If pregnancy among women does not occur, then menstruation occurs. The menstrual cycle usually lasts about 28 days.
What do women experience during their menstrual period?During menstruation, women may experience abdominal cramps, headaches, backache, and nausea.
The stage in which a woman is most fertile is called Ovulation. During this step, an egg is released from the follicle in the ovaries.
If a fertilized egg successfully embeds itself in the uterine lining, then the woman becomes pregnant.
If the fertilized egg does not manage to embed in the uterine lining, then menstruation will occur.
The two main hormones that control the menstrual cycle are estrogen and progesterone. If the egg is not fertilized, then progesterone levels drop.
The estrogen needs to stop FSH to be produced to make sure only one egg matures in the cycle.

Answer:
taking a closer look at the natural world
Explanation:
using prior knowledge is basic common sense. so no.
requiring evidence and thinking logically is following a rule. so no.
following strict rules when using human test subjects. right off the bat, "strict rules" is an immediate no.

For the History of Classification Quick Check(2021-2022):
1. binomial nomenclature
2. domain
3. Both focus on illustrating taxonomic relationships between organisms.
4. domain, kingdom, phylum only
5. juglans nigra
In this question we will do a Biological Classification History Check.
1. Binomial nomenclatureBinomial nomenclature or binary nomenclature designates the set of rules that regulate the attribution of scientific names to species of living beings.
2. DomainIs based on molecular phylogeny data. According to Woese, there are three domains: Archaea Domain, Bacteria Domain, and Eukarya Domain.
3. Both focus on illustrating taxonomic relationships between organisms.No, binomial nomenclature is for the purpose of assigning names.
4. domain, kingdom, phylum only.No, the classification is more extensive
5. juglans nigraIt is a tree that can reach heights between 20 to 50 m. It is still a monoecious, deciduous and aromatic tree.

A father has type A blood. A mother has type AB blood. If their child has type B blood, what would the father's genotype be?
Answer:Two parents with A blood type can produce a child with either A or O blood types. Two parents with B blood type can produce a child with either B or O blood type. One parent with A and another with B can produce a child with A, B, AB or O blood types. If one parent has A and another has AB, they can either produce a child with A, B or AB blood types. If one parent has A and another has O, they can either produce a child with A or O blood types.

Two species regularly come into contact and form hybrids that have higher fitness than either of the parental species. What are some likely consequences of regular hybridization between these species
Answer:
hybridization is categorized as crossing organisms that have different traits to bring together the best of each. However, this can come with some post-zygotic barriers.
Reduced hybrid viability: hybrid offspring does not survive
Reduced hybrid fertility: hybrid offspring cannot reproduce
hybrid breakdown: first generation of hybrids are viable and fertile, however, their offspring (generation 3) are sterile.

Question 4
Which of your fossils are most likely heterotrophs? Which of them are autotrophs? How do you know?
Answer:
Fossil A: Heterotrophs
Fossil B: Autotrophs
Fossil C: Heterotrophs
Fossil D: Heterotrophs
Explanation:
I'm not 100% sure of the answer but I'll explain:
Fossil A is a heterotroph because it looks like a snail shell and snails eat other things for energy (keep in mind heterotrophs eat other things for energy while autotrophs make their own energy through the sun)
Fossil B is an autotroph because it looks like a fern which is a plant and plants use the sun for energy
Fossil C is a heterotroph because it looks like a centipede or some arthropod which eat other things for energy
Fossil D looks like a brachiopod which eats other things for energy
(If you want to fact check me you can search each of the organisms and how they get energy)
Where do preganglionic neurons synapse with postganglionic neurons in the sympathetic nervous system?.
Preganglionic axons synapse at the sympathetic chain ganglia with a postganglionic neuron. The postganglionic neuron then leaves the sympathetic chain ganglia through a gray ramus communicans (unmyelinated axons) and reenters the spinal nerve and travels to the skin and blood vessels throughout the body.
Based on the blast results, what can you conclude about your query sequence? answer the questions below by dragging one pink label to each pink target and one white label to the white target. Pink labels may be used once, more than once, or not at all.
The BLAST program (Basic Local Alignment Search Tool) was developed to perform searches and compare biological sequences against a database that contains a large amount of information.
The BLAST programThe BLAST program performs the search using segments of the query sequence against the database sequences. The query string is divided into small words (word) that will be used in the search. These substrings are compared with the subject strings until identical strings are found.
With this information, we can conclude that the BLAST program was developed to perform searches and compare biological sequences.

A mitosis inhibitor is a medication that is designed to prevent mitosis in certain cells. Why would these be helpful in the the treatment of tumors?
Answer:
This would be helpful because mitosis is the way something grows. Cells split apart and what they're inside grows bigger. So if a tumor undergoes mitosis, then it grows. That is bad.

The color of the CUI marking is white. Examples of CUI include legal documents, health documents, blueprints, intellectual property, personally identifiable information, and many other types of data.
The rule is made to make sure that every organization keeps the information safe. There are two types of CUI registry resources and they provide government-approved CUI, and they are the DoD CUI registry and the NARA CUI registry.
