D. (a < b) and (a < c)
E. (a > b) and (b > c)
Answer:
The correct answer is - D. (a < b) and (a < c)
Explanation:
The persistent length of actin filaments, a bundle of cross-linked actin filaments and microtubules can be compared on their typical persistent length.
The persistent length of actin filaments is 15 µm. And due to the crosslink with one another to make a bundle their length reduced As the actin filaments cross-link each other their persistent length will be reduced. however, it is still longer than single actin filament around 20 nm.
The persistent length of microtubules is 6mm.
So b > a, a < b and a < c.
So fourth option a < c and b > a is the correct answer.
Some cells live for years, while others live for only a few days. Why do some cells get replaced faster than others?
Answer:
Some cells don't divide and last you a life time such as many of those in the central nervous system other cells such as stems called cell populations have their telemeres repeatedly extended by the enzyme telomerase other cells are never replaced and live as long as we do .

Which of the following correctly orders the steps in liquid waste excretion?
A. Kidneys > Urethra > Urinary Bladder > Ureters
B. Kidneys > Ureters > Urinary Bladder > Urethra
C. Urethra > Urinary Bladder > Kidneys > Ureters
D. Ureters > Kidneys > Urinary Bladder > Urethra
Answer:
B. Kidneys > Ureters > Urinary Bladder > Urethra
Explanation:
PENN
The correct order in which liquid waste excretion, starting from the kidneys takes place is kidneys >Ureters >Urinary Bladder >Urethra. So, the correct option is B.
What is the process of liquid waste excretion?The blood from various organs reaches the kidneys and is filtered there. The kidneys contain over a million very tiny structures known as nephrons. These are the designated regions of blood filtration. These nephrons are made of a glomerulus with a number of blood capillaries.
This process results in the formation of concentrated urine after glomerular filtration, reabsorption and secretion.
The secreted urine reaches the Urinary bladder through the Ureters connected to each of the kidneys. The Urinary bladder helps in storing the urine until it can be removed from the body through the urethra.
When the Urinary bladder is full, it creates something called the micturition reflex which creates the desire to expel urine. The urethral region is under voluntary control which means that a person can postpone performing the act of urination until they are in an acceptable position to do so.
Therefore, the correct option is B.

Most of the oxygen in the atmosphere is made by algae. Where do most of the algae live?
coastal ocean
deep ocean
ponds
lakes
Most of the oxygen in the atmosphere is made by algae, with coastal oceans housing the majority of algae. Hence the correct option is A.
What is Algae?Algae is defined as a member of a group of primarily aquatic photosynthetic organisms of the Protista kingdom. Algae is described as floating green matter on the surface of a pond, lake, river, still water, moist soil, stones that grow on wet surfaces. Therefore, they can synthesize their own food. They are found in water or in very moist places.
Algae play many important and beneficial roles in freshwater environments producing oxygen and consuming carbon dioxide that act as the base of the aquatic food chain, removing nutrients and pollutants from the water and stabilize sediments. Most of the oxygen in the atmosphere is made by algae, with coastal oceans housing the majority of algae.
Hence the correct option is A.

Explain how meiosis results in UNIQUE cells.
Meiosis is a reduction division in which the number of chromosomes in the parent cells is halved to the daughter cells.
Meiosis is the process such as:
Meiosis occurs in the reproductive cells of humans. Meiosis transmits genetic information from parent to offspring. Meiosis is the characteristic feature of sexual reproduction. The male and female gamete fuse to give rise to a newly formed combination of the daughter cells.Meiosis results in the recombination of male and female gametes, which results in the independent assortment of the genes.
Thus, meiosis always results in new variations and creates genetic diversity.

Suppose all the alleles on on the left and right chromosomes switched places but kept the same order. Would the organism be different? Why or Why not?
Answer:
No
Explanation:
The chromosome will stay the same organism.
The organism would be same in both homogenous and heterogenous chromosome . Therefore, switching the alleles won't change the organism if order is maintained.
What is chromosome and its type ?The thread-like chromosomes that convey the genomic information from cell to cell are formed of protein and a single DNA molecule. Chromosomes are found in the nucleus of cells in both plants and animals, including humans.
An organism is said to be homozygous if it has identical genes on both chromosomes. It is referred to as heterozygous if the organism possesses two distinct alleles of the gene.
Therefore, if the alleles switched places but the order remains same then organism will be same too in case of homologus as well as heterologus chromosome.

The lac operon controls the transcription of a group of genes involved in metabolizing lactose in E. coli. A group of scientists tested how to activate the lac operon. In four different mediums, they varied whether glucose or lactose was present in the medium, as indicated by a or -.The scientist discovered that the lac operon is inducible, repressed by glucose and induced by allolactose. Which medium has the right conditions to metabolize lactose
Answer:
The correct answer would be - medium with lactose present and glucose absent.
Explanation:
There are genes present in lac operon that takes part in the lactose metabolism. These genes expressed only if a medium has lactose in absence of glucose.
In the absence of glucose and lactose is present, due to inducer the lac repressor is removed from the operator. This leads to the binding of CAMP to DNA as the CAMP levels are high. It helps in high transcription levels b binding RNA polymerase to promotor.

How does an increase in atmospheric carbon dioxide effect the oceans?
Choose all that apply
-It causes them to dry-up and shrink in size.
-It causes sea levels to rise.
-It causes them to be more acidic.
-it causes them to be warmer.
Explanation:
Definitely global warming is correct because global warming is a slow process, a few degrees in hundreds of years. Moreover, there are multiple sources (causes) responsible for Earth warming. Though the Earth warms up very slowly (incomparably slower than heating a pot of water on the stove, where the heating source is only one), it occurs much faster than thousands of years ago.
An increase in atmospheric carbon dioxide is that the level of carbon dioxide is getting increased and the level of global warming is getting increased.
What is the pollution ?The pollution is the unwanted wastes that are coming out in the nature and the environment such that the level of increasing bad effects of air are increased.
It causes them to dry-up and shrink in size. It is because of the increased temperature that increases most importantly this condition of drying up and all. The sea level is increased when there is increase in water level due to the maximum water melting from glaciers that cause the water to increase in oceans.
Global warming is the intact reason that sounds so relevant to the situation where the condition is like that the increasing water will automatically level up other concerns as well that is because of the green house gases.
