<h2>
Vascular and Nonvascular Plants </h2>
Explanation:
Kingdom Plantae on the basis of vasculature is divided into two groups-vascular and non-vascular plants
.
- <u>Vascular plants </u>or tracheophytes have a proper tissue-level organization and true shoot and root structures like leaves, stem, flowers, root etc
- The tissue system or vasculature of vascular plants compromises of vascular tissues like tubular vessels – xylem and phloem
- The xylem transports nutrients to various parts of the body from the leaves.
- Phloem conducts water and other nutrients from the roots to various parts of the plant
.
- These are flowering plants that include the phanerogams – angiosperms and gymnosperms and bears flowers and fruits like the cedars, pine, clubmosses, lilies, sunflower etc.
- Dicots are with tubular vasculature.
- Non-vascular plants or bryophytes with an absence of proper tissue-level organization and true shoot or root systems
- <u>Nonvascular plants</u> are small. Their transport mechanism is poor due to lack of vascular tissues
- These plants are lack proper shoot or root system.
- It includes mosses, hornworts etc.
- Monocots are plants with scattered tube-like vessels

4) d. four
Explanation:
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).
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.
Histones are a group of highly basic proteins that are mainly associated with deoxyribonucleic acid (DNA) in the nucleus of a living organism and then condense it to chromatin.
Histones include five main classes of relatively small basic proteins containing relatively large amounts of lysine and arginine. Nucleosomes are made of two each of four types of histones.
Answer:
initially, collects in the structure indicated by the letter B
Explanation:
Filtrate is formed as fluid is forced through the walls of the glomerulus and, initially, collects in the structure indicated by the letter B.
Urine formed by a kidney collects in the renal pelvis before being drained from the kidney by the urethra and transported to the urinary bladder.
The process by which glomerulus filtration occurs is called renal ultrafiltration. The force of hydrostatic pressure in the glomerulus (the force of pressure exerted from the pressure of the blood vessel itself) is the driving force that pushes filtrate out of the capillaries and into the slits in the nephron.
Answer: its A boiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii
Explanation:
Well, using Math to see how far the Moon is from the Earth could be hard. Also, he saw that the Moon is moving in a "circle" instead of flying off, so the Earth did have a pull on the Moon so that it didn't fly away. Newton had to use Math in order to be able to identify what it's now called gravity. There's a lot that the Moon has to offer, there were no computers back then, so there's was no calculator and everything had to be done by hand.
