What is a nucleic acid? Explain your answer.

Answers

Answer 1

Answer: Nucleic acids are the main information-carrying molecules of the cell

Answer 2

Answer: Nucleic acids are the main information-carrying molecules of the cell, and, by directing the process of protein synthesis, they determine the inherited characteristics of every living thing.

Explanation:

What would most likely happen to plants if they did not have a waxy outer coating?

Answers

They would dehydrate too rapidly and die. Plants (well, plants with true vascular systems) need to have water to dehydrate from the leaves to help draw the water up from the soil. This is transpiration, but without the waxy cuticle this would occur at an excessive rate, killing the plant.

Answer:

Water is drawn upward from the roots through plant tissue to the leaves by

Answers

water exaporates frm the leaves and other parts of the plant above the ground. The evaporation of water from the plant is called ''transpiration''. It occurs mainl through the stomata. However, as quickly as water is lost from the leaves, more water enters the roots and flows up the stem. The water flows up the plant in narrow pipes, rather like capillary tubes. These tubes make up the xylem. The walls of the tubes are made of lignin, which is hard and waterproof. In trees and shurbs the xylem tubes are one of the main components of wood. They do not contain living material and are therefore dead.` Water rises up the stem mainly by being ''pulled'' from above. The ''pull'' is created by the evaporation if water from the leaves. If you stop this by, for example, cutting iff the leaves or blocking the stomata, the flow of water up the stem slows down or stops. The drier the atmosphere, the greater is the rate of transpiration. In very dry wather, water may evaporate from the leaves faster than it is replaced from the soil. The plant then suffers from water shortage. Normally a plant's cells are full of water, and all the cells are pressing against each other within the epidermial covering. This helps to support the plant amd holds the leaves out flat. If a plant runs short of water, the cells lose water and go flabby. The plant then droops. This is called wilting. Plants living in dry places have all sorts of adaptations for not

The organic chemicals that help cell membranes to conserve internal fluids are _____. a. hormones
b. phospholipids
c. amino acids
d. proteins

Answers

the most appropriate answer is B ! as it helps in maintaining isolated internal environment !!

The organic chemicals that help cell membranes to conserve internal fluids are the phospholipids. They are composed of fatty acid, glycerol, phosphate group and a polar molecule. The phosphate group and polar head region of the phospholipids is attracted to water while the fatty acid is repelled by water. They are a major component of the cell membrane in which it encloses the organelles of the cell. It also limits what enters and exits the cell because of its two heads.

Explanation:

Which term describes body structures in different organisms that have different outward appearances but develop from the same embryonic tissues?A) analogous
B) homologous
C) remedial
D) vestigial

Answers

Answer:

The correct answer would be B) homologous.

Homologous organs refer to the set of organs which have different appearance and function but share common anatomy due to common ancestry.

For example, the forearm of human, forelimb of the horse, wing of a bat, wings of birds, and seal's flipper share common underlying anatomy. They are made up of same sets of bones (humerus, radius, ulna, carpels, metacarpals, and phalanges).

These organs are adapted to perform different functions in an environment.

It is also observed that these organs developed in the same manner in the embryo and from similar origins.

The answer is B) Homologous
