If Individual 3 has children with a woman that is heterozygous for the genetic disorder, what is the probability they will have an affected child?
If Individual 3 has children with a woman who is heterozygous for the genetic disorder, then the chance of producing genetically disordered offspring is 25% if the male is heterozygous and 0% if the male is not.
What is the genetic disorder?A recessive genetic disorder, such as cystic fibrosis, and an autosomal dominant disorder, such as Huntington's disease, are examples of genetic disorders caused by a gene that can express itself in either a dominant or recessive manner. For example, the disease is represented by the aa. If the male is heterozygous for diseases such as "Aa," then he will produce 25% "aa" type offspring when he crosses with the heterozygous female. When a man is purebred AA and crosses with a heterozygous female, then no offspring will be genetically infected.
Hence, if Individual 3 has children with a woman who is heterozygous for the genetic disorder, then the chance of producing genetically disordered offspring is 25% if the male is heterozygous and 0% if the male is not.

Which type of mutation is shown here?
Original: A T A C A C
Mutant : T T A C A C
A.translocation
B.non-disjunction
C.frameshift
D.point
Answer:
d
Explanation:
that is an example of a point mutation. A point mutation is a mutation that causes only one nucleotide to change and in the example adenine changes to thymine
hope this helps (:
The mutation shown here is point mutation.
What is mutation?"A changes/alteration in nitrogenous bases sequence of DNA that can results in changes in the genotype and phenotype of an organism is known as mutation."It occurs due to: deletion, insertion, translocation and inversion.During insertion, an extra nitrogenous bases are added to the DNA sequence.During deletion, a nitrogenous bases are removed from the DNA sequence.During inversion, the sequence of nitrogenous bases gets inverted in a DNA strand.In translocation, a sequence of one DNA strand breaks off and attaches to another DNA strand.What is point mutation?"A point mutation occurs in a genome when a single base pair is added, deleted or changed."Here, the sequence of original strand is A T A C A C and the sequence of mutant one's is T T A C A C. The base A is changed into base T.
Hence, the correct option is: D. Point mutation.

What is a body function that would contribute to BMR?
Breaking down a burger in the stomach
O Catching a Frisbee
O Heart beating
O Wrestling a Grizzly Bear
Answer:
Breaking down a burger in the stomach.
Explanation:
Basal metabolic rate (BMR) also known as resting metabolic rate (RMR) can be defined as the amount of calories that is required to keep the human body to function properly and perfectly at rest.
This ultimately implies that, basal metabolism is the minimal amount of calories or energy that is required by an individual for maintaining vital functions such as blood circulation, keeping the body warm and respiration while fasting or in a complete mental and physical rest.
Some of the factors that affects the basal metabolism rate (BMR) in humans are height, weight, age, starvation or fasting, thyroxine, fever, stress, malnutrition and growth.
Hence, breaking down a burger in the stomach is a body function that would contribute to BMR.
5 facts about the L.A. flood of 1938
I will give you all my points!
Answer:
1. The Los Angeles flood of 1938 was one of the largest floods in the history of Los Angeles, Orange, and Riverside Counties in southern California.
2. The flood was caused by two Pacific storms that swept across the Los Angeles Basin in February-March 1938 and generated almost one year's worth of precipitation in just a few days.
3. The Los Angeles, San Gabriel, and Santa Ana Rivers burst their banks, inundating much of the coastal plain, the San Fernando and San Gabriel Valleys, and the Inland Empire.
4. Flood control structures spared parts of Los Angeles County from destruction, while Orange and Riverside Counties experienced more damage.
5. It caused $78 million of damage ($1.42 billion in 2019 dollars),[2] making it one of the costliest natural disasters in Los Angeles' history.[3] In response to the floods, the U.S. Army Corps of Engineers and other agencies began to channelize local streams in concrete, and built many new flood control dams and debris basins
Explanation:
During fermentation, how do changes to a molecule of pyruvic acid to lactic acid or ethyl alchol contribute to
the formation of ATP?
Answer:
Some organisms, such as some bacteria, will undergo lactate fermentation. Two pyruvates are converted to two lactic acid molecules, which ionize to form lactate. In this process two NADH + H+ are converted to two NAD+. Our muscle cells can undergo this process when they are in oxygen debt.

What materials do motor neurons need to survive and how do they get those materials?
Answer:
Neurons are made up of three major parts: a cell body, or soma, which contains the nucleus of the cell and keeps the cell alive; a branching tree like fiber known as the dendrite, which collects information from other cells and sends the information to the soma; and a long, segmented fiber known as the axon, which transmits information away from the cell body toward other neurons or to the muscles and glands.

is chemical reaction between limestone and acid in groundwater responsible for its formation
Answer: Geysers are water that comes out of the ground spurting into the air, wetlands are self-explanatory, while volcanoes are full of magma, not of acid and limestone.The upper layers of soil above the groundwater contains carbon and limestone. The water being combined with carbon becomes acidic which erodes limestone this results in formation of sinkholes and caves.

What are the sex chromosomes? Explain how it is shown in male and female; and karyotyping
Answer:
Females have two X chromosomes, while males have one X and one Y chromosome. A picture of all 46 chromosomes in their pairs is called a karyotype. A normal female karyotype is written 46, XX, and a normal male karyotype is written 46, XY.
Explanation:
Sex chromosomes are chromosomes which are responsible for sex determination. These are the X and Y chromosomes. Females have two X chromosomes and males have one X and one Y chromosome in their sex cells/gametes. Karyotyping is the visualization of chromosomes after blocking the cells in mitosis and staining; this allows us to identify the size, shape, and number of chromosomes present in cells, which is significant because extra, missing, or abnormal chromosomes can cause developmental problems or issues with body functions.

What contribution to energy do carbohydrates make?
Answer:
Carbohydrates are the nutrients most frequently used as an energy source (containing 4kcal per gram), as they are fast-acting and turn into energy as soon as they are ingested. This energy powers the brain and body. The energy that powers the brain and body is generated when carbohydrates are broken down.

Some bacteria of the same species and genotype can reduce sulfur anaerobically for energy, depending on the environment. This
an example of...
A)growth and response
B)genotype mutation
C)phenotypic plasticity
D)inclusive fitness
Answer:
C) phenotypic plasticity
Explanation:
The ability of an organism to change phenotypically according to environmental conditions is known as Phenotypic plasticity.Organisms might adjust their morphology and physiology to a better performance in environmental heterogeneity.
Generalists species might present a higher magnitude of phenotypic plasticity than specialist species.
Sulfur-reduction bacteria are obligated anaerobic microorganisms, that are metabolically versatile. They might grow either as heterotrophs using organic molecules or as autotrophs using hydrogen and carbon dioxide.These bacteria are notoriously adaptable and might be found in many different environments (terrestrial and/or aquatics) where there is no oxygen due to aerobic decomposition of the organic matter.
They can be found in anoxic sulfuric environments. In the soil, in estuaries mud, in freshwater, in sewage systems, salty waters, thermal water, sulfur deposits, in oil and gas wells, and even in animals and insects intestine.
