anyone know the correct choice to the question?
Answer:
person 1 in row 3's genotype AA or Aa
Explanation:
the trait is recessive (given) which means in order to have it, you must obtain both alleles. in the pedigree, shaded shapes indicate people who have the trait, but person 1 in row 3 is not shaded so their genotype must be AA (dominant) or Aa (dominant leading) and their phenotype would not express the trait, because the dominant allele will "take over"
13. When each allele in a heterozygous genotype influences the phenotype and

Polygenic Trait
Explanation:
A taits phenotype is influenced by more than one gene. Traits that display a continuous distribution, such as height or skin color, are polygenic.
Which of the following describes how metamorphic rock forms?
A
Tectonic plate boundaries break apart an existing parent rock.
B
An igneous rock deep in the Earth is exposed to hot material.
C
Molten rock solidifies and hardens on top of the Earth’s crust.
D
A parent rock is baked and melted into liquid rock in the Earth.
An igneous rock deep in the Earth is exposed to high heat, high pressure, and hot mineral-rich fluids, by this process metamorphic rock forms, hence option B is correct.
What is a metamorphic rock?Metamorphic rocks are produced when rocks are exposed to high heat, and pressure, hot mineral-rich fluids, or maybe some combination of these factors, all these conditions are found deep on Earth.
In the deep of Earth, if an igneous rock deep in the Earth is exposed to hot material, this result forms a metamorphic rock.
This is also a result when rocks change their original shape and identity due to high heat or pressure, this pressure is only found deeper in the Earth.
Therefore, if an igneous rock deep in the Earth is exposed to hot material, it results in metamorphic rock.

During sexual reproduction, each parent contributes
A
a double helix of chromosomes.
B
one strand of chromosomes, or half of the new organism's DNA.
C
a dominant gene and a recessive gene.
D
multiple mutated cells.
Answer:
[tex]\boxed {\boxed {\sf B. \ One \ strand \ of \ chromosomes \ or \ half \ of \ the \ new \ organism's \ DNA}}[/tex]
Explanation:
Sexual reproduction involves gametes. These are sex cells (sperm for males and eggs/ovum for females).
These sex cells are formed during meiosis. During this process, two rounds of cellular division occur, so there are four resulting haploid cells. Haploid means they contain half of the genetic information.
These cells are haploid because during fertilization, a sperm and egg fuse to form a zygote. Each parent contributes half of the DNA to create one complete set of DNA.
Therefore, the best answer choice is B. one strand of new chromosomes or half of the new organism's DNA.

A dietician is studying the data collected in an experiment performed by a colleague. The experiment was designed to test the hypothesis that abnormally high blood urea nitrogen (BUN) levels are directly related to increased protein. Nitrogen in the blood in the form of urea, called blood urea nitrogen (BUN), is a toxic by-product of the breakdown of proteins and is filtered out of the blood by the kidneys. The results of the colleague's investigation are given below.

* Value suggested is for a healthy 154 pound man who regularly exercises.
** mg/dL means milligrams of BUN per deciliter of blood
Which of the following best describes the dietician's criticism of this experiment, and how does she recommend improving it?
The test subjects may have also consumed carbohydrates and fats during the 30-day trial, so the amount of carbohydrates and fats in the test subjects' diets should be limited.
Since BUN is filtered by the kidneys, reduced kidney function could also explain the BUN levels in the test subjects. Therefore, the kidney health should be measured and only test subjects with fully functioning kidneys should be used.
Since the recommended daily protein intake is 105 g/day for a 154-pound man, the test subjects should all be men of the same weight, and they should all consume about 105 g/day of protein during the 30-day trial.
Since abnormally high BUN levels result from increased protein intake, and high BUN levels can be a sign of kidney failure, the test subjects' protein intake should be limited to 105 g/day and below.
Answer: ANSWER IS B
Explanation:
Since BUN is filtered by the kidneys, reduced kidney function could also explain the BUN levels in the test subjects. Therefore, the kidney health should be measured and only test subjects with fully functioning kidneys should be used.

Entre los hijos de esta pareja hay algunos que muestran Rh+ y Rh-.
Si la madre es Rh-, entonces su genotipo es rr y solo tiene alelos recesivos r para pasar a la progenie.
Sabemos que el padre es Rh+, lo que indica que en su genotipo hay al menos un alelo dominante R. Puesto que la mitad de sus hijos tiene factor Rh-, podemos asumir que el hombre es heterocigoto para el tipo de sangre (Rr). De los contrario, de ser homocigoto dominante, toda la descendencia seria Rh+. El padre le hereda a la mitad de los hijos el alelo R y a la otra mitad el alelo r.

The full-length (i.e., containing the entire protein-coding region) cDNA for a specific eukaryotic gene in humans is 1500 nucleotides long. You screen a pig genomic library with this cDNA and isolate two genomic clones of different lengths. Both clones are sequenced and found to be 1900 and 2100 nucleotides long from start codon to stop codon. Screening of genomic libraries of several other organisms reveals that all of them contain only one genomic clone -- pigs seem to be the exception to the rule here. What evolutionary events might have led to the presence of two genomic clones in pigs, and the discrepancies in their length compared to the cDNA probe
Answer:
In pigs, this gene suffered duplication and then paralogous genes diverged by accumulating mutations during evolution
Explanation:
Paralogous genes can be defined as evolutionarily related genes that emerged by duplication in a common ancestor of the two species being compared. Gene duplication is one of the most important mechanisms of genome evolution by which paralogous genes arise and acquire novel functions. After gene duplication, one of the two functional gene copies is prone to accumulate mutations because the organism has two genetic sequences to produce the same protein encoded by this gene. In consequence, it is expected that the cDNAs obtained from these genetic sequences show differences in nucleotide length.

Answer:
Golgi body
Explanation:
A cell organelle is a structure found in a cell that plays a specific role or function. Some of the cell organelles in living cells include nucleus, mitochondria, chloroplast etc. Ideally, the NUCLEUS, which is the organelle that directs the processes of other organelles contain the genetic material called DNA, which is a type of nucleic acid.
However, some organelles like mitochondria, ribosome and chloroplast also contains nucleic acid.
- Mitochondria contains it's own DNA nucleic acid.
- Chloroplast, also contains its own DNA nucleic acid.
- Ribosomes contain RNA (ribosomal RNA and transfer RNA).
PLS HELP ASAP Select the word that means how easily water can move through a substance. Lesson 2.03 o particles permeability porosity
Answer:
permeability
Explanation:
dictionary definition: the state/quality of a material or membrane that causes it to allow liquids or gases to pass through it
in biology we use this term to describe the cell membrane, it is "semi-permeable" because it allows certain gasses and molecules to pass through
The water can easily move through a substance and it is called permeability. Hence, option B is correct.
What is permeability?The ability of molecules to pass through a biological membrane or barrier is known as biological permeability. Because cell membranes are selectively impermeable, substances cannot pass through the barrier without consideration. Some of the characteristics that affect permeability include polarity, hydrophobicity, charge, size, and shape.
The metabolic activities, survival, and potential use of the cell in both biotechnological applications and physiological systems are all greatly impacted by the cell membrane permeability, which controls the rate of solute transport into and out of the cell.
The water can easily move through a substance when the substance is permeable. Hence, option B is correct.

Explain how germinating peas use cellular respiration to obtain energy stored within their endosperm?
Answer:
Explanation:
Through aerobic respiration in the presence of oxygen they produce ATP. Explanation: Food reserves in the seeds will be hydrolyzed by the enzyme alpha amylase. ... These glucose molecules will enter into the glycolysis, TCA cycle and electron transport chain to produce ATPs.
Germinating peas use cellular respiration to obtain energy stored within their endosperm in the following way:
The endosperm is the tissue that has the function of accumulating the seminal reserves, which are the nutritional substances for the embryo, supplying all the energy necessary for it to begin its evolution.
During dormancy, the seed "waits" until conditions are correct and then germination begins.Germinating peas need to use stored energy reserves to form proteins, divide and maintain homeostasis (stable internal environment) and for this they carry out cellular respiration.The process begins by absorbing water and releasing a hormone called gibberellic acid, in turn, this substance is absorbed by the cells to form certain enzymes that will change the endosperm into sugar.Cells oxidize glucose (sugar) for energy, often this energy is used to convert ADP and phosphate into ATP, that is, the energy extracted from the sugar is stored by using it to synthesize the ATP molecule.This energy is used for germinating peas to actively divide and to maintain themselves.Therefore, we can conclude that germinating peas extract energy from endosperm into sugar through cellular respiration to create proteins, divide, stay alive and grow.

What is Northern Hemisphere?On June 21st we have the summer solstice in the Northern Hemisphere. This is the longest day of the year in the Northern Hemisphere and officially it marks the beginning of the summer. On this date, the sun gets the furthest north during sunset and sunrise on the Northern Hemisphere.
This is the case because that is when the Northern Hemisphere is the most tilted and exposed to the sunlight. Basically, the further north the Sun appears on the sky in the Northern Hemisphere, the more sunlight there will be and the higher the temperatures will be as well.
The Sun rises north of due east and sets north of due west.The Sun rises south of due east and sets south of due west.The Sun rises north of due east and sets south of due west.
