Answer:
first it start from small atoms and change slow
Endocytosis enables extensive particles to enter the cell, and exocytosis ousts vast atoms from the cell. Along these lines, the cell can acquire things it needs and disposes of things it doesn't. Exocytosis is the turn around process, where a cell ousts substantial particles, generally squander from cell forms.
Answer:
Option 4
Explanation:
Folate is vitamin B and occurs naturally in various food items such as green leafy vegetable, lentils, peas, beans, in fruits such as banana, melon, and enriched products such as bread, juices etc. Folate is essential for making up genetic material or DNA. Out of all given options, option 4 has both lentil and spinach (green leaves) which are rich source of folate. Option 1 has bread as a source of folate. Hence, the correct answer is option 4.
B. a specific place on a chromosome where a particular gene resides.
A locus (plural loci) in genetics is the position of a gene on a chromosome. Each chromosome carries many genes; humans' estimated 'haploid' protein coding genes are 19,000-20,000, on the 23 different chromosomes. A variant of the similar DNA sequence located at a given locus is called an allele.
Here, we are required to list six of the properties of water and how they are essential for the existence of life.
These properties include:
- Water is a universal solvent
- Water is highly cohesive
- Water is a Substrate for microbial proliferation.
- Water supports cellular structure.
- Water has considerable buffering capability.
- Water is involved in Catabolic and Anabolic reactions.
- Water as a universal solvent is evident in its extensive capability to dissolve a variety of molecules and consequently transport them has earned it the designation of “universal solvent,” and it is this ability that makes water such an invaluable life-sustaining force. Biologically, water’s role as a solvent helps cells transport and use substances like oxygen or nutrients such as water-soluble vitamins.
- The cohesive property of water molecules helps plants take up water at their roots. Cohesion also contributes to water’s high boiling point, which is vital in animals body temperature regulation.
- Water serves as a substrate for Microbial proliferation because microorganisms grow best in high moisture environment.
- Water supports cellular structure: Water is quite important in biological structures. Water fills cells to help maintain shape and structure. The water inside many cells (including those that make up the human body) creates pressure that opposes external forces, similar to putting air in a balloon thereby creating a cushion.
- Water has considerable buffering capability: water buffers cells thereby protecting them from the dangerous effects of acids and bases. Highly acidic or basic substances, like bleach or hydrochloric acid, are corrosive to even the most durable biological materials.
- Water is involved in Catabolic and Anabolic reactions: Water is directly involved in biochemical reactions to build and break down important components of the cell. Photosynthesis, the process in plants that creates sugars for all life forms, requires water. Water also participates in building larger molecules in cells.
