The chromosome pairings which would represent a normal female duck have ZW. Birds show female heterogeneity. Thus, the correct option is C.
What is the sex determination of birds?Sex-determination system is a biological system which determines the development of sexual characteristics in a living organism. The sex determination system is of two types which include male heterogeneity and female heterogeneity.
The system of sex determination in birds is of female heterogeneity. In birds, the sex of birds is determined by the inheritance of the sex chromosomes. Female birds have the heterogametic sex chromosomes ZW, whereas male birds have the homogametic sex chromosomes ZZ. This sex-determining system is highly conserved in the birds, which include nearly ten thousand different species.
Therefore, the correct option is C.

What is the role of ATP in the process of active transport?
A- It provides the energy that cells need to move molecules against a concentration gradient.
B- It lengthens the fatty acid chains in the cell membrane.
С- It weakens the cell membrane, allowing molecules to pass through more easily.
D- It provides the energy to transport the cell in its environment.
Answer:
A
Explanation:
It provides energy to move molecules against the concentration gradient.
The role of ATP in the process of active transport is it provides the energy that cells need to move molecules against a concentration gradient. The correct option is A.
What is active transport?Active transport occurs when a molecule moves against the concentration gradient from an area of lower concentration to a region of greater concentration. Because active transport involves moving biochemicals from low-concentration locations to high-concentration areas, it requires chemical energy.
The movement of macromolecules like proteins and lipids into and out of the cell depends heavily on ATP. The energy needed for active transport mechanisms to move such molecules over a concentration gradient is provided by the hydrolysis of ATP.
Therefore, the correct option is A. It provides the energy that cells need to move molecules against a concentration gradient.

What are some of the problems with forensic evidence and its use in the
courtroom?
Identify at least three problems and write at least one paragraph for
each of the problems.
Answer:
- Not enough evidence
Sometimes there isn't enough evidence in a case to state fully what happened which can result into false accusation. It can also make the jury become confused and struggle to find whos the right murder due to the lack of evidence.
- misinterpreted evidence
If a forensic scientist looks at a piece of evidence with the wrong theory they might try to prove their theory by trying to get proof out of it which can cuse a domino effect to where the wrong person can be accused of the wrong thing.
- false evidence
The evidence may be planted and the forensic science can look at it the wrong way similar to misinterpreted evidence. usually forensic scientist can see that it has been planted but when they figure that it has then its even harder to look for the real evidence. and it would take a longer process. And if they present the false evidence in court it may take a bad turn.

37. Which of the following shows the correct relationship between monomers and polymers?
O nucleotides combine to form proteins
glycerol and fatty acids combine to form lipids
amino acids combine to form nucleic acids
O polysaccharides combine to form carbohydrates
Answer:
The correct answer is the second option - glycerol and fatty acids combine to form lipids.
Explanation:
Lipids are a polymer or macromolecule, and the smaller pieces, or monomers, that make up lipids are glycerol and fatty acids.
Option 1 is incorrect because nucleotides are the monomer for nucleic acids, not proteins.
Option 3 is incorrect because amino acids combine to form proteins, not nucleic acids.
Option 4 is incorrect because polysaccharides are polymers (the monomer for carbohydrates is monosaccharides).

nem A graph showing the five major extinctions throughout Earth's history is shown here. Although there have been periods of major extinction, the number of species on Earth, until very recently, is the highest it has ever been. Which statement(s) below accurately construct explanations that explain the diversity of species on Earth after mass extinctions? You may select all that apply. click 2
A) Increasing human populations breed new species to fill the role of extinct ones.
B) Speciation causes the divergence of populations into new species that increase biodiversity.
The biodiversity of life on Earth must remain equal, so new species form after an extinction.
D) After extinctions, there are periods of adaptive radiation where species fill vacated niches.
E) Shifting tectonic plates creates geographic isolation of populations that can diverge into new species.
Answer: B, D and E
Explanation:

Extreme temperature variations, fluctuating sea levels, and catastrophic, one-time occurrences like an asteroid striking Earth or a large volcano erupting in the past have all contributed to mass extinctions.
What is extinction?Extinction is defined as the loss of a species or a group of species as a result of environmental factors or evolutionary changes in individual species. There is a continual loss of species from Earth, and the rates have changed over time. IUCN Red List predicts that 25% of mammals are in danger of going extinct. Extinction is, in a sense, natural.
Populations divide into new species as a result of speciation, which boosts biodiversity. There are times of adaptive radiation following extinctions, during which time new species fill empty niches. Geographic isolation caused by shifting tectonic plates allows populations to divide into new species. The Permian-Triassic extinction, sometimes known as the "Great Dying," occurred around 252 million years ago.
Thus, extreme temperature variations, fluctuating sea levels, and catastrophic, one-time occurrences like an asteroid striking Earth or a large volcano erupting in the past have all contributed to mass extinctions.

Answer:
Yellowstone Hot Spot-North American Plate
Explanation:
Yellowstone Hot Spot-North American Plate is correctly matched to its overlying tectonic plate.
What are the functions of tectonic plates?Plate tectonics is the generally accepted scientific theory that considers the Earth's lithosphere to comprise a number of large tectonic plates which have been slowly moving since about 3.4 billion years ago.
There are seven major plates: African, Antarctic, Eurasian, Indo-Australian, North American, Pacific and South American.
The theory of plate tectonics revolutionized the earth sciences by explaining how the movement of geologic plates causes mountain building, volcanoes, and earthquakes.

Kwashiorkor is a form of malnutrition caused by a lack of protein in the diet, most often seen in regions experiencing famine (hunger). Explain why this lack of protein is especially harmful for children.
Answer:
Explanation:
Proteins are macromolecules that are important in the development and repair of bones and tissues. Since good sources of proteins are made up of essential amino acids, they contribute greatly to the well being of children based on the roles of these essential amino acids.
When children do not have this protein there diet, they could have stunted growth and weak bones (due to absence of protein for bone and tissue development), fatigue (absence of protein for development of muscle thus not enough glycogen is stored in the muscle cells), slowed/stunted growth (absence of proteins for the development of bones and tissues) and this children also have reduced immunity because of the absence of proteins which releases amino acid for immune/antibody formation.
