a place.
C. Coordinates shows humans where a particular place is located.
D. Humans migrate or move from one place to another.
Answer:
The most appropriate answer would be A. Characteristics of “place” include things like economic activity, architecture, and culture, all of which are human elements that alter or can be influenced by the environment.
The place can be defined as the geographical area in which humans are living. Different places can have different characteristics such as economic activity, culture, architecture, employment et cetera.
These characteristics are largely influenced by the environment. For example, a natural disaster can change the financial status of any place.
These characteristics majorly determine the movement of humans from one place to another. For example, many people move to urban areas from rural areas for better opportunities, lifestyle et cetera.
Answer:
a
Explanation:
Answer:a. The hormones cause the woman's body to mimic the activities of a pregnancy and disrupt the ovarian cycle, preventing ovulation
Explanation:
Pills either as real subtance or synthetic form(Placebo) exhibit effect on ovulation ,by suppressing it thereby mimicking pregnancy.
Since ovulation is suppressed fertilization can not take place,no egg/ovum is released to be fertilized by the sperms.
The pill works by releasing estrogen and progesterone into the body. These hormones prevent ovulation and thicken the mucus plug at the cervix, making it harder for sperm to reach the egg.
The oral contraceptive pill, also known as 'the pill', contains hormones that have two main effects. The first is that they change the hormonal balance in the woman's body, making it behave as if it is already pregnant. That's because the hormones estrogen and progesterone prevent ovulation—the release of an egg from the ovaries. Without an egg to fertilize, pregnancy can't occur.
The second effect is that these hormones change the lining of the womb to make it less likely to accept a fertilized egg, and they thicken the mucus plug at the cervix, making it more difficult for sperm to reach an egg in the uterus. So, the correct answers to your question are a and b.
