Progesterone levels rise during the luteal phase of the ovarian cycle and the secretory phase of the uterine cycle. Menstruation occurs just after LH and FSH levels peak. Menstruation occurs after progesterone levels drop. Estrogen levels rise before ovulation, while progesterone levels rise after.
Which phrase describes transmutation?(1 point) the conversion of protons to neutrons through nuclear changes the conversion of one substance to another through chemical changes the conversion of an atom of one element into a different element through nuclear changes the conversion of energy to matter through chemical changes
Answer:
B
Explanation:
PLEASE MARK AS BRAINLIEST!!!!!Transmutation is conversion of an atom of one element into different element through nuclear changes.
Transmutation consists of the conversion of stable nuclei into other nuclei if they are bombarded by fast particles.
Specifically, an atom can be transmuted by making particles or atoms collide with it at high speed, that is, to accelerate a particle is to increase its speed by some mechanism that imparts energy to it.
Thus, the transmutation of an element requires that there be a change within its nucleus, and in particular in the number of protons.
The neutrons or protons must have enough energy to overcome the nuclear forces that prevent their passage or exit from the nucleus of the atom to be transmuted.
Therefore, we can conclude that transmutation is conversion of an atom of one element into different element through nuclear changes.

What would be the speed of a wave with low tension, a distance of 8.5 cm and a time of 3.25 seconds?
The speed of the wave will be 0.026 m/s
The speed of a wave is the distance traveled by a given point on the wave (such as a crest or trough) in a given interval of time.
Speed is given by the formula
[tex]Speed = \frac{Distance}{Time}[/tex]
From the question,
Distance = 8.5 cm
First, convert this to meter
Recall:
100cm = 1m
∴ [tex]8.5 cm = \frac{8.5}{100}[/tex] m
8.5 cm = 0.085m
and
Time = 3.25 seconds
Now, putting the above parameters into the equation
[tex]Speed = \frac{Distance}{Time}[/tex]
∴ [tex]Speed = \frac{0.085}{3.25}[/tex]
Speed = 0.026 m/s
Hence, the speed of the wave will be 0.026 m/s

how does the loss of species affect the entire ecosystem
Answer:
Declining biodiversity lowers an ecosystem's productivity (the amount of food energy that is converted into the biomass) and lowers the quality of the ecosystem's services (which often include maintaining the soil, purifying water that runs through it, and supplying food and shade, etc.).
Answer:
"When a species becomes extinct, they reduce the variety of animals, plants, or bird species from that ecosystem resulting in the extinction of the other species that were dependent on them. Different species are playing different roles in the ecosystem to maintain a balance of the world." Credits to outside sources that it won't let me say :(

Even in case your LDL cholesterol and blood stress ranges are best mildly elevated, while they're each found in your frame, they could have interaction with every different to extra fast harm your blood vessels and your coronary heart.
What is the relationship between blood level and cholesterol?The hyperlink among excessive blood stress and excessive LDL cholesterol is going in each direction. When the frame cannot clean LDL cholesterol from the bloodstream, that extra LDL cholesterol can deposit alongside artery walls. When arteries emerge as stiff and slender from deposits, the coronary heart has to paintings extra time to pump blood via them.

Somoene please help and explain how to read the graph!!
Answer:
Whats going on is that you have a specific amount of enzyme that can do a specific amount of work. Think of it like a hotdog stand. the enzyme would be you and your substrats are your hot dogs and buns. You can only go as fast as the materials you have. If you have more materials than hands you can only go as fast as you can make them. To many substrates and you enzyme rate will cap out at maximum speed.
Explanation:
The plot shows rate of reaction of an enzyme as a function of the concentration of substrate. At stage B, the rate flattens and becomes constant, which means there's too much substrate for the enzyme to handle. So the fourth statement is false - the rate of reaction cannot be increasing.

can anyone writet about describing ● History of Ribosomes.
Answer:
The ribosome is a complex molecule made of ribosomal RNA molecules and proteins that form a factory for protein synthesis in cells. In 1955, George E. Palade discovered ribosomes and described them as small particles in the cytoplasm that preferentially associated with the endoplasmic reticulum membrane. Along with other scientists, Palade discovered that ribosomes performed protein synthesis in cells, and he was awarded the Nobel Prize in 1974 for his work.
Each ribosome has a large component and a small component that together form a single unit composed of several ribosomal RNA molecules and dozens of proteins. The ribosome is responsible for translating encoded messages from messenger RNA molecules to synthesize proteins from amino acids. The ribosome translates each codon, or set of three nucleotides, of the mRNA template and matches it with the appropriate amino acid in a process called translation. The amino acid is provided by a transfer RNA (tRNA) molecule. Each newly translated amino acid is then added to the growing protein chain until the ribosome completes the process of protein synthesis.

which combination of cells and growth factors would serve as the control group?
Answer:
These stimuli, called growth factors, are naturally occurring proteins specific to certain groups of cells in the body. They include nerve growth factor, epidermal growth factor, and platelet-derived growth factor.
Explanation:
Hope this helps.
Growth factors are defined as the proteins that bind to specific receptors, which activate the cascade of signal transductions. The growth factors lead to proliferation, apoptosis, and development.
Different types of growth factors stimulating the signal transduction are:
1. Nerve growth factor is controlled by the gene NGF. It provides the instructions to make the beta protein, which is important for the survival and development of the nerve cell.
2. Epidermal Growth Factor is a type of factor that stimulates cell development and cell proliferation. It generally stimulates the fibroblasts and epithelial cells.
3. Platelet-derived growth factor regulates cell division and growth. These factors help in healing and repairing the wound and walls of the damaged blood vessels.
Thus, the growth factors when bound to specific cell receptors control the various activities of the cells.
