Answer:

Based on similar appearance - traditional

Based on evolutionary relationships- modern

Known as cladistics- modern

Known as Linnaean classification- traditional

Explanation:

Linnaeus was a Swedish Botanist who was the first to classify organisms based on the structural similarities which organisms had. This method of classification came to be known as the Linnaean classification. Organisms which had more closer resemblances in structures and features had more groups or taxa in common.

The modern system of classification depends on the evolutionary history of organisms. It determines which organisms are more closely and have common ancestors in the past.

A prenatal client with vaginal bleeding is admitted to the labor unit. which signs or symptoms indicate placenta previa? select

adelina 88 [10]

The symptom and sign which indicate placenta previa here is Pinless vaginal bleeding.
Placenta previa is a condition where the placenta is covering the cervix or it is attached close to the cervix.
In various times of pregnancy, bleeding may occur. It can not be a serious complication. The cause of the bleeding may depend on the amount of pain or the time of bleeding in pregnancy.
In the first trimester, bleeding may occur and may be due to ectopic pregnancy, miscarriage, implantation of the placenta in the uterus or infection.
Bleeding in late pregnancy lets say twenty weeks can be due to placenta previa or placental abruption.

What drives deep ocean currents?

OLEGan [10]

Answer:

B) difference in water density

Explanation:

The deep ocean currents are the cold ocean currents. They appear in the Arctic and Antarctic circles. As the warm ocean currents come from the low latitudes toward the high latitudes, they bring in warmer water on the surface. They start to cool off though as the near the high latitudes, so gradually they become cold ocean currents. As they become cold, the water is sinking below the less dense warmer water that is coming from behind, making a turn in the opposite direction and moving as deep ocean current toward the low latitudes. Once it reaches the low latitudes, this water will get warmer, and it will move toward the high latitudes, and the process constantly continues.

If all of the offspring have roan coats—white hairs mixed into a base coat of red—what can be said about the red and white allel

madam [21]

Answer:

The alleles for red and white coat color are co-dominant.

Explanation:

Co-dominance is the condition when none of the allele of a gene is dominant. The heterozygous genotype exhibits traits of both alleles.

In the given example, the offspring have roan coat color in which white hairs are mixed into a base coat of red. Since both the alleles are expressed in heterozygous offspring, the alleles for red and white coat colors are co-dominant over each other.
