D

Explanation:

L&D is divided up into 3 parts.

1st is when the cervix dilates from 1cm to 10 cm. Can last from anywhere from 10 hours to a couple days.

2nd is shorter and is the pushing phase. Can last anywhere from 5 minutes to 3 hours.

The correct answer is C. Dilation, strong contractions, and delivery of the baby and the placenta

Explanation:

Labor and delivery is divided into three main stages: the first stage includes the latent phase in which cervical dilation begins (3 to 5 cm) along with mild contractions and the active phase in which strong contractions occur along with complete or almost complete dilation; the second phase is the fetus expulsion or delivery in which the cervix is fully dilated and the baby is born; and the third stage is the delivery or expulsion of the placenta that occurs as the placenta separates from the uterus and is expulsed through mild contractions. Thus, stages of labor and delivery are dilation, strong contractions, and delivery of the baby and the placenta.

vesna_86 [32]

Answer: The genotype ratio is 2Ff : 2ff

The phenotype ratio is two normal feathered birds to two silky feathered birds.

Explanation: Let F represent the gene for normal feather and f represent the gene for silky feather. F is dominant while f is recessive, therefore a male that is hybrid for trait of normal feather is heterozygous and will have a genotype of Ff, a female that is homozygous for silky feather will have a genotype of ff.

A cross between Ff and ff will yield 2Ff birds and 2ff birds. Since F is dominant, a bird having genotype of Ff will manifest outwardly as blue feathered birds while ff will manifest outwardly as silky feathered birds because f is recessive and must occur in a homozygous condition in order to manifest phenotypically. Therefore, the genotype ratio is 2Ff: 2ff.

skad [1K]

Answer:

At some point the bond between the amino acid and the substrate must break.

Explanation:

Enzymes are the biocatalyst that can increase the speed of the biochemical reactions of the living organisms. All enzymes are made of proteins except ribozymes.

During the catalytic process, the enzymes can form covalent modification. This is only possible when the bonds between the substrate and amino acid is broken. This breaking and formation of bond is important so that enzyme can makes the substrate free and the steps can be repeated again.

Answer: Frontal Lobe of the brain

Explanation:

The frontal lobe of the brain is involved in reasoning, motor control, emotion, and language. It contains the motor cortex, which is involved in planning and coordinating movement; the prefrontal cortex, which is responsible for higher-level cognitive functioning; and Broca’s area, which is essential for language production. The frontal brain lobe is the largest part of our brain. The frontal brain lobe is the center for planning, speech production, body movement control, as well as problem-solving.The medial frontal area is responsible for awareness and motivation. The frontal orbital area helps shape social behavior.
