Deserts typically have average daytime temperatures of around 100°F, while the average daytime temperature in tropical rain forests is around 85°F. However, the average monthly temperatures in the desert are lower than the average monthly temperatures in a rain forest. Explain the reason for this difference.
Answer: The temperature of the rainforest does not experience a drastic fall as in the case of the desert.
Explanation:
In the desert the average daytime temperature remains 100°F and that of the rainforest is 85°F. But average monthly temperatures are lower in the case of desert as compared to the rainforest although the vegetation cover is higher in rainforest as compared to desert so humidity is also more. During night in desert temperature drops to an average of 25°F whereas in rainforest during night temperature level does not drop much it drops to only 71°F. Therefore, the average monthly temperature on desert is lower than rainforest.

Various factors influences the fluidity of the phospholipid bilayer of the cell membrane. If we were to chart the composition of cell
membranes in organisms as we move north from the equator to higher latitudes around the Arctic circle, we would expect to find
phospholipids with
A)
fewer hydrophilic heads.
B)
fewer interspersed cholesterol molecules.
both saturated and unsaturated fatty acid tails.
D
an increase in the length of the fatty acid tails.
Answer:
D
an increase in the length of the fatty acid tails.
Explanation:
As average annual temperatures decrease, we would expect to find phospholipids within the cell membranes of organisms to have both saturated
and unsaturated fatty acid tails. Saturated fatty acids tails are arranged linearly, in a way that maximizes interactions between the tails and
decreases bilayer fluidity. Unsaturated fatty acids, on the other hand, have more distance between the tails, fewer intermolecular interactions and
more membrane fluidity. Longer tails and decreased cholesterol also decrease fluidity
How does gas exchange occur in plants?
Plants obtain the gases they need through their leaves. They require oxygen for respiration and carbon dioxide for photosynthesis.
Explanation:
The gases diffuse between the cells spaces of the leaf through pores, which are normally on the underside of the leaf - stomata. From these spaces they will diffuse into the cells that require them.
(8.9B) A student made a chart to classify plates by the types of boundaries. What crustal
feature is most likely found between the South American and African plates? *
A Folded mountain
B Ocean trench
C Mid-ocean ridge
D Fault
Answer:
folded mountain
hope it will help you
The crustal feature is most likely found between the South American and African plates is folded mountain. The correct option is A.
What is folded mountain?When two or more of the tectonic plates of Earth are forced together, fold mountains are formed.
Rocks and debris are bent and folded into rocky outcrops, hills, mountains, and entire mountain ranges at these interacting, compressing limits. Orogeny, a process, is what produces fold mountains.
While having a narrower width than their length, fold mountains are very long.
Concave and convex slopes are typically present on opposite sides of fold mountains. Most fold mountains are located on the edges of continents that face the ocean.
A student created a chart to categorize plates according to the different boundary types. The folded mountain is most likely the crustal feature that lies between the South American and African plates.
Thus, the correct option is A.

- What is the geocentric model of the
universe?
a) The Theory of Evolution
b) Newton's Laws of Motion
c) The belief that Earth is at the center of our solar system
d) Superstition
Answer:
I believe C,
Explanation:
The geocentric model of the universe maintained that the Earth was at the center of everything in the solar system. In it, the Sun and planets orbited around our planet. Many odd and elaborate adaptations were required to make this model agree with observations. This problem increased, as our our observations got more accurate.
The geocentric model was superseded by the heliocentric model, in which the planets all orbited the Sun. The Heliocentric model was eventually able to show that the positions of the planets over time were much more convincingly, and simply portrayed by it, than by the former model.
Apologizes if I'm wrong/
Answer: It is c because the person who made it or thought of it said that the earth is at center of the cosmos or the universe.

Answer:
D.Para la mayoría de los ecosistemas la energía proviene de la luz
Explanation:
Los ecosistemas requieren de un suministro constante de energía para poder sustentar la vida. A excepción de ecosistemas basados en fuentes hidrotermales, en general este aporte energético proviene del sol que suministra energía lumínica la cual es convertida por los organismos productores (por ej., plantas y algas) en compuestos orgánicos. Los productores representan la fuente de energía y alimento de consumidores primarios (por ejemplo, herbívoros), los cuales a su vez sirven de sustento para consumidores secundarios (por ej., carnívoros), estos suministran de alimento a los consumidores terciarios y así sucesivamente. Finalmente, los descomponedores son aquellos microorganismos que se alimentan de los restos orgánicos obtenidos a partir de productores y consumidores.
The larvae of potato beetles cover themselves in their own feces to avoid being consumed by predators. What system produces feces?
Answer:
Explanation below
Explanation:
Hemisphaerota cyanea, also known as the palmetto tortoise beetle, is a type of leaf beetle that cover themselves with their own feces, just to persuade most predators to pass them by. This form of outrageous defense, developed by the crafty beetle, was discovered by biologists at the Cornel university.
The feces comes out of the hindgut of the beetle, fashioned like golden strands, which can be used to protect the vulnerable body of the beetle.

how does respiration take place in insects?
Answer:
please give me brainlist and follow
Explanation:
Instead of lungs, insects breathe with a network of tiny tubes called tracheae. Air enters the tubes through a row of holes along an insect's abdomen. The air then diffuses down the blind-ended tracheae. Since the biggest bugs have the longest tracheae, they should need the most oxygen to be able to breathe.
what process is responsible for the absence of glucose and amino acids in urine
Answer:
The force of hydrostatic pressure in the glomerulus (the force of pressure exerted from the pressure of the blood vessel itself) is the driving force that pushes filtrate out of the capillaries and into the slits in the nephron
Selective reabsorption can be considered the process responsible for the absence of glucose and amino acids in urine.
What is selective reabsorption?The selective reabsorption mechanism allows the absorption of different substances including glucose and amino acids in the urine.
This reabsorption occurs after filtration in the capillaries of the urinary system. The filtration and excretion of waste substances are associated with the formation of urea.In conclusion, selective reabsorption can be considered the process responsible for the absence of glucose and amino acids in urine.

Answer:
La falta de células cono en la retina
Explanation:
En vertebrados, la retina se encuentra formada por dos tipos básicos de células denominados células conos y células bastones. Las células cono son unas células fotosensibles las cuales forman una capa concentrada en el centro de la retina. Estas células (células cono) son responsables de la distinción entre diferentes colores del espectro de luz visible. Las células cono se clasifican en tres tipos de acuerdo a su sensibilidad para distinguir la luz azul, roja, y verde. Esta sensibilidad se debe a la presencia de diferentes tipos de proteínas opsinas, las cuales confieren la capacidad de absorber la luz en una longitud de onda particular: cianopsina (sensible a la luz azul), eritropsina (sensible a la luz roja) y cloropsina (sensible a la luz verde). Animales como los gatos y los perros son daltónicos, es decir, no pueden completamente diferenciar los colores, debido a la falta de una o más clases de células cono (y por lo tanto también de opsinas) en la retina.

Recombinant DNA technology involves which sequence of steps?
Answer:
B
Explanation:
Processes of recombinant DNA technology involve isolation of DNA of the desired DNA fragment. In order to cut the DNA with restriction enzymes, it needs to be in pure form, free from other macromolecules. The DNA is enclosed within the membranes, we have to break the cell open to release DNA along with other macromolecules such as RNA, proteins, polysaccharides, and also lipids. This can be achieved by treating the bacterial cells/plant or animal tissue with enzymes such as lysozyme (bacteria), cellulase (plant cells), chitinase (fungus). The RNA can be removed by treatment with ribonuclease whereas proteins can be removed by treatment with protease.
What are the behavioral adaptions of an animal from the ocean, animal from the desert, animal from antartica and animals from rain forest
Answer:
1. Some fish like stargazer fish hide in rocks and sand to catch prey; some paralyze other fishes or some other ocean animal for safety and food, some like remora fish attach to larger fishes like sharks for protection and food.
2. Some desert animals like kangaroo rats can survive their whole lives without drinking water as they obtain all the moisture they need from the food in their diets.
3. Emperor penguins found in Antarctica form large, ever-moving huddles that allow them to share body warmth, and shelters them from the cold wind.
4. The sloth, an animal found in treetops uses camouflage and moves very slowly to make it difficult for predators to spot.
Explanation:
Adaptation refers to characteristics that help an organismmto be better suited for survival in their environment. Some adaptations may be physical such as the possession of limbs for movement by some animals, physiological such as production of toxins by some plants to avoid being eaten, or behavioural such as building a nest by birds
1. Fishes are animals that live in the ocean. Behavioural adaptations are the way different fish act to survive. Some fish like stargazer fish hide in rocks and sand to catch prey, some paralyze other fishes or some other ocean animal for safety and food, some fish like remora attach to larger fishes like sharks for protection and food.
2. Animals from the desert adapt to the hot desert environment by only coming out at night while hiding in burrows during the day. Some desert animals like kangaroo rats can survive their whole lives without drinking water as they obtain all the moisture they need from the food in their diets.
3. Antarctica is found in the world's coldest region, the South pole. Animals found in this region show various adaptations in order to survive the extreme cold conditions. Antarctic animals have unique behavioural adaptations that help them survive the harsh winter. Emperor penguins found in Antarctica form large, ever-moving huddles that allow them to share body warmth, and shelters them from the cold wind.
4. The rainforests are known for plenty of rainfall, abundance of animal and plant life. Due to these unique characteristics of the rainforests, animals have learnt to survive due to the competition for food and abundance of predators. The sloth, an animal found in treetops uses camouflage and moves very slowly to make it difficult for predators to spot.

how is the air outside the cell different after photosynthesis than it was before?
Photosynthesis is a process by which plants take carbon dioxide, water, and sunlight from the atmosphere and release oxygen into the air. This results into decreasing the temperature of atmosphere and maintain concentration of gases.
What happens during Photosynthesis?
Plants consume carbon dioxide, which is a greenhouse gas through the process of photosynthesis. This process involves reduction of carbon dioxide in the atmosphere which has an indirect cooling effect on the atmosphere. Plants cool the atmosphere as they release water vapor when they get hot, by a process which is similar to sweating.
About 70% of the oxygen in the atmosphere which we breathe comes from the photosynthesis of plants and algae in the ocean. Atmospheric oxygen from photosynthesis also maintains the ozone layer, which protects living organisms from harmful ultraviolet (UV) radiations which comes from the Sun.

What is Transcription?The process in which information of a strand of DNA is copied into a new m RNA molecule is known as Transcription.
The enzyme responsible for transcription is RNA polymerase. Transcription start when RNA polymerase binds to a promoter region at the start of a gene directly or through helper proteins. Initiation, Elongation, and termination are the three steps of transcription. Transcription is carried out with the help of enzyme RNA polymerase and some proteins known as transcription factors. Enhancer and promoter sequences are the DNA sequences on which transcription factors attach to initiate the transcription process by directing RNA polymerase to the correct transcription site.The transcription initiation complex is made up of transcription factors and RNA polymerase working together.
