The graph shows the changing levels of hormones during menstruation and ovulation. What happens to hormone levels during ovulation, and why is this important?
Answer:
The estrogen level decreases during the ovulatory phase, and the progesterone level starts to increase. And it is important, because hormones that are being releazed stimulates the egg to move from the fallopian tube, which then leads to menstruation.
Explanation:
The ovulatory phase begins with a surge in luteinizing hormone and follicle-stimulating hormone levels. Luteinizing hormone stimulates egg release (ovulation), which usually occurs 16 to 32 hours after the surge begins.
Answer:
Hormone levels generally decrease.

How can you tell the stigma
from the stamens in a tubular insect-pollinated flower
Explanation:
The stigma is the sticky knob at the top of the pistil. It is attached to the long, tubelike structure called the style. The style leads to the ovary that contains the female egg cells called ovules. The male parts are called stamens and usually surround the pistil.

Some medicines are delivered in capsules or artificial vesicles to be swallowed. Would this method be best for delivering medicines that act on target protein in the plasma membrane,the mitochondria,or the cytosol?
Answer:
the cytoplasm because cytoplasmic enzymes can degrade artificial vesicles such as, for example, lipid-like vesicles. Subsequently, the drug can be delivered at specific cellular locations (including the cell membrane and mitochondria)
Explanation:
The design and development of drug delivery systems is fundamental for the efficiency of the medicine being delivered to the body. Within the cytoplasm, there are specific lytic enzymes that degrade capsules containing medicine (e.g., lipolytic enzymes capable of degrading lipid vesicles). Within the cytoplasm, the drug is delivered to target sites (in this case, the cell membrane or mitochondria) by the activation of different molecular recognition mechanisms.
How does the nucleus, cell membrane, and ribosomes work together?
Answer:
Eukaryotic cells have a true nucleus, which means the cell's DNA is surrounded by a membrane. Therefore, the nucleus houses the cell's DNA and directs the synthesis of proteins and ribosomes, the cellular organelles responsible for protein synthesis.
OR
In the nucleolus, new ribosomal RNA combines with proteins to form the subunits of the ribosome. The newly made subunits are transported out through the nuclear pores to the cytoplasm, where they can do their job.
The nucleolus inside the nucleus produces ribosome components, which are synthesized just outside of the nucleus form ribosomes.
The spindle then sends mRNA towards the ribosomes, which is used to code for protein synthesis.
Other organs in the cell, including the mitochondria and lysosomes, are surrounded by lipid membranes that isolate them from other components in the cell.

Fossils help scientists date rocks
Sometimes younger rock layers are found beneath older rock layers
The map of earth has changed over millions of years, but it is now set
No fossils from the Precambrian era have been found because there were no organisms at that time
Answer:
1. True 2. True 3. False 4. False
Explanation:
Fossils help scientist date rocks: Fossil presence is one of the most useful characteristics to date a rock, a fossil will set a specific geological age in which the organisms was present in the world, and vice-versa a new fossil can be dated by studying the age of the rock it was found. Answer: True
Sometimes younger rock layers are found beneath older rock layers: This phenomenon can be found in rock layers near the surface because process such as landslides that happen on the surface moves the surface rocks often resulting in older rocks appearing in the surface and younger rocks being buried by them. Answer: True
No fossils from the Precambrian era have been found because there were no organisms at that time: Although the number of organisms where very little organisms like algae (Stromatolites) were present in this era and fossils can be found. Answer: False
The map of Earth has changed over millions of years: but it is now set: The Earth crust is actually still moving, and will always move due to the tectonic plates and their movement caused by density and pressure, Nowadays The countries have moved from their once mapped location, because of this maps are needed to be updated by new geodesic measurements of the surface. Earth crust moves 2.5 centimeters per year. Answer: False
What is one way to reduce the use of nonrenewable energy resources?
A building additional gas-powered factories in rural areas
B making more efficient gas-powered automobiles
C burning coal instead of wood in a fireplace
D mining for coal instead of drilling for oil
One way to reduce the use of nonrenewable energy resources is that make more efficient gas-powered automobiles. Thus, the correct option is B.
What is a Non-renewable energy resource?A non-renewable energy resource may be defined as a source of natural resources that can not be readily replaced by natural means at a speed quick enough to keep up with consumption. Such types of resources take millions of years to be synthesized.
Burning of coal, mining of coal, building additional gas-powered factories in rural areas, utilization of nuclear energy, etc. are not the measures that are helpful in the reduction of usage of nonrenewable energy resources.
If we want to reduce the usage of non-renewable energy resources, it is required to be less dependent on such resources.
Therefore, one way to reduce the use of nonrenewable energy resources is that make more efficient gas-powered automobiles. Thus, the correct option is B.

Granite takes much longer to form than basalt. How will the size of the crystals in granite be different from the size of the crystals in basalt?
Answer:
The size of the crystals in granite will be different from the size of the crystals in basalt depending on how they are formed and how they are cooled which determines the nature of the crystals they produce. Granite takes a much longer time to form than basalt because granite takes a very long time to cool down since it is intrusive giving minerals to be well-formed and producing a bigger size of crystals with individual mineral grains that are can be seen without the need for bigger magnification. While basalt crystals are much smaller as the crystals form very quickly because the magma comes out of the earth and cools quickly giving rise to fine-grained minerals.
Explanation:
Granite and basalt are both igneous rocks.
Granite takes a longer time to cool as it hardens under the earth's surface causing the delay in cooling while basalt takes a shorter time to cool as it hardens above the earth's surface.

If you breathed in a lot of chlorine at the pool, which of your cells would be affected? If an embryo were exposed to chlorine, which of his cells would be affected?
Answer:
I HATE KEYONNN\
Explanation:
If a lot of chlorine is breathed in, then it would harm the lungs' cells, especially the cells of the airways, the pseudostratified epithelial cells. It harms the different organs of developing embryos as it depends on the mother.
What is breathing?Breathing is the process of taking the oxygen inside the lungs from the atmosphere and releasing the carbon dioxide into the atmosphere. If a large amount of chlorine is taken, it will affect the cells in the airways.
Long-term inhalation of such gases causes lung problems such as acute lung disorder, asthma, pulmonary pneumonia, and so on. If such a condition arises, then it would be very difficult to provide proper oxygen to the body, and many other cellular activities would be affected.
In the case of developing embryos, it depends on the maternal supply. If the maternal blood is toxicated with chlorine, then it will supply the baby, and the developing baby organs will be affected. There are many disorders such as improper development of the brain, lungs, bones, etc. It will affect the embryo's cognitive capacity too.
Hence, a lot of chlorine affects the lungs the most when breathed.
