A man who has cystic fibrosis married a healthy women. They produce 2 children who both have cystic fiber. What are the genotypes of the man and women? (use symbols to represent the alleles and which parent is which)
Answer:
The correct answer would be -
Father - both alleles are recessive for the gene - cc
Mother - carrier with the heterozygous condition - Cc
Explanation:
Cystic fibrosis is a recessive genetic disease that means it exhibits only if both copies of the gene mutated, If there is only one copy of the gene is mutated the person will be healthy however, he or she will be a carrier of the mutated gene.
Given: Father has cystic fibrosis which means he has two copies of the mutated gene - cc (c - recessive)
Female - she is healthy now there is two conditions possible
1. if the mother is healthy - CC (normal allele)
C C
c Cc Cc
c Cc Cc
All offspring are in the heterozygous condition that means they are healthy carriers which is not given in the question so women must be a carrier
2. Carrier mother - Cc
C c
c Cc cc
c Cc cc
Here 50% chances of having children with CF so it is possible as two offsprings have CF according to question
Thus, Father - both alleles are recessive for the gene - cc
Mother - carrier with the heterozygous condition - Cc
The twisted ladder shape of DNA
A.
triple helix
B.
helical ring
C.
double helix
D.
hexagonal ring
Answer:
C. Double helix
Explanation:
The twisted ladder shape that DNA has can also be called a double helix.
It is in the shape of a helix, which is similar to a 3D spiral shape.
It is called a double helix because DNA is made up of two DNA helix strands that are intertwined.
So, C is the correct answer.
Answer:
The answer is C. double helix.
Explanation:
DNA is constructed through two threads or strands winded around each other in the shape of a twisted ladder - hence one of the shape of a DNA's most prominent nicknames (that is, twisted ladder). Additionally, it is even more commonly known as a double helix. In fact, the term double helix was especially created to describe DNA!
Why are the terrestrial planets made up of rock and metal and the jovian planets made up of gas?
Answer: The terrestrial planets formed close to the Sun where temperatures were well suited for rock and metal to condense. The jovian planets formed outside what is called the frost line, where temperatures were low enough for ice condensation.

Two barometric pressure readings taken 12 hours apart in four North Carolina cities are shown in the table. City Air Pressure 1 Air Pressure 2 Jacksonville 1,095 millibars 1,070 millibars Asheville 946 millibars 1,090 millibars Raleigh 1,100 millibars 1,032 millibars Charlotte 1,068 millibars 923 millibars Which city is most likely having severe weather?
help pls
Millibars are a form of atmospheric pressure.
Hurricanes or severe storms usually have very low atmospheric pressure. So your answer would be 923 HPA (Hecto pascals) or as we call it millibars. 923 Millibars is the average atmospheric pressure for a cat 4 hurricane. So charlotte with 923 is your final answer!

A) Chloroplasts transform chemical energy into electromagnetic energy.
B) Mitochondria transform light energy into chemical energy.
C) Chloroplasts transform light energy into chemical energy.
D) Mitochondria transform chemical energy into electromagnetic energy.
Answer:
A) Chloroplasts transform light energy into chemical energy.
Explanation:
Chloroplasts are plastids, cellular organelles inherent in plant cells, which contain a green pigment, chlorophyll, by which they perform photosynthesis.
Photosynthesis is a process in which, with the help of chlorophyll, solar energy is converted into chemical energy in order to use that chemical energy (ATP) for the synthesis of organic matter from inorganic matter (CO2 and H2O).
Answer:
C. Chloroplasts transform light energy into chemical energy.

Explanation:
9. Halobacterium has a photosynthetic membrane that is colored purple. Its photosynthetic action spectrum is exactly complementary the action spectrum for green plants. What wavelengths of light do the Halobacterium photosynthetic pigments absorb
Answer:
Yellow-green
Explanation:
Let us remember that the colour that is transmitted is always complementary to the colour that is absorbed.
Hence, if a substance absorbs a particular colour, it will transit the colour complementary to that absorbed colour.
The complementary colour of yellow-green is purple hence yellow green light of wavelength 560 - 580 nm is absorbed.

describe the main difference between a bright field, compound light microscope and a dissecting microscope
Answer:
Please find the main difference in details between these two microscopes below
Explanation:
Compound microscopes and dissecting microscopes are two types of light microscopes. This means that both types of microscope uses light as a source of view. However, they are used for different purposes despite this similarity.
- The compound microscope is used to view the internal features of a small specimen by looking through it. This is due to the high magnifying power of its objective lenses (40x - 1000x).
- On the other hand, dissecting microscopes are used only to view the surface of a large specimen owing to its low magnifying power. It can be used to view a three dimensional object.
In the 1970s, public opinion favored cleaning up the environment. Since the 1980s, some members of Congress and industry leaders have fought against environmental laws that regulate the amount of pollution that can be added to the environment. Are they working in the best interests of the public or of corporations?
Answer:
They are working in the best interests of corporations
Explanation:
Corporations and industries are responsible for a large percentage of environmental pollution being witnessed in several regions of the world. The pollutions have negative consequences for the environment and the organisms living in it, including humans. Hence, formulating laws to regulate the amount of pollution that can be added to the environment is in the best interests of the public. Any person that fights against these laws is likely working in the interests of industries and corporations and not the public in its entirety.
Electricity, Force, Energy, Motion, and Light are concepts investigated in the study of ____.
Answer: physics
Explanation:
one of the earliest events that distinguish meiosis from mitosis occurs in prophase 1 and involves
Answer:
This question lacks options, options are:
A. Pairing of homologous chromosomes
B. Movement of chromosomes towards the metaphase plate
C. Condensation of chromosomes
D. Loss of the nuclear membrane
The correct answer is A. Pairing of homologous chromosomes
Explanation:
Mitosis and meiosis are two different forms of cell division in eukaryotic cells, those that have a nucleus.In meiosis in Prophase I: homologous chromosomes pair up and exchange genetic material by crossing over. In mitosis in Prophase I: genetic material begins to condense and form long, thin strands. The mitotic spindle is formed.During the cell cycle, the eukaryotic cell undergoes a series of changes that lead to the formation of new cells. Depending on the type of cell, it can divide by mitosis or meiosis.
How are precipitation and temperature different between the polar and tropical climate zones?
Answer:
The temperature is colder in the polar climate zones. Also, there is less precipitation in polar climate zones. Meanwhile,the temperature is warmer in the tropical climate zones. Also, there is more precipitation in tropical climate zones.
Explanation:
The earth is extremely diverse in its ecosystem. Different regions are called climate biomes to understand patterns of meteorology, biology, and natural phenomena.
The biggest difference between tropical and polar climates is the difference in temperature. The tropical climate is close to the equator and has more sun all year round than anywhere else on the planet, but the polar climate is the furthest from the equator and has the least sunlight and heat of any part of the world. This makes winters harsher and summers shorter in polar climates, but hotter virtually every day in tropical climates. Both climates are reminiscent of precipitation (such as tropical rains and polar snow), but both can be quite dry. Antarctica is said to be the largest desert in the world because there is little snow falling towards the center of the continent.
What are examples of tropical desserts?Tropical deserts, such as the Namib Desert in Africa, are so hot and dry that it is difficult to survive.
Thus it concludes that precipitation and temperature are different between the polar and tropical climate zones.

Choose the term that best matches the description given. Treatments that destroy or decrease the growth of a microbe infection in a patient ______ a. Disinfects b. Antiseptics c. Sterilization d. Antimicrobials e. Quarantine
Answer: The correct option is D (Antimicrobials).
Explanation:
Antimicrobial treatment is defined as therapies that are given to patients to either inhibit or kill the growth of microorganisms IN their body cells. The antimicrobial treatment can be grouped into two based on their mechanism of action. These includes:
--> Microbiocidal therapy: This type of treatment when given, kills the microorganisms in the cells of the patient.
--> Microbiostatic therapy: This type of treatment aims at inhibiting the growth of microorganisms when administered to a patient.
The antimicrobial drugs achieve their role usually through their different modes of action which includes:
--> cell wall inhibition
--> inhibition of cell membrane function
--> protein and nucleic acid synthesis inhibition.
Disinfects, antiseptic and sterilisation are all different ways of eliminating microorganisms but not used as invitro (within) treatment for patients. Therefore the term that best matches the description given is antimicrobials.

In an experimental study, the barnacle species Balanus was removed from rocks exposed at low tide. The barnacle species Chthamalus then established in the habitat where Balanus previously thrived. This provides evidence that:
Explanation:
There are two kinds of niches demonstrated by two barnacle species Balanus and Chthamalus where Balanus is being realized niche as it
is the actual habitat and this species interest with other species and other aspect affects the survival like competition and predation etc. Fundamental niche is demonstrated by Chthamalus as they can easily live and thrive in thehabitat and can multiply too and it will be still greater as opposed to realized.The right answer is, 'Chthamalus's basic niche is greater than its niche'
