Answer:
Groups and periods are two ways of categorizing elements in the periodic table. Periods are horizontal rows (across) the periodic table, while groups are vertical columns (down) the table. Atomic number increases as you move down a group or across a period.

Farmer Carroll breeds his black-colored dog and his golden-colored dog every spring to sell the puppies. Golden color is recessive to black. The most recent litter of puppies included 4 black and 4 golden. What most likely is the genotype of the black dog?
Answer:
Bb
Explanation:
If you use "b" to represent golden allele and "B" to represent the black allele, then crossing a Bb and bb dog will result in a 50/50 chance of they offspring being black or golden. Since half of the litter is black and the other half is golden, the black colored dog has a Bb genotype.
An allele is the alternative of the genes present for a character or a trait. The genotype of the black dog will be Bb.
What is a genotype?A genotype is a genetic information contained in a cell that passes from generation to generation.
The allele of golden-colored dog = b
The allele for black-colored dog = B
The genotype of the black and the golden litters are 1:1 or 50% each as 4 puppies are black and another 4 are golden.
If the parents having Bb and bb are crossed then only there is a chance that the 50% offspring will be black and golden. For an offspring to be 50% black the genotype of the parent must be heterozygous.
Therefore, the genotype of the black dog will be Bb.

Fisherman in a certain region have noticed a significant decrease in the biodiversity of fish species present in a local body of water. This has caused a decrease in the variety of fish available for consumers in the region. Which of the following changes has most likely caused this change in biodiversity?
A.
an increase in fish reproduction rates
B.
the introduction of an invasive species
C.
a decrease in water pollution
D.
a prolonged period of increased rainfall
Answer:
B
Explanation:
The introduction of an invasive species makes sense, because invasive species can wipe out mulitple native species leaving less resources for the native fish, and thus, decreasing biodiversity. A great real life example of this would be the Lionfish.

While dry cleaners are small businesses, they generate relatively large volumes of hazardous substances. EPA estimates the average dry cleaner generates 660 gallons of hazardous wastes a year. Unlike petroleum contamination which may break down over time by naturally - occurring bacteria in the environment, the chlorinated solvents that are used by dry cleaners are resistant to biodegradation. As a result, groundwater contamination from dry cleaners has a greater potential to migrate off-site which can be problematic since dry cleaners are often located within proximity to residential neighborhoods. Indeed, a 2002 Florida study found that dry cleaner contamination had migrated off-site at 57 percent of the contaminated sites. Due to these types of environmental hazards when commercial land is sold require a Phase 1 Environmental Assessment according to the Comprehensive Environmental Response, Compensation and Liability Act.
Why would the type of monitoring required as part Phase 1 Environmental Assessments be important if a dry cleaner was being sold?
Group of answer choices
This type of monitoring will allow the government to only sell land to businesses that have environmentally friendly practices.
The monitoring will allow the government to determine which type of business is better for the environment so dangerous businesses can be closed.
The monitoring will indicate any environmental damage done that should be remediated prior to selling the land.
The monitoring prevents the land from being resold to any dry cleaning businesses which can be damaging to the environment.
Answer:
This type of monitoring will allow the government to only sell land to businesses that have environmentally friendly practices.
Explanation:
This type of monitoring will allow the government to know about the businesses that causes pollution in the environment and the government is responsible to sell the land to those businesses that have used the methods which is environmentally friendly. The environmental friendly practices reduces the damage occur to the environment from human activities so the government must do monitoring of businesses.

What happen to the brain and the brain cavity?
Answer: OK so The ventricles of the brain are a communicating network of cavities filled with cerebrospinal fluid (CSF) and located within the brain parenchyma. The ventricular system is composed of 2 lateral ventricles, the third ventricle, the cerebral aqueduct, and the fourth ventricle (see the images below).Survival in untreated hydrocephalus is poor. Approximately, 50% of the affected patients die before three years of age and approximately 80% die before reaching adulthood. Treatment markedly improves the outcome for hydrocephalus not associated with tumors, with 89% and 95% survival in two case studies

What is the significance of crossing over?
Answer and Explanation:
Crossing over is the switching of genetic material (DNA), which occurs in Prophase 1.
This all happens in Meiosis, which is the process of the formation of sperm and egg cells.
The paired chromosomes from each parent align so that similar DNA sequences from the paired chromosomes cross over one another.

Answer:
Suface currents are mostly caused by the wind because it creates friction as it moves over the water. This friction then forces the water to move in a spiral pattern, creating gyres. In the northern hemisphere, gyres move clockwise; while in the southern hemisphere, they spin counterclockwise.

While volunteering at a hospital, Alex learns that there are several different human blood types and they are determined by alleles. For example, a person with an allele for type A blood and an allele for type B blood will have type AB blood. Alex asks a nurse if blood type A or B is dominant. What answer does the nurse give him?
Answer:
They are codominant
Explanation:
There are 3 different alleles: IA, IB and i - IA and IB are codominants, i is recessive. Codominance means neither allele can mask the expression of the other and both alleles A and B are expressed in the blood type.
Blood type A and Blood type B both are dominant if allele A or allele B present with the O allele, however, they show codominance if they present together.
The human blood group system is known as the ABO blood group system that exhibits codominance. Following are the characteristics of this blood group system:
The system consists of three alleles A, B, and O.Both A and B are dominant in relation to O, and therefore blood group A or B can have the genotype AA or AO or BB or BO respectively.If both A and B are present together then they show codominance and have the genotype AB.Thus, the correct answer would be - both A and B are dominant if allele A or allele B present with the O allele, however, they show codominance if they present together.
