Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption. They also contain lots of mitochondria , which release energy from glucose during respiration in order to provide the energy needed for active transport.

Compare and contrast meiosis and mitosis. How many daughter cells are produced by each, and how many chromosomes do they have? In what contexts do meiosis and mitosis occur?
Answer:
In mitosis, the daughter cells have the same number of chromosomes as the parent cell, while in meiosis, the daughter cells have half the number of chromosomes as the parent.Mitosis and meiosis are two different kinds of cell cycle reproduction. They have many things in common together, such as being an asexual form of reproduction. Mitosis produces body cells, identical daughter cells that can grow an organism and replace old/dead cells. Meiosis on the other hand makes gametes; or reproductive cells. When mitosis happens, it goes through stage of the mitotic phase known as PMAT. PMAT stands for: prophase, metaphase, anaphase, and telophase; followed by cytokinesis. Meiosis on the other hand, goes through PMAT twice. After mitosis, the product is 2 identical cells, which are used to replace cells or to grow. After meiosis, 4 NON-identical cells are made, which contain HALF the set of chromosomes; hence being called a haploid cell.
Explanation:
Answer:
see explanation
Explanation:
Meiosis is involved in gamete reproduction and results in four genetically distinct daughter cells. In contrast, mitosis involves the somatic cell and results in two genetically identical daughter cells. In mitosis when the division is complete you have two diploid cells. A diploid cell has two sets of chromosomes. Whereas with meiosis whose goal is to produce gametes you end up with 4 haploid cells. A haploid cell has just a single set of chromosomes. Meiosis and mitosis go through very similar phases however meiosis crossing over takes place and variation occur. Mitosis the division takes place in four stages and in Meiosis there is a two-division process of four stages each.

a)State the role of saliva in human beings b) State 2 hormones involved in digestion
Answer:
A) The digestive functions of saliva include moistening food, and helping to create a food bolus, so it can be swallowed easily.
B) The five major hormones are: gastrin ( stomach ), secretin ( small intestine ), cholecytokinin (small intestine), gastric inhibitory peptide (small intestine), and motilin (small intestine).
Explanation:
Explanation of answer A):
Saliva contains the enzyme amylase that breaks some starches down into maltose and dextrin. Thus, digestion of food occurs within the mouth, even before food reaches the stomach.

PLease give a very good summary on the Cilia And Flagella.
Must be 1 paragraph atleast
(Please everything about must as much as you know please)
Answer:
Cilia and flagella are slender, hair-like structures that protrude from many types of cells. In many cells, cilia act as a fundamental unit of motion, serving as key organelles that convert chemical energy into mechanical work in the form of an oscillatory beating motion.Flagella acts primarily as an organelle of locomotion in the cells of many living organisms.In multicellular organisms, cilia function to move a cell or group of cells or to help transport fluid or materials past them.Cilia are present on the surface of the cell in much greater numbers. Ciliated cells often have hundreds of cilia but flagellated cells usually have a single flagellum. The function of cilia is to move water relative to the cell in a regular movement of the cilia.

2.The equator is closer to the Sun than the North Pole
3.The equator receives more direct sunlight than the North Pole.
4.The equator has more hours of daylight per year than the North Pole.
Answer:
3. The equator receives more direct sunlight than the North Pole.
Explanation:
The equator is the longest latitude at 0°.The equator isn't influenced any change when the earth revolves around the sun cause winter and summer. That's why equator is warmer than north and south pole.I hope you understoodHELP ME ASAP PLEASE.
How does water move from leaves to root? explain
Answer:
During transpiration, water will evaporate from tiny holes in the surfaces of leaves into the air (the tiny holes are called stomata). As the water molecules evaporate from plant leaves, they attract the water molecules still in the plant, helping to pull water up through the stems from the roots.

True or False: Biodiversity makes living things resilient.
The statement "Biodiversity makes living things resilient" is absolutely false.
What is Biodiversity?Biodiversity may be defined as the sum total of all the varieties of living organisms present on the surface of the earth. This huge biodiversity makes the environment which is good and healthy for the life of each organism.
Biodiversity never plays a role in the resilience of living things. As it only deals with the presence or existence of the number of living forms on the surface of the earth. But yes, it is true that each organism delivers some flexibility to the ecosystem. For example, the presence of bacteria and some other microorganisms act as decomposers which decompose dead and organic remains.
Therefore, the statement "Biodiversity makes living things resilient" is absolutely false.

Compare and contrast a frameshift mutation and a single nucleotide substitution mutation in a DNA sequence encoding a protein. How many nucleotides would be inserted or deleted in each? How many amino acids in the protein sequence would be altered in each?
Answer:
look at the explanation
Explanation:
In frameshift mutations, the addition or deletion of 1,2 or 4 nucleotides occurs, which changes the ribosome reading frame. In single-nucleotide substitution, only one is substituted, as the name implies. A single substation is when one of our DNA bases is replaced with another and changes one amino acid. In Frame-shift, mutations usually have more significant effects on the final proteins. Frame shifts can affect the entire chain of proteins.
