Which adaptation would be most useful to an insect that lives in the grass?
long legs
green coloration
waterproof shell
strong wings
Answer:
Green Coloration
Explanation:
The adaptation that would be most useful to an insect that lives in the grass is green coloration. This would be a useful adaptation for them because now they could camouflage easily because the grass is green, and if they are also green and hiding in grass, nobody can spot them easily, which is a perfect way for them to hide from predators that may want to eat them.Organisms use camouflage to mask their location, identity, and movement. This allows prey to avoid predators, and for predators to sneak up on prey. ... The physical characteristics of the organism are important. Animals with fur rely on different camouflage tactics than those with feathers or scales, for instance.
Answer:
green coloration

A student placed 20 tobacco seeds of the same species on moist paper towels in each of two petri dishes. Dish A was wrapped completely in an opaque cover to exclude all
light. Dish B was not wrapped. The dishes were placed equidistant from a light source set to a cycle of 14 hours of light and 10 hours of dark. All other conditions were the same for both dishes. The dishes were examined after 7 days, and the opaque cover was permanently removed from dish A. Both dishes were returned to the light and examined again at 14 days. The following data were obtained:
Which of the following best supports the hypothesis that the difference in leaf color is genetically controlled?
a. the number of yellow-leaved seedlings in dish A on day 7
b. the number of germinated seeds in dish A on days 7 and 14
c. the death of all the yellow-leaved seedings
d. the existence of yellow-leaved seedlings as well as green-leaved ones on day 14 in dish B
Answer:
d. the existence of yellow-leaved seedlings as well as green-leaved ones on day 14 in dish B.
Explanation:
The observation is made with the tobacco seeds which are placed in two different dishes. The dished were placed in the light source for 14 hours. When dish B is observed there is yellow leaved seedlings which arises from the tobacco seeds.
How is efficiency related to systems?
Answer:
The efficiency indicates the manner in which the inputs are used by the system. Being efficient means the system uses inputs in a `right' way. If the input-output ratio is adverse, we say that the system is inefficient though it produces the desired output.

For the compound C₆H₁₂O₆, what type of bond would join the elements and why?
1. covalent because an electron is transferred from a C atom and O atom to a H atom.
2. covalent because electrons are shared between the C, H, and O atoms
3. ionic because an electron is transferred from a C atom and O atom to a H atom.
4. ionic because electrons are shared between the C, H, and O atoms
Answer:
4. Ionic bond because electrons are shared between the C,H and O atoms.
Explanation:
The atomic no. of carbon=6
Electronic configuration=2,4
The atomic no of H=1
E.C=1
The atomic no of O=8
E.C= 2,6
Therefore to attain octate state, they will share electrons
Answer:
4. Ionic bond because electrons are shared between the C,H and O atoms.

SOMEONE PLEASE HELP Which of the following examples is MOST likely to result in the formation of a new species? Select one:
A
A farmer applies a new fertilizer to her crops in order to encourage a much greater yield of corn.
B
An invasive species is introduced into the sea when an oil tanker releases the water it uses to float near a coral reef.
C
Many trees are knocked down when a new road is paved through a forest where many animal species live.
D
A fish population is divided when a long drought causes a lake to separate into two smaller bodies of water,
Answer: D
Explanation: The important thing to notice in this question is that it's asking for the FORMATION of a NEW species. That detail automatically removes B as the answer, because, while an invasive species could lead to a new species, it isn't likely, and there's the fact that B is talking about the INTRODUCTION of a species that already exists.
A could be correct, but fertilizer isn't likely to lead to a new species, as well as C, which would lead to a LOSS in species and biodiversity.
D is correct because it is an example of Allopatric Speciation, which is when one species converges into 2 species because of a physical barrier.

Plants are multicellular organisms in the kingdom Plantae that use photosynthesis to make their own food. They produce most of the world's oxygen, and are important in the food chain, as many organisms eat plants or eat organisms which eat plants. The study of plants is known as the botany.
