Which of the following accurately describes the thermocline profile along the equator?
A. Due to constant temperatures, there's no thermocline in the tropical region. .
B. The equator is susceptible to extreme storms so the thermocline changes significantly throughout the year.
C. Due to constant temperatures, there's no thermocline in the polar regions.
D. The thermocline stays relatively stable throughout the year.
Answer:
B. The equator is susceptible to extreme storms so the thermocline changes significantly throughout the year.
Explanation:
Storms occurs on that locations where there is high temperature and high temperature is only present at the equator due to direct sunlight. So we can say that maximum storms comes at and near the regions of equator. The oceans present near the equator have a warm layer known as thermocline from where water is evaporated and the intensity of storms are also increases.

Why don’t prokaryotic cells divide through mitosis?
Mitosis requires a cell membrane, and prokaryotes don’t have a cell membrane.
Mitosis and cytokinesis require cytoplasm, and prokaryotes don’t have cytoplasm.
Mitosis is division of the nucleus, and prokaryotes don’t have a nucleus.
Mitosis requires DNA and chromosomes, and prokaryotes don’t have chromosomes.
Answer:
Prokaryotes such as bacteria propagate by binary fission. ... In bacterial cells, the genome consists of a single, circular DNA chromosome; therefore, the process of cell division is simplified. Mitosis is unnecessary because there is no nucleus or multiple chromosomes. This type of cell division is called binary fission.

Suppose Maria wants to breed parakeets that are yellow with patterned feathers. However, when she bred several parakeets that were yellow with patterned feathers, she found that there were four different offspring phenotypes.
Phenotype Number
patterned yellow wings 18
solid yellow wings 6
patterned white wings 6
solid white wings 2
Number of genes and alleles?
2 genes; 2 alleles each
1 gene; 4 alleles
4 genes; 1 allele each
Which phenotypes are coded for by the same gene? Different genes are separated by semicolons?
yellow and white; patterned feathers and solid
yellow and patterned feathers; white and solid
all by the same gene
each by a separate gene
Answer:
Explanation:
First let's define a few things.
An allele is a variant form of a gene, each gene can have two or more possible alleles, one inherited from each parent. The copies, however, are not necessarily the same. When the copies of a gene differ from each other, they are known as alleles. A given gene may have multiple different alleles, though only two alleles are present at the gene’s locus in any individual. Alleles can sometimes result in different phenotypes (observable traits), with certain alleles being dominant. (overriding the traits of other alleles)
Let's make a table of our bird's alleles.
We can see from the phenotype of her bird's offspring, yellow is dominant over white, and patterned is dominant over solid.
Let's use Y for dominant yellow, w for recessive white, P for dominant pattern, and s for recessive solid. I know dominant and recessive traits usualy use the same letter with recessive traits being lower case, but in this case it makes it easier to determine phenotype.
Our parent birds are dihybrid cross which involves 2 genes coding two traits, with dominant yellow pattern both represented by PPssYYww.
So look at the chart. It has then been color coded by the traits the bird will exhibit. We have:
9 birds with Patterned Yellow Wings
3 birds with Solid Yellow Wings
3 birds with Patterned White Wings
1 bird with Solid White Wings
This is the same ratio Maria found in the phenotypes of her birds.
Now we can answer the questions:
Number of genes and alleles? We can see that there are 2 genes, one gene for pattern, and one gene for color, but there are also 2 alleles the variant of the Pattern and the variant of the color.
Which phenotypes are coded for by the same gene?
yellow and white; patterned feathers and solid - This one as you can see from the phenotype chart, and as discussed earlier, there are 2 genes, one for color, the other for pattern.
yellow and patterned feathers; white and solid
all by the same gene
each by a separate gene

The scuba diver is a living system. The scuba gear or self- contained underwater breathing apparatus, is a system of air exchange. How are these two systems interacting? What are inputs and outputs of these systems
Answer: The carbon dioxide is the output and oxygen is the input of the Scuba apparatus.
Explanation:
The scuba apparatus is a life saving apparatus used by the sea divers. It recycles the exhaled gas and removes the carbon dioxide and compensates for the utilized oxygen gas before the diver is actually supplied with the gas for the purpose of breathing in a circuit. Hence, the carbon dioxide gas is the output and the oxygen is the input.

Which statement below best summarizes the
likely effects on the carbon cycle of clear-cutting,
or removing all of the trees, in vast areas in a
forest?
A. Clear-cutting would reduce the amount of
carbon dioxide found in the atmosphere.
B. Clear-cutting would limit the amount of nitrogenfixing
bacteria in the area.
C. Clear-cutting would allow for secondary
succession of smaller plants and more carbon.
D. Clear-cutting would increase the amount of
carbon dioxide found in the atmosphere.
Answer:
D. Clear-cutting would increase the amount of carbon dioxide found in the atmosphere
Explanation:
Plants including trees are organisms that help maintain the balance of carbon in the carbon cycle. They do this via the process of PHOTOSYNTHESIS, which is the way they obtain their energy and carbon source. During photosynthesis, trees (plants) absorb carbon in form of atmospheric carbon dioxide (CO2) from the air through the STOMATA on their leaves.
CO2 is an input substance in order for photosynthesis to occur. In a case where all the trees (plants) of a forest has been clear cut or removed, there will be no organisms to directly absorb the carbon dioxide (CO2) released into the atmosphere via respiration. Hence, the amount of carbon dioxide found in the atmosphere would increase.
Answer:
D. Clear-cutting would increase the amount of
carbon dioxide found in the atmosphere.

2. Copy/paste and align the first 5 bases of all introns. Which bases are conserved near intron start ("donor site")?
Answer:
This question is incomplete
Explanation:
Introns are non-coding regions of a DNA that removed by RNA splicing prior to translation. Alignment is usually done between sequences to see and understand the identity and similarity between two or more sequences.
A region/base is said to be conserved if there is NO change in any base in that particular region. A multiple sequence alignment (MSA) can be used to align the donor sites of all the introns to see the bases that have not "changed" (and still remained in there exact position) hence conserved across all the donor sites.
NOTE: The donor site of an intron is the 5' end, thus the first five bases in the 5' end are to be used here
Which of the following is an example of an emergent property?
Answer:
When gears and other structures are assembled into a bicycle, the entire assembly can propel the rider.
Hope this helps :)
The emergent property is that cell is the basic unit of life, one or more cells combine to form organism. The correct option is A.
What is emergent property?An emergent property is a distinctive feature that an entity acquires after becoming a part of a larger system.
Emergent properties aid in the adaptation of living organisms to their surroundings and enhance their likelihood of survival.
Carrying capacities for all species in an ecosystem's biological community are an emergent phenomenon of the ecosystem in its entirety because each species' food supply is a result of what happens in other parts of the ecosystem.
In the given scenario, cells being the basic fundamental structural unit of life, is forming a complete organism. This property of cell is indicating the emergent property.
Thus, the correct option is A.

What do you feel really got the biotech industry started and how was it different from what came before it? g
Answer:
When the human being realized that he could use living beings or their derivatives to produce products of human interest on a large scale, the biotech industry started. This sector was different from what existed before it, because it used tiny elements such as proteins, bacteria and DNA, to manufacture the products.
Explanation:
As you may already know, biotechnology is the science that allows the use of living beings and their derivatives for the manufacture of biological products much needed in human daily life. Biotechnology has been used since the beginning by mankind. This can be seen in the manufacture of bread and wine, for example. However, this science only became something industrial, when the human being realized that it was advantageous to use organisms for the production of products on a large scale.
This was an industrial innovation, since until then, the industry did not use organisms and elements so small for the production of its products.
