How many genetically different kinds of sperm could be produced by a Drosophila melanogaster male (XY)
Answer:
The correct answer is - 16 genetically different kinds of sperm could be produced by a Drosophila melanogaster male (XY).
Explanation:
There are four pairs of chromosome in Drosophila melanogaster. In this species homologous chromosomes pair and segregate but do not follow recombination or crossing over. Each chromosome has two alleles or copies so as we know there are four pairs of chromosomes, then total number of chromosome copies would be 8, then
number of different combinations = 2^n (n = number of homologous pairs
)
2^n
= 2^4
= 16
Thus, the correct answer would be : 16.

what is the difference between Eukaryotes and prokaryotes
Answer:
Prokaryotes are unicellular organisms that lack membrane-bound structures, the most noteworthy of which is the nucleus. Prokaryotic cells tend to be small, simple cells, measuring around 0.1-5 μm in diameter.While prokaryotic cells do not have membrane-bound structures, they do have distinct cellular regions. In prokaryotic cells, DNA bundles together in a region called the nucleoid.Eukaryotes are organisms whose cells have a nucleus and other organelles enclosed by a plasma membrane. Organelles are internal structures responsible for a variety of functions, such as energy production and protein synthesis.Eukaryotic cells are large (around 10-100 μm) and complex.

Glucose enters erythrocytes via a GLUT-1 uniporter. As the levels of glucose in the bloodstream decrease between meals, what happens to the glucose in the cells? A. Glucose leaves the cell through the GLUT-1 uniporter, traveling down the new concentration gradient. B. Glucose remains in the cell because uniporters can only transport in one direction. C. Glucose remains in the cell because the GLUT-1 uniporters are gated and the gates close at low glucose concentrations. D. Glucose remains in the cell because it has been phosphorylated and no longer has affinity forthe GLUT-1 uniporter.
Answer:
A. Glucose leaves the cell through the GLUT-1 uniporter, traveling down the new concentration gradient.
Explanation:
The Glucose transporter 1 (GLUT1) protein is a critical uniporter transporter that facilitates the movement of glucose molecules across the plasma membrane. The expression of GLUT1 is increased when glucose concentration is reduced and, inversely, GLUT1 expression is reduced when glucose levels are increased. The erythrocytes are cells that continuously require the supply of glucose from the blood plasma, this mechanism involves the function of GLUT1 that permits the energy-free passage of glucose by diffusion.

Answer:
A. gain-of-function intracellular signal molecule (LET-60) activated by lin-3 mutants
E. gain-of-function lin-3 receptor mutants
Explanation:
Genetic suppressors are widely used in molecular genetics to study gene function in specific developmental stages and target tissues. Suppressing mutations are second mutations triggered at a different site from the mutation of interest in order to suppress the phenotypic effects caused by the first mutation. Caenorhabditis elegans is a model organism to produce genetic suppressors by taking advantage of its rapid generation time and large populations, which enables the application of rapid and powerful mutation screening procedures in the same experiment. In addition, this species reproduces by self-fertilization, thereby both dominant and recessive suppressors can be easily obtained.
how are red blood cells able to move through narrow vessels to carry oxygen throughout a multicellular organism?
Answer:
The correct answer is - they lack a nucleus.
Explanation:
Red blood cells or erythrocytes are anucleated, biconcave, and small specialized cell that produce in bone marrow and lacks the mitochondria at maturity. RBC plays very important role to carry oxygen from lungs to deliver it to the various parts of the body and carry out carbon dioxide from various part to back to the lungs.
Due to lack of the cell organelles and nucleus, these cells are smaller in size. The size of RBC circulate throughout the body through narrow vessels due to its specific size and shape that provide it space for hemoglobin that binds with oxygen.
Thus, the correct answer is - they lack a nucleus.

Earth's Greatest Enemies?Climatologist James Lovelock(originator of theGaia_hypothesis ) once said that Earth's greatest enemies were cars, cows and chainsaws because of their contributions to destabilizing planetary climate.1. How do each of these things (cars, cows, andchainsaws) contribute to the destabilizing of Earth's atmosphere and climate? You must cite specificevidence from any Unit of the course to support your response. And...2. How are these three things connected to one another either by cause, effect or by solution. Consider all of the environmental concerns you have been learning about during the entire course and describe how these 3Cs as a group relate to one specific environmental issue (other than atmospheric destabilization).Reminder: Loss of land plants will not result in a reduction of atmospheric oxygen (because most of planetary photosynthesis and its resulting oxygen production is in the oceans).
Cars, cows and chainsaws are major polluters and their use must be regulated and limited, to reduce the emission of polluting gases into the atmosphere that can cause drastic climatic changes that harm the environment that we know intensely.
Although it is not widely publicized in the media and few people know about it, the chainsaw is a great villain of the earth's atmosphere, since its use releases large amounts of CO2 into the atmosphere, due to the burning of gasoline that these machines make to work. CO2, in addition to endangering the operator's life, is a gas that destroys the ozone layer and increases the effect of global warming. Not only does the chainsaw release this gas, but so do cars, which reinforces the need to use renewable fuels to be used in both cases.
Cows also release polluting gas, methane, which has a greater polluting potential than CO2. Methane is the result of the cow's digestive reactions, which release this gas into the atmosphere steadily. As herds of cows tend to be large, livestock becomes a major polluter, as herds result in a strong release of methane into the environment. This reinforces the need for increasingly stronger regulations for livestock, in addition to highlighting the importance of adopting alternative methods of feeding that reduce meat intake.

identify substrate:
Describe the relationship between the substrate and enzyme in the scenario:
Answer:
Identify enzyme: Enzymes are named by adding the suffix -ase to the name of the substrate that they modify or the type of reaction they catalyze(dehydrogenase, decarboxylase)
Identify substrate: the substrate is a molecule upon which an enzyme acts.Enzymes catalyze chemical reactions involving the substrate(s). In the case of a single substrate, the substrate bonds with the enzyme active site, and an enzyme-substrate complex is formed.
Describe: Enzymes bind with chemical reactants called substrates. There may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. In some reactions, a single-reactant substrate is broken down into multiple products. ... The enzyme's active site binds to the substrate.
I hope this helps :)
The enzyme in this case is lactase and the substrate is lactose.
What is the enzyme-substrate relationship?In biochemistry, the molecule on which an enzyme operates is known as the substrate. Enzymes catalyze chemical reactions involving the substrate(s). The substrate is changed by the active site into one or more released products. The active site is then ready to accept a fresh substrate molecule.
To catalyze a reaction, an enzyme will grab (bind) to one or more molecules of the reactant. These substances serve as the enzyme's substrates. In certain reactions, a single substrate can be broken down into a variety of products. Others involve the joining of two substrates to create a larger molecule or the switching of parts. In fact, every biological reaction may probably be sped up by an enzyme.
The fundamental idea should be relatively evident despite slight differences in the definitions of the substrate in general chemistry and biology. A substrate is commonly understood in chemistry as a chemical substance that may be changed by the action of another substance. Without the aid of an external catalyst or enzyme, the transformation takes place in the substrate itself, and in most cases, given enough time, it may happen on its own.
Therefore, lactase is the enzyme and lactose is the substrate.

Answer:
The correct answer is :
Independent Variable: side of the shower with lemon juice
Dependent Variable: cleanliness of shower
Control: spray of water
Conclusion: lemonade juice have no effect on slime
Explanation:
Independent variable in any experiment is the variable that is changed or manipulated as here side of the shower that is sprayed with lemonade juice is manipulated to see if there is any effect on the cleanliness of shower.
Dependent variable is the variable that is observed or measured to check if manipulated variable or independent variable have any effect on it, like the cleanliness is measured to check if lemonade juice clean the slime of the side or not.
The control is something that remains the same to check the condition or effect that is not changed or can be compared to it. Water spray is control in this case.
The conclusion of this experiment is that there is no effect of lemonade juice on the cleanliness of slime present in the shower
In any experiment, an independent variable is the variable that is altered or manipulated, such as the side of the shower that is sprayed with lemonade juice to determine if it has any influence just on cleanliness of the shower.
This dependent variable is a variable that can measure Lemonade a manipulated variable or independent variable has any effect on it, such as whether lemonade juice cleans the slime off of the side or not.
A control is something that remains unchanged to assess the condition or impact which has not changed or may be contrasted to it. In the this scenario, the water spray is under command.
The experiment concludes drinking lemonade seems to not influence the cleaning of slime inside the shower.
Each side of the shower with lemon juice is an independent variable.Shower cleanliness is a variable.A water spray can be used to keep things under control.In conclusion, lemonade juice does not affect slime.Learn more:

Describe how a lysosome enzyme would normally be created, including the steps involved and the organelles that contribute to the process
Answer:
Lysosomal enzymes are produced in the ER and transported to the Golgi complex to be finally incorporated into acidified vesicles
Explanation:
Lysosomes organelles are generated by the fusion of vesicles from the Golgi complex with endosomes. This organelle contains more than 50 types of hydrolytic enzymes capable of breaking down different macromolecules. Lysosomal enzymes are produced in the endoplasmic reticulum (ER), and then they are exported to the Golgi complex, where mannose-6-phosphate (M6P) label is added to be finally packaged into acidified vesicles. Mutations in the genes that encode for lysosomal enzymes are known to produce Lysosomal Storage Diseases (LSD) including Tay-Sachs disease.

PLEASE HELP ME!!!! This figure shows two alleles for the beta-globin gene. The A allele is the most common allele. The S allele is responsible for Sickle Cell Disease. The R group glutamic acid is negatively charged, while the R group of valine is hydrophobic. What molecular change, ultimately resulting in the sickle cell phenotype, occurs when valine in substituted in place of glutamic acid at position 6 in the β subunit of hemoglobin?
Answer:
The correct answer is option B. The tertiary structure of the beta subunit changes, exposing a hydrophobic cleft which allows hemoglobin to form long chains in RBC.
Explanation:
As it is clearly mention as there is point mutation that leads to single nucleotide change which results in to valine instead of glutamate. Valine is hydrophobic in nature not like glutamate. Valine aggregate and makes a rigid structure of molecules.
Due to this rigid molecule of valine aggregates, RBCs form a crescent or sickle like shape due to the higher viscosity and low solubility of Mutated hemoglobin in deoxy condition. It leads to formation of polymer that blocks the vessels.
Thus, the correct answer is option B.
