Answer: The follicle assumes a new role which is:
--> the secretion of hormone PROGESTERONE and
--> OESTROGEN
Explanation:
The cycle in the female reproductive system of humans which tak s 28dayd to complete is known as menstrual cycle. At the beginning of the menstrual cycle, several primary oocytes begin to develop. Each oocyte is surrounded by actively dividing granular cells from which it receives nutrients. The whole structure is called a FOLLICLE.
A developing follicle secretes OESTROGEN.
Usually, only one of the developing follicles becomes mature to produce an ovum. As the follicle matures, it becomes filled with fluid and the oocyte is pushed to one side. Ovulation occur when there is release of an ovum from a mature follicle.
The ruptured mature follicle develops into a CORPUS LUTEUM which is a solid yellow body that secretes the hormone PROGESTERONE. This is the hormone that helps to maintain the early stages of pregnancy if fertilization and implantation of embryo occurs. In the absence of pregnancy, the corpus luteum shrivels.
In a female, several main oocytes begin to mature at the start of the menstrual cycle. Each of the oocyte is surrounded by granular cells that are actively dividing and provide it with nourishment forming a ball like mass structure. This structure is known as a follicle.
After the release of a mature oocyte from the ovary, the follicle it was released from takes on a new role and becomes the Corpus luteum.
The ruptured mature follicle after releasing the one main oocyte that develops into the egg develops into a Corpus Luteum. This structure functions in the secretion of the hormone known as progesterone.
If fertilization and embryo implantation occur, this hormone helps to maintain the early stages of pregnancy. The corpus luteum shrinks in the absence of pregnancy.

Passive membrane transport processes include ________. movement of a substance down its concentration gradient movement of water from an area of low concentration to an area of high concentration consumption of ATP the use of transport proteins when moving substances from areas of low to high concentration
Answer:
movement of a substance down its concentration gradient
Explanation:
As you may already know, the plasma membrane of a cell has a semi-impermeable nature. This means that the plasma membrane allows only a few very specific substances to pass in and out of the cell. This movement of subtlety can happen in a passive or active way. In an active way, the moment is made through proteins of the membranes. Passively, the movement is made through a concentration gradient, where the substance is able to pass from the more concentrated side to the less concentrated side.

Explain how the central nervous system and the peripheral system work together to keep the body activities in balance.
Answer:
Voluntary motions in the skin, bones, joints, and skeletal muscles are controlled by the somatic nervous system. Both of these PNS systems collaborate with the CNS to control physiological functions and offer responses to external stimuli.
Explanation:
The central nervous system and peripheral nervous system work together as the nerves of PNS comes out from CNS and the peripheral nervous system guide the brain and spinal cord to receive signals from the body to work.
What is the nervous system?The nervous system is divided into two parts, the central nervous system, and the peripheral nervous system. The central nervous system consists of the brain and spinal cord. The peripheral nervous system contains all the nerves which came out from the brain and spinal cord.
Both systems work together as the nerves of the PNS connected with the brain and spinal cord. The nerves signal the brain and brain when giving signals, they travel through the nerves to the body.
Thus, together, the central nervous system and peripheral nervous system control how the brain and spinal cord receive signals from the body to function. The central nervous system sends PNS nerves out from the spinal cord.

in the fermentation experiment using yeast with the different sugars what was the dependent variable
Answer:
The dependent variable is fermentation rate.
Explanation:
When finding dependent variable phrase it like this:
______ depends on _____.
Where the first blank is the dependent variable and the second blank is the independent variable. For example, if I were to test the effects of pH on an enzyme, I would say the function of the enzyme depends on the pH level. This makes the function of the enzyme the dependent variable.

Answer: C
Explanation: I just did it on usa test perp
The transmission electron microscope requires that specimens be put inside a vacuum chamber so the microscope cannot be used to observe living specimens. The correct option is C.
What is electron microscope?The technique of electron microscopy (EM) is used to obtain high-resolution images of biological and non-biological specimens.
In biomedical research, it is used to investigate the detailed structure of tissues, cells, organelles, and macromolecular complexes.
An electron microscope can only be used in a high vacuum. This makes using a microscope to study living organisms impossible because they would evaporate and disintegrate under such conditions.
Transmission electron microscopy is a microscopy technique in which an image is formed by passing an electron beam through a specimen. The specimen is usually an ultrathin section less than 100 nm thick or a grid suspension.
Because the transmission electron microscope requires specimens to be placed inside a vacuum chamber, it cannot be used to observe living specimens.
Thus, the correct option is C.

atmosphere is a present around the surface of the earth but it is not present around the surface of the Moon why
Answer:
tmosphere is a present around the surface of the earth but it is not present around the surface of the Moon because
This reduces the amount of gravity on the moon. Strong gravity is needed to hold an atmosphere into place. With weak gravity, gases that are emitted from the surface quickly are lost to outer space. Another reason is because the moon does not currently experience plate tectonics and geologic upwelling. Plate tectonics allows for a recycling of crust and convergence and divergence of plates occurs and this leads to volcanoes and gases escaping at the boundaries. The moon is said to be geologically dead.
In addition to the transmission electron microscope (TEM), there is another type of electron microscope that is frequently used for specific purposes when studying cells and tissues, and even whole organisms. This microscope is called a scanning electron microscope (SEM). Use your lab manual, its support resources, and/or the Internet to investigate the use of scanning electron microscopy for biological applications. After gathering this information, please answer the following question. When would it be appropriate to use the SEM rather than the TEM
Answer:
The basic difference between SEM and TEM is that TEM generates an image with the assistance of radiation that goes through the specimen, while the images generated by the SEM take place with the assistance of electrons getting released from the surface of the specimen.
SEM is primarily used to examine the composition of the surface, with the help of SEM one can study the microbes present in the ecological niche like in the lining of the gut and human skin. Due to its great depth, it is considered the electron microscope analog of a stereo light microscope. It helps in providing complete images of the cells present on the surface, which are not easy to get with the help of TEM. Due to its enhanced functionality, it can also be used for size determination and particle counting, and also for process control.
