Answer:
Abiotic factors.
Explanation:
Abiotic factors such as temperature and humidity etc challenge the stability of an organism by providing the harsh environment. This harsh environment disturbs the stability of the organism. Increase in temperature and very less or high humidity imbalance the enzyme activity which disturbs the whole functioning of the body of organism. So for chemical processes in the body, suitable temperature is required.

why are lions smaller than elephants
Answer: Lions are smaller so they can get their pray with out being seen.
Explanation: Elephants are large, and because of this they are slow. So, if a lion was as big as a lion, their pray would see them and they could not catch it and they would go hungry.

c) In dense rainforest, plants that grow close to the forest floor tend to have lower rates of photosynthesis than the very tall trees. Suggest why this might be.
Answer:
The reason why plants that grow close to the forest floor tend to have lower rates of photosynthesis is because sunlight is a vital component in the production of glucose. Using logic, you can see that the tree cause larger shadows to form—blocking sunlight.

Please Help! Which terms describe the periwinkle snails? Select all that aply more than one answer!
a. herbivores
b. heterotrophs
c. secondary autotrophis
d. members of the second trophic level
e. carnivores
f. primary consumers
Answer:
a, b, d, and f.
Explanation:
The periwinkle snails feed on plants. Consequently, they are said to herbivorous and heterotrophic since they cannot manufacture their own foods. They are also referred to as primary consumers because they directly feed on plants without any other nutritional option. They, therefore, occupy the second trophic level on a typical food web.
The correct options are a, b, d, and f.
Select all Options that are enzymes.
1. Sucrose
2. Lipase
3. Glycerol
4. Trypsin
5. Pepsin
6. Deoxyribose
all of the above are different kinds of enzymes
a valid hypothesis must be testable true or false?
Answer:
I think it is false.
The percentage of energy in one trophic level that transfers to the next level in the average ecosystem is 10 percent. Trophic levels are the feeding positions of all organisms that are located in a certain ecosystem. Trophic levels describe what different organisms consume. As energy is transferred from one trophic level to another in an ecosystem, it decreases. Only a small amount of the energy (as little as 10 percent) at any trophic level is moved to the next trophic level. The remaining energy is lost mainly as heat through metabolic processes.
Answer:
See explanation
Explanation:
According to the second law of thermodynamics, energy transfer from one trophic level to another is not 100% efficient. Some energy is lost along the way from one trophic level to another.
The reason for this loss in energy is that the organisms at each trophic level harnesses the energy that they derive from complex organic matter to carry out their own metabolic processes.
Hence, only about 10% of the energy originally derived from complex food materials is passed on to the next trophic level.
Summarily, only about 10 percent of energy derived from food and stored in biomass in a particular trophic level is passed from one level to the next. This is commonly referred to as “the 10 percent rule”. This rule limits the number of trophic levels that can be supported by a given ecosystem.
Answer:
10 percent

Select the Two characteristics that these proteins have in common.
A( They contain nitrogen
B( They are made of disaccharides.
C. They are Composed of amino acids.
D( They form by using fatty acids and glycerin.
E( They Contain a base, sugar and a phosphate group.
Answer:
C, D
Explanation:
The common property of all proteins is that they consist of long chains of α-amino (alpha amino) acids. The general structure of α-amino acids is shown in . The α-amino acids are so called because the α-carbon atom in the molecule carries an amino group (―NH2); the α-carbon atom also carries a carboxyl group (―COOH).
If carrot sticks are put into water and refrigerated, they become turgid and stiff, but if red blood cells are given the same treatment, they burst or lyse. Explain the difference in the results.
Answer:
Because carrot isn’t the same matter as a red blood cell so if a blood cell gets cold it bursts
Explanation:
They have different chemical compounds
The carrot cells become turgid whereas red blood cells burst or lyse in the given condition due to plant cells have two organelle that prevents it from lysing which are, the cell wall and a large vacuole.
Plant cells have a cell wall around their cell membrane and have a single large vacuole whereas in animals the cell wall is absent and found small vacuoles.
When water moves into a plant (carrot) cell, the vacuole becomes bigger. it causes pressure on the cell wall and increases the turgor pressure within the cell making it stiff. The pressure occurred by the cell wall prevents too much water to enter and prevent cell lysis.It lacks in the animal cells that results in cell lysis due to too much water enters in it.Thus, the difference, in this case, is due to plant cells have two organelle that prevents it from lysing which are, the cell wall and a large vacuole.

what are the differences between sexual and asexual reproduction?
Answer:
Explanation:
DIFFERENCES
SEXUAL REPRODUCTION Sexual Reproduction is a type of reproduction in which one or two organisms or individuals are involved. Fusion of gametes occurs and the offspring’s have different characters. There are sexual organs for both male and female and the organs of both male and female come into contact at the time of reproduction.
ASEXUAL REPRODUCTION Asexual Reproduction is a type of reproduction in which only one organism is involved. There will be no fusion of gametes and The offspring will exactly resemble the parent. There are various kinds of asexual reproduction and some of them are binary fission, budding, fragmentation, parthenogenesis, sports, etc.
Explanation:
asexual
without sexual feelings or associations.
Sexual
acctual feelings or associations.

Organisms become extinct for many reasons. All BUT one is reason for extinction. That is
A) adaptations.
B) over-hunting.
C) climate change.
D) habitat destruction.
Answer:
A) Adaptations
Explanation:
If a species learns to adapt to their environment, then they will not become extinct
Answer:
adaptation
Explanation:
When a organism adapts to its surroundings it docent become extinct instead it survives. It wouldn't make sense that if it were to adapt then it would be extinct. While over hunting is a cause of extinction and so is climate change if the organism is not well adjusted to any temperature. Habitat destruction is also a cause of extinction because it kills the organisms home causing them to not have anywhere to live. So adaptation is the correct answer.
