The table below shows salinity tests from coastal Louisiana following a salt water influx during hurricanes Katrina and Rita. If efforts are not made to reduce the salinity in these areas, what is the most likely long term effect?
A growth in the population of salt-intolerant types of plants
A shift in species composition to less salt-tolerant plants
A shift in species composition to more salt-tolerant plants
An increase in the diversity of salt-intolerant plants
Answers
A shift in species composition to less salt-tolerant plants is the most likely long term effect.
What are the characteristics of salt-tolerant plants?The salt tolerance test is performed using Tryptic Soy Broth with added sodium chloride (regular table salt) to create an overall salt concentration of 6.5%. It is a selective medium which tests the ability of an organism to survive in a salt-rich environment.
The salt tolerance of a plant is often defined as the degree to which the plant can withstand, without significant adverse effects, moderate or high concentrations of salt in water on its leaves or in the soil within reach of its roots.
Hypersensitivity to catecholamines may be the cause of salt sensitivity. A low sodium concentration in saliva deserves further study as a simple screening test to identify salt-sensitive subjects.

What are the characteristics of autotrophs?An autotroph or primary producer is an organism that produces complex organic compounds using carbon from simple substances such as carbon dioxide, generally using energy from light or inorganic chemical reactions.
Plants are the most familiar type of autotroph, but there are many different kinds of autotrophic organisms. Algae, which live in water and whose larger forms are known as seaweed, is autotrophic.
Examples of organisms that are autotrophic are plants and algae, and they have specialized cell organelles that have the ability to power the process of photosynthesis.

Two parrots have different parents. One parrot has red chest feathers, and the other parrot has yellow chest feathers. Why do the parrots have different feather colors on their chest?
Answers
Answer:
Hereditary traits.
Explanation:
Since these two parrots (with two different parents), one with yellow feathers and the other one red, it would make sense that they inherited their traits from their parents.
Just as humans have different colors of hair. Parrots can have different chest colors. Both of these come from hereditary genes.

What is the purpose for cleaning and sanitizing prep utensils and
surfaces between tasks?
Answers
Answer: When you clean and sanitize, it prevents the potential spread of germs and disease
The purpose of cleaning and sanitizing food contact surfaces is to remove the nutrients that bacteria need to grow, and to kill the bacteria that are present. Clean, disinfected equipment is important and should be kept dry to prevent bacterial growth.
What is Cleaning and Sanitizing?Disinfection is defined as the actions that do not necessarily clean dirty surfaces or remove germs. Sanitation can be done by cleaning, disinfection, or both. Cleanliness means that we are reducing the number of germs to a safe level.
Cleaning means removing food and other types of soil from a surface such as a countertop or plate while sanitization reduces the number of pathogens on that cleaned surface to a safe level.
Cleaning with detergent or soap and water removes dirt and grime from surfaces such as floors, walls, carpets, windows. Sanitizing removes dirt and small amounts of germs where certain objects and surfaces are cleaned to remove dirt then sanitized such as bathrooms, counters, toys, utensils, silverware
Thus, the purpose of cleaning and sanitizing food contact surfaces is to remove the nutrients that bacteria need to grow, and to kill the bacteria that are present. Clean, disinfected equipment is important and should be kept dry to prevent bacterial growth.

Cut trees are often burned, and this releases carbon into the atmosphere.
Clearing of forests increases the leaching of nutrients in affected regions.
Deforestation increases the risk of landslides in cleared regions.
Answers
Answer:
The correct answer is -
Conversion of forest to cropland or pasture decreases the rate at which carbon is taken up by plants.
Cut trees are often burned, and this releases carbon into the atmosphere.
Explanation:
Deforestation is the manual removal of the forest and trees permanently to make the land available for places other than forests such as agricultural land, road or cities, and industries. There are many negative impacts of deforestation on the environment and ecology such as reduces biodiversity , soil erosion , a higher chance of flooding , educes soil fertility , global warming, and many more.
Global warming can be influenced by deforestation as if the forests are removed to create cropland the uptake of carbon dioxide will be very less in comparison to the forests as trees use carbon uptake at a higher rate. Many times deforestation also results in burning the trees and log of trees which contribute to the release of more carbon dioxide in the atmosphere. So deforestation means more CO2 in the atmosphere which leads to global warming.
How is it possible that organisms with the same phenotype can have different genotypes?
a Different physical traits (genotypes) can lead to the same genetic makeup (phenotype)
b Different physical traits (phenotypes) can lead to the same genetic makeup (genotype)
c Different genetic makeups (phenotypes) can lead to the same physical traits (genotype)
d Different genetic makeups (genotypes) can lead to the same physical traits (phenotype)
Answers
Answer:
I think it is C (Different genetic makeups can lead to the same traits.)
Explanation:
An organism's genotype is the combination of alleles found at a particular gene. The phenotype is how theses alleles are expressed to form a trait.
In a diploid organism there are two alleles for every gene. In simple Mendelian traits. one allele is dominant over the other, which is recessive. That means, that the phenotype displayed will be associated with the dominant allele whenever it is present.
phetotypes is physical looks. people look similar but have different genotypes you get what im saying, because one genotype gets masked over the other. like blond and black come together black will win but blond is still in genes so thats how this would work ;)

Meiosis reduces chromosome number and rearranges genetic information. Explain how reduction and rearrangement are accomplished in meiosis. Include at least 3 ways this happens.
Answers
Answer:
Following are the solution to the given question:
Explanation:
Reduction: Throughout Meiosis I, in mitosis, two pairs pair and separate and transfer towards opposites throughout prometaphase I. Before Metaphase ii they separate the chromosomes during Metaphase II. There's also no gene replication between meiotic division I and meiosis II, and the resultant genomes have lower genetic data (chromatids) than parent organisms.
Through meiosis, genomes are formed in homologous pairs, in mitosis I and II. The spontaneous arrangement of helices with both the plate is the dependent result. During prometaphase I and II, the genomes divide so each gamete earns one of every chromos form. In Interphase I, tetrad interaction occurs throughout chiasma, contributing to genetic diversity.
What characteristics define bacteria?

There are three notable common traits of bacteria, 1) lack of membrane-bound organelles, 2) unicellular and 3) small (usually microscopic) size. Not all prokaryotes are bacteria, some are archaea, which although they share common physicals features to bacteria, are ancestrally different from bacteria.Answer:
Bacteria are like eukaryotic cells in that they have cytoplasm, ribosomes, and a plasma membrane. Features that distinguish a bacterial cell from a eukaryotic cell include the circular DNA of the nucleoid, the lack of membrane-bound organelles, the cell wall of peptidoglycan, and flagella.
