Answer:
The desirable bacteria cause less deterioration of the food by inhibiting the growth of the spoiling types o bacteria. Some fermenting processes lower the pH of foods preventing harmful microorganisms to live with too acidic an environment. Controlled fermentation processes encourage the growth of good bacteria which starves, or fights off, the bad microbes. Depending on what is fermented, or the manner of fermentation, foods can remain consumable for years!!

Consider the following statements:
1. Mutations always have a negative effect on an individual.
II. Mutations can have a positive effect on an individual.
III. Murations can have no effect on an individual.
IV. Mutations can have a negative effect on an individual.
Which of the statements above is/are true?
Answer: II, III, and IV
Explanation:
The answer is the second, third, and fourth.
The second one is true, because some mutations can help us adapt to our surroundings.
The third one is true, because some mutations such as some point mutations won't affect the proteins that are synthesized.
The fifth one is true, because some mutations are lethal.
which trait is not a genetic trait
Answer:
long hair
Explanation:
Answer:
Long Hair
Explanation:
Three species of finches are in competition for the limited resources of an ecosystem. One species
prefers fruit to seeds. The second species prefers seeds to fruit. The third species will eat fruit or
seeds with equal preference. If the third species is removed from the area, how will the ecosystem
change?
a. Resources will be more abundant.
b. The climate of the ecosystem will change.
c. Fruit and seed resources will become less abundant.
d. Water will become more readily available.
Answer:
the answer is option a
Explanation:
The finches evolved to have different beak shapes to be able to eat the food available on the different islands.
If one species is removed then the resources will be more abundant for the other two species.
What will happen if 3rd species is removed?If the third species is removed from the area then seeds and fruits will be more available for the one and second species.
Because the third species is eating both seeds and fruits in equal preference if they are removed then these resources will be available in more abundant for the other two species.
Thus, we can conclude that the correct option is (a), Resources will be more abundant.

What is photosynthesis
Answer:
The process of a plant converting sunlight, carbon dioxide and water into food
Explanation:
Hey there!
Photosynthesis is the reaction that converts light energy to chemical energy in sugar and carbohydrates. Humans can't eat sunlight, so we eat plants. Plants convert the energy in the sunlight into chemical energy using chlorophyll. Chlorophyll is a molecule produced by plants, algae, and cyanobacteria, which aids in the conversion of light energy into chemical bonds. It is the green pigment found in the chloroplasts of higher plants. They are a part of our ecosystem, and they are lower on the food chain.

using Punnett Squares, determine the percentage of offspring which would be heterozygous from the following cross: BB x bb
A. 25%
B. 50%
C. 100%
Lets take that the father has black hair and the mother has brown hair so -->
Male × Female
Genotypes: BB × bb
Phenotypes: Black brown
Gametes: B _100%_ b_100%_
After reviewing the photo
we have
Genotypes
B: 50% (1/2)
b: 50% (1/2)
Phenotypes
Black: 50% (1/2)
brown: 50% (1/2)
Using Punnett Squares, the percentage of offspring would be heterozygous from the following cross: BB x bb is 25%. Therefore, option (A) is correct.
What are the features of punnett square method?The Punnett square is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment. It is named after Reginald C. Punnett, who devised the approach in 1905.
The Punnett square is a table in which all of the possible outcomes for a genetic cross between two individuals with known genotypes are given. In its simplest form, the Punnett square consists of a square divided into four quadrants.
A Punnett Square is a helpful tool that helps to predict the variations and probabilities that can come from cross breeding. This includes predicting crossing plants, animals, even humans with each other.

What type of species is most likely to lead to extinction of another species? a Invasive species b Native species c Genetically isolated species d A and B
Answer:
A
Explanation:
Like Christopher Columbus
:)
The type of species that is most likely to lead to the extinction of another species is known as Invasive species. Thus, the correct option for this question is A.
What is Species?Species may be defined as a cluster of organisms that can reproduce with one another in nature and produce fertile offspring.
Invasive species are those that are not native to a particular habitat. They just arrive there in search of resources that support them in order to survive and reproduce naturally.
These arrived species utilize the resources like food, space, etc. of the native species and make them oppressed to eliminate from this habitat.
Therefore, invasive species is the type of species that is most likely to lead to the extinction of another species. Thus, the correct option for this question is A.

The respiratory system interacts with the environment by contracting and expanding the diaphragm and chest in order to do breathing. When the muscles in the diaphragm contracts and the expansion of chest occurs, takes the air inside the body that is present in the outside environment for inhalation of oxygen while on the other hand, when the diaphragm expands and chest contract, the air inside the body is removed with the removal of carbondioxide gas.

Allosteric enzymes are enzymes that posses the presence of an additional site and an active site. they are modified by a noncovalent binding an allosteric effector. They do not posses a kmvalue hence they do not obey Michaels-Menten kinetics
Explain why a leaf kept in the light for 24 hours will turn an iodine solution blue-black, whereas a leaf kept in light for 24 hours and then in the dark for 24 hours will have no effect on an iodine solution
Answer:
The leaf kept in the light will turn blue-black because of the presence of starch after photosynthesizing. The leaf in the dark could not photosynthesize, which would not create starch so the iodine solution will have no effect.
Explanation:
Iodine stains a blue black in the presence of starch
