Moths and other insects collected around lights like lamps is a common sight, particularly in the summer. Frequently, organisms mesmerised by such a radiance die from overheating or are devoured by predators.
Are bugs blood-borne?Certainly, there is blood in insects, but it is not human blood. Human blood is red because of the presence of haemoglobin and is needed to transport oxygen throughout our bodies. In insects, blood carries nutrients but not oxygen throughout the body.
According to the "tergal theory," wings may have developed as gliding membranes on the tergum, the top of the insect body wall. The "pleural theory" contends that ancient leg segments that fused with the torso before ending up on the back gave rise to wings.

Determining rate in white light. Calculate rate of volume change for Elodea in white light. Record in lab data
Answers
The rate of volume change can be used to find out how different lights (different wavelengths) affect photosynthesis and plant growth. To calculate it, we just need to record data of volume change and time.
------------------------------------------------------
To determine the rate of volume change, you need to use the following formula.
Rate of volume change (mL/hr) = Final volume - Initial volume x 60
Time
\(\\ Rate of volume change (mL/hr) = ((Final volume - Initial volume)/ Time (min)) x 60 (min/hr) \\\)
To calculate the rate of volume, we will use the following data.
If these values are different from yours, you just need to replace them acoording to the data in your table.
Time (min) White light volume
0 3
5 4.3
10 5.6
15 6.9
20 8.2
So, according to these values
Final volume, Vf = 8.2 mLInitial volume, Vi = 3 mLTime, T = 20 minRate of volume (mL/hr) = ((Vf - Vi)/ T) 60
\(\\ Rate of volume (mL/hr) = ((Vf - Vi)/ T) 60\\\)
\(\\ Rate of volume (mL/hr) = ((8.2 - 3)/ 20) 60\)
\(\\ Rate of volume (mL/hr) = 15.6 mL/hr\)
The rate of volume change for Elodea in white light is 15.6 mL/hr.

ATP can be produced via two cellular respiration pathways. one that occurs in the presence of oxygen and one that occurs in its absence. Name and explain how these two mechanisms differ.
Answers
Aerobic and anaerobic respiration are the two different types of cellular respiration processes that are used to produce ATP.
ATP (adenosine triphosphate) is a molecule used by cells for energy storage and transfer. Two types of cellular respiration pathways are present for ATP production: aerobic respiration and anaerobic respiration. The primary difference between these two is the presence of oxygen.ATP production during aerobic respiration occurs in the presence of oxygen. This process occurs in three stages: glycolysis, the Krebs cycle, and oxidative phosphorylation. In the first stage, glucose is broken down into pyruvate, which is then moved to the mitochondria in the second stage, the Krebs cycle, where it is further processed. The last stage is oxidative phosphorylation, in which the electron transport chain and chemiosmosis use the energy generated to create ATP.Anaerobic respiration occurs in the absence of oxygen, and it is a less efficient method of ATP production. Anaerobic respiration begins with glycolysis, the same as aerobic respiration. Instead of moving to the Krebs cycle, pyruvate is transformed into lactate or ethanol. These pathways are not as effective at producing ATP, but they can supply ATP during periods of low oxygen. In summary, the main difference between these two pathways is the presence or absence of oxygen during the process.For more questions on adenosine triphosphate

The correct option defines homologous structures is:
D. Anatomically different structures found in multiple organisms that share a similar function and result from divergent evolution.
What are homologous structures?Homologous structures are those that have similar functions, but their structure is different in different organisms.
Examples are the forelimb of a whale, a human, and a bat.
The structure of the forelimb is different in given animals, but their functions are similar.
Homology happens due to divergent evolutions.
Thus, the correct option is D.

you and your friend in the school yard. you rest your ear against a metal leg of the swings while your friend gently taps on the leg. you hear the tapping. describe the wave produced bt tapping. is it a longitudinal wave or a transverse wave? Draw a model of the wave.
Answers
The wave produced by tapping on the metal leg of the swings is a longitudinal wave. Longitudinal waves have oscillations that occur parallel to the direction of wave propagation.
When your friend taps on the metal leg, it causes compression in the material. This compression then travels through the metal as a wave, with successive compressions and rarefactions. As the wave reaches your ear, it causes your eardrum to vibrate, and you perceive the tapping sound.
| | | | |
C R C R C
| | | | |
The "C" represents compression, and the "R" represents a rarefaction. The wave propagates from left to right, with each compression and rarefaction alternating in sequence. As you rest your ear against the metal leg of the swings, you are able to detect the longitudinal wave as it travels through the metal and into your ear.

A population of mice in a field contains 5000 individuals at the beginning of a study. During the course of 1 year 2500 new individuals are born and 1000 individuals die, such that the population size after 1 year is 6500. Assuming that annual per capita birth rate (b) and per capita death rate (d) do not change, what will the population size be after another year has passed
Answers
Answer:
The population size would be of 8,450 mice.
Explanation:
While the initial population of mice was 5,000 and there were 2,500 new births, the birth rate is 50% (2,500 / 5,000 = 0.5). Now, the 1,000 deaths, in turn, represent a mortality rate of 20% (1,000 / 5,000 = 0.2). In this way, at the end of the year, the number of mice became 6,500 (5,000 - 1,000 + 2,500).
Maintaining the same population growth rates, the number of new births would be 3,250 (6,500 x 0.5), and the number of deaths would be 1,300 (6,500 x 0.2), with which at the end of the second year the number of mice would be 8,450 (6,500 - 1,300 + 3,250).

Melody has a part-time job working in a greenhouse. The greenhouse has glass walls and ceiling and a dirt floor. Automatic sprinklers come on several times each day to keep the plants in the greenhouse moist. Melody notices that water droplets often appear on the glass walls and ceiling and run down to the ground, even when the sprinklers are turned off. This effect is much more obvious on cool, sunny days.

sunlight radiates into the glass house. the glass intensifies the rays, causing the temperature in the room to rise. any water caught in the room, even once the sprinklers are turned off, will get even more humid, causing condensation on the glass so it appears like fresh ran on the surface of the glass. hope this helps! :) now hurry up and turn this in before its late!!!!!

Answers
If you drink a large amount of water, your interstitial fluid may become hypotonic compared to your intracellular fluid.
Hypotonic solutions are those that have more concentrations of solvent and less amounts of solute as compared to another solution or cell placed inside it. The movement of solvent occurs out of these solutions. The osmotic potential of such solutions is high.
Interstitial fluid refers to the fluid present around the spaces between cells. This fluid is helpful in the transporting oxygen and nutrients to the cells and also is involved in waste removal. The fluid becomes lymph fluid as it enters the lymph vessels.
