1.) What could happen if you remove an organism from a food chain?
2.) What is biodiversity?
3.) Why is biodiversity important in an ecosystem?
Answers
Answer:
1. every organism on the food chain will be affected. the ones below it will have a higher population, and the ones above it will have a lower population.
2. biodiversity is the idea, that all life is different, and environments thrive with it.
3. biodiversity is important in an ecosystem because if you take out biodiversity, you essentially take out all the animals in the given ecosystem.
Explanation:
1. when you remove lets say a spider from a food chain, the bugs that it would've eaten will start growing in population from not being eaten by the spiders. the birds that wouldve eaten the spiders, will decrease from the lack of that food source.
2. is self explanatory
3. if you only had one type of bird in one ecosystem, and that was the only animal in that ecosystem, the birds would all die, because they wouldn't have anything to eat, and nothing would eat it, so they might resort to cannibalism, or, as earlier stated, they would die off, from lack of food. the ecosystem would not be sustainable.

the normal flora of the skin is predominantly gram-negative rods. group of answer choices true false
Answers
The statement "the normal flora of the skin is predominantly gram-negative rods" is false because normal flora of the skin is predominantly gram-positive cocci.
Gram-negative bacteria are a group of bacteria that lack the essential thick layer of peptidoglycan that is present in the cell walls of Gram-positive bacteria. Gram-negative bacteria, which include the majority of clinically significant bacteria, are classified based on their cell wall characteristics, which contain an outer membrane with lipopolysaccharides (LPS) that can generate endotoxin under certain circumstances. Endotoxin is a potent mediator of sepsis in individuals and can also contribute to septic shock.
The normal flora of the skin is predominantly gram-positive cocci such as Staphylococcus and Streptococcus, as well as some gram-positive bacilli like Propionibacterium, and Actinomyces. Therefore, the given statement, "the normal flora of the skin is predominantly gram-negative rods" is false.

Read the article and use the information to answer the following question. Movement Explain how bones attach to each other and to muscles and how this aids movement.
Answers
The bones attach to each other and to muscles are done with the help of the Ligaments and Tendons- Connective Tissues.
There are two main connective tissues in our Musculoskeletal system which serve in joining the structures (bones and muscles) together and with each other.
Tendons provide the function of joining the muscles to the bone.Ligaments provide the function of joining the ends of the bones that make up joints.Both muscles and bones work together to help the body move. The word "origin" refers to the fixed end of a bone whereas "insertion" refers to the moveable end. As a muscle contracts, it applies pressure to the tendon, which then transmits that pressure to the bone, pulling it in the direction of the action. Ligaments both maintain the integrity of the bones and limit their range of motion.

In Black Angus cattle, the color black is what type of genetic trait?
recessive
incomplete
dominan
genotype
Answers
Answer:
dominant
Explanation:
The "gene" of an organism consists of two alleles. One allele comes from each parent. A genetic trait is said to be "dominant" even if there's only one copy of dominant allele present; however, a genetic trait is said to be "recessive" if there are two recessive alleles present.
In Black Angus cattle, the dominant color is "black." They are even named after their color. The recessive trait is "red." In order for a Black Angus cattle to be red, it needs to have two alleles for the recessive trait (red). However, it is easy for the cattle to be black as long as it has one allele for the dominant trait.
Define the terms hydrophilic and hydrophobic. What causes a molecule to be hydrophobic or hydrophilic?
Answers
Hydrophilic is a term used to describe something that interacts effectively with water, while hydrophobic is used to describe something that does not interact effectively with water.
A molecule that is polar and has a charge separation is hydrophilic because it is attracted to the polar water molecules.A molecule that is nonpolar and lacks a charge separation is hydrophobic since it repels water molecules. In general, hydrophilicity or hydrophobicity of molecules is determined by the chemical makeup of the molecule. In other words, whether a molecule is hydrophilic or hydrophobic is based on its polarity and the presence or absence of charged regions.
For instance, polar molecules such as water are hydrophilic and can interact effectively with other polar molecules. In contrast, nonpolar molecules such as oils are hydrophobic because they lack polar regions and are therefore not attracted to water. Thus, it can be said that the hydrophilicity or hydrophobicity of a molecule is mainly determined by the molecule's ability to either interact or repel water molecules.

A seahorse produces eggs in water, while a fern produces spores in the shade.
The eggs of a seahorse are spread by water, while the spores of a fern are spread by wind.
Answers
Whereas a fern generates a lot of spores, a seahorse produces an abundance of eggs. A fern produces many eggs, compared to the few that a seahorse produces.
Does a seahorse have milk production?Male seahorses will experience the same things a female does typically when she is pregnant. Prolactin, which is comparable to a hormone that causes pregnant mammals to create milk, is supplied to the eggs by the males.
What happens when a seahorse reproduces?One distinctive aspect of seahorses' reproductive behaviour is the fact that the male bears the fertilised eggs. During a lengthy courtship, the female deposits her eggs into the a brood pouch at the base of a male's tail, where they are later fertilised, using an ovipositor (egg duct).

These membranes form ____________ to transport these newly synthesized proteins and lipids to other parts of the cell.
Answers
The membranes that form the transport vesicles are responsible for transporting newly synthesized proteins and lipids to other parts of the cell.Transport vesicles are sac-like structures that are formed by the Golgi apparatus to transport molecules such as proteins and lipids to various locations within the cell.
Vesicles transport these molecules by fusing with other organelles. Vesicles are formed by budding from a donor membrane. Once the vesicle is formed, it may travel to another compartment or may fuse with another organelle to deliver its contents. So, ththe vesicles form to transport the newly synthesized proteins and lipids to other parts of the cell.
It is necessary to transport the newly synthesized proteins and lipids to other parts of the cell because it enables the cell to function properly.

Which reservoir is found underground in the cracks and spaces in the soil, sand, and rock?
A) Glaciers
B) Ground water
C) Polar ice caps
D) Rivers
Explain Why
Answers
Explanation: first of all, it is in the name. Ground water is water that is found in the ground. Another idea to find the answer would be to do process of elimination.
A glacier is a moving mass or river of ice that is mainly found in Antarctica and Greenland. Polar ice caps are regions that are covered in ice. A river is a natural flowing source of water that flows towards an ocean, sea, lake or another river. Ground water is water located beneath the Earth’s surface and can be found in cracks and rock formations. By doing process of elimination, you can easily cross out the possibility that the answer is glaciers or polar ice caps because they both have something to do with ice. This leaves you with rivers and ground water. You can eliminate rivers because rivers can’t fit into cracks and spaces in the soil. This leaves you with your answer of ground water.

Meal servings that are twice what a person can eat will be partially discarded. A perfectly edible apple with harmless spots or a misshapen carrot might be tossed in a landfill.
3)The world's food supply is abundant, not scarce. The world's production of grain and other foods is sufficient to provide at least 4.3 pounds of food per person, per day. The real reason for hunger in the world is poverty, which often strikes women--the nutritional gatekeepers in many families--the hardest. Economists argue that resolving hunger requires political solutions and not just agro-technical solutions.
