Answer:
B. nucleotides
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
A nucleotide can be defined as an organic molecule which forms the building block of nucleic acid such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Deoxyribonucleic acid (DNA) is an organic complex-molecular structure found in all living organisms. It comprises of genes and is essentially the foundation block of all living organisms such as humans, animals and plants.
Basically, nucleotide comprises of the following parts;
1. Nitrogenous base: this includes adenine (A), thymine (T), guanine (G), and cytosine (C) which are mainly found in the DNA while adenine (A), guanine (G), uracil (U) and cytosine (C) are found in the RNA.
2. A phosphate group.
3. A penrose sugar: it is either deoxyribose in DNA or ribose in RNA.
The two parts or chemical components of a nucleotide which do not change throughout the structure of DNA are;
I. Five-Carbon Sugar also known as deoxyribose and it has hydrogen on its second carbon.
II. Phosphate: this is the structural backbone that provides support to DNA.
In conclusion, the proteins which are mainly synthesized based on the genetic instruction codes in deoxyribonucleic acid (DNA) determines the trait of living organisms. A sequence of biomolecules which are responsible for this coded genetic instructions in all living organisms is known as nucleotides.

Answer:
Describe the two eukaryotic animal organelles that have roles similar to the organs of the human digestive system
→Two eukaryotic animal cell organelles that have roles similar to the organs of the human digestive system are lysosome and mitochondria.Describe how proteins are made packaged and transported within the cell
→Vesicles transport the proteins from the ribosomes to the Golgi apparatus, a.k.a Golgi complex, where they are packaged into new vesicles. The vesicles migrate to the membrane and release their protein to the outside of the cell. Lysosomes digest and recycle the waste materials for reuse by the cell.Answer:

Which of the following is composed of monosaccharide monomer units? A.nucleic acids B. proteins C.carbohydrates D. lipids
No LINKS PlEASE
Answer:
c
Explanation:
Monosaccharides are the building blocks of disaccharides (such as sucrose and lactose) and polysaccharides (such as cellulose and starch).
Higher Classifications: Carbohydrate; Sugar
The correct option is (c) carbohydrates .
The monomer units for constructing DNA and RNA are nucleotide bases, whereas amino acids, sugar residues, fatty acids, and acetyl groups are the monomers for proteins, carbohydrates, and lipids, respectively.Large polymers made of hundreds of monosaccharide monomers are known as polysaccharides, sometimes known as glycans. Polysaccharides, in contrast to mono- and disaccharides, are not sweet, and they typically are not soluble in water. The monomeric units of polysaccharides are joined by glycoside, linkages, just like disaccharides.What units are carbohydrates made up of?In the case of carbohydrates, the small repeating units are called monosaccharides. Carbohydrates contain only carbon, hydrogen, and oxygen.Learn more about monosaccharide monomer units brainly.com/question/4939229

one.
A. Choose one way a predator captures prey and describe it.
B. Choose one way prey avoid predators and describe it.
Answer:
Remaining silent.
Explanation:
Remaining silent, seeking refuge, and reducing overall activity levels are the ways that is used by the prey to avoid or to save itself from the predators. The prey remain silent when its senses the presence of predators because to stop giving cues to the predators to its presence. Some prey hide itself in the place for sometime in order to save itself from the attack of the predator while some preys decreases daily activities in order to decrease the cues given to the predator for its presence.

4. A woman with defective tooth enamel (autosomal recessive) and normal color vision, (X-linked) who had a color blind father with normal tooth enamel and a mother with normal vision and defective tooth enamel, marries a color blind first cousin with normal tooth enamel who had a father with defective tooth enamel. What is the probability of their having a child with normal tooth enamel and color blindness
Answer:
The probability of their having a child with normal tooth enamel and color blindness is 3/8 or 0.375
Explanation:
Let the alleles for normal and defective tooth enamel be T and t respectively.
Color blindness is on the X-Chromosome. Let the allele normal vision and colour blindness be Xn and Xc respectively.
The woman had a colour blind father (XcY) and a normal vision mother, so her allelic pair for vision will be XnXc.
Her father had normal tooth enamel while her mother had a defective tooth enamel, therefore, she will have the allelic pair, Tt.
Her genotype for vision and tooth enamel will be XnXcTt.
Her husband who is color blind with normal tooth enamel had a father with defective tooth enamel, tt. Therefore, her husband's genotype for vision and tooth enamel will be XcYTt.
From the dihybrid cross of XnXcTt and XcYTt, the following offspring are obtained:
XnXcTT, XnXcTt, XnYTT, XnYTt
XnXcTt, XnXctt, XnYTt, XnYtt
XcXcTT, XcXcTt, XcYTT, XcYTt
XcXcTt, XcXctt, XcYTt, XcYtt
From the results of the cross, a child with normal tooth enamel and color blindness will have the following genotypes: XcXcTT, XcXcTt, XcYTT, XcYTt, XcXcTt, XcYTt.
Probability of their having a child with normal tooth enamel and color blindness = 6/16 = 3/8 or 0.375

1. 64% water, 14% protein, 16% fat, 4% minerals and 1% carbohydrates
2. Macromolecules come from Food
3. Catabolic, Anabolic, and Metabolism
What do you mean by metabolism?Metabolism is the set of life-sustaining chemical reactions in organisms. The three main purposes of metabolism are: the conversion of the energy in food to energy available to run cellular processes.
Moreover, it is the process by which the body changes food and drink into energy. During this process, calories in food and drinks mix with oxygen to make the energy the body needs. Even at rest, a body needs energy for all it does.
Hence, if your metabolism is "high" (or fast), you will burn more calories at rest and during activity. A high metabolism means you'll need to take in more calories to maintain your weight. That's one reason why some people can eat more than others without gaining weight.

Coniferous trees flourish because they take the opposite approach of deciduous trees: they grow (slow/fast) and die (young/old). Question 4 options: fast, young slow, young slow, old fast, old
Answer:
D. Coniferous and Deciduous trees
Explanation:
These trees are found in the humid subtropical climate areas.
Correct on edg. 2020
Coniferous trees grow slow and die old as compared to Deciduous trees.
What do you mean by Coniferous trees?Coniferous trees may be defined as mostly evergreen trees and shrubs having usually needle-shaped or scalelike leaves and including forms with true cones and others with an arillate fruit.
Deciduous trees tend to grow faster than evergreen trees. They have broader leaves as compared to evergreen trees. Coniferous trees have needles instead of leaves. They don't change color in the fall.
Therefore, Coniferous trees grow slow and die old as compared to Deciduous trees.
