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.

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

Answer:

Cystic Fibrosis is a chronic, genetic condition that causes patients to produce thick and sticky mucus, inhibiting their respiratory, digestive, and reproductive systems. Like Thalassemia, the disease is commonly inherited at a 25 percent rate when both parents have the Cystic Fibrosis gene.

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.

Answer:

diurnal means awake during the day, and use the light to their advantage

nocturnal active at night.

Explanation: Diurnal means active during the day, such as a mosquito meanwhile, a nocturnal animal or being is only active during the night, and sleeps the day away, such as a bat

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.

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.

Answer: A mutation is a change in a DNA sequence? Mutations can result from DNA copying mistakes made during cell division, exposure to ionizing radiation, exposure to chemicals called mutagens, or infection by viruses.

Explanation:

The most common genetic mutation is, In fact, the G-T mutation.

Answer:

Cell provide structure and support to the body of an organisms

Answer: They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body's hereditary material and can make copies of themselves. Cells have many parts, each with a different function. brainliest?

Explanation:

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

To estimate the frequency of alleles in a population, we can use the  

According to this equation:-

p =

p + q = 1.0  

(p + q)

p+q = 1

0.3 + q = 1

q = 1 - 0.3 = 0.7

Aa = 2pq = 2* 0.3 * 0.7 = 0.42.
