Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function.
Unicellular organisms include bacteria, protists, and yeast.
a. Why do you think unicellular organisms perform asexual reproduction? (give two reasons)
b. What type of asexual reproduction do bacteria most commonly use?
Answers
Answer:
A)
1: The offspring of the cell will contain the exact genes of the parent by reproducing asexually
2: They can reproduce rapidly by reproducing asexually.
B) Binary fission. One cell simply splits into two identical cells.

1. Blood is at it's highest pressure just when it leaves the heart. Why do you think so?
2. The blood in an artery flows faster and at higher pressure than blood in veins. Why so?
Answers
Answer:
1.Blood pressure can be defined as the pressure of blood on the walls of the arteries as it circulates through the body. Blood pressure is highest as its leaves the heart through the aorta and gradually decreases as it enters smaller and smaller blood vessels (arteries, arterioles, and capillaries).
2. The more rounded the lumen, the less surface area the blood encounters, and the less resistance the vessel offers. Vasoconstriction increases pressure within a vein as it does in an artery, but in veins, the increased pressure increases flow.

Comparing the four most common types of power plants in Alberta (coal, natural
gas, wind, and hydroelectric), which has the lowest efficiency in electricity
generation? and why?
Answers
Answer:
Coal.
Explanation:
Steam power plant has the lowest efficiency in electricity production which can only be run with the use of fossil fuels such as coal. The efficiency of this power plant is the lowest because large amount of coal is converted into smoke and other gases and very less amount of coal into heat energy. This coal is used to produce heat energy which can be used in the heating of water to produce steam. This steam is used to move turbines which turn mechanical energy into electric energy.

B. release heat from large molecules so that the heat can be recycled through the ecosystem
C. can take in carbon dioxide and convert it into oxygen
D. convert molecules of dead organisms into permanent biotic parts of an ecosystem
Answers
Answer:
D
Explanation:
Decomposers are important in the environment because they convert molecules of dead organisms into permanent biotic parts of an ecosystem. So, the correct option is (D).
What are Decomposers?Living organisms such as micro-organisms that convert dead plants and animals into humus are known as decomposers. Fungi and bacteria fall in this category. It recycles and converts the dead matter into humus which mixes with the soil of the forest. It provides essential nutrients to the plants. It is also known as detritivores.
There are four types of decomposers, namely
FungiInsectsEarthwormBacteriaThese types of organisms decompose or break down organic matter such as the remains of dead organisms, carrying out the process of decomposition, which occurs after the death of all living organisms.
They are also called reducers because they are able to remove or degrade dead bodies of organisms and because of their small size they are known as micro consumers.
Thus, Decomposers are important in the environment because they convert molecules of dead organisms into permanent biotic parts of an ecosystem. So, the correct option is (D).

The secondary succession.
Explanation:
It one of the ecological successions of a plant life that take place on the primary or disturbed system as the succession occurs in the preexisting soils as here the preen of the rocky island and the sandy beach is considered to be the primary succession where the coconut is washed by the high tides along with the seaweed.
The secondary succession thus starts to form with the interaction of the and beach as the coconut will continue and grow in the sandy beach as it will get nutrient and moisture firm the soil and gradually develop into a large island of coconut palm trees and thus the rocky beach will get converted to a secondary living community.

Which substance in chloroplasts is a green pigment that absorbs energy for
photosystems?
O A. NADPH
O B. ATP
O C. Chlorophyll
O D. Thylakoids
Answers
Answer:
C. Chlorophyll
Explanation:
Chlorophyll is the green pigment that absorbs the light energy for photosystems.
The substance in chloroplasts that is a green pigment and absorbs energy for photosystems is chlorophyll, which is present in Option C, as chlorophyll is the primary pigment responsible for the green color of most plants as it reflects green light,
What is chlorophyll?Chlorophyll is a type of pigment that is responsible for the green color of leaves, stems, and other plant parts, and it is found in the chloroplasts of plant cells, specifically in the thylakoid membranes, where it plays a central role in photosynthesis, and chlorophyll absorbs light energy from the sun. During photosynthesis, chlorophyll absorbs light energy and transfers it to other molecules in the photosystems, where it is used to generate ATP and NADPH, and these energy-rich molecules are then used in the light-independent reactions of photosynthesis to produce glucose and other organic compounds.
Hence, the substance in chloroplasts that is a green pigment and absorbs energy for photosystems is chlorophyll, which is present in Option C.

You are walking through a mixed evergreen-deciduous forest, where approximately 10 percent of the trees are eastern hemlocks, a species of evergreen tree that casts very deep shade on the forest understory. Interestingly, under every eastern hemlock, you find the same small herbaceous plant species. However, you never observe this species anywhere else, even though a healthy diversity of other species live throughout the forest understory. You expect the small herbaceous species to have _____ growth, _____ sexual maturity, _____ energy expended on seeds, and _____ reproduction. Please choose the correct answer from the following choices, and then select the submit answer button. Answer choices fast; early; high; no vegetative slow; late; low; vegetative slow; early; low; vegetative fast; early; low; vegetative slow; late; high; no vegetative
Answers
Answer: slow; late; low; vegetative
Explanation: Due to the casting of deep shade on the forest understory by eastern hemlock, direct sunlight and other necessities for photosynthesis and other life processes needed by the herbaceous plant species for optimum growth is being deprived.
However, coupled with the nature of these herbaceous plant species, having non-woody stems with their growth above the ground level often dieing off particularly in winter in the temperate zone, makes their growth in that kind of location to be stunted.
Thus, herbaceous plant species with slow growth rate leading to late sexual maturuty while having low expanded energy on seeds due to low photosynthetic rate and low vegetative reproduction should be expected.

- Ectothermic animals use photosynthesis to convert sunlight into energy for cell functions.
- Green plants use photosynthesis to remove oxygen gas from the atmosphere and replenish the earth’s carbon dioxide.
Answers
Answer:
The correct answer is: A) Grass uses photosynthesis to produce glucose, which is used within the grass for growth.
Explanation:
Photosynthesis is the process by which green plants, which include algae, take in the energy from the sun and combines it with carbon dioxide (and water) to form benificial sugars.
Photosynthesis refers to the process by which the green plants, as well as algae, utilize the energy from the sun in combination with the carbon dioxide as well as water to form simple sugars. This is how the harmful gas carbion dioxide can be destroyed and elimanated.

Brown what method he can
use prevent that from happening
Answers
Answer:
Install wood or rebar stakes at least 6 feet-tall at planting time. As the plants grow, tie the stems loosely to the stakes with twine or strips of fabric.The most common cause of leggy seedlings is lack of strong, overhead lighting. Tomato plants become long and spindly when they are reaching for the light. If the light only comes from one direction, then your seedlings not only become leggy, but will also lean towards the light.Generally speaking, in the north, tall plants such as beans, peas, and corn do best on the north side of the garden. Medium size crops such as tomatoes, cabbage, squash, pumpkins, and broccoli in the center of the garden.
