What posture is a dog displaying if she is leaning away from your, body lowered, ears back, tail down, showing whites of her eyes and the corners of her mouth pulled back.
Answer: Fearful and worried posture
Explanation:
Since dogs cannot talk, their body languages are used to interpret whatever emotion or feeling they may be experiencing.
When a dog is afraid, she tries to look small. She lowers her body and and leans away so that her center of gravity is over her hind legs to make a quick retreat easy. She also puts her tail down and ears flattened back to her skull. Her eyes also look rounder than normal and she shows the whites of her eyes (whale eyes).
All these tell that a dog is scared and worried or feeling tense.
Answer:
Defensive Threat Posture
Explanation:
Whale eye (whites of eyes showing)
Tail down or fully tucked
Piloerection
Ears back or flatten against head
Pupils dilated
Corners of mouth pulled back
Body lowered
Body leaning backward
A defensive threat posture indicates a dog is being self-protective. This is seen in a dog who is fearful and would prefer to run away from the situation, but may bite if provoked or cornered. Stress signals were offered in the beginning, however ignored and the dog is showing extreme fear.

4. Genes that are responsible for new characteristics that help a species survive in a particular environment
are most likely to do which of the following?
A. rapidly decrease in frequency
B. gradually decrease in frequency
C. increase in frequency
D. not change in frequency
Answer:
The correct answer is - increase in frequency.
Explanation:
According to the theory of Darwin, organisms most likely survive and reproduce in an ecosystem that is able to change or adapt to the changes in the ecosystem.
According to the modern evolutionary theory that the genes that are responsible for new changes or traits that help a species to reproduce and survive in a particular environment increase in frequency and the genes do not helps decrease in frequency.
If no energy is transferred, how much work is done?
Answer:
Explanation:The potential energy is converted to kinetic energy in the process. But I see no transfer of energy between the earth and the body.
And how does energy transfer takes place in case of negative work ? When a body is moved across a surface which has friction, the friction does negative work. Does it mean that a sort of energy transfer occurs between the surface (source) and the body (object
Lactase is an enzyme that many different animals have that helps digest the sugar lactose Why can this enzyme be the same in different species?
0 Lactase is necessary for survival of all organisms
0 All living things share a common code-DNA
0 Lactase is not regulated by external environments.
It is not possible for it to be the same in different species
Answer:
All living things share a common code-DNA
Explanation:
Enzymes are proteinous substances, which like every other proteins are encoded by a genes. In the expression of these genes, a set of codons (three nucleotide base) called GENETIC CODE is used. ONE of the characteristics of this genetic code is that it is NEARLY UNIVERSAL meaning that the same genetic code is used by virtually all known living organism.
According to this question, lactase enzyme, which helps digest lactose sugar in organisms, is the same in different organisms. This is due to the fact that all living things share a common code-DNA e.g AUG codes for methionine in all organisms, hence, when these DNA undergoes expression, it yields the same products in different organisms.

Identify the 2 constructive processes from the list below.
A) A river wears away the land creating a canyon.
B) Over time a mountains top becomes less jagged and more rounded.
C) A volcano erupts and lava flows down its sides.
D) Silt is deposited at the mouth of a river.
Answer:
C, D.
Explanation:
C: The flowing lava creates extra rock. For example, entire islands are formed via this process of volcanos erupting, lava cooling, repeat.
D: Silt from erosion (erosion itself is considered destructive, but the resulting silt can turn into something constructive.) can build up entire mounds or mountains over time.
Which structure inside plant cells helps in photosynthesis?
Chloroplast
Mitochondrion
Nucleus
Vacuole
Answer:
chloroplasts
Explanation:
chloroplasts
Photosynthesis takes place in chloroplasts; cell walls allow plants to have strong, upright structures; and vacuoles help regulate how cells handle water and storage of other molecules.
Answer:
Chloroplast
Explanation:
photosynthesis takes place in chloroplasts
What makes hunting breeds a good choice for studying dog navigation?
Answer: Pointers make an excellent choice for these excursions because they are lean and biddable—important qualities in dogs who will be hundreds of yards away from you during long-range hunts. Conversely, a dog plying the thick woods of a ruffed grouse covert will need to work close.
Explanation:
hunting breeds, such as dachshunds, foxterriers, and Welsh terriers. For generations, people have bred hunting dogs to track prey andthen find their way back to their owners. “Weknow about homing behaviors in these breedsfrom observations, but they haven’t been studiedin detail,” says Benediktová.

Create a sentence explaining how amino acids
form proteins.
Answer:
Proteins are the final products of the sequencing process that begins with cellular DNA information.
Explanation:
Proteins form structural and motor components in the cell as workhorses of the cell, and they serve as the catalysts for virtually every biochemical reaction in living things. This incredible array of features stems from a remarkably simple code that defines a greatly varied collection of structures.

True or false: Guard cells close openings in the leaves slowing down water loss.
Answer:
True
Guard cells close openings in the leaves slowing down water loss.
Answer:
True
Explanation:
Stomata are pores in the leaf that allow gas exchange where water vapor leaves the plant and carbon dioxide enters. Special cells called guard cells control each pore's opening or closing. When stomata are open, transpiration rates increase; when they are closed, transpiration rates decrease. So when it is opened the water vapor depletes quicker but when its closed it slows down the process of depletion.
