Answer: When organisms use organic matter for cellular respiration, ALL the goes back into carbon dioxide, water, and minerals, while ALL the energy leaves the ecosystem as heat. So matter cycles, energy flows through ecosystems. So It is C
Explanation: A. The producers generate food for themselves and others; consumers do not produce anything, instead eating producers, other consumers or both.
B. Autotrophs make food for their own use, but they make enough to support other life as well.Heterotrophs cannot make their own food, so they must eat or absorb it.
So C is correct
Matter and energy always flow from the in ecosystems from autotrophs to the consumer.
What is ecosystem?The energy flow in the ecosystem is one of the important factors that enables the survival of such a huge number of animals. An ecosystem is made up of a network of connections between living and non-living elements.
All of the energy needed by living things is provided by the sun. About 1% of all radiant energy is absorbed by green plants and distributed throughout the ecosystem.
According to the first law of thermodynamics, energy cannot be generated or destroyed. The energy source, in this case solar energy, cannot be created or destroyed. It can only be moved from one system to another, just like a form is moved from one form to another.
Therefore, Matter and energy always flow from the in ecosystems from autotrophs to the consumer.

Which of the following is false regarding the protein pepsin?
A. Pepsin hydrolyzes peptide bonds.
B. Pepsin is a type of protease.
C. Pepsinogen is the active form of pepsin.
D. Pepsinogen self-cleaves at the pH found in the stomach.
E. None of the above are false.
Answer:
C. Pepsinogen is the active form of pepsin.
Explanation:
Pepsin is a gastric protease belonging to the aspartic proteinase family which breaks down polypeptide chains into smaller peptides by hydrolyzing peptide bonds. Pepsin is found in the gastric juice where it digests proteins from foods together with other digestive enzymes and hydrochloric acid. Moreover, pepsinogen is a precursor of pepsin which is secreted by the gastric chief cells of the human stomach and then is converted into pepsin (its active form) by hydrochloric acid.

Explanation:
A peony plant with straight stamens and red petals was crossed with another plant having straight stamens and streaky petals. The seeds were collected and germinated and the following offspring were obtained 62 straight stamens with red petals 59 straight stamens, streaky petals 18 incurved stamens, red petals 22 incurved stamens, streaky petals a) Which alleles in each pair are dominant
Answer:
Explanation:
From the given information.
Let the Straight stamens be S;
The incurved stamens be s;
The red petals be R; and
The streaky petals be r
The genotype of the parental plants are Straight stamens, red petals (SsRr) and Straight stamens, streaky petals)
So if SsRr and Ssrr crossed together, Then we have the following:
If SsRr self crossed, we have the following traits = SR Sr sR sr; &
Ssrr = Sr Sr sr sr
Then, the dihybrid cross is:
SR Sr sR sr
Sr SSRr SSrr SsRr Ssrr
Sr SSRr SSrr SsRr Ssrr
sr SsRr Ssrr ssRr ssrr
sr SsRr Ssrr ssRr ssrr
P(Straight stamens, red petals) = 8/16
P(Straight stamens, streaky petals) = 6/16
P(Incurved stamens, red petals ) = 2/16
P(Incurved stamens, streaky stamens) = 2/16
When viewing the shape of a human cheek cell, what microscope would most likely be used?
A.) Light
B.) Dissecting
C.) Transmission Electron
D.) Scanning Electron
Answer:
Your answer Is C!!!!! :)))
Explanation:
A light microscope can be used to view the shape of a human cheek cell. So the correct option is A.
What is a light microscope?In many research labs, including those using electron microscopes, light microscopes are crucial tools. They can be used to support electron microscopy or as the main viewing tool. The methods used to prepare samples for light microscopy are constantly expanding, and they might include everything from tissue cultures and sliced biological creatures to samples from the sciences of materials and geology.
There are significant parallels between the optical principles of light and electron microscopes. Understanding the operation of a light microscope is essential for both getting the best possible light pictures and comprehending electron microscopy.
We make use of the waveform characteristics of light in microscopy. When generated at a specific source, these waves vibrate perpendicular to the direction of transmission. There are peaks and troughs on every wave. One wavelength is the length of the light ray's onward journey (lambda). The color and intensity of the source affect the wavelength.
Therefore the correct option is A.

In an experiment, Dr.Travis examined the effects of calcium intake on osteoporosis, a condition that causes an increased risk of bone fractures. The amount of calcium ____ variable. The risk of bone fractures _________.
1. A reliable
An independent
A dependent
2. Can be changed by the participants
Can be changed by the researcher
Could change with calcium intake
Answer:
Part 1. The amount of calcium is independent variable.
Explanation:
An independent variable is a variable in an experiment which is changed to see its effects on dependent variable.
In this experiment, to know about the causes of osteoporosis, the Ca level in blood or calcium intake in changed.
So the concentration of calcium will be independent variable.
Part 2.
The risk of bone fractures is could be changed with calcium.
Explanation:
In this experiment osteoporosis or risk of bone fracture is dependent variable.
Dependent variable are results of experiment which can be changed by independent variable.
As in experiment, Calcium concentration is independent variable.
So the risk of osteoporosis depends can change with calcium.
