Determine which of the following statements is true about energy in ecosystems A. Consumers pass on 20% of the energy they get from a lower trophic level. OB. Primary consumers lose 60% of the energy they absorb from producers as urine and feces. C. 10% of the energy Primary consumers absorb is lost as heat. Ons Primary producers lose 20% of the energy they absorb as urine and feces.
Answer: C. 10% of the energy Primary consumers absorb is lost as heat.
Explanation:
According to the ten percent law of energy flow only 10 percent energy is transferred from one trophic level to the next trophic level and rest of the energy is used to develop the biomass and lost as heat. As the loss of heat is an essential exothermic reaction after the digestion and assimilation of food the energy is lost as heat from the body of the primary consumers is 10%. Primary consumers are animals that are dependent on plants for their food requirements for example deer, goat and others.
do thyroid hormones influence heart rate from influencing the heart itself, or the attached to it?
Answer:
An excess of thyroid hormones increases cardiac contractility and resting heart rate (see box below). Cardiac output may increase by 50-300 per cent as a result of the combined effect of increases in resting heart rate, contractility, ejection fraction and blood volume, with a concomitant decrease in SVR.
Transfer RNA has __________ bases attached to one end of the molecule and an amino acid to the other.
Answer:
Nitrogenous
Explanation:
Transfer RNA, also known as tRNA, is one of the three types of RNA. It is involved in the translation process. The shape of the tRNA allows it to be a very important component of the translation process.
The morphological structure of the tRNA is in such a way that a sequence of nitrogenous bases called ANTICODON attach to one of its ends while an amino acid is attached to the other end. This way the tRNA molecule is able to read the mRNA codon using its anticodons and carry the corresponding amino acids.
N.B; the anticodons are composed of three nitrogenous bases just like codons. Codons are complementary to anticodons.

In a population of mole-rats, some have a little larger teeth and longer claws. If those particular mole-rats survive because they can dig quicker and the others are preyed on and do not survive to reproduce, what will eventually happen in subsequent generations?
Answer:
One increase in population and the other decrease.
Explanation:
The population of the rats having little larger teeth and longer claws increases as compared to those rats having small teeth and shorter claws because the rats can escape from their predators and survive in that environmental conditions. The population of rats having small teeth and shorter claws extinct in the end due to no reproduction and preyed by the predators and dominated by the population of the rats having little larger teeth and longer claws due to their features.

Leaf is modified into thorn where water availability is low.....give reason?
Answer:
To help conserve water or prevent loss via transpiration from the leaves
Explanation:
Some plants are found growing in habitats with little or no moisture content as annual rainfall is very low. These plants are called xerophytic plants. However, despite the low water condition, these plants are adapted to the environment and still survive.
One of their adaptation (structural) is that their leaves are reduced to thorns. Ideally, plants tend to lose water via the stomata on the leaves in a process called TRANSPIRATION. Hence, the leaves of plants adapted to a xerophytic habitat is modified to thorns in order to prevent water loss from the leaves and conserve the water.
Why dont plant cells have microvilli?
Answer: They don’t have microvili because they don’t need it.
Explanation:
Animal cells have this because it increase surface area and helps absorb food and water molecules.
Plant cells do not have microvilli because they do not require the same type of surface area enlargement as animal cells.
Microvilli are small, finger-like projections that extend from the surface of animal cells. They help to increase the surface area of the cell, which is important for functions such as absorption and secretion.
Whereas plant cells have a rigid cell wall that provides structural support and protection. They have evolved unique structures to meet their specific needs, such as chloroplasts for photosynthesis and a cell wall for support and protection.
So, the absence of microvilli in plant cells is not a disadvantage since they do not require the same surface area enlargement as animal cells.
Therefore, the absence of microvilli in plant cells is due to their unique structural and functional needs.

Which of the following adaptations enables deciduous trees to produce more food?
a.
broad leaves
b.
thick bark
c.
leaf loss
d.
color change
The presence of broad leaves, which is present in Option A, enables deciduous trees to produce more food. Broad leaves have the benefit of increasing the photosynthetic rate, resulting in more food production.
What is the role of the leaves?Leaves are of many types, such as the neddle-shaped leaf and flat leaves, and all these leaves are adapted to different climatic conditions. The plants that are present in the tropical area have comparatively flat leaves compared to those that are present in the cold areas in order to control transpiration and heat.
Leafy plants that are green in color have chloroplasts and chlorophyll pigments that help in the photosynthesis process. Because the photosynthesis process produces food, if the leaf is green, it has more chloroplasts and thus produces more food.
Hence, The presence of broad leaves, which is present in Option A, enables deciduous trees to produce more food.

Which greenhouse gas has an average lifetime in the atmosphere of a few weeks to thousands of years and is the largest contributor to climate change?
Answer:
Greenhouse gases from human activities are the most significant driver of observed climate change since the mid-20th century.1 The indicators in this chapter characterize emissions of the major greenhouse gases resulting from human activities, the concentrations of these gases in the atmosphere, and how emissions and concentrations have changed over time. When comparing emissions of different gases, these indicators use a concept called “global warming potential” to convert amounts of other gases into carbon dioxide equivalents.
Explanation:
Why does it matter?
As greenhouse gas emissions from human activities increase, they build up in the atmosphere and warm the climate, leading to many other changes around the world—in the atmosphere, on land, and in the oceans. The indicators in other chapters of this report illustrate many of these changes, which have both positive and negative effects on people, society, and the environment—including plants and animals. Because many of the major greenhouse gases stay in the atmosphere for tens to hundreds of years after being released, their warming effects on the climate persist over a long time and can therefore affect both present and future generations.

What are the positive effects human activities on vegetation?
Answer:
Vegetation cover is also significantly impacted by human activities. Changes in land use resulting from human activities such as urbanization and agriculture are important factors influencing the spatial pattern of vegetation.
Answer:
Vegetation plays a vital role in our natural ecosystem and also supports the biosphere in various ways; vegetation helps to regulate the flow of numerous biogeochemical cycles, most importantly those of water, carbon, and nitrogen; it also contributes in the local and global energy balances. With the continuous increase in the population, the negative impact of human activities on the ecological environment is also increasing, such as overgrazing caused by the rapid increase of livestock.

You are examining the data from two time points taken in an experiment. At time 1 there was an extracellular concentration of Na of 115 mM outside the cell and 8mM inside the cell. An amino acid, lycine, is at 20mM outside and 40mM inside. At the second time measured Na is 100mM outside the cell and 23 mM inside the cell. Lycine is 15 mM outside the cell and 45mM inside. What is the best explanation
Answer:
See the answer below
Explanation:
The best explanation would be that both Na and the amino acid lycine are simultaneously diffusing (in bound form) from the outside to the inside of the cell.
Considering the Na alone, one would see that the concentration outside the cell decreased in equal amount (15 mM) as the increase in the intracellular concentration of the same molecule.
Also considering the amino acid alone, the extracellular concentration increased by the same magnitude (5 mM) as the decrease in the intracellular concentration of the same molecule.
Hence, it could only be that both molecules bind together and diffused from the region of higher concentration (outside of the cell) to the region of lower concentration (inside).
does the gut flora affect digestion?
Answer:
Yes.
Explanation:
Our bodies need different organs to regulate our bodily functions, and the gut is no different. The gut flora helps us digest and break down the food we eat, along with producing various enzymes that help to break down carbohydrates. Also, after the carbohydrates are broken down, they can pass through the gut wall into the blood (just a little fun fact). The gut also helps to benefit our immune system. One last bit of information is that an imbalance of bacteria and microbes in our bodies may lead to weight gain, high blood sugar, high cholesterol, and many other terrible issues.

How is The processes of photosynthesis and respiration are interrelated
[tex]\color{Black}\huge{Answer} [/tex]
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.Answer:
Carbon dioxide and water are converted to oxygen and glucose through photosynthesis.
Oxygen and glucose are converted into water and carbon dioxide through cellular respiration.
By-products include water and carbon dioxide, while ATP is the energy generated by the process.
Explanation:
Plants use light water and carbon dioxide to make energy (glucose) and oxygen through photosynthesis. The oxygen is released into the atmosphere while the glucose powers the plant's operations. The process through which animals mix glucose and oxygen to make carbon dioxide and water is known as cellular respiration.
Photosynthesis end product is glucose utilised for the production of ATP in the cellular breathing. Glucose is then returned to carbon dioxide, needed for photosynthesis. During photosynthesis, the water is broken down into oxygen, but oxygen is mixed with hydrogen into water in cell respiration.
A population of rabbits has individuals with fur coloring that ranges from white to brown. The population lives in a temperate deciduous forest where the summers are mild and average about 50°F. The winters are often below freezing.
If warmer temperatures last longer into the fall and the average temperature in the winter is getting warmer, what do you expect to happen to the population?
The percentage of the population with brown fur will decrease.
The percentage of the population with white fur will decrease.
The population will increase in size, but the color percentages will remain unchanged.
The population will decrease in size, but the color percentages will remain unchanged.
Answer:
The best option for this problem would be the second option: "The percentage of the population with white fur will decrease"
Explanation:
Think about animals up in the north. Most of them are white because it helps them blend in the snow. And so an increase in average temperatures would mean less snow time. This would mean that the white rabbits will be more vulnerable to attacks for a longer time period of the year compared to previous years with a short time period of being vulnerable.
