Which conclusion is supported by the fact that the black-breed boar, with its quality meat, and the white-breed sow, with its quality fertility, are swine that are often matched for mating? Animals are often paired based on physical traits and personal compatibility. Strong reproductive capability is the most important trait in animal breeding. Selective breeding combines ideal traits of animals to replicate in offspring. Swine are the only agricultural animal species that are currently crossbred.
Answers
Answer:
Selective breeding combines ideal traits of animals to replicate in offspring
Explanation:
Selective breeding is the process which involves choosing parents with particular characteristics to breed together and produce offspring with more desirable characteristics. It is also known as artificial breeding and provides both plants and animals with greater variation and higher chances of survival. Selective breeding can be used to produce plants with bigger and tastier fruits and vegetables, crops with greater resistance to pests and diseases, and bigger animals that can be used for meat or milk production. The process of selective breeding is of great importance to the farmer today as it has brought about greater economic advantages.
In the instance of the black-breed boar and the white-breed sow being matched for mating, the reason is to combine these desirable traits in their offspring. The black-breed boar produces quality meat while the white-breed sow has quality fertility. Mating between these two breeds will produce offspring which has both traits of quality meat production as well as quality fertility.

Elements such as The lungs exchange gas to maintain homeostasis. In the alveoli of the lungs, oxygen and carbon dioxide are exchanged. This exchange occurs between the lungs and blood vessels (capillaries). The transport of oxygen to the blood does not require energy. The membranes of the alveoli are thin and moist and allow gasses to dissolve and be transported to and from the blood. When we breathe, a high concentration of oxygen enters the lungs and moves to the blood. Based on this scenario, is the transport of oxygen a result of osmosis, diffusion, or active transport?
Answers
Answer:
oxygen are among the few simple molecules that can cross the cell membrane by diffusion. And Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane. The oxygen molecules move, by diffusion, out of the capillaries and into the body cells. While oxygen moves from the capillaries and into body cells, carbon dioxide moves from the cells into the capillaries.

A student examines a thin section of an onion-root tip and records the number of cells that are in each stage of the cell cycle. She observes 93 cells in interphase, 15 cells in prophase, 4 cells in metaphase 6 cells in anaphase and 2 cells in telophase. If the complete cell cycle in an onion-root tip cell requires 24 hours, what is the average duration of each stage in cycle?
Answers
Answer:
given:
Total number of cells in all stages = 93+15+4+6+2 = 120
Total time = 24 hours.
solution:
Percentage of cells in interphase
= 93 * 100 / 120 = 77.5%
in prophase
=15 * 100 / 120 = 12.5%
in metaphase
= 4 * 100 / 120 = 3.33%
in Anaphase
= 6 * 100 / 120 = 5%
in telophase
= 2 * 100 / 120 = 1.66%
The percentage of cells present in various phases exhibits the time spend by each cell in that phase.
Total minutes
= 24*60 = 1440
Total minutes spent in interphase
= 77.5 * 1440
= 1116 minutes
in prophase =12.5 *1440
= 180 minutes
in metaphase = 3.33*1440
= 48 minutes
in Anaphase = 5*1440
= 72 minutes
in telophase = 1.66*1440
= 24 minutes

What is the main function of DNA?
The genetic information contained in the DNA is used by the nucleus to regulate all cellular functions, including growth and metabolism.
Today, DNA has three separate purposes: genetic, immunological, and structural, all of which differ greatly from one another and depend in different ways on the bases and the sugar phosphate backbone.
Genetic information is encoded in the nucleotide order along the backbone. Replication, information encoding, mutation/recombination, and gene expression are the four functions that DNA performs.
Therefore, DNA which is found in nucleus control a cellular activity.
