Which question would be asked in a dichotomous key?
A. How long are the insect's antennae?
B. Are the insect's antennae longer than its head?
C. Are the insect's antennae long or short?
D. How does the insect use its antennae?
Answers
Answer:
B. Are the insect’s antennae longer than its head?
Explanation:
Dichotomous key refers to the tool or method which helps the scientist to identify organisms.
It uses a specific series of questions which help in segregation of organisms and ultimately help the scientist to identify the organism on the basis of the observations or properties share by the organism.
Example of a simple dichotomous key is shown below.
Similarly, insects can have antennae longer or shorter than their heads. Thus, the question "Are the insect’s antennae longer than its head?" would help in segregating insects based on their antennae length.
happy to help ya:)
The statement B is correct. Are the insect’s antennae longer than its head?
What do you mean by dichotomous keys?A dichotomous key is an important scientific tool, used to identify different organisms, based the organism's observable traits. Dichotomous keys consist of a series of statements with two choices in each step that will lead users to the correct identification.
Moreover, for example, in tree identification, a dichotomous key might ask whether the tree has leaves or needles. The key then directs the user down one list of questions if the tree has leaves, and a different question list if it has needles.
Therefore, dichotomous keys are useful for biological classification as well as identification. The word dichotomous is derived from the Greek words meaning “two parts.” Each step in the key provides two contrasting choices about a characteristic.

What structures (Homologous, Analogous, or Vestigial) would be most helpful in studying the selective pressures in an environment. Explain.
Answers
Answer:
Vestigial structure
Explanation:
Homologous structures are physical structures such as organs or skeletal elements present in numerous species that come from a shared common ancestor. Analogous structures are bodily structures that resemble one another superficially and provide a similar function but have evolved separately and do not come from a shared common ancestor (such as the wings of an insect and bat). One vestigial structure present in humans is the appendix. This organ was once vital in the consumption and digestion of uncooked meat, but no longer serves a function.
In the process of origin of species a lot of species has come from a common ancestor as homologous are the organism who have same structures and origin and same function as well while analogous are those who have same structures but functions are different in that case analogous and homologous are also considered as the organism from common ancestors but organism who have vestigial organs are not consider as the organism came from same ansector

If I drop a bowling ball and a golf ball from the same height, which has more potential energy? What about kinetic energy?
Answers
While the potential energy is the same for both objects initially, the bowling ball will have more kinetic energy than the golf ball as they fall.
An object's mass, height (or position), and velocity are what determine its potential energy and kinetic energy, respectively.
In this case, if you drop a golf ball and a bowling ball from the same height, their initial potential energies will be equal.
The height at which the objects are positioned and the gravitational pull on those objects both affect the potential energy.
Both objects' potential energy at the beginning is equal because they are dropped from the same height.
The objects' potential energy, however, is transformed into kinetic energy as they fall. The mass and speed of the items affect the kinetic energy.
The bowling ball will have more kinetic energy than the golf ball because of its greater mass.
Due to the fact that kinetic energy is related to the square of velocity, a bowling ball with a bigger mass will travel at a faster rate, producing more kinetic energy.
Thus, even though both items initially have equal potential energy, the bowling ball will have greater kinetic energy than the golf ball as they fall.

A class is learning about the evaporation step in the water cycle using a simple model. The model consists of a 1-L container of water. When the container is open, and it receives sunlight, the water can freely evaporate from the container. The students design an experiment using the model. In the experiment, the container will be filled and left open outside from dawn until dusk at different times of the year. The students will run the experiment only on days with clear weather. As a basis of their experiment, the students make an assumption that more water will evaporate from their model when more solar energy is present. Which of the following is a result that the students could predict in order to test their assumption?
A.
Equal amounts of the water will evaporate on summer days and winter days.
B.
Less of the water will remain in the container after one day in summer than after one day in winter.
C.
Less of the water will remain in the container after one day in winter than after one day in summer.

C) Auxins cause plants to grow wider.
D) Auxins cause plant cells to shrink on one side making it less heavy, which tips the plant on the other side.
Answers
Answer:A) Auxins make plant cells grow larger towards the light causing it to bend.
Answer:
A.
Auxins make plant cells grow larger towards the light causing it to bend.
Explanation:
The auxins go more in the shady side, and that is why there are more auxins in the shady side, but in the illuminated side, there are less auxins. That will cause a bend in the growth of the plant towards the light source because the shady side has more auxins to make it grow. This is the reason why when there are auxins in a plant, they start to grow towards light.

Why are coconut trees found in coastal areas?
Answers
The warm, humid climate near the ocean is ideal for coconuts, which require constant moisture. Coastal locations also provide easy access to water, whether from rainfall or seawater absorption through the roots, to keep the coconut palms hydrated. Sandy soil, abundant at the coast, allows the coconuts' extensive root systems to spread and helps retain moisture.
In addition, coconut palms are well-adapted to withstand salty winds and wind-borne salt spray from the ocean, bending but not breaking in strong storms. Their flexible trunks and fan-like leaves help them cope with windy conditions.
Coconuts near coastal areas provide ecological benefits as well. Their root systems stabilize beach soil and reduce coastal erosion. Coconut palms offer shelter and food for coastal wildlife like birds and crustaceans.
In summary, the combination of warm, moist air; access to water; suitable soil; and ability to endure coastal weather make seaside locations a coconut palm paradise where these trees can thrive.

If purple skin - P is dominant to red skin - p. What is the genotype for someone with red skin? *
Answers
Answer:
Every genotypic combination with DD or Dd is classified as Rh Positive (red).Explanation:
It may be because extra blood rushes to the skin's surface to fight off irritants and encourage healing. Your skin can also become red from exertion, such as after a heart-pounding exercise session.This is just an explanation of why there skin might turn red. Hope this helps!Answer: 50-60% chance of being a darker skin tone, in this case Purple (P).
And red skin would be: 40-50%
Explained:
The Genotype is the genes of an organism. A capital letter represents the dominant form of a gene ( P is a cap so it is dominant) , and a lowercase letter is the abbreviation for the recessive form of the gene (less dominant).
So darker skins have dominant traits. So
50-60% chance of being a darker skin tone, in this case Purple (P).
And red skin would be: 40-50%

Explanation:
Answer:
B. era
Explanation:
The word epoch means: a period of time in history.
We want to find a synonym for epoch, or a word that has the same meaning. So, if we were to replace epoch, the sentence would be the same.
Calendar: a chart showing the days, weeks and months of a year
Era: period of history that is long and distinct
Millennium: period of 1000 years
Timeline: a graphic representation of time passing
The word that makes the most sense as a synonym for epoch is era.
Therefore, the correct answer is B: era.

• also known as tropical grasslands
• few trees due to little rainfall
1)
(Savannas)
(Both Types of
Grasslands)
(Temperate
Grasslands)
Answers
Answer:
S - Savannas are typically found in tropical or subtropical regions.
S - Savannas tend to have more trees and shrubs.
S - Savanna's climate is drier than that of a grassland.
G - Grasslands are found in temperature regions.
G - Temperature Grasslands are mainly devoid of trees, receive less rainfall than Savannas & endure broader temperature extremes.
G - Grasslands make up 25 percent of the Earth's land surface and dominate in regions with limited rainfall, which prevents forest growth. This results from nearby mountain ranges that cause rain shadows over adjacent open-range lands.
B - Both represent the world's richest and most diverse ecosystems. They both provide a home for a quarter of the world's population and a habitat for thousands of plants and animals.
B - Many species gather in vast numbers, graze on the varied grasses, and can be found nowhere else on Earth. The coexistence between wildlife and grasses is key to healthy ecosystems. Animal migrations regenerate the landscapes, by controlling pests, dispersing seeds, and trampling invasive species. Through this partnership, grasslands and savannahs generate vital benefits for both people and nature.
B - Ecosystems such as these two in specific are essential for climate mitigation – they store carbon, locking it deep in the soil and extensive root systems. They are the source of or support many of the world’s biggest rivers and wetlands, ensure food security, support livelihoods, and are embedded in the cultural identity of millions of people.
(Also, A savanna or savannah is a mixed woodland-grassland<---similarity)
Explanation: Just research. I decided to state 3 characteristics for both The Savanna and The Grasslands, and then 3 for "B" (both).
