Answer:

The correct answer is ''deuterostome''.

Explanation:

Deuterostomes are a superphylum of animals in which the anus is formed in or near the blastopore area in the developing embryo, and the mouth is secondarily formed elsewhere. The oral apparatus that these adult animals enjoy does not come from the embryo's blastopore. Instead it is a new formation. They enter the Bilateria classification, where species that enjoy bilateral symmetry are incorporated. In deuterostomes, the primary phases of division occur in parallel to the axis between the tips. That is, the segmentation they have is radial when the embryo is in state 1 with four cells.

Explanation:

Nucleosides have nitrogen base surrounded by 5 carbon carbohydrates which is called as ribose molecule. Nucleotides is simply a nucleoside with one or more phosphate group. There are 4 different types of nucleosides which are, adenosine,  guanosine cytidine, and uridine. Nucleotides are formed from nucleosides by esterification of inorganic phosphate on aldose.

The phenotypic ratio of the cross is as follows: 3 red antennas: 1 white antenna

For question 2, the phenotypic ratio of the F2 generation is: 3 black-eyed: 1 orange-eyed

QUESTION 1

According to the first question, a gene coding for antenna color in butterflies is involved. Red antennas (“R”) is dominant to white antennas (“r”). Hence, a butterfly with genotype "Rr" will be phenotypically red.

According to this question, If both parents are heterozygous for red antennas i.e. Rr (red antenna) × Rr (red antenna), the following gametes will be produced: R and r. Using these gametes in a punnet square (see attached image), the following phenotypic ratio of offspring is produced:

3 RED ANTENNAS (RR, Rr, Rr) : 1 WHITE ANTENNA (rr)

2. In the second question, all the offspring of a cross between a black-eyed mendelien (BB) and an orange-eyed mendelien (bb) have black eyes (Bb). In a cross between two F1 black-eyed mendeliens i.e. Bb × Bb, the following proportion of offspring is produced:

BB, Bb, Bb, bb

Hence, a phenotypic ratio of 3 black-eyed: 1 orange-eyed

Answer:

High levels of leptin are interpreted as overfeeding.

Insulin stimulates production of leptin in adipocytes.  

Higher leptin levels result in a decrease in appetite.

Explanation:

Leptin is a peptide hormone that helps to control body weight. This hormone (leptin) is synthesized by fat cells (i.e., adipocytes), then circulates in the blood and goes to the brain, in particular in a region of the brain called the hypothalamus, where it acts to alter food intake over the long term. Higher leptin levels trigger the hypothalamus to lower the appetite. Insulin is another peptide hormone that acts to regulate long-term leptin secretion of adipose cells through a posttranscriptional mechanism. In turn, leptin increases insulin sensitivity, thereby both hormones regulate each other. When body fat decreases as a consequence of decreased appetite, insulin and leptin concentrations in the bloodstream also decrease.

Answer:

Based on their roles, the neurons found in the human nervous system can be divided into three classes: sensory neurons, motor neurons, and interneurons.

Explanation:

Neurons are classified functionally according to their direction. The nerve impulse travels relative to the receiving neuron.

Neurons may be defined as nerve cells that are responsible for the transmission of signals from the body to the brain.

Afferent neurons are the neurons of the sensory nervous system. They are responsible for conducting nerve impulse input from both somatic sensory and visceral sensory receptors. Most sensory neurons are afferent neurons.

Efferent neurons are the neurons of the motor nervous system, conducting nerve impulse output from the central nervous system to the effectors. All motor neurons are efferent neurons.

Interneurons or associated neurons lie entirely within the central nervous system. They receive stimulation from many other neurons and carry out the integrative function of the nervous system. The most numerous types of neurons are interneurons.

Therefore, it is well described above.

Answer:

During the conversion of glucose to pyruvate glycolysis or during the conversion of pyruvate to alcohol

Explanation:

During the conversion of glucose to pyruvate, NAD+ is converted into NADH.

Alcoholic fermentation is a biological process that converts sugars into cellular energy while emitting ethanol and carbon dioxide as byproducts.

The NADH + H+ from glycolysis would be recycled back to NAD+ during the fermentation process, allowing glycolysis to continue. NAD+ is reduced during glycolysis to form NADH + H+.

Thus, during this, when glucose is converted to pyruvate, NAD+ is being converted to NADH.

Answer:

The correct answer is -

Numerator = 6

Denominator = 73

Explanation:

In F static test or table there are two sets of degrees of freedom: one for the numerator and one for the denominator. The degrees of freedom are equal to the number of observations minus one. Thus, if the sample size were 7 then the degree of freedom would be 7 minus 1

Numerator df = 7 - 1 = 6

Thus, the numerato would be - 6.

Denominator is calculated by subtracting the observation or variables from the total number of sample size.

Denominator df = 80- 7 = 73

Answer:

Macula densa cells, lower and renin.

Explanation:

Macula densa cells in the kidney detect lowers blood pressure which causes renin to be released from the juxtaglomerular cells which is  an enzyme. The arterial cells observe the drop in blood pressure, and the decrease in Na concentration is transfer to them by the macula densa cells. The juxtaglomerular cells then release an enzyme called renin. Renin converts angiotensinogen which is a peptide, or amino acid derivative into angiotensin-1.

Answer:

The correct answer is - B. Ocean deoxygenation.

Explanation:

Eutrophication is the process in which a water body gets excessively rich in nutrients that leads to the algal growth or plankton growth in this region and covers the complete surface or most of the water body.

Due to this algal and plankton growth, there is a significant decrease in the concentration of the dissolved oxygen in water bodies that result in the incapability of supporting the lives found in it. The primary and main reason for this deoxygenation is eutrophication. Ocean deoxygenation is the reduction of the oxygen concentration of the oceans.

Answer:

Some bacterias show a great resistance power to fight against T4 phages That leads to great growth in the medium given that resistance power may be given by plasmids As plasmids show the resistant genes that great work in the medium.

T4 phage is a virus that shows a lytic cycle after affecting bacteria and going to kill the bacterial cells in bacterial strain So no growth in LB media. Some bacteria are sensitive due to the lack of resistant genes therefore, their growth may affect by many factors of the medium. If the bacteria are recombinant, they show greater growth in the medium.

* B-Amp, Phage plate (strain Be), there is ampicillin, so inhibits the growth of bacteria but still there is patchy growth of bacteria and they still show the growth but due to presence of phage T4, they show patchy growth.

Answer: [Vmax]= 6mM/min.

Explanation:

Enzymes are proteins that produce a specific chemical change in a substance, called substrate, resulting in a product. By following the rate of product appearance (or disappearance of the substrate) as a function of time, the kinetics of the reaction is obtained. As the reaction proceeds, the rate of product formation decreases and the substrate is consumed.

The rate [V] indicates the amount of substrate that is converted into product per second. With increasing substrate concentrations [S], the enzyme approaches its maximum velocity [Vmax], but does not reach it. For this reason, there is no specific value of [S] for Vmax. However, a characteristic parameter of the enzyme can be defined using the substrate concentration at which half of the maximum velocity (Vmax/2) is reached. The initial velocity of the reaction is equal to the slope of the zero-time forward curve and is measured before 10% of the total substrate is consumed, so that the substrate concentration can be considered as essentially constant throughout the experiment. So, although it is impossible to measure exactly the substrate concentration that gives Vmax, enzymes can be characterized by the substrate concentration at which the reaction rate is half the maximum rate. This substrate concentration is known as the Michaelis-Menten constant (KM). For enzymes exhibiting simple Michaelis-Menten kinetics this constant represents the dissociation constant of the enzyme-substrate complex (or the inverse of the enzyme-substrate affinity). Thus, Km indicates the affinity of the enzyme for its substrate, since the higher the Km the lower the affinity. And the lower the Km the higher the affinity.

The formula for the calculation is as follows:

[tex]V_{0}= \frac{[Vmax] x [S]}{[S]+[KM]}[/tex]

So if we replace the numbers, we get:

[tex]2mM/min= \frac{[Vmax] x [4mM]}{[4mM]+[8mM]}[/tex]

If we clear the equation, we obtain that [Vmax]= 6mM/min.
