The fetus receives all its nutrients and oxygen through the placenta. Therefore, fetal lungs are non-functional, as far as pulmonary circulation is concerned. It only needs to receive enough blood to sustain growth. There are a couple of features in the fetal cardiovascular system to shunt the blood away from the lungs and only provide enough for sustenance and keep most blood in general circulation. Which two structures in fetal circulation aid in bypassing the pulmonary circulation
The two structures in fetal circulation that aid in bypassing the pulmonary circulation are:
ductus arteriosus andductus venosusThe fetal circulation, the fetal heart doesn't pump much blood to the liver and the lungs. This is because it receives nutrients from the mother through the placenta.
Two of the structures that shunts blood away from the heart are:
ductus venosus: When blood enters the placenta through the umblical vein, it passes through the ductus venosus, mainly bypassing the liver.ductus arteriosus : The deoxygenated blood from the head region of the fetus is pumped through the right ventricle into the pulmonary artery and then mainly through the ductus arteriosus into the descending aorta, then through the two umbliical arteries back into the placenta.The above described features bypasses blood away from the lungs through ductus venosus and ductus arteriosus.

Can a hypothesis be proven true? Why or why not?
Answer: Hello! xoxo
Upon analysis of the results, a hypothesis can be rejected or modified, but it can never be proven to be correct 100 percent of the time. For example, relativity has been tested many times, so it is generally accepted as true, but there could be an instance, which has not been encountered, where it is not true.

BiomeCommunityEcosystemHabitati Need help with science Which two groups of elements in the periodic table are the most reactive?
A halogens and noble gase
B alkaline earth metals and halogens
C alkali metals and halogens
D noble gases and alkali metals
Answer: alkali metals and halogens
Explanation:
The two groups of elements in the periodic table those are the most reactive are alkali metals and halogens. The correct option is C.
What is periodic table?The periodic table (also known as the periodic table of elements) is organized so that scientists can quickly determine individual element properties such as mass, electron number, electron configuration, and unique chemical properties.
Non-metallic elements in the periodic table include hydrogen, carbon, nitrogen, oxygen, phosphorus, arsenic, and selenium.
Metals are minerals found underground in rocks, such as iron or lead. Heat is used to separate these from the rocks. Metals are extremely useful.
The periodic table is significant because it is organized to provide a wealth of information about elements and how they relate to one another in a single, easily accessible reference.
The table can be used to predict the properties of elements, including those yet to be discovered.
Considering their valence electrons, the alkali metals and halogens are the two most reactive groups of elements.
Thus, the correct option is C.

Cell theory states that all living things contain one or more cells. Why do you think cell theory meets the definition of
a scientific theory? Do you think it should be a scientific law?
Answer:
Cell theory meets the definition of a scientific theory because it can be proven, it has been tested for a long period of time and therefore there are many evidences that support the theory but not enough to become a law. Well scientific laws are statements based on repeated experiments or observation, but also, a law is something that always applies under the same conditions. Evolution occurs in the characteristics of living things within a species overtime. . A theory is much more complex: it explains why something happens. A law only describes what happens.

How does photosynthesis take place? need detailed explanation
Answer:
Photosynthesis takes place inside plant cells in small objects called chloroplasts. During photosynthesis, Plants get carbon dioxide from the air through their leaves, and water from the ground through their roots. Light energy comes from the Sun. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.

Explain how all the properties of water are related. Provide an example to describe the interconnectivity of each property. Be sure to include hydrogen bonding, polarity, surface tension, capillary action, cohesion, adhesion, high specific heat, and expansion upon freezing.
Answer:
The main properties of water are its polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling. A water molecule is slightly charged on both ends. This is because oxygen is more electronegative than hydrogen. The stream of water bends due to the polarity of water molecules.
All the properties of water are related to one another by the polar nature that is caused by the partial electronegativity difference of the hydrogen and oxygen molecules of water molecules.
A water molecule has uneven distribution of charges between different atoms of the different molecules. All types of properties of water due to attractions between these polar molecules.
in water molecules slightly negative atoms of one molecule are attracted to the slightly positive atoms of other moleculesthe attraction forms hydrogen bonding, weak bonds between a hydrogen atom and another atomProperties of water due to polarity and hydrogen bonds:
surface tension - a measure of the force necessary to stretch or break the surface of a liquidcapillary action - the tendency of water to rise in a thin tubecohesion - water attracted to other water moleculesadhesion - Water attracted to other materialshigh specific heat - the amount of the heat that must be absorbed or lost for one gram of the substance to change its temperature by 1°Cexpansion upon freezing - ice is less dense than and on freezing it expands its structure and forms a cage-like structure.Learn more about the properties of water:

Why is graphing the biomes a good way to assess average annual precipitation
and temperature?
Answer:
Explanation:
The different climates of the Earth are governed by their average annual precipitation and temperature. By plotting a graph (as shown below) of the relationship of these two variables we can determine a region where similar types of organisms can exists no matter where the biome occurs on the planet.
Graphing biomes is a good way to assess average annual precipitation and temperature because biomes depend on climate and climate change occurs due to changes in annual precipitation and temperature.
What is a biome?A biome is a place that is defined by the type of organisms present there. The temperature, soil, and presence of water and food are unique in a biome that makes suitable conditions for species.
Graphing a biome can tell us which animals are living there, and the changes in the environment of a biome can tell about the changes happening in the lives of the organisms.
Thus, because biomes depend on climate and climate change is a result of variations in yearly precipitation and temperature, graphing biomes is an effective technique to evaluate average annual precipitation and temperature.

how could measure whether or not the chemical reaction that breaks down hydrogen peroxide is occurring
Answer:
You could check the pH!
Explanation:
This is an idea, when you break down H2O2 (Hydrogen peroxide) you will be left with H2O (Water) and O2 (Oxygen gas). H2O2 theoretically would have a lower pH than water. Water has an average pH of around 7 while H2O2 will have a pH of about 4.5.
So theoretically to figure out if hydrogen peroxide is being broken down you can test for the pH. This is a very simply process, you just stick a little peice of litmus paper into the solution and immediatly it will change color to tell you the pH.

Only anaerobic respiration would take place in the absence of photosynthesis, hence option B is correct.
What is the relation between cellular respiration and photosynthesis?Oxygen and glucose are used in cellular respiration to create carbon dioxide and water. The equation for photosynthesis is the inverse of the equation for cellular respiration, further emphasizing this concept.
The cycle of cellular respiration and photosynthesis is essential for the survival of humans, animals, and plants. The term "cellular respiration" describes a chain of metabolic processes that convert glucose into water and carbon dioxide and ATP.
Therefore, in the absence of photosynthesis, there would be no glucose or oxygen for respiration, and since photosynthesis requires carbon dioxide, only anaerobic respiration would be possible.
