The force of gravity pulls all objects downwards. Which of these statements is correct about this law of science?
A. It is not supported by observations
B. It can be contradicted by data
C. It requires no further experimentations to determine its existence
D. It is a description in nature that will continue to change
Answer:
C
Explanation:
If you drop something on the ground and watch it fall, you are observing gravity at work, so A is not an option. All data proves this law exists, so B is not an option, and it will not continue to change, as it never has changed, so it is not D.

Which of the following is the correct equation for photosynthesis?
a.) CO2 + light + H2O --> O2 + Sugar
b.) CO2 + sugar + H2O --> O2 + light
c.) O2 + light + H2O --> CO2 + Sugar
d.) CO2 + O2 + H2O --> Light+ Sugar
Answer: a
Explanation: light is a energy sourse for the photosintesis and sugar is glucose wich is the food formd at the end of phothosintesis like oxigen..(etc..)....
The answer option with the correct equation for photosynthesis is: A. [tex]CO_2 + light + H_2O --> O_2 + Sugar[/tex]
Photosynthesis can be defined as a biological and chemical process through which living organisms such as green plants (autotrophs), transform light energy (sunlight) into chemical energy.
The correct equation for photosynthesis is given by this chemical equation:
[tex]CO_2 + light + H_2O --> O_2 + Sugar[/tex]
Hence, the necessary input for the process of photosynthesis to take place include the following:
Water ([tex]H_2O[/tex]).Sunlight (light energy).Carbon dioxide ([tex]CO_2[/tex]).
In conclusion, oxygen and sugar are end products (output) of photosynthesis rather being an input.

Why is an overabundance of nutrients harmful to a water supply?
A.
It decreases the number and types of aquatic plants.
B.
It kills all aquatic plants.
C.
It sterilizes water.
D.
It causes excessive aquatic plant growth.
Answer:
d
Explanation:
It leads to a process called as eutrophication in which the aquatic plants grow regularly over the water surface and the living beings living inside the water gets diminished because of the lack of nutrients and the various substances required for the growth.
What is water sterilization ?It is the process in which the harmful substances and contaminants are removed outside the water source such that the water can be removed out from water resources such that they can be made appropriate for drinking.
An overabundance of various nutrient primarily nitrogen along with phosphorus in water begins a process known as eutrophication. The process hammers the growth of other lives present on the sources.
Algae feed on nutrients, growing, spreading and turning out the water green. Algae blooms smells bad, blocks sunlight and even releases out chemicals in certain cases.

Hot and humid climateWhich question would be asked in a dichotomous key?
A. How long are the insect's antennae?
B. Are the insect's antennae longer than its head?
C. Are the insect's antennae long or short?
D. How does the insect use its antennae?
Answer:
B. Are the insect’s antennae longer than its head?
Explanation:
Dichotomous key refers to the tool or method which helps the scientist to identify organisms.
It uses a specific series of questions which help in segregation of organisms and ultimately help the scientist to identify the organism on the basis of the observations or properties share by the organism.
Example of a simple dichotomous key is shown below.
Similarly, insects can have antennae longer or shorter than their heads. Thus, the question "Are the insect’s antennae longer than its head?" would help in segregating insects based on their antennae length.
happy to help ya:)
The statement B is correct. Are the insect’s antennae longer than its head?
What do you mean by dichotomous keys?A dichotomous key is an important scientific tool, used to identify different organisms, based the organism's observable traits. Dichotomous keys consist of a series of statements with two choices in each step that will lead users to the correct identification.
Moreover, for example, in tree identification, a dichotomous key might ask whether the tree has leaves or needles. The key then directs the user down one list of questions if the tree has leaves, and a different question list if it has needles.
Therefore, dichotomous keys are useful for biological classification as well as identification. The word dichotomous is derived from the Greek words meaning “two parts.” Each step in the key provides two contrasting choices about a characteristic.

W the genetic makeup of the plants. Do you think the student made an error, or is there another
explanation?
No, even though it was only a 50% chance of being Rr, it still could have been that both plants got Rr, cause as long as it's greater than a 0% chance it can happen.

Why xylem and phloem are called complex tissues? How are they different from one another?
Answer:
Xylem and phloem are called complex tissues because they are made up of more than one type of cell working together as a unit. The xylem transports H2O and minerals upward from the roots to the leaves, and is composed of tracheid cells which are dead at maturity (no active nucleus, makes the tree stem hard). If plants don't have xylem, they will stay lower to the ground as it is responsible for making the tree grow upward. The ends of the xylem tubes are tapered (pointed), materials are passed along one cell at a time, and the tubes are narrow and continuous. The phloem transports sugars and proteins downward from the leaves to the stems and storage roots. The cells that make up the phloem are called sieve tubules and companion cells. The companion cells have the nucleus and the sieve tubules contain the cytoplasm.
Explanation:
My teacher helped us remember using the phrase "phloem down the river" because it sounds like 'flowing down the river' (to help remember that phloem transports downward and xylem transports upward.)
Based on the pedigree that is shown above, how to describe Fred?
Answer:
The given pedigree analysis shows sex-linked trait where the female work as a carrier and have X linked recessive gene that is [tex]X^{h}[/tex] and the male is normal.
So, Fred will be a male with [tex]X^{h}[/tex][tex]Y[/tex] gene and Fred will be affected with X linked disease which is carried by female.
If, [tex]X^{h}[/tex] gene in the female (Ann) act as a carrier of hemophilia and the male (John) is normal, then Fred will be a male affected with hemophilia (sex linked disease).
Hence, Fred will be affected male with [tex]X^{h}[/tex][tex]Y[/tex] genotype.
