Answer: Angiosperms represent approximately 80 percent of all known living green plants. Examples range from the common dandelion to ancient flowers such as magnolias. Angiosperms also make up the vast majority of all plant foods we eat. (Ex. grains, vegetables, and fruits.) The angiosperms are vascular seed plants in which the ovule (egg) is fertilized and develops into a seed in an enclosed hollow ovary The ovary itself is usually enclosed in a flower, that part of the angiospermous plant that contains the male or female reproductive organs or both. fruits are derived from the maturing floral organs of the angiospermous plant and are therefore characteristic of angiosperms.

Wether the apple has a taproot or a fibrous root
Answer:
taproot
Explanation:
Apple trees roots consist of a deep taproot and lateral fibrous roots. The taproot is analogous to the carrot, which is a taproot. Lateral fibrous roots can extent to more than twice the spread of the canopy of the apple tree and are influenced by soil, water availability and competition from the roots of other plants.
Answer:Tap roots.
Explanation:Because the roots are long.

What is the building unit that enters the plant cell organelle membranes?
A -fatty acids
b -ribose sugar
c -simple lipids
d -nucleic acids
Answer:
It's b ribosome sugar
Mark as brainliest
The building unit that enters the plant cell organelle membranes is ribose sugar. When the ribose sugar enters it has to break down into various substituents.
What is the number of carbons in ribose sugar ?The number of carbons in ribose sugar is 5. It is a pentose sugar.
Fatty acids can not pass through the cell membrane as it is very big in size and because of its very larger size it is nearly not possible to enter through the cell membrane.
Simple lipid are present in the cell membrane that is it is following the fluid mossaic model that is the two layers of lipids are present om the cell membrane where the proteins are present on the outer layer. Various types of proteins are present on the membrane.

B. RADIATION FROM X-RAYS CAUSES A MUTATION IN BRAIN CELL.
C. A CHEMICAL AND CIGARETTE SMOKE CAUSES A MUTATION IN A LUNG CELL.
D. A SUBSTITUTION IN DNA CODING CAUSES A MUTATION IN A SPERM CELL.
I THINK ITS D. BUT CAN SOMEONE HELP ME !!!!!
Answer:
yeah
Explanation:
it's obviously D . it's a heritable change because the mutation in the sperm cell is gonna cause a mutation in the zygote
A mutation in the sperm cell will most likely result in heritable change ton the attributes of organisms.
Mutations that happen in vegetative cells such as skin, lung, and brain cells cannot be passed on to future generations.
Heritable mutations are those changes to the DNA sequence of sex cells. Changes elicited by such mutations are passed to future generations because they are germline based.
Sperm cells are sex cells. Thus, changes that occur as a result of mutation to sperm cells are most likely heritable.

what solution, (hypertonic, hypotonic, isotonic) would make osmosis go faster?
Answer:
Explanation:
Osmosis is the movement of WATER molecules across a semipermeable membrane (such as the cell membrane) from where there is a high concentration of water to where there is a low concentration of water. The interior of a living cell consists of cytoplasm, which is a solution of mostly water with dissolved substances such as salt.
Now for the fun stuff! An Isotonic solution is a solution that has the same concentration of dissolved substances as is found inside the cell. If a cell is surrounded by isotonic solution, then there is no net movement of water across the membrane by osmosis, because the concentration of water is the same on both sides of the membrane.
A hypertonic solution is a solution with a higher concentration of dissolved substances than is found inside the cell. If a cell is surrounded by hypertonic solution, then water will move OUT of the cell by osmosis because there is a higher concentration of water inside the cell compared to outside (where there is lots of dissolved salt, etc.) A cell in hypertonic solution will shrink.
A hypotonic solution is a solution with a lower concentration of dissolved substances than is found inside the cell. If a cell is surrounded by hypotonic solution, then water will move INTO the cell by osmosis because there is a higher concentration of water outside the cell compared to inside. A cell in hypotonic solution will swell up and, if there is no cell wall, may burst. A silly but simple way to remember that water moves into a cell in hypotonic solution is that "hypo causes the cell to swell up like a hippo"

Here is an image of the mitochondria. Mitochondria numbers can differ between cell types based on the function of the cell. Which of these cells would contain the highest number of mitochondria? A) skin cell B) lung cell C) muscle cell D) red blood cell.
The cell organelle that produces most of the energy for cell functioning and growth is mitochondria. Mitochondria is a double membrane organelle that varies in number in cells.
The highest number of mitochondria is found in:
Option C) Muscle cells
The function of mitochondria can be explained as:
Muscle cells and tissues are bodily organizations that constantly and frequently move so to provide energy for the actions the muscle cells have the highest number of mitochondria.The skin and lungs cells vary in mitochondrial quantity and may contain hundreds or thousands. Some amount of cell requires more amount of energy as compared to others so the number of mitochondria in those cells will be more.The blood cell of mammals lack mitochondria in their structure.Therefore, muscle cells have the highest number of mitochondria.
