Answer:

The population of phytoplankton will decrease, hence, resulting in a drop in oxygen production.

Explanation:

This question shows the activities that take place in an ocean habitat. The question is a typical example of a food chain where organisms feed on one another in order to obtain energy.

According to the question, the feeding relationship among the organisms is as follows:

Phytoplankton → Shrimp → Salmon → Humans

Phytoplankton, in this question, is said to produce half of the oxygen used on Earth. Hence, if the population of shrimps increased, it means that the population of phytoplanktons would decrease because there would be more shrimps to feed on them. This decline in the plankton population will cause a reduction in the world oxygen production.

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:

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:

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.

When a paper cut breaks the skin, it introduces outside microorganisms into the cut. The body recognizes the break in the skin. Mast cells produce histamines, which cause more blood and lymph fluid to flow to the wound. This increased flow brings phagocytic white blood cells to the area, which destroy invading organisms until the blood can clot and the skin can heal over the cut, preventing more organisms from entering the body. If a cut is too deep or too wide, special care such as stitches and antibiotics could be needed to prevent infection.

Answer:

Sperm cells are not normally exposed to blood, but if they are, the immune system may produce __auto-antibodies__ against sperm cells' __auto-antigens_ and render someone sterile.

Explanation:

Auto-antibodies are antibodies that can destroy cells from the same organism. They are mistakenly directed against organs or tissues of the same organisms, causing auto-immune diseases or affections. The autoantibodies action occurs when the organism fails in recognizing its own cells and faces them as strange elements.

Auto-antigen is the molecule produces by the body that fails in being recognized due to a break up in the tolerance mechanisms, triggering an immune response.

In the exposed example, sperm cells do not usually mix with blood. So when they do, blood cells recognize them as strange bodies and act against them. Sterility might be an effect of this auto-immune response.

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.

The liver is simply the largest solid organ in the body and it can be found below the rib cage in the upper abdomen by the right. It's function is to maintain the blood sugar, regulate blood clotting and remove toxins from the blood.

It should be noted that the liver develops as a ventral outgrowth of the embryonic foregut. It also helps in the incorporation of both the endodermal and the mesodermal components. Furthermore, it's developed in the ventral mesentery and is connected to the stomach by the lesser omentum.

Therefore, all of the above options are correct.

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: Touch.

Explanation:

Cilia are short, mobile prolongations which contain a central structure made up of microtubules and proteins, enveloped by the cytosol and the plasma membrane. They are involved in cell movement, transport of materials, displacement of fluids, among others. Cilia are important for many biological processes, such as the senses of taste, hearing, smell, sight and balance.

For example, each taste bud of the tongue is made up of a set of cells, among which are the taste cells that have cilia that come into contact with the substances dissolved in the mouth by saliva. As for the sense of hearing, when there is a sound, the endolymph in the cochlea moves and this stimulates the cilia of the internal sensitive cells, which communicate with the acoustic nerve that informs the brain of what the sound is like. In the sense of smell, the receptors are the olfactory cilia of the olfactory neurons, which are located in the mucosa of the upper portion of the nostril, above the level of the superior concha. In the sense of vision, cones and rods are the two types of photoreceptor cells that capture light energy and convert it into electrical signals. They are highly specialized cells and can be differentiated into several regions: an outer segment, an inner segment containing the nucleus and a synaptic terminal. The outer segments are modified cilia and consist of flattened membranous sacs or disks.  As for the balance system, the vestibular system consists of the utricle and the saccule, which are chamber-shaped organs filled with endolymph. The maculae of the saccule are located in a vertical plane and effectively capture the accelerations of the upward and downward movements of the head, and therefore of the gravitational forces. The hair cells of the maculae are responsible for transforming the mechanical energy produced by movement into nerve signals. The activity of these cells is determined by their morphofunctional polarization or ciliary organization, which is different in the utricle and in the saccule.

Thus, the only sense that does not depend on cilia to transmit stimuli is touch. The skin contains nerve endings, as well as glands, blood vessels and hair follicles. These nerve endings detect pain, touch, pressure and temperature.

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.
