Answer:
At the very end of the air passages, are clusters of tiny air filled sacs called alveoli . These air sacs are surrounded by small blood vessels called capillaries
Explanation:
The name of the tiny blood vessels that surround the alveoli is Capillaries.
What are capillaries?Capillaries are the places where the exchange of substances between the blood and adjacent tissues takes place. Substance exchange can occur both between the cells that form the vessel wall and across it. Pores present in some types of blood capillaries also act as transfer sites.
Blood capillaries or capillaries as the lining of these little balls are called, are blood vessels of the circulatory system in the form of small tubes. In them, there is a large amount of carbon dioxide that diffuses into the alveolar air.

What information is not given in this equation. It does not show if the reaction is reversible. It does not show the reactants needed for the reaction. It does not show that photosynthesis consists of many separate steps. It does not show the number of molecules required to produce glucose.
6CO2 + 6H2O + light => C6H12O6 + 6O2
A: It does not show if the reaction is reversible.
B: It does not show the reactants needed for the reaction.
C: It does not show that photosynthesis consists of many separate steps.
D: It does not show the number of molecules required to produce glucose
Answer:
C: It does not show that photosynthesis consists of many separate steps.
Explanation:
Photosynthesis is defined as the process through which green plants make their own food by utilizing water and carbon dioxide in the presence of sunlight and produces glucose and oxygen.
The general photosynthetic equation is as follows:
6CO2 + 6H20 + light => C6H12O6 + 6O2
Photosynthetic consists of several steps of the process and the general photosynthetic equation do not show many separate steps that form the product (glucose). Photosynthesis occurs in two major stages: light-dependent and light-independent stage, which in turn consists of a series of reactions that form the products.
Hence, the given equation does not show many separate steps involved in the process of photosynthesis.

Answer: You would expect 25 Kcal of energy stored in trophic level 4.
Explanation:
Energy flow in the ecosystem follows 10% law according to which 10% of the energy in the lower trophic level is transferred to the next trophic level.
In this example grass belongs to the first trophic level, producers.
Energy of grass=25000Kcal
Energy transferred to trophic level 2=10% of 25000=2500
10% of the energy in trophic level 2 is transferred to trophic level 3.
Hence energy at trophic level 3=10% of 2500=250Kcal
Energy transferred to trophic level 4=10% of energy in trophic level 3
=10% of 250=25Kcal
Energy to be stored in trophic level 4=25Kcal
Answer:
There will be 25 Kcal
Explanation:
The 5th - .01% out of 25000 is 2.5
The 4th - .1% out of 25000 is 25
The 3rd - 1% out of 25000 is 250
The 2nd - 10% out of 25000 is 2,500
The 1st - 100% out of 25000 is 25,000
The first part of photosynthesis, known as the light dependent reactions, can occur at any time, but the second step, know as the Calvin Cycle,must have light to occur. True Or False?
Answer:
False
Explanation:
Photosynthesis is the light dependant one. Without light, it can't occur. The Calvin cycle on the other hand is the light-independent reactions in photosynthesis. While it is not directly dependant on the light it is still independently dependant on it because the necessary energy carriers are products of other light-dependent reactions.

List two important scientific changes that affected the human growth rate.
Technology is important scientific changes that affected the human growth rate. It is used to improve technology for harvesting food. Coupled with technology the have also increase good sanitation and that has accelerated growth rate.
What is scientific knowledge?Empirical evidence underpins scientific knowledge. Finds accurate instances of data that can be used as evidence.Scientific knowledge changes over time because new experiments are conducted and new data is introduced best describes the history of scientific knowledge.
For example, much of the information about the seafloor is gathered through indirect methods. Instead, scientists time how long sound waves take to reflect off the ocean floor.
Because all scientific theories require experimental and observational confirmation, all scientific knowledge is vulnerable to change in principle as new data becomes available. Science knowledge's accepted viewpoints might shift throughout time.
Therefore, Technology is important scientific changes that affected the human growth rate.

Based on the data in the graph, how are cyanobacteria responsible for the rise in atmospheric oxygen? State your claim, then make sure to use evidence from biological processes and data from the graph to support your claim.
PLEASE HELP!!!!!!!!!!
Answer:
They release oxygen into the atmosphere.
Explanation:
Cyanobacteria are photosynthetic bacteria that harness the energy from the sun to make food. Using light energy that they trap with photosynthetic pigments, they convert carbon dioxide and water into sugar and oxygen. Therefore, they release oxygen into the atmosphere.
This is clear from the graph, as oxygen levels rise sharply shortly after the first oxygen producing cyanobacteria appear.

Angiosperms are such a successful group of plants because of how well they recruit animals for pollination and the diverse way they disperse their seeds. Describe two ways animals spread angiosperm pollen and two ways fruit is dispersed.
Answer:
- pollen dispersal: insects and birds are able to spread the pollen of flowers for reproduction
- fruit dispersal: many different mammals (including for example mice, kangaroo, and elephants) eat fruits and then disperse their seeds
Explanation:
Pollination is the process of transfer of pollen (i.e. male gametes) from plant male reproductive structures (called anthers) to the plant female reproductive organ (stigma). For example, hummingbirds pollinate flowers no other animal can (nectar of these flowers is used as food source). Similarly, honey bees pollinate flowers by transferring pollen from the male anther of a flower to the stigma of another flower. On the other hand, many animals (such as, for example, mice) eat different types of fruits and then disperse their seeds by excreting them. In addition, there are fruits with hooks that attach to the hair of many mammals and thus they can be dispersed to far away places.
It should be noted that birds and insects are pollinators and can spread angiosperm.
It should be noted that pollination simply means the process of transferring pollen from the anthers to the stigma.
The ways of dispersing fruits can be through pollen dispersal such as insects and birds spreading the pollen of flowers for reproduction.
Also, it can be through fruit dispersal as many different mammals like bats, kangaroos, etc.

Which property of water helps plants to transport water from their roots to their leaves
The tendency of water molecules to get attached to one another helps it in the transport of it from the roots of the plants to the leaves. This tendency is referred to as cohesion.
What is cohesion?The sticking of the particle to one another, this property is called as cohesion.
Water gets transported from the roots to leaves in an upward direction through the vessels called the xylem.
The property of water namely, cohesion allows the water molecule in this movement.
Thus, it can be concluded that cohesion is the property of water helps plants to transport water from their roots to their leaves.

PLEASE ANSWER ASAP. Thank you. QUESTION: How does knowing how a star forms help an astronomer study the origins of the universe?
Answer:
Since stars were made from the Big Bang along with the Universe, they contain the properties that make up the Universe. Some stars are made from the remanants of gas that was made there. Stars are made when gas is pulled towards each other with gravity. Therefore, they are also made of properties from space.
