plzzzz help me!!!!!! A euglena is a unicellular organism. Explain how the euglena's cell parts help it stay alive. Please don't make it SUPER long like the others I just want around 3-5 sentences :)
Answer:
Chloroplasts within the euglena trap sunlight that is used for photosynthesis, and can be seen as several rod like structures throughout the cell. Color the chloroplasts green. This helps the euglena find bright areas to gather sunlight to make their food.
Explanation:
the Phylum Euglenophyta. All euglena have chloroplasts and can make their own food by photosynthesis. They are not completely autotrophic though, euglena can also absorb food from their environment; euglena usually live in quiet ponds or puddles.
Euglena move by a flagellum (plural ‚ flagella), which is a long whip-like structure that acts like a little motor. The flagellum is located on the anterior (front) end, and twirls in such a way as to pull the cell through the water. It is attached at an inward pocket called the reservoir. Color the reservoir grey and the flagellum black.
The Euglena is unique in that it is both heterotrophic (must consume food) and autotrophic (can make its own food). Chloroplasts within the euglena trap sunlight that is used for photosynthesis, and can be seen as several rod like structures throughout the cell. Color the chloroplasts green. Euglena also have an eyespot at the anterior end that detects light, it can be seen near the reservoir. This helps the euglena find bright areas to gather sunlight to make their food. Color the eyespot red.Euglena can also gain nutrients by absorbing them across their cell membrane, hence they become heterotrophic when light is not available, and they cannot photosynthesize.
The euglena has a stiff pellicle outside the cell membrane that helps it keep its shape, though the pellicle is somewhat flexible and some euglena can be observed scrunching up and moving in an inchworm type fashion. Color the pellicle blue.
In the center of the cell is the nucleus, which contains the cell's DNA and controls the cell's activities. The nucleolus can be seen within the nucleus. Color the nucleus purple, and the nucleolus pink.
The interior of the cell contains a jelly-like fluid substance called cytoplasm. Color the cytoplasm light yellow. Toward the posterior of the cell is a star-like structure: the contractile vacuole. This organelle helps the cell remove excess water, and without it the euglena could take in some much water due to osmosis that the cell would explode. Color the contractile vacuole orange.
Answer:
The contractile vacuole controls the intracellular water balance by collecting and
removing excess water out of the cell, allowing cells to survive under hypotonic
stress as in pond water. The cell membrane protects the inner part of the cell
from the outside environment. The flagellum enables movement and chemotaxis.
Chloroplasts harvests light energy. The nucleus controls and regulates the
activities of the cell. A Mitochondrion generates most of the chemical energy
needed to power the cell's biochemical reactions. All of these things make up the
euglena.

A ______occurs when the Earth casts a shadow that partially or fully covers the Moon
O lunar eclipse
O summer solstice
O solar eclipse
Answer:
Lunar eclipse
Explanation:
During a lunar eclipse, the earth enters between the sun and the moon, thus preventing sunlight from reaching the moon. There are two types of lunar eclipses: A total lunar eclipse occurs when the moon and the sun are on opposite sides of the earth. When only part of the earth's shadow covers the moon, a partial lunar eclipse will occur. In some cases, it is called a blood moon, similar to the blood moon that occurs this month.

The cell cycle is the life of the cell from the time it is first formed from a dividing parent cell until its own division into two cells
Explanation:
cell cycle is made up of three main parts: interphase, mitosis, and cytokinesis. Most biologists agree that interphase makes up the period of time that a cell would be preparing for cell division. Cells spend the majority of their lives in this stage. During interphase a cell is going to be growing, replicating its genetic material and essentials to carry out cell division, and proofreading the genetic material to ensure replication has occurred correctly. This doesn’t sound like much, but it’s actually the longest part of the cell cycle. Once this is complete, the cell will then go through cell division and, theoretically, split into two new cells (cytokinesis).
How cytokinesis works will depend upon the type of cell that is dividing. Here is an image that summarizes the differences in cytokinesis in plant cells and animal cells, which is the classic example used in many introductory biology courses:
What is a community? (Please don’t put links!!)
A)a population that lives in a single habitat

D)all the animals that live in a habitat

option C is the correct one .
A Cotton shirt takes more time to dry as compared to a synthetic shirt. Why?
Answer:
Due to absorption of more water.
Explanation:
A Cotton shirt takes more time to dry as compared to a synthetic shirt due to absorption of more water by the cotton fiber as compare to other fiber. Cotton absorbs much more water than other synthetic fibers, and attached to the molecules of cotton for longer period of time which means cotton fibers take more time to dry as compared to synthetic fiber which absorb little amount of water and loosely attached to the molecules of fiber.
An animal that has thick fur, webbed flippers and blubber to keep it warm would probably live in which of the following biomes:

Answer: A. Blastula
Explanation:
Which of these statements is most likely correct about Location A and Location B?
Location A and Location B will be equally cold because they are on the same
latitude.
Location B will have cooler summers and warmer winters than Location A.
Location A and Location B will be equally warm because they are on the same
latitude.
Location A will have cooler summers and warmer winters than Location B.
Answer:
Location A will have cooler summers and warmer winters than Location B
Explanation:
This is because costal areas are cooler in the summer and warmer in the winter than inland areas along the same latitude

Without naturally occurring carbon dioxide in the
atmosphere, the Earth's global temperature would be 60°
F cooler and life as we know it would not exist. However,
excess carbon dioxide emission from human activity is
harmful because it
-causes decreased cellular respiration in humans.
-causes increased photosynthesis in plants.
-leads to accelerated global climate change.
-leads to increased volcanic activity.
Answer:
Explanation: Carbon dioxide is a greenhouse gas and it is involved with accelerated climate change
How does the release of carbon dioxide by microorganisms benefit plant life?
a.
It reduces the acidity of water in soil, which increases water absorption and provides plants with necessary water.
b.
It increases the acidity of water in soil leading to the breakdown of rocks in soil. This releases nutrients which can be used by plants.
c.
It decreases the acidity of water in soil leading to the breakdown of rocks in soil. This releases nutrients which an be used by plants.
d.
It increases the acidity of water in soil, which decreases water absorption providing plant life with firmer soil for root growth.
Answer:
b.
It increases the acidity of water in soil leading to the breakdown of rocks in soil. This releases nutrients which can be used by plants.
Explanation:
When microorganisms release carbon dioxide into the soil, the acidity of water surrounding soil particles is increased. This increase in acidity allows for rock present in soil to be broken down, releasing minerals into the soil. These minerals are then available for use by plant life.

Which will most likely alter the pH of rain
Answer:
Presence of acidic oxides and other chemicals in air can change the PH value of the Rain.
Explanation:
Generally, PH value of rain remains 5.0. But when the air composition changes due to sulfur dioxide or nitrogen oxides released from automobiles and coal based power plants, the combination of these with rain water makes rainy water more acidic. This results in change of PH value of Rain.
