Long chains of amino acids connected by amide bonds form the building blocks of peptides and proteins, which are macromolecules. A peptide's or protein's primary amino acid sequence within its structure determines both its identification and its purpose.
What are macromolecules' primary uses?Macromolecules are enormous molecules that fill a cell and give it vital life-sustaining functions. For instance, macromolecules offer structural support, a way to store energy, and the capacity to store and access genetic data.
What do food macromolecules do?Large molecules known as macromolecules are produced when monomers, or tiny units, are polymerized. The majority of macromolecules are found in commonplace items like food. Biological macromolecules come in a variety of forms, including carbohydrates, proteins, lipids, and nucleic acids.

what is the total amount of carbon added to the atmosphere from soil and the burning of fossil fuel
Answer:
When people use fossil fuels to power industries, power plants, automobiles, and trucks, the majority of the carbon is released into the atmosphere as CO2. The combustion of fossil fuels releases 5.5 billion tons of carbon per year. 3.3 billion tons of this huge quantity remains in the atmosphere.

Two plants are crossed, and the traits of height and color are assessed in the offspring. The following cross was conducted: TTPP x ttpp. Which of the

T = dominant allele for height, tall plant
t = recessive allele for height, short plant
P = dominant allele for color, purple
p = recessive allele for color, white

O All are tall and purple
O Three-quarters of the plants are short and white
All are short and white
Three-quarters of the plants are tall and purple
Answer:
A. All are tall and purple
Explanation:
When you set up a punnet square, all of the results would be TtPp.
When a dominant trait is present, it preceeds over the recessive trait. (Also it depends on what genotypes are given. Ex: In flowers if they gave RR shows red, Rw shows pink, and ww shows white, but that's not the case here given that there are only 2 genotypes).
So to break it down:
Tt -> tall plant
Pp -> purple plant
so they are all tall and purple.

true or false: cardiac contractile cells have thick and thin filaments arrangement in sarcomeres.
Answer:
True
Explanation:
This is because sacromere is the basic unit of cardiac muscles which is made up of thin and thick filaments. Cardiac muscle is consist of the contractile cells of the heart which it's appearance is striated as a result of alternating thick and thin filaments which is composed of myosin and actin. Actin and myosin are both firm contractile protein filaments, the actin form the thin filaments, and myosin form thick filaments.

what makes lipids/fats hydrophobic?
Answer:
Lipids are hydrophobic because they do not mix with water. Lipids are made of long chains of carbon and hydrogen. ... The partial charges on the water molecule cannot interact with the neutral lipid molecule and thus water and lipids do not mix.
Answer:
"this hydrophobic ("water fearing") nature of lipids is driven by the bonds between these many carbons and hydrogens. ... Thus, long chains of carbon-hydrogens bonds form a nonpolar molecule."
A scientist exploring in the rainforest found an unclassified organism. It is multicellular and made of multiple thread-like structures. The organism has cells with a nucleus and a cell wall made of chitin. The scientist should classify this organism as belonging to the kingdom—
Answer:
Kingdom Fungi
Explanation:
Based on certain characteristics possessed by living organisms, they have been classified into five different kingdoms namely; plantae, animalia, monera, protista and fungi. Organisms with similar characteristics have been placed under the same kingdom.
Kingdom Fungi is a kingdom that contains organisms that possess characteristics different from plants and animals. Some of these features are those possessed by the unclassified organism found in the rainforest and they are as follows:
- They are eukaryotic (possess a true nucleus) and multicellular (have more than one cell).
- Their cell wall is made of chitin (a carbohydrate)
- They are made of multiple thread-like structures called HYPHAE.
Based on these mentioned characteristics above, the scientist should classify this organism as belonging to the kingdom FUNGI.

When both lactose and glucose are available to E. coli, which part of the lac operon regulation assures that glucose will be metabolized first? When both lactose and glucose are available to E. coli, which part of the lac operon regulation assures that glucose will be metabolized first? Permease allows lactose to enter the cell when lactose enters the cell. The repressor binds to the operator in the absence of lactose. The repressor cannot bind to the operator in the presence of lactose. RNA polymerase transcribes the lac operon to make a single RNA molecule. CAP binds to cAMP and then to the promoter only in the presence of low glucose.
Answer:
CAP binds to cAMP and then to the promoter only in the absence of low glucose
Explanation:
When both lactose and glucose are available to E. coli, the part of the lac operon regulation that assures that glucose will be metabolized first is

Which type of macromolecules helps a cell brake down food? Lipids proteins carbonhydrates or nucliec acids
Answer:
Proteins
Explanation:
There are four major biomolecules found in living system namely; proteins, carbohydrates, lipids and nucleic acids. These biomolecules serve different and unique functions in the body. PROTEIN is a biomolecule that helps in the break down of food substances in the body as stated in this question.
Specifically, these function of breaking down food substances is carried out by ENZYMES, which are biological catalysts that are proteinous in nature i.e. structurally made of proteins. For example, amylase enzyme breaks down starch, lipases break down lipids. Hence, since enzymes that perform this disintegration function are PROTEINOUS, then PROTEINS are the biomolecules that perform the role.

d. the orbiting of an object around another object
5.
gravity
e. the spinning of a celestial body, such as a planet, around
an axis
Answer:
Axis - B
Rotation - E
Revolution - D
Latitude - A
Gravity - C
Explanation:
The axis is the line that a body spins on. The axis will line up with the north and south poles. For Earth, the axis is tilted, which is why seasons exist.
The definition of rotation is "the action of rotating around an axis or center." So, rotation is the spinning of a body on its axis. On Earth, one rotation is equal to one day.
Revolutions are when a body spins around another. For Earth, one revolution around the sun is one year
Latitudes are invisible lines that separate the world into degrees from North to South. They are also called parallels.
Gravity is the force that keeps things together. Large masses have gravity that attract other masses.
