How much time do cells spend in telophase and why?
Answer:
We find that in a 24-hour period, the cells we observed spend 1000.2 minutes in interphase, 180 minutes in prophase, 128.2 minutes in metaphase, 77.8 minutes in anaphase, and 51.8 minutes in telophase. As you can see, cells spend most of their time in interphase, which is expected since this makes up most of the cell cycle!

how far does a car travel in 0.75 h if it's moving at a constant speed of 88 km/h
Answer:
Distance = 66 kilometers
Explanation:
Given the following data;
Time = 0.75 hour
Speed = 88 km/h
To find the distance traveled by the car;
Distance = speed * time
Substituting into the equation, we have;
Distance = 88 * 0.75
Distance = 66 kilometers.
Therefore, the car will travel a distance of 88 kilometers.

Answer:
in my opion, hygien and care for your teath is more like, brusshing your teeth three times a day if possible and also mouth wash and dont forget to floss if possible
Explanation: My explination for this is teeth are important and needed to be taken care of.
Answer:
Hygiene is a series of practices performed to preserve health.
According to the World Health Organization, "Hygiene refers to conditions and practices that help to maintain health and prevent the spread of diseases." Personal hygiene refers to maintaining the body's cleanliness.
Many people equate hygiene with 'cleanliness,' but hygiene is a broad term. It includes such personal habit choices as how frequently to take a shower or bath, wash hands, trim fingernails, wash clothes, and basically self care. It also includes attention to keeping surfaces in the home and workplace, including bathroom facilities, clean and pathogen-free. Many people know without taking care of your teeth the food would leave many bacteria and without flossing it, it can lead to the food between your teeth to get bad causing a cavity, then tooth decay.
Good luck.

A lone wolf travels hundreds of miles from his original pack and joins a new pack in a different range, affecting the gene pool through which mechanism?
A. genetic drift
B. recombination of alleles
C. gene flow
D. no effect
Answer:
a. genetic drift
A lone wolf travels hundreds of miles from his original pack and joins a new pack in a different range, affecting the gene pool through genetic drift. The correct option is A.
What is genetic drift?
Genetic variety and genetic drift are two of the factors of evolution that are both random processes. Allelic drift, also known as genetic drift, is the change in allele frequency that is most frequently observed in small populations.
Due to random sampling, some alleles in a small population may be lost because of the low allele frequency in a small population. As a result, the population's genetic diversity declines.
Gene flow is the transfer of genes or alleles from a population that resides in one location to a population that resides in another. The movement of various alleles into a new population, it raises genetic variation.
Therefore, the correct option is A. genetic drift.

O When blood sugar concentration is too low, the endocrine system secretes hormones that increase blood sugar concentration to a normal level.
O When the body senses that the heart rate is very high, it secretes hormones that decrease the heart rate.
O When blood sugar concentration is too high, the endocrine system secretes hormones that decrease blood sugar concentration to a normal level.
O When someone is exercising intensely, the body secretes hormones that increase oxygen supply for cellular respiration.
Answer:
the answer is A when blood sugar contraction is to low
Explanation:
i took the test
The statement that describes a positive feedback loop is as follows: when blood sugar concentration is too low, the endocrine system secretes hormones that increase blood sugar concentration to a normal level.
What is positive feedback loop?A positive feedback loop is a feedback loop that occurs in nature when the product of a reaction leads to an increase in that reaction.
A negative feedback loop, on the other hand, occurs when increased output from the system inhibits future production by the system.
Therefore, the statement that describes a positive feedback loop is as follows: when blood sugar concentration is too low, the endocrine system secretes hormones that increase blood sugar concentration to a normal level.

how does spirogyra survive in a dry pond?
Answer:
I had a long answer that I would have loved to share but I can't because brainly does not like the words using and there is no way around it, tried using every synonym on the internet... LOL sorry
Spirogyra tends to grow in water in the spring, but when there is enough sunlight and warmth, it produces large quantities of oxygen, which adheres as bubbles between the tangled filaments. The filamentous masses reach the surface and appear as slimy green mats.
What are spirogyra?Spirogyra is free-floating green algae discovered in freshwater environments worldwide.
Spirogyras are filamentous algae with thin linear polymer chains of cylindrical cells that are named after their beautiful spiral chloroplasts.
Spirogyra is prized for human consumption in so many Asian countries and is recognized as an essential component of natural bioactive compounds used for antibiotic, antiviral, antioxidant, anti-inflammatory, and many more purposes.
In the spring, Spirogyra grows in water, but if it has enough sunlight and coziness, it produces large amounts of oxygen, which abides as bubbles seen between tangled filaments.
When the filamentous masses reach the surface, they form slimy green mats.
In a dry pond, using cell wall, it can survive and can get revive as the rain renew the pond.
Thus, this way spirogyra survive in a dry pond.
