Explanation:
Which of these events can lead to an increase in the population size of mice?
a. Some mice emigrate (leave) in search of food
b. Cats, owls, and snakes are added
c. More mice are born than die
d. A large number of mice die because of a forest fire
e. Cheese shortage
This means the birth rate would exceed the death rate, to make a positive growth rate in the population. So overall, the population will go up if more mice are born compared to those that die off.
Choices A, B, D and E all describe factors that would either kill mice or push them out of the habitat. Either way, these answer choices would have a decrease in population rather than increase. So we can eliminate these answer choices.

Inversion of DNA sequences within chromosomes is a common process in evolution. The following gene arrangements in a particular chromosome are found in four different species: First sequence: STUVWX Second sequence: UVXTSW Third sequence: UVWSTX Fourth sequence: SWVUTX Assuming that the arrangement in the first sequence is the ancestor/reference arrangement, in what evolutionary order did the four species arise, such that the fewest number of inversions occur between each species (place the first sequence as the earliest species in your ordering)2341
Answer:
The correct answer is - 1, 4, 3, 2.
Explanation:
It is given that the first sequence represents the earliest or ancestor species therefore, the first sequence would be - STUVWX
After the inversion, the highlighted sequence of the first sequence STUVWX gives rise to the second sequence as:
STUVWX
SWVUTX
Thus the second sequence after Ist inversion would be SWVUTX
2nd inversion, Third sequence:
SWVUTX
UVWSTX
Thus the third sequence after 2nd inversion is UVWSTX
3rd inversion, fourth sequence:
UVWSTX
UVXTSW
Thus, the fourth sequence after 3rd inversion is UVXTSW

What is the relationship between the levels of CO2 in the atmosphere and the levels of CO2 in the ocean?
Answer:
Because of human-driven increased levels of carbon dioxide in the atmosphere, there is more CO2 dissolving into the ocean. The ocean's average pH is now around 8.1 , which is basic (or alkaline), but as the ocean continues to absorb more CO2, the pH decreases and the ocean becomes more acidic.

No. Some specialized cells, such as skin cells, divide much more rapidly than other
specialized cells
No. Some specialized cells, such as skin cells, divide much more slowly than other
specialized cells.
Answer:
Yes, All of the cells divide at approximately the same rate, although they may divide at different times
Those organisms which are made up of more than one cell are called multicellular organisms.
These are a few examples of multicellular organisms:-
PlantsAnimalsFungiMulticellularity helps them to perform various work at the same time. To maintain the same number of cells in an organism, its body starts cell division.
It is not necessary for the host to divide all the cells at the same time.
Hence the correct option is Yes. All of the cells divide at approximately the same rate, although they may divide at different times.

With a ruler, draw a line that is 20 cm long. Divide the line into five, 4-cm segments. On a scale of each segment representing one billion years, label the following events in the history of Earth:
a. formation of the earth
b. origin of life
c. evolution of photosynthesis
d. evolution of eukaryotes
e. evolution of multi-cellular life
f. the Cambrian explosion
g. first vertebrate land animals
h. evolution of dinosaurs
i. evolution of human beings
Solution:
The first traces of the life that existed on the earth can be traced back to about as old as 4.2 billion years. It indicates that life has evolved around 200 million years ago after the first appearance of the liquid water.
The origin of the life on earth is a natural process and is a series of evolution what we see today. Firstly earth was formed by dust and smoke particles and then different forms of life began to evolved on the earth.
The events of the evolution in the history of the earth is shown on the following number line below :
A chest radiograph of an asymptomatic 37-year-old man showed a 3-cm nodule in the middle lobe of the right lung. The nodule was excised with a pulmonary wedge resection, and sectioning showed the nodule to be sharply circumscribed with a soft, white center. Culture of tissue from the nodule grew Mycobacterium tuberculosis. Which of the following pathologic processes has most likely occurred in this nodule? a. lipid acummulation b. liqufactive necrosis c. caseous necrosis d. coagulative necrosis e. gangreous necrosis f. apoptosis g. apoptosis h. fat necrosis
Answer:
caseous necrosis
Explanation:
The pathologic process that most likely occurred to this nodule would be caseous necrosis. This occurs at the time of death of a some cells but it is a very unique scenario in which the cell maintains a soft and white proteinaceous dead cell mass, just like in this scenario. This type of cell death usually occurs in lymph nodes but can occur in any cell in the body including in the lung.
In grammatically correct sentences trace the path of the products of photosynthesis as they exit the leaf.
Answer:
The correct answer is -
O2 - through the stomata
Glucose - through the phloem in the veins
H2O- through stomata
Explanation:
In the process of photosynthesis, plants capture light energy to initiate a chemical reaction that uses CO2 and H2O as reactants and converted them into oxygen and sugar or glucose as products. Thus, oxygen and glucose are the products form in photosynthesis.
These products are carried through various paths to the new location to get utilized. Glucose is carried by the phloem in the veins out to the plant whereas oxygen and water diffuse into the environment through stomata.

Answer:
- The building blocks of DNA molecules are amino acids. False
- DNA molecules contain a 5-carbon sugar called deoxyribose. True
- The nitrogen bases found in DNA molecules include adenine, cytosine, guanine, and thymine. True
Explanation:
The building blocks of the deoxyribonucleic acid (DNA) are nucleotides, while amino acids are the building blocks of proteins. Each nucleotide consists of one of four possible nitrogenous bases: two purines (i.e., adenine and guanine) and two pyrimidines (i.e., cytosine and thymine). In DNA, each nucleotide consists of one of these four nitrogenous bases, a five-carbon sugar molecule (called deoxyribose), and a phosphate group. The DNA molecule has a double-helix structure, where nitrogenous bases are inside the double helix while sugars and phosphates are outside. In DNA, cytosine always pairs with guanine and thymine always pairs with adenine.

Why are feathers "easy to repair"?
Answer: The feathers are easy to repair as the cells of birds help in replacement of damaged and old feathers.
Explanation:
The follicles of the feathers have regenerating cells that help in regrowing the feathers when the feathers are damaged and require to be replaced. The regrowth of feathers is a natural process that happens in all birds. The feathers are replaced by one or two molt seasons per year. In these seasons they shed their feathers and new feathers reappear. The newly growing feathers are stiff, and hard similar to nails.
