Answer:

This question lacks options, the options are:

A. All 270 tall plants were heterozygous

B. All 270 tall plants were homzygous.

C. Only 90 plants were homzygous.

D. All dwarf plants were homzygous.

The answer is D.

Explanation:

This question involves a single gene coding for height in pea plants. The allele for tallness (T) is dominant over that of dwarfness (t). This means that a dwarf plant can only be homzygous recessive (tt) while a tall plant can either be homzygous (TT) or heterozygous (Tt).

According to the question, two tall heterozygous pea plants were crossed i.e. Tt × Tt. Based on this cross, a phenotypic ratio of 3:1 is expected, which is in accordance with the 270 tall plants and 90 dwarf plants (360 total) that was obtained in the cross. Since dwarfism in pea plants is a recessive trait, this means that all the dwarf plants produced in this cross (90) were homzygous (tt).

The expected genotype resulting from the cross was that all dwarf plants were purebreed.

So, according to the given information, there is a cross between Tt × Tt.  A phenotypic ratio of 3:1 is desired, which is in accord with the 270 tall plants and 90 dwarf plants (360 total) that were got in the cross.

Since dwarfism in pea plants is a different feature, this means that all the dwarf plants produced in this cross (90) were (tt).

What are the 3 principles of Mendelian genetics?

The fundamental principles of Mendelian inheritance by Mendel's three laws:

Thus,  the cross was that all dwarf plants were purebreed.

Answer:

The correct answer is - chicks will not be able to survive in water.

Explanation:

Penguins spend the majority of their life in the water and for mating and moult they move to land and also lay their eggs on land. The wings or flippers of the chicks of these penguins are not as efficient as the wings of the adult penguins.

This makes it tough to survive on the waters for the chicks of penguins. Therefore they move to land even they are very clumsy on the land. The mating, molt and raising the chicks to few weeks are the prime reason.

Answer:

I think b is the correct answer of the question

Answer and Explanation:

Many elements can be responsible for this, among them, we can mention the presence and absence of predators in the different places on the rocky coast. This is because predators can influence not only the number of organisms found, but also the types of organisms.

Another element that may be the cause of this variability is the availability of resources necessary for the life of these organisms, in addition, the impact of the waves on the rocks, can cause the variability of the organisms, since some may not be able to resist the impact of the waves.

Answer:

Within the mitochondria, the import takes place post-translationally. The imported protein must be in an unfolded condition so that it can go through the mitochondria's import machinery. In the existence of methotrexate, the bound DHFR moiety remains in the folded state, and thus, stays on the surface of mitochondria.

It is witnessed that the presequence must be of the length of 55 amino acids to cover both the membranes of mitochondria and must be of about sixty amino acids length to associate with the mhsp70. If the presequence of this methotrexate bound DHFR is of seventy-five amino acids in length, it can associate with mhsp70 within the matrix, to initiate the ATP reliant import within the mitochondria. Due to the presence of various endocytic and intracellular sorting signals, multiple adaptors are essential.

Answer:

High amounts of fluoride

Explanation:

Teeth cleaning agents can contaminate one's blood with fluoride, something that it is only healthy to accumulate a small amount of.

A blood bank would refuse the blood of the potential donor because the cleaning agents of teeth significantly accumulate heavy metals in the blood of an individual.

Teeth are required to be cleaned regularly on their own. But if you are facing some problems like tooth decay you must have to consult with a dental hygienist in order to ensure the health of teeth and gums.

According to the context of this question, a dental hygienist uses a variety of cleaning agents while cleaning the teeth of a patient. Due to this, the accumulation of concentration of heavy metals like fluoride and lead is increased in the blood directly or indirectly.

Apart from this, this person also has genetic inheritance of tooth decay and other diseases. So, the blood bank refused to accept blood from a potential donor.

Explanation:

If the small-beaked birds can't eat, they will die

Answer:

Yes, it is vivid that the random variable has a binomial distribution

Explanation:

From the given information:

The probability of the plant with red flowers(p success) = 0.75

the sample size n = 100

Thus, the mean μ = np

= 100 ×0.75

= 75

The standard deviation can be calculated by using the formula:

[tex]SD = \sqrt{np(1-p)}[/tex]

[tex]SD = \sqrt{100 \times 0.75(1-0.75)}[/tex]

[tex]SD = \sqrt{100 \times 0.75(0.25)}[/tex]

[tex]SD = \sqrt{18.75}[/tex]

SD = 4.33

Answer:

What Darwin Never Knew”, is a stunning time line that details the theory of evolution formed by Charles Darwin, and the recent advancements made that answers some of the questions he simply could not. Darwin 's theory explained why today there are 9,000 kinds of birds, 350,000 kinds of beetles, 28,000 kinds of fish, and at least 2 million kinds of living species and counting. Darwin figured out that all species are connected, and he also realized that species evolved and adapted, but he did not know how. Darwin made a five year voyage on The HMS Beagle that would change his life, and all life as a matter of fact, forever.

Answer:

Explanation:

Reproduction may be asexual when one individual produces genetically identical offspring, or sexual when the genetic material from two individuals is combined to produce genetically diverse offspring. Asexual reproduction occurs through fission, budding, and fragmentation.

Answer:

3m/s²

Explanation:

a = v - u/t

Where;

a = acceleration (m/s²)

v = final velocity (m/s)

u = initial velocity (m/s)

t = time (s)

According to this question, a car is said to accelerate from 4 m/s to 16m/s in 4 seconds. This means that;

v = 16m/s

u = 4m/s

t = 4s

a = 16 - 4/4

a = 12/4

a = 3m/s²

Answer:

The single guide RNA forms hydrogen bonds with DNA, while Cas9 hydrolyzes phosphodiester bonds

Explanation:

The base pairing between nucleic acid strands (either DNA or RNA) is through hydrogen bonds between nucleotide bases. In DNA, Adenine always forms two hydrogen bonds with Thymine, while Guanine always forms three hydrogen bonds only with Cytosine. Moreover, adjacent nucleotides in the same strand are covalently linked by phosphodiester bonds (i.e., covalent bonds between the 5' phosphate group of one nucleotide and the 3'-OH group of another). The CRISPR/Cas9 genome editing systems make use of single-guide RNAs (sgRNAs) that interact with DNA through hydrogen bonds. These sgRNAs have perfect complementarity to the target DNAs in order to bind them. On the other hand, Cas9 is an enzyme that hydrolyzes phosphodiester bonds in both DNA strands very precisely and accurately by using a sgRNA complementary to a specific DNA sequence.
