Answer:
A shared character is one that two lineages have in common, and a derived character is one that evolved in the lineage leading up to a clade and that sets members of that clade apart from other individuals.
Answer:
A shared character is one that two lineages have in common, and a derived character is one that evolved in the lineage leading up to a clade and that sets members of that clade apart from other individuals. Shared derived characters can be used to group organisms into clades. For example, amphibians, turtles, lizards, snakes, crocodiles, birds and mammals all have, or historically had, four limbs. If you look at a modern snake you might not see obvious limbs, but fossils show that ancient snakes did have limbs, and some modern snakes actually do retain rudimentary limbs. Four limbs is a shared derived character inherited from a common ancestor that helps set apart this particular clade of vertebrates.

Which is the best reason that a geologist might carry a small dropper bottle filled with hydrochloric acid
when doing fieldwork?
to wash rock samples to make them easier to study
to wear away large areas of rock to see what is underneath
to test for the presence of carbonate minerals in a rock
to use as an emergency eyewash in case rock dust gets in the eyes
Answer:
C, to test for the presence of carbonate minerals in a rock
Explanation:
I did this a few weeks ago on Edge. Hydrochloric acid isn't for rock washing, they wouldn't use it to wear away rocks since it'd ruin the sample I think, and you will go blind if you put it in your eyes
Geologist carry dropper bottle filled with hydrochloric acid when doing fieldwork is to test for the presence of carbonate minerals in a rock.
Test for carbonate mineralsHydrochloric acid is used to test for presence of carbon iv oxide in compounds.
When hydrochloric acid reacts with carbonates, it produces effervescent due to the prensence of carbon iv oxides in the compound.
Geologist will use this acid (hydrochloric acid) to check if the rock sample contains carbonate minerals.
Thus, the best reason that a geologist might carry a small dropper bottle filled with hydrochloric acid when doing fieldwork is to test for the presence of carbonate minerals in a rock.

Suzy knows that an individual’s sex is determined by sex chromosomes. She knows that females have two X chromosomes and males have one X and one Y chromosome. She creates the Punnett square cross below to show sex inheritance. She wants to know which parent determines the sex of a baby---is it the mother, father, or both? Complete this cross. What would you tell Suzy? Why? Suzy knows that an individual’s sex is determined by sex chromosomes. She knows that females have two X chromosomes and males have one X and one Y chromosome. She creates the Punnett square cross below to show sex inheritance. She wants to know which parent determines the sex of a baby---is it the mother, father, or both? Complete this cross. What would you tell Suzy? Why?
She creates the Punnett square cross below to show sex inheritance. She come to know that both parent determines the sex of a baby and it is when you put xx and xy on a punnet square there are equal amounts male and female.
How Human sex gets decided?Human sex gets decided by the function of SRY gene which possessed by with or without of Y chromosome. The hormone of anti-mullerian and testosterone produced from cells when activating the SRY gene. It generally confirms the development of single-male reproductive systems.
The scenario in humans, the sex ration gets affected by the male parent's hormone level. Also, in XY sex evaluation system, the sperm of male takes part in X or Y chromosome whereas the ovum from female contributes to X chromosome. This greatly results in offspring - either male (XX) or female (XY).
Therefore, She creates the Punnett square cross below to show sex inheritance. She come to know that both parent determines the sex of a baby and it is when you put xx and xy on a punnet square there are equal amounts male and female.

what forces cause surface ocean circulation? what forces cause deep water circulation?
Answer:
ANS 1) Ocean currents can be caused by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes or storms. Currents are cohesive streams of seawater that circulate through the ocean.
ANS 2)n the deep ocean, the predominant driving force is differences in density, caused by salinity and temperature variations (increasing salinity and lowering the temperature of a fluid both increase its density). There is often confusion over the components of the circulation that are wind and density driven.

When population grows past the ecosystem’s carrying capacity, what happens to the population?
A. Continues to grow
B. The population starts to die off to return to carrying capacity
C. The population will go extinct due to lack of resources
D. The population grows, then finds a new carrying capacity.
Answer:B animals will die since there arent enough resources for everyone until there is enough for the remaining population to use
When Population growth past the ecosystem’s carrying capacity, then the population starts to die off to return to carrying capacity (Option B).
The carrying capacity refers to the maximum number of individuals of a population that can be supported by particular environmental conditions.Carrying capacity depends on both biotic factors (e.g., presence of predators, food availability, etc.) and abiotic factors (e.g., water availability, living space, etc).When a population passes its carrying capacity, then the environment becomes unsuitable for the individuals of that population to survive.In conclusion, when population growth past the ecosystem’s carrying capacity, then the population starts to die off to return to carrying capacity (Option B).

B. many evergreen trees, short moist summers, long snowy winters
C. long cool summers, short dark winters, migrating animals
D. treeless, permafrost, cold dark winters
Answer:
D. treeless, permafrost, cold dark winters
Explanation:
The correct answer would be D
Tundra is a habitat in which tree growth is hampered by cold temperatures and short growing seasons. Therefore, option (D) is correct.
What is a tundra?The freezing temperatures and short growing seasons of a tundra biome make it difficult for trees to develop in this sort of ecosystem.
Most of the time, it is cold, but in the summer, it can get quite warm. The winters on the tundra are long, dark, and very cold. For six to ten months of the year, temperatures are below 0 degrees Celsius. Because the temperatures are so low, there is a layer of frost below the surface. This is a layer of frozen ground.
Arctic tundra is found above the Arctic Circle in Alaska, Canada, Russia, Greenland, Iceland, and Scandinavia, or in Antarctica. Alpine tundra are high on mountains where nightly temperatures are below freezing.
Therefore, option (D) is correct.

An interglacial is a period of time that occurs between Ice Ages. During previous interglacials, the CO2 levels in the atmosphere were about 300 parts per million (ppm). In 2013, they were approximately 420 ppm. Rounding to the nearest percent, what is the percent increase in CO2 between these two time periods?
Answer:
40% increase
Explanation:
Percentage Increase Formula:
Percentage Increase=[(Final Value−Starting Value)/|Starting Value|] ×100%
To Calculate Percentage Increase:
1) Subtract final value (later value) minus starting value (initial value)
2) Divide that amount by the absolute value of the starting value (initial value)
3) Multiply by 100 to get percent increase
Keep in mind: If the percentage is negative, it means there was a decrease and not an increase.
So for your problem,
[(420-300)/300]*100% = 40% increase

Hope this helps!!
The four DNA strands that match the strand in the diagram by base pairing is GGTGACT. The correct option is A.
What is base pairing?A base pair, which consists of two nucleobases joined by hydrogen bonds, is the basic building block of double-stranded nucleic acids.
They contribute to the folded shape of both DNA and RNA and serve as the building blocks of the DNA double helix.
base pair of DNA. The nitrogen-containing bases adenine (A), thymine (T), and cytosine (C), as well as guanine (G), couple together under normal conditions.
The structure of DNA is created by the binding of these base pairs.
