(a) If a particular gene is located on the Z chromosome of this lizard species, describe why a lizard with a ZW genotype has a g
Airida [17]

Answer:

If there is no dominant allele for a trait present on a homologous chromosome to mask the recessive allele, the recessive phenotype will be expressed. In this case, the gene is located on the Z chromosome. In an individual with a ZW genotype (female) there is no homologous Z partner, meaning whatever allele is present on the solitary Z chromosome will be expressed.

What is lipid droplets? Why can it be used as a new biofuel?
dimulka [17.4K]

Answer:

Nowadays energy generation heavily relies on fossil fuels causing environmental challenges. The global biofuels supply has increased by a factor of 8% since 2010, but only comprises 4% of the world’s transport fuels in 2015. The development of next generation of biofuel becomes increasingly important due to the depletion of fossil fuels and in the meantime to overcome challenges for current biofuels production – high cost and low efficiency. The biological production of lipid droplets in oleaginous microorganisms like microalgae, yeast, fungi, and bacteria becomes a promising path to the next generation of biofuels.

The lipid droplet (LD) is a cellular organelle that consists of a neutral lipid, mainly of triacylglycerols (TAGs) and cholesteryl esters, cored with a monolayer-phospholipid membrane and associated proteins. Lipid droplets widely exist in both prokaryotic and eukaryotic cells, could be collected and extracted for biofuel manufacturing. However, this technology is now limited in lab research. Methods to improve the lipid droplet production in oleaginous microorganisms, biomass pretreatment, lipid droplet extraction, industrial scalability are still under development. The experience of liposome manufacturing provides us a solid ground for lipid droplet studies and helps our clients move to a further step of new biofuel development.

Tall plants are dominant over short plants. One parent is homozygous dominant and the other is heterozygous for plant height.
Greeley [361]

Answer:

a. all tall

Explanation:

If genotypically one of the parents is homozygous dominant and another one is heterozygous for plant height then phenotypically all their progeny will be tall.

Let us suppose, 'T' represents dominant allele and 't' represents recessive allele. Then the genotype of one parent who is homozygous dominant will be TT and genotype of another parent  who is heterozygous will be Tt.

The cross is depicted in the attachment.

Here it may also be noted that genotypically two of the progeny will be homozygous dominant while two of the progeny will be heterozygous but phenotypically all the progeny will be 'tall'.

I’m which part of the cell is the majority of the energy released from breakdown of glucose
poizon [28]

Sentence Correction: In which part of the cell is the majority of the energy released from the breakdown of glucose?

nucleus

mitochondrion

cytoplasm

plasma membrane

Answer: <em>The answer is mitochondrion.</em>

Explanation: <em>The reason the is the correct answer is because, there are the Locations of Cellular Respiration which occurs in two stages.</em>

<em>First stange - cytoplasm</em>

<em>Second stage - mitochondrion</em>

<em>So as we can see, mitochondrion is the Second stage which is the correct answer because the majority of the energy released from the breakdown of glucose.</em>
