The Scarlet King Snake is a non-poisonous snake. It intentionally looks like the poisonous Eastern Coral Snake in order to scare away predators. What is this type of animal adaptation called?
A) camouflage
B) hibernation
C)migration
D) mimicry
Answer:
mimicry
Explanation:
Mimicry, in biology, phenomenon characterized by the superficial resemblance of two or more organisms that are not closely related taxonomically. This resemblance confers an advantage—such as protection from predation—upon one or both organisms by which the organisms deceive the animate agent of natural selection.
okay, the answer is D. mimicry. i mean- think about it: it cant be camouflage because like- camaflouge is where they hide like the stick bug. the stick bug camouflages into the tree. like- the stick bug has the same detail, looks like the tree. so it cant be camouflage. it cant be hibernation because snakes dont hibernate only fur animals do. snakes have scales. it cant be migration because only insects like butterflies, birds, and so on, only they migrate. snakes dont have wings. now we are left with D. if you think its A or D it can be but its D i got an A+ on my test with this question.

is competition abiotic or biotic?
Answer:
competition would be biotic if it were living or breathing
Explanation:
biotic means it lives, like plants or humans. abiotic means it doesnt live or breath, like a rock. i hope this helped
Competition is a biotic relationship that can have a substantial impact on populations of organisms.
What is meant by biotic? Biotic and abiotic factors are what make up ecosystems. Biotic factors are living things within an ecosystem; such as plants, animals, and bacteria, while abiotic are non-living components; such as water, soil and atmosphere. The way these components interact is critical in an ecosystem.Competition is a biotic relationship that can have a substantial impact on populations of organisms.

which of the following is not an example of mechanical weathering?
A. rocks being broken apart from freezing water
B. rocks being apart by plant roots
C. abrasion caused by wind blowing sand against rocks
D. dissolving of lime stone rock by ground water
Answer:
D
Explanation:
Because,
Mechanical weathering is the breaking down of rocks into smaller pieces without changing the composition of the minerals in the rock. This can be divided into four basic types – abrasion, pressure release, thermal expansion and contraction, and crystal growth.
The dissolving of limestone rock by groundwater is not an example of physical weathering.
Another name for mechanical weathering is called physical weathering. Some factors that aid or help in the mechanical weathering of rocks are:Wind, the thawing of frozen water found in rocks, e.t.c
Therefore, the dissolving of limestone rock by groundwater is not an example of physical weathering.
The correct option is option D

1.water for the mice to drink
2.rainy weather that floods the mice's nests
3.owls that prey on the mice
4.rocks in which the mice can hide from predators
Answer:
owls that prey on the mice
Explanation:
owls are the biotic or live factor that limits mice population because they hunt mice for food
Suppose a cool, damp autumn causes the cricket population to greatly increase. What will most likely happen to the frog and snake populations?
Answer:
also increase
Explanation:
more food more animals can eat causing animals to come and also breed then the crickets will go back down causing the predators to go back down giving them a chance to go back up and the cycle continues.
The plasma membrane is composed of both lipids and proteins. The relative concentration of each in the plasma membrane is partly regulated by the
Answer:
Golgi complex
Explanation:
The Golgi complex, also known as the Golgi apparatus, is a cell organelle of eukaryotic cells that functions to sort different molecules which are destined to the plasma membrane. In the Golgi apparatus, proteins and lipids from the Endoplasmic Reticulum (ER) are subsequently processed and classified to be transported to different cell locations including, among others, the plasma membrane, or vesicles which are secreted from cells by exocytosis. Moreover, this organelle also contains specific enzymes (glycosylation enzymes) that function to modify proteins in order to form glycoproteins.
The cholesterol synthesized by the cells used which component of the glycolytic pathway as a starting point
Answer:
This question lacks options, options are: A. glucose B. acetyl CoA C. pyruvate D. carbon dioxide. The correct answer is B.
Explanation:
Acetyl-CoA, the substrate for cholesterol synthesis is produced by the catabolism of carbohydrates, fatty acids and certain amino acids. Cholesterol comes from both diet and de novo synthesis from acetyl-CoA, biosynthesis that takes place preferentially in the liver; and to a lesser extent, in the intestine.Acetyl-CoA is converted to mevalonate, mevalonate is converted to squalene through successive reactions of transfer of prenyl groups. Squalene becomes lanosterol. Lanosterol is converted to cholesterol after 21 other successive, enzymatically catalyzed reactions.

Insects are a major danger to crop plants. Every year, insect damage destroys many plants that could be used to produce food. Genetic engineering can be used to insert a gene into crop plants that helps them resist insects. What is one potential risk of this use of biotechnology?
Answer:
1. Is it safe to consume a plant/crop that has been injected with genetic engineering?
Genetic engineering may have some risks as well such as production of genetically modified organisms interfere with the environment. The toxins produced by these organisms are found in other higher organisms.
What are the risks of genetic engineering?
Genetic engineering is also called as genetic modification. It is the modification of an organism's genes through the use of technology. It is a set of technologies which are used to change the genetic makeup of the cells, including the transfer of genes within and across the different species boundaries to produce new and improved or novel varieties of organisms. New DNA is obtained through either isolating and copying the genetic material of interest using recombinant DNA methods or through artificially synthesizing the DNA molecule.
Genetic engineering has some potential risks which include transfer of the selected gene into other species, this interferes with the nature, GM crops could be harmful for organisms, for example the toxins produced from these crops have been detected in the body of some organisms.

what is a company's obligation to contribute to the sustainability of natural resources?
Answer:
Under law? Depending where and what biz is there is NO obligation, or little if any in most cases.
Under morals, aka higher principles most bussinesses would just have to close.
Under Biblical principles, to subdue is one thing, to destroy is another. Much can be done but won't be because of cost/politics over logic. Sometimes that too is a natural resource, it's called freedom and or liberty and someone is using a lever for an alternate motive just saying it's for the 'trees’. Other cases it's plain and clear destruction for profit and nothing is said.
Record forest fires have occurred in west, some of it because environmentalists interfered with forest management to the point of cost in court and in the field leaving nothing to do. Areas that needed undergrowth and deadwood removed were kept untouched decades. Red tape and global warming made fuel stack up.
