A pluripotent stem cell can form only one type of cell. PLEASE HELP!! TRUE OR FALSE
Answer:
False
Explanation:
These embryonic stem cells are pluripotent. This means that they can turn into more than one type of cell.
Do two organisms that express the same trait have to
carry the same genetic information?
Answer:
Any organism that receives the same genetic information for a trait from each parent. Also, any organism that has either two dominant or two recessive genes dominant trait, therefore the trait will show in a hybrid.
In what direction do substances diffuse across the cell
membrane?
Answer:
Since diffusion moves materials from an area of higher concentration to the lower, it is described as moving solutes "down the concentration gradient." The end result of diffusion is an equal concentration, or equilibrium, of molecules on both sides of the membrane.

Explanation:
Describe what would happen to mass and weight if you were on
the moon.
Answer:
the moon's weight is less than the Earth so the moon will not pull objects toward itself at the strength of the Earth. This means that if you went to the moon you would weigh less, even though your mass stays the same

Two true-breeding stocks of pea plants are crossed. One parent has red, axial flowers and the other has white, terminal flowers; all of the first generation of the offspring have red, axial flowers. The genes for flower color and location assort independently. If 1,000 second generation offspring resulted from the cross, approximately how many of them would you expect to have red, terminal flowers
Answer: 750
Explanation:
Based off the first two sentences, we can conclude that red is the dominant allele and white is the recessive allele.
Let's say R = red and r = white.
The genoytypes of the parents are RR and rr. The genotype of the first generation are all Rr
The punnet square for the second generation is:
R r
R RR Rr
r Rr rr
We can see 3/4 crosses give us red. Now we can multiply 3/4 and 1000 to get 750.

What is a similarity between the temperate climate zone and polar climate zone?
A) Both of the climate zones have warm and hot weather and lots of precipitation.
B) In both polar and temperate zones, the temperature of the warmest month is about 18°C.
C) The temperature can get to 0°C in both temperate and polar climate zones.
D) The temperate and polar climate zones both usually have 150 cm of precipitation.
In both the polar and temperate zones, the temperature of the warmest month is about 18°C. So, the correct option is B.
What are Polar and Temperate zones?Temperate regions are defined as regions with mild temperatures that lie between the subtropical and polar regions where the two regions between the Tropic of Capricorn and the Antarctic Circle or the Tropic of Cancer and the Arctic Circle are called temperate regions.
The polar region is defined as the area around the North Pole or the South Pole, where the North Polar Region consists mainly of flotation and pack ice, 7–10 feet (2–3 m) thick which floats on the Arctic Ocean and is surrounded by land. In both zones, the temperature of the warmest month is about 18°C.
Therefore, the correct option is B.

A. Describe the difference between gradualism and punctuated equilibrium.
B. Describe the conditions under which new species may arise.
C. Explain the difference between allopatric and sympatric speciation.
D. Describe the role of prezygotic and postzygotic barriers in the process of speciation.
A. Both theories describe the rates of speciation. For Gradualism, changes in species is slow and gradual, occurring in small periodic changes in the gene pool, whereas for Punctuated Equilibrium, evolution occurs in spurts of relatively rapid change with long periods of non-change.
B. New species arise through a process called speciation. In speciation, an ancestral species splits into two or more descendant species that are genetically different from one another and can no longer interbreed.
C. Allopatric speciation occurs when two species are living in separate environments and therefore there is no gene flow between the populations. ... Sympatric speciation occurs when two species are living in the same environment.
D. Reproductive isolation is a mechanism that keeps species from mating with others. Prezygotic isolation prevents the fertilization of eggs while postzygotic isolation prevents the formation of fertile offspring. ... Postzygotic mechanisms include hybrid inviability, hybrid sterility and hybrid "breakdown."
True or fasle? Cells have to divide when becoming too large so that the cell can
maintain homeostasis.
Answer:
True
Explanation:
The cell has to dividewhen it comes to large, because the cell wall is not big enoughtpo maintain all inside the cell when to large.

In the 1950s, Stanley Miller performed experiments to study the origins of life. He created an atmosphere rich in methane, hydrogen, ammonia, water, and simulated lightning. Which substances were most likely produced during Miller’s experiments?
A. protists
B. bacteria
C. amino acids
D. RNA strands
Answer:
c. amino acids
Explanation:
The substances most likely produced during Miller's experiments would be amino acids.
In their simulation of the early atmosphere, Stanley Miller was able to obtain a mixture of organic compounds in the broth with the major one being amino acids.
The discovery of Stanley Miller gave further credence to the chemosynthetic theory of the origin of life because amino acids form the building blocks of proteins and proteins are essential for the onset of life.

A) They both cause animals to move where there are less resources.
B) They both affect prey more than they affect predators.
C) They can both cause animals to move to a new environment.
D) They both affect plants more than they affect animals.
The similarity between reduced space and a lack of food is the option "C" they can both cause animals to move to a new environment.
How does population affect resources?Prompt population growth continues to be a significant underlying force of environmental degradation and a hazard to the sustainable use of natural resources.
It diminishes the quality and quantity of natural resources through overexploitation, intensive farming and land fragmentation.

A high population of greater prairie chickens once inhabited the prairies of Illinois. The conversion of the prairies into agricultural land caused the chickens to lose their habitat. Studies have concluded that this change greatly reduced the greater prairie chicken population. The habitat loss also resulted in a decrease in the population’s genetic variation.
Which change in the gene pool occurred in the greater prairie chicken population?
gene mutation
gene flow
genetic drift
genetic resistance
Answer:
The answer is C. genetic drift
