When a phase change (like liquid to gas) occurs, it normally begins at a location that ... a slight disturbance (like putting in a spoon or some sugar, or moving it ..
Explanation:
Answer:
Since the water is boiling, and a lid is on there is a major amount of thermal energy just waiting to go somewhere, not to mention it takes the form of steam which much escape somehow, likely causing a very faint movement on the top of the kettle.

Which of these might be part of an animal’s circulatory system?
Answer:
heart, blood vessels, blood
Explanation:
Heart, blood vessels and blood might be part of an animal's circulatory system.
What are the functions of circulatory system?The blood circulatory system is a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the entire body of a human or other vertebrate.
The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide. These roadways travel in one direction only, to keep things going where they should.
The circulatory system consists of three independent systems that work together: the heart (cardiovascular), lungs (pulmonary), and arteries, veins, coronary and portal vessels (systemic).

Which is not a major difference in the organization or content of prokaryotic and eukaryotic genomes?
a) Prokaryotic genomes generally have less DNA and fewer genes than eukaryotic genomes.
b) Prokaryotic genomes have fewer repeated sequences and noncoding, intragenic sequences than eukaryotic genomes.
c) Most prokaryotic genomes are contained in one chromosome; most eukaryotic genomes are contained on several.
d) In general, eukaryotic genomes contain many introns, repeated sequences, and transposable elements. of the above are true
Answer:
All of the above are true
Explanation:
Organisms possess two types of genome viz; prokaryotic genome and eukaryotic genome. The eukaryotic genome is possessed by cells with a well-defined nucleus, where their genetic material (DNA). The prokaryotic genome, on the other hand, lacks a membrane-bound nucleus. The major organization or content between these two genomes are:
- Prokaryotic genomes generally have less DNA and fewer genes than eukaryotic genomes.
- Prokaryotic genomes have fewer repeated sequences and noncoding, intragenic sequences than eukaryotic genomes.
- Most prokaryotic genomes are contained in one circular chromosome while most eukaryotic genomes are contained on several linear chromosomes.
- In general, eukaryotic genomes contain many introns, repeated sequences, and transposable elements.

Which of the following are contributions of deforestation to global climate change? Select all that apply.
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.
Clearing of forests increases the leaching of nutrients in affected regions.
Deforestation increases the risk of landslides in cleared regions.
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)
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 ;)

What is the purpose for cleaning and sanitizing prep utensils and
surfaces between tasks?
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.

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?
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.

ATP and photovoltaic cells are similar because they both produce chemical and electrical energy.
ATP- A vital "energy molecule" present in all living things is adenosine 5′-triphosphate, also known as ATP and typically written without the 5′-. In particular, it's a coenzyme that transfers energy to cells by generating its phosphate groups when it interacts with enzymes like ATP triphosphatase. ATP is generated when the particular wavelength of the light fall on the chlorophyll which converts the light energy into chemical energy.
Photovoltaic Cells- Photovoltaic systems (PV) cells use the light energy from the sun to create a electrical current by absorbing the light energy. A single solar cell has several PV cells, and the total current produced by all of these cells when combined is sufficient to power the various destinations.

Which type of cell is found in the hypodermis?
Answer:
The hypodermis contains the cells known as fibroblasts, adipose tissue (fat cells), connective tissue, larger nerves and blood vessels, and macrophages, cells which are part of the immune system and help keep your body free of intruders.
Explanation:
The hypodermis is made up of fibroblasts, these cells are a part of the body's connective tissues. These secrete collagen proteins that help in maintaining the structural framework of body.
What is Hypodermis?
The hypodermis is the bottom layer of the skin in the body. It performs many important functions such as storage of energy, connecting the dermis layer (upper layer) of the skin to the muscles and bones underneath, insulating the body during different temperature range and protecting the body from harm which could happen due to injury. As a person age, the hypodermis decreases in size, and the skin starts to sag and becomes more vulnerable to harm and injury.
