Biology
1 answer:
MissTica4 years ago
7 0

Answer:The integral of acceleration = velocity

Step 1.  write a linear equation for the graph ...  a =  some function of t  --

  (hint -- from alg 1 , use y = mx + b)  

Step 2.  --- integrate to get a velocity equation.  use the initial condition to find C  ...  (At t = 0, the velocity of the car is 0)

 ---  the integral of velocity  =  displacement (or position)

step 3.  integrate the velocity equation from step 2 to get a position vs time equation

--- use the initial condition to find C  (At t = 0, its position is 10)

step 4.  answer the question

Which of the following statements are true for both the recrystallization and replacement modes of preservation? Choose one or m
vladimir2022 [97]

A similarity in both recrystallization and replacement modes of preservation is that delicate tissue and organs are not preserved.

<h3>What are recrystallization and replacement modes of preservation?</h3>

Recrystallization is a mode of preservation of fossils in which the internal structure of the fossils is changed by addition of more minerals to form larger crystal of the same material.

Replacement is a mode of preservation in which new material replaces the original material in the fossil.

In both methods of preservation, delicate tissue and organs are not preserved.

Therefore, a similarity in both recrystallization and replacement modes of preservation is that delicate tissue and organs are not preserved.

If you look at the karyotypes of person a and person b and discover that they look alike, what can you infer is the same about t
nataly862011 [7]

Answer:

They belong to the same species

Explanation:

A karyotype is an image of the chromosomes of a cell usually taken by an atomic microscope in a cell arrested in the prophase stage of mitosis –because the chromatin is well condensed.

It is difficult to discern the difference between individuals of the same species using karyotype unless in exceptions of chromosomal disorders like Klinefelter's syndrome and Turners syndrome, and etcetera.

However different species will most likely differ in the number of chromosomes, the chromosomal sizes and their arms lengths.

3.When on a weight-gain diet, untrained men tend to initially gain about 2 pounds of muscle per month, and 20 pounds or more per year. This is because there is more area in the body available for muscle growth that's why muscle fibers are easily developed and recruited to perform muscle contractions.

An acidic solution of pH 5 has<br> TIMES as many hydrogen ions (H+) as does a solution of pH 6.
Artyom0805 [142]

The difference in concentration of hydrogen Ions between pH5 and pH6 is - x 10.

The pH scale is a scale or measure to find the strength of acidity or the basic nature of a solution or substance. pH 1 is acidic and pH 14 is the most basic on the scale.

  • The concentration of hydrogen ions is inversely related to its pH
  • More hydrogen ions present, the lower the pH
  • The fewer hydrogen ions, the higher the pH We know,

pH = -log(H+) then,    

=> 5 = -log (H+)

=> H+ = 10^{-5} (for pH = 5)    

=> pH = -log(H+)  

=> 6 = -log (H+)  

=> H+ = 10^{-6}  (for pH = 6)  

Thus, The substance with the lower pH (5) has 10 times as many hydrogen ions per volume of water.

Recall that DNA is
Mashutka [201]

Answer:

25 nucleotide sequence pair

Explanation:

There are four nucleotide sequence pair present in DNA. and if we have 100 nucleotide so 25 nucleotide sequence pairs will be formed and each pair contains adenine (A), cytosine (C), guanine (G), and thymine (T).

Cytosine nucleotide paired with guanine nucleotide and Adenine nucleotide paired with thymine nucleotide . They have hydrogen bonds between each bases.
