The frequent use of a hot tub makes it harder for a couple to conceive a child because taking hot baths will heat the sperm cells and impair sperm cell functions.
The use of a hot tub while conceiving significantly led to the reduction of sperm count, sperm concentration (volume), and shape of the sperm (morphology).
Studies have shown that heat exposure can damage the DNA of a sperm cell. Therefore, to produce healthy sperm, men's testes need a cooler environment.
Staying in a hot tub raises the body temperature which has a negative effect on the male partner to make healthy sperm.
Also, for women, raising body temperature during early pregnancy may be led to birth defects or even miscarriage.

Q: Use the equation for aerobic respiration to explain why the air that you exhale contains more carbon dioxide than the air that you inhale.
The equation:
glucose + oxygen = carbon dioxide + water
The exhaled air incorporates extra carbon dioxide due to the fact the carbon dioxide produced in the course of respiration is removed out of the frame because the exhaled air throughout the method of respiration.
Whilst we exhale, we breathe out less oxygen but greater carbon dioxide than we inhale. The carbon we breathe out as carbon dioxide comes from the carbon in the food we eat.
For that reason, inhalation is while we take in air containing oxygen. similarly, exhalation is whilst we give out air rich in carbon dioxide. they're the basic process of respiration. expanded muscle hobby manner multiplied use of oxygen, elevated production of glucose-forming ATP and, consequently, elevated ranges of carbon dioxide. Carbon dioxide diffuses from the cells into the blood.

if you were to take slices of potato and place them in distilled water, what would happen to the cells?
The potato slice cells would swell due to osmosis.
Osmosis is the process by which a solvent moves between two solutions with various solute concentrations over a semipermeable membrane. The solvent is transferred from the solution with the lower solute concentration to the solution with the greater solute concentration during osmosis. The smallest pressure that, when given to the solution phase, prevents the solvent from permeating a semipermeable membrane into the solution is known as osmotic pressure.
Osmosis is primarily driven by the reduction in Gibbs free energy that occurs along with the dilution of the solution. Moving a solvent from a greater solute concentration to a lower solute concentration is the process of reverse osmosis. When hydrostatic pressure exceeds osmotic pressure, this occurs.

Answer:

Explanation:
B is the true line i think
Based on the given flowchart (Soil Roots→Plants → Animals), the process likely to be occurring in the plant's roots is: Nitrogen fixation. The correct option is D.
What is water transpiration?The evaporation of water from plants is known as transpiration. As much as 99.5% of the water received by a plant's roots is surplus water that transpires out of the plant rather than being used for growth or metabolism.
Additionally, the movement of water and nutrients from the roots to the shoots is accelerated by transpiration. As a result, transpiration mechanisms have an impact on the global carbon and hydrological cycles as well as the yield and survival of agricultural species.
This is because nitrogen fixation is the process where atmospheric nitrogen is converted into a form that plants can absorb through their roots and use as nutrients.

How does the reduced genetic diversity of small populations make them more vulnerable to extinction?
Reduced genetic variation decreases the capacity of a population to evolve in the face of change. the reduced genetic diversity of small populations makes them more vulnerable to extinction.
If genetic variety receives too low, species can pass extinct and be misplaced forever. that is because of the mixed consequences of inbreeding depression and failure to conform to trade. In such instances, the creation of recent alleles can store a population. Inbreeding, genetic drift, constrained gene waft, and small population size all contribute to a reduction in genetic diversity.
Populations with low genetic variety might not be capable of adapting to demanding situations including converting environmental conditions, shrinking habitats, or new diseases, that may position them at risk of disappearing. this is because some variations of a gene may be misplaced because of random threats, and that is more likely to occur while populations are small.

Explanation:
Cellular Respiration allows animals to generate energy by burning off fat. Cellular Respiration generates heat so that fat can be burned off.
Our brain receives more action potentials when our eyes are exposed to light even though our photoreceptors release more neurotransmitter in the dark. Propose an explanation.
Rod and cone cells use glutamate as their signal, and they release less glutamate when exposed to light. But as glutamate production declines, other retinal cells speed up the transmission of action potentials to the brain, resulting in more action potentials reaching the brain in light than in darkness.
When exposed to light, do photoreceptors release more neurotransmitters?Increases in light intensity cause photoreceptors to release less glutamate, which lowers the membrane's potential and results in hyperpolarization, while decreases in light intensity cause photoreceptors to release more glutamate, which raises the membrane's potential and results in membrane depolarization.What neurotransmitter are released by rods and cones?Rods and cones produce glutamate as a neurotransmitter.

Predict the number of signals expected in the proton spin decoupled 13c spectrum of p-dibromobenzene (1,4-dibromobenzene).
2 number of signals is expected in the proton spin decoupled 13C spectrum of p-dibromobenzene (1,4-dibromobenzene).
It is well known that the proton spin decoupled 13C spectrum of p-dibromobenzene (1,4-dibromobenzene) should show two signals. However, it has been recently reported that only one signal is observed in this spectrum.
There are two possible explanations for this discrepancy. Firstly, it is possible that the p-dibromobenzene molecule is not actually proton spin decoupled. In this case, the spectrum would only show one signal because the proton and carbon spins would be coupled together.
Alternatively, it is possible that the molecule is proton spin decoupled, but that the 13C signal is very weak and is only detectable when the molecule is in a very high energy state. This would explain why only one signal is observed in the spectrum.
Further experiments are required to determine which of these explanations is correct. In the meantime, it is important to be aware that the proton spin decoupled 13C spectrum of p-dibromobenzene may not show the expected two signals.

How does mass relate to inertia
Answer:
Inertia is directly proportional
Explanation:
Inertia increases as the mass of an object increases. Inertia is directly proportional to the mass, that is, inertia increases with the increase in the mass and decreases with the decrease in the mass. The SI unit of the mass is kg and the SI unit of the inertia is also kg.
Answer:
Objects with more mass have more inertia. Consequently, a very large rock will be harder to move than a small pebble. The same way, once the large rock starts to move, it will be harder to stop than the small pebble. MOMENTUM is a measure of inertia of motion. Then momentum relies on mass and velocity. We define momentum as the product of mass and velocity: m * v.

If auxin transport proteins were equally distributed at both ends of the cells, would polar auxin transport stiu be possible? Explain.
If auxin transport proteins were equally distributed at both ends of the cells, polar transport of auxin is not possible.
The polar transport of auxin is predominantly caused by directed IAA efflux out of the basal side of cells and is governed by chemical and electrical gradients across the cell membrane. It enters the cell via two different ways i.e. active uptake and diffusion. IAA that penetrates cells deprotonates in the cytoplasm's neutral environment and therefore can no longer diffuse across the plasma membrane because it is a charged molecule. IAA can travel down the electrochemical gradient and out of the cell thanks to efflux carriers that are concentrated on the basal side of the cell. Auxin travels along a file of cells in a single direction as a result of this polar efflux and therefore if the proteins are equally distributed at both the ends of the cells this polar transport is not possible.
