Answer:

In insects such as cockroach, grasshopper

Explanation:

Insects such as grasshopper has open circulatory, in them the body fluid is the hemolymph. The hemolymph does contain any respiratory pigment. It bathes the organs directly as it is pumped between open spaces in the body.

Thus, in insects, the blood and the interstitial fluid considered to be the same body fluid?

What term is used to describe bacterial cells that can naturally take up dna from their environment?

Maru [420]

<h2>The correct answer is: Competent cells</h2>

Explanation:

Bacterial cells have the capability of incorporating foreign naked DNA or deoxyribonucleic acid fragments from the environment or the exterior of the cell to the interior of the cell. This process is known as Transformation.
The bacterial cells which are able to undergo transformation are called Competent bacterial cells.
Some of the bacterial cells are naturally competent like<em> Bacillus subtilis, Streptocossus pneumoniae</em> while others like <em>Escherishia coli </em>need to be chemically treated to make them artificially competent.
In natural competence, the foreign DNA from the cell exterior is incorporated into the cell interior through specific protein complexes present in the plasma membrane of the bacterial cells.
In artificial competence, the negative charge on foreign DNA is masked by positively charged calcium ions (so that it is not repelled by the negative charge of the lipid bilayer of the bacterial cell plasma membrane) and then small pores are created in the lipid bilayer of the plasma membrane of the bacterial cells by giving a heat shock to the cells. This results in the uptake of the DNA by the bacterial cells.

If you made a Punnett square showing Gregor Mendel’s cross between true-breeding tall plants and true-breeding short plants, the

nekit [7.7K]

Answer:

Explanation:

Assume that allele A is the dominant allele that produces the dominant phenotype (tall) in plants that have at least one allele A, and allele a is the recessive allele that produces the recessive phenotype (short) in plants that have two alleles a.

In the parental generation, a true-breeding tall plant has the AA genotype (phenotype: tall), and a true-breeding short plant has the aa genotype (phenotype: short).

We have the Gregor Mendel's cross as in the image attached here.

All of the F1 generation (offspring plants) have the Aa heterozygous genotype, and therefore, they are all tall.

The answer is c (the offspring plants have a genotype that was different from that of both parents).

Lynna [10]

Answer: 2.81 x 10∧14 baterias after 16 hours.

Explanation:

Hi, first we have to find how many 20 minute intervals are in 16 hours.

If 1 hour = 60 min, 16hours = 960 minutes (16 h x 60 min / 1 h)

If we divide the 960 minutes (16 hours) by 20 minutes we obtain 48. (960/48)

There are 48 twenty minutes intervals in 16 hours.

Now we have to apply the exponential growth formula:

P (t) = Po (1 +r) ∧t

Where:

P (t) = population at time t

P (0) = initial population (1)

r = growth rate (1)

t = time (48)

Replacing with the values given:

P (t) = 1 (1 + 1) ∧48= 2.81 x 10∧14

2.81 x 10∧14 baterias after 16 hours.
