what is the point on an object where the force of gravity is considered to act A. center of mass B. top of an object C. middle of the object D. center of gravity​

Answers

Answer:

D. Center of gravity.

Explanation:

Gravity always acts downward on every object on earth. Gravity multiplied by the object's mass produces a force called weight. Although the force of an object's weight acts downward on every particle of the object, it is usually considered to act as a single force through its balance point, or center of gravity.

Answer:

D. center of gravity​

the diagram shown represents a dihybrid cross between two pea plants heterozygous for both seed color and seed shape.

what is the phenotypic ratio of the offspring?
A. 1:1:1:2:2:2:2:4
B. 1:3:3:9
C. 1:4
D. 4:12


Answers

Answer:

1:3:3:9

Explanation:

There are 12 yellow seeds, from which 9 are smooth and 3 are rough.

There are 4 green seeds, from which 3 are smooth and only 1 is rough.

Both the appearance and color of the seeds is something you need to look out for when dealing with phenotypes.

The phenotypic ratio of this dihybrid cross will be 1:3:3:9.

What is phenotype?The term phenotype simply refers to a trait that may be observed. Pheno means observe  and is derived from the same root as "phenomenon." As a result, it's a sort of organism that can be seen, and it may relate to anything from a common characteristic like height or hair color to the presence or absence of disease.What is dihybrid cross?A mating experiment between two animals that are identically hybrid for two features is referred to as a dihybrid cross. A heterozygous organism is one that possesses two distinct alleles at the same genetic location, or locus.The cross between a homozygous pea plant with round yellow seeds and wrinkled green seeds is an example of a dihybrid cross.RRYY alleles are found in round yellow seeds, while rryy alleles are found in wrinkled green seeds.

Hence the correct option is B.

Explain what white light is and what it's made of, what do we see it as
PLZ HURRY

Answers

Answer:

The electromagnetic spectrum covers electromagnetic waves with frequencies ranging from below one hertz to above 1025 hertz, corresponding to wavelengths from thousands of kilometers down to a fraction of the size of an atomic nucleus. This frequency range is divided into separate bands, and the electromagnetic waves within each frequency band are called by different names; beginning at the low frequency (long wavelength) end of the spectrum these are: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays at the high-frequency (short wavelength) end. The electromagnetic waves in each of these bands have different characteristics, such as how they are produced, how they interact with matter, and their practical applications. The limit for long wavelengths is the size of the universe itself, while it is thought that the short wavelength limit is in the vicinity of the Planck length.[4] Gamma rays, X-rays, and high ultraviolet are classified as ionizing radiation as their photons have enough energy to ionize atoms, causing chemical reactions.

Explanation:

Answer:Each color has a different wavelength. Red has the longest wavelength, and violet has the shortest wavelength. When all the waves are seen together, they make white light. White light is actually made of all of the colors of the rainbow because it contains all wavelengths, and it is described as poly chromatic light.

A student examining an unknown cell under a microscope notes it has a cell wall, cytoplasm, and genetic information contained within a nuclear membrane. Which inference would be correct?



Since the cell possesses a cell wall and genetic information, it has to be an animal cell.

Since the cell contains genetic information, it has to be a bacteria cell and prokaryotic.

Since it possesses a cell wall and DNA contained in a nuclear membrane, the cell must be eukaryotic.

Since the DNA is contained in a membrane and not in the cytoplasm, the cell must be a plant cell

Answers

Answer:

Since it possesses a cell wall and DNA contained in a nuclear membrane, the cell must be eukaryotic

Explanation:

Since the cell possesses a cell wall and genetic information, it has to be an animal cell.

     -this is a plant cell because of the cell wall

Since the cell contains genetic information, it has to be a bacteria cell and prokaryotic.

     -prokaryotes don't have DNA contained in a nuclear membrane

Since it possesses a cell wall and DNA contained in a nuclear membrane, the cell must be eukaryotic.

     - DNA contained in a nuclear membrane --> eukaryototic

     - cell wall --> plant cells, which are eukaryotic

Since the DNA is contained in a membrane and not in the cytoplasm, the cell must be a plant cell

      -DNA is contained in a membrane should not lead to the conclusion that it's a plant cell, as it could be an animal cell too

Which statement about cell cycle checkpoints describes how this disease occurs?
A Dysfunctional checkpoints may lead to abnormal cell growth.
B Defective checkpoints result in death of a cell.
C Normal checkpoints assess damage to cancer cells.
D Cell checkpoints fail only in meiosis.
What would this be.

Answers

Answer:

A Dysfunctional checkpoints may lead to abnormal cell growth.

Explanation:

One of the hallmarks of cancer is unregulated cell proliferation. This means cells keep dividing, producing large numbers of often abnormal cells.

There are many of ways this can happen, such as increased signals telling the cells to divide, and dysfunctional cell cycle checkpoints that do not stop the cell from dividing. This leads to the accumulation of mutations and abnormal cell growth.

Mia conducted a five hour experiment. She used a liquid solution. The solution decreased by 9/8 ounces every hour for 5 hours. At the end of the experiment, there were 99/8 ounces of the solution remaining. How many ounces of solution did Mia start with? *

Answers

Given:

The solution decreased by [tex]\dfrac{9}{8}[/tex] ounces every hour for 5 hours.

Remaining solution at the end of the experiment = [tex]\dfrac{99}{8}[/tex] ounces.

To find:

The initial amount of solution.

Solution:

Let the initial amount of the solution be x.

The solution decreased by [tex]\dfrac{9}{8}[/tex] ounces every hour for 5 hours.

Total decreased amount  [tex]=\dfrac{9}{8}\times 5[/tex]

                                          [tex]=\dfrac{45}{8}[/tex]

Initial amount = Remining amount + Decreased amount of solution.

[tex]x=\dfrac{99}{8}+\dfrac{45}{8}[/tex]

[tex]x=\dfrac{99+45}{8}[/tex]

[tex]x=\dfrac{144}{8}[/tex]

[tex]x=18[/tex]

Therefore, the initial amount of solution is 18 ounces.
