In marsupials, X inactivation occurs exclusively to paternally derived chromosomes. Which genes will
ALWAYS be expressed in this situation?
A. maternal X-linked genes
B. paternal X-linked genes
C. maternal Y-linked genes
D. paternal Y-linked genes
Answer:A maternal x linked genes
Explanation:
In marsupials, X inactivation occurs exclusively to the paternally derived chromosome. The genes which are always expressed in this situation is that of maternal X linked genes (option A).
The gene that will be expressed in the situation is maternal X-linked genes. The correct option is A.
What is maternal gene?Maternal genes are those whose RNA or protein products are produced or deposited in the oocyte or are present in the fertilized egg or embryo before zygotic gene expression begins.
The phenotype of the offspring is determined by the maternal genotype. Maternal effects are frequently observed because the mother provides a specific mRNA or protein to the oocyte, and thus the maternal genome determines whether the molecule is functional.
X inactivation occurs only on the paternally derived chromosome in marsupials. Maternal X linked genes are the only ones that are always expressed in this situation.
Thus, the correct option is A.

All of the following are TRUE statements about prokaryotes EXCEPT:
A - Some prokaryotes can live in extreme habitats.
B - Prokaryotes are the most important photosynthesizers.
C - Some prokaryotes are important as decomposers.
D - Prokaryotes dominate the biosphere
E - Prokaryotes are the most numerous organisms on earth
Answer:
B - Prokaryotes are the most important photosynthesizers.
Explanation:
There are some phototrophic prokaryotic organisms such as cyanobacteria and photosynthetic bacteria that carry out photosynthesis through chlorophyll-like pigments (bacteriochlorophylls) that enable them to absorb light and by using water as an electron donor in a similar way to plants. These organisms contain specialized plasma membranes which contain these photosynthetic pigments. Nonetheless, it is important to highlight that algae are the most important photosynthetic organisms in aquatic environments, while plants are the most important photosynthesizers in terrestrial environments.

One of the benefits of bite mark analysis is that clear bruising from a perimortem bite persists for weeks after the victim has died.
a. True
b. False
Answer:
False. Bite marks persist for hours, not weeks.
Explanation:
In a dead body, the marks left by a bite do not persist for a long time. In general,
if the bite was produced when the victim was still alive, the marks are recognizable for a period of 4 to 36 hoursif the bite was done after the individual´s death, then these marks might persist for a period between 12 and 24 hours after the victim was bitten.Also, it is important to consider that dehydration and putrefaction originate retraction of tissues and modify the original aspect of the bite.
The statement that bite mark analysis from clear bruising as a result of perimortem bite will persists for weeks when victim must has died is a benefit is false.
This statement is false because from bite mark analysis, bite usually last fir hours depending of the kind of bite and not weeks.Bite mark analysis serves as imperative area of forensic odontology which is a form of dental evidence that could be presented in criminal court.Therefore, the statement is false.

Use material in your classroom, online, or in books to find images and descriptions of two nonprimate mammals (such as dogs, horses, dolphins, or raccoons). What traits do these animals share with primates? What important primate traits do they lack?
Answer:
Explanation:
Non-primate mammals (such as dogs, dolphins and raccoons) have some similar traits with primates (such as monkeys, humans and baboons). Some traits that these non-primate mammals share with primates include
1) They are warm-blooded just as the primates
2) They give birth to there young ones alive
3) There body system also permits complex forms of metabolism
And some of the traits that non-primate mammals lack that primate mammals have ar
1) They lack the ability to hold on to "materials" because of the morphology of there palm/hand/foot.
2) They do not have forward facing eyes which provides for enhanced vision in primates
3) Most primates can stand upright (via bipedalism) as against other nonprimate mammals
If warmer oceans soak up less CO2, what effect do you think rising ocean temperatures will have on the amount of CO2 in the atmosphere ?
Answer:
Warmer water cannot hold as much carbon dioxide, so the ocean’s carbon capacity is decreasing as it warms. In watching for effects of increasing atmospheric carbon on the ocean’s uptake, many people have looked for indications that the carbon content of the ocean is rising faster than that of the atmosphere.
Explanation:
If warmer oceans soak up less CO2, rising ocean temperatures will lead to more CO2 in the atmosphere.
CO2 is being released into the atmosphere both from natural and anthropogenic sources. The natural sources include volcanic eruption, cellular respiration, etc. while anthropogenic sources include all human actions that lead to CO2 emission such as the burning of fossil fuels, agricultural burnings, deforestation, etc.
As net amounts of CO2 is being released into the atmosphere and warmer oceans soak up less CO2, the atmospheric concentration of CO2 will keep increasing.

Explanation:
A student claimed that the following two proteins are the same protein because they contain the same amino acids: (1) Pro-Arg-Lys-Iso-Gly and (2) Pro-Arg-Lys-Gly-Iso. Do you agree or disagree with the student?
Answer:
Disagree
Explanation:
Proteins are made up of chains of amino acids, these fold up and join up with other polypeptides to form the final structure of the protein.
The amino acids are in a different order (Iso and Gly are swapped around). This means the polypeptide chain is different, meaning the final structure and likely the function of the protein will be different.
Therefore, the proteins are certainly not the same protein.

How does the growth and development of Caulerpa compare to that of a typical multicellular plant?
Answer:
Caulerpa is a unicellular organisms
Explanation:
Caulerpa is a unicellular organisms and has its organelles within it's cell wall. It's an algae that have chloroplast which is use to produce food. They grow and develop to that length that is more than half a meter and they possess structure which look like real stems,roots of multicellular plants. They reproduce when adult produce sperm and egg and fuse together to produce another offspring. A single cell wall surrond the the root tips to the leaves and they move freely within the fluid.
Why is nitrogen important for the plants?
Nitrogen is so important to plants because it is a major component of chlorophyll , or the compound by which plants use sunlight energy to produce sugars from water and carbon dioxide (photosynthesis). It is also a major component of amino acids, the building blocks of proteins for plants.
How many CO2 molecules are produced when three glucose molecules undergo cellular respiration? Explan
Answer:
18 molecules of [tex]CO_{2}[/tex]
Explanation:
In heterotrophic nutrition, organisms ingest or absorb food made by autotrophs to obtain energy. Planta and other photosynthesizing organisms make sugars via photosynthesis, in a form of (partly) light-dependent biosynthesis.
In mitochondria, they break down sugars through aerobic respiration. For the sugar glucose, this results in the production of carbon dioxide and water along with energy in the form of ATP or adenosine triphosphate.
C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP
glucose+ oxygen → carbon dioxide+ water+ energy
For 3 molecules of glucose, multiply the number of reactants and products...
(C6H12O6+ 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP ) x 3
Thus...
3 C6H12O6+ 18 O2 → 18 CO2 + 18 H2O + ≅114 ATP
