Which organism is not a eukaryote?
Nikolay [14]

Answer:

Eukaryotes are organisms whose cells contain a nucleus and other membrane-bound organelles. There is a wide range of eukaryotic organisms, including all animals, plants, fungi, and protists, as well as most algae. Eukaryotes may be either single-celled or multicellular. Eukaryotes are differentiated from another class of organisms called prokaryotes by way of the presence of internal membranes that separate parts of the eukaryotic cell from the rest of the cytoplasm. These membrane-bound structures are called organelles.

In eukaryotes, the cell's genetic material, or DNA, is contained within an organelle called the nucleus, where it is organized in long molecules called chromosomes. Eukaryotic cells also contain other organelles, including mitochondria, which generate energy; the endoplasmic reticulum, which plays a role in the transport of proteins; and the Golgi apparatus, which sorts and packages proteins and lipids for transport throughout the cell. Plant cells additionally contain organelles called chloroplasts, which are used to collect energy from sunlight.

Melissa is studying a Gram-stained slide of curd bacteria. She sees many rod-shaped, violet-colored bacteria.What type of bacter
Serhud [2]

The answer is Paramecium.

The paramecium is a unicellular ciliated protozoan. They are often found in fresh water and brackish water areas. They have the elongated shaped that looks like a rod and has the color violet under the stain because it signifies that it is positive.

What happens at each step of a dichotomous key?<br><br> PLEASE HELP ME!
Yuki888 [10]

Oh I know this, It narrows down its characteristics here is an example:

The first step in the key will be organized the following way:

1. a. wings covered by an exoskeleton

b. wings not covered by an exoskeleton

Next, the statements need to lead the observer to the next step to narrow the identification further:

1. a. wings covered by an exoskeleton go to step 2

b. wings not covered by an exoskeleton .go to step 3

Step 2 needs to consist of a pair of statements that will allow for the identification of the ladybug and the grasshopper:

2. a. body has a round shape .ladybug

b<span>. body has an elongated shape .grasshopper</span>

A widows Peak is dominant over straight hairline the genotypes of The Offspring are WW, Ww, ww and ww. What are the phenotypes o
anastassius [24]

Phenotypes are the physical characteristics that result from the genotype, which is the genetic makeup of the organism. In this case, either straight hairline or Widow's peak will be the phenotype, as they are the physical characteristics being discussed.

The questions states that a Widow's peak is dominant over straight hairline. So we are going to assume that the Widow's peak allele is W (dominant), and the straight hairline allele is w (recessive).

A dominant allele will mask the presence of a recessive allele unless both of the alleles are both recessive (both ww).

So for the WW genotype, we are going to see the dominant phenotype: Widow's peak.

For the Ww genotype, we are also going to see the dominant phenotype since the dominant allele is going to mask the presence of the recessive allele, so we are going to see: Widow's peak.

Lastly, for the ww genotype, we are going to now see the recessive phenotype, since both alleles are recessive: straight hairline. Note that their are two of these type of offspring as stated in the question.
