Explanation:
providing structural support, storing energy and sending cellular communication signals..
polysaccharide are an important class of biological polymers. their function in living organisms is usually structure or storage related.. starch (a polymer of glucose) is used as a storage polysaccharide in plants.

glucose.
oxygen.
water.
DONE
Answer:

Jane has a beaker containing a clear solution. She adds a liquid pH indicator to the clear solution and observes that the solution changes to bright blue. The clear solution in the beaker must be a(an)
Answer: a (weak) acid
Explanation: the solutions are mostly neutral but the pH shown by the indicator as a bright blue means it is slightly acidic meaning the pH is between 6 and 7.6
As the solution turns bright blue on addition of indicator, the solution in beaker must be a weak base.
What is a base?
According to the Arrhenius concept, base is defined as a substance which yields hydroxyl ions on dissociation.These ions react with the hydrogen ions of acids to produce salt in an acid-base reaction.
Bases have a pH higher than seven as they yield hydroxyl ions on dissociation.They are soapy in touch and have a bitter taste.According to the Lowry-Bronsted concept, base is defined as a substance which accepts protons .Base react violently with acids to produce salts .Aqueous solutions of bases can be used to conduct electricity .They can also be used as indicators in acid-base titrations.
They are used in the manufacture of soaps,paper, bleaching powder.Calcium hydroxide ,a base is used to clean sulfur dioxide gas while magnesium hydroxide can be used as an antacid to cure acidity.

A bat wing, an alligator leg, and a human arm are homologous structures.
Which fact about those structures best supports one aspect of theory of evolution?
The fact that the bone structures are similar supports the concept that birds evolved from mammals.
The fact that the bone structures are similar supports the concept that the animals shared a common ancestor.
The fact that the bone structures are completely different supports the concept that those organisms shared a common ancestor.
Answer:
The fact that the bone structures are similar supports the concept that the animals shared a common ancestor.
Explanation:
The similarity of the wings of bats, legs of alligators, and arms of humans in structure is an indication that animals shared a common ancestor according to the evolution theory.
Homologous organs are organs found in different organisms that are similar in structure but different in functionality.
The fact that these organs are similar to each other in morphological structure points to the fact that they might have evolved from the same ancestor according to evolutionists.
The wings of bats, legs of alligators, and arms of humans are all based on the same pentadactyl (five-digit) structure. However, a bat uses its wing to fly, alligators use their legs to crawl, while humans use their arms for a variety of purposes.
The homologous organ is one of the pieces of evidence used to support the evolution theory.

An expiriment was done to determine if the rate at wich a patato cooked depended on the temperature of water in which it was boild. What are the independent and dependent variable??
Answer:
The independent variable is the potato and dependent variable will be the temperature
Explanation:
When this experiment is done it consider about the boiling rate of the temperature which it helps to cook the potato. in other words when you do this experiment you will try different temperature levels on the same type of vegetable which is a potato. so the variable called temperature will be dependent because its the variable that we change. and the variable called potato will be the independent.

how do animals survive in both water conditions
Answer:
they have adapted to the temperatur since water trafers water faster than air. (more info below)
Explanation:
animals also have adaptations to temperature control, as water transfers heat faster than air. At the end of the day, aquatic animals have a lot of adaptations for moving in the water, such as a streamlined design, flippers, and a swim bladder, which acts like a fish ballast.

During the light reactions of photosynthesis, why is a molecule of water split?
to provide energy for the electron transport chain
a.) to provide energy for the electron transport chain
b.) to produce electrons that replace the two electrons that were lost from the chlorophyll molecule
c.) to assist in the process that produces ATP
d.) to form NADPH
Answer:
B
Explanation:
Electrons from photosystem II go through the ECT in the chloroplast, so water is split to replace those electrons.

During mitosis, chromatin condenses into chromosomes, spindle fibers form from one end of the cell to the other, and centrioles organize the spindle fibers. Which stage of mitosis happens next?
Answer:
Metaphase
Explanation:
Mitosis is the cell division that involves the production of daughter cells that are genetically identical to the parent cell. Mitosis is undergone by every living cell and it includes four main stages: Prophase Metaphase, Anaphase, and Telophase.
The description in this question showcases the Prophase stage, which is the first stage of mitosis. The Prophase stage involves the condensation of Chromatin threads into Chromosomes. The mitotic spindle, which contains the microtubules that will separate sister chromatids begins to form. The next phase involves the aligning of chromosomes at the cell's equator, which occurs in the METAPHASE stage.
Answer:
Metaphase

Which of the following climate types is found near the equator?
A tropical climate is found near the equator.
The answer is :
Hot and humid climateIf carbon in the atmosphere increase will carbon on earth increase too?
Answer:
When carbon dioxide concentrations rise, air temperatures go up
When carbon dioxide concentrations rise, air temperatures go up, and more water vapor evaporates into the atmosphere—which then amplifies greenhouse heating.

What are some examples of comparative embryology in evolution?
Answer:
Similarities in structure among distantly related species are analogous if they evolved independently in similar environments. They provide good evidence for natural selection. Examples of evidence from embryology which supports common ancestry include the tail and gill slits present in all early vertebrate embryos.
explain what part of the day condensation usually occurs and why
Answer:
Condensation is the formation of liquid drops of water from water vapor. ... Condensation in the atmosphere usually occurs as a parcel of rising air expands and cools to the point where some of the water vapor molecules clump together faster than they are torn apart from their thermal energy
Explanation:
What is the most environmentally friendly form of building?
A. Concrete
B. Brick
C. Steel
D. Timber
Answer:
D) Timber
Explanation:
Concrete creates a large carbon footprint as carbon dioxide is released during its production. Steel releases air emision like CO, SOx, NOx, PM2. Whereas, brick is made out of clay the heat required for manufacture is usually gained from coal burning releasing emissions into the atmosphere. Although timber contributes to deforestation when managed sustainably has the potential to be carbon neutral/sustainable.
