The Sierra Nevadas are an example of a fault-block mountain range. Based on this information, which of the following processes formed the Sierra Nevadas?
Melted rock called magma rose through holes in Earth's crust and gradually solidified as it cooled.
Tectonic movement forced certain segments of Earth's crust downward and other segments upward in jagged chunks.
One tectonic plate moved beneath another plate at a subduction zone, causing the rock to melt and rise above Earth's surface.
Segments of Earth's crust bent and doubled over, and moving wind and water gradually shaped the rock into gently sloping domes.

why is mitosis a longer and more complicated process of cell division then binary fission?
A.mitosis occurs in the cytoplasm and does not require nucleus
B.mitosis has checkpoints that must be met to continue the cycle
C.binary fission produces two identical daughter cells
D.binary fission does not replicate DNA
Answers
B is the only one thats logical
Mitosis is a longer and more complicated process than Binary fission because : ( B ) Mitosis has checkpoints that must be met to continue the cycle.
The process of mitosis is longer than binary fission due to the absence of spindle formation and sister chromatids in the process of binary fission.
Mitosis and binary fission are both means of asexual reproduction occurring in organisms. Mitosis occurs in eukaryotic organisms while Binary fission occurs in prokaryotic organisms.
Both process produces two identical daughter cells and they both replicate DNA in each of the daughter cells produced. mitosis occur in eukaryotes ( organisms with cell nucleus ) therefore mitosis requires nucleus.
Hence we can conclude that Mitosis is a longer and more complicated process than Binary fission because : ( B ) Mitosis has checkpoints that must be met to continue the cycle.

The hormone calcitonin, which is produced by the thyroid gland, helps to regulate the concentration of calcium ions in the blood by decreasing it.
Calcitonin acts on the bones by decreasing the activity of osteoclasts, cells that break down bone tissue and release calcium into the bloodstream.
As a result, less calcium is released into the bloodstream from the bones, leading to a decrease in blood calcium concentration.
This is important for maintaining homeostasis and preventing hypercalcemia, which can lead to various health problems such as kidney stones, bone pain, and muscle weakness.

In organisms other than plants, when and where is the most ATP produced?
in cytoplasm, during photosynthesis
in nuclei, during cellular respiration
in chloroplasts, during photosynthesis
in mitochondria, during cellular respiration
Answers
Answer:
D. In mitochondria, during cellular respiration.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature. A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
All living organisms such as plants and animals require energy to function properly (life activities). Thus, the organelle where energy from nutrients is released is generally referred to as mitochondria. Animals retrieve energy using mitochondria to do cellular respiration because they typically act like a digestive system by taking in nutrients, breaking them down and obtaining energy rich molecules for cell-life activities.
Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage.
Basically, mitochondria is one of the cell organelles found in all living organisms and it is known as the powerhouse. Therefore, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.
In organisms other than plants, the most ATP is produced in mitochondria, during cellular respiration.

State one difference between the sperm cell and the cells in the developing fetus
Answers
Answer:
One significant difference between a sperm cell and the cells in the developing fetus is that a sperm cell is a specialized reproductive cell carrying genetic material from the father, while the cells in the developing fetus are diploid cells containing a combination of genetic material from both the mother and the father. In other words, sperm cells are haploid (containing half the usual number of chromosomes) and are involved in fertilization, while fetal cells are diploid and contribute to the development of the individual.

b. Myosin head forms cross bridge with actin
c. Myosin binding sites covered
d. Power stroke moves thin filament
e. Cross bridges detach from actin
f. Myosin head is re-energized
g. Calcium ion concentration decreases below the threshold for binding to troponin
h. ATP attaches to myosin head
Answers
Answer:
Explanation:
This is the process of muscle contraction and relaxation in the muscle. The type of muscle involved is the skeleton muscle.
The process is initiated in the Central nervous system. Examples are in contraction of biceps and triceps.
It involves myosin head and actin filament coupled with the release of calcium ion from the sarcoplasm reticulum: this ion activates this process in the muscles. With the exposure of the music binding site on the acting filament, myosin is able to bind to acting filament bringing about this process.
a. ATP attaches to myosin head
b. Myosin head is re-energized
c. Myosin head forms cross bridge with actin
d. Power stroke moves thin filament
e. Cross bridges detach from actin
f. Myosin binding sites covered
g. Calcium ions pumped into the sarcoplasmic reticulum
h. Calcium ion concentration decreases below the threshold for binding to troponin.
Muscle contraction results from the interaction between actin and myosin filament proteins.
During muscle contraction, ATP binds to myosin, which passes to a high-energy state and it allows actin and myosin to detach from each other.The sarcoplasmic reticulum (SR) is a specialized type of endoplasmic reticulum in muscle cells that acts to regulate the concentration of cytosolic calcium (Ca2+).The sequential steps are as follow:
Myosin head forms cross bridge with actinPower stroke moves thin filamentATP attaches to myosin headCross bridges detach from actinMyosin head is re-energizedCalcium ions pumped into the sarcoplasmic reticulumCalcium ion concentration decreases below the threshold for binding to troponinMyosin binding sites coveredIn conclusion, muscle contraction results from the interaction between actin and myosin filament proteins.
