Down syndrome in humans is due to ________ of the 21 st chromosome.

Answers

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

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​

Answers

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.

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.

In bacterial communities, where resources are often limited, survival requires the ability to sense, respond to, and cooperate or compete with neighboring organisms.

a. True
b. False

Answers

Answer:

Explanation:

True.

In bacterial communities, where resources are often limited, survival requires the ability to sense, respond to, and cooperate or compete with neighboring organisms is a true statement.

What are Bacterial communities?

Bacterial communities differ in their species makeup, the niches they occupy, and the effects they have on various ecosystems.

Communities defy a single, fundamental definition due to their complexity. Instead, they offer fascinating illustrations of dynamic processes that vary with ecological size. In the beginning of microbiology, there were difficulties in describing and classifying communities.

Robert Koch revolutionized the study of microbiology in the late 1800s by inventing his techniques for proving the link between an infection and an organism (Koch, 1876). Koch's hypotheses continue to be the "gold standard" for linking germs to illness or any other interesting event.

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.

Incomplete dominance, only one allele in the genotype is seen in the phenotype. In simple dominance, both alleles in the genotype are seen in the phenotype. In incomplete dominance, a mixture of the alleles in the genotype is seen in the phenotype.
