(c) What is the conditional probability that a fish weighs more than 7 kg given that they weigh more than 6 kg according to your estimated pdf?
Answers
a) Given that they weigh more than 6 kg The empirical conditional probability that a fish weighs more than 7 kg is:
P(x>7 | x>6) = P(x>7 and x>6)/P(x>6)= P(x>7)/P(x>6) = 1/2. Therefore, the empirical conditional probability that a fish weighs more than 7 kg given that they weigh more than 6 kg is 1/2.b) The estimate of the pdf of the fish weight using kernel density estimation with a rectangular kernel of width 2 is plotted below
c) Given that they weigh more than 6 kg The conditional probability that a fish weighs more than 7 kg according to the estimated pdf is:
P(x>7 | x>6) = P(x>7 and x>6)/P(x>6)= P(x>7)/P(x>6) = 0.198/0.419 = 0.472.

Answers
Answer:
The correct option is A (The release of human chorionic gonadotropin (hCG) by the developing placenta AND the production of estrogen and progesterone by the placental tissues).
Explanation:
The developing placenta release Human chorionic gonadotropin (hCG) during pregnancy. What this hormone does is tell the body (corpus luteum) to produce progesterone to maintain the pregnancy. The presence of Human chorionic gonadotropin is a sign of pregnancy, meaning successful fertilization had happened, and implantation of the embryo had occurred too, preventing another cycle of menstruation.
The successful development of a mature, full-term fetus also depends on estrogen which during pregnancy aids the formation of blood vessels and also aids fetal maturation. While progesterone is a hormone when released during pregnancy helps maintain a healthy pregnancy.

Explanation:
For a recessive gene to affect the child they must inherit two recessive alleles because if a dominant allele is inherited than the dominant trait will be the one that is expressed in the child. The only way to get two recessive alleles is to inherit one from both parents so the father must also carry the recessive allele. This means A must be the correct answer.
Imagine that you are standing in a pharmacy comparing the Supplement Facts panels on the labels of two supplement bottles, one a "complete multivitamin" product and the other marked "highpotency vitamins." a) What major differences in terms of nutrient inclusion and doses might you find between these two products? b) What differences in risk would you anticipate? c) If you were asked to pick one of these products for an elderly person whose appetite is diminisher which would you choose? Give your justification.
Answers
When comparing a "complete multivitamin" product to a "high-potency vitamins" product, several major differences in terms of nutrient inclusion and doses may be observed.
The "complete multivitamin" product is likely to offer a broader range of essential vitamins and minerals, providing a balanced combination of nutrients such as A, B complex, C, D, E, and K, along with minerals like calcium, magnesium, and zinc. On the other hand, the "high-potency vitamins" product may focus on higher doses of specific vitamins or a narrower range of nutrients, potentially targeting deficiencies or increased nutrient needs.
The doses in the complete multivitamin would typically align with recommended daily allowances, while the high-potency vitamins may exceed these levels. Consequently, the risk associated with the high-potency vitamins is higher, as excessive doses of certain nutrients can lead to toxicity or interactions with medications .
For an elderly person with a diminished appetite, the complete multivitamin would be the preferred choice due to its comprehensive nutrient coverage, balanced doses, and potential to compensate for dietary limitations. Consulting a healthcare professional is still advisable to consider individual needs and health conditions.

Answers
The right answer is Growing.
Mitosis is the cell division that allows an equal distribution of genetic information from an initial mother cell to two daughter cells while retaining the karyotype over the cell generations.
Mitosis will ensure - sometimes unfortunately - the good fulfillment of several phenomena:
1. embryonic development,
2. the general growth of organisms from birth to adult size,
3. the continued growth of certain organisms and / or organs; for example, trees, hair, teeth in ruminants, nails, ...
4. to renew dead cells; for example skin cells, red blood cells, ...
5. to ensure healing,
6. to preserve cellular identity during the development and renewal of cells belonging to the same organs, tissues, ...
7. As a result of disorders: cancers
An example of mitosis at work is growth. Therefore, option (B) is correct.
What is mitosis?Mitosis is the process of cell division where one cell divides into two identical daughter cells. Growth involves an increase in the number of cells and therefore, mitosis is essential for the growth of living organisms. During mitosis, the cell's nucleus divides into two identical nuclei, and then the cell splits into two daughter cells, each with a complete set of genetic material.
This process is essential for tissue repair, renewal, and growth in multicellular organisms. While photosynthesis and the uptake of carbon dioxide are important processes that occur in plant cells, they do not directly involve mitosis. Leaf turning yellow is an example of the aging process and does not involve mitosis.

The given statement is True. The Grossman model of Health Economics states that if there is an invention of a new medicine or drug which can slow down the aging process but cannot prevent it completely, then the demand for junk food like jelly donuts, french fries, and physical activity would decline.
However, sudden events like heart attacks or accidents like being hit by a bus may still occur. The Grossman model of health capital implies that the demand for unhealthy activities (such as smoking, drinking, etc.) increases with a decrease in an individual's health capital. An increase in the demand for healthy goods, such as medical checkups, healthy food, and a clean environment, can raise an individual's health capital.
Therefore, if a drug is invented that can slow down the aging process, the demand for unhealthy food items like jelly donuts, French fries would fall and physical activity would also be minimized due to the slowdown in the aging process. Hence, the given statement is True.

The Golgi apparatus and the endoplasmic reticulum produceproteins that are then sent outside the cell.D. The endoplasmic reticulum produces usable energy that the Golgiapparatus uses to make proteins.
Answers
Cell Biology: Parts of the cell. Organelles.
The endoplasmic reticulum is an organelle found just outside the nucleus that is made of several interconnected cisternae, which membranes are continuous with the outer nuclear membrane.
It has two sections: the rough endoplasmic reticulum, which has ribosomes on its surface, and the smooth endoplasmic reticulum.
Basically, the endoplasmic reticulum synthetizes proteins and membrane lipids, and then sends them to the place that needs them.
In turn, the Golgi body or Golgi complex is a different organelle that is also made of cisternae, and where the proteins sent from the endoplasmatic reticulum are processed and modified before reaching their final destination.
This means the correct answer would be B. The Golgi apparatus receives proteins from the endoplasmic reticulum that it can modify or store for later use.

What is the benefit to a cell when atp transfers a phosphate group to a protein?
Answers
A tremendous quantity of energy is released when an enzyme removes a phosphate group from ATP to create ADP. This energy is needed by the cell for several metabolic activities as well as the creation of macromolecules like proteins.
The phosphate groups that connect via phosphodiester linkages make ATP a great energy storage molecule to serve as "money". These electronegative charges that are connected with the bonds act as a repulsive force on the phosphate groups, making the bonds high energy.
By transferring a phosphate group to another molecule, ATP is able to fuel cellular operations (a process called phosphorylation). The coupling of the release of energy from ATP to the cellular processes that need energy is carried out by specialized enzymes.

Correlation between Mendels factors observed from the garden peas experimentation.
Answers
Mendelian inheritance was discovered when Gregor Mendel cross two pure breeds of peas. One is a pure breed of a purple pea plant and the other is a pure breed of a white pea plant. The result of the experiment is a hybrid offspring with violet flowers. The hybrid offspring is cross with each other and produce violet and white flowers.
For Mendel, it gave him the idea that there are "factors" affecting the inheritance of traits. These "factors" are now known as the genes, which are pairs of alleles that can have three genotypes: AA (homozygous dominant), aa (homozygous recessive), and Aa (heterozygous).
ANSWER:
In Mendel's experiment, the pure purple pea plant is homozygous dominant (PP) and the pure white pea plant is a homozygous recessive (pp). When they are crossed, the offspring become heterozygous/hybrid (Pp). Since the purple flower is dominant over the white flower based on their genotypes, the offspring will manifest a purple flower instead of a white flower.
But when two hybrid offspring are crossed, the produced offspring will either be purple or white. Thus, the "factors" can either be dominant or recessive.
Mendel carefully sorted the progeny derived from the parent plants based on the characteristics and counted the number that inherit each character.
Mendel studied inheritance in peas (Pisum sativum). He chose peas because they had been used for similar studies, are easy to grow and are biennial plants, and can be sown each year. Pea flowers contain both male and female parts, called stamen and stigma, and usually self-pollinate.
Mendelian factors are simply genes. Mendel while experimenting on the inheritance of traits (characteristics), used the term factors for the units that code for these traits. Later, these factors were given the term genes.
The main reason for their success of Mendel was that he took one character at one time in his experiments on hybridization. So it was easy. Other scientists also performed cross-hybridization for many characters, this made the experiments complex and they could not accurately explain the results.
Mendel observed seven different characteristics in the pea plants, and each of these characteristics had two forms. The characteristics included height (tall or short), pod shape (inflated or constricted), seed shape (smooth or wrinkled), pea color (green or yellow), and so on.
