How do heredity and inheritance relate to the data presented In these charts
Your risk is greatly raised if any of these relatives have had breast or ovarian cancer. However, until many of these “secondary” relatives have the disease.
What is role of inheritance in breast cancer?A woman's risk of breast cancer nearly doubles if she has a first-degree family (mother, sister, or daughter) who has the disease.
Her risk is nearly three times higher if she has two first-degree relatives. A woman's risk of developing breast cancer is considerably higher if her father or sibling had the disease.
Gene changes that are connected to breast cancer are typically acquired. Only the breast cancer cells experience acquired DNA alterations over time.
Therefore, Hereditary is Breast cancer and Inheritance is Getting Breast Cancer, basically it runs in the family inheriting.

In your own words, please explain how the process of meiosis leads to siblings that are not clones of each other.In your own words, please explain how the process of meiosis leads to siblings that are not clones of each other.
Explanation:
The process of cell division by which most of cells divide for growth is called mitosis.
In this process, each cell called mother cell divides to form two identical daughter cells. The daughter cells have the same number of chromosomes as mother cell. It helps in growth and repair of tissues in organisms.
Specific cells of reproductive organs or tissues in animals and plants divide to form gametes., which after fertilisation give rise to offspring.
They divide by a different process called MEIOSES.Which involves two consecutive divisions. When a cell divides by meiosis it produces four new cells instead of just two .
The new cells only have half the number of chromosomes than that of the mother cells.

C: CLAY,ORGANIC LAYER, GRANITE
D: GRANITE, ROCK, SOIL
soil, rock, organic layer
Explanation:
Permeability is the ability of a layer of rock to transmit fluid such as oil or water
The factors that affect the permeability of a rock layer includes the sizes of the rock particles, the ratio of the available voids to the solid mass of the rock, the presence of trapped air and the presence of organic matter
Rocks such as gravels, and sparingly cemented sands have high permeability
The most impermeable of the options are granite and clay which for granite has large particle mass and contain no voids while clay has very fine particles packed together with little room for water
Therefore, water moves easily between layers soil, rock, organic layer

Why is it necessary to reduce the number of chromosomes in gametes, but not in other cells
Answer:
The reduction of chromosomes in the gametes is necessary to make sexual reproduction possible, in which each parent contributes half of their chromosomes and in fertilization a cell with the complete amount of chromosomes is produced, the zygote.
Explanation:
The reduction of chromosomes to form gametes is done by meiosis, a reductive cell division. Sex cells or gametes are haploid cells, i.e. with half the chromosome charge, as each parent must contribute a gamete in the reproductive process.
The union of the parents' gametes is called fertilization and its product is the zygote, whose chromosome charge is complete or diploid.
For a diploid zygote to be formed, it is necessary for the sex cells or gametes to be haploid, or with half of the chromosomes of the species..
The genetic content built of proteins and nucleic acid found in the nucleus of cells are called chromosomes.
The reduction of the chromosome is essential for sexual reproduction.
In this sort of reproduction gametes from each parent fuse to form offspring.Each parent provides half the number of chromosomes (n) to form a complete offspring with the total set of chromosomes (2n).In the process of gamete formation chromosomes, get halved due to meiosis.The reproductive gametes from both the parent combine via fertilization and form the diploid offspring.Therefore for a diploid offspring to be formed the gametes need to be haploid.

What is unique about obtaining water from an artesian well?
O The water is heated by magma or hot rocks.
O The water is found in an impermeable layer.
O The water is under pressure naturally and no pump is needed.
O Amechanical pump must be installed to bring water to the surface.
Answer:
c-The water is under pressure naturally and no pump is needed.
Explanation:
Water from Artesian well is the water is under pressure naturally and no pump is needed.
What is Artesian well?A well from which water flows under natural pressure without the need for pumping is known as an artesian well.
It is excavated or drilled whenever a gently sinking, permeable rock layer (such as sandstone) collects water at a level higher than the ground surface at the well site.
Water goes down into the aquifer (water-bearing layer) at the outcrop, but is blocked from escaping by impermeable rock layers above and below it (such as shale).
Water is forced to the surface of a well drilled down into the aquifer by the weight of the water (hydrostatic pressure) the pressure for the continuous up flow is maintained by the continued penetration of water into the aquifer at the intake region.
The ability to collect water is what distinguishes artesian wells.
The water is under pressure naturally and no pump is needed.
Pumping water isn't essential because there isn't any pressure in the water.
Hence, the correct option is C.

Rachal Corporation produces and sells a single product whose selling price is $150.00 per unit and whose variable expense is $57.00 per unit. The company's monthly fixed expense is $381,300.
Required:
a. Assume the company's monthly target profit is $9,300. Determine the unit sales to attain that target profit. Show your work!
b. Assume the company's monthly target profit is $18,600. Determine the dollar sales to attain that target profit. Show your work!
Answer:a) if the company's monthly target profit is $9,300, 4,200 units sales is needed
b) if the company's monthly target profit is $18,600, 4,300 units sales is needed
Explanation:
Using The Contribution Margin Approach:
Contribution Margin = Sales expense - variable expense
=$150.00 - $57.00
=$93
Contribution Margin Ratio= Contribution Margin/ sales expense x 100
=93/150 x 100
= 62%
Assume the company's monthly target profit is $9,300.
A) Sales to attain the target profit = [(Fixed expenses + Target profit) ÷ Contribution Margin ratio]
= ($381,300. + $9,300) ÷ 0.62
$390,600 ÷ 0.62
= $630,000
No. of units to be sold =Sales to attain the target profit/ selling price
$630,000/$150.00
=4,200 units
Assume the company's monthly target profit is $18,600
B) Sales to attain the target profit = [(Fixed expenses + Target profit) ÷ Contribution Margin ratio]
= ($381,300. + $18,600 )÷ 0.62
$399,900 ÷ 0.62
= $645,000
No. of units to be sold =Sales to attain the target profit/ selling price
$645,000/$150.00
=4,300 units

It is known that complex carbohydrates provide more sustained energy over time than simple sugars such as sucrose. Complex carbohydrates are polysaccharides, which are long chains of smaller sugar molecules bonded together. Simple sugars are monosaccharides that contain only one molecule.
Why do complex carbohydrates provide more energy over time versus simple carbohydrates?
Answer:
Complex carbohydrates contain longer chains of sugar molecules than simple carbohydrates. The body converts these sugar molecules into glucose, which it uses for energy. As complex carbohydrates have longer chains, they take longer to break down and provide more lasting energy in the body than simple carbohydrates
Explanation:
Answer:
A.) Complex carbohydrates have more chemical bonds to break than simple sugars, which takes longer for the body to digest and provides more units of energy for the body to use.

O All cells come from pre-existing cells.
•All cells require water for survival.
•All living things are composed of cells.
•Cells are the basic unit of structure and function of living things.
Answer:
The unified cell theory states that: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells.
Therefore, B is the answer.
"All living cells require water for survival" is NOT a statement from the cell theory.
All cells require water for survival is not a statement from the cell theory.
What is cell theory?The cell theory is a fundamental principle in biology that states that all living organisms are composed of one or more cells and that the cell is the basic unit of life. The theory was first proposed by German scientists Matthias Schleiden and Theodor Schwann in 1839, and later refined by Rudolf Virchow in 1855. The three main principles of the cell theory are:
All living organisms are composed of one or more cells.The cell is the basic unit of life and structure for all living organisms.All cells come from pre-existing cells through the process of cell division.The cell theory is considered one of the most important and enduring concepts in biology, and it forms the foundation for understanding the structure and function of cells and the organization of life on Earth.
