What is the main difference between bacteria and virus?
Answer:
1. An evolutionary trait that is homologous within groups of organisms (see homology) that are all descended from a common ancestor
2. Derived traits are those that just appeared (by mutation) in the most recent ancestor -- the one that gave rise to a newly formed branch.
3. A cladogram uses lines that branch off in different directions ending at a clade, a group of organisms with a last common ancestor.
4. It helps us to form a cognitive framework of understanding complexity.
5 Because it is a learned trait. For some domains, like Bacteria and Archeabacteria, DNA is transferrable
6. A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. Viruses infect all types of life forms, from animals and plants to microorganisms, including bacteria and archaea.
7 Polyhedral, Helical, Complex, Spherical

Which behavior shows a way that animals defend their territory
Answer: Territorial behaviour, in zoology, the methods by which an animal, or group of animals, protects its territory from incursions by others of its species. Territorial boundaries may be marked by sounds such as bird song, or scents such as pheromones secreted by the skin glands of many mammals.
Explanation:
Answer:
Wolves work together to chase or kill any wolves that are not in

The moray eel and grouper fish hunt together. When both hunt together, prey barely stands a chance: hide in the reef, the eel eats you; dash for open water, the grouper grabs you. Which symbiotic relationship is described above?
A. Coevolution
b. Mutualism
c. Parasitism
d. Commensalism
Answer:
We can immediately cross-out C
We can also cross-out A.
Now we have B and D. Commensalism and Mutualism. Now, commensalism is an association between two organisms in which one benefits and the other derives neither benefit nor harm.
Mutualism is the doctrine that mutual dependence is necessary to social well-being.
I would say D: Commensalism. Both fish can survive without each other.

Which of the following is a critical factor driving evolution?
Environmental conditions
Health in comparison to similar organisms
Ability to acquire food
Strength in comparison to similar organisms
All of these are equally important
all of these are equally important, what if there is an option for natural selection, natural selection would be the most important but for this it's all these are equally important.
The critical factor driving evolution is strength in comparison to similar organisms.
According to Charles Darwin, Organisms that are better able to survive in their environment live long enough to reproduce and pass on these favorable traits to their offspring leading to the perpetuation of these organisms and gradual demise of other individuals of the same species who lack these favorable traits.
This is the origin of the cliché, "survival of the fittest". Hence organisms that lack certain strengths possessed by other organisms are gradually replaced by other individuals having such strengths.

In a Hardy-Weinberg population with two alleles, A and a, that are in equilibrium, the frequency of allele a is 0.2. What is the frequency of individuals with Aa genotype? will reward brainly for best answer with explanation...please no more links or i will report
Answer:
0.42
Explanation:
To estimate the frequency of alleles in a population, we can use the
According to this equation:-
p =
q =
p + q = 1.0
(p + q)

= 1 so p

2pq = frequency of Aa
q

p+q = 1
0.3 + q = 1
q = 1 - 0.3 = 0.7
Aa = 2pq = 2* 0.3 * 0.7 = 0.42.
What do echinoid, snail, and shark tooth fossils have in common?
Answer: All have calcium made structures which restricts their degradation and decomposition.
Explanation:
Echinoids and snails have exoskeleton which is hard and made up of calcium carbonate which is the least degradable material even after death of the organisms and remains as traces and remains in the fossils. Also the shark tooth is made of dentin which is a hard calcified tissue which does not decompose very easily. It is denser and harder then the bones. It is surrounded by the enamel shell. The dentin and enamel prevent the degradation and decomposition of the shark tooth for long hence, it gets available as fossil.

Down syndrome in humans is due to ________ of the 21 st chromosome.
Answer:
Down syndrome in humans is due to ADDITIONAL, PARTIAL OR FULL COPY of the 21 st chromosome.
Explanation:
Down syndrome is a genetic disorder in which an individual has a total of 47 chromosomes instead of 46 that is, 23 pairs of chromosomes which is found in normal individuals. This occurs as a result of the presence of additional, partial or full copy of chromosome 21. There are generic variations that occurs in chromosome 21 leading to down syndrome, these include:
-->Trisomy 21 : the individual has three copies of chromosome 21 instead of two copies due to abnormal cell division that occurred during development of sperm or egg.
--> Mosaic Down syndrome: the individual has some cells with an extra copy of chromosome 21 and it's caused by abnormal cell division after fertilization.
--> Translocation down syndrome: This type of down syndrome occurs when chromosome 21 gets attached to another chromosome which occurs during or after conception.
Generally the symptoms due to the presence of this extra genetic material includes:
--> short heights
--> poor muscle development
--> short neck
--> short fingers with small hands and feet
--> increased risk to development of dementia
--> greater tendency to develop obesity

Hope this helps ^^
Diurnal means awake during the day time, and use the light to their advantage. Nocturnal means active at night time. Thus, the correct options will be A and B.
What is Diurnal and Nocturnal?Based on the activeness of an organism during a day or 24 hours time period, the animals or organisms can be classified into two different types which are nocturnal and diurnal organisms. Nocturnal animals are the animals which are most active during the night time, and diurnal animals are the animals which are active during the daytime.
Diurnal animals are those animals which are awake during the day time, and use the light energy to their advantage. Nocturnal animals are the animals which are active at the night time.
Therefore, the correct options will be A and B.
