Answer: You would expect 25 Kcal of energy stored in trophic level 4.
Explanation:
Energy flow in the ecosystem follows 10% law according to which 10% of the energy in the lower trophic level is transferred to the next trophic level.
In this example grass belongs to the first trophic level, producers.
Energy of grass=25000Kcal
Energy transferred to trophic level 2=10% of 25000=2500
10% of the energy in trophic level 2 is transferred to trophic level 3.
Hence energy at trophic level 3=10% of 2500=250Kcal
Energy transferred to trophic level 4=10% of energy in trophic level 3
=10% of 250=25Kcal
Energy to be stored in trophic level 4=25Kcal
Answer:
There will be 25 Kcal
Explanation:
The 5th - .01% out of 25000 is 2.5
The 4th - .1% out of 25000 is 25
The 3rd - 1% out of 25000 is 250
The 2nd - 10% out of 25000 is 2,500
The 1st - 100% out of 25000 is 25,000

What is the difference between the DNA of a dog and the DNA of a fly?
A. The strength of covalent bonds.
B. The sequence of nucleotides.
C. The strength of hydrogen bonds.
D. The type of sugar building blocks.
Answers
Answer:
B. The sequence of nucleotides.
Explanation:
Different proteins build up.
The difference between the DNA of a dog and the DNA of a fly is the sequence of nucleotides (Option B). All organisms have DNA in their cells.
Desoxyribonucleic acid (DNA) is a molecule that contains the instructions (i.e., the genetic material) required to build and maintain the homeostasis, i.e., the internal equilibrium, of an organism.
Structurally, this molecule (DNA) is the same in all organisms.
DNA is composed of two long chains of nucleotides linked together by hydrogen bonds. The linear order of these nucleotides (i.e., Adenine, Guanine, Cytosine, and Thymine) determines the type and amount of proteins that are synthesized from a genome.
In conclusion, the difference between the DNA of a dog and the DNA of a fly is the sequence of nucleotides (Option B).

A student calculated the average surface area-to-volume ratio of four different types of human epithelial cells. The results are shown in the table below. Based on the data, which type of cell would be best suited for lining the alveoli of the lungs, where diffusion of carbon dioxide and oxygen must occur very rapidly? Simple squamous cells Simple cuboidal cells Simple columnar cells Simple spherical cells
Answers
Answer:
There is no data attached to this question, however, the question can be answered based on general understanding of epithelium tissues.
The answer is Simple squamous cells
Explanation:
Epithelial tissues are those tissues that line or cover the surfaces of walls or structures. However, based on the one cell layer and their shape, which defines their function, epithelial tissues are classified into the following:
- Simple squamous
- Simple cuboidal
- Simple columnar
All the above have one cell layer. This question involves a student that calculated the average surface area-to-volume ratio of four different types of human epithelial cells. Based on the question, SIMPLE SQUAMOUS CELLS would be best suited for lining the alveoli of the lungs, where diffusion of carbon dioxide and oxygen must occur very rapidly.
This is because the simple squamous cells, which are shaped like the scales of a fish, are thin-walled flat cells. Hence, they are found or adapted to parts where where diffusion or filtration takes place e.g alveoli of the lungs

how do mountains influence climate?
Answers
Answer:
Explanation:
They affect climate by blocking wind and receiving more rainfall than low-lying areas. As air is forced over higher ground, it cools, causing moisture to condense and fall as rain. The higher a location is above sea level, the colder it is.
Answer:
Mountains can affect the climate of nearby lands. In some areas, mountains block rain, so that one side of a mountain range may be rainy and the other side may be a desert. Much of airborne moisture falls as rain on the windward side of mountains.

Answers
Answer:
The correct answer is - option B. A small space (chloroplast).
Explanation:
The chloroplast is the cell organelle present in a photosynthetic organism like plants and algae which helps in trapping light and store in energy-rich organic molecules.
Stroma is the site where ATP production takes place in the chloroplast during the photosynthesis process. In light-dependent reactions during photosynthesis, ATP is produced in The thylakoid.

Explanation:
A common test for liver function involves sprinkling sulfur powder onto a sample of urine (mostly water with dissolved bodily waste). Sulfur powder sprinkled on a sample from an Individual with impaired liver function will sink because the urine contains a high level of bile salts, while the sulfur powder sprinkled on normal urine samples will float.
Answers
Bile salts decrease the surface tension of the urine sample, that’s why the sulfur will sink in a sample from an individual with impaired liver function since it contains high levels of bile salts.
Bile salts caused the sulfur powder to sink because bile salts decrease the surface tension of the urine sample.
Liver function test are test procedures that are used to diagnose and monitor liver disease or damage.
When the liver is malfunctioning, such as in cases of hepatitis and cirrhosis, high level of bile salts are present in the urine. This is as a result of high serum bilirubin.
One of the fastest methods to carry out a test for liver function is sprinkling sulfur powder onto a sample of urine.
Surface tension is the quality displayed by water that enables substances of greater density float on it.
The bile salts is able to decrease the surface tension of the urine sample causing the sulfur powder to sink.

After a protein is made in the endoplasmic reticulum of an animal cell, it A) attaches to a ribosome on the ER membrane to be encoded and used in DNA replication B) is sent to the Golgi apparatus to be processed, stored, and sent to another destination C) is stored in the large central vacuole until it is needed by the cell for growth and repair D) travels to the mitochondria to be broken down and used for energy to power the cell
Answers
Answer:
B) is sent to the Golgi apparatus to be processed, stored, and sent to another destination
Explanation:
Proteins are important biomolecules produced in the cells of living organisms, specifically the Rough Endoplasmic reticulum (RER) attached to the ribosome (site of protein synthesis).
However, after production by the RER, the protein is sent to an organelle called the Golgi apparatus in order to be processed, stored, and sent to another destination by transport vesicles.
