Answer:
importancia de la luz y la cloro fila
Answer:
Light and chlorophyll are necessary for plants to photosynthesise. Photosynthesis is when plants use sunlight and carbon dioxide to make glucose. But chlorophyll is required to make this happen. It's important that plants make their own food so they don't die, since plants are the number one source of oxygen.

Explanation:
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. 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.

Define or give an example of an ecosystem
Answer:
The simplest definition of an ecosystem is that it is a community or group of living organisms that live in and interact with each other in a specific environment.
Seas, rivers
Explanation:
this is the correct answer you want
Answer:
An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system. These biotic and abiotic components are linked together through nutrient cycles and energy flows.

What is the name of a group of connected and related organisms? A. Flow B. Matter C. System D. Energy
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.

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.
Segments of DNA, or genes, contain specific sequences that are transcribed as mRNA and translated to produce specific _____________.
Answer: i think the answer would be proteins, but please dont kill me if it isnt :( im in midle school so we recently covered this.
Explanation
heres the deal
dna- transcribed to rna example: AGT- UCA, then you trabslate it, which then turns into specific proteins after being coded by codons (3 nucleotides put together.) hope this helps!
think nucleotide= A or G or C or T
CODES: A codes for T
C 4 G
in RNA, Thymine (T) codes for Uracil (U)
