O A. Feeder operations raise hogs throughout their lifetime, farrow-to-finish operations raise young hogs, and finisher operations raise older hogs
O B. Feeder operations raise hogs throughout their lifetime, finisher operations raise young hogs, and farrow-to-finish operations raise older hogs
O C. Finisher operations raise hogs throughout their lifetime, feeder operations raise young hogs, and farrow-to-finish operations raise older hogs.
O D. Farrow-to-finish operations raise hogs throughout their lifetime, feeder operations raise young hogs, and finisher operations raise older hogs
Answer:
D. Farrow-to-finish operations raise hogs throughout their lifetime, feeder operations raise young hogs, and finisher operations raise older hogs
Explanation:
Hog farms operate in three different categories:
Farrow-to-finish: This involves breeding sows to produce offspring. The offspring's are then fed until they are have reached the size for slaughter. The entire process takes throughout the hogs lifetime.
Feeder operations: This involves breeding sows and then selling their piglets to other farmers who will then raise them for till they are matured for slaughters. This process is just to raise young hogs.
Finisher operations: This involves buying piglets from other farmers and then raising them until they are matured for slaughter. This finisher operations raise older hogs

c. Transcription of one DNA strand results in mRNA, which is a complementary copy of the information in the DNA.
Answer:
Explanation:
c. Transcription of one DNA strand results in mRNA, which is a complementary copy of the information in the DNA.
a. The mRNA leaves the nucleus and goes to a ribosome open choices for ranking.
b. The building blocks of proteins, are carried to the ribosome by tRNAsAmino acids.
The process of deoxyribonucleic acod starts with replication to transcription and translation.
Replication involves the formation of a complementary base from a old or template DNA Strand this then serve as a template for transcription.
transcription involves the coping of information on the DNA to an intermediate mRNA ( messanger ribonucleic acid) in the nucleus which then move from the nucleus to ribosome in the cytoplasm where translation occurs.
Translation is the conversion of the information on the mRNA to an amino acid with the help of enzyme transferse ribonucleic acid(tRNA).
Hence the arrangement is from C ---- A-----B.

You have the following consumable items that you do not want spoiled by the action of microorganisms, but you have space in your refrigerator for only one. You have already opened each and consumed some. Which one of these is most likely to spoil fastest and should therefore be placed in the fridge?
A. Bread Flavored syrup (contains water, high sugar concentration, flavors, e.g., used to flavor coffee and drinks)
B. Apple juice 80 proof liquor (contains water, 40% ethanol, flavors)
C. Mineral water (contains water, minerals)
Answer:
Bread Flavored syrup (contains water, high sugar concentration, flavors, e.g., used to flavor coffee and drinks)
Explanation:
Food spoilage refers to a situation in which food is no longer fit for consumption due to the action of certain microorganisms on the food. Hence, microorganisms cause the spoilage of food and beverages.
The rate of action of microorganisms on different beverages depends mostly on the content of the beverages.
Yeasts are often responsible for the spoilage of beverages with high sugar content and these tend to spoil faster than other beverages.

1.The illustration below shows that sexual reproduction involving two parent pea plants resulted in the production of four offspring.
A. All four offspring received all of their genetic information only from Parent 1 and are therefore identical to that parent
B. All four offspring received all of their genetic information only from Parent 2 and are therefore identical to that parent.
C. All four offspring are genetically unique and did not receive any of their genetic information from either parent.
D. Each of the offspring is genetically unique and received some of its genetic information from each parent, so each has some traits in common with each parent.
Answer:
C
Explanation:
Because of the x and y chromosomes and they split apart and that's how you get 4 offspring.
The fusion of two different gametes leads to the formation of new offspring is called reproduction. There are two types of reproduction that is sexual and sexual.
The correct option is A
The branch of biology which deals with the study of genes is called genetics. there are two types of alleles that give all the character to the phenotypes. The dominant allele is the allele that suppresses the recessive allele and shows its effect.
In question, the F1 generation shows only one type of character which belongs to parent 1 because that is the dominant allele.
Hence, the correct option is A that is all four offspring received all of their genetic information only from Parent 1 and are therefore identical to that parent

The type of weathering seen in the pictures is mechanical weathering.
Weathering is the process by which rocks, minerals, and other geological materials are broken down and altered over time by various physical, chemical, and biological processes. It is a fundamental part of the Earth's surface dynamics and plays a significant role in shaping landscapes.
Mechanical weathering involves the physical breakdown of rocks into smaller fragments without changing their chemical composition. It increases the surface area of rocks, making them more susceptible to further weathering.

Why are most genes inhibited in an average animal cell
Answer:
Most genes must be turned off because cells play specific functions, thereby only a limited number of genes must be expressed in each cell type in order to produce proteins required in the cell
Explanation:
Gener regulation is a critical molecular mechanism required for normal cell functioning. In consequence, genes are turned on and off depending on the cell type. For example, in the brain, cells that will be differentiated into neurons will be expressed, while genes involved in the differentiation of undifferentiated myoblasts into muscle cells will be turned off. Thus, genes are switched off in order to produce only those specific proteins which are required for each cell during specific developmental programs and functions carried out by each cell type.

the process of taking gaseous carbon dioxide or oxygen by leaves is termed
Answer:
photosynthesis
as in the process of photosynthesis plants take in carbon dioxide and give out oxygen.
hope it helps you
please mark me as brainlist
The process of taking gaseous carbon dioxide or oxygen by leaves is termed peristomal diffusion or diffusion through stomata present on leaves.
Plants take up carbon dioxide or oxygen from the air through their leaves as they have several stomata on their surface. The small holes or openings in the underside of the leaf are called stomata.
Diffusion through stomata also helps oxygen, produced in photosynthesis, to leave the leaf.The diffusion of gaseous carbon dioxide or oxygen is proportional to the concentration difference between the atmosphere and leaves.The loss of water vapor in transpiration also occurs through stomata.peristomal diffusion or diffusion through the leaves allows the gaseous exchange.Thus, the correct answer is - peristomal diffusion or diffusion through stomata present on leaves.

18. How has the use of herbicides affected agricultural productivity?
O A. Fewer pesticides are needed because of parasitoids.
OB. Fewer people are needed to weed because of herbicides.
O C. Fewer crops are produced because of herbicides.
O D. Fewer crops are organic because of the use of Bt toxin.
O Mark for review (Will be highlighted on the review page)
Answer:
B. Fewer people are needed to weed because of herbicides.
Explanation:
Herbicides are chemical substances specifically used to control the widespread growth of weeds i.e unwanted plants. Using herbicides has been useful in eradicating the weeds that pose a great threat to agricultural productivity.
Since chemical control (herbicides) has proven to be a faster and effective method, fewer people are needed to involve in the physical control of weeds i.e. weeding. Hence, the use of herbicides has affected agricultural productivity by helping to reduce the amount of laborers.
Use complete sentences to explain how the mass of hydrogen is conserved during cellular respiration.
Answer:
The mass of hydrogen is conserved during cellular respiration as it follows the Law of Conservation of Matter. This shows that hydrogen has been conserved throughout the entire process (H representing Hydrogen) as the product has the same amount of hydrogen as the reactants.
The AMOUNT of carbon-dioxide atoms released by respiration are EXACTLY EQUAL to the atoms of these materials contained in the oxygen and carbon converted. In this way respiration has conserved the mass or material and in this way followed the law of conservation of mass.
