Transpiration is the evaporation of water from the surface of a plant. Explain.
Answer:
Transpiration is the loss of water from a plant in the form of water vapor. Water is absorbed by roots from the soil and transported as a liquid to the leaves via xylem. In the leaves, small pores allow water to escape as a vapor. Of all the water absorbed by plants, less than 5% remains in the plant for growth.
1. An anatomy student was arguing with his grandfather. Granddad, who believed in folk wisdom, insisted that there are only five senses. The student, however, said that there are at least ten senses. Decide who is right, and then list all the senses.
Answer:
Granddad is right.
Explanation:
Granddad is right that there are five senses such as eyes, ears, skin, nose, and mouth. There are five sense organs that helps in sensing external environment present around the individual. Through eyes we can see our surrounding, ears can help us to hear different sounds, through skins we can sense the temperature of the surrounding, nose help us to smell different odors and mouth help us to taste different types of food. These five senses are very important for the survival of people.

Achromoplast stores while a leucoplast stores A. starch; pigments B. chlorophyll; starch C. pigments; chlorophyll D. pigments; starch
Answer:
D. pigments; starch.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles.
A chromoplast can be defined as a heterogeneous organelle or plastids that is typically responsible for pigment synthesis and their storage in a plant. The pigments include red, orange, yellow or chlorophyll.
On the other hand, leucoplast is a colorless plastid i.e plastic lacking photosynthetic pigments that are typically found in storage organs, underground stems, cotelydons, roots, tubers, seeds, or endosperm etc., used for the storage of starch in the absence of sunlight.
Hence, a chromoplast stores pigments while a leucoplast stores starch.
what caused a decrease of carbon dioxide in the biodomes air
Answer:
As organisms release energy during cellular respiration, carbon dioxide is produced from the carbon in energy storage molecules. ... Carbon dioxide in the biodome decreased because decomposers decreased which means there was a decrease in cellular respiration overall.
There are several possible reasons why the carbon dioxide levels in the air of a biodome might decrease like photosynthesis, respiration, ventilation and carbon sequestration.
What are the factors responsible for decrease of carbon dioxide in the biodomes air?There are several possible reasons why the carbon dioxide levels in the air of a biodome might decrease. Some possible causes include:
Photosynthesis: If the biodome contains plants, they may be using carbon dioxide during photosynthesis to produce oxygen and glucose. This process would remove carbon dioxide from the air.
Respiration: If the biodome contains animals or microorganisms that respire, they may be consuming oxygen and producing carbon dioxide. This would result in a decrease in carbon dioxide levels in the air.
Ventilation: If the biodome has a ventilation system, it may be designed to remove excess carbon dioxide from the air. This could result in a decrease in carbon dioxide levels.
Carbon sequestration: If the biodome has systems in place to capture and store carbon dioxide, such as through the use of plants or other methods, this could result in a decrease in carbon dioxide levels in the air.
It's important to note that the specific cause of a decrease in carbon dioxide levels in the biodome's air will depend on the specific conditions and systems in place within the biodome.

describe the structure and functions of various organelles in a mature animal cell
Answer:
Explanation:
Cell Membrane
A thin semipermeable membrane layer of protein and fats surrounding the cell. Its primary role is to protect the cell from its surrounding. Also, it controls the entry and exit of nutrients and other microscopic entities into the cell.
Nuclear Membrane
It is a double-membrane structure that surrounds the nucleus. It is also referred to as the nuclear envelope.
Nucleus
It is an organelle that contains several other sub-organelles such as nucleolus, nucleosomes and chromatins. It also contains DNA and other genetic materials.
Centrosome
It is a small organelle found near to the nucleus which has a thick centre with radiating tubules. The centrosomes are where microtubules are produced.
Lysosome (Cell Vesicles)
They are round organelles surrounded by a membrane and comprising digestive enzymes which help in digestion, excretion and in the cell renewal process.
Cytoplasm
A jelly-like material which contains all the cell organelles, enclosed within the cell membrane. The substance found within the cell nucleus, contained by the nuclear membrane is called the nucleoplasm.
Golgi Apparatus
A flat, smooth layered, sac-like organelle which is located near the nucleus and involved in manufacturing, storing, packing and transporting the particles throughout the cell.

1. Which statement is true about DNA?
a. DNA is an exact copy from parent to offspring.
b. DNA is not necessary for an organism to reproduce.
c. DNA contains genes that hold specific traits for an organism.
d. Organisms create their own DNA sequence that is not like their parents.
Answer: C
Explanation:
Name some organisms that reproduce through binary fission.
- Amoeba
- Pumilus
- Cereus
- Euglena
-----------------------------------------------------------------------------------------------------------------
If a organism reproduce through binary fission, they're dividing into two parts and the regeneration of those 2 parts. Mostly bacteria reproduce using binary fission and most cells do the same thing. It's a type a asexual reproduction. Like I said before, they divide instead of being one. The parent cell divides into 2 identical cells, growing into size.
