Answer:
The block o time in the geological time scale are called:
Eon: The biggest ones
Eras: Which are the middle ones
Periods: Which are the smallest ones.
Explanation:
The geological time scale classifies the lapses of time in different gradients. It does it like that to optimize the retrieval of data and locate the objects and phenomenons of study to analyze them and conduct the research in an organized way. Eons are classified in Archean, Proterozoic, and Phanerozoic. Eras are classified in: Early archean, middle archean, late archean, Early proterozoic, Middle proterozoic, late proterozoic, Paleozoic, Mesozoic, Cenozoic. Periods are classified in Cambrian, Ordovician, Silurian, Devonian, Mississippian, Pennsylvanian, Permian, Triassic, Jurassic, Cretaceous, Tertiary, Quaternary.
2.How does your DNA differ from a strawberries DNA? How is it similar
Answer:
1.DNA is more than 99% similar between any two people. All the differences in how we look, feel, behave and the differences in our health are due to less than 1% difference
2.In humans each of these cells have 2 copies of the DNA, but in strawberries each of these have 8 copies of the DNA that means strawberries have 4 times as many copies of DNA as humans, making it 4 times easier to see.
Explanation:
Answer:
The correct answer is a. early menopause.
Explanation:
Estrogen is the hormone that helps in the protection of bones from being lost or degraded. This hormone is released in the ovary by follicle. The level of estrogen decreases sharply when a woman reached its menopause.
This decrease in estrogen levels in females can lead to osteoporosis in women. So early menopause increases the chances of bone loss in woman and bone loss increases the chances of fractures in women. One in two women who are above 50 in America breaks a bone due to osteoporosis. Therefore the correct answer is a. early menopause.
b. sound signal
c. language
d. visual signal
Answer:
d. visual signal
Explanation:
Changing color by cephalopods ssuch as squid & octopi is a type of visual signal which helps in communication. These creatures are highly social animals and for social behavior communication is a must. So, in order to communicate effectively, they often change the colors and patterns of their skin. Initially this ability to change color was meant for camouflage but later on these animals started using this ability to communicate. The control centre of such visual signals is their brain which can manipulate thechromatophores within their body. They usually use such visual signals during courtship rituals and hunting.
B. have to pass through the G1, S, and G2 phases to prepare for division.
C. have to use binary fission to divide.
D. have to go through prophase, metaphase, anaphase, and telophase.
The right answer is C
"Binary fission" is the most common form of reproduction and cell division of prokaryotes. A cell, after replicating its genetic material, divides into 2, each part containing a copy of the genetic material and 2 new perfectly individualized cells are finally created, each having the ability to grow to the size of the parent cell of origin ... The chronology is as follows:
- replication of the bacterial chromosomal DNA and segregation into two nucleoids and cell growth phase;
- assembly of a protein ring of constriction;
- constriction of the ring associated with the wall synthesis until complete individualization of the 2 new cells.
Approximately 90 percent of the water you ingest is absorbed by the small intestine.
The small intestine absorbs about 90 percent of the water you ingest. Water absorption is driven by the concentration gradient of the water, which is higher in chyme than in epithelial cells. Thus, water moves down its concentration gradient from the chyme into cells. The remaining water is then absorbed in the colon.
