Why do you think scouts could hear better through the solid ground rather than
through the air?
Answers
Answer:
Sound travels better through solids than through air.
Explanation:
Think about being in the pool: you can hear a lot of things, albeit muffled a little. Or think about tapping a really long pole, and someone standing far away can hear the vibration or the noise while touching the pole.
Solids are more tightly packed together. Sound needs a medium to travel though, and anything with densely packed atoms is better than loosely packed. The hierarchy is solid > liquid > air. Kinda funny that we do most of our talking through air.

The deforested land will not be able to support large trees again.
Some species will develop adaptations to survive in the deforested land.
Some populations will migrate out of the deforested area.
Some animals will instantly adapt to the deforested environment.
Answers
Answer:
Some species will develop adaptations to survive in the deforested land.
Some populations will migrate out of the deforested area.
Explanation:
The deforested land will be able to support large trees eventually in the future, and animals cannot instantly adapt to anything.
Therefore, the most logical answers are populations will migrate to forest lands and species will eventually develop adaptations to help them in the newly deforested land.

The first step in the metabolism of triacylglycerols is the hydrolysis of the ester linkage by a lipase. Three different lipases play major roles in triacylglycerol metabolism in animals:
pancreatic lipase (a water‑soluble lipase secreted into the intestine), lipoprotein lipase, and hormone‑sensitive lipase.
a) For the given statements, identify which lipase best fits the description. If none of the lipases apply, choose "none of the lipases."
1. This enzyme hydrolyzes adipose triacylglycerols.

what is the relationship between peripheral resistance and blood pressure ? between blood viscosity and blood pressure
Answers
Answer:
Peripheral vascular resistance (systemic vascular resistance, SVR) is the resistance in the circulatory system that is used to create blood pressure, the flow of blood and is also a component of cardiac function. When blood vessels constrict (vasoconstriction) this leads to an increase in SVR.
The relationship between BP and viscosity is such that, given a constant systolic BP, if blood viscosity increases, then the total peripheral resistance (TPR) will necessarily increase, thereby reducing blood flow. Conversely, when viscosity decreases, blood flow and perfusion will increase.
can someone write me a small introduction about reflexes
Answers
reflex is an involuntary or automatic, action that your body does in response to something — without you even having to think about it
reflex action often involves a very simple nervous pathway called a reflex arc. A reflex arc starts off with receptors being excited. They then send signals along a sensory neuron to your spinal cord, where the signals are passed on to a motor neuron

A large population of fish live in a lake. The color of their scales is determined by two different alleles of the autosomal S gene, S1 and S2. Homozygous S1S1 fish have yellow scales, S2S2 homozygotes have blue scales, and S1S2 heterozygotes are green. Scientists caught 100 fish at random and recorded their color. Among those 100 fish were 30 yellow, 50 blue, and 20 green ones. After the original sample was analyzed, an asteroid landed in the lake and killed all the fish that happened to be in one particular location. When 100 fish were sampled again, 15 were yellow, 75 were blue, and 10 were green. Was the fish population in Hardy-Weinberg equilibirim (HWE) before the asteroid hit? In an ideal population, how many generations would it take to establish HWE after the asteroid hit?
Answers
Answer:
Yes it was
two generations
Explanation:
H0: population is in Hardy-Weinberg equilibrium
Ha: population is not in Hardy-Weinberg equilibrium
P(S1) = (2×obs(S1S1) + obs(S1S2))/(2×fish(S1S1)+2×fish(S1S2) +2×fish(S2S2) )
P(S1)= (60+50)/(60+100+40)
P(S1)=0.55
P(S2)= 1-P(S1)
P(S2)= 0.45
Exp(S1S1)= 0.55×0.55×100=30.25
Exp(S1S2)= 2×0.45×0.55×100=49.5
Exp(S2S2)= 0.45×0.45×100=20.25
x²=∑ (Observed-Expected)²/ Expected
= (30-30.25)²/30.25 + (50-49.5)²/49.5+ (20-20.25)²/20.25
= 0.010203
The value at 5% significance level and degree of freedom 1 from table is 3.84. Since x² value is less than value we accept null hypothesis
It takes two generations to achieve Hardy-Weinberg equilibrium if conditions of Hardy-Weinberg are met.
Identify the incorrect statement(s) describing Primary and Secondary succession: Select one or more: a. primary succession is the process in which species gradually or rapidly establish a new ecosystem, following a drastic stochastic environmental disturbance event b. species establish new ecosystems based upon defined ecological assembly rules, where new niches are occupied and organized across trophic levels, based on the genetic heterozygosity and unique adaptations of individuals c. volcanic eruptions, fires and floods can lead to succession events, with remaining survivors becoming the founding populations of the altered habitats and landscapes which remain d. through primary succession, mosses and detritivores convert new landscapes, followed by annual, perennial grasses, flowering plants, and finally, trees which provide habitat for detritivores, producers and consumers to enrich a diverse ecosystem
Answers

What is the main cause of an aurora?Arrange the inner layers of the Sun in order starting with the innermost layer.
Answers
Answer:
i.Core:The center of the Sun where all the Sun's energy is produced.
ii.Radiative Zone:Tiles Energy produced by nuclear reactions in the core travels to this zone through radiation.
iii.Convection Zone:In this zone, hotter gases from the base travel to the top and cooler gases sink to the bottom due to the temperature difference.
iv.Photosphere:This zone is visible from Earth. Sequence
When charged particles from the sun strike atoms in Earth's atmosphere, they cause electrons in the atoms to move to a higher-energy state. When the electrons drop back to a lower energy state, they release a photon: light. This process creates the beautiful aurora, or northern lights. ~Earthsky

Based on Kepler's observations about planetary motion, what is the relationship between a planet's orbital velocity and its distance from the sun?
Answer is the greater the distance, the slower the orbital velocity..
I do not understand it. Can someone please explain it to me? Thank you!
Answers
Answer:
Explanation:
The closer the planet is to the sun,the faster it moves because the suns gravitational pull is stronger.The answer tells you that the greater the distance,the slower the planet will rotate
Kepler laws of planetary motion can be stated as planets move around the sun in elliptical orbits, the radi joins the planets to sun leaves out equal areas to equal intervals in the equal lengths of time.
The planets that are farther away from the sun have slow velocity and longer paths such as pluto. These factors make it longer for one complete revolution.Thus greater will be the distance the slower will be the velocity of movement such as that of mercury and pluto. As sun gravitational pull will be weaker.Learn more about the Kepler's observations about planetary motion.

What is the advantage for birds of not having a bladder?
Answers
Answer:
Explanation:
The urinary bladder is a flexible sac that can expand and contract and that holds urine.
Urea is excreted mainly by birds and it happens to be the main chemical in urine, without the water in it, the birds excrete just solid droppings instead of as a liquid.
Now, birds physiology is such that they have only one opening to get rid of their (solid) waste and they do not have a bladder.

What biological process releases carbon dioxide back into atmosphere?
Answers
Explanation:
Respiration is the type of biological exercise that raises Co₂ concentration in the atmosphere.
Explanation:
RESPIRATION is said to be the basic biological and metabolic process that is essential for all living beings for their survival and growth with nourishment.
Cells are the basic unit of living organisms that undergo cellular respiration. In this process, oxygen is in taken and carbon dioxide is respired out which adds the concentration of the carbon dioxide from the atmosphere.
In the process of respiration, the living cells of the organism produce energy by the intake of oxygen for the oxidation of complex organic substances and expires out the carbon dioxide.
