Which of the following does not accurately describe movement within plants?

Answers

Answer 1

Answer: A. Transpiration is the only force that drives water movement within a plant.

Normally there are two kinds of roots and they are taproot and fibrous roots. In case of taproots the main root goes downwards and smaller roots branches out of it. In case of taproots, it is true that the spread of roots is smaller than the depth of the roots. In case of fibrous roots, the spread of roots is greater than that of the depth of the roots. A wig tree is an example of a plant having taproot. in the wig tree the root can go to a depth of around 120 meters.

What are two of the processes that move tectonic plates over the surface of earth

Answers

tectonic plates float on amass of melted lava. its very hot and produces gases. these gases tend to move the plates with the compression becomes very high and the gases do not find an exit.the other reason is the plates themselves tend to move. because of the temprature gradient. the plates are hotter on the lower side which forces the plates to move up. and they are colder on the outside,which forces the plates to move downward..this is the other reason why the plates move

Similarities between mutualism commensalism and parasitism

Answers

They are all different types of symbiosis. Mutualism is where both organisms benefit from each other, commensalism is where one organism benefits but the other is unaffected, finally parasitism is where one organism benefits and the other is harmed.

What determines the inherited traits an organism has? A.the proteins produced by a cell

B.the number of chromosomes in a cell

C.the size of the chromosomes

D.the genes of its chromosomes

Answers

Answer: The correct answer is-

D.the genes of its chromosomes.

Inherited traits are the characteristics of an organism that are transferred from parents to their next generation through genetic material (DNA).

For Example- Eye color, hair color, skin tone.

Gene corresponds to the unit of heredity that can be described as the segment of DNA that codes for a particular protein. They are present on the chromosome (thredlike structures composed of DNA).

The protein that is formed by gene, depicts a specific trait of the organism.

Thus, inherited trait of an organism are determined by the genes, located on the chromosome.

The genes of its chromosomes determines the inherited traits an organism has. Therefore, option (D) is correct.

Inherited traits are the characteristics of an organism that are passed down from one generation to the next through DNA. Some examples are the colour of your skin, your hair, and your eyes.

The unit of heredity known as a gene is defined as the section of DNA that codes for a specific protein. They can be found on the chromosomes, which are DNA-based thred-like structures.

The gene-produced protein represents a particular characteristic of the organism. Thus, the genes found on chromosomes control the inherited traits of an organism.

Suppose that a dominant allele (P) codes for a polka-dot tail and a recessive allele (p) codes for a solid colored tail. If two heterozygous individuals with polka-dot tails mate, what's the probability of the phenotype and genotype combinations of the offspring?A. 25 percent chance of a polka-dot tail and 75 percent chance of a solid colored tail (25 percent PP; 50 percent Pp; 25 percent pp)
B. 75 percent chance of a polka-dot tail and 25 percent chance of a solid colored tail (25 percent PP; 50 percent Pp; 25 percent pp)
C. 75 percent chance of a polka-dot tail and 25 percent chance of a solid colored tail (75 percent Pp; 25 percent pp)
D. 50 percent chance of a polka-dot tail and 50 percent chance of a solid colored tail (50 percent PP; 50 percent pp)

Answers

The answer is B. 75 percent chance of a polka-dot tail and 25 percent chance of a solid colored tail (25 percent PP; 50 percent Pp; 25 percent pp)

If P represents dominant allele (a polka-dot tail), p represents recessive allele (a solid colored tail), then heterozygous individuals have Pp genotype. All alleles will combine each other:

Parental generation: Pp x Pp
Offspring: PP Pp Pp pp

Thus, the probability of PP genotype is 1/4 (there is only 1 of total 4 possible genotypes), which is 25%. The probability of Pp genotype is 1/2 or 50%, and the probability of pp genotype is 1/2 or 25%.

Talking of phenotypes, the P allele is dominant and each genotype containing P allele will have the polka-dot phenotype. In this case, there are 3 out of 4 genotypes containing P allele - 1 PP and 2 Pp. So, the probability of the polka-dot tail is 3/4 or 75%, leaving the probability of the solid color tail 1/4 or 25%.
