Liam knew that all living things have common characteristics. His new baby brother made him think about how different all the types of living things were. Which of the following is not a common characteristic shared by all living things?
A. made of a cell or cells
B. made of similar chemicals
C. respond to surroundings
D. spontaneously generate
Answer:
Option D) - Spontaneously generate.
Answer:
Spontaneously generate
Explanation:
all living things have cells, are similar chemically (like have water) and respond to surroundings.
Spontaneous generation refers to an obsolete body of thought on the ordinary formation of living organisms without descent from similar organisms. The theory of spontaneous generation held that living creatures could arise from nonliving matter and that such processes were commonplace and regular.
Gregor Mendel crosses a true-breeding tall plants (TT) with a true-breeding short plant (tt). What are the predicted phenotypes for the offspring ?
a. all tall
b. all short
c. ratio of 1 tall : 1 short
d. ratio of 3 tall : 1 short
Answer:
a. all tall:
Explanation:
Tall plants (TT) are the more dominate trait. Use the Pundett square (I will try to recreate it as best as possible but it will not look good):
t t
T Tt Tt
T Tt Tt
As you can (kind of) tell, T appears on all offsprings, and as the dominate trait, it will take over 100% of the time.
The next generation (depending on who you are breeding them with), will have a different result.

Which of these locations is most likely to experience moderate climate throughout the year?
Answer:
b
Explanation:
The location that is most likely to experience moderate climate throughout the year is C.
The location C of the map will experience moderate climate because it is a coastal region of the map.
Moderate climate weather is described as a weather condition that occurs during the day, as cool air from sea rush towards the land and during night, as cool air from the land rush towards sea.
Because location C is a coastal region which means that the location is surrounded by land which better absorbs and radiates heat much faster than sea.
Therefore, the location that is most likely to experience moderate climate throughout the year is C.

Explanation:
Arctic ice retreat is threatening many species in this ecosystem. Their resources are being cut and they are needing to find new ways to survive. Do you think in your lifetime you will see drastic effects to the species in this ecosystem and why? Will that affect other ecosystems?
Answer:
no
Explanation:because they will find new ways to survive in the environment
Answer:
We are already seeing drastic effects to the ecosystem and it's wide assortment of species. Animals such as polar bears, and seals are losing their breeding and hunting grounds. Polar bears in particular are losing their ways to catch seals for food and interbreeding with grizzly bears. Fish and whales from warmer parts of the world are starting to move up north and are becoming invasive. Most importantly, since cold water from the melting ice are mixing with ocean currents, global climates and weather systems are changing course. Ultimately, in about 500 years, there could be a large Global Climatic Shift that may put us into another Ice Age.

Which statement about fossils could be used as evidence that
evolution by natural selection has been in effect for millions of
years?
Fossils found in higher layers of rock are older than those
found in lower layers.
Fossils found in lower layers of rock are more complex than
those found in higher layers.
© Fossils of current species have been found throughout rock
layers that are billions of years old.
0 Fossils of species that no longer exist but are ancestors of
current species have been found in rock layers.
Fossils of species that no longer exist but are ancestors of current species have been found in rock layers. Thus, the correct option is D.
What are Fossil fuels?A fossil fuel is a hydrocarbon-containing material which is formed naturally in the Earth's crust from the remains of dead organisms such as plants and animals which are extracted and burned as a fuel. The main fossil fuels which are present in the earth's crust include coal, oil, and natural gas.
The evolution of species is easily confirmed by the presence of fossils of the most diverse species of the living beings in the world. This is because, fossils are the records of species which do not currently exist, however there are existed millions of years ago and are similar to the current species, being their ancestors.
Therefore, the correct option is D.
