Answer:
Climate change not only affects ecosystems and species directly, it also interacts with other human stressors such as development. Although some stressors cause only minor impacts when acting alone, their cumulative impact may lead to dramatic ecological changes.
Explanation:
In cocker spaniels, black coat color ( B) is dominant over red ( b), and solid color ( S) is dominant over spotted ( s). In the F 2 generation of a cross between BB ss with bb SS, what fraction of the offspring would be expected to be black and spotted
Answer:
The correct answer is -3/16
Explanation:
The cross between BBss and bbSS In cocker spaniels will form gametes that are - Bs and bS. As it is given that black coat color ( B) is dominant over red ( b), and solid color ( S) is dominant over spotted ( s) then f1 gen would be :
Bs Bs
bS BbSs BbSs
bS BbSs BbSs
Now F2 generation;
BS Bs bS bs
BS BBSS BBSs BbSS BbSs
Bs BBSs BBss BbSs Bbss
bS BbSS BbSs bbSS bbSs
bs BbSs Bbss bbSs bbss
Here black-spotted that is possible only in two cases, BBss or Bbss, are 3/16
The energy that fuels food webs begins as light energy from the sun. True or False
Answer: i think its true. ( based of information i got)
Explanation: The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers such as plants, algae, and cyanobacteria use the energy from sunlight to make organic matter from carbon dioxide and water. This establishes the beginning of energy flow through almost all food webs. also A food web consists of many food chains. A food chain only follows just one path as animals find food. eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. A food web shows the many different paths plants and animals are connected.

Why are Mercury Seasons difficult to determine? Explain why.
Rachel drove 300 miles from her home to Philadelphia to visit her sister and then returned home a week later. At the end of the trip what was her displacement and distance traveled in that order
Answer:
The correct answer would be - zero miles, 600 miles.
Explanation:
She started from the same point and after the trip, she ended it on the same point in Philadelphia therefore the displacement is expected to be zero.
The distance she traveled would be 2 into 300 miles as she traveled to her sister and traveled back from there so
Distance = 2*300
= 600 miles.
Thus, the correct answer would be - 0 and 600 miles.

3. There are multiple types of mutations in DNA.
mutations occur when a single base is
changed to a different base pair.
mutations remove one or more bases from a segment of DNA,
resulting in a frameshift mutation.
mutations are also considered frameshift mutations, and occur when
one or more extra bases are added to a segment of DNA.
Check Answer
Answer:
substitution, deletion, insertion (in that order)
Explanation:
I did the assignment-
Mutations occur when a single base is changed to a different base pair; mutations remove one or more bases from a segment of DNA, resulting in a frameshift mutation, so this is also correct in other statements.
What is the significance of the DNA mutation?Mutations in DNA lie in their ability to alter the genetic information, and that altered information is passed on to next generations while Some mutations have no effect on the function of the proteins, but some have serious effects. It helps in the evolution process by providing a mechanism for the development of new traits, etc., in nature, so it has a significant role in it.
Hence, mutations occur when a single base is changed to a different base pair; mutations remove one or more bases from a segment of DNA, resulting in a frameshift mutation, so this is also correct in other statements.

Chi square= ∑ ((O-E)²/E)
Where,
∑ is the sum of the terms O refers to the Observed number of individual E refers to the Expected numbers of individualsX² = ∑ ((O-E)²/E)
X² = (0.002/269.58) + (65.61/89.86) + (15.2/89.86) + (3.61/89.86) + (8.41/29.95) + (16.81/29.95) + (0.01/29.95) + (9/9.98)
X² = 0.0000074 + 0.73 + 0.17 + 0.04 + 0.28 + 0.561 + 0.0003 + 0.9
X² = 2.6813

A woman with a straight hairline has as child with a man who is heterozygous
and has a widow's peak.
What is the mother's genotype?
Answer:
aa
Explanation:
A widow's peak is the dominant genotype so one must not have that trait. If it was presented then the woman would have the genotype.
A widow's peak is dominant so the man would be either AA or Aa. Since it stated that his is heterozygous (Hetero meaning two different), his genotype would be Aa (again since a widow's peak is the dominant, it only needs one dominant genotype)

Answer: the second answer
Explanation:
As with Part H. you have a total body concentration of 300 mOsM and body volume of 3 liters. You now add 2 liters of a 500 mOsM solution. The solution is equal parts NaCI (nonpenetrating) and urea (penetrating), so it has 250 mosmol/L NaCI and 250 mosmol/L urea. Answer the following questions about your new solution:
Drag the terms on the left to the appropriate blanks on the right to complete the sentences.
The solution is_______ osmotic to the body.
What is the concentration of nonpenetrating solutes (NP) in the solution?
What is the internal concentration of the body's cells? (All intracellular solutes are nonpenetrating.)
When the cells reach equilibrium after addition of the solution to the body, has cell volume increased, decreased, or stayed the same?
Based on your answer regarding water movement, the solution was ____ tonic to the body's cells.
increased

300 mosmol/L
Stayed the same
300 mosmol/L
Hypo
lso
decreased
stayed the same
Answer:
- The solution is hyperosmotic to the body.
- What is the concentration of nonpenetrating solutes (NP) in the solution? 500 mosmol/L
- What is the internal concentration of the body's cells? (All intracellular solutes are nonpenetrating.) 300 mosmol/L
- When the cells reach equilibrium after addition of the solution to the body, has cell volume increased, decreased, or stayed the same? increased
- Based on your answer regarding water movement, the solution was hypotonic to the body's cells.
Explanation:
A hyperosmotic (or hypertonic) solution is a solution with a greater solute concentration. If a cell is placed in a hyperosmotic solution the water will leave the cell and the cell will shrink. Conversely, a hypotonic solution is a solution that has a lower concentration of solute. If a cell is placed in a hypotonic solution the water will enter the cell through osmosis and the cell increases in size. In this case, the NaCl is a non-penetrating solute, and thereby the concentration in the body's cells maintains constant. Moreover, urea is a penetrating solute, thereby it will penetrate in the cells until the equilibrium is reached (i.e., the cells will increase in volume).
How can you use genetics to study human inheritance?
Answer:
by analyzing how genes influence the development of phenotypic traits, i.e., by determining the association between phenotypic traits and changes in DNA sequence
Explanation:
Genetics is a discipline that studies how genetic variation, i.e., the variation in the Deoxiriibunicleinc acid (DNA) molecule, is associated with the transmission of heredity, and how the environment influences this process. The DNA is a molecule that carries the instructions to perform all metabolic functions (eg., reproduction, development, growth, etc). Thus, advancements in genetics enabled us to decipher how phenotypic traits pass from parents/ancestors to their offspring/descendence. Genes are segments of DNA that carry the information (genetic information) to determine each phenotypic trait. During reproduction, genes are passed from one generation to the next, thereby transmitting this information across generations.
