Which capillary would be least likely to allow substances to enter or exit the blood due to tight junctions that join the endothelial cells
Answer:
Those capillaries that have endothelial cells tightly attached have an increase in cell-to-cell junctions, such as desmosomal junctions that are poorly permeable to substances.
These capillaries generally function as conductors or collectors and not as permeabilizers like the pulmonary capillaries that are fenestrated and allow a high passage of substances and gases.
The capillaries are waterproof and prevent the passage of substances or fluids such as in the blood-brain barrier that is very selective
Explanation:
The blood-brain barrier is too selective since it is not favorable for the organism that many fluids, drugs, substances or chemical compounds enter the brain space.
This is the reason why the vessels are waterproof and why pharmacology was challenged to invent drugs that could cross this barrier since it was considered impossible.
An example is dopamine, which in parkynson's disease the levo group is added to dopamine, thus forming levodopamine as a product, this is the only way that the drug crosses the blood-brain barrier and can pass the impermeable barrier generated by capillaries with endothelial cells that are close to each other or closely linked
What best describes the behavior of nonconservative elements in seawater?
The given question is incomplete due to missing options, however, the options for the question as follows:
A. Nonconservative elements are reactive in seawater and have a long residence time.
B. Nonconservative elements are reactive in seawater and have a short residence time.
C. Nonconservative elements are non-reactive in seawater and have a short residence time.
D. Nonconservative elements are non-reactive in seawater and have a long residence time.
Answer:
The correct answer is option C.
Explanation:
Non conservative components are components that enter the ocean water and have little concentration in the sea and show spatial variations. These components have short home time that is short replacements time and they are non responsive.
Constituents, for example, phosphate, nitrate, and different supplements, and broke up oxygen, carbon dioxide, and so on are non-conservative on the grounds that their concentrations are later altered by chemical reactions in the ocean.
Thus, The correct answer is option C.

a. 185 calories
b. 178 calories
c. 180 calories
d. 190 calories
e. 188 calories
Answer:

The answer is "Gene"
Explanation:
What are the values of a, b, and c in the quadratic equation 0 = 5x – 4x2 – 2? a = 5, b = 4, c = 2 a = 5, b = –4, c = –2 a = –4, b = 5, c = –2 a = 4, b = –5, c = –2
Hey there! :)
Answer:
The 3rd choice. a = -4, b = 5, c = -2.
Explanation:
Rearrange the quadratic equation given into the form 0 = ax² + bx + c:
0 = 5x - 4x² - 2 --> 0 = -4x² + 5x - 2
The corresponding coefficients for the a, b and c values are:
a = -4
b = 5
c = -2.
The given quadratic equation must be first rearranged in the form ax2- bx-c. From this, we can find the values of a= -4, b= 5, and c= -2
How can a quadratic equation be defined?Quadratics can be defined as a polynomial equation of a second degree, which implies that it comprises a minimum of one term that is squared. It is also called quadratic equations. The general form of the quadratic equation is ax² + bx + c = 0.
Quadratic equations are commonly used in situations where two things are multiplied together and they both depend on the same variable. For example, while working with the area, if both dimensions are represented in terms of the same variable, you use a quadratic equation.
Throwing a ball, shooting a cannon, diving from a platform, and hitting a golf ball are all examples of situations that can be modeled by quadratic functions.

Label the figure ,illustrating the functional classification of neurons.the orange arrows show the direction of impulse conduction
Answer:Image in attachment.
From the left side to the right in sequence
1. sensory receptors→peripheral nervous system→(bipolar neurons;sensory/motor neuron) → CNS-interneurone→motor neuron →effectors.
Explanation:
The sequence of actions represents the reflex pathways for the transmissions of action potential in living organisms. It is therefore called a reflex arc.
Its represent the transmission of sensory impulses from the peripheral nervous systems through the sensory neurons, to the CNS(brain and spinal cord) as it enters at the dorsal roots and the transmission of responses to the defectors, gland and muscles, for effective responses.
The brain and spinal cords process these information,the brain mediates the information,while the spinal cord serves as the neuronal conduits for the transmission of the impulses through its ventral roots to the effectors via the motor neuron.
Construct at least two possible hypotheses for the student’s experiment
Answer:
OFFICIAL SAMPLE ANSWER (Do not copy verbatim):
Hypothesis 1: The natural nutrients in compost will cause the tomato plants to grow at a faster rate than they grow when given artificial fertilizer.
Hypothesis 2: The artificial fertilizer is formulated specifically for tomato plants, so it will cause the plants to grow at a faster rate than they grow when given compost.
Explanation:
If questioned for situation below.....
"Many farmers and gardeners compost their plant and animal waste. The living material naturally decays in compost bins, forming a dirt-like substance that’s rich in nutrients. The next season, farmers use this substance as a natural fertilizer for their crops.
A biology student has grown tomato plants for several years. Until now, he used an artificial fertilizer formulated for tomato plants. This fertilizer caused his plants to grow faster and taller than they grew in unfertilized soil. The student wants to know whether using natural compost will cause his tomato plants to grow faster and taller than his artificial fertilizer.
"
1. compost pits and manure use, bio gas can be produced
2. using natural compost replenishes the soil fertility in the long run unlike the chemical fertilizers are two possible hypotheses for the student’s experiment
What are the basics of experiment ?The basics of experiment is to test the hypothesis what we set previously and it is a foundation of the scientific method, types of experiments include controlled experiments, field experiments, and natural experiments.
The key steps taken in scientific method are observations, ask a question, making of hypothesis, design and conduct experiment, result, accept or reject or repeat the hypothesis from result.
The most important parameter taken in an experimental set up is variable which can be dependent, independent and controlled variables where the independent variable is something which can not influenced by other factor.
A dependent variable can be changed by the influence of independent variable and Control variable can be used to check bias of experiment.

PLEASE HELP. DONT ANSWER IF YOU DONT KNOW. Name any three specifications that reduce carbon dioxide expenditure and promote biodiversity.
Answer:
A carbon footprint is the total greenhouse gas (GHG) emissions caused by an individual, event, organization, service, or product, expressed as carbon dioxide equivalent.[1] Greenhouse gases, including the carbon-containing gases carbon dioxide and methane, can be emitted through the burning of fossil fuels, land clearance and the production and consumption of food, manufactured goods, materials, wood, roads, buildings, transportation and other services.[2]
In most cases, the total carbon footprint cannot be calculated exactly because of inadequate knowledge of and data about the complex interactions between contributing processes, including the influence of natural processes that store or release carbon dioxide. For this reason, Wright, Kemp, and Williams proposed the following definition of a carbon footprint:
Specifications that reduce carbon dioxide expenditure and promote biodiversity are as follows:
1. Provide tree plantation through urban afforestation.
2. It has low concentration of carbon dioxide as plants absorb this gas and release oxygen
3. By promoting fruits and shade for the neighborhood.
What is Carbon Dioxide?Carbon dioxide is defined as the chemical compound which is made up of molecules each containing a carbon atom bonded twice to two oxygen atoms and is found in the gaseous state at room temperature. In air, carbon dioxide is transparent to visible light but absorbs infrared radiation which acts as a greenhouse gas.
This is a minor component of the Earth's atmosphere at about 3 volumes in 10,000 employed by plants in the combustion of carbon-containing material, in fermentation, and in the respiration of animals and in the photosynthesis of carbohydrates.
Thus, specifications that reduce carbon dioxide expenditure and promote biodiversity are as follows:
1. Provide tree plantation through urban afforestation.
2. It has low concentration of carbon dioxide as plants absorb this gas and release oxygen
3. By promoting fruits and shade for the neighborhood.

difference between plant and animal cyanide resistance respiration.
Answer:
The cyanide resistant respiration differs in plants as oxidation of reduced coenzyme continues even in the presence of cyanides.
Explanation:
The mitochondrial is the electrons through which the animals and plants perform the aerobic exercise and is blocked by the release of the cyanides that stops the activity and is known as cyanide sensitive respiration Plant mitochondria is different from the animal as they both have different oxidase system pathways. Cyanide resistant is responsible for the climacteric in fruits and for the generate heat in thermogenic tissues. What is the most likely explanation for how speciation occurs?
