Behaviors have both an innate component and a learned component. Behavior is shaped by natural selection. Many behaviors directly increase an organism's fitness.
The idea of herbal choice is that traits that can be passed down permit organisms to conform to the environment higher than other organisms of identical species. This enables better survival and reproduction as compared with different individuals of the species, main to evolution. The character benefits by helping the institution, due to the fact the organization reciprocates by using supporting the character. Such cooperation strategies grow the assets necessary for survival that the organization can accumulate.
Mating conduct and defending Territory. a number of the most critical animal behaviors contain mating. Mating is the pairing of an adult male and girl to supply younger. Adults that are maximum a success at attracting a mate are maximum probably to have offspring. Behaviors associated with duplicates are essential members of the evolutionary achievement of organisms.

walks 2.0 miles in 18
minutes. What is
his speed in
km/hr? Use 1 mile =
1.609 km and
round to 1 decimal
place
The speed of Lucy the Bernese Mountain Dog is 10.7 km/hr.
Speed is the time fee at which an object is transferring along a course, whilst velocity is the charge and route of an item's movement. put some other way, the pace is a scalar value, at the same time as the speed is a vector.
Speed is defined as the rate of change of function, what we understand by way of pace is the importance of using which an object is shifting, or scientifically speaking the price at which an object is converting its role per unit time is known as the speed of the item.
Given,
1 mile = 1.609 km
or 1 mile = 1.6 km (round to 1 decimal place)
∴ 2 mile = 3.2 km = 3200 m
time = 18 minutes = 1080 second
Speed = distance / time
= 3200m / 18 minutes
Speed in km/hr = (3200m/1080 s) × 18/5
= 10.7 km/hr

Which of the following uses carbon from glucose as both an electron donor and an electron acceptor?
anaerobic respiration
aerobic respiration
fermentation
A & B
B & C
Aerobic respiration and fermentation use carbon from glucose as both an electron donor and electron acceptor.
What is aerobic respiration?
The process of aerobic respiration, which takes place in the presence of oxygen and converts glucose into ATP (Adenosine Triphosphate), gives the cell energy.
The procedure includes several phases, such as glycolysis, acetyl coenzyme A synthesis, citric acid cycle, electron transport chain, etc.
Carbon dioxide, water, and ATP energy molecules are the byproducts of aerobic respiration. A chain of electron donors and acceptors is involved in the electron transfer process.
Therefore, Aerobic respiration and fermentation use carbon from glucose as both an electron donor and electron acceptor.

Breathing rate will increase to expel the excessive

In the long term, physical conditioning and heat acclimation lead to increased perspiration during heat stress, lower skin, and core temperatures during exercise, and cutaneous blood flow needed to regulate body temperature.
There is a direct positive correlation between respiratory rate and heart rate. The faster the heart beats, the more breathing is done. When your heart beats faster, it uses more energy and delivers more oxygen to your body.
As you exhale, exhale carbon dioxide and begin a new breathing cycle. Carbon dioxide is constantly produced in the body, and by breathing, the carbon dioxide accumulated in the body is exhaled. The more activity we do, the more carbon dioxide we produce.

Answer:
Being wrong is a part of Science because in Science you won't know everything. In Science we use hypotheses or we guess what we think will be the results. It's okay to be wrong because you can learn by experimenting and discovering new things. People make new discoveries and also scientists or people who work in the field of science aren't always correct either. It is important to be wrong sometimes because you can learn new things. Science has a whole process and it can change what you thought would be right. Being wrong in Science or learning from being wrong can be helpful because people in the future can then know the reasoning to why that is the answer. It is an essential thing honestly.

Below are the reduction half reactions for chemolithoautotrophic nitrification, where ammonia is a source of electrons and energy and oxygen is the terminal electron acceptor.
NO2- + 6e- -> NH4+ (+0.34 volts)
O2 + 4e- -> 2H2O (+0.82 volts)
Using the information given, calculate the ΔE for this reaction, balance the full reaction to determine the n, the number of electrons transferred when 193 moles of NH4+ are oxidized. Finally, use the simplified Nernst Equation
ΔG = -nFΔE, where F = 96.5 kJ (mol e- × V)-1
to determine the Gibbs Free energy available to do work!
ΔG = -nFΔE, The Gibbs free energy for the given reaction is - 20859. 44
What is Gibbs free energy?
Gibbs free energy shows entropy and enthalpy of reaction.
NO2- + 6e- -> NH4+ (+0.34 volts)
O2 + 4e- -> 2H2O (+0.82 volts)
In the above equation, ΔE= 0.34 + 0.82 volts= 1.12 volts.
ΔG = -nFΔE
n= 193 moles,
F= 96.5 KJ
ΔE =1.12 volts.
ΔG = -nFΔE
= - 193 * 96.5 * 1.12
= - 20859. 44

Do plants die becuase of too much sun or too much water??
Answer:
They can die from both
Explanation:
Plants need sun but too much sun can dehydrate or damage the plant. As if too water plants need air too breath so adding too much water can drown them
Answer:
Both
Explanation:
Plants harvest energy from the sun with the help of chlorophyll and carotenoid, two photon-capturing molecules. But if the plants are exposed to too much sun, these molecules absorb more energy than they can handle and generate reactive species of oxygen that can destroy the plant.
and
Roots growing in waterlogged soil may die because they cannot absorb the oxygen needed to function normally. The longer the air is cut off, the greater the root damage. The dying roots decay and cannot supply the plants with nutrients and water. Damage caused by over watering is frequently misdiagnosed as pest damage.

What is the momentum of a body?
Linear momentum, translational momentum, or simply momentum is the product of an object's mass and velocity in Newtonian physics. It is a vector quantity with magnitude and direction. If m is an object's mass and v is its velocity (also a vector quantity), then p = mv is the object's momentum.

What conditions are needed to form organic molecules from inorganic molecules
Answer:
Presence of inorganic molecules with lightning and intense radiation
Explanation:
This process of the formation of organic molecules from inorganic molecules is called abiogenesis. It is believed that this is how the first organic molecules were created in early earth about 3.8 billion years ago. The classic 1952 Miller–Urey experiment attempted to replicate the condition of the early earth. They replicated lightning strikes (using electric parks) in a glass with greenhouse gases believed to have been the major constituents of early earth's atmosphere like methane. They were able to form primitive organic molecules from this experiment.

What are types of prevailing winds ?There are three types of prevailing winds:
Trade windsPrevailing westerliesPolar easterliesThe air over land in the coastal areas which heats up more faster during the day and begins to rise. Hence it results in low pressure at the surface. As warm air rises this air enters from sea. As a result wind direction during the day is from sea to land.
